Whether retired people have to file taxes comes down to one question: does your gross income clear the filing threshold for your age and filing status? For the 2026 tax year, a single filer age 65 or older generally doesn’t have to file until gross income reaches about $18,150, and a married couple filing jointly where both spouses are 65 or older isn’t required to file until roughly $35,500. Plenty of retirees stay under those numbers on Social Security alone. Plenty of others clear them easily once a pension or an IRA withdrawal lands on top.
2026 Filing Thresholds by Age and Status
The filing threshold tracks the standard deduction for your filing status, plus an extra amount if you’re 65 or older. For 2026, the base standard deductions are:
- Single: $16,100
- Married filing jointly: $32,200
- Head of household: $24,150
Add the age-based amount if you qualify. A single filer 65 or older adds $2,050, bringing the filing threshold to $18,150. Each spouse 65 or older in a joint return adds roughly $1,650, so a couple where both have reached 65 doesn’t need to file until gross income hits about $35,500.1Internal Revenue Service.

If your gross income stays below the applicable number, filing is generally not required. Cross it, and you have to file even if credits and deductions zero out your actual tax bill.
What Counts as Gross Income
Gross income here means all taxable income, not just wages. For a typical retiree, that includes:
- Pension and annuity payments
- Traditional IRA and 401(k) withdrawals
- The taxable portion of Social Security
- Interest from savings accounts and CDs
- Ordinary dividends and capital gains
- Rental income
Distributions from traditional pensions, annuities, traditional IRAs, and 401(k) plans are fully taxable as ordinary income if every contribution went in pre-tax. If you contributed some after-tax dollars, only the growth and the pre-tax portion counts. For most retirees drawing from these accounts, the full distribution lands in gross income.
How Social Security Factors In
Social Security benefits are taxed on a sliding scale based on your “combined income,” which is your adjusted gross income plus any tax-exempt interest plus half of your Social Security benefits. Congress set these thresholds in 1993 and never indexed them for inflation, so more retirees cross them each year.2Office of the Law Revision Counsel. 26 USC 86 – Social Security and Tier 1 Railroad Retirement Benefits
For a single filer, combined income between $25,000 and $34,000 makes up to 50% of benefits taxable. Above $34,000, up to 85% becomes taxable. For married couples filing jointly, the equivalent thresholds are $32,000 and $44,000.3Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits
If Social Security is your only income and the benefit is modest, your combined income will likely stay under $25,000, nothing is taxable, and you probably don’t need to file. Add a pension or IRA withdrawal and the taxable share climbs fast. A retiree collecting $24,000 in Social Security and $20,000 from a traditional IRA has a combined income of $32,000 ($20,000 + $0 + $12,000), which makes 50% of the Social Security taxable.3Internal Revenue Service. Publication 915 – Social Security and Equivalent Railroad Retirement Benefits
The practical point: only the taxable share of Social Security counts toward your gross income for filing purposes. If none of your benefits are taxable, none of them push you toward the threshold.
Income That Doesn’t Count
Qualified distributions from Roth IRAs and Roth 401(k)s are not part of gross income and don’t move you toward the filing threshold at all. To qualify, the account must have been open at least five years, and you must be 59½ or older, disabled, or using up to $10,000 for a first home purchase.4Internal Revenue Service. Publication 590-B – Distributions from Individual Retirement Arrangements
Roth accounts are also exempt from required minimum distributions during the owner’s lifetime, so they never create a forced taxable event.
Life insurance proceeds, gifts, inheritances, and the return-of-basis portion of annuity payments also stay out of gross income.
The $400 Self-Employment Rule Overrides Everything
Any retiree with $400 or more in net self-employment income has to file, full stop. Age, Social Security status, and total gross income don’t matter.5Internal Revenue Service. Self-Employment Tax – Social Security and Medicare Taxes
Freelance consulting, selling crafts online, driving for a rideshare service, and similar gig work all count. The $400 figure is net profit after business expenses, not gross revenue, but it’s still a low bar. Self-employment tax covering Social Security and Medicare applies on top of regular income tax.
Required Minimum Distributions Can Force You Over
Traditional retirement accounts eventually force taxable withdrawals whether you want them or not. If you were born between 1951 and 1959, required minimum distributions from traditional IRAs, 401(k)s, and similar accounts begin at age 73. For anyone born in 1960 or later, the starting age is 75.6Office of the Law Revision Counsel. 26 USC 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans
Your first RMD is due by April 1 of the year after you reach the applicable age. Every RMD after that is due by December 31. Delaying the first one to April 1 means taking two RMDs in the same calendar year, which can push you into a higher bracket and increase how much of your Social Security is taxable.
Miss an RMD and the penalty is 25% of the amount you should have withdrawn, dropping to 10% if you catch and correct it within two years.7Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
RMDs are fully taxable ordinary income and go straight into gross income. For retirees with sizable traditional balances, RMDs alone can lift them past the filing threshold.
Filing Even When You Don’t Have To
Being under the threshold doesn’t mean filing is pointless. If your pension administrator or the Social Security Administration withheld federal income tax from your payments during the year, filing a return is the only way to get that money back.8Internal Revenue Service. Refundable Tax Credits
Refundable tax credits are the other reason. Unlike regular credits that stop at zero tax owed, refundable credits pay out the excess as a refund. Retirees working part-time or raising dependent grandchildren sometimes qualify for credits they’d miss by not filing.
A Note on State Taxes
Federal filing is only half the question. Nine states have no broad-based income tax, so retirees there have no state filing obligation. Several more exempt some or all retirement income, including pensions, IRA distributions, and Social Security. Most states, though, tax at least some retirement income and set their own thresholds. If your state has an income tax, check its rules separately before assuming you’re off the hook.
