How to Plan for Taxes in Retirement: 7 Strategies and Examples

Retirement does not end your tax bill. It changes where taxes come from, when they are triggered and how much control you have over them. Instead of wages and payroll withholding, retirees may rely on Social Security, pensions, traditional IRA or 401(k) withdrawals, taxable investment income, capital gains and required minimum distributions (RMDs).

A financial advisor can help you model withdrawal strategies, Roth conversions and income timing decisions so your retirement income plan is more tax-efficient.

Planning for Taxes in Retirement 

Planning for taxes in retirement means coordinating all of your income sources so you do not accidentally push yourself into a higher bracket, increase the taxable portion of Social Security or trigger Medicare surcharges. The goal is not always to pay the lowest tax in one year, but to manage taxes over many years. The following is a summary of the various sources of retirement income, as well as their general tax treatment: 

How Retirement Income Is Actually Taxed

Retirement income is not taxed all the same way. Traditional IRA and 401(k) withdrawals are generally taxed as ordinary income, while qualified Roth IRA withdrawals are tax-free. Pension income is typically taxed as ordinary income. Meanwhile, long-term capital gains from taxable brokerage accounts are taxed at capital gains rates.

Social Security follows its own rules. The IRS says up to 85% of Social Security benefits may be taxable once combined income exceeds $44,000 for married couples filing jointly, or $34,000 for many single filers. Combined income generally includes adjusted gross income, nontaxable interest and half of Social Security benefits.

This creates the so-called Social Security tax torpedo. Additional IRA withdrawals can cause more Social Security benefits to become taxable, effectively increasing the tax impact of that withdrawal.

A Sample Scenario

As an example of how this can play out, assume a married couple receives $60,000 in Social Security and takes a $40,000 traditional IRA withdrawal in 2026. Their combined income is:

$40,000 IRA withdrawal + $30,000 half of Social Security = $70,000

Because their combined income exceeds $44,000, up to 85% of benefits may be taxable. Their taxable Social Security is calculated as:

85% × ($70,000 − $44,000) = $22,100
Plus the lesser of $6,000 or 50% of benefits = $6,000
Total taxable Social Security = $28,100

Their AGI becomes:

$40,000 IRA withdrawal + $28,100 taxable Social Security = $68,100

Using the 2026 married filing jointly standard deduction of $32,200, taxable income is:

$68,100 − $32,200 = $35,900

Their federal income tax would be:

10% × $24,800 = $2,480
12% × $11,100 = $1,332
Total = $3,812

So, the $40,000 IRA withdrawal created more than $40,000 of taxable income because it also caused $28,100 of Social Security to become taxable. The 2026 standard deduction for married couples filing jointly is $32,200, and the 10% bracket applies up to $24,800 of taxable income for joint filers.

Strategies to Build Tax Diversification Before You Retire

The first step in planning for taxes in retirement is creating flexibility before withdrawals begin. If all of your savings are in tax-deferred accounts, every withdrawal may increase taxable income. A mix of taxable, tax-deferred and Roth accounts gives retirees more control.

Here are some of the ways you can go about increasing diversification.

Strategy 1: Use a Three-Bucket System

A taxable brokerage account can provide access to long-term capital gains rates. A tax-deferred account, such as a traditional IRA or 401(k), provides upfront tax benefits but creates taxable withdrawals later. Meanwhile, a Roth account can provide tax-free income if distribution rules are met. Having all three types of accoutns allows retirees to choose where income comes from each year.

Strategy 2: Consider Roth Conversions in Gap Years

The years after retirement but before RMDs begin can be a valuable period for tax planning. RMDs generally begin at age 73, though future rules will raise the age for some younger retirees.

For example, assume a married couple retires at 62 with $55,000 of taxable income before a Roth conversion. After the 2026 standard deduction of $32,200, their taxable income is $22,800. The 12% bracket for married couples filing jointly extends to $100,800, based on 2026 brackets.

That gives them:

$100,800 − $22,800 = $78,000 of 12% bracket space

If they convert $50,000 from a traditional IRA to a Roth IRA, the conversion would stay within the 12% bracket. The estimated federal tax on the conversion would be:

$50,000 × 12% = $6,000

This may reduce future RMDs and create more tax-free Roth income later.

Strategy 3: Use an HSA as a Retirement Account 

Health savings accounts (HSAs) offer a triple tax advantage: tax-deductible contributions, tax-free growth and tax-free withdrawals for qualified medical expenses. In 2026, HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, with a $1,000 catch-up contribution for eligible individuals age 55 or older.

Some retirees save receipts for qualified medical expenses and allow HSA assets to remain invested. Later, they can reimburse themselves tax-free for eligible expenses, creating another source of tax-efficient retirement cash flow.

Strategy 4: Use Dynamic Withdrawal Sequencing

Many retirees are told to withdraw from taxable accounts first, then tax-deferred accounts and then Roth accounts. That sequence can work, but it is not always tax-efficient. Instead of following a fixed order, retirees may draw from different buckets each year.

So, for instance, in a low-income year, it may make sense to take more from a traditional IRA or complete a Roth conversion. In a high-income year, Roth withdrawals or taxable account basis may help avoid higher brackets.

For example, assume a retired couple needs $90,000 of spending income. In Sequence A, they take all $90,000 from a traditional IRA. After the $32,200 standard deduction, taxable income is $57,800. Federal tax is:

10% × $24,800 = $2,480
12% × $33,000 = $3,960
Total = $6,440

In Sequence B, they take $55,000 from a traditional IRA and $35,000 from a Roth IRA. Roth withdrawals are tax-free if qualified, so taxable income before the standard deduction is $55,000. Taxable income is:

$55,000 − $32,200 = $22,800

Tax is:

10% × $22,800 = $2,280

In this year, using Roth income alongside IRA income reduces federal tax by:

$6,440 − $2,280 = $4,160

Over 10 years, if the same pattern held, the difference could be $41,600, before considering investment returns, inflation or changing tax laws.

Strategy 5: Manage RMDs Before They Begin

Once RMDs start, retirees lose some control over taxable income. Roth conversions before RMD age may reduce future balances in tax-deferred accounts. Qualified charitable distributions (QCDs) can also help charitably-inclined retirees manage taxes after age 70 ½.

A QCD allows eligible IRA owners to transfer money directly from an IRA to a qualified charity. The transfer can count toward an RMD but is excluded from AGI. For 2026, the QCD limit is $111,000 per person.

The order matters, though. If a retiree takes an RMD in cash first and then donates the money, the distribution is included in AGI. To get QCD treatment, the transfer must go directly from the IRA to the charity.

Strategy 6: Use the 0% Capital Gains Bracket

Long-term capital gains can be taxed at 0% when taxable income is below certain thresholds. For 2026, the 0% long-term capital gains rate applies to married couples filing jointly with taxable income up to $98,900.

For example, assume a married couple has $60,000 of taxable income after deductions. They could realize $38,900 ($98,900 − $60,000) of long-term capital gains at the 0% federal capital gains rate. This can allow them to reset cost basis without paying federal capital gains tax, though state taxes may still apply.

Asset location can also help. Income-producing assets, such as taxable bonds or REIT funds, may fit better in tax-deferred accounts because they often generate ordinary income. Broad stock index funds or growth-oriented assets may be more tax-efficient in taxable or Roth accounts, depending on the investor’s goals.

Strategy 7: Watch IRMAA Thresholds 

IRMAA is a Medicare surcharge based on modified adjusted gross income from two years prior. For 2026, the first IRMAA threshold begins above $109,000 for single filers and above $218,000 for married couples filing jointly. The standard 2026 Medicare Part B premium is $202.90, while the first IRMAA tier increases the Part B premium to $284.10 and adds $14.50 per month to Part D.

Assume a married couple has a MAGI of $205,000. They are below the $218,000 IRMAA threshold. If they complete a $20,000 Roth conversion, their MAGI becomes:

$205,000 + $20,000 = $225,000

That pushes them into the first IRMAA tier. The extra monthly cost is:

Part B increase: $284.10 − $202.90 = $81.20 per person
Part D surcharge: $14.50 per person
Total monthly increase: $95.70 per person

For two spouses:

$95.70 × 2 × 12 = $2,296.80 per year

If the Roth conversion is taxed at 24%, the tax is:

$20,000 × 24% = $4,800

The combined first-year tax and Medicare surcharge impact would be:

$4,800 + $2,296.80 = $7,096.80

This does not automatically mean the conversion is a mistake. But it shows why retirees should evaluate Roth conversions alongside IRMAA thresholds.
