Taxes can take a bigger bite out of retirement savings than many baby boomers expect. Decades of hard work and careful saving can be undermined by overlooked tax traps that quietly erode wealth. The rules around retirement accounts, Social Security, and Medicare are complex, and the implications for taxes can be surprising. If you’re a baby boomer approaching or in retirement, it’s crucial to understand how your decisions now can impact your tax bill later. Knowing the most common tax traps for baby boomers can help you keep more of your hard-earned money and reduce financial stress in your golden years.
1. Underestimating Required Minimum Distributions (RMDs)
One of the biggest tax traps baby boomers face is not planning for required minimum distributions (RMDs) from traditional IRAs and 401(k)s. Once you reach age 73, you must start withdrawing a minimum amount each year, whether you need the money or not. These withdrawals are taxed as regular income, which can push you into a higher tax bracket or even trigger additional taxes on Social Security benefits.
If you forget to take your RMD, the IRS imposes a hefty penalty—up to 25% of the amount you should have withdrawn. It’s important to factor RMDs into your retirement income strategy well before you reach the age threshold. Consider consulting a financial advisor to develop a withdrawal plan that minimizes your tax burden over time.
2. Ignoring the Taxation of Social Security Benefits
Many baby boomers are surprised to learn that Social Security benefits can be taxable. If your combined income—including half your Social Security benefits, plus all other income—exceeds certain thresholds, up to 85% of your benefits may be subject to federal income tax. For individuals, this threshold starts at $25,000; for married couples filing jointly, it’s $32,000. These limits haven’t changed in decades, so more retirees get hit with this tax trap every year.
Strategic withdrawals from retirement accounts can help you manage your taxable income and possibly reduce how much of your Social Security is taxed. It’s wise to run the numbers before taking large withdrawals or starting benefits to avoid unnecessary surprises at tax time.
3. Overlooking Capital Gains in Retirement
Many baby boomers focus on income taxes but forget about capital gains taxes when selling investments. If you’ve invested in stocks, mutual funds, or real estate outside of retirement accounts, you could owe taxes on the profits when you sell. Long-term capital gains are generally taxed at lower rates, but selling large amounts in a single year can increase your overall tax bracket and cause other tax ripple effects.
Timing matters. Selling investments gradually or during years when your income is lower can help you pay less in capital gains tax. Don’t forget to factor in state taxes, which can be significant depending on where you live.
4. Not Planning for the Medicare IRMAA Surcharge
The Income-Related Monthly Adjustment Amount (IRMAA) is a hidden tax trap baby boomers often overlook. If your modified adjusted gross income (MAGI) exceeds certain thresholds, you’ll pay higher premiums for Medicare Part B and Part D. For 2024, the IRMAA surcharge kicks in for individuals with MAGI above $103,000 and couples above $206,000.
This surcharge can add thousands of dollars to your healthcare costs each year. Large IRA withdrawals, capital gains, or even the sale of a home can push you over the limit. To avoid this tax trap, coordinate withdrawals and income planning with Medicare premium thresholds in mind.
5. Forgetting State Taxes on Retirement Income
Not all states tax retirement income the same way. Some states fully tax pensions, Social Security, and IRA withdrawals, while others exempt them or offer partial relief. Moving to a new state for retirement without researching the tax implications can lead to an unpleasant surprise.
Before you relocate, review each state’s rules on retirement income taxation. States like Florida and Texas have no state income tax, while others, like California and New York, are less forgiving.
6. Missing Roth Conversion Opportunities
Roth conversions let you move money from a traditional IRA or 401(k) to a Roth IRA, paying taxes on the converted amount now in exchange for tax-free withdrawals later. Many baby boomers miss out on this strategy, either because they don’t know about it or fear the immediate tax hit. But for those in a lower tax bracket—especially before RMDs begin or Social Security starts—a Roth conversion can be a powerful way to avoid future tax traps.
Careful planning is key. Converting too much in one year can bump you into a higher bracket or cause other taxes to increase. Spreading conversions over several years and coordinating with your overall tax plan can help minimize the pain.
Smart Moves to Avoid Common Tax Traps for Baby Boomers
Tax traps for baby boomers can be costly, but they’re not unavoidable. Proactive planning—starting years before retirement—can help you avoid penalties, reduce taxes on Social Security, and keep more of your savings. Work with a knowledgeable financial advisor or tax professional who understands the unique challenges baby boomers face. Stay informed about changes in tax laws and adjust your strategy as needed.
