Paycheck Calculator 2026 — Take-Home Pay After Taxes

How to Use the Paycheck Calculator

1. Enter your annual gross salary — this is your total compensation before any deductions or taxes. If you are hourly, multiply your hourly rate by your expected annual hours (e.g., $25/hr × 2,080 hours = $52,000).
2. Select your filing status — Single or Married Filing Jointly. This determines your standard deduction and which tax brackets apply. If you are married and file separately, use Single as a close approximation.
3. Choose your pay frequency. Bi-weekly (26 paychecks/year) is the most common in the US, but many employers pay semi-monthly (24/year) or monthly.
4. Enter your 401(k) contribution percentage. Traditional 401(k) contributions are pre-tax — they reduce your federal income tax but do not reduce Social Security or Medicare taxes. The 2026 IRS contribution limit is $23,500 (under 50) or $31,000 (50+, with catch-up).
5. Enter your pre-tax health, HSA, or FSA deductions as an annual dollar amount. Unlike 401(k), Section 125 (cafeteria plan) deductions — including employer-sponsored health insurance premiums, HSA contributions, and FSA contributions — reduce both income tax and FICA taxes.
6. Enter a flat state income tax percentage. If you live in a state with no income tax (Texas, Florida, Washington, Nevada, Wyoming, Alaska, South Dakota, Tennessee, New Hampshire), enter 0. For states with graduated brackets, use your estimated effective state rate or look up your state's flat rate.

How Take-Home Pay Is Calculated

Your gross salary passes through several layers of deductions before becoming your take-home pay. Here is the exact path this calculator follows:

Step 1 — Pre-tax deductions. Your 401(k) contribution and Section 125 pre-tax health/HSA/FSA deductions come out of your gross pay first. These reduce your taxable income for federal income tax purposes, effectively giving you a tax discount on every dollar contributed.

Step 2 — Standard deduction. The IRS allows most taxpayers to reduce taxable income by a standard deduction without itemizing. For 2026, that is $16,100 for single filers and $32,200 for married filing jointly. (The standard deduction increases each year for inflation.)

Step 3 — Federal income tax brackets. The remaining taxable income is taxed in progressive brackets — 10%, 12%, 22%, 24%, 32%, 35%, and 37%. Only the income in each bracket is taxed at that rate — reaching the 22% bracket does not mean all your income is taxed at 22%. This calculator applies the 2026 brackets precisely.

Step 4 — FICA taxes. Social Security (6.2%) and Medicare (1.45%) taxes apply to your gross wages minus Section 125 deductions. Importantly, 401(k) contributions do not reduce FICA wages — only cafeteria-plan deductions do. Employers also withhold a 0.9% Additional Medicare Tax on wages over a flat $200,000 per year, regardless of filing status; your final liability (which uses a $250,000 threshold for married filing jointly) is reconciled on Form 8959 when you file.

Step 5 — State income tax. Applied as a flat percentage on gross wages minus pre-tax deductions, as entered.

Result: Net take-home = Gross − (Federal Income Tax + SS + Medicare + Additional Medicare + State Tax) − 401(k) − Health/HSA/FSA.

Understanding FICA: Social Security & Medicare

FICA (Federal Insurance Contributions Act) taxes fund Social Security and Medicare. Every W-2 employee pays these in addition to federal income tax — they are not part of the income tax bracket system and cannot be reduced by deductions or credits the way income tax can.

Social Security (6.2%): Applies to wages up to the Social Security wage base — $184,500 in 2026. Once your earned wages exceed this threshold, no further Social Security tax is owed for the year. Your employer matches your 6.2% contribution for a combined 12.4% going into the Social Security trust fund.

Medicare (1.45%): Unlike Social Security, Medicare has no wage cap — you pay 1.45% on all covered wages. Again, your employer matches this for a combined 2.9%.

Additional Medicare Tax (0.9%): Individuals earning above $200,000 (single) or $250,000 (married filing jointly) owe an extra 0.9% on earnings above those thresholds. Your employer withholds this once your wages with that employer exceed $200,000 in a year, regardless of filing status — if your total combined income from all sources exceeds the threshold, any remaining liability is reconciled on your tax return.

Self-employed individuals (1099 contractors) pay both the employee and employer halves — a combined 15.3% for Social Security + Medicare — though they can deduct the employer half as a business expense. This calculator covers W-2 employees only.

Pre-tax Deductions That Lower Your Taxes: 401(k), HSA, and FSA

One of the most powerful ways to reduce your tax bill is through pre-tax workplace benefit deductions. Understanding which ones reduce which taxes is key:

Traditional 401(k) contributions reduce your federal (and usually state) taxable income, saving you income tax on every dollar contributed at your marginal bracket rate. However, 401(k) contributions do NOT reduce Social Security or Medicare wages — FICA taxes still apply to your full gross salary before the 401(k) comes out. The 2026 employee contribution limit is $23,500 ($31,000 with catch-up if you are 50 or older). Roth 401(k) contributions are after-tax and do not reduce current taxable income.

Health insurance premiums paid through your employer's Section 125 cafeteria plan reduce both your income tax AND your FICA taxes. This is a double benefit: if your employer deducts $4,800/year for health premiums from your pre-tax paycheck, you save income tax on $4,800 plus roughly $367 in FICA taxes (4.800 × 7.65%). Always use pre-tax payroll deductions for health insurance when available — it is always more efficient than paying premiums after-tax.

Health Savings Accounts (HSA) offer a triple tax advantage: contributions are pre-tax (reducing both income and FICA taxes when made through payroll), grow tax-free, and withdrawals for qualified medical expenses are tax-free. The 2026 HSA contribution limit is $4,300 for self-only coverage and $8,550 for family coverage (plus $1,000 catch-up if 55 or older). HSAs are available only with a High Deductible Health Plan (HDHP).

Flexible Spending Accounts (FSA) are similar to HSAs in tax treatment (pre-tax, reducing income and FICA), but are "use it or lose it" — unused funds generally expire at year end (employers may allow a $640 rollover or a 2.5-month grace period). FSAs can be used with any health plan, not just HDHPs. The 2026 FSA contribution limit is $3,300.

Frequently Asked Questions

• Why does my actual paycheck differ from this calculator's estimate?
  Several factors can cause differences: (1) Your W-4 elections — extra withholding claimed on your W-4 form directly increases how much your employer withholds. (2) Local or city income taxes — this calculator models federal and a flat state rate, but some localities (New York City, Philadelphia, Cleveland, etc.) levy additional income taxes not captured here. (3) Post-tax deductions — Roth 401(k) contributions, after-tax benefits, garnishments, and voluntary deductions come out of your net pay and are not modeled here. (4) Benefits and perks — employer-provided life insurance above $50,000 (imputed income), stock awards, and bonuses may be withheld at different rates. Use this calculator for planning estimates; your actual pay stub is the authoritative source.
• What is the difference between marginal and effective tax rate?
  Your marginal tax rate is the rate applied to your last dollar of income — the highest bracket you reach. At $85,000 gross with a $60,800 taxable income as a single filer, your marginal rate is 22% because that taxable income falls in the 22% bracket. Your effective tax rate (shown in this calculator) is the percentage of your gross salary actually paid in total taxes. It is almost always lower than your marginal rate because lower portions of your income are taxed at lower rates (10% and 12% first). Understanding both is important: your marginal rate tells you the tax cost of earning one more dollar; your effective rate tells you your overall tax burden.
• Should I contribute to a traditional or Roth 401(k)?
  The traditional vs. Roth decision hinges on whether you expect to be in a higher or lower tax bracket in retirement. Traditional 401(k) gives you a tax break now (reduces current taxable income) and you pay taxes when you withdraw in retirement. Roth 401(k) is funded with after-tax dollars (no current benefit) but all growth and withdrawals in retirement are tax-free. If you are early in your career in a lower bracket now and expect higher income later, Roth often wins. If you are in your peak earning years now and expect lower income in retirement, traditional is typically better. Many advisors recommend splitting between both to hedge tax risk.
• I live in Texas (or Florida, Washington, etc.) — should I enter 0% state tax?
  Yes. Nine states have no state income tax on wages: Texas, Florida, Washington, Nevada, Wyoming, Alaska, South Dakota, Tennessee (only on investment income), and New Hampshire (only on investment income). If you live and work in one of these states, enter 0 in the State Income Tax field. Note that some of these states make up for the lack of income tax with higher property taxes or sales taxes — but those are not withheld from your paycheck and are not captured in this calculator.
• How does the calculator handle the Social Security wage cap?
  The Social Security wage base for 2026 is $184,500. This calculator correctly caps Social Security tax at $184,500 × 6.2% = $11,439. For a salary of $85,000, your entire salary is below the cap, so Social Security applies to all FICA wages. If you earn above $184,500, the portion above the cap is exempt from the 6.2% Social Security tax (though you still owe 1.45% Medicare on everything, plus 0.9% Additional Medicare on the portion above $200,000 single / $250,000 married).
• Does contributing more to my 401(k) actually increase my take-home pay?
  Not directly — contributing more to a 401(k) reduces your net paycheck because more goes to the account. However, it reduces the tax you owe, so the net cost to your take-home pay is less than the dollar amount contributed. For example, if you are in the 22% federal bracket and contribute $100 more per month to a traditional 401(k), your take-home pay only decreases by roughly $70-$75 (because you save ~$22 in federal income tax plus some state tax savings), while $100 goes into your retirement account. Over time, the compounding growth makes this a highly efficient use of each dollar.
• Why does my 401(k) not reduce my Social Security and Medicare taxes?
  This is one of the most commonly misunderstood aspects of payroll taxes. Traditional 401(k) contributions are excluded from federal income tax under IRC Section 402(e), but they are explicitly NOT excluded from FICA taxes (Social Security and Medicare) under IRC Section 3121. Congress deliberately left FICA taxes in place on 401(k) contributions so that your future Social Security benefit calculation is based on your full earnings history, not your after-401(k) income. In contrast, Section 125 cafeteria plan deductions (health insurance, HSA, FSA) ARE exempt from FICA taxes under a separate provision (IRC Section 3121(a)(5)(G)), which is why they reduce both income and payroll taxes.
