Many retirees are surprised to learn that Social Security benefits can be subject to federal income tax. Whether yours are taxed, and how much, depends on your other income. The rules have been in place for decades, and in 2025 there was widespread discussion of “no tax on Social Security.” The One Big Beautiful Bill Act (OBBBA) did not actually eliminate the tax on benefits, but it did create a new deduction for people 65 and older that reduces or eliminates the tax for many retirees. This guide answers the question “is Social Security taxable?” and explains how to estimate and manage the tax.

The short answer
Social Security benefits are partly taxable for some people and tax-free for others. If your total income is modest, none of your benefits may be taxable. As income rises, up to 50% and then up to 85% of benefits can be included in your taxable income. No one pays federal income tax on more than 85% of their benefits.
How provisional income works
The IRS uses a measure called provisional income (sometimes called combined income) to decide how much of your benefits is taxable:
Provisional income = adjusted gross income (not counting Social Security) + tax-exempt interest + 50% of your Social Security benefits
Tax-exempt municipal bond interest counts even though it is not taxed itself.
The thresholds
| Filing status | Up to 50% taxable | Up to 85% taxable |
|---|---|---|
| Single, head of household | Provisional income $25,000 to $34,000 | Over $34,000 |
| Married filing jointly | $32,000 to $44,000 | Over $44,000 |
| Married filing separately, lived with spouse | n/a | Up to 85% from the first dollar |
These thresholds are set in law and are not adjusted for inflation. As a result, a growing share of retirees owe tax on benefits over time as incomes and cost-of-living adjustments rise.
A worked example
A single retiree receives $24,000 a year in Social Security and $20,000 of pension income, with no other income.
- Half of benefits: $12,000.
- Provisional income: $20,000 + $12,000 = $32,000.
- That is $7,000 above the $25,000 threshold and below $34,000, so the 50% tier applies.
- Taxable benefits: 50% of $7,000 = $3,500 (the lesser of that amount or half of benefits).
So $3,500 of the $24,000 in benefits is added to taxable income. Whether this retiree actually owes tax depends on deductions. With the 2026 standard deduction of $16,100, the additional standard deduction for age, and the new senior deduction of up to $6,000, taxable income of $23,500 ($20,000 pension plus $3,500 of benefits) could be largely or fully offset.
The calculation becomes more complex in the 85% tier. IRS Publication 915 and the worksheet in the Form 1040 instructions walk through it, and tax software handles it automatically.
What the 2025 tax law changed
OBBBA, signed July 4, 2025, did not change the formula for taxing Social Security. Provisional income, the thresholds, and the 50% and 85% tiers all remain.
Instead, for tax years 2025 through 2028, it created a new senior deduction of up to $6,000 for each taxpayer 65 or older ($12,000 for a married couple where both qualify). Key points:
- It is available whether or not you itemize and is claimed on Schedule 1-A.
- It phases out by 6% of modified adjusted gross income above $75,000 for single filers and $150,000 for joint filers.
- You do not need to receive Social Security to qualify.
For many middle-income retirees, the senior deduction combined with the standard deduction means that even though part of their benefits is technically taxable, they owe little or no federal income tax. Higher-income retirees may receive a reduced deduction or none.
State taxes on Social Security
Most states do not tax Social Security benefits, and several that once did have repealed or phased out their taxes in recent years. A small number of states still tax benefits for some residents, often with income-based exemptions. Check your state’s revenue department for current rules, especially if you are considering relocating in retirement.
How to pay tax on benefits
If your benefits are taxable, you can avoid a large bill at filing time by:
- Requesting voluntary withholding from Social Security using Form W-4V. You can choose 7%, 10%, 12%, or 22% of each payment.
- Increasing withholding from a pension or IRA distributions.
- Making quarterly estimated tax payments using Form 1040-ES.
Each January, the Social Security Administration sends Form SSA-1099, showing total benefits paid in the prior year. You will use it to complete your return.
Ways to reduce tax on your benefits
Because provisional income drives the calculation, strategies that lower other income can reduce the share of benefits that is taxable:
Draw from Roth accounts
Qualified Roth IRA and Roth 401(k) withdrawals are not included in provisional income. Having a mix of Roth and traditional savings gives you flexibility to control income in retirement.
Use qualified charitable distributions
If you are 70½ or older and give to charity, a qualified charitable distribution directly from your IRA counts toward required minimum distributions but is excluded from income, keeping provisional income lower.
Time Roth conversions carefully
Converting traditional IRA money to Roth raises income in the year of conversion, which can make more of your benefits taxable that year. Some retirees convert in the years after retirement but before claiming Social Security, when income is lower.
Manage capital gains and withdrawals
Realizing large capital gains or taking a big IRA withdrawal in one year can push provisional income over a threshold. Spreading them across years may reduce the total tax.
Consider when to claim
Delaying Social Security while living on other savings can lower taxable income in your early retirement years and allow Roth conversions at lower rates. It also increases your monthly benefit permanently. The right claiming age depends on health, other income, and marital status.
Social Security and Medicare premiums
Higher income can also raise your Medicare Part B and Part D premiums through income-related monthly adjustment amounts (IRMAA), which are based on modified adjusted gross income from two years earlier. Medicare premiums are often deducted from Social Security checks, so planning for IRMAA and taxes together gives a clearer picture of your net benefit.
The 2026 COLA
According to the Social Security Administration, benefits increased by a 2.8% cost-of-living adjustment for 2026. Because the provisional income thresholds do not rise with inflation, COLAs can gradually push more retirees into taxable territory even if their real income has not changed.
Frequently Asked Questions
Did the new tax law eliminate tax on Social Security?
No. The One Big Beautiful Bill Act kept the existing rules for taxing benefits but added a temporary deduction of up to $6,000 per person for taxpayers 65 and older from 2025 through 2028, which reduces or eliminates the tax for many retirees.
What percentage of Social Security is taxable?
Between 0% and 85%, depending on your provisional income and filing status.
Is Social Security taxable if it is my only income?
Generally no. If Social Security is your only income, half of your benefits alone is usually below the $25,000 or $32,000 thresholds, so none of it is taxable.
Are Social Security disability benefits taxed the same way?
Yes. SSDI benefits follow the same provisional income rules. Supplemental Security Income (SSI) is not taxable.
How do I have tax withheld from Social Security?
Submit Form W-4V to the Social Security Administration and choose a withholding rate of 7%, 10%, 12%, or 22%.
Do I have to file a tax return if I only get Social Security?
Often not, if your benefits are not taxable and you have no other income requiring a return. Check the IRS filing requirements for your situation.
The bottom line
Social Security is taxable for some retirees and not others. Up to 85% of benefits can be included in income once provisional income exceeds fixed thresholds of $25,000 for single filers and $32,000 for joint filers. The 2025 law did not repeal that tax, but its $6,000 senior deduction means many retirees will owe less or nothing for 2025 through 2028. Managing your other income sources is the most effective way to control how much of your benefits are taxed.
