2025 Federal Tax Guide for Retirees

1. Understanding Retirement Income Types

Most retirees have more than one source of income, and each is taxed differently. Common retirement income sources include:

• Social Security benefits
• Pension income
• Traditional IRA and 401(k) withdrawals
• Roth IRA withdrawals
• Investment income (interest, dividends, capital gains)
• Part‑time work or consulting income

Each category affects your tax bracket and whether your Social Security benefits become taxable.

2. How Social Security Is Taxed in 2025

Social Security benefits may be taxable depending on your combined income, which is generally:

Adjusted gross income + nontaxable interest + ½ of your Social Security benefits

For 2025, Social Security becomes taxable when combined income exceeds:

• Single: $25,000
• Married Filing Jointly: $32,000

Up to 85% of your benefits may be taxable, but never 100%.

Example

A married couple with $40,000 in Social Security and $30,000 in IRA withdrawals will likely have a portion of their benefits taxed—potentially up to 85%—depending on their other income.

3. Required Minimum Distributions (RMDs)

If you are 73 or older, you must take required minimum distributions from most tax‑deferred retirement accounts, including:

• Traditional IRAs
• 401(k)s and 403(b)s
• Most employer‑sponsored retirement plans

RMDs are generally fully taxable as ordinary income and can push you into a higher tax bracket or increase the taxable portion of your Social Security benefits.

4. Roth Withdrawals and Tax Planning

Roth IRA withdrawals (when qualified) are:

• Generally tax‑free
• Do not increase your taxable Social Security
• Not subject to RMDs during your lifetime

This makes Roth accounts powerful tools for managing your tax bracket and controlling how much of your Social Security becomes taxable.

5. Capital Gains for Retirees

Long‑term capital gains may be taxed at 0%, 15%, or 20%, depending on your taxable income. Retirees with modest income sometimes qualify for the 0% capital gains rate, which can be a valuable planning opportunity.

Coordinating IRA withdrawals, Social Security timing, and investment sales can help you stay in a lower bracket and reduce overall taxes.

6. Common Tax Mistakes Retirees Make

• Taking large IRA withdrawals early in retirement without considering tax brackets
• Triggering unnecessary taxation of Social Security benefits
• Missing RMD deadlines and facing penalties
• Not coordinating withdrawals across taxable, tax‑deferred, and Roth accounts
• Filing Married Filing Separately without understanding credit limitations

7. How to Plan Your Retirement Taxes

A thoughtful withdrawal strategy can reduce lifetime taxes and help your savings last longer. Modeling different scenarios is one of the most effective ways to see the impact of:

• Different IRA withdrawal amounts
• Roth conversions
• Delaying or starting Social Security
• Harvesting capital gains in low‑income years

You can use the TaxWise Assistant tools to explore these scenarios before making decisions.

Conclusion

Retirement taxes don't have to be overwhelming. By understanding how Social Security, RMDs, Roth accounts, and investment income interact, you can make more informed decisions and avoid unpleasant surprises at tax time.

A bit of planning now can translate into meaningful tax savings over the rest of your retirement.
