Your refund amount appears on line 33 of Form 1040, labeled "Amount You Overpaid"

Line 33 is where the IRS shows how much federal income tax you overpaid during the year. This is the number that becomes your refund — the money the government sends back to you. If you filed a 1040-SR (for people 65 and older), the refund amount is also on line 33 in the same position.

The line sits near the bottom of the form, after all your income, deductions, and tax calculations are complete. The IRS calculates this number by subtracting what you owe in taxes from what you already paid through withholding or estimated tax payments. If that subtraction results in a positive number, that positive number is your refund.

You will see three related lines near line 33: line 31 shows your total tax, line 32 shows your total payments, and line 33 shows the difference. If line 33 is blank or zero, you do not have a refund — you either owe money or broke even.

Key Takeaways

  • Line 33 of Form 1040 displays your refund amount, labeled "Amount You Overpaid."
  • The refund is calculated by subtracting your total tax owed from your total payments made during the year.
  • If line 33 is blank or shows zero, you have no refund and either owe money or owe nothing.
  • The same line number and position appears on Form 1040-SR for taxpayers 65 and older.
  • Your refund amount on line 33 is the same figure the IRS uses to determine how much to send you back.

How the IRS calculates the number on line 33

The IRS works backward from your tax liability. First, they add up all your income from wages, investments, self-employment, and other sources. Then they subtract your deductions — either the standard deduction or your itemized deductions. That gives them your taxable income.

Next, they calculate how much federal income tax you owe on that taxable income using the tax tables for your filing status and income level. This is your total tax, which appears on line 31. Then they look at how much you already paid: money withheld from your paychecks (shown on your W-2 forms), estimated tax payments you made, and any other payments or credits.

Line 33 is simply the result of subtracting line 31 (what you owe) from line 32 (what you paid). If you paid more than you owed, the difference is your refund. If you paid less, line 33 will be blank and you will see an amount you owe instead, on a different line.

What happens after line 33 — refund delivery options

Once the IRS accepts your return and confirms the refund amount on line 33, they process the refund according to your instructions. On Form 1040, you choose how to receive your money: direct deposit to a bank account, a paper check mailed to your address, or a debit card (in some cases).

Direct deposit is the fastest method. The IRS typically sends refunds by direct deposit within 21 days of accepting your return, though many arrive sooner. A paper check takes longer — usually three to four weeks after acceptance, sometimes longer depending on mail delivery in your area.

The amount that leaves the IRS is exactly what line 33 shows. If you owe a debt to a federal or state agency, or if you owe back child support, the IRS may intercept part or all of your refund before it reaches you. In that case, you will receive a notice explaining the offset, and line 33 will not match what you actually receive.

Reading line 33 on different versions of Form 1040

The standard Form 1040 has been redesigned several times in recent years. In 2023 and 2024 returns, line 33 remains in the same position and carries the same label. If you are looking at a return from 2022 or earlier, the line numbers may differ slightly — in 2022, the refund line was also 33, but in 2021 and before, it was line 34.

If you filed using Form 1040-A or 1040-EZ in years when those forms were still available (through 2017), the refund line was in a different position. The IRS consolidated these forms into a single 1040 starting in 2018, so most recent returns use the current numbering.

When you receive a copy of your accepted return from the IRS — either printed or in your online account — line 33 will show the exact refund amount the IRS processed. This is the official record of your refund, and it matches what the IRS sends to your bank or mails to you.

Checking your refund status using line 33

The IRS provides a tool called "Where's My Refund?" on their website at irs.gov. You can enter your Social Security number, filing status, and the refund amount from line 33 to track your refund in real time. The tool will tell you whether the IRS has accepted your return, is processing it, or has sent your refund.

You must use the exact amount from line 33 to search. If you enter a different number, the tool will not recognize your return. This is why it matters to know where to find that line — it is the key to tracking your money.

The IRS updates "Where's My Refund?" once per day, usually overnight. If you just filed, the tool may not show your return for 24 hours. After that, you can check as often as you want, though the status will not change more than once per day.

What to do if line 33 is blank or shows zero

A blank line 33 means you have no refund. This happens when your total tax (line 31) equals or exceeds your total payments (line 32). You either owe money or broke even for the year.

If you owe money, look for the amount you owe on line 34, labeled "Amount You Owe." You can pay this amount directly to the IRS through their website, by mail, or by phone. The IRS also offers payment plans if you cannot pay the full amount at once.

If both line 33 and line 34 are blank or zero, you owe nothing and have no refund. This means your withholding or estimated payments matched your tax liability almost exactly.

Frequently Asked Questions

Is the amount on line 33 the same as what I will actually receive?

Usually yes, but not always. If you owe back taxes, child support, or have other federal or state debts, the IRS may intercept part or all of your refund. You will receive a notice if this happens. Otherwise, the amount on line 33 is what you will get.

Can I change the refund amount after I file?

Not directly. If you made an error on your return that affects line 33, you must file an amended return using Form 1040-X. The amended return will show a corrected refund amount, and the IRS will process the difference — either sending you more money or requesting payment if you owe.

What if line 33 shows a refund but I have not received it after 21 days?

Use "Where's My Refund?" on irs.gov and enter the amount from line 33. The tool will show whether the IRS has sent your refund and when to expect it. If the tool says your refund was sent but you have not received it, contact the IRS at 1-800-829-1040.

Does line 33 include state tax refunds?

No. Line 33 shows only your federal income tax refund. State tax refunds are handled separately by your state's tax agency and appear on your state return, not on Form 1040.

Why is my line 33 amount different from what my tax software calculated?

Tax software sometimes shows an estimate before you file. The IRS may adjust the amount slightly during processing due to credits, deductions, or payments that were not fully entered. Check your accepted return from the IRS to see the final amount on line 33.
