Payroll mistakes are more common than most businesses realize, and the cost of getting payroll wrong goes well beyond the correction itself. About 33% of employers make payroll errors each year, according to data cited by Thomson Reuters, based on IRS research. The average cost of a single payroll error is $291. Cumulative payroll mistakes can drain up to $922,000 annually in lost productivity and correction time alone for a business with 1,000 employees, according to Ernst and Young’s survey titled “EY survey: Payroll errors average $291 each, impacting the economy." Payroll leakage from inefficiencies and errors can account for 2% to 5% of total payroll costs, according to KPMG’s report titled “Payroll Intelligence for the Agentic Era.”

The most common payroll mistakes fall into three categories. The first group includes classification and calculation errors. These include misidentifying workers, miscalculating wages, and mishandling overtime. The second group is tax and compliance failures. These include missing deadlines, filing incorrect forms, and ignoring multi-jurisdiction requirements. The third is process and policy gaps, covering poor recordkeeping, weak internal controls, and inadequate data security.

This guide covers all 20 of the most common payroll mistakes. It explains the consequences they create, how to fix them when they happen, and the most effective ways to prevent them from going forward.

The 20 most common payroll mistakes are listed below.

  1. Misclassifying employees and contractors: Treating a worker as an independent contractor when they legally qualify as an employee triggers tax penalties, back pay liability, and FLSA (Fair Labor Standards Act) violations.

  2. Incorrect wage and hour calculations: Errors in base pay, commissions, or bonuses create underpayments or overpayments that are costly and time-consuming to reverse.

  3. Overtime pay miscalculations: Failing to calculate overtime correctly under FLSA rules, or not tracking daily and weekly overtime in applicable states, exposes businesses to wage claims.

  4. Inaccurate payroll tax withholding and reporting: Withholding the wrong federal or state tax amounts, or reporting them incorrectly on Forms 941 and W-2, leads to penalties from tax authorities.

  5. Missing payroll tax filing or deposit deadlines: Late federal deposits carry IRS penalties ranging from 2% to 15% of the unpaid amount, depending on how late the deposit is.

  6. Failure to report all taxable employee compensation: Excluding bonuses, fringe benefits, or non-cash compensation from taxable income causes under-reporting and triggers audit exposure.

  7. Using incomplete or incorrect employee information: Wrong Social Security numbers, outdated W-4 data, or transposed EINs (Employer Identification Numbers) cause filings to be rejected and year-end reporting to fall apart.

  8. Poor time tracking and attendance management: Inaccurate time records and timecard approval delays produce incorrect wage payments and leave businesses unable to defend pay calculations in disputes.

  9. Failure to maintain accurate payroll records: The FLSA requires employers to retain three years of payroll records. Many states require longer retention periods. Gaps create serious audit risk.

  10. Errors in payroll deductions, benefits, and contributions: Miscalculating 401(k) contributions, health premiums, or FSA (Flexible Spending Account) deductions creates financial discrepancies that are difficult to unwind mid-year.

  11. Improper handling of wage garnishments: Different rules govern child support, tax levies, and creditor garnishments. Failing to process them correctly exposes the employer to court sanctions.

  12. Ignoring state, local, or multi-jurisdiction payroll requirements: Remote workers and multi-state teams generate complex, overlapping tax obligations that a single-state payroll process cannot handle.

  13. Payroll processing delays or inconsistent payroll scheduling: Late or inconsistent pay cycles damage employee trust and breach state wage payment timing laws that specify how frequently employees must be paid.

  14. Errors in final paycheck calculations: Miscalculating termination pay, accrued PTO (Paid Time Off) payouts, or notice-period wages creates immediate legal exposure, particularly in states with strict final pay laws.

  15. Failure to account for PTO and leave policies: Incorrectly tracking or paying out PTO, statutory sick leave, or parental leave generates inaccurate payroll records and potential employment tribunal exposure.

  16. Lack of standardized payroll policies and internal controls: The risk of human error, duplicate payments, and fraud increases substantially without documented procedures and separation of duties.

  17. Overlooking payroll compliance updates and labor law changes: Minimum wage increases, FLSA threshold changes, and state-level legislative updates affect payroll calculations and must be reflected promptly.

  18. Weak payroll data security and confidentiality practices: Payroll data contains Social Security numbers, bank account details, and salary information. Poor access controls create data breach exposure.

  19. Neglecting payroll processing factors such as holidays and bank closures: Federal and bank holidays shift deposit deadlines and payment dates. Missing these cutoffs causes late payments and potential penalties.

  20. Rushing payroll processing without proper review: Skipping the pre-payroll audit step is consistently where avoidable errors originate. About one in five payrolls contain errors, according to Ernst & Young research.

1. Misclassifying employees and contractors

Misclassifying a worker as an independent contractor when they legally qualify as an employee is one of the costliest payroll errors a business can make. The IRS and the Department of Labor use a multi-factor test to determine worker status. A title or a contract that says 'contractor' does not override how the working relationship actually functions.

The worker is likely an employee if the business controls how, when, and where the work is done. Misclassification results in back taxes, back pay, unpaid employer FICA (Federal Insurance Contributions Act) contributions, FLSA penalties, and, in serious cases, personal liability for business owners. The risk is higher than ever, given the growth of gig and remote work arrangements.

2. Incorrect wage and hour calculations

Errors in calculating regular wages (hourly pay, salary, commissions, or bonuses) are among the most frequent payroll mistakes and result in either underpayment or overpayment. Underpayment exposes the employer to wage claims under the FLSA and equivalent state laws, some of which carry double-damages provisions.

Overpayment is also a problem; recovering excess pay from employees is legally constrained and practically difficult. Calculation errors typically stem from manual data entry, incorrect pay rates in the system, or failure to update pay following a salary change. Running a rate audit at the start of each payroll cycle catches most of these before they become claims.

3. Overtime pay miscalculations

Failing to calculate overtime correctly is a frequent FLSA violation, and it is more difficult than simply applying 1.5x pay after 40 hours in a week. Non-exempt employees are entitled to overtime for every hour worked beyond 40 in a workweek, but some states, California being the most prominent, calculate overtime daily as well.

Rounding errors in payroll systems can quietly underpay employees over time. Bonuses and commissions that form part of the regular rate of pay also affect the overtime calculation, which many employers miss. A job title that includes 'manager' or 'supervisor' does not make someone exempt, but their actual duties and salary level under the FLSA's duties tests do.

4. Inaccurate payroll tax withholding and reporting

Errors in calculating, withholding, depositing, or reporting payroll taxes lead to IRS and state agency penalties and, in some cases, trigger formal audits. Common errors include applying the wrong federal income tax withholding table and using outdated state tax rates. Others include failing to update withholding after an employee submits a new W-4 and mismatching totals between Form 941 quarterly returns and annual W-2 filings.

Incorrect Social Security numbers and transposed EINs cause filings to be rejected outright. The correction process is time-consuming and draws attention from tax authorities, so catching withholding errors before filing is always preferable to correcting them after.

5. Missing payroll tax filing or deposit deadlines

Late payroll tax deposits trigger automatic IRS penalties scaled to how late the deposit is. 2% for deposits up to 5 days late, rising to 15% for amounts unpaid more than 10 days after the first IRS notice. Most employers also have state and local deposit deadlines that run on different schedules.

Missing one deadline increases the chance of missing others, since the administrative burden of corrections compounds. The IRS EFTPS (Electronic Federal Tax Payment System) allows deposits to be scheduled in advance, which removes most of the execution risk. Building federal and state due dates into a shared payroll calendar with advance reminders eliminates the most common cause of missed deadlines.

6. Failure to report all taxable employee compensation

Not all taxable compensation arrives through the regular payroll cycle, and failing to include bonuses, performance incentives, fringe benefits, or non-cash awards in reportable income is a material under-reporting error. Common missed items include the value of employer-provided vehicles used for personal travel, group-term life insurance coverage above $50,000, moving expense reimbursements, and gift cards.

The IRS treats most non-cash awards and employer-provided benefits as taxable wages unless a specific exclusion applies. Under-reporting taxable compensation increases audit risk and, when discovered, results in the employer owing back taxes on the unreported amounts, plus interest and penalties.

7. Using incomplete or incorrect employee information

Missing or inaccurate employee data at the point of onboarding creates payroll errors that can persist for months before they are identified. Wrong Social Security numbers, incorrect bank account details for direct deposit, outdated W-4 withholding elections, and missing state tax forms all affect processing accuracy.

Additional complexity arises from incorrect tax residency status, wrong currency accounts, and missing work authorization data for businesses with international workforces. Setting up a structured onboarding checklist that verifies all required payroll data before the first pay run closes most of these gaps before they cause problems.

8. Poor time tracking and attendance management

Inaccurate time records are the single most frequent category of payroll input error, and they affect both wage accuracy and compliance. Time and attendance errors occur more than once per employee annually, totaling over 1,139 errors per 1,000 employees each year, according to Ernst & Young’s report titled “EY survey: Payroll errors average $291 each, impacting the economy."

 Approval bottlenecks, where managers delay approving timecards and force payroll teams to rush, are where most of these errors originate. Manual timesheets amplify the problem. Automated time tracking integrated with the payroll system is the most effective fix for hourly workforces and businesses operating across time zones or locations.

9. Failure to maintain accurate payroll records

Incomplete or poorly maintained payroll records create audit risk, compliance violations, and an inability to defend pay calculations in wage disputes. The FLSA requires employers to retain records covering hours worked, pay rates, total wages paid, and payroll dates for at least three years. Many states impose retention requirements that go beyond three years.

Payroll records also need to be detailed enough to reconstruct any pay period on request. Businesses that shift payroll systems without migrating historical records or that rely on spreadsheets without version control are the most exposed. A documented records retention policy and a system that stores records in a queryable format are both required.

10. Errors in payroll deductions, benefits, and contributions

Incorrect handling of pre-tax and post-tax deductions, retirement contributions, health insurance premiums, and flexible spending account contributions causes financial discrepancies that are difficult to reverse mid-year. 401(k) contribution errors are particularly disruptive because they may trigger IRS correction programs, EPCRS (Employee Plans Compliance Resolution System), and require refund distributions or additional contributions to plan participants.

Benefits deduction errors also affect employees' net pay without their awareness, which damages trust when they notice. A benefits-to-payroll integration that removes manual re-entry of deduction amounts is the most reliable prevention. Reconciling deduction registers against benefits carrier invoices each month catches mismatches before they accumulate.

11. Improper handling of wage garnishments

Wage garnishments are legal orders requiring the employer to withhold a portion of an employee's wages for debt repayment, and failing to process them correctly exposes the employer to court sanctions as well as the employee. Different rules govern different types of garnishments. Child support orders follow Title III of the Consumer Credit Protection Act and have their own withholding limits.

Federal tax levies, state tax levies, creditor garnishments, and student loan garnishments each have distinct priority rules, withholding caps, and remittance schedules. Employers who fail to withhold, remit late, or calculate the wrong amount can be held liable for the missed amounts. A centralized garnishment process with clear ownership and a compliance calendar is essential for any business with more than a handful of employees.

12. Ignoring state, local, or multi-jurisdiction payroll requirements

Businesses with employees working across multiple states, cities, or countries face overlapping payroll tax and employment law obligations that a single-jurisdiction payroll setup cannot handle. Remote work has substantially increased multi-state exposure for businesses that previously only had to think about one state. Each state where an employee works may create payroll tax nexus, registration requirements, and distinct minimum wage, overtime, and leave obligations.

Some cities and counties impose their own payroll taxes on top of state taxes. Cross-border payroll adds permanent establishment risk and social insurance obligations for international businesses. Multi-jurisdiction payroll requires either a payroll system built for it or specialist external support. Attempting to manage it manually is where compliance failures begin.

13. Payroll processing delays or inconsistent payroll scheduling

Late payroll processing and inconsistent pay schedules breach state wage payment timing laws and damage the employee trust that took significant time to build. Most states specify the maximum permissible gap between work performed and wages paid, and some require payment within a set number of days of a payroll period closing.

A missed payroll run or a delayed payment cycle can constitute a wage violation regardless of whether it was intentional. Inconsistency also has a compounding effect on employee financial planning, particularly for hourly workers. Establishing a fixed payroll calendar with processing deadlines clearly defined and building buffer time before each pay date prevents most scheduling failures.

14. Errors in final paycheck calculations

Final paycheck errors carry the highest legal exposure of any payroll mistake because termination pay laws in many states are strict, fast-moving, and carry automatic penalties for noncompliance. California, for example, requires final wages for involuntary terminations to be paid on the day of separation. Several other states require final pay within 24 to 72 hours. Errors typically involve miscalculating accrued PTO payouts, including or excluding the final day of work, or applying the wrong commission or bonus treatment to the termination date. Notice-period wage obligations add further complexity. Having a documented final pay checklist that runs through each element (regular wages, overtime, accrued leave, deductions, and garnishments) at the point of every termination is the clearest prevention.

15. Failure to account for PTO and leave policies

Incorrect tracking or payout of paid time off, statutory sick leave, and parental leave creates payroll inaccuracies and leaves businesses exposed to employment law claims. The complexity comes from layering federal, state, and local leave requirements on top of company policy. The FMLA (Family and Medical Leave Act) sets federal minimums. State and city sick leave laws add their own accrual rules and payout requirements.

Paid parental leave entitlements are expanding across states. A PTO balance that is tracked in a spreadsheet separately from the payroll system is a reliable source of reconciliation errors at year-end and at termination. Integrating leave management directly into the payroll system so that accruals and payouts calculate automatically removes the manual reconciliation step entirely.

16. Lack of standardised payroll policies and internal controls

The absence of documented payroll procedures and separation of duties is the root cause of most recurring payroll errors and the main vulnerability that enables payroll fraud. Payroll runs inconsistently across pay periods and across whoever happens to be processing it that cycle, without written policies. This lack of written policies means one person should not both process payroll and approve it without a separation of duties. A single point of failure or dishonesty can go undetected for months.

Internal controls include a formal approval chain, a pre-payroll review against the prior period, a reconciliation step before funds are released, and an independent post-payroll audit. The American Payroll Association recommends treating payroll as a financial control function, not just an HR administrative task.

17. Overlooking payroll compliance updates and labor law changes

Payroll compliance is not static, and businesses that treat their payroll setup as a one-time configuration rather than an ongoing compliance obligation consistently fall behind. The federal minimum wage has been $7.25 since 2009, but more than 30 states have higher state minimums, many of which increase annually. FLSA overtime salary thresholds have changed and are subject to further revision.

State-level leave mandates, pay transparency laws, and pay frequency requirements all shift with legislative cycles. Social insurance rates, payroll tax thresholds, and employment law obligations are updated on a country-by-country basis. Assigning a named owner to compliance monitoring, or outsourcing to a provider that manages updates automatically, is the only reliable way to stay current.

18. Weak payroll data security and confidentiality practices

Payroll data is among the most sensitive information a business holds, and inadequate security controls create exposure to data breaches, identity theft, and regulatory penalties under data protection laws. Payroll files contain Social Security numbers, bank account details, salary information, home addresses, and, in some cases, medical or disability data tied to leave or benefits.

Access should be restricted strictly to personnel who require it. Shared login credentials, unencrypted payroll exports, and payroll data stored in general-access folders are the most common vulnerabilities. Businesses operating internationally must also comply with GDPR (General Data Protection Regulation) or equivalent data protection regulations that impose specific requirements on how employee payroll data is stored, transferred, and retained.

19. Neglecting payroll processing factors such as holidays and bank closures

Federal holidays, bank closures, and payment system cutoff times shift payroll processing deadlines in ways that, if not accounted for in advance, cause late payments and missed tax deposits. Most payroll systems and banks require ACH (Automated Clearing House) payroll submissions one to two business days before the intended pay date. A federal holiday that falls on a Friday payday means the submission deadline may be Wednesday.

Businesses that process payroll on a fixed-day schedule without regularly checking the calendar for each period often find themselves processing on days when the banking system cannot settle funds. Building a payroll processing calendar at the start of each year, marking every federal holiday and the corresponding adjusted submission deadline, eliminates this error.

20. Rushing payroll processing without proper review

Skipping the pre-payroll review step is the most avoidable cause of payroll errors, and it consistently occurs when payroll processing is left with too little time before the deadline. A pre-payroll audit should compare the current cycle against the prior period and flag new starters and leavers. It should also verify one-off payments such as bonuses or commissions, check deduction totals against benefits registers, and confirm any employees on leave or adjusted schedules.

Businesses using traditional payroll processes without employee verification can experience roughly one in five payrolls containing errors, according to Ernst & Young research. Running payroll one to two days before the required submission date rather than on the day creates enough buffer to catch and correct errors before they reach employees.

What are the consequences of payroll mistakes?

The consequences of payroll mistakes include employee dissatisfaction, compliance risks, tax penalties and fines, back pay claims, reputational damage, negative impact on company culture, and inaccurate financial reporting.

Employee dissatisfaction

A missed or incorrect paycheck is one of the most direct ways a business damages the relationship with its workforce. 86% of employees would face a negative financial impact from a single missing or delayed paycheck, according to a Morning Consult survey commissioned by Paycom. The downstream cost of a payroll mistake extends well beyond the correction for businesses that invest heavily in recruitment and retention.

Compliance risks

Payroll errors that breach FLSA, state wage laws, or tax regulations do not just create financial liability but also formal compliance exposure that can trigger audits and investigations. The IRS, the Department of Labor's Wage and Hour Division, and state labor agencies all have enforcement mechanisms that can be triggered by payroll complaints. The scope typically extends beyond the original error once an investigation opens.

Tax penalties and fines

The IRS assesses penalties for late deposits, incorrect withholding, and filing errors, and those penalties compound the longer they go uncorrected. Late deposit penalties start at 2% and escalate to 15%. Failure-to-file penalties add 0.5% per month on unpaid amounts. State tax authorities run parallel penalty regimes. The cumulative effect of repeated payroll tax errors is a penalty exposure that rapidly outweighs the administrative cost of getting payroll right in the first place.

Back pay claims

Underpaid employees can file wage claims under the FLSA or state wage laws. Some states allow employees to recover double or triple damages on top of the unpaid amount. State statutes of limitations for wage claims typically run two to three years, meaning an error that went unnoticed can generate back pay liability across an extended period. Underpayment claims can also be filed collectively if the error affected multiple employees, which substantially increases the exposure. Wage claims filed with the Department of Labor or through private litigation are both common enforcement routes.

Damaged reputation

Recurring payroll problems become a reputational issue when current or former employees discuss them publicly, whether in reviews, on social platforms, or in industry networks. A reputation for payroll unreliability reduces the applicant pool for businesses in sectors where talent is competitive. Persistent payroll failures also attract media coverage, particularly where large numbers of low-wage workers are affected in some industries and geographies. Reputational damage from payroll issues is slow to repair because it reflects on operational competence, not just a one-time error.

Negative impact on company culture

Payroll errors erode the basic contract between employer and employee, and their effect on team morale and psychological safety compounds over time. 91% of HR professionals believe payroll mistakes break trust between employees and employers, according to a white paper published by Paycom titled “What Employees Want: Overlooked Insights in Employee Engagement.” 

It affects engagement and productivity well beyond the individuals directly affected once trust in payroll reliability is lost. Managers who field complaints about pay errors spend time managing morale rather than work. The organizational cost is real and largely invisible in financial statements.

Inaccurate financial reporting

Payroll errors that are not caught and corrected in the same period flow through to financial statements, creating misstatements in labor costs, tax liabilities, and accruals. For businesses undergoing audits, applying for financing, or preparing for sale, inaccurate payroll data in the accounts creates material reconciliation problems. Payroll liabilities that are understated affect the balance sheet. Over- or underaccrued wages affect the income statement. Restating financial figures because of payroll errors are expensive and, in regulated industries or public companies, carry their own compliance consequences.

How to fix a payroll mistake?

To fix a payroll mistake, identify and document the error, notify affected employees promptly, issue a correction payment or adjustment, and file amended returns if any tax submissions were affected.

The methods to fix a payroll mistake are listed below.

  • Identify and document the error: Establish exactly what went wrong, which pay periods are affected, and which employees are involved. Document the root cause, not just the symptom, so the same error does not recur in the next cycle.

  • Notify affected employees promptly: Employees have a right to know about errors in their pay. A brief, factual explanation of what happened and when it will be corrected maintains trust better than silence. Most employment lawyers recommend notifying employees in writing and keeping a record of the communication.

  • Issue a correction payment or adjustment: Issue an off-cycle correction payment as soon as possible, rather than rolling the correction into the next regular cycle for underpayments. Recovery is governed by state law for overpayments. Some states restrict how much can be deducted per pay period, and employees must be notified in writing before any deductions are made.

  • File amended returns if tax submissions were affected: File a corrected Form 941-X (for federal payroll tax corrections) or the equivalent state form if incorrect withholding or reporting has already been submitted to the IRS or a state tax authority. The sooner the correction is filed, the lower the penalty exposure for W-2 errors, and issue a W-2c.

What are the best ways to prevent payroll errors?

The best ways to prevent payroll errors include understanding complex tax laws, establishing clear policies, tracking time and attendance accurately, conducting pre-payroll audits, outsourcing to specialists, automating processes, and validating data in real-time.

The best ways to prevent payroll errors are discussed below.

  • Understanding complex tax laws: Payroll tax obligations change at the federal, state, and local levels continuously. Assigning clear ownership of compliance monitoring ensures that rate changes, threshold adjustments, and new filing requirements are captured before they affect a live payroll run. Subscribing to IRS, Department of Labor, and state agency update notifications keeps the owner informed in real time.

  • Establishing clear payroll policies: Documented payroll procedures covering the full cycle, from data submission cut-offs to approval chains to post-run reconciliation, reduce variability and create a consistent standard against which errors can be identified. Policies should also cover overpayment recovery, garnishment processing, and data access controls.

  • Tracking time and attendance: Automated time tracking integrated directly with the payroll system eliminates manual re-entry of hours and removes the approval-bottleneck problem that causes rushed processing. Accurate time data is the foundation of accurate pay for hourly workforces in particular.

  • Conducting pre-payroll audits: A structured pre-payroll review comparing the current cycle to the prior period, checking new starters and leavers, verifying one-off payments, and reconciling deduction totals against benefits registers catches most errors before they reach employees. Building this step into the payroll schedule with a fixed buffer before the submission deadline makes it sustainable.

  • Outsourcing payroll: Outsourcing to a payroll provider or PEO (Professional Employer Organization) transfers compliance responsibility and benefits from purpose-built tax update systems for businesses without dedicated payroll expertise. This is particularly valuable for multi-jurisdiction payrolls and international teams.

  • Automating payroll processes: Payroll automation reduces the manual intervention points where human error enters. Tax rate updates, statutory deduction calculations, and direct deposit submissions can all be automated, removing the need for payroll teams to manually manage each element every cycle.

  • Validating data in real-time: Payroll systems that flag anomalies during data entry (outlier hours, duplicate entries, benefit deduction mismatches) catch errors at input rather than after processing. Real-time validation is a function of system quality and requires investing in payroll technology that does it, or a provider whose platform includes it.

When does outsourcing payroll make more sense than managing it in-house?

Outsourcing payroll makes more sense than managing it in-house when payroll complexity outpaces the internal team's capacity to keep up with it, whether that is through headcount growth, geographic expansion, or increasing compliance overhead.

Specific conditions that favor outsourcing include operating across multiple states or countries and dealing with a high rate of employee classification complexity. Other indicators include repeated payroll errors under an in-house process or a lack of a dedicated payroll specialist with current tax and employment law knowledge. A one-person HR team managing payroll for 80 employees across three states is a high-error-risk situation that outsourcing resolves directly.

The cost of outsourcing is frequently lower than the combination of in-house labor costs, software licensing, and the penalty exposure of repeated errors. The calculation should factor in correction costs and compliance risk, not just the headline outsourcing fee for businesses evaluating whether to outsource.

What happens if an employer makes a payroll mistake?

If an employer makes a payroll mistake, the consequences depend on the type and severity of the error. They typically include a legal obligation to correct the error, potential penalties from tax authorities, and exposure to wage claims from affected employees. The employer must amend returns for submitted tax errors. Back pay is required, and some states impose automatic penalties for wage underpayments. The employer holds primary legal responsibility for payroll accuracy unless a service agreement transfers specific liability to the provider.

How long does a company have to fix a payroll error?

The deadline to fix a payroll error depends on its nature. Most employment lawyers recommend correcting it in the next pay cycle or sooner for wage underpayments. The IRS allows employers to file a corrected Form 941-X within three years of the original filing date for tax filing errors. State deadlines for correcting wage errors differ, as some require same-period corrections while others permit a later cycle. Quicker corrections reduce penalties and minimize employee impact.

What is the difference between a payroll error and payroll fraud?

A payroll error is an unintentional mistake in calculating, processing, or reporting pay, such as a misclassification, a calculation error, or a missed deadline. Payroll fraud is the intentional manipulation of the payroll system for financial gain. Common forms of payroll fraud include ghost employees (fictitious workers added to the payroll), timesheet fraud (claiming hours not worked), and payroll diversion (redirecting direct deposits to a fraudulent account).

Can I fix a payroll mistake after submitting it to the IRS or a state agency?

Yes, you can fix a payroll mistake after submitting it to the IRS or a state agency. The correction form is Form 941-X for federal payroll taxes, which amends the Employer's Quarterly Federal Tax Return. W-2 errors are corrected with a W-2c. State agencies have their own equivalent correction forms for payroll audit mistakes. Filing the correction promptly reduces the penalty that applies to the period of non-compliance. The employer can request a refund or apply the overpayment against future deposits if the error results in an overpayment of federal taxes.

What happens if an employee refuses to pay back an overpayment?

If an employee refuses to repay an overpayment, most US states permit recovery, but many impose restrictions. Common limits include capping deductions per pay period and requiring written notice to the employee before deductions start.  Some states prohibit deductions from wages for overpayment recovery without the employee's written consent. The employer may need to pursue repayment through a civil claim in those cases.

Is a payroll service liable for its own mistakes?

Whether a payroll service is liable for its mistakes depends on the terms of the service agreement. The employer is primarily responsible for payroll accuracy, even when using an external provider. Payroll service contracts often limit the provider's liability and exclude penalties for incorrect client information. Some providers offer error guarantees for their mistakes, but these usually do not cover client-submitted errors. It is crucial to review liability and indemnification clauses in the service agreement before hiring a payroll provider. 

What law governs payroll mistakes?

The law that governs payroll mistakes are FLSA (DOL enforcement, classification, overtime, recordkeeping), IRC (IRS enforcement, FICA, FUTA, withholding), and state wage payment statutes.

If an employer makes a payroll mistake, who is responsible for covering the cost?

The employer retains ultimate responsibility for payroll matters, irrespective of the underlying cause. This includes the regulations related to permissible deductions, variations by state, and the necessity for written consent.

What should I do if my employer keeps making payroll mistakes?

If your employer keeps making payroll mistakes, document your concerns in writing. Next, escalate the issue to HR in writing. Approach senior management if unresolved. Contact the DOL Wage and Hour Division if necessary, followed by your state labor agency. Remember, pursuing liquidated damages may be an option if your rights are violated, providing potential compensation for losses incurred.
