I’m looking for retirement and tax experts who can explain how retirees can quickly assess whether they may be paying more tax than necessary on withdrawals from 401(k)s, traditional IRAs and other retirement accounts. The article will focus on practical warning signs and withdrawal strategies retirees can review with a tax or financial professional. 1. What is the simplest way for a retiree to check whether they may be paying more tax than necessary on retirement-account withdrawals? 2. What are the most common mistakes you see retirees make when withdrawing money from traditional IRAs, 401(k)s and other taxable retirement accounts? 3. How can taking a large withdrawal in a single year push a retiree into a higher marginal tax bracket or otherwise increase their tax bill? 4. How should retirees think about the mix of taxable, tax-deferred and tax-free accounts when deciding where to withdraw money from each year? 5. How can retirement withdrawals affect the taxation of Social Security benefits, and what should retirees watch for? 6. Can retirement withdrawals also increase Medicare premiums through IRMAA? How does that work and what should retirees consider before making a large withdrawal? 7. What role do required minimum distributions play in withdrawal planning, and are there steps retirees can take before RMD age to potentially reduce future tax bills? 8. When might Roth conversions help reduce lifetime taxes, and when could converting actually result in an unnecessarily large current-year tax bill? 9. Can you provide a simple numerical example of two retirees needing the same amount of spending money but owing different amounts in taxes because of how or when they take their withdrawals? 10. What tax numbers or documents should retirees review each year to perform a quick “retirement withdrawal tax check,” and when should they bring in a CPA, tax attorney or financial planner?
