How to Reduce Taxes on Social Security Benefits in 2026
⏱ 8 min read · 1,505 words
If you're already collecting Social Security or planning to start soon, you might be shocked when you file your first tax return and see how much of your benefit is taxable. Up to 85% of your Social Security can be subject to federal income tax, depending on your other income. That's not a mistake. That's the law.
Most retirees assume Social Security is tax-free because they already paid payroll taxes on that money for decades. It doesn't work that way. If your combined income crosses certain thresholds, the IRS taxes a portion of your benefit as ordinary income. And if you're also taking required minimum distributions from a traditional IRA or 401(k), those withdrawals can push you into a higher bracket and trigger even more tax on your Social Security.
This article walks through four specific strategies to reduce taxes on Social Security benefits. Some take advance planning. Some you can implement this year. All of them are legal, straightforward, and worth understanding before you make irreversible decisions about when to claim or how to manage retirement withdrawals.
How Social Security Taxation Actually Works
The IRS uses something called "combined income" to determine how much of your Social Security is taxable. Combined income is your adjusted gross income (without Social Security), plus any tax-exempt interest from municipal bonds, plus half of your Social Security benefit.
Here's how the thresholds work for 2026:
- Single filers with combined income below $25,000: Zero tax on Social Security.
- Single filers between $25,000 and $34,000: Up to 50% of benefits are taxable.
- Single filers above $34,000: Up to 85% of benefits are taxable.
- Married filing jointly below $32,000: Zero tax on Social Security.
- Married filing jointly between $32,000 and $44,000: Up to 50% of benefits are taxable.
- Married filing jointly above $44,000: Up to 85% of benefits are taxable.
Most people assume the 85% threshold is high. It's not. If you're collecting $30,000 a year in Social Security and withdrawing $40,000 from a traditional IRA, you're well into the 85% zone. That means $25,500 of your Social Security becomes taxable income on top of the $40,000 IRA withdrawal.
Delay Claiming Social Security Until Age 70
The single most effective way to reduce lifetime taxes on Social Security is to delay claiming until age 70 and live on other income sources in the meantime. This strategy works for two reasons.
First, delaying increases your monthly benefit by roughly 8% per year between your full retirement age and age 70. If your full retirement age benefit is $2,400 a month, waiting until 70 gets you about $2,976 a month instead. That's $6,912 more per year for the rest of your life.
Second, delaying lets you drain taxable retirement accounts during your 60s when your income is lower and you're not yet taking Social Security. According to Fidelity's planning research, retirees who delay Social Security and strategically withdraw from traditional IRAs during this window can significantly reduce the percentage of their Social Security that becomes taxable later.
Take someone who worked 32 years in hospital administration and retired at 63 with $450,000 in a traditional 401(k). If she starts Social Security at 62 and takes small IRA withdrawals to supplement it, she'll pay tax on 85% of her Social Security every year. If instead she lives entirely on IRA withdrawals from 63 to 70, she empties a large portion of that taxable account before Social Security starts. Once Social Security begins at 70, her combined income stays below the 85% threshold because she's taking much smaller IRA withdrawals.
This approach also reduces required minimum distributions later. The less money sitting in a traditional IRA at age 73, the smaller your RMDs and the less they push up your taxable income.
Convert Traditional IRA Money to a Roth IRA Before Age 70
Roth conversions are one of the most underused tools for managing Social Security taxes. When you convert money from a traditional IRA to a Roth IRA, you pay ordinary income tax on the converted amount in the year you do it. After that, the money grows tax-free and comes out tax-free in retirement.
Here's why that matters for Social Security taxes: Roth IRA withdrawals don't count toward your combined income. Traditional IRA withdrawals do.
If you're in your early 60s and not yet collecting Social Security, you have a narrow window to convert chunks of your traditional IRA at relatively low tax rates. You'll pay tax on the conversion, but you're doing it in years when your income is lower because Social Security hasn't started yet.
The math changes for everyone, but a common approach is to convert enough each year to stay within the 22% or 24% federal bracket. Once you hit 70 and start Social Security, those Roth withdrawals keep your combined income lower and reduce how much of your Social Security gets taxed.
Most people assume Roth conversions are only for wealthy retirees. That's not true. Conversions work especially well for middle-income retirees with $200,000 to $600,000 in traditional retirement accounts who want to avoid big RMDs later.
Claim the New $6,000 Senior Tax Deduction for 2026
Starting in 2026, taxpayers over age 65 can claim an additional $6,000 deduction on their federal return. This deduction is temporary and part of recent budget legislation. It's available to seniors with income below certain thresholds.
According to analysis from the Tax Policy Center, the deduction benefits fewer than half of older adults because many seniors either have income too low to benefit significantly or income high enough to phase out of eligibility. The biggest impact is for seniors earning between roughly $80,000 and $130,000.
If you're in that range, the $6,000 deduction reduces your taxable income and can keep you below the thresholds where more of your Social Security becomes taxable. It's not a planning strategy on its own, but it's worth claiming if you qualify. Your tax software or preparer should automatically apply it if you're over 65.
Use Qualified Charitable Distributions to Lower Your AGI
If you're 70½ or older and charitably inclined, qualified charitable distributions let you send up to $105,000 per year directly from your traditional IRA to a qualified charity. The distribution counts toward your required minimum distribution, but it doesn't show up as taxable income on your return.
That matters because it lowers your adjusted gross income, which lowers your combined income, which reduces how much of your Social Security gets taxed. If your RMD is $18,000 and you send $10,000 of it as a QCD to your church or a nonprofit, only $8,000 counts as taxable income.
This strategy works best if you were planning to donate anyway. It doesn't make sense to give away money just to avoid taxes unless the charity matters to you. But if you're already writing checks to nonprofits, routing that money through a QCD saves you more in taxes than taking the distribution and then deducting the donation.
Plan Around Spousal Benefits and Catch-Up Contributions
Two additional planning considerations deserve mention, especially if you're still working part-time or have a non-working spouse.
If one spouse never worked or earned very little, spousal Social Security benefits for a non-working spouse can be up to 50% of the higher earner's full retirement age benefit. Those spousal benefits are taxed the same way as regular benefits, so the combined income thresholds still apply. The key is timing. If the higher earner delays until 70, the non-working spouse can claim a spousal benefit earlier without reducing the primary earner's benefit.
For those still working and over 50, catch-up contribution rules for 401(k) plans in 2026 allow an extra $7,500 on top of the standard $23,000 limit. If you're 50 to 59, that's $30,500 total. If you're 60 to 63, a new rule allows up to $11,250 in catch-up contributions for a total of $34,250. Contributing more now reduces your taxable income during working years and can slightly delay when you need to tap retirement accounts later.
Finally, if you're thinking ahead about leaving money to grandchildren, Roth conversions done now create tax-free inheritance later. Roth IRAs pass to beneficiaries without triggering income tax, which makes them one of the cleanest ways to leave money to grandchildren tax-free. Traditional IRAs force beneficiaries to pay ordinary income tax on every dollar they withdraw.
What This Means for Your Next Move
Reducing taxes on Social Security isn't about one trick. It's about coordinating when you claim benefits, how you withdraw from retirement accounts, and whether you convert taxable money to tax-free money during the years when your income is lower.
If you're not yet 70 and still deciding when to claim Social Security, run the numbers on delaying. If you have a sizable traditional IRA or 401(k), talk to a tax advisor about Roth conversions during your 60s. If you're already collecting Social Security and taking RMDs, look at qualified charitable distributions if you donate regularly.
Your my Social Security account at SSA.gov shows your estimated benefit at different claiming ages. IRS Publication 915 explains Social Security taxation in detail if you want the official rules. But the core principle is simple: the less taxable income you have from other sources, the less of your Social Security gets taxed. Plan accordingly.
