The short answer: for most people, you have to file a 2026 federal return if your gross income is at least your standard deduction for your filing status. For a single person under 65, that's $16,100. Some situations, like self-employment profit of $400 or more, require a return at any income. And even if you don't have to file, you may want to, because it's the only way to get back tax that was withheld from your pay, or to claim credits that pay you money.
The income limits for 2026
If you're not someone else's dependent, you generally must file if your gross income for 2026 was at least the amount for your situation:
| Filing status | Age at the end of 2026 | You must file if gross income was at least |
|---|---|---|
| Single | Under 65 | $16,100 |
| Single | 65 or older | $18,150 |
| Head of household | Under 65 | $24,150 |
| Head of household | 65 or older | $26,200 |
| Married filing jointly | Both under 65 | $32,200 |
| Married filing jointly | One spouse 65 or older | $33,850 |
| Married filing jointly | Both 65 or older | $35,500 |
| Married filing separately | Any age | $5 |
| Qualifying surviving spouse | Under 65 | $32,200 |
| Qualifying surviving spouse | 65 or older | $33,850 |
These limits match the 2026 standard deduction plus the extra amount for people 65 and older. The new senior deduction of up to $6,000 doesn't change them.
What counts as gross income
Gross income is all the income you received that isn't tax-free, before any deductions. That includes:
- Wages, salaries and tips
- Self-employment and gig income (for a service business, your gross receipts before expenses)
- Interest and dividends
- Gains from selling stocks or property
- Unemployment benefits
- Retirement plan and IRA withdrawals that are taxable
- Rental income
- Gambling winnings
Social Security benefits usually don't count for this test. They do if you're married filing separately and lived with your spouse at any time in 2026, or if half your benefits plus all your other income, including tax-exempt interest, is more than $25,000 ($32,000 if married filing jointly).
You must file at any income if...
Some situations require a return no matter how little you earned. You generally must file if, in 2026, you:
- Had net self-employment earnings of $400 or more. Gig and freelance income explained.
- Got advance payments of the premium tax credit for Marketplace health insurance. You must file Form 8962 to settle up. Marketplace insurance and your return.
- Owe special taxes, such as tax on an early retirement account withdrawal, or Social Security and Medicare tax on tips you didn't report to your employer.
- Took money out of a health savings account (HSA) or a similar account.
- Earned $108.28 or more from a church or church-controlled organization that's exempt from employer Social Security and Medicare taxes.
If someone can claim you as a dependent
Dependents, like a student whose parents claim them, have their own lower limits. For 2026, a single dependent under 65 who isn't blind generally must file if any of these is true:
- Unearned income (like interest, dividends or investment gains) was more than $1,350
- Earned income (like wages from a part-time job) was more than $16,100
- Gross income was more than the larger of $1,350, or earned income (up to $15,650) plus $450
Example: Maya is 19, a full-time student, and her parents claim her. She earned $6,000 from a summer job and $200 of bank interest. Her unearned income ($200) is under $1,350, her earned income ($6,000) is under $16,100, and her gross income ($6,200) is under $6,450 ($6,000 + $450). She doesn't have to file. But if her employer withheld federal income tax, she should file to get it back.
Why file even if you don't have to
Not having to file isn't the same as not wanting to. You should file if any of these apply:
Tax was withheld from your pay
If your W-2 shows federal income tax withheld (box 2), the only way to get it back is to file. Many part-time and seasonal workers leave refunds on the table.
You qualify for the earned income credit
The earned income tax credit is refundable: if it's more than the tax you owe, you get the difference as a refund. People with low to moderate earnings, especially those with children, can get a meaningful amount, even with no tax withheld at all.
You qualify for the refundable part of the child tax credit
Families with qualifying children may get part of the child tax credit as a refund even when they owe no tax.
You made estimated payments or want to claim other refundable credits
Any estimated tax you paid in 2026, and some education credits, can only come back to you on a return.
It starts the clock
Filing starts the time limit the IRS generally has to review your return. It also gives you a prior-year return to sign next year's return with.
A quick self-check
- Did you have self-employment profit of $400 or more, or Marketplace insurance with advance help? File.
- Is your gross income at or above the limit in the table for your status and age? File.
- Did anyone withhold federal tax from your pay, or might you qualify for the earned income credit or child tax credit? You probably want to file.
- None of the above? You may not need to file. Keep your forms in case the IRS asks.
Frequently asked questions
I only had a small part-time job. Do I need to file? If your gross income was under the limit for your situation and none of the special cases apply, no. But check box 2 of your W-2: if tax was withheld, filing gets it back.
I'm retired and only get Social Security. Do I need to file? Usually not, unless half your benefits plus any other income is over $25,000 ($32,000 jointly), or you're married filing separately.
What if I'm not sure? Filing when you didn't need to doesn't hurt you, and it's free with Navo for the 2027 season. Navo asks about your income and tells you what applies.
When is the deadline? For most people, April 15, 2027. If you're due a refund and don't have to file, there's no penalty for filing late, but you generally have three years to claim it.
