What are the combined-income thresholds for taxing Social Security?
| Combined income (single) | Combined income (married filing jointly) | Max % of benefit taxable |
|---|---|---|
| Under $25,000 | Under $32,000 | 0% (none taxed) |
| $25,000 to $34,000 | $32,000 to $44,000 | Up to 50% |
| Over $34,000 | Over $44,000 | Up to 85% |
These federal thresholds are set by statute and are not indexed for inflation, so more retirees cross them each year. The percentage is the maximum share of your benefit that's taxable, not a tax rate. Your actual tax depends on your ordinary income bracket.
What counts as "combined income"
The IRS doesn't look at your benefit alone. It looks at a special figure sometimes called provisional income. It's built from three pieces: your adjusted gross income (wages, IRA/401(k) withdrawals, pensions, dividends), plus any nontaxable interest (like municipal-bond interest), plus one-half of your annual Social Security benefit. Add those together and compare the total to the brackets above. That's why two people receiving the same monthly check can owe very different amounts. The difference is their other income.
How can you lower the taxable share of your Social Security?
Because the tax is driven by the income around your benefit, you have more control than most retirees realize. Roth withdrawals don't count toward combined income, so income drawn from a Roth can fund your lifestyle without pushing your benefit into a higher taxable band. Timing matters too: taking IRA withdrawals or doing Roth conversions in lower-income years, and spreading out large one-time withdrawals, can keep you under a threshold. You don't need to avoid income. The aim is to arrange it so less of your Social Security gets pulled into the 85% band.

These numbers change every year
The IRMAA brackets, the standard deduction and the senior deduction are all adjusted annually, and the 2027 figures are published late in 2026. The one exception is the Social Security taxation thresholds, which have not moved since 1983 and are not expected to.

How much of my Social Security income is taxable if I am married with $50,000 of combined income?
In the worked example above, a married couple with $40,000 of Social Security and $30,000 of other income has $50,000 of combined income and $11,100 of the benefit is taxable, 28% of it. At $80,000 combined income the cap is reached and 85%, $34,000, is taxable.
Is Social Security taxed at 85%?
No. Eighty-five percent is the most of your benefit that can be included in taxable income, not the tax rate. That taxable portion is then taxed at your ordinary rate, 10% to 37% in 2026. See What Tax Rate Do You Pay on Social Security.
How much of my Social Security is taxable?
Up to 85% of your benefit can be subject to federal income tax, based on your combined income. Below $25,000 single / $32,000 married, none is taxed. In the middle band, up to 50% is taxable. Above $34,000 single / $44,000 married, up to 85% is taxable.
What counts as combined income?
Combined income equals your adjusted gross income, plus nontaxable interest (like municipal-bond interest), plus one-half of your annual Social Security benefit. The IRS compares that total to the threshold brackets to decide how much of your benefit is taxable.
How can I reduce the tax on my Social Security?
Since the tax is driven by your other income, managing it helps. Drawing from Roth accounts (which don't count toward combined income), timing IRA withdrawals or Roth conversions in lower-income years, and spreading out large withdrawals can all keep more of your benefit out of the 85% band.

What is the new $6000 tax deduction for seniors?
For tax years 2025 through 2028, each taxpayer 65 or older can deduct an extra $6,000 ($12,000 for a married couple where both qualify), whether or not they itemize. It phases out by 6% of modified AGI above $75,000 single or $150,000 joint. It does not change how much of Social Security is taxable; it lowers the income the tax is figured on.
What is the 50% rule for Social Security?
It usually refers to the spousal benefit: a spouse can receive up to 50% of the worker's full retirement age benefit if they claim at their own full retirement age. Claiming the spousal benefit earlier reduces it. For the tax on benefits, 50% is also the maximum share taxed in the middle combined-income band.
