He Owes the IRS Back Taxes. It Can Take 15% of His Social Security, and Most Retirees Don’t Know It

A 70-year-old retiree opens a letter from the IRS and learns his monthly Social Security check is about to shrink. He owes back federal income taxes from years he filed late and never paid in full. What stuns him is the line explaining that the government can take a slice of his Social Security to satisfy the bill. I thought Social Security was untouchable, he tells his daughter. He is right about most debts. Federal tax debt is the exception.

This situation is more common than retirees think. Social Security is the single largest transfer program in the country, with $1.6 trillion flowing to households for all of 2025. When a retiree carries old tax debt into retirement, that monthly check becomes the most reliable thing the IRS can reach.

The rule almost everyone gets half right

Section 207 of the Social Security Act shields benefits from nearly every creditor a retiree might encounter. Credit card companies cannot garnish a retiree’s check. Medical collectors cannot touch it. Personal loan servicers, car repo lawyers, and private debt buyers all hit the same wall. If someone’s benefits land in a bank account by direct deposit, financial institutions are required to protect a baseline of recent deposits from most garnishment orders.

The exception is the federal government itself. Through the Federal Payment Levy Program, the IRS can levy up to 15% of a monthly Social Security benefit to collect unpaid federal income taxes. Supplemental Security Income, the needs-based program, is off limits. Regular retirement, survivor, and disability benefits can all be levied.

For our 70-year-old, a $2,000 monthly benefit becomes roughly $1,700 after the levy kicks in. That $300 difference, every month, for as long as the debt sits unresolved, is the part most retirees never see coming. The 2.8% 2026 cost-of-living adjustment (COLA) does not undo it. The levy applies to the new, higher benefit too.

Why this matters more than it once did

Households have less cushion than they did a couple of years ago. The personal savings rate has slid from 6.2% in early 2024 to 2.6% in April 2026. Credit card interest rates are sitting at 21%, and 3% of card balances are delinquent. A retiree losing a piece of Social Security to a tax levy often cannot make up the gap by leaning harder on credit without compounding the problem.

Back taxes are not the only federal exception. Child support and alimony orders, defaulted federal student loans, and other non-tax federal debts can also reach Social Security, with different rules and caps. The levy program is the one that catches retirees most often, because tax debt tends to sit quietly for years before collections ramp up.

What actually fixes it

The levy is not permanent. Once a taxpayer is in an active arrangement with the IRS, the agency can release it. The retiree has four realistic paths:

1. Installment agreement. A monthly payment plan based on what he can afford. Once in place and being honored, the Social Security levy generally comes off.
2. Offer in compromise. A settlement for less than the full balance when the IRS agrees the full amount is not collectible over a reasonable period. Retirees on fixed income are often candidates.
3. Currently Not Collectible status. If paying anything would leave him unable to cover basic living costs, the IRS can pause collection entirely. Interest still accrues, but the levy stops.
4. Low Income Taxpayer Clinic or enrolled tax professional. These clinics represent qualifying taxpayers for free or low cost, and a good professional often negotiates a better outcome than a retiree handling it alone.

The takeaway

The hardest mistake to undo here is silence. Ignoring IRS notices moves a tax debt from a letter into a levy on the one check a retiree counts on. Picking up the phone, even years late, almost always produces a better result than waiting. Social Security is well protected from the outside world. It is the federal government you have to address directly, and the sooner that conversation starts, the smaller the bite from each month’s check tends to be.

Every tax situation has its own wrinkles, and the right path depends on income, assets, and how old the debt is. A short call with a qualified tax professional or a Low Income Taxpayer Clinic is usually the cheapest money a retiree in this spot will ever spend.
