There is no age at which you stop paying federal taxes. Whether you owe tax, and whether you even have to file a return, depends on how much income you receive, not how old you are. What does change with age is how much income you can receive before any of it is taxed. Turning 65 unlocks a larger standard deduction, and a 2025 law added a sizable new deduction for seniors on top of it. For retirees living on modest Social Security and retirement account withdrawals, those breaks can bring the federal tax bill to zero.
When You Don’t Have to File a Return
The IRS only requires a return once your gross income passes a threshold tied to your standard deduction. For the 2026 tax year, the basic standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026 Filers 65 or older add an age-based amount on top.2Internal Revenue Service. Topic No. 551, Standard Deduction If your gross income stays under your total standard deduction, you generally owe nothing and may not need to file.
File anyway if federal tax was withheld from a pension or from Social Security, since filing is the only way to get that money back. The same goes for any refundable credit you qualify for.
What Changes at Age 65
A Larger Standard Deduction
The additional standard deduction for age has existed for decades and adjusts for inflation. On 2025 returns, it is $2,000 for unmarried filers and $1,600 per person for married filers. A married couple where both spouses are 65 or older gets it twice, adding $3,200 to their standard deduction for 2025.3Internal Revenue Service. Publication 554 (2025), Tax Guide for Seniors
The New $6,000 Senior Deduction
The One Big Beautiful Bill Act, signed on July 4, 2025, created an additional deduction specifically for taxpayers 65 and older. For tax years 2025 through 2028, qualifying seniors can claim $6,000 on top of the regular standard deduction and the age-based addition. A couple where both spouses are 65 or older can claim $12,000.4Internal Revenue Service. One, Big, Beautiful Bill Act: Tax Deductions for Working Americans and Seniors
The deduction phases out above $75,000 of modified adjusted gross income for single filers and $150,000 for joint filers. Unusually, it is available whether you itemize or take the standard deduction. To qualify, you must be 65 by the end of the tax year, include your Social Security number on the return, and file jointly if married.4Internal Revenue Service. One, Big, Beautiful Bill Act: Tax Deductions for Working Americans and Seniors
Stacked together in 2026, the basic standard deduction of $16,100, the age addition, and the new $6,000 deduction can shield a sizable chunk of income from federal tax for a single retiree.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
The Credit for the Elderly or the Disabled
A separate credit exists for people 65 and older, or those who retired on permanent and total disability with taxable disability income. The calculation starts with a base amount between $3,750 and $7,500 depending on filing status, subtracts certain income, and multiplies the result by 15%.5Internal Revenue Service. Publication 524 (2023), Credit for the Elderly or the Disabled The maximum is $1,125 for a joint-filing couple where both spouses qualify, and most people who claim it get less.
The income cutoffs are strict and have not been updated in years. Single filers with adjusted gross income at or above $17,500, or joint filers at or above $25,000, cannot claim it.5Internal Revenue Service. Publication 524 (2023), Credit for the Elderly or the Disabled Most retirees with any meaningful retirement income are shut out.
Medical Expenses
If you itemize, you can deduct unreimbursed medical and dental expenses that exceed 7.5% of your adjusted gross income.6Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Long-term care, hearing aids, dental work, and similar costs can accumulate quickly in later years. Because the new $6,000 senior deduction is available to itemizers too, a year with heavy medical spending can make itemizing worthwhile when it previously wasn’t.
What You Still Pay Tax On
Social Security
Social Security isn’t automatically taxable. It becomes partially taxable once your income crosses thresholds set in 1983 and never adjusted for inflation.7Office of the Law Revision Counsel. 26 U.S. Code 86 – Social Security and Tier 1 Railroad Retirement Benefits “Combined income” is your adjusted gross income plus any nontaxable interest plus half your benefits:
- Single filers between $25,000 and $34,000: up to 50% of benefits taxable.
- Single filers above $34,000: up to 85% taxable.
- Joint filers between $32,000 and $44,000: up to 50% taxable.
- Joint filers above $44,000: up to 85% taxable.
Because the thresholds are fixed, each year of inflation pulls more retirees over them. Social Security does not withhold tax automatically. You can request voluntary withholding at 7%, 10%, 12%, or 22% by submitting Form W-4V.8Internal Revenue Service. Form W-4V Voluntary Withholding Request
Retirement Account Withdrawals
Money pulled from a traditional IRA or 401(k) is taxed as ordinary income, because the contributions went in pretax.9Internal Revenue Service. Traditional IRAs Pension payments work the same way. Every dollar withdrawn raises your adjusted gross income, which can push Social Security benefits into taxable territory and lift your Medicare premiums.
Roth IRAs and Roth 401(k)s are the opposite. Qualified distributions are completely tax-free provided the account is at least five years old and you are at least 59½, disabled, or the funds are paid after your death.10Internal Revenue Service. Roth IRAs Roth accounts also carry no required distributions during the original owner’s lifetime.
Wages, Self-Employment, and Capital Gains
If you keep working past 65, your wages are taxed the same as before. Social Security and Medicare payroll taxes still come out. Self-employment income still carries self-employment tax. Working while collecting Social Security can also raise the taxable share of your benefits by lifting your combined income.
Capital gains rules do not change with age either. Long-term gains on assets held more than a year are taxed at 0%, 15%, or 20% depending on your taxable income. A large sale can push Social Security into the taxable range and trigger Medicare surcharges two years later, so the ripple effect of one transaction can run well past the gain itself.
Sales and Property Taxes
Sales tax applies to purchases at any age. There is no senior exemption. Property tax continues as long as you own the home. There is no federal break, though many states and localities offer their own relief for older homeowners through homestead exemptions, assessment freezes, or outright tax freezes. Eligibility rules on age, income, and length of residence vary widely.
Required Minimum Distributions Begin at 73
The tax deferral on a traditional IRA or 401(k) eventually ends. Starting at age 73, you must withdraw a minimum amount each year and pay income tax on it.11Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs Under the SECURE 2.0 Act, that age rises to 75 starting in 2033.
If you are still working and own 5% or less of the company, you can delay RMDs from that current employer’s plan until you actually retire. Traditional IRAs have no such delay; RMDs begin at 73 regardless of whether you are still working.11Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
Skipping an RMD is costly. The IRS imposes a 25% excise tax on the amount you should have taken out, dropping to 10% if you correct the shortfall within two years.11Internal Revenue Service. Retirement Plan and IRA Required Minimum Distributions FAQs
From age 70½, a qualified charitable distribution lets you send money straight from your IRA to an eligible charity. For 2026, the limit is $111,000 per person.12Internal Revenue Service. 2026 Amounts Relating to Retirement Plans and IRAs, Notice 2025-67 The amount counts toward your RMD but stays out of your taxable income.
IRMAA: The Medicare Surcharge That Acts Like a Tax
Medicare Part B and Part D premiums rise for higher-income beneficiaries through income-related monthly adjustment amounts, or IRMAA. The surcharge uses your tax return from two years earlier, so your 2024 income sets your 2026 premiums.
For 2026, the standard Part B premium is $202.90 a month. Modified adjusted gross income above $109,000 for single filers or $218,000 for joint filers pushes you into the surcharge tiers. At the top tier, Part B reaches $689.90 a month, and Part D carries an additional surcharge of up to $91.00.13Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
A large Roth conversion, the sale of a rental property, or a single big capital gain can spike your MAGI and raise your Medicare bill two years later. If your income has dropped since the year used for the calculation (because you retired, lost a spouse, or sold a business), you can ask the Social Security Administration for a redetermination using Form SSA-44.13Centers for Medicare & Medicaid Services. 2026 Medicare Parts A and B Premiums and Deductibles
State Taxes Still Matter
Most states don’t tax Social Security, but eight still do in some form: Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, and Vermont. Each sets its own income limits and exclusions. Colorado allows a full deduction for residents 65 and older; others phase out partial exemptions as income rises.
A few states have no income tax at all, and others exempt pensions, IRA withdrawals, or military retirement pay. The differences can run into thousands of dollars a year, and state legislatures adjust these rules often enough that it’s worth rechecking before any big retirement decision.
