Retirement Income Tax Calculator: Pensions, IRAs and Social Security
Each kind of retirement income is taxed differently, and the calculator handles all of them in one 2026 return. (IRS Publication 915)
| Income | How it's taxed in 2026 |
|---|---|
| Social Security | 0%, 50% or up to 85% taxable, by the IRS worksheet |
| Pensions, annuities | Ordinary income |
| IRA and 401(k) withdrawals, RMDs | Ordinary income |
| Qualified Roth withdrawals | Tax-free |
| Long-term gains, qualified dividends | 0%, 15% or 20% |
| Municipal bond interest | Tax-free, but it counts toward Social Security taxation |
Ordinary rates run from 10% to 37%.

Federal Income Tax Calculator for Retirees: 65-Plus Deductions Included
Three deductions stack for people 65 and older: the standard deduction ($16,100 single, $32,200 joint), an extra $2,050 for a single filer ($1,650 per married person) at 65, and the $6,000 senior deduction for 2025–2028. A married couple both over 65 can deduct up to $47,500 before paying any income tax. (IRS Rev. Proc. 2025-32)
Why your next dollar can cost more than your bracket
The calculator reports a marginal rate that includes knock-on effects. In the "tax torpedo" zone, where each extra dollar also makes Social Security taxable, a 12% bracket can behave like 22% or more. The taxable Social Security calculator charts exactly where that happens for you.

Our take: your tax rate in retirement is a choice
Unlike working years, retirement lets you decide which accounts to draw from, when to claim Social Security and when to convert to Roth. A few hours of planning each year can lower lifetime tax a lot. Start with the Roth conversion calculator and the senior deduction calculator, and add your state on the state retirement taxes guide.
