What this letter means
A CP91 says the IRS plans to take up to 15% of your Social Security benefits to pay a tax debt. They do this with a computer program that works with the Treasury Department. The money comes out before your check reaches you.
This letter comes after an earlier final notice, usually a CP90, LT11, or Letter 1058. That notice is the one that gave you 30 days to ask for an appeal hearing. The CP91 is the last heads-up before your check gets smaller.
It applies to retirement and survivor benefits. It doesn’t take Supplemental Security Income (SSI), the program for people with very low income. Social Security disability isn’t taken automatically, either.
How urgent is it?
Very. A CP91 gives you about 30 more days to work things out. After that, the cut can start with a later payment. It keeps going each month until the debt is paid or resolved.
For someone on a fixed income, 15% can mean choosing between bills. The IRS often agrees to pause collection when the money is truly needed for basic living costs. But you have to ask and show your numbers.
What we do
We check the amount first. Don’t assume the amount is right. We pull your IRS records and look for mistakes before anything else.
We look at your real budget. If losing 15% would leave you short on rent, food, or medicine, we make that case. The IRS may mark your account as unable to pay for now, and stop the cut.
We push for the best way out. That could be a pause in collection, a payment plan you can keep, or settling for less if you qualify.
