Step-by-step solution

  1. With no other income or adjustments, your wages are your adjusted gross income (AGI)

    AGI=$62,000.00

  2. Start with the 2026 standard deduction for single filers

    standard deduction=$16,100.00

  3. Subtract your deductions to find taxable income, the part that's taxed. It can't go below zero

    $62,000.00−$16,100.00=$45,900.00

  4. Work out tax with the 2026 brackets. Each rate only applies to its own slice of income. Your top rate is 12%

    tax before credits=$5,260.00

  5. This is your 2026 federal income tax after credits

    tax=$5,260.00

  6. You paid more than your tax, so the difference should come back to you as a refund

    $6,000.00−$5,260.00=$740.00

Test yourself

20 quick questions built from this calculator's formula: work out results, predict what happens when an input changes, and work backward from an answer. Every answer comes with the working.

Please note: Results are estimates for planning and comparison. Lenders, banks, and tax authorities may round differently or include fees not modeled here, so confirm figures with your provider before deciding.

What this calculator does

Find out whether you'll get money back when you file your 2026 federal tax return, and about how much. Your refund is the gap between two numbers. One is the tax already taken out of your pay during the year. The other is the tax you actually owe once your deductions and credits are counted. If more was taken out than you owe, the IRS sends back the difference. If less was taken out, you pay the rest when you file.

The calculator uses the 2026 tax brackets, the 2026 standard deduction and the $2,200 child tax credit. It also handles the new 2026 deductions for tips, overtime pay and people 65 or older. Returns for 2026 are filed in early 2027. It covers federal income tax only, so state tax isn't included. Treat the result as an estimate for planning, not as tax advice.

Where it's used

Why this math matters outside the classroom:

  • Refund check. A couple with $6,440 of tax, a $4,400 child credit and $3,000 withheld subtracts to find a $960 refund.
  • Bracket slices. A single filer with $45,900 of taxable income pays 10% of $12,400 plus 12% of $33,500, which is $5,260.
  • Credit phase-out. At $210,500 of income, a single parent's $2,200 credit drops by 5% of $11,000, or $550, leaving $1,650.
  • Refundable credits. A parent earning $8,000 with no tax can get 15% of the $5,500 above $2,500, which is $825, as a refund.
  • Personal finance class. Students compare withholding with the actual tax to see that a refund is money paid in advance, not a gift.

How to use it

  1. Pick your filing status. Enter the wages from box 1 of your W-2 forms, plus any other taxable income.
  2. Choose the standard deduction or enter your itemized total. Add tips, overtime or people 65 and older if they apply.
  3. Enter your children under 17, other dependents and any other credits you expect.
  4. Enter the federal tax taken out of your pay (box 2 of your W-2) and any estimated payments. Read your refund or amount owed.

What the inputs mean

Wages, salary and tips for the year
Use box 1 of each W-2, not your salary. Box 1 already leaves out pre-tax 401(k) and most health plan payments, so it's the number the IRS taxes. On a joint return, add both spouses' forms.
Other taxable income (optional)
Interest, unemployment, taxable retirement withdrawals and similar income.
Adjustments to income (optional)
Amounts that come off your income before deductions, such as deductible IRA contributions, HSA contributions you made yourself and student loan interest. Don't repeat 401(k) money that's already left out of box 1.
Boxes checked for age 65+ or blind (optional)
One per person 65 or older and one per person who is blind: up to 2 each, or 4 on a joint return.
Cash gifts to charity (optional)
New for 2026, you can deduct cash gifts to charity even if you don't itemize. The limit is $1,000, or $2,000 on a joint return. The calculator adds the smaller of your gifts and that limit.
Total itemized deductions
Your Schedule A total. The standard vs. itemized calculator can work it out for you.
People on the return age 65 or older (optional)
The senior deduction is $6,000 for each person on the return who is 65 or older by the end of 2026. It shrinks by 6% of income over $75,000 ($150,000 joint). It's separate from the extra standard deduction for age.
Qualified tips (optional)
Tips count only if they come from a job on the IRS list of jobs that usually earn tips. The most you can deduct is $25,000. It shrinks by $100 for each full $1,000 of income over $150,000 ($300,000 joint).
Qualified overtime premium (optional)
Only the extra part of overtime pay counts. If your normal rate is $20 and overtime pays $30, the $10 extra per hour is the premium. The limit is $12,500, or $25,000 joint, with the same income cut as tips.
Children under 17 (optional)
Each child must be under 17 at the end of 2026 and have a Social Security number. The credit is $2,200 per child. It shrinks by $50 for each $1,000 of income over $200,000 ($400,000 joint).
Other dependents (optional)
Such as a child 17 or older, or a parent you support. Worth up to $500 each.
Other tax credits (optional)
Education, child care and other credits that can only cut your tax to zero.
Refundable credits (optional)
Some credits are paid to you even if you owe no tax at all. The earned income credit is the most common one. Enter its amount here if you expect to claim it.
Federal tax withheld and paid
Box 2 of your W-2s shows the federal income tax taken out. Add tax withheld on 1099 forms and any 2026 estimated payments. Don't include Social Security or Medicare tax.

Formula and method

AGI = wages + other income − adjustments
taxable income = max(0, AGI − deduction − tips, overtime and senior deductions)
tax = bracket tax − other credits − child credit (down to zero)
refundable child credit = smallest of: credit left over, $1,700 × children, 15% × (wages − $2,500)
refund = tax withheld + refundable credits − tax

AGI is your adjusted gross income: your total income after a few adjustments. Taxable income is what's left after your deductions. Bracket tax means each slice of taxable income is taxed at its own 2026 rate, from 10% to 37%. And max(0, …) means the result can't go below zero.

Credits work in two ways. Most credits can only cut your tax down to zero. Part of the child tax credit, up to $1,700 per child, is refundable. That means it's paid to you even when your tax is already zero. The refundable part is limited to 15% of your wages above $2,500.

A negative refund means you owe. The calculator shows that as the amount you owe instead of a negative number.

Worked example

A married couple filing jointly earns $90,000 in W-2 wages in 2026. They have two children under 17, take the standard deduction, and had $3,000 of federal tax withheld.

  1. Taxable income: $90,000 − $32,200 standard deduction = $57,800.
  2. Tax: 10% of the first $24,800 is $2,480, and 12% of the next $33,000 is $3,960. Together that's $6,440.
  3. Child tax credit: 2 × $2,200 = $4,400, which brings the tax down to $2,040.
  4. Refund: $3,000 withheld − $2,040 of tax = $960.

Result: Their estimated refund is $960.

Understanding the result

A refund isn't a bonus. It's your own money coming back, because more tax was taken out than you needed to pay. A big refund means you could have had more in each paycheck. The W-4 withholding calculator shows how to change that.

If you owe, the balance is due by the April 2027 filing deadline. Owing $1,000 or more can also bring an underpayment penalty, unless your withholding met one of the safe harbor rules. You can still raise your withholding for the rest of 2026 to close the gap.

Try different numbers to plan ahead. For example, see what happens to your refund if you add a child, give more to charity, or get a raise.

Assumptions and limitations

  • It uses the tax year 2026 brackets, standard deduction, child tax credit amounts and Schedule 1-A deduction rules published by the IRS.
  • All income is treated as ordinary income. Wages count as earned income for the refundable child credit. Your AGI stands in for the modified AGI used by the income limits.
  • The child credit income limits and the tips, overtime and senior deduction rules follow the 2026 IRS forms. Married couples filing separately can't take the tips, overtime or senior deductions.
  • This is an estimate, not tax advice. Your actual refund depends on your full return, so check it with tax software, the IRS instructions or a tax professional.
  • State and local income taxes aren't included. Neither are self-employment tax, lower rates on long-term capital gains, or the alternative minimum tax.
  • The earned income credit and most other credits aren't worked out for you. Enter them as dollar amounts. Some families with three or more children may get a slightly larger refundable child credit than shown.
  • It doesn't check whether your tips, overtime, children or dependents meet every IRS rule. It assumes they qualify.

Frequently asked questions

When will I get my 2026 tax refund?

Returns for 2026 are filed in early 2027. The IRS says to allow about 3 weeks after you file online, and 6 weeks or more for a mailed return. By law, refunds on returns that claim the earned income credit are held until mid-February.

Why is my refund smaller than last year?

Common reasons are a raise, a second job, or a change in your W-4. Losing a credit matters too, such as a child turning 17. Withholding may also have been lower all year. Compare the tax and the withholding lines separately to see which one changed.

Is the child tax credit $2,200 for 2026?

Yes. For 2026 the credit is up to $2,200 for each child under 17 with a Social Security number. Up to $1,700 of it per child can be refunded if your tax is already zero, as long as you have earned income over $2,500.

Do I need to itemize to deduct tips, overtime or the senior deduction?

No. These new deductions are taken whether you itemize or take the standard deduction. Each one has its own cap and shrinks at higher incomes. Married couples must file jointly to claim them.

Does a bigger refund mean I paid less tax?

Not by itself. Your tax depends on your income, deductions and credits. Your refund only shows how much extra was withheld along the way. Two people with the same tax can get very different refunds.
