When it comes to drawing down your retirement savings, planning is everything — without it, you might face surprise tax bills that could put a dent in your hard-earned savings.
Dave Ramsey warns nearly 50% of Americans are making 1 big Social Security mistake — here’s how to fix it ASAP
Here are five ways to ensure that you're prepared when it comes to how your retirement income is taxed.
Social Security
A survey in 2024 conducted by Nationwide Financial found that 50% of respondents believed that Social Security benefits were tax-free (1).
If you're under the impression that you won't ever have to pay taxes on Social Security benefits, here's your wake-up call: Depending on your income, you may have to pay federal income taxes on a portion of your Social Security benefits.
The IRS calculates what portion of Social Security benefits are taxable by adding one-half of your benefits, plus all of your other income, including tax-exempt interest (2). If this total, your "combined income," is greater than the base amount for your filing status, you may owe taxes on your benefits.
The base amount for single people, heads of household or qualifying surviving spouses, is $25,000; the base amount for married couples filing jointly is $32,000.
If you're over these thresholds, how much tax could you have to pay?
Fifty percent of your benefits could be taxable if you're filing single, head of household or are a qualifying surviving spouse, and your combined income is between $25,000 to $34,000; for married couples filing jointly, it's $32,000 to $44,000 (3).
And, up to 85% of your benefits could be taxable if you're filing single, head of household or are a qualifying surviving spouse, and your combined income is more than $34,000; for married couples filing jointly, it's $44,000 income.
Tax-deferred retirement accounts such as 401(k)s and IRAs demand that you take required minimum distributions (RMDs), which are minimum amounts you have to withdraw from your retirement accounts every year, beginning at age 73 (4).
According to a report from Bloomberg, having a mix of account types allows for more flexibility, since Roth withdrawals are not subject to RMDs, and are tax-free as long as the account has been open at least five years (5).
If your future RMDs are likely to inflate your tax bill, you could consider converting a portion of your 401(k) or traditional IRA to a Roth IRA, though you will have to pay tax on that portion in the tax year you're converting it.
Timing Roth conversions
According to Bloomberg, waiting to make Roth conversions until after age 63 can have an unpleasant consequence: higher Medicare costs.
Since Medicare Part B and D premiums are calculated based on income from two years prior, the Bloomberg report says, a substantial Roth conversion "could trigger an IRMAA (income-related monthly adjustment amount) surcharge on those premiums."
Medicare premiums are calculated annually, however, and according to the report, for some retirees in low-income years, it can make sense to make larger conversions "despite the tax hit."
"The long-term benefit of that conversion may outweigh the short-term pain of Medicare premiums, which are a one-year thing," Tim Steffen, director of advanced planning for Baird Private Wealth Management, told Bloomberg.
Tax-loss harvesting
If you have investments outside of tax-advantaged retirement accounts, a strategy to offset your capital gains, or possibly your taxable income, is tax-loss harvesting.
If you sell an investment at a capital loss, you may be able to deduct this capital loss from your capital gains, reducing your capital gains taxes. If your capital losses in a year are greater than your capital gains, you can deduct up to $3,000 ($1,500 if married filing separately) from your annual income (6). If your capital losses are more than the limit, you can carry forward the loss and apply it to later years.
With the tax-loss harvesting strategy, experts recommend replacing the investments you've sold with similar assets, but not by repurchasing the same asset, which can trigger the IRS wash-sale rule. This rule says you cannot buy back the same or a "substantially identical" security soon after, while claiming a capital loss (7).
Bloomberg notes that this strategy "may be less useful for investors expecting higher tax rates later or those already able to realize gains at a 0% rate."
Consider your heirs
Finally, consider what the tax implications will be for your heirs if you are leaving them retirement savings accounts.
According to Bloomberg, "most non-spouse heirs must empty inherited IRAs within 10 years," which can have a big impact on your heirs' tax bills, especially if they are in their higher-earning years.
The report notes that while non-spouse beneficiaries of Roth accounts must still withdraw funds within a similar timeframe, "distributions will be tax-free," leaving your heirs with less of a tax headache when it comes to their inheritance.
Four leading AI models discuss this article
"Retirement tax planning is currently focused on optimizing for today's brackets, while failing to hedge against the systemic risk of future tax hikes necessitated by long-term fiscal deficits."
The article focuses on tax efficiency, but ignores the 'tax bomb' risk inherent in the current fiscal trajectory. With the U.S. debt-to-GDP ratio climbing, the assumption that tax rates will remain stable is dangerous. While Roth conversions and loss harvesting are sound tactical moves, they are secondary to the macro risk of rising marginal tax rates. Investors should prioritize tax-diversification, but beware of over-optimizing for current brackets. The real risk isn't just a surprise bill at 73; it is the potential for legislative changes to RMD rules or the taxation of Roth accounts if the government seeks to close the deficit gap. Tactical planning is necessary, but don't mistake it for a permanent tax shield.
Excessive focus on tax-minimization often leads investors to hold sub-optimal, high-fee, or low-growth assets just for their tax status, which can destroy more wealth than the taxes themselves.
"N/A"

"The article recycles standard tax guidance without evidence that these 'mistakes' are widespread enough or costly enough to warrant the alarm-bell framing."
This is personal finance guidance, not market-moving news. The article restates well-known tax code (Social Security taxation, RMD rules, wash-sale restrictions) that hasn't changed materially. The 50% Social Security misconception is real but hardly new—tax advisors have flagged this for decades. The Roth conversion timing trap around Medicare IRMAA is legitimate and underexplored in retail media, but it's a niche optimization for high-net-worth retirees, not systemic risk. Tax-loss harvesting advice is generic. The article offers no data on prevalence of these mistakes or their aggregate dollar impact, making it impossible to assess whether this represents a meaningful behavioral gap or just standard tax-planning content.
If half of Americans genuinely don't know Social Security is taxable, that's not a 'mistake to avoid'—it's a knowledge gap that tax software and advisors already handle at filing time. The article conflates planning failures with ignorance that gets corrected anyway, overstating urgency.
"The biggest determinants of after-tax retirement outcomes are policy changes and longevity, not a generic five-step checklist."
Useful primer but glosses over critical risks and constraints. It treats five tax moves as broadly applicable, yet real-world outcomes hinge on state tax treatment of Social Security, Medicare IRMAA triggers, and the 10‑year inherited-IRA rule. It omits that tax-loss harvesting primarily applies to taxable accounts (not inside IRAs), and it lacks scenario modeling around longevity, health, and potential policy shifts that could alter tax brackets. Without illustrating the tradeoffs and budget impact, readers may misallocate assets or overestimate the net benefit of these strategies.
But for many retirees, optimizing withdrawals, Roth conversions, and tax-loss harvesting often materially improves after-tax cash flow and heirs’ outcomes in practice; policy volatility is uncertain and may not erase these benefits.
"Prioritizing tax-efficiency over asset-growth potential often leads to lower total wealth accumulation."
Claude is right that this is mostly retail filler, but Gemini misses the second-order effect: behavioral risk. By obsessing over tax-minimization, investors often drift into 'tax-efficient' but stagnant assets like municipal bonds or low-yield dividend stocks, ignoring the massive opportunity cost of equity growth. Over-optimizing for a hypothetical future tax hike often results in a lower net-worth outcome than simply paying the tax on higher-growth, tax-inefficient assets today. The tax tail is wagging the investment dog.

"Tax optimization and growth allocation are orthogonal problems; the article fails on both, but the sequencing error matters more than the philosophical one."
Gemini's behavioral risk point is sharp, but it conflates two separate failures: (1) tax-obsession causing asset-class drift, and (2) underweighting growth. The real issue is *sequencing*—retirees should optimize tax-efficiently *within* their target allocation, not choose between 'tax-efficient stagnation' or 'ignore taxes entirely.' ChatGPT's omission of state tax treatment and IRMAA cliffs is the bigger gap here; those can swing $50k+ annually for high-income retirees, dwarfing most harvesting gains.
"Policy cliffs from state taxes and IRMAA can dwarf the gains from tax-minimization, so sequencing to optimize net after-tax outcomes across credible policy scenarios matters more than chasing tax-efficient but low-growth assets."
Responding to Gemini: The behavioral risk is real, but the bigger, underappreciated swing factor is policy cliffs—not just tax rates. State taxes and Medicare IRMAA triggers can swing $50k+ annually for high earners, dwarfing harvesting gains or Roth conversions in many paths. Instead of chasing 'tax-efficient' assets, retirees should bake sequencing into the plan—optimize withdrawals and conversions where net after-tax payoff is highest across credible policy scenarios.
