Do You Have to File Taxes Every Year? Thresholds and Exceptions

You don’t have to file a federal tax return every year. Whether you have to file taxes in a given year depends mainly on how much you earned, how you earned it, your filing status, and your age. For most people, the trigger is a gross income threshold tied to the standard deduction: earn less than that number and, in most cases, no return is required. But several situations force a filing at much lower income levels, and sometimes it pays to file even when you don’t have to.

Income Thresholds That Trigger a Return

For the 2025 tax year (the return filed in 2026), you generally must file if your gross income reaches these amounts:¹

Single, under 65: $15,750
Single, 65 or older: $17,550
Head of household, under 65: $23,625
Head of household, 65 or older: $25,625
Married filing jointly, both under 65: $31,500
Married filing jointly, one spouse 65 or older: $33,100
Married filing jointly, both 65 or older: $34,700
Qualifying surviving spouse, under 65: $31,500
Qualifying surviving spouse, 65 or older: $33,100
Married filing separately, any age: $5

Filers 65 and older get a higher cutoff because of the additional standard deduction available at that age. The married-filing-separately threshold is unusually low at $5 because when one spouse itemizes, the other spouse’s standard deduction drops to zero, making nearly all income reportable.

Gross income here includes wages, tips, interest, dividends, rental income, business profits, capital gains, and most other economic gain, including income earned outside the United States. Gifts and inheritances don’t count. Social Security benefits usually don’t count either, but a portion can become taxable if your combined income (half your benefits plus all other income, including tax-exempt interest) tops $25,000 for single filers or $32,000 for joint filers. If Social Security was your only income for the year, you generally don’t need to file.²

Full filing requirement tables, including edge cases, appear in IRS Publication 501.³

If Someone Else Can Claim You as a Dependent

Dependents follow a separate set of thresholds. A single dependent under 65 in 2025 must file if any of the following is true:⁴

Unearned income (interest, dividends, capital gains) exceeded $1,350
Earned income (wages, salary, tips) exceeded $15,750
Gross income exceeded the larger of $1,350, or earned income up to $15,300 plus $450

Dependents who are 65 or older or blind have higher thresholds. The unearned income cutoff, for example, rises to $3,350 for a single dependent who is either 65 or older or blind. Married dependents run into stricter rules: if a spouse files separately and itemizes, the filing floor can be as low as $5 of gross income.

Self-Employment: The $400 Rule

If your net self-employment earnings reach $400 or more, you must file a federal return, even if your total income is well below the standard deduction.⁵ This applies to freelancers, gig workers, and small business owners. The reason is Social Security and Medicare: self-employed workers owe both halves of those payroll taxes (called self-employment tax), and a filed return is how the IRS assesses and collects them.

Situations That Require Filing at Any Income Level

Several specific events force a return regardless of how little you earned:³

You owe Alternative Minimum Tax.
You paid a household employee (nanny, housekeeper, caregiver) $3,000 or more in cash wages during 2026 and owe Social Security and Medicare taxes on those wages.⁶
You took a distribution from a Health Savings Account or Archer MSA.
You received advance payments of the Premium Tax Credit through the health insurance marketplace. You must file to reconcile those payments against your actual income; skipping this step can end future advance payments.⁷

Foreign Accounts and Assets

Holding money outside the United States creates separate reporting duties. If your foreign financial accounts combined exceeded $10,000 at any point in the year, you must file FinCEN Form 114 (the FBAR) with the Financial Crimes Enforcement Network. It’s separate from your tax return, though it shares the April 15 deadline and has an automatic extension to October 15.⁸

Higher-value holdings may also require Form 8938, filed with your tax return. A single U.S.-based filer must file it once foreign financial assets exceed $50,000 on the last day of the year or $75,000 at any point during the year; for joint filers, the thresholds are $100,000 and $150,000.⁹

When It Pays to File Even If You Don’t Have To

Filing when it isn’t required can still put money in your pocket. A few reasons to file anyway:

Refund of withheld tax. If your employer withheld federal income tax from your paychecks but your income was under the filing threshold, filing a return is the only way to get that money back.
Earned Income Tax Credit. For 2025, the EITC ranges from $649 with no qualifying children up to $8,046 with three or more, depending on income and filing status. It’s refundable, meaning you can receive it even if you owe no tax.¹⁰
Child Tax Credit. Up to $1,700 per qualifying child is refundable as the additional child tax credit, limited to 15% of your earnings above $2,500.

There’s a deadline on all of this. You have three years from the original due date to file and claim a refund. Miss that window and the money goes to the U.S. Treasury permanently.¹¹ A 2025 return, normally due April 15, 2026, must be filed by April 15, 2029, to preserve any refund.

What Happens If You Skip a Required Return

The failure-to-file penalty is 5% of the unpaid tax for each month (or partial month) the return is late, capped at 25%.¹² If a return is more than 60 days late, the minimum penalty becomes $525 or 100% of the unpaid tax, whichever is less.¹³ Interest also runs on unpaid balances at a rate set quarterly, currently 7% per year, compounded daily.¹⁴

The failure-to-file penalty is separate from the failure-to-pay penalty and much steeper. Failure-to-pay runs at 0.5% per month of the unpaid balance, capped at 25%, and drops to 0.25% per month if you’re on an approved payment plan.¹⁵ If you owe tax and can’t pay in full, file on time anyway and pay what you can; that alone eliminates the larger of the two penalties.

First-time penalty abatement is available if you filed all required returns for the previous three tax years and had no penalties during that period. You don’t need to use any special phrasing when asking for it; the IRS checks your account and applies the waiver if you qualify. Reasonable-cause relief (serious illness, natural disaster, incorrect professional advice) is also possible.¹⁶

No Statute of Limitations on Unfiled Returns

Once you file, the IRS generally has three years to audit or assess additional tax, extending to six years if you omitted more than 25% of your gross income.¹⁷¹⁸ If you never file, there is no time limit. The IRS can assess tax against you at any point in the future and may prepare a substitute return on your behalf, typically without any of the deductions or credits you’d have claimed. Filing, even late, starts the clock.

State Returns Follow Their Own Rules

Meeting or missing the federal threshold doesn’t answer the state question. Nine states have no income tax on wages; the rest set their own thresholds, some tied to the federal standard deduction and some using different formulas. You may owe a state return even when no federal return is required, or the reverse. Check your state tax agency’s guidance before assuming you’re done.
