Do I Need to File Taxes? Income Thresholds and Filing Status

You need to file a federal tax return if your gross income for the year reaches the threshold set for your filing status and age. For tax year 2025 (the return due in April 2026), that threshold is $15,750 for a single filer under 65 and $31,500 for a married couple filing jointly, both under 65.¹ Several other situations force a return at much lower income, so the income test is only the starting point.

The 2025 Income Thresholds

The IRS ties the filing threshold to the standard deduction: if your gross income sits below the deduction amount for your status, you generally owe no tax and don’t have to file.² For tax year 2025, the thresholds are:¹

Single, under 65: $15,750
Single, 65 or older: $17,750
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
Married Filing Separately, any age: $5
Qualifying Surviving Spouse, under 65: $31,500
Qualifying Surviving Spouse, 65 or older: $33,100

Gross income means all money, goods, property, and services you receive that aren’t specifically exempt from tax. Wages, taxable interest, dividends, rental income, and gains from selling property all count, measured before any deductions or adjustments. If the total for your household crosses the number above, you’re required to file.

The age bump at 65 is already baked into those thresholds. It comes from an additional standard deduction of $2,000 for unmarried filers and surviving spouses, and $1,600 for married filers, once you turn 65.²

Picking the Right Filing Status

The threshold that applies to you depends on which of the five filing statuses fits your situation on the last day of the tax year:³

Single, if you’re unmarried, divorced, or legally separated.
Married Filing Jointly, if you’re married and filing one return with your spouse, or your spouse died during the tax year.
Married Filing Separately, if you’re married but file your own return apart from your spouse. The threshold here is just $5.
Head of Household, if you’re unmarried and paid more than half the cost of maintaining a home for yourself and a qualifying dependent.
Qualifying Surviving Spouse, if your spouse died within the past two years and you have a dependent child.

Read the threshold table using the status that matches you and your age at the end of 2025.

Self-Employment Changes the Answer

If you freelance, contract, drive for a platform, or run a side business, the filing rule shifts. Net self-employment earnings of $400 or more require a return, no matter how low your other income is.⁴ Net earnings are what’s left after you subtract ordinary business expenses from what you took in.

The reason the threshold drops so sharply is self-employment tax. You owe Social Security and Medicare contributions that an employer would normally withhold, and the IRS collects those through your return. This applies regardless of age, even if you’re already collecting Social Security benefits.

Rules for People Claimed as Dependents

If a parent or someone else can claim you as a dependent — a common situation for teenagers with part-time jobs or college students living at home — you may still need to file your own return. The rules turn on the type of income. For a dependent under 65 in tax year 2025:⁵

With only earned income (wages, tips, salary), file if that income exceeds $15,750.
With only unearned income (interest, dividends, capital gains), file if that income exceeds $1,350.
With both, file if gross income exceeds the larger of $1,350 or earned income (up to $15,300) plus $450.

A dependent who is 65 or older gets higher numbers; the unearned income threshold, for example, rises to $3,350 for a single dependent that age.⁵ Because the unearned income floor is so low, even a modest custodial savings account or a few dividend payments can create a filing obligation for a child.

Other Situations That Require a Return

Some conditions force you to file even when your income sits under the standard threshold:

Married Filing Separately with gross income of $5 or more.¹
Net self-employment earnings of $400 or more, as described above.
Foreign financial accounts whose combined value tops $10,000 at any point during the year. That triggers a separate Report of Foreign Bank and Financial Accounts (FBAR) on top of any tax return.⁶
Digital asset sales at a gain. That gain counts toward gross income and may push you over the threshold; starting with tax year 2026, brokers report those sales on Form 1099-DA.⁷

Certain special taxes also require a return on their own: the alternative minimum tax, early-withdrawal penalties on retirement accounts, and household employment taxes for a nanny or housekeeper. Publication 501 lists these in full.¹

When You Should File Even If You Don’t Have To

Being under the threshold means you aren’t required to file. It doesn’t mean filing is a bad idea. Two situations regularly put money in the hands of people who would otherwise skip a return.

First, withholding. If your employer took federal income tax out of your paychecks and your income ends up below the threshold, you very likely overpaid. The IRS keeps that money unless you file a return to claim it.

Second, refundable credits. These can pay you more than you owe in tax, arriving as a direct payment:⁸

The Earned Income Tax Credit, worth up to $8,046 for a family with three or more qualifying children in tax year 2025, and up to $649 for workers without children.⁹
The Child Tax Credit, up to $2,200 per qualifying child for 2025, with a refundable portion (the Additional Child Tax Credit) of up to $1,700 per child for filers with little or no tax liability.¹⁰

Seniors 65 and older should also look at the enhanced deduction of up to $4,000 per person available for tax years 2025 through 2028, which phases out above $75,000 in modified adjusted gross income ($150,000 for joint filers).¹¹ It doesn’t change whether a return is required, but it can lower a tax bill enough to make filing worthwhile for someone near the threshold.

Add Up Your Income Before You Decide

Before concluding you’re under the threshold, gather every income document that arrives in January and February and add the amounts together. Common forms include:

Form W-2 from an employer, showing annual wages and federal tax withheld.¹²
Form 1099-NEC for freelance or contract payments of $600 or more.
Form 1099-K for payments processed through third-party networks.
Forms 1099-INT and 1099-DIV for interest and dividend income.
Form SSA-1099 for Social Security benefits.
Form 1099-DA for digital asset sale proceeds, beginning with tax year 2026.⁷

The wages figure in Box 1 of your W-2 plus the income boxes on your 1099s gives you gross income. Compare that number against the threshold for your status and age. If it’s over, you file. If it’s under, run through the self-employment, dependent, and special-situation rules above, and then decide whether refunds or credits make filing worthwhile anyway.
