How to Minimize Taxes in Retirement: Strategies That Actually Work

Updated:
11 min read

Paul and Diana retired at 66 with $1.8 million spread across a 401(k), a Roth IRA, and a brokerage account. They felt wealthy. Then they filed their first retirement tax return.

Federal taxes: $47,000.

They'd expected maybe $20,000. After all, they were retired — no more paychecks, no more payroll taxes. How could the bill be this high?

Their accountant walked them through it. Paul had taken a large 401(k) distribution to pay off the mortgage — $180,000 in one shot. That pushed them into the 32% bracket. It also made 85% of their Social Security taxable, triggered Medicare IRMAA surcharges for the following year, and generated a state tax bill of $9,800 on top of everything.

One withdrawal decision. Nearly $50,000 in taxes.

Paul and Diana aren't unusual. Most retirees overpay on taxes — not because the tax code is unfair, but because they don't plan around it. The strategies below could have saved Paul and Diana tens of thousands of dollars. They can probably save you money too.

Strategy 1: Roth conversions during the low-income gap

The years between retirement and age 73 (when RMDs begin) often represent the lowest-income period of your adult life. Social Security may not have started yet. No paycheck. No required distributions. Your tax brackets have empty space that will never come back.

Fill that space with Roth conversions.

Here's the math for Paul and Diana. If they'd retired without taking that $180,000 distribution, their first-year income would have been about $52,000 — Social Security and some dividends. After the standard deduction, taxable income: roughly $23,000. The 12% bracket extends to about $96,950 for married filers. That leaves roughly $74,000 of bracket space at 12%.

They could convert $70,000 from the 401(k) to a Roth, pay about $8,400 in federal taxes, and move that money into a tax-free account permanently. Do that for five years: $350,000 converted at an average rate of 12%, total tax cost around $42,000. Compare that to eventually withdrawing the same $350,000 at 22% or higher once RMDs and full Social Security kick in — a tax cost of $77,000 or more.

The conversion window is finite. Once RMDs start, Social Security is in full swing, and other income fills your brackets, the opportunity narrows dramatically. Act during the gap years.

TIP

Each November, calculate your projected year-end income and identify remaining bracket space. Make your Roth conversion by mid-December to ensure it processes in the current tax year.

Strategy 2: Optimize your withdrawal order

Most retirees default to pulling from whatever account is most convenient. That's often the most expensive approach.

The conventional wisdom — spend taxable first, then tax-deferred, then Roth — is too simplistic. A dynamic withdrawal strategy adjusts annually based on your income, tax brackets, and thresholds.

For Paul and Diana, the optimized approach looks like this: use 401(k) withdrawals to fill the 12% bracket each year. Use Roth withdrawals for expenses above that — invisible to the tax code. Sell brokerage investments in years when the 0% long-term capital gains rate applies. This keeps their marginal rate at 12% or lower in most years, avoids the Social Security tax torpedo, and prevents IRMAA surcharges.

Their accountant estimated this approach saves them about $9,000 per year compared to just pulling from the 401(k) whenever they need money. Over 20 years: $180,000 in cumulative tax savings.

The key: this requires annual attention. Your optimal withdrawal mix changes as account balances shift, tax laws evolve, and income sources come and go.

Strategy 3: Harvest capital losses (and gains)

Tax-loss harvesting isn't just for working-age investors. In retirement, it's arguably more powerful because you have more control over your income.

When investments in your taxable brokerage account decline in value, sell them to realize the loss. Use that loss to offset capital gains from other sales or up to $3,000 in ordinary income per year. Then reinvest in a similar (but not "substantially identical") investment to maintain your market exposure.

But here's the retirement-specific twist: you can also harvest capital gains at the 0% rate. In 2026, married filers pay 0% on long-term capital gains if their taxable income stays below roughly $96,700. If Paul and Diana's taxable income is $50,000 in a given year, they have about $46,700 of room to realize long-term gains completely tax-free.

This is free money. Every dollar of gain they realize at 0% is a dollar that will never be taxed — even if the investment continues to appreciate. They're resetting their cost basis upward without any tax cost. In future years, when they sell those same investments, the taxable gain will be smaller because the basis is higher.

Paul kicked himself for not knowing this earlier. In their first year of retirement, they could have realized $40,000 in long-term gains from their brokerage account at 0% tax. Instead, those gains sat unrealized while Paul paid 32% on his 401(k) distribution.

Strategy 4: Bunch your deductions

The 2017 tax overhaul roughly doubled the standard deduction, which means most retirees no longer itemize. But that doesn't mean itemizing is dead — you just need to be strategic about it.

Bunching means concentrating deductible expenses into alternating years. In "bunching years," you pile up charitable contributions, medical expenses, and state/local taxes to exceed the standard deduction. In off years, you take the standard deduction.

Example: Paul and Diana give $8,000 to charity annually. Combined with $6,000 in state taxes and $4,000 in medical expenses, their total is $18,000 — below the ~$33,000 standard deduction for married filers 65+. No itemization benefit.

But what if they give two years' worth of charity in one year? They contribute $16,000 to a donor-advised fund in December, carry zero charitable giving the next year. In the bunching year: $16,000 (charity) + $6,000 (state taxes) + $4,000 (medical) = $26,000. Still below the standard deduction in this example — but if they also prepaid property taxes or had a year with high medical expenses, they could cross the threshold.

The strategy works best when your potential itemized deductions are within striking distance of the standard deduction. If you're $50,000 below, bunching won't help. If you're $5,000 below, bunching two years of charity into one can push you over.

Donor-advised funds make this easy. Contribute a lump sum, take the deduction immediately, then distribute the money to charities over several years. You front-load the tax benefit without changing your actual giving pattern.

Strategy 5: Qualified Charitable Distributions (QCDs)

If you're 70½ or older and give to charity, QCDs are one of the most tax-efficient strategies available — and one of the most underused.

A QCD allows you to transfer up to $105,000 per year (2024 limit, indexed for inflation) directly from your Traditional IRA to a qualified charity. The distribution counts toward your RMD but is excluded from taxable income entirely. It doesn't show up as income on your tax return.

This is better than taking the RMD as income and then donating the money. With a regular donation, you get a charitable deduction only if you itemize — and as we just discussed, most retirees don't itemize. With a QCD, the income exclusion works whether you itemize or not.

Diana gives $6,000 a year to her alma mater. Before learning about QCDs, she'd take money from the 401(k), pay tax on it, then write a check to the university. Now she directs $6,000 of her RMD straight to the school. That $6,000 never appears as income, saving her roughly $1,400 in federal taxes annually. She's giving the same amount to the same charity — the only difference is the plumbing.

IMPORTANT

The QCD must go directly from the IRA custodian to the charity. If the money touches your bank account first, it doesn't qualify. Set up the transfer with your IRA provider before the distribution.

Strategy 6: Manage Social Security taxation thresholds

Up to 85% of Social Security benefits can be taxable, but the thresholds that determine how much is taxed are surprisingly low — and they haven't been inflation-adjusted since 1993.

For married couples filing jointly, the key numbers: combined income below $32,000 means Social Security is tax-free. Between $32,000 and $44,000, up to 50% is taxable. Above $44,000, up to 85% is taxable.

Combined income = AGI + nontaxable interest + half of Social Security benefits.

Most retirees with any meaningful retirement savings blow past these thresholds without trying. But managing how far past makes a difference. The tax torpedo zone between $32,000 and $44,000 of combined income creates effective marginal rates of 22.2% to 40.7% — far higher than the nominal bracket — because each dollar of additional income makes more Social Security taxable.

Paul and Diana's approach: in years when they need extra income beyond their bracket-filling 401(k) withdrawal, they pull from the Roth. Roth withdrawals don't count toward combined income, so they don't increase Social Security taxation. It's as if the money doesn't exist in the eyes of the Social Security tax formula.

This one adjustment — using Roth instead of 401(k) for discretionary spending above the bracket threshold — saves them an estimated $2,000–$3,000 per year in Social Security-related taxes.

Strategy 7: Consider state taxes — including relocation

Federal taxes get most of the attention, but state taxes can add 3% to 13% on top. And unlike federal rules, state tax treatment of retirement income varies wildly.

Seven states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming (New Hampshire taxes only interest and dividends). Several more exempt retirement income partially or fully — Illinois, Mississippi, and Pennsylvania exempt most retirement distributions.

Paul and Diana live in New Jersey, which taxes retirement income at rates up to 10.75%. On their $47,000 federal tax bill, they paid an additional $9,800 in state taxes. If they moved to Florida — where Diana's sister lives and they've considered relocating anyway — that $9,800 would disappear entirely.

Over a 25-year retirement, that's $245,000 in state tax savings. Even accounting for differences in cost of living, property taxes, and moving costs, the math often favors relocation for retirees in high-tax states.

But relocation isn't for everyone, and we won't pretend it is. Uprooting from a community you've lived in for decades — leaving friends, doctors, favorite restaurants, and familiar streets — has a real cost that doesn't show up on a tax return. Some retirees move and love it. Others move and regret it. The financial case is often clear; the personal case is rarely so simple.

If you're not willing to relocate, focus on the other six strategies. They work regardless of your ZIP code.

The honest truth about tax planning

Not every strategy works for everyone. QCDs only help if you're 70½+ and give to charity. Roth conversions only save money if your future tax rate exceeds your current rate. Tax-loss harvesting requires unrealized losses in a taxable account. Relocation requires willingness to move.

And tax laws change. The current bracket structure, set by the 2017 Tax Cuts and Jobs Act, is scheduled to sunset after 2025 — though congressional action may extend it. Strategies optimized for today's brackets may need adjustment if rates increase.

The common thread across all seven strategies is this: pay attention. Most retirees who overpay taxes do so not because the strategies are too complex, but because they never look at the full picture. They make withdrawal decisions in isolation, miss the interaction effects between Social Security and IRA distributions, don't know about QCDs, and file their taxes reactively instead of planning proactively.

Paul and Diana's $47,000 tax year was a wake-up call. The following year, working with their accountant on a comprehensive plan, their federal tax bill dropped to $11,200. Same spending. Same lifestyle. Different strategy.

That $36,000 difference paid for a lot of dinners out — and bought them something money can't usually buy: the feeling that they weren't leaving a single dollar on the table.

Frequently Asked Questions

Roth conversions during the gap years (retirement to age 73) when income is lowest. Fill the 12% bracket with conversions — pay 12% now to avoid 22%+ later. Optimize withdrawal order: use 401(k) to fill low brackets, Roth for overflow.

The years between retirement and RMDs (age 73) — when Social Security may not have started and you have empty bracket space. Each November, calculate year-end income and remaining bracket space. Convert by mid-December.

Use 401(k) withdrawals to fill the 12% bracket. Use Roth for expenses above that — Roth withdrawals are invisible to the tax code. Sell brokerage investments when the 0% capital gains rate applies. This avoids the Social Security tax torpedo and IRMAA.

A range where each additional dollar of 401(k) income effectively creates $1.50 or $1.85 of taxable income because it pushes more Social Security into taxation. Managing withdrawal sources to stay below or above this zone saves thousands.

Manage your MAGI — Medicare uses income from two years prior. Roth conversions before age 63 do not affect age-65 premiums. Use Roth withdrawals instead of Traditional when possible. Stay under $106,000 (single) or $212,000 (joint) if you can.
