A 19-year-old named Ellie earned $9,200 last summer at a restaurant, had $480 in federal tax withheld from her paychecks, and assumed she didn't need to file because she "didn't make enough." She was right about the filing requirement. She was wrong about skipping the return. That $480 withheld? She could have gotten every penny back. Instead, the IRS kept it.
Filing requirements and filing benefits are two different questions. The first asks: does the IRS legally require you to submit a return? The second asks: would you benefit from filing one even if they don't? Millions of Americans answer "no" to the first question and never consider the second.
30-Second Summary: You must file a federal tax return if your gross income exceeds the standard deduction for your filing status and age, or if you have $400+ in net self-employment earnings. Even if you're not required to file, doing so can get you a refund of withheld taxes and valuable credits like the EITC.
The Basic Rule: Income vs. Standard Deduction
For most people, the filing threshold is simple: if your gross income is at or above the standard deduction for your filing status and age, you must file. [1]
Gross income means all income from all sources (wages, interest, dividends, freelance work, rental income) that isn't specifically exempt from tax. It's everything before deductions.
2025 Filing Thresholds (Returns Filed in 2026)
| Filing Status | Under 65 | 65 or Older |
|---|
| Single | $15,750 | $17,750 |
| Married filing jointly (both under 65) | $31,500 | — |
| Married filing jointly (one 65+) | — | $33,100 |
| Married filing jointly (both 65+) | — | $34,700 |
| Head of household | $23,625 | $25,625 |
| Married filing separately | $5 | $5 |
| Qualifying surviving spouse | $31,500 | $33,100 |

The married-filing-separately threshold of $5 is not a typo. If your spouse itemizes deductions, your threshold is effectively zero.

Special Situations That Require Filing
Income thresholds aren't the only trigger. You must file regardless of income if: [2]
Self-employment income of $400 or more. Sold crafts on Etsy? Drove for Uber? Did freelance consulting? If net earnings (revenue minus expenses) hit $400, you file. The threshold is shockingly low and catches many gig workers. You owe self-employment tax (Social Security + Medicare) on that income.
Marketplace health insurance with advance premium tax credits. If you got subsidized health insurance through the ACA marketplace, you must file to reconcile the credits. Skipping this can mean repaying the entire subsidy.
Owing special taxes. Alternative minimum tax, household employment taxes (nanny tax), taxes on early retirement distributions, or unreported tip income all trigger filing requirements.
HSA or MSA distributions. If you or your spouse received distributions from a health savings account, Archer MSA, or Medicare Advantage MSA.
Dependent Filing Rules
Dependents have lower filing triggers, especially for unearned income.
| Income Type | Filing Trigger (Under 65) |
|---|
| Unearned income only (interest, dividends) | Over $1,350 |
| Earned income only (wages) | Over $15,750 |
| Both types | More than the larger of $1,350 or earned income (up to $15,300) + $450 |
Source: IRS [1]
A teenager with $2,000 in dividend income from a custodial account at Fidelity must file, even though they might only earn $3,000 from a summer job. The unearned income threshold is much lower than the earned income threshold.
The dependent is legally responsible for filing their own return. Parents can prepare it, but it's the dependent's obligation.
Why You Should File Even When You Don't Have To
Ellie's situation is more common than you'd think. Here are the reasons to file when the IRS doesn't require it:
Get your withheld taxes back. If any federal income tax was withheld from your paychecks (check your W-2, box 2), the only way to get that money back is to file a return. No return, no refund.
Claim refundable tax credits. The Earned Income Tax Credit can be worth up to $8,046 for families with three or more children. [3] The refundable portion of the Child Tax Credit can be worth up to $1,700 per child. [4] The American Opportunity Tax Credit is 40% refundable (up to $1,000) even if you owe zero tax. [5] These credits can put cash in your pocket even if your income is too low to owe taxes.
Start the statute of limitations clock. The IRS has three years to audit a filed return. If you never file, the clock never starts. That's an open invitation for scrutiny, forever.
Build documentation. Lenders, landlords, and immigration authorities may require recent tax returns. A zero-income return creates a paper trail.
Here's a reality check: about 63% of returns filed result in refunds, averaging $3,167. [6] Many low-income filers leave thousands on the table by not filing at all.
The Senior Bonus Deduction (2025–2028)
A new temporary provision adds $6,000 to the standard deduction for taxpayers 65 and older (or $12,000 if both spouses are 65+). Income limits apply: modified AGI of $75,000 or less (single) or $150,000 or less (married filing jointly). [7]
This doesn't change the filing threshold itself, but it can reduce your tax bill to zero even if your income is well above the threshold. You'd still need to file to claim it.
State Filing Requirements
Federal and state requirements are separate. You may need to file a state return even if you don't need to file federally, and vice versa.
Nine states have no income tax on wages. [8] The other 41 have their own thresholds, and many are lower than the federal thresholds. Check your state's tax department website, or see our state income tax guide for an overview.
