Who This Guide Is For
This guide is designed for:
- Current Social Security recipients: Those already receiving benefits who want to reduce their tax burden
- Soon-to-be retirees: People within 5 years of claiming Social Security who want to plan ahead
- Working retirees: Those collecting benefits while still earning income
- High-income retirees: Those with significant retirement income from multiple sources
- State-movers: Retirees considering relocating to reduce their tax burden
If you receive Social Security benefits or will soon, this information could save you thousands of dollars annually.
Step 1: Understand How Social Security Is Taxed
Many retirees are surprised to learn that Social Security benefits can be taxable. The amount of your benefits subject to federal income tax depends on your "combined income," also called provisional income.
Combined Income Formula
Combined Income = Adjusted Gross Income (AGI) + Nontaxable Interest + 50% of Social Security Benefits
Once you calculate your combined income, here is how much of your Social Security becomes taxable:
Single Filers
- Below $25,000: Benefits are not taxable
- $25,000 - $34,000: Up to 50% of benefits may be taxable
- Above $34,000: Up to 85% of benefits may be taxable
Married Filing Jointly
- Below $32,000: Benefits are not taxable
- $32,000 - $44,000: Up to 50% of benefits may be taxable
- Above $44,000: Up to 85% of benefits may be taxable
Important note: These thresholds have not been adjusted for inflation since 1984. As a result, more retirees than ever now pay taxes on their Social Security benefits. Approximately 56% of recipients now pay some federal tax on their benefits.
Step 2: Calculate Your 2025 Social Security Tax
Let us walk through a real calculation to see how this works in practice.
Example: Robert and Linda - Married Retirees
Income sources:
- Social Security benefits: $42,000
- Pension income: $24,000
- IRA withdrawals: $15,000
- Tax-exempt municipal bond interest: $5,000
Combined Income Calculation:
- AGI (pension + IRA): $39,000
- Nontaxable interest: $5,000
- 50% of Social Security: $21,000
- Combined income: $65,000
Since $65,000 exceeds $44,000, up to 85% of their Social Security is taxable.
Taxable Social Security: $42,000 x 85% = $35,700
At the 22% tax bracket, they owe approximately $7,854 in federal taxes just on their Social Security benefits.
This example shows how quickly Social Security taxes can add up, even for retirees with modest incomes. The key is understanding these thresholds and planning around them.
Step 3: Know Your State Tax Situation
Federal taxes are only part of the picture. State taxation of Social Security varies dramatically, and your state of residence can significantly impact your total tax burden.
States That Do Not Tax Social Security (2025)
The following 41 states and Washington D.C. do not tax Social Security benefits at all:
- No state income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming
- Exempt Social Security: Alabama, Arizona, Arkansas, California, Delaware, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Mississippi, Nebraska, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Virginia, Wisconsin, Washington D.C.
States That Tax Social Security (with Exemptions)
The following 9 states tax Social Security but offer exemptions or deductions:
Colorado
Full exemption for those 65+. Partial exemption for ages 55-64.
Connecticut
Exempt if AGI is below $75,000 (single) or $100,000 (married). Partial exemption above those levels.
Kansas
Exempt if federal AGI is $75,000 or less.
Minnesota
Partial exemption based on income. Full exemption at lower income levels.
Missouri
Exempt if AGI is below $100,000 (single) or $150,000 (married).
Montana
Follows federal rules for taxation. Partial deduction available.
New Mexico
Exempt if income is below $100,000 (single) or $150,000 (married).
Rhode Island
Exempt if federal AGI is below $101,000 (single) or $126,250 (married).
Vermont
Exempt if AGI is below $50,000 (single) or $65,000 (married). Partial exemption above those levels.
West Virginia
Phasing out taxation by 2026. Currently offers significant exemptions.
If you live in a state that taxes Social Security and your income exceeds the exemption thresholds, you could owe an additional 3-6% in state taxes on your benefits.
Step 4: Implement Tax-Reduction Strategies
Now that you understand how Social Security is taxed, here are proven strategies to reduce your tax burden:
Strategy 1: Manage Your Withdrawals
Control the timing and amount of retirement account withdrawals to stay below the taxable thresholds. If your combined income is close to a threshold, reducing IRA withdrawals by even a few thousand dollars could keep more of your Social Security tax-free.
Strategy 2: Consider Roth Conversions Early
If you are not yet collecting Social Security, consider converting traditional IRA funds to a Roth IRA. Roth withdrawals do not count toward your combined income calculation. Pay taxes on the conversion now, and enjoy tax-free income (that does not trigger Social Security taxes) later.
Strategy 3: Time Your Social Security Claim
Delaying Social Security until age 70 increases your benefit by 8% per year after full retirement age. But it also gives you time to draw down traditional retirement accounts while in a lower tax bracket, reducing future combined income.
Strategy 4: Use Tax-Exempt Investments Strategically
Municipal bond interest is tax-exempt but still counts toward your Social Security combined income calculation. If you are over the threshold anyway, muni bonds still make sense. But if you are close to the threshold, their inclusion in the calculation could push you over.
Strategy 5: Consider Your State of Residence
If you are flexible about where you live in retirement, choosing a state that does not tax Social Security can save thousands annually. Combined with no state income tax states, you could eliminate state taxes entirely.
Step 5: Plan for Required Minimum Distributions
Starting at age 73 (or 75 for those born in 1960 or later), you must take Required Minimum Distributions (RMDs) from traditional retirement accounts. These distributions count as income and can significantly increase your Social Security tax burden.
RMD Planning Strategies
- Qualified Charitable Distributions (QCDs): If you are 70.5 or older, donate up to $105,000 directly from your IRA to charity. The distribution satisfies your RMD but does not count as taxable income.
- Early withdrawals: Consider taking distributions before RMDs are required to reduce account balances and future mandatory distributions.
- Roth conversions: Convert traditional IRA funds to Roth before RMDs begin. Roth accounts have no RMDs during your lifetime.
Pro Tips and Warnings
Pro Tips
- Use the "Roth bridge" strategy: Live on Roth withdrawals in early retirement to let Social Security grow and avoid early taxation
- Bunch deductions in alternating years to maximize itemizing when your income is higher
- Consider the additional standard deduction for those 65+: $1,950 (single) or $3,100 (married, both 65+)
- Review your withholding annually as income sources change in retirement
Warnings
- Do not forget that municipal bond interest counts toward the Social Security combined income calculation
- Selling investments for a capital gain can push you over the threshold in that year
- Inherited IRAs now have a 10-year distribution rule that can spike income unexpectedly
- State tax laws change frequently - verify current rules before making decisions
Common Mistakes to Avoid
- Ignoring the cliff effect: Going just $1 over the threshold can make thousands more in benefits taxable
- Not planning for RMDs: Future RMDs can dramatically change your tax situation
- Assuming Social Security is tax-free: Many retirees are surprised by their first tax bill
- Moving states without tax planning: Research state tax rules before relocating
- Withdrawing too much too early: Large early withdrawals can result in years of higher taxes
