TL;DR
Annuity income is taxable as ordinary income and can push you into a higher tax bracket when combined with Social Security, pensions, and RMDs. This “tax-bracket shift” reduces your net income more than expected. Use the calculator to model after-tax income across different tax scenarios.
The tax-bracket shift problem
Many retirees assume their tax rate will stay the same or decrease in retirement. But annuity income adds to other sources:
Example income sources at age 73:
- Social Security: $35,000 (partially taxable)
- Annuity payout: $25,000 (fully taxable if qualified)
- RMDs from 401k: $20,000 (fully taxable)
- Pension: $15,000 (fully taxable)
- Total taxable income: ~$70,000+
This combination can push you into the 22% or even 24% bracket even if you were in 12% during your working years.
How annuities affect your taxes
Qualified Annuities
- Entire payout is taxable as ordinary income
- Adds to taxable dollar-for-dollar
- Increases taxation of Social Security (up to 85% taxable at higher incomes)
- Can trigger IRMAA surcharges on Medicare premiums
Non-Qualified Annuities
- Only earnings portion taxable (exclusion ratio applies)
- Smaller impact on marginal tax rate
- Still can increase Social Security taxation
RMD Coordination
- RMDs begin at age 73 for most retirement accounts
- RMDs + annuity income = potential bracket creep
- Qualified annuities have their own RMD rules
Planning strategies
Laddering annuity purchases
- Buy annuities at different ages to spread income over time
- Coordinate with RMD onset
- Consider delaying annuity start until after RMDs stabilize
Mix funding sources
- Combine qualified and non-qualified annuities
- Use taxable brokerage for flexibility
- Consider Roth conversions before annuity purchases

FAQ
What are IRMAA surcharges?
Income-Related Monthly Adjustment Amounts increase Medicare Part B and D premiums when your income exceeds certain thresholds. Annuity income can trigger these surcharges, adding hundreds to your monthly Medicare costs.
Should I convert to Roth before buying an annuity?
If you expect to be in a higher tax bracket in retirement or want to minimize RMDs, Roth conversions 5+ years before annuity purchase can reduce lifetime taxes. This requires careful planning with a tax professional.
How much annuity income is too much for taxes?
There’s no fixed limit, but once your total income approaches $100,000+ (including tax-free portions), you may face marginal rates of 22-24% plus Medicare surcharges. Model your specific situation with the calculator.
