The size of your retirement savings matters, but so does how much of it you get to keep. Two retirees with the same savings and spending can pay very different amounts of tax depending on where their income comes from and when they take it. This guide goes source by source through how to reduce taxes on retirement income, then puts it together in a worked example.
Key takeaways
- Start with a map of your income sources by tax type: taxable, tax-deferred and tax-free.
- Each source has its own levers: timing for IRAs, claiming age for Social Security, which lots to sell for investments.
- The biggest savings usually come from smoothing income across years rather than letting it spike.
- Watch the thresholds that act like hidden taxes: Social Security taxation and Medicare IRMAA.
Step 1: Map your income
| Source | How it is taxed |
|---|---|
| Traditional IRA / 401(k) | Ordinary income |
| Pension | Ordinary income (minus any after-tax basis) |
| Social Security | 0% to 85% taxable, depending on other income |
| Brokerage account | Only gains and dividends, often at 0% or 15% |
| Roth IRA / Roth 401(k) | Tax-free if qualified |
| HSA (for medical costs) | Tax-free |
Step 2: Reduce tax source by source
Traditional IRAs and 401(k)s
- Withdraw or convert to Roth in low-income years to fill the 10% and 12% brackets.
- Reduce the balance before RMDs begin, so forced withdrawals are smaller later.
- From 70½, give to charity with qualified charitable distributions (up to $111,000 in 2026).
Social Security
- Delaying your claim gives a larger check and leaves more low-income years for conversions.
- Keeping other income lower in a given year keeps more of your benefit untaxed. See how Social Security is taxed.
Pensions
- Choose your payout option and withholding carefully, and check your state’s rules. See how to pay less tax on your pension.
Taxable investments
- Sell high-basis lots first and realise gains in years you are under the 0% capital gains ceiling ($98,900 taxable income for couples in 2026).
- Harvest losses to offset gains and up to $3,000 of ordinary income. See capital gains in retirement.
Roth accounts
- Use Roth money in years when an extra taxable dollar would cross a bracket, Social Security or IRMAA threshold. See tax-free income strategies.
Step 3: Use your deductions
For 2026, the standard deduction is $32,200 for married couples and $16,100 for single filers, plus extra for those 65 and over. From 2025 through 2028, people 65 and over can also claim an additional deduction of up to $6,000 each, which phases out at higher incomes. Make sure your income plan uses this room every year rather than leaving it empty.
A worked example
A married couple, both 66, need $90,000 a year. They have $900,000 in traditional IRAs, $200,000 in a brokerage account and $100,000 in Roth IRAs, and have not yet claimed Social Security.
- Plan A, IRA only: they take $90,000 from IRAs each year until 70, then claim Social Security. Their IRAs shrink, but the withdrawals stay inside the 12% bracket after the standard and senior deductions.
- Plan B, no plan: they claim Social Security at 66, spend from the brokerage account and leave the IRA untouched. Taxes look low now, but at 75 large RMDs on top of Social Security push them into the 22% bracket, make 85% of their benefits taxable and risk IRMAA.
Plan A usually produces a lower lifetime tax bill and larger Social Security checks. The details depend on the numbers, which is why running your own projection matters. See tax-efficient withdrawal strategies.
Step 4: Review every year
Tax law, markets and your spending all change. Each autumn, project your income for the year, check where it lands against key thresholds, and adjust conversions or withdrawals before December 31.
The bottom line
Reducing taxes on retirement income isn’t about one clever trick. It is about knowing how each source is taxed and drawing on them in the right mix, year after year.
