Charitable Giving
Strategic charitable donations can reduce your tax bill:

- Qualified Charitable Distributions: If 70½+, donate from IRA (up to $105,000)

Required Minimum Distributions (RMDs)

- Close to higher bracket threshold
- Retiring next year
- Expecting deductions next year
Accelerate Income If:
- Expect higher tax rate next year
- In low bracket this year
- Tax rates increasing in 2026
- Can offset with deductions
Prepay Deductible Expenses
If itemizing, consider prepaying:

- Medical Expenses: Schedule procedures before December 31
3. Retirement Planning Strategies
Roth Conversion Strategy
Converting traditional IRA funds to Roth can be tax-efficient in certain situations:
When to Consider Roth Conversions:
- Low-Income Years: Retirement, sabbatical, business loss
- Before RMDs: Convert before age 73 to reduce future RMDs
- Tax Rate Arbitrage: Pay taxes now at lower rate
- Estate Planning: Leave tax-free Roth to heirs
- Market Downturn: Convert when account values are lower
Roth Conversion Example:
Scenario: Retired at 65, before RMDs begin
- Traditional IRA: $500,000
- Current tax bracket: 12%
- Expected bracket at 73: 22%
Strategy:
- Convert $44,725 annually (stay in 12% bracket)
- Pay $5,367 in taxes per year
- Over 8 years, convert $357,800
- Save 10% on taxes vs. waiting for RMDs
Mega Backdoor Roth
For high earners who max out regular contributions:
- Make after-tax contributions to 401(k) (up to $69,000 total limit)
- Immediately convert to Roth 401(k) or Roth IRA
- Requires employer plan to allow after-tax contributions and in-service conversions
- Can contribute $46,000 beyond regular $23,000 limit
Catch-Up Contributions
If you're 50 or older, take advantage of catch-up contributions:
- 401(k): Extra $7,500 (total $30,500)
- IRA: Extra $1,000 (total $8,000)
- SIMPLE IRA: Extra $3,500 (total $19,500)
- HSA: Extra $1,000 (if 55+)
