Taxes & Deductions Summary
What Salary & Tax Calculator Does
Your paycheck is reduced by several separate things that people tend to lump together: federal income tax, Social Security, Medicare, state and sometimes local income tax, and any pre-tax deductions such as a 401(k) or health premium. They follow different rules and stop at different points.
Federal income tax is progressive — each layer of income is taxed at its own rate, so a raise never reduces your take-home pay. Social Security is flat at 6.2% but stops entirely once you pass the annual wage base. Medicare is flat at 1.45% with no cap at all, plus an extra 0.9% above a fixed threshold that has never been adjusted for inflation.
This calculator applies the tax year 2026 federal brackets and standard deduction published by the IRS, the 2026 Social Security wage base published by SSA, and a flat state rate you supply. Read the limitations before treating the result as your actual paycheck.
How to Use Salary & Tax Calculator
- Select your pay period (Annual Salary, Hourly Wage, or Monthly Pay)
- Enter your gross earnings and hours worked per week
- Choose your tax filing status (Single or Married Filing Jointly)
- Input your estimated state tax rate and 401(k) contribution percentage
- View your estimated net paycheck across annual, monthly, bi-weekly, and hourly frequencies
Formula Used by Salary & Tax Calculator
Federal income tax (progressive brackets)
tax = Σ (income within each bracket × that bracket's rate)
- taxable income
- Gross pay − pre-tax deductions − standard deduction
- Σ
- Each layer is taxed separately; only income above a threshold is taxed at the higher rate
Worked example
A single filer, $75,000 gross, no 401(k), taking the 2026 standard deduction of $16,100.
- Taxable income: 75,000 − 16,100 = 58,900
- First $12,400 at 10% = $1,240
- Next $38,000 (12,400 → 50,400) at 12% = $4,560
- Remaining $8,500 (50,400 → 58,900) at 22% = $1,870
Result: Federal income tax = $7,670. That is 10.2% of gross, even though this person is "in the 22% bracket".
FICA — Social Security and Medicare
FICA = 6.2% × min(wages, 184,500) + 1.45% × wages + 0.9% × max(0, wages − threshold)
- 184,500
- The 2026 Social Security contribution and benefit base. Earnings above it are not taxed for Social Security
- threshold
- $200,000 single / $250,000 married filing jointly for the Additional Medicare Tax. Fixed by statute, never indexed
Worked example
The same $75,000 salary.
- Social Security: 75,000 × 6.2% = $4,650
- Medicare: 75,000 × 1.45% = $1,088
- Additional Medicare: income is below $200,000, so $0
Result: FICA = $5,738. Your employer pays an identical $5,738 that never appears on your payslip.
Effective rate vs marginal rate
effective_rate = total_tax ÷ gross_income
- marginal rate
- The rate on your next dollar earned — the bracket you are "in"
- effective rate
- What you actually pay across all income. Always lower than the marginal rate
Worked example
$75,000 single: $7,670 federal + $5,738 FICA.
- Total federal-level tax: 7,670 + 5,738 = 13,408
- 13,408 ÷ 75,000 = 0.1788
Result: 17.9% effective, against a 22% marginal bracket. The gap is why "moving into a higher bracket" is not something to fear.
Federal Income Tax Brackets — Tax Year 2026
Applied to taxable income, i.e. after the standard deduction. Published by the IRS in Rev. Proc. 2025-32. These change every year; re-check before relying on them.
| Rate | Single filer | Married filing jointly |
|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 |
| 12% | $12,400 – $50,400 | $24,800 – $100,800 |
| 22% | $50,400 – $105,700 | $100,800 – $211,400 |
| 24% | $105,700 – $201,775 | $211,400 – $403,550 |
| 32% | $201,775 – $256,225 | $403,550 – $512,450 |
| 35% | $256,225 – $640,600 | $512,450 – $768,700 |
| 37% | Over $640,600 | Over $768,700 |

Payroll Tax Rates and Caps — 2026
| Tax | Rate (employee) | Wage cap | Employer pays |
|---|---|---|---|
| Social Security (OASDI) | 6.2% | $184,500 | Another 6.2% |
| Medicare (HI) | 1.45% | No cap | Another 1.45% |
| Additional Medicare | 0.9% | Above $200k single / $250k joint | Nothing — employee only |
What an Effective Rate Actually Looks Like
Single filer, standard deduction, no pre-tax contributions, federal taxes only — no state tax. Note how far the effective rate sits below the marginal bracket.
| Gross salary | Federal income tax | FICA | Effective rate | Marginal bracket |
|---|---|---|---|---|
| $50,000 | $3,820 | $3,825 | 15.3% | 12% |
| $75,000 | $7,670 | $5,738 | 17.9% | 22% |
| $100,000 | $13,170 | $7,650 | 20.8% | 22% |
| $150,000 | $24,734 | $11,475 | 24.1% | 24% |
| $250,000 | $51,304 | $15,514 | 26.7% | 32% |
States With No Broad Personal Income Tax
Nine states do not tax ordinary wage income. Several make it up through higher sales or property taxes, so "no income tax" is not the same as "low tax".
| State | Note |
|---|---|
| Alaska | No state income or state sales tax |
| Florida | |
| Nevada | |
| New Hampshire | Historically taxed interest and dividends only; that tax has been repealed |
| South Dakota | |
| Tennessee | |
| Texas | Among the highest property tax rates in the country |
| Washington | No wage tax, but does levy a capital gains tax |
| Wyoming |
How to Read Your Result
Withholding is not your tax bill
What comes out of each paycheck is an estimate your employer makes from the W-4 you filed. Your actual liability is settled when you file a return, and the difference is your refund or balance due. A large refund is not a win — it means you lent the government money interest-free all year. A large bill usually means the W-4 does not reflect your situation, commonly because of a second job or a working spouse.
Why your bonus looks over-taxed
Bonuses are supplemental wages, and employers commonly withhold federal tax on them at a flat 22% (rising to 37% on amounts above $1 million in a year), rather than at your normal rate. If your effective rate is 12%, a bonus appears to be taxed nearly twice as heavily. Nothing extra is actually owed — the over-withholding comes back as a larger refund. This is the most common "my paycheck is wrong" question, and it is not an error.
A raise cannot lower your take-home pay
Only the income above a bracket threshold is taxed at the higher rate. Crossing from the 12% band into the 22% band means the next dollar is taxed at 22%, not all of your income. The one real exception is benefit cliffs — subsidies and credits that phase out at a hard income line — which are a feature of those programs, not of the tax brackets.
Pre-tax contributions reduce income tax but not FICA
A traditional 401(k) contribution lowers your taxable income, so it reduces federal and state income tax immediately. It does not reduce Social Security or Medicare — those are calculated on gross wages. So a $1,000 contribution at a 22% marginal rate costs you about $780 of take-home pay, not $1,000.
Limitations & Accuracy Notes
- State tax is applied here as a single flat rate you enter. Most states with an income tax use progressive brackets and their own deductions, and some cities add a local income tax on top. For an accurate state figure, use your state revenue department or a payroll provider with per-state tables.
- The federal calculation assumes the standard deduction and a single job. It does not model itemized deductions, tax credits (child tax credit, EITC, education credits), the qualified business income deduction, or self-employment tax.
- Head of household and married filing separately are not offered as filing statuses here; only single and married filing jointly.
- Tax year 2026 figures are used throughout, from IRS Rev. Proc. 2025-32 and SSA. These are adjusted annually — if you are reading this in a later tax year, verify the numbers before relying on them.
- Self-employed people pay both halves of FICA as self-employment tax (12.4% Social Security plus 2.9% Medicare), with a partially offsetting deduction. This calculator models an employee, not a contractor.
- This is an estimate for planning, not tax advice or a substitute for filing. For anything consequential, use the IRS Tax Withholding Estimator or speak to a qualified tax professional.
