Common Tax-Exempt Sources

Municipal bond interest is generally exempt from federal income tax Qualified Roth IRA and Roth 401(k) distributions are tax-free Life insurance death benefits paid to beneficiaries are income-tax-free HSA withdrawals for qualified medical expenses are completely tax-free

Common Tax-Deferred Sources

Traditional IRA and 401(k) contributions grow tax-deferred until withdrawal Annuity gains are tax-deferred until you begin taking distributions Series I and EE savings bond interest can be deferred until redemption 1031 like-kind exchanges defer real estate capital gains into replacement property

When Each Approach Works Best

Tax deferral wins when you are in a high bracket now and expect a lower one later Tax-exempt wins when you expect rates to rise or income to be higher in retirement Employer matches on pre-tax contributions are effectively free money — capture them Building a tax-free legacy for heirs through Roth conversions favors tax-exempt accounts

Required Minimum Distributions

Traditional IRAs and 401(k)s require RMDs starting at age 73 (SECURE 2.0) RMDs are calculated by dividing account balance by an IRS life expectancy factor Failure to take RMDs triggers a 25% excise tax on the shortfall amount Roth IRAs have no RMDs during the owner's lifetime — a significant planning advantage

Impact on Medicare Premiums and AMT

Tax-deferred withdrawals increase MAGI and can trigger higher Medicare Part B/D premiums IRMAA surcharges begin at $106,000 single / $212,000 MFJ (2025 thresholds) Roth distributions and municipal bond interest do not count toward IRMAA calculations Some municipal bonds (private activity bonds) generate phantom income under the AMT

Estate Planning and Key Takeaways

Inherited traditional IRAs require full distribution within 10 years for most beneficiaries Inherited Roth IRAs follow the 10-year rule but distributions remain tax-free Converting to Roth before death reduces the taxable burden passed to heirs Compare your current marginal rate to your expected retirement rate when choosing
