Taxes remain a part of financial life even after retirement, and the stakes can be high if you’re not paying attention. Without proper planning, retirees can unintentionally trigger higher tax bills, reduced benefits, or complications with healthcare costs. By understanding the common tax mistakes retirees make, you can better protect your retirement income and reduce financial stress over time. 

Taxes in retirement can be more complex than during working years because income often comes from a combination of sources—some taxable, some partially taxed, and some tax-free. Coordinating these effectively can have a meaningful impact on your overall financial strategy.

Mistake #1: Assuming You’ll Automatically Be in a Lower Tax Bracket 

While it’s a common belief that retirement may potentially lead to lower taxes, it’s important to remember that tax laws can change. Depending on your income sources and withdrawal strategies, you may find yourself in a similar or even higher tax bracket than during your working years. 

Distributions from traditional IRAs and 401(k)s, pension income, Social Security benefits (which may be taxable), and capital gains can all add up. Without a plan, these can push you into a higher bracket—especially after required minimum distributions (RMDs) begin. 

Avoid it: Evaluate your anticipated income sources and estimate your future tax bracket. Consider how various withdrawal strategies can help manage income levels year to year. 

Mistake #2: Ignoring Required Minimum Distributions (RMDs) 

Beginning at age 73 for many retirees, the IRS requires that you begin withdrawing a set percentage from traditional IRAs and other tax-deferred retirement accounts each year. Failing to take the full RMD can result in a significant penalty—up to 25% of the amount that should have been withdrawn. 

RMDs can also cause your taxable income to increase substantially, affecting your overall tax picture and potentially raising your Medicare premiums. 

Avoid it: Understand when your RMDs start and how much you’re required to withdraw. If you don’t need the income for expenses, you may consider withdrawal strategies earlier in retirement to reduce future RMDs. 

Mistake #3: Overlooking the Taxation of Social Security Benefits 

Many retirees are surprised to learn that a portion of their Social Security benefits may be taxable. If your combined income exceeds certain thresholds, up to 85% of your benefits may be included in your taxable income. 

This can happen more easily than expected when RMDs, investment income, or part-time work are added to the mix. 

Avoid it: Monitor your total income to avoid triggering higher taxation on Social Security. Coordinating distributions from different account types can help manage your combined income level. 

Mistake #4: Withdrawing from the Wrong Accounts First 

The order in which you withdraw funds from different accounts can significantly impact your tax burden. For instance, withdrawing only from tax-deferred accounts early in retirement could increase your taxable income, while leaving Roth accounts untouched may limit your flexibility later. 

Some retirees take withdrawals without considering how it affects their long-term income and tax profile, which may lead to larger RMDs or lost opportunities for tax efficiency. 

Avoid it: Consider a balanced withdrawal approach—drawing from taxable, tax-deferred, and tax-free accounts in a way that supports income needs and minimizes taxes. A professional can help you map out a sequence based on your situation. 

Mistake #5: Failing to Consider Medicare Premium Surcharges 

Medicare Part B and Part D premiums are based on your modified adjusted gross income (MAGI). If your income exceeds certain thresholds, you may be subject to income-related monthly adjustment amounts (IRMAA), resulting in higher premiums. 

Since income levels are reviewed two years in arrears, a high-income year now could affect your Medicare costs later. 

Avoid it: Be aware of IRMAA thresholds and manage income levels accordingly. Planning withdrawals strategically and avoiding unnecessary spikes in income can help keep premiums in check. 

Mistake #6: Overlooking State Taxes 

While much of retirement tax planning focuses on federal income taxes, state taxes can also have a significant impact. Some states tax Social Security benefits, pension income, or retirement account distributions. Others offer more retiree-friendly policies. 

Avoid it: Know your state’s tax rules and how they apply to your retirement income. If you’re considering relocating, factor in how the new location’s tax structure fits your long-term plan. 

Mistake #7: Not Adjusting Withholding or Estimated Taxes 

Retirees sometimes forget that taxes may still be owed on investment income or retirement account withdrawals. Without appropriate withholding or estimated payments, they may face an unexpected tax bill or penalties for underpayment. 

Avoid it: Review your withholding elections and consider making quarterly estimated tax payments if needed. Tracking your projected income can help you stay ahead of tax obligations throughout the year. 

Mistake #8: Missing Opportunities for Tax-Efficient Giving 

Charitable giving can be part of both a meaningful and tax-aware strategy. For retirees who must take RMDs, qualified charitable distributions (QCDs) offer a way to give to causes they care about while reducing taxable income. 

Avoid it: If charitable giving is important to you, explore how QCDs or appreciated asset donations can support your goals while offering tax advantages.
