Sources & Methodology
Annual gross pay − pre-tax deductions = federal taxable income. Federal income tax calculated using 2026 marginal brackets after standard deduction. State tax estimated as effective rate on gross pay. FICA = 6.2% Social Security (up to $184,500 wage base) + 1.45% Medicare. Net pay = Gross pay − Federal tax − State tax − Social Security − Medicare − Pre-tax deductions. Per-paycheck amounts divide annual figures by pay frequency.

How Your Paycheck Is Calculated — Complete 2026 Guide
Your paycheck is the result of a specific series of calculations that every US employer must perform on every pay period. Understanding exactly how your take-home pay is calculated helps you verify your pay stub for accuracy, optimize your W-4 withholding, plan pre-tax contributions to maximize your net pay, and anticipate changes when you get a raise, change states, or update your benefits elections.
The fundamental formula is straightforward: Net Pay = Gross Pay − Federal Income Tax − State Income Tax − Social Security Tax − Medicare Tax − Pre-Tax Deductions − Post-Tax Deductions. But each component has its own rules, rates, and limits that change annually.
Gross Pay — Your Starting Point
Gross pay is your total earnings before any deductions. For salaried employees, gross pay per paycheck is your annual salary divided by the number of pay periods per year. For a $65,000 annual salary paid bi-weekly (26 pay periods), each paycheck’s gross pay is $65,000 ÷ 26 = $2,500 gross.
For hourly employees, gross pay = (regular hours × hourly rate) + (overtime hours × 1.5 × hourly rate). A worker earning $20/hour for 45 hours in a week earns (40 × $20) + (5 × $30) = $800 + $150 = $950 gross for that week.
2026 Federal Income Tax Brackets — How Marginal Rates Work
The United States uses a progressive tax system with seven marginal brackets. This means you pay each rate only on the portion of income within that bracket — not on your entire income. A single filer with $60,000 of taxable income does not pay 22% on all $60,000. They pay 10% on the first $12,400, 12% on the next $38,000, and 22% only on the remaining $9,600.
| 2026 Tax Rate | Single Filers | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 | $0 – $17,700 |
| 12% | $12,401 – $50,400 | $24,801 – $100,800 | $17,701 – $67,700 |
| 22% | $50,401 – $101,050 | $100,801 – $202,100 | $67,701 – $107,850 |
| 24% | $101,051 – $192,600 | $202,101 – $385,200 | $107,851 – $192,600 |
| 32% | $192,601 – $243,950 | $385,201 – $487,900 | $192,601 – $243,950 |
| 35% | $243,951 – $626,350 | $487,901 – $731,200 | $243,951 – $626,350 |
| 37% | Above $626,350 | Above $731,200 | Above $626,350 |
The 2026 standard deduction is $16,100 for single filers, $32,200 for married filing jointly, and $24,150 for heads of household. This amount is subtracted from your gross pay before calculating federal income tax, significantly reducing your taxable income. A single filer earning $65,000 annually pays federal income tax only on $65,000 − $16,100 = $48,900 of taxable income.

FICA Taxes — Social Security and Medicare
FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare programs. Unlike income tax, FICA is a flat percentage with no deductions or brackets. Every employee pays 6.2% for Social Security and 1.45% for Medicare on every paycheck, regardless of filing status or deductions. Your employer matches these exact amounts, contributing another 6.2% + 1.45% on your behalf.
The 2026 Social Security wage base is $184,500 — up from $176,100 in 2025. This means Social Security tax of 6.2% applies only to the first $184,500 of your annual earnings. Once your year-to-date earnings exceed $184,500, Social Security withholding stops for that calendar year. There is no wage cap for Medicare — 1.45% applies to all earnings. High earners above $200,000 (single) or $250,000 (married) pay an additional 0.9% Additional Medicare Tax.
| FICA Component | Employee Rate | Employer Rate | 2026 Wage Cap | Max Annual Employee Tax |
|---|---|---|---|---|
| Social Security (OASDI) | 6.2% | 6.2% | $184,500 | $11,439 |
| Medicare (HI) | 1.45% | 1.45% | No cap | Unlimited |
| Additional Medicare Tax | 0.9% | None | $200K+ (single) | On excess only |
State Income Tax — The Largest Variable in Your Paycheck
State income tax is the most significant variable between paychecks across states. The difference between working in a no-income-tax state like Texas or Florida and a high-tax state like California or New York can amount to several thousand dollars per year at the same salary. For a $65,000 salary, a Texas worker takes home approximately $3,900 more per year than an identical worker in California solely due to state income tax difference.
Nine states have no individual income tax as of 2026: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming. New Hampshire taxes investment income but not wages. Several states use a flat rate: Illinois charges 4.95% on all income, Pennsylvania charges 3.07%, Colorado charges 4.4%. The remaining states use progressive brackets similar to the federal system.
| State Tax Type | States | Example | Annual Impact on $65K Salary |
|---|---|---|---|
| No state income tax | AK, FL, NV, NH, SD, TN, TX, WA, WY | Texas: 0% | $0 withheld |
| Low flat rate | PA (3.07%), IN (3.05%), ND (2.9% top) | Pennsylvania: 3.07% | ~$2,000/yr |
| Moderate flat rate | CO (4.4%), IL (4.95%), UT (4.65%) | Colorado: 4.4% | ~$2,860/yr |
| Moderate progressive | GA (5.49%), NC (4.5%), MI (4.25%) | Georgia: 5.49% | ~$3,569/yr |
| High progressive | NY (10.9%), CA (13.3%), NJ (10.75%) | New York: ~7% eff. | ~$4,550/yr |
Pre-Tax Deductions — How to Legally Increase Your Take-Home Pay
Pre-tax deductions are amounts withheld from your gross pay before federal and state income taxes are calculated. This reduces your taxable income and therefore reduces the income tax withheld from your paycheck. Pre-tax deductions do not reduce Social Security and Medicare taxes — FICA is always calculated on your full gross wages regardless of pre-tax elections.
401(k) and Traditional Retirement Contributions
A traditional 401(k) contribution is the most powerful and commonly available pre-tax deduction. The 2026 401(k) contribution limit is $23,500 for employees under age 50, up from $23,000 in 2025. Employees age 50 and older can contribute up to $31,000 including catch-up contributions.
Every dollar you contribute to a traditional 401(k) reduces your federal taxable income by $1. For a worker in the 22% federal bracket, each $1,000 contributed to a 401(k) reduces federal income tax withholding by $220 per year. The effective cost to your take-home pay is only $780 for each $1,000 saved — the government subsidizes 22% of your retirement savings through reduced withholding. In a state with 5% income tax, the combined tax savings are $270 per $1,000 contributed.
Health Insurance Premiums
Employer-sponsored health insurance premiums paid by the employee are typically pre-tax under a Section 125 Cafeteria Plan. This includes medical, dental, and vision insurance premiums. FSA (Flexible Spending Account) contributions for medical expenses are also pre-tax, with a 2026 limit of $3,400 (up from $3,300 in 2025). HSA (Health Savings Account) contributions are pre-tax for those with high-deductible health plans, with 2026 limits of $4,300 for individual coverage and $8,550 for family coverage.
Roth 401(k) vs Traditional 401(k) — Tax Timing Decision
A Roth 401(k) contribution uses after-tax dollars — it does not reduce current withholding. However, Roth contributions grow tax-free and withdrawals in retirement are tax-free. The decision between traditional and Roth 401(k) depends on whether you expect to be in a higher or lower tax bracket in retirement. If you are early in your career in a relatively low tax bracket, Roth is often advantageous. If you are in your peak earning years in a high bracket, traditional pre-tax contributions provide larger immediate tax savings.
Pay Frequency and Its Effect on Each Paycheck
Your pay frequency determines how your annual gross pay, taxes, and deductions are divided across paychecks. It does not change your annual tax liability — only the timing of payments. Bi-weekly pay (26 paychecks per year) is the most common structure in the US. One practical benefit of bi-weekly pay over semi-monthly pay is that two months each year you receive three paychecks instead of two, which many people use for debt payoff or extra savings. Weekly pay (52 paychecks) produces the smallest individual paychecks but provides the most frequent access to earned wages.
Take-Home Pay by Salary — 2026 Reference Table
The following table shows estimated annual and bi-weekly take-home pay for common salary levels in a no-income-tax state and in California (high tax state) for a single filer with no pre-tax deductions. Use this as a reference to quickly estimate net pay at different income levels.
| Annual Salary | Federal Tax (est.) | FICA | No-Tax State (net/yr) | California (net/yr) | Bi-Weekly (no tax state) |
|---|---|---|---|---|---|
| $30,000 | $1,588 | $2,295 | $26,117 | $23,892 | $1,005 |
| $40,000 | $2,788 | $3,060 | $34,152 | $30,482 | $1,314 |
| $50,000 | $3,988 | $3,825 | $42,187 | $37,012 | $1,622 |
| $60,000 | $5,317 | $4,590 | $50,093 | $43,243 | $1,927 |
| $75,000 | $7,967 | $5,738 | $61,295 | $51,820 | $2,358 |
| $100,000 | $13,317 | $7,650 | $79,033 | $64,533 | $3,040 |

| $150,000 | $27,317 | $11,475 | $111,208 | $84,808 | $4,277 |
How a Raise Affects Your Paycheck
When you receive a raise, you do not lose all the increase to taxes — the progressive system ensures you always take home more money when you earn more. A $5,000 raise for a single filer currently in the 22% federal bracket results in approximately $3,900 more in annual take-home pay (the $5,000 increase minus federal tax of $1,100, minus FICA of $383, and any applicable state tax). You never take home less money due to a raise, despite common misconceptions about “moving into a higher bracket.”
How Overtime Affects Your Paycheck and Tax
Overtime pay is taxed exactly like regular wages — at your marginal federal income tax rate and full FICA rates. There is no special overtime tax rate. However, because overtime is typically paid in larger amounts on specific paychecks, the withholding on those paychecks may appear higher as a percentage. This is because employers use the “annualized” method to estimate annual earnings based on each paycheck’s amount, temporarily placing you in a higher projected bracket for that pay period. The actual annual tax liability is calculated on your full-year income when you file your return, with any over-withholding returned as a refund.
How Bonus and Supplemental Pay Is Taxed
The IRS treats bonus and supplemental pay separately from regular wages for withholding purposes. Most employers use the flat rate method: withhold 22% federal income tax on all supplemental wages under $1 million in a calendar year. This 22% rate is called the supplemental wage withholding rate and is set by the IRS in Publication 15-T.
For supplemental wages above $1 million in a calendar year (highly unusual), the withholding rate jumps to 37% on amounts above $1 million. This affects very high-earning executives and professionals who receive large bonuses on top of high base salaries.
FICA taxes (Social Security 6.2% and Medicare 1.45%) apply to bonus pay the same as regular wages, unless you have already reached the $184,500 Social Security wage base for the year. Once year-to-date earnings exceed $184,500, no additional Social Security tax is withheld on that year’s remaining pay including bonuses.
Aggregate Method vs. Flat Rate Method
Some employers use the aggregate method instead of the flat 22% rate. With the aggregate method, your employer adds the bonus to your regular paycheck, calculates total withholding on the combined amount using the normal wage withholding tables, then subtracts the withholding already taken from your regular wages. This can result in higher or lower withholding than the 22% flat rate, depending on your income level and filing status. Employees in lower income brackets may actually have less withheld under the aggregate method, while those in higher brackets may have more withheld.
Neither method changes your actual annual tax liability — only the timing of withholding across the year. Over-withheld bonus taxes are returned as a tax refund when you file your annual return.
