401(k) Tax Bracket Smoothing: Save on 12% Rates Annually

Married couples can convert approximately $133,000 annually from traditional 401(k) accounts to Roth at a 12% tax rate, minimizing effective taxes to about 9% before reaching the 22% bracket. Retirees facing large distributions may find effective marginal tax rates near 40% when RMDs and Social Security taxation converge at age 73. For a couple starting with $1.5 million in 401(k)s, failing to use bracket smoothing could inflate their RMD to around $107,000, alongside approximately $80,000 in delayed Social Security benefits, increasing gross income to over $187,000. Implementing these strategies is essential to manage retirement tax liabilities effectively.
