Tax Refund Calculator 2026

Quick answer: what decides your 2026 refund

A refund isn't a bonus from the IRS. It's the difference between what was taken out of your pay during 2026 (plus any estimated payments) and the tax you actually owe once the year is over, plus any refundable credits that are paid out even when you owe no tax. If more went in than you owe, you get the difference back. If less went in, you owe the difference by the filing deadline.

For a benchmark: in the 2026 filing season (2025 returns), the IRS reported an average refund of $3,276 through the week ending May 8, 2026, up 11.5% from $2,939 a year earlier. By that date the IRS had issued 99.1 million refunds for the season. An average hides a lot of spread: families getting refundable credits often receive far more, and many single workers with one job get back little or nothing, because their withholding was close to right all year.

The calculator above works through the same steps as Form 1040 for the 2026 tax year, using the 2026 brackets, standard deduction, the new Schedule 1-A deductions and the child and earned income credits.

How the refund estimator works

(Withholding + estimated payments + refundable credits) − (income tax after credits + self-employment tax + Additional Medicare Tax) = refund (positive) or amount owed (negative)

1. Income to AGI. Wages, net self-employment profit and other taxable income are added up. Half of any self-employment tax, self-employed health insurance and other adjustments you enter come off, giving adjusted gross income (AGI).
2. Deductions. The larger of the 2026 standard deduction ($16,100 single, $32,200 joint, $24,150 head of household, plus the age-65 add-on) or your itemized deductions. Then the new Schedule 1-A deductions for tips, overtime, seniors and car-loan interest, which you can take on top of either one. Self-employed filers below the income threshold also get the qualified business income (QBI) deduction.
3. Tax from the brackets. Taxable income runs through the 2026 brackets for your filing status.
4. Credits. The Child Tax Credit ($2,200 per child under 17) and the $500 credit for other dependents reduce the tax. If the child credit is bigger than your tax, up to $1,700 per child can come back as the refundable Additional Child Tax Credit (ACTC). The Earned Income Tax Credit (EITC) is fully refundable.
5. Compare with what you paid. Federal income tax withheld (W-2 box 2) and estimated payments are set against the total tax. Refundable credits are added to what you paid.

Worked examples for four households

Each example assumes a 2026 Form W-4 filled out normally (filing status, plus Step 3 for children), so withholding is what an employer's payroll system would take using IRS Publication 15-T. Every figure comes from the same code as the calculator.

Single, one job: close to zero

The single filer's withholding ($5,020) matches the tax owed ($5,020), so the refund is $0. That's the W-4 working as designed: for a single job with no extras, it aims to withhold your actual tax, not to build in a refund. If a single worker with one job gets a large refund, it usually comes from something payroll didn't know about: a credit, a deduction, or extra withholding they asked for.

Married with two children: refundable credits drive the refund

With $4,400 in Step 3 of the W-4, payroll withholds $0 of income tax. On the return, the couple's tax before credits is $1,780. The Child Tax Credit wipes that out ($1,780 used), and the unused part comes back as $2,620 of Additional Child Tax Credit. The EITC adds $3,348. The refund is $5,968, all of it from refundable credits. This is why calculators that treat every credit as nonrefundable badly understate refunds for working families.

Head of household with one child

A single parent earning $45,000 has $2,148 of tax before credits. The $2,200 child credit covers $2,148 of it and $52 comes back as ACTC. The EITC ($1,054) is partly phased out at this income. Withholding was $0, so the estimated refund is $1,106.

A server with tips: the new deduction becomes a refund

The server's employer withholds as if all $48,000 were taxable: $3,580. Without the tips deduction the tax would be $3,580 and the refund $0. With $15,000 of qualified tips deducted on Schedule 1-A, taxable income falls to $16,900, tax falls to $1,780, and the refund is $1,800. (Employers can reflect the deduction in each paycheck if the worker lists expected tips on the 2026 W-4 Deductions Worksheet; see the W-4 calculator.) The tips and overtime calculator works through the caps and phase-outs in detail.

What's new on 2026 returns (filed in 2027)

The 2025 tax law, Public Law 119-21 (called the "One, Big, Beautiful Bill" in earlier IRS releases and "Working Families Tax Cuts" on newer pages), changed several things that affect 2026 refunds.

Child Tax Credit: $2,200 per child

The credit is $2,200 per qualifying child under 17 for 2026, and up to $1,700 per child is refundable. The credit is now permanent and indexed to inflation, with increases rounded down to the next $100, which is why the 2026 figure stays at $2,200. The child needs a Social Security number, and so do you (or at least one spouse on a joint return). The credit phases out by $50 for each $1,000 of income above $200,000 ($400,000 joint).

Four new deductions on Schedule 1-A

Schedule 1-A is a new attachment to Form 1040. Its deductions apply for 2025 through 2028, and you can take them whether you itemize or not.

These deductions lower income tax only. Social Security and Medicare taxes still apply to tips and overtime. From tax year 2026, employers must report qualified overtime separately on the W-2, which should make the overtime figure easier to find.

Bigger SALT limit and a charity deduction without itemizing

If you itemize, the cap on state and local taxes (SALT) is $40,400 for 2026 ($20,200 married filing separately), reduced by 30% of MAGI over $505,000 but not below $10,000. If you take the standard deduction, from 2026 you can also deduct up to $1,000 ($2,000 joint) of cash gifts to charity. Enter itemized deductions in the estimator's "itemized deductions" field, and charity gifts in the "cash gifts to charity" field (it applies only when you take the standard deduction).

2026 tax brackets and standard deduction

Each rate applies only to the slice of taxable income inside its band. Moving into a higher bracket never reduces your take-home pay; only the dollars above the line are taxed at the higher rate.

Married filing separately uses the single bands, except that the 37% rate starts at $384,350. Rates and the larger standard deduction are permanent under the 2025 law.

For comparison, 2025 standard deductions were $15,750, $31,500 and $23,625 (single, joint, head of household). People 65 or older can claim the separate $6,000 senior deduction on Schedule 1-A as well.

Earned Income Tax Credit 2026

The EITC rises with earnings up to a maximum, stays flat, then phases out. Investment income must be $12,200 or less.

The calculator uses the statutory formula; the IRS tables work in $50 bands, so the official figure can differ by a few dollars. It assumes investment income of $12,200 or less and, for filers without children, age 25 to 64. It doesn't estimate EITC for married filing separately.

When will I get my refund?

• E-filed with direct deposit: the IRS says it issues most refunds in fewer than 21 days.
• Paper returns: six weeks or more.
• EITC or ACTC: refunds on returns claiming these credits are held until mid-February. In 2026, the IRS expected most of these early refunds to arrive by March 2, 2026.
• Tracking: "Where's My Refund?" shows a status 24 hours after you e-file, or about four weeks after you mail a paper return.

The IRS is phasing out paper refund checks, so set up direct deposit. The 2026 filing season opened on January 26, 2026; the IRS announces the opening date for the 2027 season in January. Under the IRS's April 15 rule, 2026 returns are due April 15, 2027. An extension (Form 4868) gives more time to file, but not more time to pay.

Why your refund changed from last year

• Your W-4 is out of date. A new job, a raise, a second job or a working spouse changes your tax far more than withholding expects unless you update the form. Two jobs that each withhold as if they were the only one usually under-withhold.
• New deductions payroll didn't know about. Tips, overtime, the senior deduction and car-loan interest lower your tax at filing time. If you didn't list them on the W-4 Deductions Worksheet, the saving shows up as a bigger refund, as in the server example above.
• Credits changed. A child turning 17 moves from the $2,200 child credit to the $500 other-dependent credit. Higher earnings can push the EITC into its phase-out.
• Side income. Freelance and gig profit has no withholding, and it also carries self-employment tax. See the self-employment tax calculator.
• Bonuses. Bonuses are often withheld at a flat 22%. If your top bracket is lower, part comes back at tax time; if higher, you may owe. The bonus tax calculator shows the difference.

A very large refund means you lent money to the government interest-free. If you'd rather have it in each paycheck, the W-4 calculator shows how to adjust, and the paycheck calculator shows the effect on take-home pay.

What this estimator doesn't cover

It handles the most common federal return. It doesn't calculate:

• state or local income tax;
• the special rates on long-term capital gains and qualified dividends (enter these as other income only as a rough guide);
• the alternative minimum tax (AMT);
• education credits and other credits not listed above;
• the QBI deduction for self-employed filers above the income threshold.

The EITC is a formula estimate with the assumptions listed above. When something is outside the model, the calculator flags it rather than guessing.

Common questions

What is the average tax refund?

In the 2026 filing season (2025 returns), the IRS reported an average refund of $3,276 through May 8, 2026, up 11.5% from $2,939 a year earlier.

What is the standard deduction for 2026?

$16,100 single or married filing separately, $32,200 married filing jointly and $24,150 head of household. Add $1,650 for each person 65 or older or blind ($2,050 if unmarried).

How much is the Child Tax Credit for 2026?

Up to $2,200 per qualifying child under 17, of which up to $1,700 is refundable as the Additional Child Tax Credit.

What is the maximum EITC for 2026?

$664, $4,427, $7,316, $8,231 for zero, one, two and three or more qualifying children. Investment income must be $12,200 or less.

Are tips and overtime tax-free on my 2026 return?

Not entirely. Up to $25,000 of qualified tips and up to $12,500 ($25,000 joint) of overtime premium can be deducted on Schedule 1-A, with phase-outs at higher incomes. Social Security and Medicare taxes still apply.

How long does a refund take?

Most e-filed refunds arrive in under 21 days; paper returns take six weeks or more. Returns claiming the EITC or ACTC are held until mid-February.

When does the 2027 tax season start?

The IRS hasn't announced it yet; it announces the date in January. The 2026 season opened January 26, 2026.

Why do I owe when I usually get a refund?

The most common reasons are a second job or working spouse, side income with no withholding, or a W-4 that hasn't been updated. Check your withholding now with the W-4 calculator so next year doesn't repeat it.
