Many people assume their tax bill will naturally decline once they stop working. While retirement may reduce employment income, it does not necessarily eliminate taxable income. Social Security benefits, pensions, traditional retirement-account withdrawals, investment gains, interest, dividends, and real-estate income can all affect the amount of tax a retiree owes. The key is understanding how these income sources interact and building a retirement strategy that considers taxes before withdrawals begin.
Article Summary
Taxes can continue throughout retirement because many common retirement-income sources may be fully or partially taxable. A thoughtful retirement tax strategy should consider:
- How withdrawals from traditional retirement accounts are taxed
- Whether a portion of Social Security benefits may be taxable
- How pension and annuity income is treated
- When required minimum distributions may begin
- How investment gains, interest, and dividends affect taxable income
- Whether Roth accounts can provide tax-free income
- How withdrawals could affect other retirement costs
- Which accounts should provide income at different stages of retirement
The goal is not necessarily to eliminate taxes. It is to understand when taxable income may be created and make informed decisions before those taxes become unavoidable.
Retirement Changes Your Income, Not the Tax System
When you retire, your paycheck may stop, but it is often replaced by several different income sources. Retirement income may include:
- Social Security benefits
- Pension payments
- Traditional IRA withdrawals
- 401(k) or 403(b) distributions
- Roth-account withdrawals
- Annuity payments
- Interest and dividends
- Capital gains
- Rental income
- Part-time employment or consulting income
Each source may receive different tax treatment. Some income may be taxable at ordinary income-tax rates, some may be taxed at capital-gains rates, and some may be tax-free when specific requirements are met. This makes retirement tax planning less about one annual tax return and more about how financial decisions may affect taxes over several years or even decades.
Traditional Retirement Accounts Create Deferred Taxes
Traditional IRAs, 401(k)s, and similar retirement accounts are often funded with pretax contributions. This can provide a tax benefit during a person’s working years, but the taxes are generally deferred rather than eliminated. Withdrawals of deductible contributions and earnings from a traditional IRA are generally taxable. Distributions from a traditional 401(k) are also generally taxable unless the money is rolled into another eligible retirement account. `That means a $1 million traditional retirement account does not necessarily provide $1 million of spendable retirement income. The amount available to support your lifestyle will depend partly on the taxes owed as funds are withdrawn.
The timing and size of those withdrawals may affect:
- Your federal income-tax bracket
- State income taxes
- The taxation of Social Security benefits
- Medicare-related costs
- The amount remaining for future years
- The taxes eventually paid by beneficiaries
Social Security May Be Taxable
Social Security benefits are not automatically tax-free.
Depending on filing status and combined income, up to 85% of a person’s Social Security benefits may be included in taxable income. The Social Security Administration currently identifies combined-income thresholds of more than $25,000 for an individual filer and more than $32,000 for a married couple filing jointly. Combined income generally considers:
- Adjusted gross income
- Tax-exempt interest
- One-half of Social Security benefits
This creates an important planning connection. A large IRA withdrawal, investment gain, pension payment, or Roth conversion could increase total income and potentially cause more Social Security benefits to become taxable. It is important to distinguish between having 85% of benefits included in taxable income and paying an 85% tax rate. Social Security benefits are not taxed at an 85% rate; instead, up to 85% of the benefit may be included in the calculation of taxable income.
Pension and Annuity Payments May Be Taxable
Pensions and annuities can provide valuable retirement income, but the payments may be fully or partially taxable. A pension or annuity payment may be fully taxable when the retiree did not contribute after-tax money to the contract. When after-tax contributions were made, part of each payment may represent a return of the retiree’s original investment and may therefore receive different tax treatment. Because pensions and annuities can vary considerably, retirees should understand:
- Whether contributions were pretax or after-tax
- Whether payments are fully or partially taxable
- Whether federal or state taxes are being withheld
- Whether survivor payments will receive the same treatment
- How the income affects other parts of the retirement plan
The IRS notes that taxable pension and annuity payments are generally subject to federal income-tax withholding.
Required Minimum Distributions Can Increase Taxable Income
Retirees cannot always leave tax-deferred money untouched indefinitely. Under current federal rules, many owners of traditional IRAs, SEP IRAs, SIMPLE IRAs, and retirement-plan accounts generally must begin taking required minimum distributions at age 73. Certain workplace-plan participants may be permitted to delay distributions until retirement, provided applicable requirements are met. Required minimum distributions can create several challenges:
- They may increase taxable income even when the money is not needed for spending.
- They may cause more Social Security benefits to become taxable.
- They may push part of a retiree’s income into a higher tax bracket.
- They may reduce control over future taxable income.
- They may affect the tax treatment of other financial decisions.
The amount required generally depends on the account balance and an IRS life-expectancy factor. As account values and distribution requirements change, the resulting taxable income may also change.
Investment Income Still Matters in Retirement
Retirees may also owe taxes on assets held outside retirement accounts. Potentially taxable investment income can include:
- Interest from savings accounts and taxable bonds
- Dividends from stocks or funds
- Capital gains from the sale of investments
- Mutual-fund capital-gain distributions
- Rental-property income
A taxable investment account can provide valuable flexibility because withdrawals of cash are not automatically taxed in the same manner as traditional IRA distributions. Instead, taxes generally depend on factors such as cost basis, realized gains, holding period, and the type of income received. This is one reason why the location of an investment can matter in addition to the investment itself. The same investment may create different tax consequences depending on whether it is held in a traditional IRA, Roth IRA, or taxable brokerage account.
Roth Accounts Can Provide Tax Flexibility
Roth accounts are funded with money that has already been taxed. When the applicable requirements are satisfied, qualified Roth IRA and designated Roth-account distributions are excluded from gross income. Tax-free Roth income can give retirees another source of funds for:
- Large purchases
- Unexpected expenses
- Years with unusually high taxable income
- Market downturns
- Legacy planning
- Managing the timing of other withdrawals
Roth accounts do not make every retirement withdrawal tax-free, but they may provide additional control over how much taxable income is created in a particular year. Conversions from traditional retirement accounts to Roth accounts generally create taxable income in the year of conversion. Therefore, conversions should be evaluated within a multiyear tax plan rather than treated as an automatic strategy.
The Order of Withdrawals Can Matter
A common retirement question is: Which account should I use first? There is no universal answer. Automatically spending taxable assets first, then tax-deferred accounts, and Roth assets last may work in some circumstances but may not produce the best result for every household. A withdrawal strategy should consider:
- Current and expected future tax brackets
- Social Security timing
- Pension start dates
- Required minimum distributions
- Available deductions
- Capital gains and cost basis
- Charitable intentions
- Healthcare and Medicare considerations
- Survivor needs
- The tax characteristics of inherited assets
For example, deliberately taking moderate traditional IRA withdrawals before required minimum distributions begin may sometimes help spread taxable income across more years. In other circumstances, preserving tax-deferred assets may be more appropriate. The objective is to coordinate withdrawals rather than viewing each account in isolation.
Retirement Tax Planning Should Include the Surviving Spouse
Taxes may change significantly after the death of one spouse. A surviving spouse may eventually move from filing a joint tax return to filing as a single taxpayer. At the same time, the survivor may continue to own many of the same taxable retirement accounts and could receive similar required distributions. Household income may decline, but the surviving spouse could still face a meaningful tax burden. Social Security income may also change because the household generally moves from two benefits to one benefit. A retirement plan should therefore evaluate not only the couple’s current tax situation but also how income and taxes may look after the first spouse dies.
Tax Planning Is an Ongoing Process
Retirement tax planning is not a one-time calculation completed on the day someone retires. Taxes should be reviewed when:
- Retirement begins
- Social Security is claimed
- A pension starts
- Required minimum distributions approach
- A Roth conversion is considered
- Investments or real estate are sold
- Tax laws change
- A spouse dies
- Significant charitable gifts are planned
- Income or expenses change substantially
Tax rules can also change over time. For example, current law provides certain eligible taxpayers age 65 or older with an enhanced federal deduction for tax years 2025 through 2028, subject to income limitations and other requirements. A strategy that works today may therefore need to be adjusted in the future.
The Bottom Line
Taxes do not necessarily disappear when employment ends. They simply begin showing up through different income sources. Traditional retirement-account withdrawals, pensions, Social Security benefits, investment income, real estate, and required distributions can all affect a retiree’s tax situation. Roth assets and taxable accounts may provide additional flexibility, but each decision should be evaluated as part of the broader retirement plan. The most useful question is not simply: “How much money have I saved?” It is: “How much of my retirement income will be available to spend after taxes?” A coordinated tax strategy can help retirees better understand that answer and make more informed decisions about income, investments, healthcare, and legacy planning.
Frequently Asked Questions
1. Are all traditional IRA withdrawals taxable?
Withdrawals of deductible contributions and tax-deferred earnings are generally taxable as ordinary income. If the account includes properly documented nondeductible contributions, part of a distribution may be treated as a tax-free return of basis.
2. Is Social Security always taxable in retirement?
No. Whether benefits are taxable depends on filing status and combined income. Some retirees owe no federal income tax on their benefits, while others may have up to 85% of their benefits included in taxable income.
3. Are Roth IRA withdrawals always tax-free?
Qualified Roth IRA distributions are tax-free. Requirements generally apply before earnings can be withdrawn tax-free, so account age, the owner’s age, and the reason for the withdrawal can matter.
4. Do retirees need taxes withheld from Social Security or pensions?
Retirees may choose to have federal taxes withheld from Social Security benefits and may also have withholding applied to pensions, annuities, and IRA distributions. The appropriate amount depends on the household’s complete tax situation. SSA currently allows voluntary Social Security withholding elections of 7%, 10%, 12%, or 22%.
5. When should retirement tax planning begin?
Ideally, planning should begin several years before retirement. This provides time to evaluate account types, Social Security timing, potential Roth conversions, capital gains, charitable strategies, and future required minimum distributions before income becomes less flexible.
