Refund = tax withheld + estimated payments + refundable credits − total tax. Total tax = income tax on taxable income (2026 brackets) − Child Tax Credit and credit for other dependents + self-employment tax + Additional Medicare Tax + net investment income tax. Taxable income = AGI − standard (or itemized) deduction − cash-gift deduction (if you don't itemize) − Schedule 1-A deductions − QBI deduction. Itemized deductions follow 2026 Schedule A: state and local taxes up to the $40,400 SALT cap (less 30% of income over $505,000), mortgage interest, and mortgage insurance premiums (phased out above $100,000 of AGI, $50,000 married filing separately), gifts over 0.5% of AGI, medical costs over 7.5% of AGI and your other deductions, cut by 2/37 in the 37% bracket; you get the larger of that and the standard deduction plus up to $1,000 ($2,000 joint) of cash gifts. Married filing separately and your spouse itemizes? You must itemize too: use the itemized deduction calculator. Qualified dividends and long-term gains are taxed at 0%, 15% or 20% on top of your other income, with the 3.8% net investment income tax above $200,000 ($250,000 joint, $125,000 married filing separately). Collectibles and real-estate depreciation gains use the IRS Schedule D Tax Worksheet, with 28% and 25% maximum rates. A net capital loss offsets up to $3,000 of other income ($1,500 married filing separately) and the rest carries forward. Taxable Social Security follows the IRS worksheet (married filing separately has a $0 base unless you lived apart all year). Married filing separately can get the EITC only if you lived apart from your spouse for the last 6 months with a qualifying child. The EITC is figured as the IRS EIC table does ($50 bands), counting children under 17 plus older children who still qualify, and is $0 if investment income (interest, dividends, gains and tax-exempt interest) is over $12,200. Not included: state tax, AMT, education and other credits. Paying for child care? The child and dependent care credit is separate from the Child Tax Credit: estimate it here. For how the Child Tax Credit is figured, step by step, see our Child Tax Credit calculator.
Calculation tax.return-2026 v3.1.0.
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.
(Withholding + estimated payments + refundable credits) − (income tax after credits + self-employment tax + Additional Medicare Tax + net investment income tax) = refund (positive) or amount owed (negative)
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.
| Household | Taxable income | Tax before credits | Child credits used | Refundable credits | Withheld | Result |
|---|---|---|---|---|---|---|
| Single, $60,000 salary | $43,900 | $5,020 | $0 | $0 | $5,020 | Refund $0 |
| Married, $50,000 wages, 2 children | $17,800 | $1,780 | $1,780 | $5,963 | $0 | Refund $5,963 |
| Head of household, $45,000, 1 child | $20,850 | $2,148 | $2,148 | $1,101 | $0 | Refund $1,101 |
| Single server, $48,000 incl. $15,000 tips | $16,900 | $1,780 | $0 | $0 | $3,580 | Refund $1,800 |
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.
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 $3,343. The refund is $5,963, all of it from refundable credits. This is why calculators that treat every credit as nonrefundable badly understate refunds for working families.
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 ($1,049) is partly phased out at this income. Withholding was $0, so the estimated refund is $1,101.
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.
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.
The credit stays at $2,200 per child under 17, with up to $1,700 refundable, and the refund estimate above includes it. The child needs a Social Security number and, since 2025, so do you (or one spouse on a joint return). For the phase-out, the refundable part and the 2027 amount, use our Child Tax Credit calculator.
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.
| Deduction | Limit | Phase-out starts (MAGI) | Key conditions |
|---|---|---|---|
| Qualified tips | $25,000 per return | $150,000 ($300,000 joint) | SSN valid for work; married couples must file jointly; self-employed capped at the business's net income |
| Overtime premium | $12,500 ($25,000 joint) | $150,000 ($300,000 joint) | Only the "half" of time-and-a-half; reduced $100 per $1,000 over the threshold |
| Seniors 65+ | $6,000 per person | $75,000 ($150,000 joint) | Reduced by 6% of MAGI over the threshold; married couples must file jointly |
| Car loan interest | $10,000 | $100,000 ($200,000 joint) | New U.S.-assembled personal vehicle, loan taken out after 2024; reduced $200 per $1,000 (or part) over the threshold; leases don't qualify |
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.
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. In the estimator, fill in the "Itemized deductions" section (state and local taxes, mortgage interest and insurance, medical costs) and your cash gifts: it applies these limits, the 0.5% charity floor and the 7.5% medical floor, and uses whichever is bigger, itemizing or the standard deduction plus your gifts. Not sure whether itemizing pays? Compare the standard deduction with itemizing, federally and for your state.
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.
| Rate | Single | Married filing jointly | Head of household |
|---|---|---|---|
| 10% | $0 – $12,400 | $0 – $24,800 | $0 – $17,700 |
| 12% | $12,400 – $50,400 | $24,800 – $100,800 | $17,700 – $67,450 |
| 22% | $50,400 – $105,700 | $100,800 – $211,400 | $67,450 – $105,700 |
| 24% | $105,700 – $201,775 | $211,400 – $403,550 | $105,700 – $201,750 |
| 32% | $201,775 – $256,225 | $403,550 – $512,450 | $201,750 – $256,200 |
| 35% | $256,225 – $640,600 | $512,450 – $768,700 | $256,200 – $640,600 |
| 37% | Over $640,600 | Over $768,700 | Over $640,600 |
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.
| Filing status | Standard deduction | Extra if 65+ or blind (each) |
|---|---|---|
| Single | $16,100 | $2,050 |
| Married filing jointly | $32,200 | $1,650 |
| Married filing separately | $16,100 | $1,650 |
| Head of household | $24,150 | $2,050 |
| Qualifying surviving spouse | $32,200 | $1,650 |
For the two tax years after the year your spouse died, you can file as a qualifying surviving spouse if you haven't remarried and your dependent son, daughter or stepchild (not a foster child) lived with you all year, apart from temporary absences, in a home you paid more than half the cost of keeping up. For a 2026 return, that means your spouse died in 2024 or 2025; in the year of death you can still file jointly if you didn't remarry that year. You get the joint brackets and the joint standard deduction, which usually beats head of household. It isn't a joint return, though: the Child Tax Credit and EITC phase-outs, the tips, overtime, senior and car-loan interest deductions, the $1,000 cash-gift deduction, the QBI threshold, the Additional Medicare Tax threshold ($200,000) and the taxable Social Security formula all use the single amounts. The refund, W-4, self-employment and quarterly calculators all handle it (IRS Publication 501).
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.
Two credits can be paid to you even if you owe no tax: the refundable part of the Child Tax Credit and the earned income tax credit, worth up to $664–$8,231 in 2026 depending on children. See the full EITC limits and eligibility rules in our EITC calculator. This refund estimate figures the EITC the way the IRS table does. It counts children under 17 plus the older children you enter who still qualify (under 19, full-time students under 24, or permanently disabled at any age, as long as they lived with you more than half the year), and gives no credit if investment income is over $12,200 or if, without a qualifying child, you (and your spouse) are 65 or older. It doesn't estimate the EITC for married filing separately.
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.
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.
It handles the most common federal return. It doesn't calculate:
Getting Social Security? Enter your benefits and the estimator works out the taxable part; the Social Security tax calculator shows it line by line, with your tax-torpedo rate and state tax.
The EITC is figured as the IRS table does, with the assumptions listed above. When something is outside the model, the calculator flags it rather than guessing.
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.
$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).
Yes: $2,200 per child under 17, with up to $1,700 refundable, phased out at higher incomes. The Child Tax Credit calculator shows each step.
Yes. It adds the earned income tax credit (up to $8,231 in 2026), and none if investment income is over $12,200. For the eligibility rules and your exact credit, use the EITC calculator.
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.
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.
The IRS hasn't announced it yet; it announces the date in January. The 2026 season opened January 26, 2026.
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.
