Retirement Tax Planning Guide 2026: Strategies, Brackets & Withdrawals
A research-backed guide by TheTaxCalc Editorial Team — data verified against IRS & state sources, updated for the 2026 tax year
Complete retirement tax planning guide for 2026. Learn tax strategies for retirees, 401(k) withdrawal rules, Social Security taxation, RMDs, and Roth conversions to minimize your tax burden.
Retirement changes where your income comes from — not whether it gets taxed. Pensions, Social Security, 401(k) withdrawals, and investment gains each follow different rules. This 2026 guide covers all the levers, with exact numbers you can plan around.
The Four Income Streams and How They're Taxed
| Income source | 2026 federal tax treatment |
|---|---|
| Traditional 401(k)/IRA withdrawals | Ordinary income (10%–37%) |
| Roth withdrawals | $0 (if 59½ + 5-year account) |
| Social Security | 0%, 50%, or 85% taxable depending on combined income |
| Pension | Ordinary income (mostly) |
| Investment gains/dividends | 0%, 15%, or 20% + possible 3.8% NIIT |
Social Security Taxation: The Two Thresholds
Social Security becomes taxable as your provisional income (AGI + tax-exempt interest + half of Social Security) crosses:
| Provisional income (single) | Taxable portion |
|---|---|
| Under $25,000 | 0% |
| $25,000–$34,000 | Up to 50% |
| Over $34,000 | Up to 85% |
The married thresholds are $32,000 and $44,000. Note: "up to" — the IRS formula usually lands somewhere between 50% and 85% in practice.
The stealth tax: one extra dollar of 401(k) withdrawal can make an extra 85 cents of Social Security taxable. Effective marginal rates in the $25,000–$34,000 band can reach 40%+ for what looks like a 22%-bracket retiree.
The 2026 Tax Year Baseline
| Figure | 2026 amount |
|---|---|
| Standard deduction (65+, single) | $16,100 + $6,000 OBBBA senior deduction |
| Married standard deduction (65+ each) | $32,200 + $6,000 per spouse |
| Roth IRA contribution limit (50+) | $8,500 |
| 401(k) limit (50+) | $30,500 |
The OBBBA $6,000 senior deduction (2025–2028) is a genuine planning tool: a single 65+ retiree with no other deductions pays $0 federal tax on their first $22,100 of ordinary income in 2026.
State Taxation of Retirement Income Varies Wildly
- Fully exempt states: Illinois does not tax 401(k), IRA, pension, or Social Security distributions at all. Mississippi and Pennsylvania also exempt retirement income broadly.
- Zero-income-tax states: Florida, Texas, Nevada, Washington, Tennessee, Wyoming, South Dakota, Alaska, New Hampshire — every retirement dollar skips state tax.
- Social Security: most states do not tax it.

The Roth Conversion Window (Ages 60–73)
Between retirement and RMDs, you control your taxable income — the perfect Roth conversion window:
- Fill the 0% room first — standard deduction + senior deduction = $22,100 tax-free (single, 65+).
- Fill the 10% and 12% brackets with conversions — cheap permanent tax relief.
- Watch the IRMAA cliff — Medicare premiums are set by your MAGI from two years prior; large conversions can cost more in premiums than they save in tax.
- Conversions before RMDs shrink future RMDs, cutting both the RMD tax and the Medicare surcharge later.
Withdrawal Ordering That Minimizes Tax
The tax-efficient sequence for most retirees:
- Required distributions (RMDs first — the 25% penalty for missing one is brutal)
- Taxable brokerage — long-term gains at 0%/15% (0% rate applies up to roughly $51,600 of taxable income for single filers in 2026)
- Roth withdrawals — tax-free, no RMDs
- Traditional (pre-tax) last — every dollar is ordinary income
But run the numbers against Social Security taxation — sometimes a traditional withdrawal in a low year beats selling appreciated stock.
Frequently Asked Questions
How can I pay $0 tax in retirement (legally)?
Single 65+ with $22,100 of ordinary income (standard + senior deduction), plus long-term gains within the 0% bracket, plus Roth withdrawals, plus Social Security below the $25,000 threshold — roughly $70,000+ of retirement income with $0 federal tax.
At what age do I stop paying taxes on retirement income?
Never — age only removes the 10% early-withdrawal penalty at 59½. Income tax continues for life.
Are Roth conversions worth it?
Yes if you expect future brackets higher (RMDs + IRMAA) and can convert within the 12%–24% brackets. Use our 401(k) calculator to project balances and RMD sizes.
Do I pay state taxes on my pension?
Depends on the state — Illinois exempts it, Mississippi and Pennsylvania mostly exempt it, most other states tax it as ordinary income. Check your state page: California, New York, Florida, or any of our 50 state calculators.
