Federal vs State Taxes on Social Security – Social Security benefits provide essential retirement income for millions of Americans, but understanding how they’re taxed at the federal and state levels is crucial for accurate planning. Many retirees wonder: “Is Social Security taxable?” The answer depends on your total income and where you live. While federal rules remain consistent, state rules vary widely. This guide breaks down the latest 2026 rules using official IRS sources and current state tax data to help USA residents minimize surprises during tax season.
How Federal Taxes on Social Security Benefits Work?
The federal government may tax up to 85% of your Social Security benefits, but only if your income exceeds specific thresholds. These thresholds—unchanged for decades—use “combined income” (also called provisional income), calculated as:
- Your adjusted gross income (AGI)
-
- Nontaxable interest (e.g., municipal bonds)
-
- One-half of your Social Security benefits
Federal thresholds (2025 and 2026 tax years):
- Single, Head of Household, or Qualifying Surviving Spouse:
- Combined income under $25,000 → 0% taxable
- $25,000–$34,000 → Up to 50% taxable
- Over $34,000 → Up to 85% taxable
- Married Filing Jointly:
- Combined income under $32,000 → 0% taxable
- $32,000–$44,000 → Up to 50% taxable
- Over $44,000 → Up to 85% taxable
- Married Filing Separately: Usually $0 threshold (unless you lived apart all year).
The IRS provides Worksheet 1 in Publication 915 to calculate the exact taxable amount. You report benefits on Form 1040 (line 6b). Up to 85% of benefits can be included in taxable income, but the exact percentage depends on your worksheet results.
Important note on 2025/2026 changes: Despite rumors from the 2025 Tax Act, federal taxation rules for Social Security benefits have not changed. Benefits remain taxable based on the longstanding thresholds. A new senior deduction (up to $6,000 per qualifying person age 65+ with AGI limits) reduces overall taxable income but does not exempt Social Security itself.
State Taxes on Social Security Benefits: The Nationwide Overview
Unlike federal rules, state taxation of Social Security is far more retiree-friendly. As of 2026:
- 42 states + Washington, D.C. do not tax Social Security benefits at all.
- Only 8 states tax any portion of benefits—and even in those states, most lower- and middle-income retirees are fully or partially exempt.
This makes retirement relocation a powerful tax strategy for many.
The 8 States That Still Tax Social Security Benefits in 2026
Here are the only states that may tax Social Security, along with key exemptions (rules can be complex—always verify with your state tax agency):
- Colorado: Fully exempt for age 65+. Ages 55–64 may deduct benefits if AGI is below $75,000 (single) or $95,000 (joint).
- Connecticut: No tax if AGI is below $75,000 (single) or $100,000 (joint). Higher earners may owe on a portion.
- Minnesota: Full exemption if AGI is $84,490 or less (single) or $108,320 or less (joint). Graduated phase-out above those levels.
- Montana: Some benefits taxable above federal-like thresholds; seniors 65+ get a deduction starting at $5,500+ (inflation-adjusted).
- New Mexico: Exempt below approximately $100,000 (single) or $150,000 (joint) AGI, with retirement income deductions.
- Rhode Island: Modification/exemption available if you’ve reached full retirement age and AGI is under certain limits (around $81,900 single / $102,400 joint).
- Utah: Taxes the same portion as the federal government (up to 85%), but offers a retirement tax credit for many.
- Vermont: Graduated exemptions similar to federal base amounts; most lower-income retirees pay little or nothing.
West Virginia fully phased out its tax on Social Security in 2026. States like Kansas, Missouri, and Nebraska eliminated theirs in prior years.
Federal vs. State Taxes on Social Security: Key Differences
| Aspect | Federal Taxes | State Taxes (in the 8 taxing states) |
|---|---|---|
| Taxable Portion | Up to 85% based on combined income | Varies; often follows federal or offers bigger exemptions |
| Thresholds | Fixed since 1980s ($25k/$32k base) | Usually income- or age-based (higher or more generous) |
| Applies Nationwide | Yes | Only 8 states |
| Recent Changes | None (still taxable) | Many states recently eliminated or reduced taxes |
| Impact on Retirees | Affects everyone with moderate income | Minimal or zero for most retirees |
The biggest difference: Most Americans pay federal tax on a portion of benefits but zero state tax, regardless of where they live.
How to Calculate and Report Taxes on Your Social Security Benefits?
- Receive your Form SSA-1099 in January.
- Calculate combined income.
- Use IRS Worksheet 1 (Pub. 915) for federal taxable amount.
- Check your state return instructions—many start with federal AGI and then subtract Social Security if exempt.
- Consider tax withholding from benefits (Form W-4V) to avoid underpayment penalties.
Smart Strategies to Minimize Taxes on Social Security
- Manage combined income: Delay large withdrawals from 401(k)s/IRAs or convert to Roth in low-income years.
- Relocate strategically: Move to one of the 42 non-taxing states if state taxes are a concern.
- Use the new senior deduction: Eligible 65+ taxpayers can reduce AGI by up to $6,000 (phases out above $75k/$150k).
- Tax-efficient investments: Favor tax-free municipal bonds or Roth accounts.
- File jointly when beneficial: Married couples get higher thresholds.
- Consult a tax professional: State rules change and individual situations vary.
Final Thoughts: Planning Ahead for 2026 and Beyond
