How Retirement Income Is Taxed in the U.S. in 2026

Your retirement cash flow and your taxable income are different numbers. A pension payment, a sale of investments and a qualified Roth withdrawal may all pay household bills, but they enter the federal tax calculation differently. Start by identifying the source of each dollar.

Pensions and annuities

Pension payments are generally fully taxable when you have no after-tax investment in the contract. When you contributed after-tax money, part of a payment may be a tax-free recovery of that cost. The calculation depends on the arrangement; do not assume every pension or annuity payment is entirely taxable or entirely tax-free. Compare the gross and taxable amounts on Form 1099-R with the IRS pension and annuity rules.

Traditional and Roth IRA withdrawals

Traditional IRA distributions are generally ordinary income, except for the portion attributable to nondeductible contributions under the applicable basis rules. Taking money from one IRA does not necessarily isolate its after-tax dollars from your other IRAs.

Qualified Roth IRA distributions are tax-free. Nonqualified distributions require closer attention to ordering and timing rules. A conversion from a traditional IRA to a Roth generally produces taxable income to the extent converted funds have not already been taxed. Review IRS Topic 451 before treating a withdrawal or conversion as tax-free.

Social Security has a separate calculation

Depending on filing status and other income, up to 85% of Social Security benefits can be included in taxable income. That is the taxable share, not an 85% tax rate. The initial calculation considers other income, tax-exempt interest and half the benefits. Use the IRS Social Security guidance and our worked Social Security taxation example for the next step.

Investment sales are different from withdrawals

In a taxable brokerage account, the sale proceeds are not automatically all income. The gain or loss generally compares proceeds with adjusted basis. Short-term gains generally receive ordinary income treatment; long-term gains can qualify for different federal rates. The applicable rate depends on total taxable income and the asset. See IRS capital gains guidance.

For example, selling an investment for $10,000 with an $8,000 adjusted basis creates a $2,000 gain before any relevant adjustments. That is different from withdrawing $10,000 of fully taxable traditional IRA money. Record both the cash received and the taxable amount in your budget.

The additional deduction for seniors

For 2025 through 2028, eligible people age 65 or older may claim an additional deduction of up to $6,000 each, or $12,000 for a married couple when both qualify. It begins phasing out above modified adjusted gross income of $75,000, or $150,000 for joint filers. This is separate from the existing age-based additional standard deduction. See the IRS senior deduction explanation.

A deduction reduces taxable income; it does not reimburse that amount or make every retirement payment tax-free. Review eligibility and the tax-year instructions before estimating the saving.

Build an annual tax worksheet

List expected wages, pension payments, account distributions, benefits, interest, dividends and investment sales. Separate gross cash from estimated taxable amounts. Check distribution requirements and deadlines with each retirement-account provider, including any inherited accounts.

Next, apply deductions and credits and compare projected tax with withholding already scheduled. Federal estimated payments may be necessary when withholding is insufficient. The IRS underpayment guidance explains the payment requirements and exceptions.

Run this review before a large withdrawal or conversion, then update it when circumstances change. Include your state's rules separately. A federal tax estimate alone does not establish the total cost of the decision, especially when health insurance assistance or income-based Medicare premiums may also be affected.
