Retirement Tax Planning: Before and During Retirement
Strategic tax moves to minimize lifetime taxes as you approach and enter retirement.
Retirement tax planning isn’t just about minimizing this year’s taxes—it’s about minimizing lifetime taxes across your entire retirement. The strategies you use before and during retirement can save tens of thousands of dollars.
Key Takeaways
- The years between retirement and age 72-75 are a key window for Roth conversions.
- Withdrawal order matters: balance current taxes vs. future RMDs and rates.
- Social Security timing and provisional income rules affect your overall tax picture.
The Retirement Tax Timeline
Understanding when different tax events occur helps you plan:
| Age/Event | Tax Impact |
|---|---|
| Retire early (before 59½) | Limited penalty-free access (72t, Roth contributions) |
| Age 59½ | Penalty-free retirement account access |
| Age 62-70 | Social Security claiming window |
| Age 65 | Medicare eligibility (IRMAA surcharges based on income) |
| Age 73-75 | Required Minimum Distributions begin |
| Lifetime | Estate planning and beneficiary considerations |
The “Golden Years” for Roth Conversions
The years between retirement and RMD age (currently 73-75) are often your lowest-income years—and your best opportunity for Roth conversions.
Why Convert in Early Retirement?
- Lower tax brackets: No salary means lower marginal rates
- Before RMDs: Convert while you control the amounts
- Before Social Security: Avoid increasing provisional income
- IRMAA planning: Manage income 2 years before Medicare Part B/D
Roth Conversion Ladder Strategy
If you retire early, you can systematically convert portions of your Traditional IRA to Roth:
- Year 1: Convert amount that fills your 12% bracket
- Year 2: Same (now Year 1’s conversion is accessible after 5 years)
- Continue until RMDs begin or accounts are converted
Example (Married, 2026):
- Standard deduction: $30,800
- 12% bracket: up to $96,950 taxable
- Convert ~$96,950 - other income each year at 12% or less
Social Security Tax Planning
How Social Security Is Taxed
Up to 85% of your Social Security benefits can be taxable, based on “provisional income” (see our guide on the Social Security tax torpedo for details):
Provisional Income = AGI + Tax-exempt interest + 50% of Social Security
| Filing Status | Provisional Income | Amount Taxable |
|---|---|---|
| Single | Under $25,000 | 0% |
| Single | $25,000–$34,000 | Up to 50% |
| Single | Over $34,000 | Up to 85% |
| MFJ | Under $32,000 | 0% |
| MFJ | $32,000–$44,000 | Up to 50% |
| MFJ | Over $44,000 | Up to 85% |
Social Security Optimization Strategies
- Delay claiming to age 70 for higher benefits and potential Roth conversion window
- Coordinate with Roth conversions — Convert before claiming to avoid taxation
- Use Roth withdrawals in retirement to avoid increasing provisional income
- Consider QCDs (age 70½+) to satisfy RMDs without increasing income
Withdrawal Sequencing
Traditional Approach
- Taxable accounts first (only gains taxed, step-up at death)
- Tax-deferred accounts (Traditional IRA, 401k) — all withdrawals taxed
- Roth accounts last (tax-free, best legacy asset)
Strategic Approach
Instead of strict sequencing, manage your tax bracket each year:
- Withdraw from tax-deferred to “fill” lower brackets
- Use Roth for amounts that would push you into higher brackets
- Consider long-term capital gains brackets for taxable sales
- Plan around IRMAA thresholds for Medicare premiums
IRMAA: The Hidden Medicare Tax
Medicare Part B and D premiums increase if your MAGI from 2 years prior exceeds thresholds:
| Single MAGI | MFJ MAGI | Monthly Part B Premium (2025) |
|---|---|---|
| ≤$106,000 | ≤$212,000 | Standard (~$185) |
| $106,001-$133,000 | $212,001-$266,000 | +$74 |
| $133,001-$167,000 | $266,001-$334,000 | +$185 |
| $167,001-$200,000 | $334,001-$400,000 | +$295 |
| Over $200,000 | Over $400,000 | +$406 |
Planning tip: Watch income in the 2 years before turning 65 to avoid IRMAA.
Required Minimum Distributions (RMDs)
When RMDs Begin
| Birth Year | RMD Starting Age |
|---|---|
| 1950 or earlier | 72 |
| 1951-1959 | 73 |
| 1960 or later | 75 |
RMD Strategies
- Aggregate RMDs across accounts — take from one IRA if easier
- Qualified Charitable Distributions — Satisfy RMD with tax-free charitable gift
- Pre-RMD Roth conversions — Reduce future RMDs by converting now
- Still working? — Can delay RMD from current employer’s 401(k)
State Tax Considerations
States tax retirement income differently:
No state income tax: Alaska, Florida, Nevada, South Dakota, Tennessee (no wage tax), Texas, Washington, Wyoming
No tax on retirement income: Illinois (retirement distributions exempt), Mississippi, Pennsylvania (some exemptions)
Relocating? Consider state tax implications, but don’t let taxes be the only factor.
Estate and Beneficiary Planning
Roth for Legacy
Roth accounts are often the best assets to leave heirs:
- No income tax for beneficiaries
- 10-year distribution rule applies (for non-spouse beneficiaries)
- Better than leaving Traditional IRA (taxable to heirs)
Stretch IRA Rules (Post-SECURE Act)
Most non-spouse beneficiaries must withdraw inherited IRAs within 10 years. Plan for:
- Potential tax bunching for beneficiaries
- Consider Roth conversions to reduce the taxable inheritance
- Life insurance as alternative legacy tool
