Tax Calculator

Estimate your federal income tax and understand what your bracket really means. Enter your annual income and filing status, and get your taxable income, the tax owed in each bracket, your marginal rate (the rate on your next dollar), your effective rate (what you actually pay overall), and your after-tax income.

How Progressive Tax Brackets Work

The most expensive misunderstanding in personal finance is the idea that “being in the 22% bracket” means you pay 22% of everything. You do not. The US uses a progressive, marginal system: income is sliced into bands, and each band is taxed at its own rate. Only the dollars inside the top band get the top rate.

Example: a single filer with $75,000 gross income and the $16,100 standard deduction has $58,900 of taxable income. Tax is 10% on the first $12,400 ($1,240), 12% on the next $38,000 ($4,560), and 22% only on the remaining $8,500 ($1,870) — total $7,670. The marginal rate is 22%, but the effective rate is just 10.2% of gross income. That gap is why the two numbers are both shown above.

A raise can never reduce your take-home pay: only the new dollars are taxed at the higher rate, and you keep the rest. Turning down a raise over bracket fears is always a mistake.

How to Use This Tax Calculator: Step by Step

This calculator answers one question well — what simplified 2026 US federal income tax looks like on a given income — and it is important to use it inside that scope. State tax, FICA, and credits are excluded, so treat every result as a bracket illustration, not a filing figure.

1. Enter your annual gross income. Use total income before any deductions: salary, plus freelance income, bonuses, and other taxable income you expect for the year. For the gross figure behind this, the salary calculator converts any pay schedule into an annual total.
2. Choose your filing status. Single and married-filing-jointly use different brackets and different standard deductions, and the difference is large — the worked example below shows $4,530 on the same $90,000. Choose the status you actually file under.
3. Check the deduction field. It is prefilled with the 2026 standard deduction for your status ($16,100 single, $32,200 joint). If you itemize, replace it with your itemized total to compare the two — the larger deduction wins.
4. Read all three rates. The marginal rate governs decisions about the next dollar; the effective rate on gross income is your overall burden; the effective rate on taxable income sits between them. Confusing the three is the most common tax error.
5. Read the “room before the next bracket” line. It tells you how much more income you can earn before the marginal rate rises — useful when timing a bonus or freelance payment.

Re-run the calculation at a higher and lower income to see how the result moves. Because only the top slice of income is taxed at the top rate, the tax rises much more slowly than income does — which is exactly why raises always increase take-home pay.

2026 US Federal Brackets (Single Filers)

Married-filing-jointly thresholds are roughly double, with a $32,200 standard deduction. Brackets are adjusted for inflation each year. The Internal Revenue Service publishes the official figures, and the Social Security Administration covers the FICA side (Social Security and Medicare taxes, which this calculator excludes).

Marginal Rate vs Effective Rate — When Each Matters

• Use the marginal rate for decisions about the next dollar: a raise, a bonus, extra freelance income, or a deduction. A $1,000 deduction saves you $220 if your marginal rate is 22%, but only $120 at 12%.
• Use the effective rate to understand your overall burden: total tax divided by total income. It is the honest answer to “how much of my pay goes to tax?”
• Deductions work at the marginal rate. That is why retirement contributions and mortgage interest are worth more to higher earners.
• Credits beat deductions. A $1,000 credit cuts tax by $1,000 regardless of bracket; a $1,000 deduction cuts it only by your marginal rate.

What This Calculator Does Not Include

• State and local income tax — varies widely, from 0% to over 10%.
• FICA taxes — Social Security (6.2% up to the annual wage base) and Medicare (1.45% on all wages, plus 0.9% over $200,000 for single filers).
• Credits — child tax credit, education credits, and others reduce tax dollar-for-dollar.
• Capital gains and other income types — taxed under different rules.

Worked Example: Two Filers, Same Income, Different Tax

Take $90,000 of gross income. A single filer using the $16,100 standard deduction has $73,900 of taxable income. The tax is 10% on the first $12,400 ($1,240), 12% on the next $38,000 ($4,560), and 22% only on the remaining $23,500 ($5,170) — a total of $10,970, an effective rate of about 12.2% on gross income.

A married couple filing jointly on the same $90,000, using the $32,200 standard deduction, has $57,800 of taxable income. Their joint thresholds are roughly double: 10% on the first $24,800 ($2,480) and 12% on the remaining $33,000 ($3,960) — a total of $6,440, an effective rate of about 7.2% on gross income. Same income, $4,530 less tax, purely from filing status and the larger standard deduction. This is why the calculator asks for filing status before anything else: it changes the answer more than any other single input.

Remember: this comparison uses simplified 2026 US federal figures only, excluding state tax, FICA, and credits.

Remember the framing of this page: these are simplified 2026 US federal figures used as an example. State tax, FICA, and credits are excluded, so a real return will differ — use the result to understand brackets, not to file.

Deductions vs Credits: A Dollar Comparison

A $2,000 deduction and a $2,000 credit sound alike and are worth very different amounts. At a 22% marginal rate, a $2,000 deduction saves 2,000 × 0.22 = $440. A $2,000 credit saves the full $2,000, because credits subtract from tax itself rather than from taxable income. This is why tax planning chases credits first and deductions second.

Retirement contributions show deductions at their best. Putting $5,000 into a traditional 401(k) at a 22% marginal rate saves $1,100 of tax this year, and the money grows tax-deferred until withdrawal. At a 12% marginal rate the same contribution saves only $600 — still worthwhile, but the benefit scales with your bracket, which is why higher earners gain more from identical contributions.

Common Tax Planning Moves (Within This Example’s Scope)

• Time a bonus or freelance payment. Income landing in January instead of December is taxed a year later, and if next year’s income is lower, possibly at a lower marginal rate.
• Bunch itemized deductions. If mortgage interest, state taxes, and charitable gifts together are near the standard deduction, concentrating two years of gifts into one year can push you over it in that year.
• Fill lower brackets with retirement conversions. Converting part of a traditional retirement account to a Roth in a low-income year taxes that money at 10% or 12% instead of 22% later.
• Do not over-withhold on purpose. A big refund is an interest-free loan to the government. Adjusting withholding to match the estimate keeps the money in your paycheck all year.

These are general education ideas, not personal advice, and they interact with credits, state tax, and other rules this simplified federal example does not model. For decisions with real money, check the result against the salary calculator for gross pay and confirm details with a tax professional.

Why Two People With the Same Salary Pay Different Tax

Two single filers each earning $90,000 can owe visibly different federal tax, and the reasons are all inside the rules this simplified example models or names. One contributes $5,000 to a traditional retirement plan, cutting taxable income by $5,000 and saving $1,100 at a 22% marginal rate. The other takes the standard deduction with no adjustments. Same salary, $1,100 apart, before any credits enter the picture.

Filing status is the bigger lever, as the worked example above shows, and deductions versus credits decide the rest. What does not change the federal calculation in this example: state tax, which is a separate bill entirely, and FICA, which applies to wages regardless of deductions. That separation is exactly why a paycheck can look heavily taxed while the federal income tax line stays modest — several different taxes stack on the same pay, and only one of them follows the bracket table.

One more practical note: because this page models simplified 2026 US federal figures only, treat any comparison it produces as a way to understand the mechanics. A real return adds state tax, payroll taxes, credits, and income types taxed under different rules, and those can move the final number by thousands in either direction.

2026 Federal Brackets: Married Filing Jointly

The joint brackets mirror the single brackets at roughly double the thresholds, with a $32,200 standard deduction. This table is drawn from the same simplified 2026 federal figures the calculator uses, and carries the same exclusions: no state tax, no FICA, no credits.

Joint thresholds are not exactly double the single thresholds at every band — the top bands diverge — so do not estimate joint tax by simply halving single tax or doubling single thresholds. Use the calculator with the joint status selected, which applies the correct joint figures. Remember that this is still the simplified federal example only; a real joint return adds state tax, payroll taxes, and any credits the household qualifies for.

Worked Example: A $50,000 Income, Step by Step

Smaller incomes show the bracket mechanics just as clearly as large ones. Take a single filer earning $50,000 gross, using the $16,100 standard deduction.

Two things stand out. First, the marginal rate is 12% — only the dollars above $12,400 are taxed at 12%, and none reach the 22% band. Second, the effective rate is just 7.6% of gross income, far below either bracket rate, because the standard deduction removes $16,100 from taxation entirely and the first slice is taxed at only 10%. A filer at this income who believes they “pay 22% tax” is overestimating their burden by nearly three times. And the same framing caveat applies: this is the simplified federal example, excluding state tax, FICA, and credits — the real paycheck will show more total tax, from different taxes stacked together.

Standard Deduction vs Itemizing: How to Decide

Every filer gets a choice: take the standard deduction (a fixed amount, no questions asked) or itemize (add up specific deductible expenses and use the total if it is larger). The calculator’s deduction field lets you test either — enter your itemized total and compare the tax with the standard figure.

• Take the standard deduction when your itemizable expenses are below $16,100 (single) or $32,200 (joint). This is the case for most filers, because the standard amounts are generous.
• Itemize when mortgage interest, state and local taxes, charitable gifts, and medical expenses above the threshold together exceed the standard amount. Homeowners with large mortgages are the most common itemizers.
• Charitable bunching works. If gifts in a normal year fall just short, concentrating two years of giving into one year can push that year over the standard deduction, while the other year uses the standard amount — two deductions instead of one near-miss.
• Keep records for itemized claims. The standard deduction needs no documentation; itemized deductions need receipts, statements, and proof for every dollar claimed.
• State rules differ. Some states require the same choice as the federal return, others let you choose independently. The federal decision and the state decision are separate questions.

The saving from itemizing is only the excess over the standard deduction, taxed at your marginal rate — not the whole itemized total. At a 22% marginal rate, $4,900 of excess deductions saves $1,078. That is the correct way to value the decision, and it is why small excesses are barely worth the paperwork.

Marginal Rates at Different Incomes

The bracket table can feel abstract until it is tied to incomes people recognise. For a single filer using the standard deduction, the marginal rate — the rate on the next dollar — at various gross incomes in this simplified example is:

Notice how the marginal rate rises in steps while the effective rate rises smoothly. That step pattern is why the “room before the next bracket” line in the calculator is useful: income timed just below a threshold is taxed more lightly than the same income just above it, and the difference is the full step, not a gradual change.

How Withholding Works

Withholding is your employer estimating your annual tax, one paycheck at a time. Each paycheck is annualised — treated as if every paycheck all year were identical — and tax is withheld as if that annualised figure were your real income. The system works well for steady single-job earners and poorly for everyone else.

1. Your employer uses your W-4 settings. The form’s adjustments for multiple jobs, dependents, and extra withholding steer the estimate. Outdated W-4 settings are the most common cause of large refunds or surprise bills.
2. Bonuses are withheld differently. Supplemental wages like bonuses are usually withheld at a flat 22% federal rate, regardless of your bracket — which over-withholds for lower earners and under-withholds for higher ones, settling only at filing time.
3. Multiple jobs break the estimate. Each employer annualises independently, so two jobs each withholding as if they were your only income usually under-withhold in total. The W-4 multiple-jobs adjustment exists for exactly this case.
4. Mid-year changes distort the annualisation. A raise in July makes early paychecks look under-withheld and later ones look over-withheld; the return, not any single paycheck, settles the true figure.
5. Adjust withholding after big life events. Marriage, a new child, a second job, or a large freelance side income all change the correct withholding. A fresh W-4 after each event keeps the estimate honest.

A refund is not a bonus — it is your own money returned months late, interest-free. The calculator’s estimate is the right target for withholding: adjust the W-4 until each paycheck’s withholding annualises to roughly the calculator’s figure, and the refund shrinks toward zero while monthly cash flow rises.

Tax-Efficient Saving, in Plain Terms

Within this example’s federal scope, the most powerful legal tax reduction available to most workers is retirement saving, because it attacks the calculation at the most valuable point: taxable income, at the marginal rate.

• Traditional retirement contributions reduce taxable income now. A $5,000 contribution at a 22% marginal rate saves $1,100 this year; at 12%, the same contribution saves $600. The benefit scales with the bracket, which is why higher earners gain more from identical contributions.
• Roth contributions reverse the timing. Tax is paid now at the current marginal rate, and withdrawals in retirement are generally tax-free. Roth saving wins when today’s rate is lower than the expected retirement rate — typically early in a career.
• Employer matching beats both. A 50% or 100% match on contributions is an instant, guaranteed return no tax strategy can match. Always contribute at least enough to capture the full match before optimising anything else.
• Health savings accounts are triple-advantaged. Where eligible, contributions are deductible, growth is untaxed, and withdrawals for medical costs are untaxed — the only account with all three benefits, within its eligibility rules.
• Timing matters for conversions. In a low-income year — a sabbatical, a gap between jobs, early retirement — converting traditional savings to Roth taxes the money at 10% or 12% instead of 22% or more later. The calculator’s bracket table shows exactly how much room exists in the lower bands.

These are general education points about how the federal mechanics work, not personal advice, and they interact with credits, state tax, and other rules this simplified example does not model. For the growth side of the same decision, the compound interest calculator shows what tax-deferred growth becomes over decades.

Common Mistakes That Cost Real Money

1. Fearing the next bracket. A raise never reduces take-home pay. Only the dollars above each threshold face the higher rate, so every raise increases what you keep.
2. Confusing marginal and effective rates. Quoting the 22% marginal rate as “my tax rate” overstates the burden and distorts every decision built on it — including whether a deduction is worthwhile.
3. Ignoring FICA in paycheck math. This calculator excludes Social Security and Medicare, which together take 7.65% of most wages up to the Social Security wage base. A paycheck showing far more tax than this calculator estimates is usually showing FICA, not an error.
4. Forgetting state tax entirely. State income tax ranges from zero to over 10% depending on where you live, and it is a separate bill with separate rules. A federal-only estimate is never the whole picture.
5. Letting withholding drift for years. A W-4 from five years ago reflects a life that no longer exists. Review it after every major change, or accept a refund that is really an interest-free loan.
6. Missing credits by not filing. Some credits are refundable — they pay out even when no tax is owed — but only if a return is filed. Low earners who skip filing can leave real money unclaimed.

Frequently Asked Questions

Will a raise push all my income into a higher bracket?

No. Only the income above each threshold is taxed at the higher rate. Your earlier dollars keep their lower rates, so a raise always increases take-home pay.

What is the difference between marginal and effective rate?

Marginal rate is the tax on your next dollar (your top bracket). Effective rate is total tax divided by income — always lower, because your first dollars are taxed at 10% and 12%.

Should I use the standard deduction or itemize?

Use whichever is larger. About 90% of US filers take the standard deduction. Itemizing wins if mortgage interest, state taxes, and charitable gifts together exceed it — enter your itemized total in the deduction field to compare.

Does this include Social Security and Medicare?

No. FICA taxes are separate from income tax and apply to most wages. Add roughly 7.65% (up to the Social Security wage base) for a fuller picture of payroll deductions.

Do tax brackets change every year?

Yes, thresholds are inflation-adjusted annually, and Congress occasionally changes rates. Always check the current year’s figures before relying on an estimate.

What is taxable income?

Taxable income is gross income minus deductions — the standard deduction or your itemized total, plus adjustments like retirement contributions. Only taxable income passes through the brackets; your gross income never gets taxed at a single flat rate in this system.

Why does my paycheck withholding differ from this estimate?

Withholding is an estimate your employer makes from each paycheck, annualised as if every paycheck were identical. Bonuses, uneven hours, multiple jobs, and mid-year changes all make it diverge from the annual calculation, which is why the final return — not any single paycheck — settles the real figure.

Do I pay tax on a bonus at a higher rate?

Not in the annual calculation. A bonus is ordinary income taxed through the same brackets as salary — only the dollars above each threshold face the higher rate. The confusion comes from withholding: bonuses are usually withheld at a flat 22% federal rate, which can look like a special “bonus tax”. The return reconciles the difference, and any over-withholding comes back as a refund.

What if I have two jobs?

Your total income from both jobs passes through the brackets once, combined — but each employer withholds as if its job were your only income, which usually under-withholds in total. Use the multiple-jobs adjustment on the W-4, or add extra withholding, and run the combined income through this calculator to see the true annual figure. The surprise bill at filing time is one of the most common tax shocks, and it is entirely preventable.

Does this calculator handle self-employment tax?

No. Self-employed workers pay both the employee and employer shares of Social Security and Medicare, plus income tax, and usually owe quarterly estimated payments. This page models simplified 2026 US federal income tax only, excluding FICA and self-employment tax entirely. Self-employed filers should treat this result as one component of a larger bill and consult a tax professional or dedicated self-employment tools for the rest.
