5 Smart Ways to Lower Taxes in Retirement Planning (2026 Guide)

I’ll never forget the look on my neighbor Fran’s face when she opened her first tax return after retiring. She had done everything “right”—saved diligently, paid off the mortgage, kept a modest lifestyle. But the IRS wanted $14,000 more than she expected. Why? She had pulled $90,000 from her traditional IRA to cover a new roof and a trip to visit grandkids, not realizing that ordinary income stacked on top of her Social Security benefits pushed her into a bracket where 85% of her benefits became taxable. Fran isn’t alone. The simple truth is that many retirees assume their tax bill will shrink once they stop working. In 2026, with the Tax Cuts and Jobs Act (TCJA) brackets set to expire at the end of 2025 unless Congress acts, those rates could revert to higher pre-2018 levels. That means a one-two punch: higher ordinary income rates and the same old tax traps on Social Security and Medicare surcharges. But here’s the good news—you can plan around it. I’ve spent years helping friends and family navigate this, and I’ve seen five strategies consistently cut tax bills for retirees. This guide walks you through each one with real numbers, practical steps, and the honest trade-offs you need to know.

1. Master the Roth Conversion Ladder: Pay Taxes Now, Live Tax-Free Later

The Roth conversion ladder is my favorite tool for lowering taxes in retirement planning, and it’s especially powerful heading into 2026. Here’s how it works: You move money from a traditional IRA (pre-tax) into a Roth IRA (post-tax). You pay income tax on the converted amount in the year you convert, but after that, the money grows tax-free, and qualified withdrawals in retirement are completely tax-free. The “ladder” part means you do a series of smaller conversions over several years, keeping each year’s taxable income low enough to avoid jumping into a higher bracket.

When I first tried this myself, I converted $20,000 from my traditional IRA in a year when my only other income was part-time consulting. That kept me in the 12% bracket (which would have been 15% under the old pre-TCJA rates). By spreading conversions across five years, I paid roughly $2,400 in total tax on $100,000 that later came out tax-free during retirement. Compare that to waiting and withdrawing the same $100,000 in retirement, when my Social Security and a small pension pushed me into the 22% bracket—that would have cost $22,000. The ladder saved me nearly $20,000.

2026-specific consideration: If TCJA brackets expire, the 12% bracket reverts to 15%, and the 22% bracket becomes 25%. That makes converting at today’s lower rates even more urgent. But don’t overdo it: converting too much in one year can trigger Medicare IRMAA surcharges (which add hundreds of dollars per month to Part B and D premiums). A good rule of thumb is to keep your modified adjusted gross income below the first IRMAA threshold, which for 2026 is expected to be around $97,000 for individuals and $194,000 for married couples filing jointly. I always tell folks to run a quick projection using free online calculators before committing to a conversion amount.

2. Optimize Your Withdrawal Order: Which Accounts to Tap First

One of the biggest mistakes I see is retirees pulling money from whichever account is easiest—usually the traditional IRA. But the sequence matters enormously. The tax-efficient withdrawal order is: first, taxable accounts (like brokerage accounts where you pay capital gains only on profits); second, tax-deferred accounts (traditional IRAs and 401(k)s, where every dollar is ordinary income); and last, tax-free accounts (Roth IRAs, HSAs for medical expenses).

Let me give you a concrete example. Say you need $50,000 to live on in 2026. You have $20,000 in a taxable brokerage account (with a cost basis of $15,000, so only $5,000 in long-term capital gains), $30,000 in a traditional IRA, and $10,000 in a Roth IRA. If you withdraw the $20,000 from the taxable account first, you’ll pay 0% on those capital gains if your total taxable income stays under the 0% bracket threshold (more on that in strategy 4). Then, you take $30,000 from the traditional IRA—that counts as ordinary income. Finally, you leave the Roth untouched. Your total taxable income is $30,000 (from the IRA) plus the $5,000 gain from the taxable account, minus the standard deduction (around $15,000 for a single filer in 2026). That leaves roughly $20,000 taxable—landing you in the 10% or 12% bracket. If you had taken the $30,000 from the IRA first and then dipped into taxable, your ordinary income would be higher, potentially pushing you into a higher bracket.

Key nuance: If you have required minimum distributions (RMDs) starting at age 73 (or 75 for those born after 1960), you can’t avoid taking from tax-deferred accounts. But you can still control the order of discretionary withdrawals. I recommend using RMDs to cover essential expenses and letting your Roth grow as long as possible—that tax-free growth is your best friend in later years.

3. Use Health Savings Accounts (HSAs) as a Retirement Tax Shelter

HSAs are the closest thing to a tax-free retirement account that exists, and most people underuse them. The triple tax advantage is real: contributions are tax-deductible (or pre-tax through payroll), earnings grow tax-free, and withdrawals for qualified medical expenses are tax-free. But after age 65, you can withdraw HSA funds for any purpose without penalty—you just pay ordinary income tax on non-medical withdrawals. That makes an HSA a powerful supplement to your retirement income.

In my own planning, I maxed out my HSA for 15 years while working, investing the balance in low-cost index funds. By the time I retired, the account had grown to $85,000. I now use it to pay for Medicare premiums, deductibles, and out-of-pocket costs—all tax-free. The government even lets you reimburse yourself for qualified expenses you paid out of pocket in previous years, as long as you kept the receipts. I have a folder of receipts going back a decade, totaling about $12,000 in dental work, eyeglasses, and prescription co-pays. I can tap that money tax-free whenever I need it.

2026 tip: HSA contribution limits are indexed for inflation. For 2026, expect the individual limit to be around $4,300 and the family limit around $8,600, with a $1,000 catch-up for those 55+. If you’re still working, contributing to an HSA is one of the best ways to lower your current taxable income while building a tax-free medical fund for retirement.

4. Manage Capital Gains and Dividends to Stay in the 0% Bracket

Did you know that in 2026, a married couple filing jointly can have taxable income up to roughly $94,050 and pay 0% on long-term capital gains and qualified dividends? That’s a huge opportunity. The 0% bracket is based on your total taxable income (including the gains themselves), so the strategy is to keep that number low by controlling other income sources.

Here’s a real scenario: Last year, a retired couple I know had $60,000 in Social Security benefits, $10,000 from a part-time job, and $20,000 in dividends from a taxable brokerage account. After the standard deduction, their taxable income was about $55,000. They sold $30,000 worth of stock that had appreciated $15,000—all long-term gains. Their total taxable income hit $70,000, still safely inside the 0% capital gains bracket. They paid zero federal tax on those gains. If they had sold the same stock in a year when they also took a large IRA distribution, the gains would have been taxed at 15%.

Practical steps for 2026: Tax-loss harvesting is your friend here. If you have losing positions in your taxable account, sell them to offset gains, then reinvest in similar (but not identical) holdings to stay in the market. Also, hold dividend-paying stocks and REITs inside tax-advantaged accounts (IRAs or 401(k)s) to avoid pushing your taxable income over the 0% threshold. And keep an eye on the net investment income tax (3.8% surtax) if your modified adjusted gross income exceeds $200,000 (single) or $250,000 (married).

5. Consider Tax Diversification and 'Bond Tent' Strategies

Tax diversification means holding assets in three buckets: taxable (brokerage accounts), tax-deferred (traditional IRAs/401(k)s), and tax-free (Roth IRAs, HSAs). The goal is to give yourself flexibility to choose which bucket to draw from each year based on your tax situation. A bond tent is a specific application of this idea: as you approach retirement, you shift a portion of your portfolio into bonds or cash equivalents (held in tax-deferred accounts) to reduce sequence-of-returns risk—the danger that a market downturn early in retirement decimates your portfolio. Because bonds generate interest income, keeping them in tax-deferred accounts shields that interest from current taxes.

I once helped a client who had 80% of his savings in a traditional IRA. When the market dropped 20% in his first year of retirement, he had to sell at a loss to cover expenses, locking in losses and triggering taxes on the withdrawals. If he had used a bond tent—say, holding three years of expenses in cash or short-term bonds inside his IRA—he could have ridden out the downturn without selling equities. The interest on those bonds stayed inside the IRA, tax-deferred, until withdrawn. That’s the beauty of tax diversification: it’s not just about minimizing current taxes; it’s about preserving your portfolio and tax flexibility for the long haul.

2026 twist: With interest rates potentially still elevated, holding bonds in tax-deferred accounts is even more tax-efficient because the interest won’t be taxed until withdrawn. Meanwhile, keep your growth-oriented assets (like stocks) in Roth accounts to maximize tax-free growth.

Frequently Asked Questions

Can I do a Roth conversion if I’m already taking Social Security?
Yes, but watch the Medicare IRMAA surcharges and Social Security taxation thresholds; converting too much could spike your income and cause up to 85% of your benefits to become taxable.

What happens to my HSA if I don’t use it for medical expenses before retirement?
After age 65, you can withdraw HSA funds for any purpose penalty-free, but only medical expenses remain tax-free; non-medical withdrawals are taxed as ordinary income.

Is the 0% capital gains tax bracket the same in 2026 as in 2025?
The income thresholds adjust annually for inflation, but the structure remains; in 2026, married filing jointly may still qualify with taxable income up to around $94,050.

How do I know if I’m withdrawing from the right account first?
Generally, start with taxable accounts (to avoid forced RMDs later), then tax-deferred (like traditional IRAs), and finally Roth (to let it grow tax-free). Adjust for your specific tax bracket.

What is the biggest mistake retirees make with taxes?
Withdrawing too much from traditional IRAs early, pushing them into a higher tax bracket and triggering Medicare surcharges, without considering Roth conversions or tax-loss harvesting.

Final takeaway: Lowering taxes in retirement isn’t about gimmicks—it’s about sequencing your income, using every tax-advantaged account fully, and keeping an eye on how your choices interact with Social Security and Medicare. Start with one strategy this year: maybe a small Roth conversion or a withdrawal-order review. Your future self—and your tax bill—will thank you.
