Calculate your tax reality
You’ll see your after-tax income, keep-rate, total tax drag, main tax driver, and whether your withholding looks short or high.
Your tax pressure is moderate.
Your income is still giving you usable monthly take-home, but the tax layers are large enough that budgeting from gross salary would be misleading.
This is your estimated keep-rate after federal income tax, state/local estimate, Social Security, and Medicare.
Estimated income left after all selected tax layers.
Better budget baseline than gross monthly salary.
Federal, state/local, FICA, and self-employment tax if selected.
Share of gross income going to estimated taxes.
What this result really means
Your real spending power is the after-tax number, not the salary number.
Biggest risk
The biggest risk is using gross income for rent, car, or debt decisions.
Where your gross income goes
The table separates taxable income, federal tax, FICA, state/local estimates, withholding gap, and the final after-tax number.

How to use this US income tax calculator
Start with the income that actually gets taxed
Enter your annual W-2 wages first, then add other taxable income only if it should be included in your yearly tax picture. A bonus, taxable interest, or side income can change the result quickly because it may stack on top of your regular salary.
Choose the right filing profile
Filing status changes the standard deduction and bracket width. A single filer and a married couple can have the same household income but very different federal taxable income.
Use state tax as a planning estimate
Select a state estimate or use a custom rate. State tax rules are too different to treat this as a filing result, but the estimate is useful when comparing jobs, raises, relocation, or monthly budget pressure.
Check withholding separately
Withholding does not change your real tax. It only changes whether you may owe money or receive a refund when you file. A large refund usually means too much was withheld during the year.
What your result actually means
The most important number is not your gross salary. It is your after-tax income: the money left after federal income tax, state/local estimate, Social Security, Medicare, and any self-employment tax estimate you chose to include.
Your effective tax rate shows the share of total gross income going to taxes. This is different from your marginal tax rate. Your marginal rate only applies to the next layer of taxable income; your effective rate is the blended result after deductions and brackets.
The keep-rate is often the easiest way to understand the result. If the calculator says you keep 72¢ of every $1, that means about 28¢ is being absorbed by the selected tax layers before your budget even starts.
How to make a decision from the result
If take-home is lower than expected
Look first at FICA and state tax. Many people focus only on federal brackets, then get surprised because payroll tax and state tax are still taking money before the paycheck arrives.
If the withholding gap is negative
A negative gap means the estimate says you may not be paying enough through withholding or estimated tax. That does not prove you will owe, but it is a warning to check your W-4, bonus withholding, or side-income plan.
If a raise looks disappointing
Compare the extra take-home, not the extra gross salary. A $10,000 raise may feel smaller after federal, state, and payroll taxes, especially if it lands in a higher marginal bracket.
If you are comparing states
A lower-tax state can improve take-home pay, but it is not the full answer. Housing, insurance, commuting, property tax, and local costs may outweigh the tax difference.
After you know your take-home number, compare it with your budget using the 50/30/20 Budget Calculator USA, or test housing pressure with the Mortgage Affordability Calculator USA. If the real question is how much of that take-home pay can safely become savings, test the monthly target with the Simple Savings Calculator USA.
Real scenarios where this estimate matters
The raise that feels smaller than promised
Someone gets a $7,000 raise and expects roughly $583 more per month. The actual increase may be much lower after federal tax, Social Security, Medicare, and state tax. The calculator helps translate gross raise into real monthly spending power.
The side income tax shock
A worker earns extra money from freelancing or a second job and spends it like take-home income. Later, they discover that income tax and possibly self-employment tax were not fully covered. Before using that income for spending, debt payoff, or savings, check the tax reserve for side hustle income so the gross amount is not mistaken for spendable cash.
The relocation offer
A higher salary in a high-tax state can look better on paper but not improve monthly take-home as much as expected. The state estimate is not a full relocation calculator, but it gives a useful first check.
The large refund misunderstanding
A large refund can feel like a win, but it often means paychecks were smaller all year. Some households prefer that forced savings effect; others need the monthly cash flow more than a spring refund.
Common mistakes that make tax estimates misleading
Using gross salary as budget money
Gross income is not what pays rent, groceries, loans, or savings. Use monthly after-tax income for real budgeting decisions.
Confusing marginal and effective tax rates
Being in a 24% bracket does not mean every dollar is taxed at 24%. The US federal system uses progressive bracket layers.
Forgetting FICA
Social Security and Medicare can be a major tax layer even when federal income tax seems manageable. High earners also need to watch the Social Security wage base and Additional Medicare Tax.
Treating a refund as tax savings
A refund usually means your withholding exceeded your tax. It does not mean your total tax bill was lower.
Entering deductions as credits
Deductions reduce taxable income. Credits reduce tax after it is calculated. Mixing them up can seriously distort the estimate.
Ignoring state and local tax
State and local tax can change the real value of a raise, relocation, or second job. Even a simple estimate is better than pretending it is zero.
How the calculation works
The calculator starts with annual wages, other taxable income, and optional self-employment income. It then subtracts selected pre-tax or above-the-line planning adjustments such as traditional 401(k), HSA, and other deductions. For federal income tax, it compares the standard deduction with any itemized deduction override you enter and uses the larger amount.
Federal taxable income is then passed through progressive tax brackets for the selected year and filing status. Tax credits are subtracted after the bracket calculation. This matters because a $1,000 credit usually cuts tax more directly than a $1,000 deduction.
Social Security and Medicare are calculated separately when FICA is enabled. Social Security is limited by the annual wage base.Medicare does not use that wage base limit. When self-employment income is entered, the estimate also checks how W-2 wages and net self-employment earnings interact with the Social Security wage base and the Additional Medicare Tax threshold.
State and local tax are simplified planning estimates. A selected state applies a rough effective rate, while custom state and local rates let you enter your own estimate. This is useful for planning, but it does not replace official state tax software or a tax professional.
Withholding is compared against estimated federal and state tax. If withholding is higher than estimated tax, the calculator shows a possible overpayment/refund-style gap. If withholding is lower, it shows a possible amount still due. This is not an official refund calculation because real filing results depend on final forms, credits, deductions, dependents, and other details.
Income Tax Calculator USA 2026: estimate federal tax, state tax, FICA, and take-home pay
A US income tax estimate should answer more than “how much tax do I pay?” The better question is how much of your income remains available after federal tax, state or local tax, Social Security, Medicare, and selected deductions or credits. That after-tax number is the one that affects rent, mortgage affordability, savings, debt payoff, and day-to-day spending.
This calculator uses a decision-first structure because tax results are easy to misread. A person may see a high gross salary and assume the budget is safe, even though the monthly take-home number is much tighter. Another person may focus on a tax refund without realizing that the refund simply means more money was withheld from paychecks during the year.
The federal side uses progressive tax brackets, so not every dollar is taxed at the same rate. Deductions reduce taxable income before tax is calculated, while credits reduce tax after the bracket calculation. Payroll taxes are separate: Social Security and Medicare can still apply even when deductions reduce federal taxable income.
State tax is included as a planning estimate because it can materially change take-home pay. A job offer, raise, relocation, bonus, or side-income decision can look very different once state tax and FICA are included. For detailed filing, use official tax software or a qualified tax professional. For planning, this page gives a fast view of the tax pressure, the likely monthly take-home amount, and the areas worth checking next.
Income tax calculator FAQ
Yes, if the FICA option is enabled. Social Security is estimated up to the annual wage base, while Medicare is estimated without that wage base cap. Additional Medicare Tax can also be included in advanced assumptions.
No. It is a planning estimate. It compares your estimated tax with the withholding numbers you enter, but official filing results depend on final tax forms, credits, deductions, dependents, and IRS/state rules.
Marginal rate is the rate applied to your next layer of taxable income. Effective tax rate is your total estimated tax divided by gross income. For budgeting, effective rate and take-home pay are usually more useful.
In many W-2 situations, traditional 401(k) contributions reduce federal taxable income but do not reduce Social Security and Medicare wages. This calculator treats 401(k) that way for the main W-2 estimate.
Gross salary does not account for federal tax, payroll tax, state tax, local tax, and pre-tax deductions. Monthly take-home is the better planning number for real spending.
The calculator uses the standard deduction unless your itemized deduction override is higher. In real filing, itemizing depends on mortgage interest, state and local tax limits, charitable gifts, medical deductions, and other rules.
It can help with a first-pass comparison by showing how state tax changes take-home pay. It does not include housing, insurance, commuting, property tax, or local cost-of-living differences.
A refund usually means your withholding was higher than your final tax. It may feel positive, but it also means your paychecks were smaller during the year.
