Taxes in Retirement: What Changes After You Stop Working

A regular paycheck is taxed in a way most people stop noticing after a few years. Your employer withholds federal and state taxes automatically, you file in April, and the process mostly runs itself. Retirement income doesn't work that way.

Once you stop working, where your money comes from starts to matter a lot. A withdrawal from a traditional 401(k) is taxed differently than a withdrawal from a Roth IRA. Part of your Social Security benefit may be taxable — or none of it may be, depending on your total income. And for the first time, you may have real control over how much taxable income you recognize in a given year. That control is both an opportunity and a responsibility.

This is one of the things that surprises people most in the first year or two of retirement. Not that taxes go away — but that they become something you actively manage, rather than something that just happens to you.

Your Income Sources Are Taxed Differently

In retirement, most people draw from a mix of sources. Understanding how each one is taxed is the starting point.

Traditional 401(k) and IRA withdrawals are taxed as ordinary income. Every dollar you pull out is added to your taxable income for the year, just like a paycheck used to be. You haven't paid taxes on this money yet — that's the trade-off for the upfront deduction you received when you contributed.

Roth IRA withdrawals are generally tax-free in retirement, as long as the account has been open at least five years and you're 59½ or older. You paid taxes on those contributions when you made them, so qualified withdrawals come out completely free of federal income tax.

Social Security may or may not be partially taxable, depending on your combined income. We'll cover that in the next section.

Pension income is typically taxed as ordinary income, similar to a traditional IRA.

Investment account withdrawals (from a regular brokerage account, not a retirement account) are taxed based on capital gains rates — which are often lower than ordinary income rates for most people.

None of this is designed to be confusing. It's just the result of different accounts having different tax treatment when the money went in. The IRS publishes a plain-language breakdown of retirement income atIRS.gov/retirement, which is worth bookmarking.

Social Security and the "Combined Income" Calculation

This one catches a lot of people off guard.

Up to 85% of your Social Security benefit can be subject to federal income tax. Whether that happens — and how much — depends on a figure the IRS calls "combined income" (sometimes called "provisional income"). The calculation is:

For a single person, if that combined income figure is between $25,000 and $34,000, up to 50% of your Social Security benefit may be taxable. Above $34,000, up to 85% may be taxable. For married couples filing jointly, those thresholds are $32,000 and $44,000.

One thing worth knowing: these thresholds have not been adjusted for inflation since 1984. A Social Security benefit that would have been well below the threshold decades ago may now push many people into partial taxation simply because benefits and other income have grown over time.

This doesn't mean you'll owe a large tax bill. It means that planning your withdrawals with this in mind can make a real difference. A 66-year-old with $30,000 in Social Security and $20,000 in traditional IRA withdrawals may find that a portion of their benefit is now taxable — while the same person drawing $10,000 from a Roth IRA instead might stay below the threshold entirely.

The Social Security Administration has a helpful overview of benefit taxation atSSA.gov.

Required Minimum Distributions Add Another Layer

Starting at age 73, the IRS requires you to withdraw a minimum amount each year from most traditional retirement accounts. These are called required minimum distributions, or RMDs.

RMDs are calculated based on your account balance and your age. The older you get, the larger the required percentage. A 75-year-old with $500,000 in a traditional IRA, for example, would have an RMD of roughly $21,097 for the year — money that comes out whether you need it or not and is taxed as ordinary income.

The reason this matters for tax planning: if you have a large traditional IRA or 401(k) and haven't been thinking about RMDs, the forced withdrawals starting at 73 can bump you into a higher tax bracket, increase the taxable portion of your Social Security benefit, and in some cases affect what you pay for Medicare premiums (which are income-based).

The IRS has a worksheet and RMD tables atIRS.govthat can help you estimate what your distributions will look like.

Bracket Management Becomes a Real Strategy

One thing that's different in retirement compared to your working years: you often have more flexibility over how much taxable income you recognize in a given year.

During your working years, your taxable income was largely determined by your salary. In retirement, you may be able to choose how much to withdraw from which accounts. That flexibility is the foundation of what tax professionals call "bracket management" — intentionally keeping your income in a specific tax bracket to minimize what you owe over time.

A common example: if you're in the 12% federal bracket and have room before reaching the 22% bracket, it may make sense to take a larger withdrawal from a traditional IRA in a lower-income year, converting some of it to a Roth or simply realizing income while your rate is low. This is often called a Roth conversion strategy, and it's one of the more discussed topics in retirement tax planning.

This isn't something you need to figure out on your own. A CPA or tax professional who works with people in retirement can help you model out which years to pull from which accounts. The decisions compound over time, so getting an informed perspective earlier is generally worth more than waiting.

Withholding Is No Longer Automatic

One practical detail that often surprises people in the first year of retirement: nobody is withholding taxes from your IRA withdrawals or Social Security payments unless you set that up.

You can request voluntary withholding from Social Security payments usingForm W-4V, available at IRS.gov. For IRA or 401(k) withdrawals, you can typically elect withholding when you take the distribution. Many people also set up quarterly estimated tax payments to avoid a large bill (and possible penalty) in April.

The IRS has aTax Withholding Estimator toolthat walks you through what you should be setting aside.

What Stays the Same

Not everything changes. The standard deduction still applies — and for people 65 and older, it's higher. In 2024, a single person 65 or older gets a standard deduction of $16,550 (compared to $14,600 for someone under 65). For a married couple where both spouses are 65 or older, that figure is $32,300. That extra amount can offset a meaningful portion of retirement income.

State taxes also vary significantly. Some states don't tax Social Security income at all. A few don't tax pension income or retirement account withdrawals. Where you live matters more in retirement than it did during your working years, for tax purposes.

The Bottom Line

Retirement taxes aren't harder than working-year taxes — they're just different. The biggest shift is that your income sources are more varied, some of them carry their own tax rules, and you have more ability to influence your tax bill through the choices you make. That last part is actually good news.

A tax professional who works specifically with people in or near retirement can help you model your income sources, estimate your bracket, and plan withdrawals in a way that makes sense for your situation. It's worth at least one conversation before your first full year of retirement.
