How Much of Your Social Security Is Taxed?
The Big Beautiful Bill adds a $6,000 below-the-line deduction for taxpayers age 65+ with AGI under $75,000 (single) or $150,000 (joint) for tax years 2025–2028. This deduction is separate from and stacks on top of the standard deduction — any taxpayer 65+ under the income threshold qualifies, whether or not they receive Social Security. Married filing separately filers are excluded. But the thresholds that determine how much of your Social Security is taxable haven’t been updated since 1993 — they aren’t indexed for inflation, meaning more retirees pay tax on their benefits every year.

Many retirees are surprised to learn that Social Security can be taxable even when they do not consider themselves high income. That surprise comes from frozen thresholds that have not kept pace with inflation, not from a sudden jump in benefits.
This is a classic policy-risk issue. The rules look stable, but the household effect keeps widening because wages, retirement withdrawals, and other income rise over time while the taxation thresholds stay stuck in place.
Up to 85% of your Social Security benefits may be subject to federal income tax. The Big Beautiful Bill adds a $6,000 below-the-line deduction for taxpayers age 65+ earning under $75,000 (single) or $150,000 (joint), effective for tax years 2025–2028 — but it won’t help everyone. Enter your details to see exactly how much of your benefits are taxed.

Frequently Asked Questions
- How much of my Social Security is taxable?
- It depends on your "combined income" — your AGI plus nontaxable interest plus half of your Social Security benefits. Below $25,000 (single) or $32,000 (joint), none is taxable. Between $25,000–$34,000 (single) or $32,000–$44,000 (joint), up to 50% is taxable. Above those thresholds, up to 85% is taxable. Note: 85% is the maximum — your benefits are never 100% taxable.
- Why are Social Security tax thresholds so low?
- The thresholds were set at $25,000/$32,000 in 1983 and $34,000/$44,000 in 1993. Unlike tax brackets, they are NOT indexed for inflation. If they had been inflation-adjusted, the 50% threshold would be roughly $52,000 (single) today. This "bracket creep" means more retirees pay tax on their benefits every year.
- What is the Big Beautiful Bill senior deduction?
- The Big Beautiful Bill adds a $6,000 additional standard deduction for Social Security recipients age 65+ for tax years 2026–2028. It applies per qualifying individual (so a married couple where both are 65+ could get $12,000). AGI must be under $75,000 (single) or $150,000 (joint). It reduces taxable income, not the amount of Social Security that is counted as taxable.
- How much will the BBB senior deduction save me?
- The savings depend on your marginal tax rate. At the 10% bracket, the $6,000 deduction saves $600. At 12%, it saves $720. At 22%, it saves $1,320. Married couples 65+ where both qualify get double the deduction. The deduction expires after 2028.
- What counts as "combined income" for Social Security taxes?
- Combined income = your adjusted gross income (AGI) + nontaxable interest (e.g., municipal bond interest) + half of your Social Security benefits. This includes wages, pensions, 401(k)/IRA withdrawals, investment income, and rental income. It does NOT include Roth IRA withdrawals.
- Do all states tax Social Security benefits?
- No. Most states exempt Social Security from state income tax. As of 2026, 13 states tax Social Security to varying degrees: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Rhode Island, Utah, Vermont, and West Virginia. Most of these have their own income-based exemptions.
- Can I reduce the tax on my Social Security benefits?
- Strategies include: (1) managing retirement withdrawals to stay below the 85% threshold, (2) using Roth conversions before claiming Social Security to reduce future RMDs, (3) timing investment gains and losses, (4) considering municipal bonds for interest income, and (5) choosing a state that doesn't tax Social Security. The goal is to keep "combined income" as low as possible.
- Is there a "tax torpedo" effect with Social Security?
- Yes. The "tax torpedo" describes the zone where each additional $1 of income can make $0.50–$0.85 of Social Security taxable, effectively creating a marginal rate 50–85% higher than your stated bracket. A retiree in the 22% bracket can face an effective marginal rate of 40.7% in the torpedo zone.
- Are Social Security disability benefits taxed the same way?
- Yes. Social Security Disability Insurance (SSDI) benefits follow the exact same taxation rules as retirement benefits — the same combined income thresholds and the same 50%/85% taxability rules apply.
- How accurate is this calculator?
- This calculator uses the IRS Publication 915 worksheet methodology and 2026 tax brackets. It provides a close estimate of federal tax on your Social Security benefits. Actual amounts depend on your complete tax situation including deductions, credits, and state taxes. Consult a tax professional for personalized advice.

Up to 85% of your Social Security benefits can become taxable at the federal level depending on your combined income. The important catch is that the income thresholds that trigger taxation are not indexed to inflation, so more retirees get pulled in over time even without dramatic policy headlines.
How Social Security Benefits Are Taxed
The IRS uses “combined income” to determine how much of your Social Security is taxable. Combined income = your adjusted gross income + nontaxable interest + half of your Social Security benefits. Based on this number:
- Below $25,000 (single) / $32,000 (joint): None of your benefits are taxable
- $25,000–$34,000 (single) / $32,000–$44,000 (joint): Up to 50% of benefits are taxable
- Above $34,000 (single) / $44,000 (joint): Up to 85% of benefits are taxable
The Inflation Problem No One Talks About
These thresholds were set in 1983 and 1993 and have never been adjusted for inflation. In 1984, only about 8% of Social Security recipients paid tax on their benefits. Today, roughly 56% do — and that percentage grows every year as wages and retirement income rise while the thresholds stay frozen.
If these thresholds had been indexed to inflation since 1993, the 50% bracket would start at approximately $52,000 (single) instead of $25,000. This “stealth tax increase” is one of the most significant inflation-driven tax changes affecting retirees.
Why The Freeze Matters For Planning
The freeze means Social Security taxation is no longer just a question for obviously affluent retirees. IRA withdrawals, pension income, part-time work, interest income, or even a modest Roth conversion can change how much of your benefit is taxable.
That makes the tax treatment of Social Security part of a broader retirement-income strategy, not a line item you can safely ignore.
What the Big Beautiful Bill Changes
The BBB does not fix the frozen thresholds. Instead, it adds a temporary $6,000 below-the-line deduction for any taxpayer age 65+ with income under the phase-out threshold, available for tax years 2025–2028. This means you can claim it on the 2025 return you are filing right now. Key details:
- It is a below-the-line deduction that stacks on top of the standard deduction and the existing age-65+ additional standard deduction — it is not a standard deduction
- Any taxpayer 65+ qualifies if income is under the threshold, whether or not they receive Social Security benefits
- Married filing separately filers are excluded
- AGI must be under $75,000 (single) or $150,000 (joint), with a gradual phase-out above those levels
- It reduces overall taxable income, not the amount of Social Security counted as taxable — so the dollar benefit depends on your marginal tax rate
- At the 12% bracket, the deduction saves $720; at 22%, it saves $1,320 — higher-bracket retirees benefit more in dollar terms
- It expires after 2028 with no automatic extension
Why a Deduction Instead of Eliminating Social Security Taxes?
During the 2024 campaign, Trump promised “no tax on Social Security.” The OBBBA did not deliver that literally. The reason is procedural: the bill was passed through budget reconciliation, which prohibits provisions that directly change Social Security. The Byrd Rule would have blocked any provision altering the IRC § 86 thresholds that determine how much Social Security is taxable, because those thresholds are part of the Social Security program’s statutory framework.
The workaround was a general senior deduction that reduces taxable income without modifying Social Security rules. This structure complies with reconciliation requirements but means the frozen thresholds remain in place, the deduction is temporary (2025–2028), and it only partially offsets the tax on benefits for eligible filers.
States That Tax Social Security
Most states exempt Social Security from state income tax, but 12 states tax it to varying degrees as of 2026: Colorado, Connecticut, Kansas, Minnesota, Missouri, Montana, Nebraska, New Mexico, North Dakota, Rhode Island, Utah, and Vermont. West Virginia fully exempted Social Security benefits starting in 2024. Several of the remaining states have their own income-based exemptions. This calculator shows federal tax only.
