When Seniors Don't Need to File a Tax Return - and When You Should Anyway

Not everyone who receives income is required to file a federal tax return. For seniors on modest fixed incomes, this can mean a legitimate year with no return due - and no penalty for not filing one. But knowing when you truly do not need to file, versus when skipping would cost you money, requires a clear look at both the rules and the exceptions.

The Basic Filing Threshold

The IRS requires you to file a federal return if your gross income equals or exceeds a set threshold. For 2025, those general thresholds (which adjust annually) were approximately:

• Single, age 65 or older: roughly $16,550
• Married filing jointly, both spouses 65 or older: roughly $30,700
• Married filing jointly, one spouse 65 or older: roughly $29,200
• Married filing separately, any age: roughly $5 (this threshold is very low regardless of age)
• Head of household, age 65 or older: roughly $23,850

These thresholds are higher for people 65 and older than for younger taxpayers because the additional standard deduction available at 65 is already built into the calculation. If your gross income falls below your threshold, you are not required to file. But see the exceptions below before you decide not to.

What Counts as Gross Income?

Gross income for filing purposes includes wages, pension payments, traditional IRA and 401(k) withdrawals, taxable interest, dividends, rental income, self-employment income, and the taxable portion of Social Security. What is notably excluded from gross income (and therefore does not count toward the threshold) includes Supplemental Security Income (SSI), most veterans' benefits, and - for qualifying people - gifts and inheritances.

Social Security benefits require a bit of extra care. If Social Security is your only income and it falls below the taxable combined income thresholds, it does not count toward your gross income for filing purposes and you generally do not need to file. But if you also receive other income sources, a portion of Social Security may become taxable and must be included.

When You Are Not Required to File But Might Want To

There are several situations where filing is not required but still makes financial sense:

• You had taxes withheld - if your pension, part-time employer, or IRA custodian withheld federal income taxes from your payments, filing a return is the only way to get a refund of any overpaid amount. If you do not file, you simply forfeit that money.
• You are eligible for a refundable credit - the Earned Income Credit (EITC) is available to workers over 65 with low income. If you had any earned income (wages, tips, self-employment), you may qualify and receive a credit even if you owe no taxes. The credit is only paid out if you file.
• You want to start the statute of limitations - the IRS generally has three years from the date you file to audit a return. If you never file, that clock never starts. For most people this is not a concern, but it is worth knowing.

Situations That Always Trigger a Filing Requirement

Regardless of your income level, you are required to file a return in certain situations:

• You received advance premium tax credits through a health insurance marketplace and need to reconcile them
• You owe the Alternative Minimum Tax (AMT)
• You have net earnings from self-employment of $400 or more
• You received wages from a church or qualified church-controlled organization that did not withhold Social Security and Medicare taxes
• You received distributions from a health savings account (HSA) that were not used for qualified medical expenses

What About State Returns?

State filing requirements are separate from federal requirements and are often lower. Some states require a return at income levels well below the federal threshold. Check your own state's department of revenue website for current state filing thresholds. AARP Foundation Tax-Aide volunteers can also help you determine whether a state return is needed.
