Do I Need to File a Tax Return in 2026?

Income Thresholds by Filing Status for 2025

The gross income filing threshold is the point at which your income exceeds your standard deduction. Below that amount, your taxable income would be zero and no tax would be owed. Thresholds for 2025 include the temporary bonus amounts under the One Big Beautiful Bill Act (OBBBA), P.L. 119-21.

Single Filers Under 65

A single filer under 65 must file a federal tax return if gross income exceeds $15,750 for 2025. This equals the 2025 standard deduction of $15,000 plus the $750 OBBBA temporary bonus. Gross income includes wages, tips, self-employment income, interest, dividends, capital gains, rents, and most other income sources. Social Security benefits count toward gross income only to the extent they are taxable based on your combined income.

Single Filers 65 or Older

The threshold rises to $17,550 for single filers who are 65 or older as of December 31, 2025. You are considered age 65 on the day before your 65th birthday. This higher threshold reflects the additional standard deduction amount ($1,800 for 2025) that applies to older filers.

Married Filing Jointly Thresholds

MFJ filers have a threshold of $31,500 if both spouses are under 65. If one spouse is 65 or older, the threshold is $33,100. If both spouses are 65 or older, it rises to $34,700. These thresholds double the single amounts and account for the age add-on per qualifying spouse.

Head of Household Thresholds

Head of household filers under 65 must file if gross income exceeds $23,625. If the HOH filer is 65 or older, the threshold is $25,625. HOH status requires that you be unmarried (or considered unmarried) and paid more than half the cost of keeping up a home for a qualifying person for more than half the year.

Qualifying Surviving Spouse

Qualifying surviving spouse filers under 65 have a $31,500 threshold, the same as MFJ. If age 65 or older, the threshold is $33,100. QSS status applies for up to two years after the death of your spouse if you have a dependent child living with you.

When You Must File Even If Income Is Below the Threshold

The gross income threshold is not the only reason you may be required to file. Several special situations trigger a filing requirement independently of income level.

Self-Employment Income ($400 or More)

If your net earnings from self-employment reach $400 or more, you must file a tax return and attach Schedule SE. Net earnings equal gross self-employment income minus deductible business expenses. The $400 threshold applies to the net figure, not gross receipts.

The reason for this low threshold is that self-employed workers owe both the employee and employer portions of Social Security and Medicare taxes (15.3% combined on the first $176,100 of net SE income in 2025, plus 2.9% on earnings above that). These taxes would not be collected otherwise, since no employer is withholding them.

HSA and Archer MSA Distributions

If you received any distributions from a Health Savings Account (HSA) or Archer Medical Savings Account (MSA) during 2025, you must file Form 8889 (for HSAs) or Form 8853 (for Archer MSAs) regardless of your gross income level. The IRS uses these forms to determine whether distributions were used for qualified medical expenses and whether any distribution is taxable.

Advance Premium Tax Credit Payments

If you enrolled in a health insurance plan through a federal or state marketplace (HealthCare.gov or a state exchange) and received advance payments of the premium tax credit, you must file Form 8962 to reconcile those payments with your actual income. This is required even if your income is zero. Failing to reconcile advance credit payments can affect your ability to receive advance credits in future years.

Married Filing Separately - Effectively Any Income

Married filing separately filers must file a return if their gross income is $5 or more. In practice, if you choose MFS and have any income at all, you must file. Additionally, if your spouse itemizes deductions, you cannot take the standard deduction - you must also itemize. This makes the effective threshold even lower for many MFS filers.

Filing Requirements for Dependents - Students and Part-Time Workers

Dependents - children, students, and other individuals claimed on someone else's return - have different and generally lower filing thresholds than independent filers. The rules distinguish between earned income (wages, tips, self-employment) and unearned income (interest, dividends, capital gains, capital gain distributions).

Unearned Income Threshold

A dependent must file a return if their unearned income exceeds $1,350 for 2025. This threshold catches dependents who receive interest and dividends from custodial accounts or investments, even if they have no earned income at all.

Earned Income Threshold

A dependent with only earned income (wages from a part-time job) must file if their earned income exceeds $15,750 for 2025. This matches the threshold for an independent single filer because dependents can generally claim the same standard deduction on earned income.

Combined Income Rule

If a dependent has both earned and unearned income, they must file if their gross income exceeds the greater of $1,350 or their earned income plus $450 (not to exceed $15,750). In practice: add $450 to whatever earned income the dependent has, then compare that to their actual gross income. If gross income exceeds that amount, filing is required.

Example: A dependent earns $3,000 in wages and receives $800 in dividends. Gross income is $3,800. The test is: greater of $1,350 or ($3,000 + $450 = $3,450). Since $3,800 exceeds $3,450, the dependent must file.

When You Should File Even If Not Required

Not being required to file does not mean it is in your interest to skip it. In most situations involving any of the following, filing a return pays off financially or protects you legally.

Getting Back Withheld Taxes

If your employer withheld federal income tax from your paychecks during the year, that money is held by the IRS until you file a return. The IRS does not automatically issue refunds to workers who do not file. Failing to file means forfeiting your withheld taxes. The amount withheld is shown in Box 2 of your W-2.

Claiming the Earned Income Tax Credit

The Earned Income Tax Credit is a refundable credit for low-to-moderate income workers. For 2025, the maximum credit is $649 for workers with no qualifying children, up to $7,830 for workers with three or more qualifying children. Because it is refundable, the EITC can generate a refund even if you owe no tax. But you must file to receive it. The EITC is one of the most underclaimed tax benefits available. Use the EITC Eligibility Calculator to check whether you qualify.

Claiming the Additional Child Tax Credit

The Additional Child Tax Credit is the refundable portion of the Child Tax Credit. If your CTC exceeds your tax liability, the excess can be refunded up to $1,700 per qualifying child in 2025. Like the EITC, this refund only comes through filing. Families with children who are not required to file should still check whether they qualify.

Protecting Against Identity Theft

Fraudulent tax returns filed in someone else's name are a growing problem. If you are not required to file and do not, a fraudster can file a return in your name claiming a fake refund before you discover the identity theft. Filing your own return closes that window. Even a "zero return" creates an official record that prevents a duplicate.

Building Your Tax Filing Record

Tax returns are required for mortgage applications, student loan verification, and some immigration-related filings. Filing creates an official paper trail with the IRS that verifies your income history. Workers with irregular income often need prior-year returns when applying for loans or housing. Starting a filing record early is a low-cost protection.

Special Situations: Social Security, Foreign Income, and Household Employees

Social Security Income Only

If Social Security is your only income for the year, you generally do not need to file a federal tax return. Social Security benefits are only taxable if your combined income (AGI plus nontaxable interest plus half of Social Security benefits) exceeds $25,000 for single filers or $32,000 for married filing jointly. Below those combined income thresholds, Social Security is not taxable and the filing threshold analysis uses your regular gross income threshold.

Foreign Income

If you are a U.S. citizen or resident alien, your worldwide income is subject to U.S. tax. Foreign income counts toward your gross income for filing threshold purposes even if taxes were withheld by the foreign country. You may be able to exclude up to $130,000 of foreign earned income in 2025 under the Foreign Earned Income Exclusion (Form 2555), but you must file to claim the exclusion. Do not assume you are below the threshold without counting foreign income.

Household Employees

If you paid a household employee (nanny, housekeeper, home care aide) $2,700 or more in wages during 2025, you must file Schedule H with your return to report and pay household employment taxes. The requirement is tied to the employer's filing obligation, not the employee's income.

Church Employee Wages

If you received wages of $108.28 or more from a church or church-controlled organization that is exempt from employer FICA taxes, you must file a return and pay self-employment tax on those wages. This rule prevents church employees from escaping both Social Security payroll tax and SE tax entirely.
