The IRS issued more than 105 million individual refunds averaging $3,138 each in the most recent filing season — yet millions of Americans collecting only Social Security never submitted a return, assuming they had nothing to gain. That assumption is often correct. But not always. If Social Security benefits were your only income, your benefits are generally not taxable and you probably do not need to file a federal income tax return. The word “probably” carries enormous weight for anyone with a part-time job, a marketplace health plan, or a refundable credit situation. This article walks through every scenario where a Social Security recipient might — or might not — see a refund in .
📋 Key Takeaway
If Social Security is your only 2026 income, you likely owe $0 in federal tax and face no legal obligation to file. But if you had any earned wages, paid marketplace insurance premiums, or qualify for a refundable credit, filing could generate a real refund — even if you owe nothing.

The default assumption
Most people assume Social Security recipients never file taxes. That assumption costs real money. Three specific situations generate actual refunds even when Social Security is your only income source.
First, federal income tax withholding. If you asked SSA to withhold taxes from your benefit checks using Form W-4V, those withholdings may exceed your actual tax liability. The IRS refunds the difference.
Second, refundable tax credits. Unlike deductions, refundable credits pay out even when your tax bill is zero. The Earned Income Tax Credit (EITC) requires earned income, so Social Security alone disqualifies most recipients. However, other refundable credits may still apply depending on your household.
Third, prior-year tax adjustments. If you received a lump-sum Social Security payment covering multiple prior years, a special lump-sum election method under IRS Publication 915 can reduce your taxable amount significantly. Source: irs.gov Publication 915.

The IRS uses combined income to determine how much of your Social Security is taxable. The formula is straightforward.
If Social Security is truly your only income, your AGI is zero. Your combined income equals only 50% of your annual benefit. Here is what the thresholds mean in practice for :
| Filing Status | Combined Income Threshold (0% taxable) | Up to 50% Taxable | Up to 85% Taxable |
|---|---|---|---|
| Single / Head of Household | Below $25,000 | $25,000–$34,000 | Above $34,000 |
| Married Filing Jointly | Below $32,000 | $32,000–$44,000 | Above $44,000 |
| Married Filing Separately | $0 | Any amount | Varies |

SSA allows you to request voluntary withholding at flat rates: 7%, 10%, 12%, or 22%. You submit Form W-4V directly to your local Social Security office.
Here is a real-world example. Suppose you receive $1,800/month in Social Security. You elected 10% withholding. SSA withheld $2,160 during . But your actual tax liability is $0 because your combined income is below $25,000. The IRS owes you the entire $2,160 back as a refund.
You must file Form 1040 to claim it. The refund does not arrive automatically. Many recipients leave this money unclaimed simply because they believe filing is unnecessary.
The standard filing deadline for returns is . You have three years from that date to claim a refund before it expires permanently. Source: IRS Topic No. 301.
