Will Your Social Security Be Taxed in 2026? What to Know

The Question I Hear More Than Any Other Right Now

In my 18 years as a Certified Financial Planner, the single question dominating every client meeting this spring is deceptively simple: “Will my Social Security be taxed in 2026?” The short answer is that it depends on your total income—but the full answer involves outdated thresholds, potential legislative changes, and planning moves that could save you thousands of dollars a year.

Here’s what frustrates me as a practitioner: the rules governing Social Security taxation haven’t been updated since 1993. That’s more than three decades of inflation silently dragging middle-income retirees into a tax they were never intended to pay. According to the Social Security Administration, roughly 56% of beneficiary households now owe federal income tax on at least a portion of their benefits—up from fewer than 10% when the tax was first introduced in 1984.

Let me walk you through exactly how this tax works in 2026, who owes it, and—most importantly—what you can do about it before the year is over.

How Social Security Benefits Are Taxed: The Rules for 2026

The federal taxation of Social Security benefits hinges on a single number: your “combined income,” also called provisional income. The IRS calculates it using this formula:

Combined Income = Adjusted Gross Income (AGI) + Nontaxable Interest + 50% of Social Security Benefits

Once you know your combined income, two threshold tiers determine how much of your Social Security is taxable. These thresholds have remained frozen since 1993—no inflation adjustments, no cost-of-living updates, nothing.

Filing Status	Combined Income Threshold	% of Benefits Potentially Taxable
Single / Head of Household	Below $25,000	0% — no tax on benefits
Single / Head of Household	$25,000 – $34,000	Up to 50%
Single / Head of Household	Above $34,000	Up to 85%
Married Filing Jointly	Below $32,000	0% — no tax on benefits
Married Filing Jointly	$32,000 – $44,000	Up to 50%
Married Filing Jointly	Above $44,000	Up to 85%

Let me put real numbers to this. If you’re a single retiree collecting the average Social Security benefit of $1,976 per month (about $23,712 annually as of early 2026) and you have $15,000 in pension income plus $3,000 in interest, your combined income is roughly $29,856. That puts you squarely in the 50% taxable tier—meaning up to $11,856 of your Social Security could be added to your taxable income.

For a married couple both collecting benefits totaling $40,000 a year with a modest $20,000 in IRA withdrawals, combined income easily exceeds $44,000. Up to 85% of their benefits—$34,000—becomes taxable. That’s a real tax bill many couples don’t see coming.

Why 2026 Is a Particularly Important Year

Several converging factors make Social Security taxation especially relevant in 2026. What I see most often is clients who planned their retirement around 2024 or 2025 tax rules without accounting for shifts arriving this year.

The 2025 COLA and Its Ripple Effect

The 2.5% cost-of-living adjustment (COLA) that took effect in January 2025 increased the average monthly benefit. While that extra income helps offset inflation, it also pushes more retirees above the frozen tax thresholds. The 2026 COLA, projected by some analysts to land between 2.0% and 2.8%, will compound this effect further.

Tax Cuts and Jobs Act Provisions Sunsetting

Many provisions of the 2017 Tax Cuts and Jobs Act (TCJA) are scheduled to expire after December 31, 2025, unless Congress acts. If they do expire, individual income tax rates will revert to higher pre-2018 levels. For a retiree in the current 12% bracket, that could mean jumping back to 15%. Combined with taxable Social Security, the effective tax increase could be substantial. For a deeper dive into these shifts, see our overview of Social Security tax changes in 2026 that seniors must know.

Legislative Proposals: Hope, but Not a Plan

The Social Security Tax Fairness Act and similar proposals have gained bipartisan attention, with some lawmakers demanding the elimination or reduction of federal taxes on benefits. Representative Davids and others have publicly called for transparency and relief. However, I always tell my clients: plan based on current law, then adjust if legislation passes. Hoping a bill will save you is not a retirement strategy.

Do You Even Need to File a Tax Return in 2026?

This is a critical question many seniors overlook. If Social Security is your only source of income, you very likely do not need to file a federal return. The IRS generally does not require a return if your gross income is below the standard filing threshold, which for 2025 (the return you’d file in early 2026) is $16,550 for a single filer age 65+ and $32,300 for married filing jointly with both spouses 65+.

But here’s the catch: Social Security benefits only count toward gross income to the extent they’re taxable. So if your combined income stays below $25,000 (single) or $32,000 (married), none of your Social Security is taxable, and you likely don’t need to file.

However, you may want to file even if you don’t have to—for example, to claim refundable credits or to recover withheld taxes. I’ve put together a detailed breakdown at Seniors on Social Security: Must You File Taxes in 2026? that walks through this decision step by step.

Six Strategies to Reduce or Eliminate Taxes on Your Social Security

Here’s where planning makes a real, measurable difference. These aren’t theoretical ideas—they’re strategies I implement with clients regularly, and the results can be dramatic.

1. Manage Your IRA and 401(k) Withdrawals Strategically. Every dollar you pull from a traditional IRA or 401(k) increases your AGI—and therefore your combined income. If you can keep withdrawals to the minimum required (your RMD), or spread larger withdrawals across multiple tax years, you may stay below a taxable threshold. For 2026, Required Minimum Distributions start at age 73 under the SECURE 2.0 Act.
2. Execute Roth Conversions in Lower-Income Years. Converting traditional IRA funds to a Roth IRA triggers taxable income in the year of conversion—but future Roth withdrawals are tax-free and do not count toward combined income. If you have a gap year between retiring and claiming Social Security, or a year with unusually low income, that’s the ideal window. I often tell clients this is the single most powerful move retirees can make, but timing is everything.
3. Use Qualified Charitable Distributions (QCDs). If you’re 70½ or older, you can direct up to $105,000 (2024 limit, indexed for inflation) from your traditional IRA directly to a qualified charity. The distribution satisfies your RMD but does not count as taxable income—keeping your combined income lower and potentially keeping your Social Security tax-free. This is my favorite strategy for charitably inclined retirees because the math is so clean.
4. Consider Tax-Exempt Investments Carefully. Municipal bond interest is exempt from federal income tax, but here’s the trap: it is included in the combined income calculation for Social Security taxation. So switching to munis doesn’t necessarily help. On the other hand, Roth IRA withdrawals and return-of-principal from non-qualified accounts are excluded from both AGI and combined income. Work with a tax-aware advisor to choose the right mix.
5. Time Your Income Across Calendar Years. If you’re selling a home, cashing in savings bonds, or taking a pension lump sum, the year you do it matters enormously. Bunching large income events into one year—and accepting a higher tax that year—can keep adjacent years below the thresholds. I’ve seen couples save $4,000 to $8,000 over a three-year period simply by shifting the timing of a single transaction.
6. Coordinate With Medicare Premium Surcharges. Your modified adjusted gross income (MAGI) also determines whether you pay Income-Related Monthly Adjustment Amounts (IRMAA) on Medicare Parts B and D. The same strategies that reduce Social Security taxation often reduce IRMAA surcharges, creating a double benefit. With Medicare costs climbing in 2026, this coordination is more valuable than ever—see our analysis of higher Medicare costs in 2026 for specifics.

A Real-World Example: How $6,200 in Taxes Disappeared

Let me share a simplified version of a client scenario I worked through last year. Tom and Linda, both 72, had combined Social Security benefits of $46,000. Tom had a traditional IRA requiring an RMD of $18,000, and they earned $4,500 in bank interest. Their combined income was approximately $45,500—putting 85% of their Social Security (about $39,100) on the taxable line.

We made two changes. First, Tom directed $10,000 of his RMD as a QCD to his church. Second, we had started Roth conversions two years earlier, so a portion of what would have been traditional IRA withdrawals were now coming from his Roth—tax-free and invisible to the combined income formula.

The result: their combined income dropped to roughly $31,800—just below the $32,000 married threshold. Zero Social Security benefits were taxable. The federal tax savings exceeded $6,200 compared to their pre-planning scenario. That’s real money that stayed in their retirement accounts.

What About State Taxes on Social Security?

Federal taxation is only half the picture. As of 2026, the majority of states do not tax Social Security benefits. However, a handful still do—including Colorado, Connecticut, Minnesota, Montana, New Mexico, Rhode Island, Utah, Vermont, and West Virginia—though many of these offer exemptions based on age or income.

If you’re considering relocating in retirement, tax treatment of Social Security is one factor to weigh alongside cost of living, healthcare access, and quality of life. According to Investopedia, the total state tax burden on retirees varies dramatically, and the difference can amount to thousands of dollars annually.

Financial stress also takes a measurable toll on well-being. Research consistently shows that physical health is key to seniors’ mental health, and unnecessary tax bills directly undermine financial security, which in turn affects both.

The Inflation Factor: Why This Problem Keeps Getting Worse

William Bengen, the financial planner who originated the famous 4% withdrawal rule, recently called inflation retirees’ “greatest enemy.” He’s right—and the Social Security tax threshold freeze is a perfect illustration of why.

If the $25,000 single threshold had been indexed to inflation since 1993, it would be approximately $53,000 today. The $32,000 married threshold would be around $68,000. Instead, they remain stuck at levels set when the average Social Security benefit was under $700 a month. The average benefit in early 2026 is nearly $2,000.

This bracket creep means more middle-income retirees pay taxes on their Social Security every single year—regardless of whether their real purchasing power has increased. Surveys show that older adults are depleting retirement savings earlier than expected, and unexpected tax bills on Social Security are a contributing factor.

Your Action Plan for 2026

Don’t wait until tax season to figure this out. The most effective strategies require action during the tax year, not after it ends. Here’s what I recommend:

• Run a combined income projection now. Use last year’s return as a baseline, then adjust for any changes in Social Security, pensions, RMDs, and investment income.
• Identify which threshold tier you’re in—or close to. If you’re within $5,000 of a threshold boundary, even small adjustments can shift your tax outcome significantly.
• Talk to a tax-savvy financial planner or CPA before December 31. Roth conversions, QCDs, and income timing must be completed within the calendar year to count.
• Review your Medicare IRMAA exposure at the same time. The income lookback for 2026 IRMAA is typically your 2024 MAGI—but planning for 2027 IRMAA starts with what you do in 2025 and 2026.
• Keep records of all QCDs and Roth conversions. Proper documentation prevents IRS headaches later.

Whether your Social Security will be taxed in 2026 isn’t entirely out of your control. With informed planning and timely action, many retirees can meaningfully reduce—or completely eliminate—the federal tax on their benefits. The frozen thresholds make this harder every year, which is precisely why proactive strategy matters more than ever.
