Key Facts
- Federal level: For 2025 returns filed in 2026, the basic gross-income threshold is $15,750 for a single person under 65, $23,625 for a head of household under 65, and $31,500 for a married couple filing jointly when both spouses are under 65.
- Federal level: Age, filing status, dependency status, and the kinds of income received can change the filing requirement.
- Federal level: A person can have to file below the ordinary gross-income threshold, including when net earnings from self-employment are at least $400 or certain special taxes or reporting situations apply.
- Federal level: Filing may still produce a refund when no return is required, such as when federal income tax was withheld or the person qualifies for a refundable credit.
- Federal level: A Form W-2 or Form 1099 is an information document, not a universal test of whether a federal return is required.
There is no single minimum income that answers whether everyone must file a federal tax return. The useful number depends first on the tax year and then on filing status, age, dependency status, and special filing rules. The current figures below apply to tax year 2025—the return generally filed during 2026.
2025 income thresholds for most taxpayers
For most U.S. citizens and resident aliens who cannot be claimed as dependents, the IRS uses gross income and the following thresholds:
- Single: $15,750 if under 65; $17,750 if 65 or older.
- Head of household: $23,625 if under 65; $25,625 if 65 or older.
- Married filing jointly: $31,500 if both spouses are under 65; $33,100 if one spouse is 65 or older; $34,700 if both are 65 or older.
- Married filing separately: $5 at any age.
- Qualifying surviving spouse: $31,500 if under 65; $33,100 if 65 or older.
Reaching a listed amount generally creates a filing requirement; the figures are not amounts of income that automatically become taxable dollar for dollar. The thresholds often track the standard deduction, but filing requirements and the final tax calculation are separate questions. Gross income generally includes money, property, goods, and services that are not exempt from federal income tax.
Why “how much did you make?” is only the first question
Filing status changes the applicable threshold. Federal tax law recognizes single, married filing jointly, married filing separately, head of household, and qualifying surviving spouse statuses. Marital status is generally determined at the end of the tax year, while the other classifications have additional legal tests.
Age also matters for most nondependent taxpayers because the threshold is higher at age 65. For the 2025 rules, a person born before January 2, 1961 is treated as age 65 or older at year-end. Blindness can affect the rules for dependents and the standard deduction, but it does not create a new filing status.
The relevant measure is gross income, not take-home pay, bank deposits, or adjusted gross income shown after certain deductions. Wages are one form of gross income, but taxable interest, dividends, capital gains, unemployment compensation, taxable retirement distributions, and the taxable portion of Social Security benefits can also matter. Income that is excluded from federal gross income ordinarily does not count toward the basic threshold, although a special filing rule may still apply.
Dependents use a different set of tests
A person who can be claimed as someone else’s dependent does not simply use the ordinary table. The 2025 dependent tests separately measure earned income, unearned income, and gross income. For a single dependent under 65 who is not blind, a return is required if unearned income exceeds $1,350, earned income exceeds $15,750, or gross income exceeds the larger of $1,350 or earned income up to $15,300 plus $450.
Unearned income includes categories such as taxable interest, ordinary dividends, capital-gain distributions, and some trust distributions. Earned income generally includes wages, salaries, tips, professional fees, and taxable scholarship or fellowship grants. Different dollar tests apply to married dependents and to dependents who are 65 or older or blind.
Dependency status can therefore make a relatively small amount of investment income significant even when wages remain below the ordinary single-filer threshold. Being claimed as a dependent also does not transfer every reporting duty to the person claiming the dependent.
Some situations require a return below the basic threshold
The gross-income table is only the general rule. A federal return is also required in several special situations listed in Publication 501.
Self-employment income
Net earnings from self-employment of at least $400 generally trigger a filing requirement. Net earnings are not the same as gross customer payments: the tax calculation generally begins with business income after allowable business expenses. A side business can therefore create a return requirement even when total gross income is below the ordinary filing-status threshold.
Special taxes and benefit-related rules
A return may be required when a person owes certain special taxes, including some Social Security and Medicare taxes, alternative minimum tax, or additional tax on a qualified retirement plan or other tax-favored account. A filing requirement can also arise when advance payments of the premium tax credit were made for the taxpayer, spouse, or dependent through the Health Insurance Marketplace. Household-employment taxes and some distributions from certain medical savings arrangements are among the other situations covered by the IRS table.
These exceptions show why a W-2 wage total cannot answer every filing question. The presence or absence of a Form 1099 is also not decisive: taxable income remains reportable under the governing rules even when no information return arrives, and receiving a form does not by itself establish the final filing result.
Filing a return and owing federal income tax are different
A person may be required to file yet owe no federal income tax after deductions, credits, payments, and withholding are applied. Conversely, a person below the ordinary filing threshold may have a filing duty because of self-employment tax or another special rule. The filing threshold is therefore an administrative trigger, not a promise about the final balance.
Voluntary filing can also be financially relevant. A return is generally needed to recover federal income tax withheld from pay or to claim refundable credits. The earned income tax credit, for example, requires an eligible person to file Form 1040 or Form 1040-SR even when that person otherwise has no filing requirement.
A short example of how the tests interact
Consider two simplified, nonpersonal examples for 2025. A single 30-year-old with $14,000 of wages and no other filing trigger is below the ordinary $15,750 gross-income threshold. A second person with $3,000 of gross receipts and $800 of net self-employment earnings is below that ordinary threshold but meets the separate $400 self-employment test.
The examples illustrate only the stated facts. A dependent classification, investment income, Marketplace coverage, special tax, or another source of income could change the analysis.
Why older threshold figures can mislead
Search results often preserve amounts from 2020, 2021, or another prior tax year. Federal filing thresholds are adjusted and official publications are issued for a specific return year. A figure from an earlier table should not be carried into a 2025 return.
Publication 501 is the IRS’s detailed annual reference for filing status, dependents, the standard deduction, and who must file. The IRS also provides an Interactive Tax Assistant that asks about filing status, withholding, and gross income, but its stated scope is generally limited to U.S. citizens and resident aliens for the full year. Nonresident and dual-status taxpayers are governed by additional federal rules.
Filing below the threshold can still matter
A return can claim a refund of withholding, estimated tax payments, or a refundable credit when the eligibility rules are met. That distinction is why “not required” does not always mean “no reason to file.” Claims for prior-year refunds are time-limited, and a previously filed return may need an amended tax return rather than another original return.
Federal thresholds do not decide state filing duties
These amounts address federal individual income tax returns. States set their own filing thresholds, residency rules, income definitions, and return requirements. Being below the federal threshold does not prove that no state return is required, and a state filing requirement does not by itself establish a federal one.
