Payroll components and deductions: gross pay to net pay

The components of payroll are the individual elements that make up an employee's total compensation: gross pay, employer-side costs, employee deductions, and net pay. Understanding how each piece works matters most once you are running payroll across more than one country, where these same four categories hold local rates, deductions, and filings that differ by jurisdiction.

The core components of payroll are gross pay, employer-side costs, employee deductions, and net pay, the four categories that turn hours worked or a salary agreement into a paycheck and a set of tax filings. Every payroll cycle, in every country, runs through these four categories, even though the specific line items inside each one change by jurisdiction.

• Gross pay: everything an employee earns before any deduction is taken out, from base salary through bonuses and paid time off.
• Employer-side costs: the employer's share of statutory contributions, unemployment insurance, and other costs that sit on top of gross pay and never appear on the employee's paycheck.
• Employee deductions: the mandatory and voluntary amounts subtracted from gross pay, from tax withholding to retirement contributions.
• Net pay: what is left after every deduction, the amount that actually reaches the employee's bank account.

In any single jurisdiction, a payroll run typically produces ten to fifteen distinct line items once tax withholding, benefits, and voluntary deductions are added on top of base pay. The exact number depends on the country, the employer's benefit offerings, and each employee's elections, which is why a payroll built for one country rarely transfers cleanly to another.

Contractor pay has none of the employer-side contributions listed here; gig payroll explains what applies instead.

Payroll components differ from country to country mainly in statutory contribution rates, mandatory benefits, and the types of deductions required by local law, while the gross-to-net framework, earnings minus deductions equals net pay, stays the same everywhere. Employer contributions alone can range from single digits to over 40% of gross salary depending on the country, which materially changes the total cost of employing someone abroad.

The table below lists employer and employee contribution rates and notable payroll components for a sample of countries we track.

The differences go beyond the headline rate. Across the 196 countries in our Global Employer Burden Index dataset, the median employer social security contribution is 12.6%, and New Caledonia carries the highest employer rate we track, at 36.49%. On the employee side, across the 191 countries in the same dataset, the median contribution is 7%, and Romania carries the highest employee rate we track, at 35%.

International payroll also introduces components that do not exist in a single-country US payroll. Many countries require employers to separate overtime worked in normal daytime hours from overtime worked at night or on weekends and holidays, each carrying its own premium rate. Severance pay, holiday pay, and 13th or 14th-month salary accrue as employer liabilities throughout the year rather than appearing only at termination. Skills development levies, insolvency fund payments, and sector-specific payroll taxes apply in several countries and belong in the employer's total cost calculation.

For a company hiring across multiple countries, calculating each country's payroll components correctly by hand is close to a full-time compliance job. An employer of record (EOR) or a global payroll outsourcing provider typically takes on these country-specific calculations, so you are not building French, German, and Indian payroll expertise in house for a handful of employees. Data security in payroll becomes especially important once employee compensation data crosses borders and falls under regimes like GDPR.

Gross pay is the total amount an employee earns before any deductions, made up of base salary or hourly wages, overtime, bonuses and commissions, allowances, expense reimbursements, and paid time off compensation. It is the starting point every tax withholding, benefit deduction, and employer-side cost is calculated from.

In the US, employees earning at least $684 a week ($35,568 a year) who meet specific duties tests are exempt from overtime under the FLSA. Several states, including California, New York, Washington, Colorado, Alaska, and Maine, set higher salary thresholds that override the federal one, and employers must apply whichever threshold is higher. Getting these calculations right in every jurisdiction you operate in is one of the fastest ways to improve payroll accuracy, since misclassifying overtime or a bonus creates the same tax filing discrepancy anywhere in the world.

Employer-side payroll costs are expenses the company pays on top of an employee's gross pay that never appear on the employee's paycheck, including the employer's share of statutory social contributions, unemployment insurance, and workers' compensation. In the US, these costs add approximately 10% to 15% to gross pay before voluntary benefits, and 25% to 40% above base salary once health insurance and retirement matching are included. Outside the US, the same layer of cost runs from single digits to well over a third of salary, as the country comparison above shows, and it is a major driver of total payroll cost when you compare hiring locations.

Employers in credit reduction states pay higher effective FUTA rates because their states have not repaid federal unemployment loans, and the list of credit reduction states is recomputed annually. Building a compliance framework for payroll that tracks these state-by-state variations matters for any multi-state employer, and the same problem multiplies once you add a second or third country.

Payroll deductions are the amounts subtracted from an employee's gross pay, split between mandatory deductions required by law and voluntary deductions the employee elects, and calculated in a fixed order that determines what the employee actually owes in tax.

1. Determine gross pay for the period.
2. Subtract pre-tax deductions, such as health insurance and retirement contributions.
3. Calculate and withhold income tax using the employee's withholding certificate.
4. Apply additional required taxes, such as an extra Medicare withholding once earnings pass a threshold.
5. Determine state and local income tax based on where the employee works and lives.
6. Subtract post-tax deductions, such as wage garnishments and Roth contributions.
7. Calculate net pay: what remains after every deduction.

Key takeaway: Pre-tax deductions must be subtracted before you calculate payroll taxes. Applying them in the wrong order means over-withholding income tax from every paycheck.

Mandatory deductions include FICA taxes, federal income tax, state and local income tax where it applies, and court-ordered wage garnishments; employers withhold these regardless of employee preference. In the US, employees pay 6.2% Social Security up to $184,500 in 2026 and 1.45% Medicare with no cap, plus an Additional Medicare Tax of 0.9% once wages pass $200,000 for single filers ($250,000 married filing jointly, $125,000 married filing separately). Nine states, Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming, levy no state income tax on wages. Wage garnishments are capped under Title III of the Consumer Credit Protection Act, which limits how much of a paycheck can be garnished each week and blocks termination over a single garnishment.

Not every pre-tax deduction gets the same tax treatment, and this distinction is one of the most common sources of payroll error.

For 2026, employees under 50 can contribute up to $24,500 a year to a 401(k), per IRS Notice 2025-67, with an $8,000 catch-up at 50 and older, and an $11,250 super catch-up for ages 60 to 63 under SECURE 2.0. If a payroll system treats a 401(k) contribution the same as a Section 125 deduction for FICA purposes, Social Security and Medicare get under-withheld and a liability builds with the IRS. The role of audits in payroll is to catch that kind of FICA treatment error before it becomes a tax authority liability.

Every term used here, from accrued time off to zero-hour contracts, is defined in the payroll glossary.

Net pay is the amount an employee takes home after all deductions are subtracted from gross pay: gross pay minus pre-tax deductions, federal income tax, employee FICA, state and local taxes, and post-tax deductions. The walkthrough below uses a US employee as the example, since the deduction order and tax rates are specific to US rules.

Here is how a $75,000 annual salary breaks down for a single filer with no dependents, contributing $300 a month to a 401(k) and $200 a month to health insurance through a Section 125 plan, paid semi-monthly across 24 pay periods.

Social Security and Medicare are calculated on $3,025 (gross minus the Section 125 health insurance deduction), not on the full $3,125, because the 401(k) contribution reduces federal income tax withholding but does not reduce FICA wages. In this example, approximately 21% of gross pay goes to federal, state, and FICA taxes, with another 8% going to the employee's own retirement savings and health insurance; an employee in Texas, which has no state income tax, would take home roughly $100 more per pay period than this example shows. Cloud-based payroll software automates these gross-to-net calculations and applies the correct FICA treatment to each deduction type automatically, which matters more, not less, once you are running the same calculation across multi-currency payroll.

Payroll liabilities are the wages, withheld taxes, employer contributions, and accrued benefits a company owes but has not yet paid, and they sit on the books as liabilities from the moment they are withheld until the money reaches the agency, provider, or court it is owed to. Failing to remit withheld taxes on time triggers IRS deposit penalties of 2% to 15%, depending on how late the payment is, and can create personal liability under the Trust Fund Recovery Penalty for anyone who willfully fails to remit.

The 1099-NEC threshold of $2,000 applies for tax year 2026, raised from $600 under Section 70433 of the One Big Beautiful Bill Act, signed July 4, 2025, and it will be inflation-adjusted starting in 2027.

US federal law sets four separate retention windows for payroll records, and this is the practical floor employers work from, even though some HR teams keep records for seven years to cover every federal and state requirement at once.

Under 29 CFR § 516.7(a), records stored at a central recordkeeping office separate from the worksite must be available within 72 hours of a Department of Labor request; records kept on-site just need to be safe and accessible. Electronic payroll reporting makes retrieving these records during an audit far easier than paper files, and getting them wrong carries the same payroll tax penalties as getting a withholding calculation wrong.

Pay frequency is set by state or country law and by employer preference, with weekly, biweekly, semi-monthly, and monthly the most common schedules. California requires semi-monthly pay for most employees, and New York requires weekly pay for manual workers. Employers with employees in multiple states or countries need to check each jurisdiction's minimum before setting a payroll calendar, especially with remote employees spread across several states.

Time cards work best when pay is distributed on a weekly or biweekly basis, since hourly employees' worked hours need to be reconciled and approved close to when they were worked. A semi-monthly or monthly cycle stretches that reconciliation window relative to the hours being tracked, which is one reason many employers pair hourly roles with the shorter cycle and salaried roles with the longer one.

Once you know how each component and deduction is calculated, the next decision is how to run payroll across every country you operate in without hiring a payroll specialist in each one. Compare payroll systems, or see how the leading global payroll providers compare if you would rather hand these calculations to a provider that already maintains this rate table for every country you hire in.
