2026 Federal Income Tax Calculator

This free 2026 tax calculator estimates how much federal income tax you will owe or get back as a refund for the 2026 tax year. It uses the latest IRS tax brackets, standard deduction amounts, and credit rules that apply to returns filed in 2027. Just enter your income, filing status, deductions, and credits, and the tool calculates your tax in real time.

How Federal Income Tax Works in 2026

The United States uses a progressive tax system. This means you pay a lower rate on the first dollars you earn and a higher rate as your income goes up. In 2026, there are seven federal tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.1 Your filing status, such as Single, Married Filing Jointly, or Head of Household, determines the income ranges for each bracket.

You do not pay tax on every dollar you make. First, you subtract your deductions from your adjusted gross income (AGI). Most people take the standard deduction, which is $16,100 for Single filers and $32,200 for Married Filing Jointly in 2026.1 If your mortgage interest, state taxes, and charitable gifts add up to more than the standard deduction, you may save money by itemizing instead. The amount left after your deduction is your taxable income, and that is what gets taxed.

Tax Credits vs. Tax Deductions

A deduction lowers the income that gets taxed. A tax credit cuts your tax bill dollar for dollar, so credits are usually worth more. Key 2026 credits include the Child Tax Credit ($2,200 per child under 17),5 the Earned Income Tax Credit (EITC) for lower-income workers, and education credits like the American Opportunity Credit.12 Some credits are refundable, which means they can give you money back even if you owe no tax.

Other Taxes This Calculator Covers

Beyond federal income tax, most workers also pay FICA payroll taxes: 6.2% for Social Security (up to $184,500 in wages) and 1.45% for Medicare.3 If you are self-employed, you pay both the employee and employer share, known as self-employment tax.4 This calculator also estimates your state income tax and any local or city tax so you can see your full tax picture in one place.

Key 2026 Tax Numbers to Know

Frequently asked questions

When do I file my 2026 tax return?

Your 2026 federal tax return is due by April 15, 2027. You can file an extension to push the deadline to October 15, 2027, but any tax you owe is still due by April 15. Individual returns are normally due April 15, and an automatic 6-month extension of time to file is not an extension of time to pay.15

What are the 2026 federal tax brackets?

There are seven brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%.1 The income ranges depend on your filing status. For example, a Single filer pays 10% on the first $12,400, then 12% up to $50,400, and so on.1 The calculator applies each bracket automatically.

What is the standard deduction for 2026?

The 2026 standard deduction is $16,100 for Single filers, $32,200 for Married Filing Jointly, $16,100 for Married Filing Separately, $24,150 for Head of Household, and $32,200 for Qualifying Surviving Spouse.1 If you are 65 or older, you get an extra amount on top.16 For 2026 that extra amount is $1,650, or $2,050 if you are unmarried and not a surviving spouse.2

How do I know if I should itemize or take the standard deduction?

Add up your mortgage interest, state and local taxes up to the SALT cap, charitable gifts, and medical costs above 7.5% of your AGI.8 If that total is more than your standard deduction, itemizing saves you money. This calculator shows both totals side by side and tells you which one is better.

What is the difference between a tax refund and a balance due?

A refund means you paid more in withholding and estimated payments than you owe, so the IRS sends money back to you. A balance due means you still owe money and need to pay the difference when you file.

What is the difference between marginal tax rate and effective tax rate?

Your marginal rate is the tax rate on the last dollar you earned. Your effective rate is the average rate across all your income, or total tax divided by total income. The effective rate is always lower than the marginal rate because of the progressive bracket system. You can toggle between both views in the results table.

How is Social Security income taxed?

The calculator uses your provisional income (other income plus half your Social Security) to figure out how much is taxable. Depending on your income level, none, up to 50%, or up to 85% of your Social Security benefits may be taxed.14 The tool does this math for you and shows the taxable amount.

What is the SALT cap for 2026?

The state and local tax (SALT) deduction is capped at $40,400 for 2026.17 This includes state income taxes, property taxes, and local taxes combined. If your total SALT exceeds this cap, only $40,400 counts toward your itemized deductions.

How much is the Child Tax Credit for 2026?

Each qualifying child under 17 is worth a $2,200 Child Tax Credit.5 Up to $1,700 of that is refundable as the Additional Child Tax Credit.5 The credit begins to phase out at $200,000 of AGI for Single filers and $400,000 for Married Filing Jointly.5

What is the Earned Income Tax Credit and do I qualify?

The EITC is a refundable credit for workers with low to moderate earned income. The amount depends on your income, filing status, and number of children. Investment income must be under $12,200.2 This calculator estimates your EITC automatically based on the data you enter.

Can I claim both the American Opportunity Credit and the Lifetime Learning Credit?

No. You can only claim one education credit per student.12 The AOTC is worth up to $2,500 and is partly refundable.12 The LLC is worth up to $2,000 and is not refundable.12 The calculator enforces this rule: checking one box unchecks the other.

What happens if I am claimed as a dependent on someone else's return?

Your standard deduction is limited. Instead of the full amount, it is capped at the greater of $1,350 or your earned income plus $450, but not more than the normal standard deduction.2 Select Yes under the dependent question and the calculator adjusts automatically.

What is the senior bonus deduction shown in the results?

For 2025 through 2028, taxpayers age 65 or older can get an extra $6,000 deduction per qualifying senior.6 This phases out for higher incomes. The deduction is reduced by 6 percent of the amount by which your modified adjusted gross income exceeds $75,000 (Single) or $150,000 (Married Filing Jointly).18 The calculator applies this automatically.

Why is my take-home pay different from my wages minus federal tax?

Take-home pay subtracts all taxes (federal income tax, FICA, self-employment tax, state tax, and local tax) plus your retirement contributions like 401(k) and IRA. That is why it is lower than just wages minus federal tax.

What if I do not have my W-2 yet?

Select No under the W-2 question. Then enter your gross pay per paycheck and how often you get paid. The calculator multiplies these to estimate your annual wages. You can update the numbers later when you get your W-2.

How much can I contribute to a 401(k) in 2026?

The 2026 employee contribution limit is $24,500.13 If you are age 50 or older, you can add a $8,000 catch-up contribution, for a total of $32,500.13 These contributions reduce your AGI and lower your federal tax.
