The taxes you get back are the ones you overpaid: federal income tax, state income tax, and, in some cases, excess Social Security tax. Refundable credits can add to that refund or create one even when you owed no tax. Sales tax, excise taxes on things like gasoline and alcohol, and property tax are not refundable through your return, and neither is the employer’s matching share of payroll tax. So the practical answer to what taxes do you get back comes down to income taxes you prepaid, Social Security tax you overpaid across multiple jobs, and credits Congress designed to pay out in cash.
Why You End Up With Anything to Refund
The federal system runs pay-as-you-go. Your employer withholds income tax from each paycheck based on the Form W-4 you filled out at hiring, which tells them your filing status, dependents, and whether you want extra withheld. Many people set their W-4 conservatively to avoid owing in April, which means they overpay a little with every check.
Self-employed workers and people with meaningful investment income pay the same obligation through quarterly estimated payments, which cover both income tax and self-employment tax for Social Security and Medicare. Either way, every dollar paid in during the year lands on the same ledger.
When you file, you calculate what you actually owe on your income, deductions, and filing status, then compare that number against what you paid in. Paid more than you owe? You get a refund. Paid less? You owe the balance. A large refund means you effectively gave the government an interest-free loan all year.
Federal and State Income Tax Withholding
Excess federal income tax withholding is the single biggest driver of most refunds. Your employer estimates your tax from what you reported on the W-4, but that estimate can’t anticipate everything: deductions you claim at filing, a mid-year income change, or a life event like having a child all open gaps between what was withheld and what you actually owe.1Internal Revenue Service. Topic No. 753, Form W-4, Employees Withholding Certificate
State income tax works the same way. If your state has an income tax, your employer withholds for it, and any overpayment comes back as a separate state refund. Processing times vary, but most states that collect income tax turn around e-filed returns in a few weeks to a few months.
For 2026, the standard deduction is $16,100 for single filers, $24,150 for heads of household, and $32,200 for married couples filing jointly.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 If your withholding was set without accounting for the full standard deduction or other adjustments you qualify for, a refund is the likely result.
Excess Social Security Tax From Multiple Jobs
Here is a refund people frequently miss. Social Security tax (6.2% of wages) only applies up to an annual wage cap. For 2026, that cap is $184,500, which puts the maximum Social Security tax any one worker should pay at $11,439.3Social Security Administration. Contribution and Benefit Base A single employer stops withholding at the threshold. But if you held two or more jobs, each employer withholds independently with no idea what the others took out, and you can easily blow past the cap.
You claim the overpayment on Schedule 3 of Form 1040, and it flows into your refund like any excess income tax withholding. Only the employee’s portion is refundable this way; employers do not get their matching share back. If your combined W-2 wages topped $184,500 in 2026, add up the Social Security tax figures from all your W-2s and claim the excess.
Refundable Credits That Can Add to Your Refund
Refundable credits are the strongest refund boosters because they can pay you cash even when your tax is zero. If a refundable credit exceeds your tax bill, the IRS sends you the difference.
Earned Income Tax Credit
The EITC targets low- and moderate-income workers and can be worth up to $8,231 for 2026 with three or more qualifying children.2Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 The amount scales with income, filing status, and number of children. Workers without qualifying children can still claim a smaller EITC. If you have a qualifying child, Schedule EIC goes with your return.4Internal Revenue Service. About Schedule EIC (Form 1040 or 1040-SR), Earned Income Credit
Additional Child Tax Credit
The Child Tax Credit for 2026 is worth up to $2,200 per qualifying child, but only part of it is refundable. That refundable piece, the Additional Child Tax Credit, pays out up to $1,700 per child even if your tax bill is zero. You need at least $2,500 in earned income to qualify for it.5Internal Revenue Service. Child Tax Credit For families with little or no federal tax, the ACTC is often the largest single component of the refund.
Heads up on timing: by law, the IRS cannot issue any refund that includes the EITC or ACTC before mid-February, no matter how early you file, and the hold applies to the whole refund, not just those credits.6Internal Revenue Service. When to Expect Your Refund if You Claimed the Earned Income Tax Credit or Additional Child Tax Credit
American Opportunity Tax Credit
The AOTC covers up to $2,500 per eligible student for qualified college expenses during the first four years of higher education. Forty percent of the credit, up to $1,000, is refundable, so a student or parent with no tax liability can still get $1,000 back.7Internal Revenue Service. Refundable Tax Credits The credit phases out at modified adjusted gross income above $90,000 for single filers and $180,000 for married couples filing jointly.
Premium Tax Credit
If you bought health insurance through the Marketplace, the Premium Tax Credit is fully refundable. Many people take an advance version each month, applied to their premium. At filing, Form 8962 reconciles the amount: if you received too much in advance, you repay part; if you received too little, the balance gets added to your refund.8Internal Revenue Service. Premium Tax Credit (PTC) Overview For 2026, eligibility generally runs from 100% to 400% of the federal poverty line.
Non-Refundable Credits Can’t Cash Out on Their Own
Non-refundable credits erase your tax bill down to zero but will not generate a refund by themselves. Their indirect effect is still real: when a non-refundable credit wipes out your liability, every dollar of withholding you already paid becomes refundable.
The Child and Dependent Care Credit covers a percentage of what you pay for childcare or dependent care so that you can work; the percentage depends on income, and the credit applies to a limited amount of expenses. For tax years after 2021, it is non-refundable again. The Lifetime Learning Credit offers up to $2,000 per return (20% of the first $10,000 in qualified education expenses) for undergraduate, graduate, or professional courses, with no limit on the number of years you can claim it, but it is non-refundable too.9Internal Revenue Service. Lifetime Learning Credit Neither will hand you cash when your tax balance is already zero, but either can get your withholding back in full.
Taxes You Can’t Get Back
Not every tax you pay shows up on your refund. Sales tax, excise taxes on gasoline and alcohol, and property taxes are final when you pay them. Nothing on your return will return the sales tax from last year’s purchases or the gas tax embedded in every fill-up. The employer’s half of Social Security tax is also not refundable to you, even when you recover the employee half from working multiple jobs.
Some of those taxes can still shrink your federal bill indirectly through the State and Local Tax deduction. If you itemize on Schedule A, you can deduct state and local income taxes (or sales taxes, not both), plus property taxes, up to a combined cap. For 2026 that cap is $40,400.10Internal Revenue Service. Instructions for Schedule A (Form 1040) The deduction does not refund those taxes; it lowers your taxable income, which lowers your federal liability, which can widen the gap between what you paid and what you owe. Whether itemizing beats the standard deduction depends on whether your total itemized deductions exceed $16,100 (single) or $32,200 (married filing jointly) for 2026.2Internal Revenue Service.

When the Government Keeps Your Refund
Even when you have overpaid and a refund is owed, the government can take some or all of it to satisfy certain debts. Under the Treasury Offset Program, the Bureau of the Fiscal Service can reduce your refund to pay:
- Past-due child support, satisfied before any other offset.
- Defaulted student loans and other non-tax debts owed to federal agencies.
- Back taxes owed to your state.
- Overpayments or unpaid contributions owed to a state unemployment fund.
If your refund is reduced, the Bureau of the Fiscal Service sends a notice showing the original refund amount, how much was taken, and which agency received the payment.11Internal Revenue Service. Reduced Refund
Joint filers face a particular risk. If your spouse owes one of these debts, the entire joint refund can be offset, including your share. To protect your portion, file Form 8379, Injured Spouse Allocation, with your return or afterward. The IRS will calculate what belongs to each spouse and release the non-debtor spouse’s share.12Internal Revenue Service. Instructions for Form 8379, Injured Spouse Allocation
One Catch on Last Year’s State Refund
Getting a state refund back is not always the end of the story. The IRS may treat part or all of a state income tax refund as taxable income the following year. The test is whether you got a federal tax benefit from deducting those state taxes: if you itemized and deducted state income taxes on your prior-year federal return, and the state later refunded some of that money, the refund is taxable to the extent you benefited from the deduction.
Your state refund is generally not taxable if you took the standard deduction the prior year, or if you deducted state sales taxes instead of income taxes. The SALT cap matters too: if your state and local taxes exceeded the cap and you could only deduct up to the capped amount, a refund of taxes above the cap gave you no federal benefit and is not taxable. Your state sends a Form 1099-G reporting the refund, and the Taxable Refund Worksheet in the Form 1040 instructions walks through the calculation.
