Your State's Social Security Tax Rules: What Retirees Need to Know in 2025

When retirement arrives, every dollar counts. Yet many Americans don’t realize that their Social Security benefits may be subject to state income tax—a fact that can significantly impact their financial security. Understanding how many states tax Social Security and where you stand is crucial for proper retirement planning.

The Shrinking List of States That Tax Social Security

Here’s the good news: only nine states currently tax Social Security benefits, and this number keeps declining. As of 2025, the states maintaining Social Security income taxes are Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, Vermont, and West Virginia. However, West Virginia is phasing out this tax entirely, with elimination scheduled for 2026.

The trend is moving in retirees’ favor. Missouri, Nebraska, and Kansas have all recently eliminated Social Security taxation, removing themselves from the taxing states list. This represents a significant shift toward protecting retirement income nationwide.

41 States Offer Full Social Security Tax Relief

The overwhelming majority of states—41 plus Washington, D.C.—provide complete exemption from state income tax on Social Security benefits. This includes major retirement destinations like Florida, Texas, and Nevada, as well as traditional northeastern states such as New York and Massachusetts.

The full roster of tax-exempt states encompasses Alabama, Alaska, Arizona, Arkansas, California, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Missouri, Nebraska, Nevada, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Texas, Virginia, Washington, and Wisconsin.

Why This Matters: Federal Taxation Complications

Understanding your state’s rules becomes even more important when combined with federal tax exposure. Up to 85% of your Social Security benefits may be subject to federal income taxation, depending on your overall income level. In states that don’t tax Social Security, you at least eliminate the state portion of this burden. According to AARP data, 40% of Americans over 65 rely on Social Security for at least half their retirement income—making tax efficiency a serious consideration.

Real Savings: What Do These Tax Exemptions Mean?

The financial impact is substantial. Financial expert Jeff Rose notes that Missouri retirees collectively save approximately $309 million annually by avoiding state Social Security taxes. Nebraska retirees preserve about $17 million yearly through the same protection. These aren’t trivial amounts—they represent real money staying in retirees’ bank accounts rather than flowing to state governments.

To calculate your potential savings, determine your state’s effective tax rate on all income sources, then apply it to your total Social Security benefits. If your state’s effective rate is 5% and you receive $30,000 annually in benefits, you’re saving $1,500 yearly—$18,000 over a decade.

Important Exceptions: Not All Residents Pay Full Tax

Some states that tax Social Security offer partial relief through exemptions. Colorado provides full exemption for residents 65 and older since 2022. In 2025, Colorado expanded this to include those ages 55–64 earning $75,000 or less (individuals) or $95,000 or less (joint filers). This demonstrates that state rules are nuanced and frequently change, requiring careful review of your specific circumstances.

According to financial advisor Brian Kuhn, CFP at Wealth Enhancement Group: “Each state makes its own rules, which sometimes change. And each state has tax provisions that could provide deductions for individuals below certain thresholds or ages, making each state unique.” This underscores why consulting your state’s current tax code matters, especially if you’re in one of the nine states that do tax these benefits.

Planning Your Retirement Tax Strategy

The key takeaway: how many states tax Social Security continues to shrink. If you’re retired or approaching retirement, knowing whether your state offers relief can help you optimize your overall tax position. Those fortunate enough to live in a state without Social Security taxation gain a meaningful advantage in preserving retirement income.

For those in the nine taxing states, understanding available exemptions—based on age, income thresholds, or recent legislative changes—remains essential. Retirement income is earned income; it deserves the same tax-minimization strategy you’d apply to any other financial decision.
