Understanding taxes on retirement income can save you thousands of dollars over your lifetime. According to the IRS's official retirement income guidance, most retirement income sources — including Social Security, pensions, 401(k) withdrawals, and IRA distributions — are subject to federal income tax at ordinary rates.
The problem is that many retirees assume retirement means lower taxes, only to discover that multiple income streams push them into a higher bracket than expected. This article breaks down exactly how retirement income is taxed, which states offer relief, and practical steps to minimize what you owe.
What Counts as Taxable Retirement Income?
Not all retirement income is taxed the same way. The IRS treats Social Security, traditional retirement accounts, Roth accounts, and pension payments under different rules.
- Social Security benefits become taxable only if your combined income exceeds certain thresholds. Combined income is your adjusted gross income plus nontaxable interest plus half of your Social Security benefits.
- Traditional 401(k) and IRA withdrawals are fully taxable as ordinary income because you received a tax deduction when you contributed.
- Roth IRA and Roth 401(k) withdrawals are tax-free if you meet the five-year holding rule and are at least 59½.
- Pension payments are generally taxable as ordinary income, unless you made after-tax contributions to the plan.
The Internal Revenue Service publishes detailed worksheets in Publication 915 for calculating the taxable portion of Social Security. Many retirees are surprised to learn that up to 85% of their Social Security benefits can be taxed.
How to apply this: Pull your most recent tax return and list every retirement income source you expect, then check each one against the IRS's taxable income categories.
Not every dollar you receive in later life is treated the same when it comes to taxes on retirement income.
Social Security, traditional IRAs, Roth accounts, and pensions each follow different rules for taxes on retirement income.
How Social Security Benefits Are Taxed
Social Security taxation depends entirely on your combined income level. The IRS explains that "if your combined income is between $25,000 and $34,000 for an individual, you may have to pay income tax on up to 50 percent of your benefits."
For married couples filing jointly, the threshold rises to $32,000 to $44,000. Above those upper limits, up to 85% of benefits become taxable.
Consider this scenario: A single retiree receives $24,000 in Social Security and withdraws $30,000 from a traditional IRA. Their combined income is $42,000, which exceeds the $34,000 individual threshold. That means 85% of their Social Security benefits — roughly $20,400 — becomes taxable income, on top of the $30,000 IRA withdrawal.
The tax hit can be substantial because the IRA withdrawal itself pushes Social Security into taxable territory. This stacking effect catches many retirees off guard in their first year of required minimum distributions.
How to apply this: Use the IRS Interactive Tax Assistant to check whether your Social Security benefits are taxable based on your specific income.
Your combined income level determines how much of your benefit is exposed to taxes on retirement income.
The IRS notes that single filers with combined income between $25,000 and $34,000 may owe taxes on retirement income.
State Taxes on Retirement Income: A Patchwork of Rules
Federal taxes are only half the story. State treatment of taxes on retirement income varies dramatically across the country.
Some states fully exempt Social Security benefits from state income tax, while others tax them partially or not at all. A smaller group of states — including Florida, Texas, Nevada, and Washington — have no state income tax whatsoever, which means retirement income faces no state-level tax there.
The table below breaks down common state approaches:
| State Category | What It Means | Action to Take |
|---|---|---|
| No state income tax | Florida, Texas, Nevada, Washington, Wyoming, South Dakota, Alaska, Tennessee | Check if relocating could reduce your total tax burden |
| Fully exempts Social Security | Most states (about 38) | Confirm your state's current rule annually |
| Partially taxes Social Security | A handful of states with income limits | Calculate your combined income against state thresholds |
| Taxes all retirement income | A few high-tax states | Consider Roth conversions before moving |
A common scenario involves retirees who move from a high-tax state like California to a no-tax state like Florida. The savings on taxes on retirement income alone can exceed $10,000 annually for higher-income retirees, but relocation involves more than tax math.
How to apply this: Review your state's department of revenue website for current retirement income exclusions and compare against any state you are considering for retirement.
Required Minimum Distributions and Tax Planning
Required minimum distributions (RMDs) force you to withdraw from traditional retirement accounts starting at age 73 (as of 2025). These withdrawals are fully taxable and can push you into a higher bracket.
The Secure 2.0 Act, signed into law in December 2022, gradually raised the RMD age from 72 to 73 in 2023 and to 75 by 2033. This gives retirees more time to plan conversions and manage taxable income.
One strategy many financial advisors recommend is partial Roth conversions before RMD age. By converting a portion of traditional IRA funds to a Roth each year, you pay taxes now at a potentially lower rate and reduce future RMDs.
The tradeoff is timing: conversions add taxable income in the year they occur. If you convert too much in one year, you could trigger higher Medicare premiums, which are based on modified adjusted gross income from two years prior.
How to apply this: Estimate your first-year RMD using the IRS Uniform Lifetime Table, then model whether a Roth conversion in the next two years reduces your lifetime tax bill.
Required minimum distributions force fully taxable withdrawals that complicate taxes on retirement income after age 73.
Careful planning around RMDs can keep taxes on retirement income from pushing you into a higher bracket.
Tax-Efficient Withdrawal Strategies
The order in which you withdraw from different accounts can significantly affect your total tax burden. A common framework ranks accounts by tax efficiency.
- Withdraw from taxable brokerage accounts first, using long-term capital gains rates that are often lower than ordinary income rates.
- Next, tap traditional IRAs and 401(k)s, but only up to the top of your current tax bracket.
- Leave Roth accounts for last, since qualified withdrawals are tax-free and can cover unexpected expenses without tax consequences.
This sequencing allows your Roth accounts to continue growing tax-free while you manage your ordinary income to stay within favorable brackets. It also preserves flexibility for years when you need extra cash without triggering a tax spike.
In one case, a retiree who withdrew proportionally from all accounts paid roughly $4,000 more in federal tax than one who followed the taxable-first, Roth-last sequence — despite withdrawing the same total amount.
How to apply this: Map your current account balances across taxable, traditional, and Roth categories, then test three withdrawal sequences using last year's tax software.
Withdrawing from taxable brokerage accounts first is a common way to manage taxes on retirement income.
Frequently Asked Questions About taxes on retirement income
What is the most tax-efficient way to withdraw retirement income?
The most tax-efficient approach is withdrawing from taxable accounts first, then traditional accounts, then Roth accounts. This sequencing minimizes ordinary income in any single year.
A retiree with $500,000 in taxable accounts and $500,000 in traditional IRAs might withdraw taxable funds for the first several years, keeping their taxable income low enough to avoid Social Security taxation and higher Medicare premiums.
Taxable accounts first, then traditional, then Roth is the standard sequence for minimizing taxes on retirement income.
How do required minimum distributions affect taxes on retirement income?
RMDs force taxable withdrawals from traditional accounts starting at age 73, which can push you into a higher bracket and trigger Social Security taxation. A retiree who never needed IRA withdrawals before RMD age may suddenly owe substantial tax.
The IRS calculates RMDs using your account balance divided by a life expectancy factor, so larger balances create larger mandatory withdrawals and larger tax bills.
RMDs can trigger higher brackets and Social Security taxation, raising your overall taxes on retirement income.
Are Roth IRA withdrawals ever subject to tax in retirement?
Roth IRA withdrawals are tax-free only if you meet two conditions: the account has been open at least five years, and you are at least 59½. Withdrawing earnings before meeting these conditions triggers taxes and a 10% penalty. Contributions can always be withdrawn tax-free at any age.
A retiree who converts a traditional IRA to a Roth must wait five years before withdrawing converted funds penalty-free.
Roth IRA withdrawals avoid taxes on retirement income only after five years and age 59½.
Which states are best for minimizing taxes on retirement income?
States with no income tax — Florida, Texas, Nevada, Washington, Wyoming, South Dakota, Alaska, and Tennessee — offer the lowest state tax burden on retirement income. However, some no-tax states have higher property or sales taxes that offset the savings.
A retiree moving from New York to Florida might save $8,000 in state income tax but pay $3,000 more in property tax and insurance.
States without income tax, including Florida and Texas, offer the lowest taxes on retirement income.
How can I avoid paying taxes on Social Security benefits?
Reducing your combined income below the $25,000 individual or $32,000 married threshold eliminates Social Security taxation entirely. Strategies include withdrawing from Roth accounts instead of traditional IRAs, harvesting capital losses to offset gains, or delaying Social Security while spending down taxable accounts.
A retiree with $20,000 in Social Security and $10,000 in Roth withdrawals pays no tax on benefits because Roth withdrawals do not count toward combined income.
Lowering combined income below the $25,000 or $32,000 threshold can eliminate taxes on retirement income from Social Security.
Key Takeaways
- Know your income sources: Social Security, traditional accounts, Roth accounts, and pensions all have different tax treatment under federal rules.
- Watch combined income thresholds: The $25,000 and $34,000 individual thresholds determine whether 50% or 85% of Social Security becomes taxable.
- Plan around RMDs: Withdrawals starting at age 73 can spike your taxable income; Roth conversions before that age can reduce the impact.
- Sequence withdrawals strategically: Taxable accounts first, traditional second, Roth last — this order often minimizes lifetime taxes.
Understanding taxes on retirement income is not about avoiding taxes entirely. It is about controlling when and how much you pay. Start by listing every retirement income source you expect, check your current state's rules, and model your first RMD year using tax software or a qualified advisor. The sooner you plan, the more options you have.
