Whether you're considering a move to the United States or just want to understand your paycheck, this guide breaks down exactly how net salary is calculated in our salary comparison calculator.
In short: Your gross salary gets reduced by FICA taxes (7.65%), federal income tax (10%–37% progressive), and state income tax (0%–13.3% depending on your state). Filing status and children can save you thousands through the standard deduction and Child Tax Credit.
What factors have the biggest impact on your take-home pay?
The IRS considers many variables when calculating your exact withholding. But not all of them matter equally. Here are the factors that actually move the needle, ranked by impact:
1.
Gross annual salary
HIGH IMPACT
Determines which federal tax brackets you fall into. The difference between earning $50,000 and $100,000 can mean jumping from a ~15% effective rate to ~21% — that's roughly $5,500 more in taxes per year.
2.
State of residence
HIGH IMPACT
Nine states have no income tax at all (Texas, Florida, Nevada, etc.), while California's top rate reaches 13.3%. On a $100,000 salary, the difference between living in Texas vs. California is roughly $6,500/year.
3.
Filing status and dependents
HIGH IMPACT
Married Filing Jointly gets a $32,200 standard deduction vs. $16,100 for Single. Plus each child under 17 qualifies for a $2,200 Child Tax Credit. A married couple with 2 kids earning $80,000 takes home roughly $7,900/year more than a single filer with the same salary.
4.
Pre-tax retirement contributions (401k, IRA)
MEDIUM IMPACT
Contributing to a 401(k) reduces your taxable income dollar-for-dollar. Maxing out at $24,500/year in the 22% bracket saves you up to $5,390 in federal taxes — though your actual take-home is lower since the money goes to retirement.
5.
City/local taxes, deductions, credits
LOW IMPACT
Some cities add local income tax (New York City up to ~3.9%, some Ohio cities ~2%). And itemized deductions (mortgage interest, charitable giving, SALT up to $40,400) can help high earners, but the standard deduction covers most people.
Our calculator accounts for: gross salary, filing status (single/married), number of children, and your state — the factors with the highest impact. For federal tax, it uses the 2026 brackets and standard deduction based on IRS guidelines.
How the calculation works: step by step
1. FICA Taxes (Social Security + Medicare)
Every W-2 employee pays 7.65% of their gross salary in FICA taxes, split between Social Security and Medicare:
| Tax |
Rate |
Cap |
| Social Security | 6.2% | $184,500/year |
| Medicare | 1.45% | No cap |
| Additional Medicare (high earners) | +0.9% | Above $200,000 (single) |
| Total employee FICA |
7.65% |
|
Social Security cap: You only pay Social Security tax on the first $184,500 of earnings. If you earn more, the maximum Social Security tax is $11,439/year. Medicare has no cap.
2. Standard Deduction
Before calculating federal income tax, you subtract the standard deduction from your income. This is the amount the IRS considers non-taxable:
| Filing Status |
Standard Deduction (2026) |
| Single | $16,100 |
| Married Filing Jointly | $32,200 |
| Married Filing Separately | $16,100 |
| Head of Household | $24,150 |
3. Federal Income Tax Brackets (2026)
Federal income tax is progressive: each bracket of income is taxed at a different rate. You don't pay the top rate on your entire salary — only on the portion that falls within that bracket.
| Taxable Income (Single) |
Rate |
Taxable Income (Married Filing Jointly) |
| Up to $12,400 | 10% | Up to $24,800 |
| $12,400 – $50,400 | 12% | $24,800 – $100,800 |
| $50,400 – $105,700 | 22% | $100,800 – $211,400 |
| $105,700 – $201,775 | 24% | $211,400 – $403,550 |
| $201,775 – $256,225 | 32% | $403,550 – $512,450 |
| $256,225 – $640,600 | 35% | $512,450 – $768,700 |
| Over $640,600 | 37% | Over $768,700 |
4. Child Tax Credit
Each qualifying child under 17 gives you a $2,200 tax credit — this reduces your tax bill dollar-for-dollar, not just your taxable income. The credit phases out for single filers above $200,000 and married couples above $400,000.
5. State Income Tax
On top of federal taxes, most states levy their own income tax. The variation is enormous:
The state tax gap: On a $75,000 salary, a single filer in Texas pays $0 in state tax, while the same person in California pays roughly $3,920 and in New York about $3,895. That's the equivalent of one extra month of rent.

Step-by-step example: $75,000 gross (single, no kids, Texas)
Step 1 — Monthly gross salary
$75,000 / 12 = $6,250/month
Step 2 — FICA taxes
Social Security: $75,000 x 6.2% = $4,650/year
Medicare: $75,000 x 1.45% = $1,087.50/year
Total FICA: $5,737.50/year ($478.13/month)
Step 3 — Taxable income
$75,000 - $16,100 (standard deduction) = $58,900
Step 4 — Federal income tax on $58,900
| Bracket | Amount | Rate | Tax |
|---|
| $0 – $12,400 | $12,400 | 10% | $1,240.00 |
| $12,400 – $50,400 | $38,000 | 12% | $4,560.00 |
| $50,400 – $58,900 | $8,500 | 22% | $1,870.00 |
| Total federal income tax | $7,670.00 |
Step 5 — State income tax
Texas: $0 (no state income tax)
Take-home pay
$5,132.71/month
$75,000 - $5,737.50 (FICA) - $7,670 (federal) = $61,592.50/year | Effective rate: 17.9%

Note: These figures assume a single filer in a no-income-tax state (Texas/Florida) with standard deduction and no 401(k) contributions. Add 3-10% state tax in most other states.
Frequently asked questions
Are the calculator results exact?
They're a
close estimate. The calculator uses 2026 federal brackets, FICA rates, standard deductions, and state tax data for all 50 states + DC. Your actual withholding may vary slightly based on local taxes, pre-tax benefits, and payroll-specific adjustments. For the exact number, check your W-4 setup with the
IRS Tax Withholding Estimator.
Does it include state taxes?
Yes. Our calculator includes state income tax for all 50 states and DC: 9 no-tax states, 14 flat-rate states, and 25 progressive-bracket states. It uses state-specific standard deductions and bracket structures. The summary table above shows Texas (no state tax) as a baseline — select your actual state in the calculator for accurate results.
What's the difference between marginal and effective tax rate?
Your marginal rate is the rate on your last dollar of income (the highest bracket you reach). Your effective rate is the total tax divided by total income. For example, someone earning $75,000 has a 22% marginal rate but only pays ~17.9% effective. The effective rate is what actually matters for your budget.
Does it include the employer's share of FICA?
No. The calculator only shows employee-side deductions (6.2% Social Security + 1.45% Medicare = 7.65%). Your employer pays an equal 7.65% on top of your salary, but this doesn't appear on your paycheck and doesn't reduce your take-home pay.
What about 401(k) and other pre-tax deductions?
Traditional 401(k) contributions reduce your taxable income. The 2026 limit is $24,500 ($32,500 if you're 50+). Our calculator supports 401(k), IRA ($7,500 limit), and HSA ($4,400 individual / $8,750 family) contributions. Note: these reduce your tax but also reduce your take-home pay since the money goes to savings.
Standard deduction vs. itemized — which should I use?
The standard deduction ($16,100 single / $32,200 married) works for most people. You should itemize only if your total deductible expenses (mortgage interest, charitable giving, state & local taxes up to the $40,400 SALT cap) exceed the standard deduction. Roughly 87% of taxpayers take the standard deduction.
Does this work for self-employed / 1099 workers?
No. This calculator is for W-2 employees. Self-employed workers pay self-employment tax (15.3% FICA — both employee and employer shares), can deduct business expenses, and make quarterly estimated tax payments. The tax structure is fundamentally different.
What if I want to compare my US salary with another country?
That's exactly what our main tool does. Enter your current salary, pick your origin city, choose a destination city abroad, and the calculator compares taxes, cost of living, and real purchasing power between both locations.
