Surprise! You may owe the IRS money because of a ‘math error’
If you get a letter from the IRS that says you owe money because of a math error, pay attention. You could get one of four kinds of letters: CP 11, CP 12, CP 13, or letter 6470. None of them is likely to contain good news.
The Taxpayer Advocate Service says 9 million Americans have gotten notices from the IRS that say the government is billing them for payment due to a “math error.” 7.4 million of the errors were due to pandemic-era stimulus overpayments.
But wait, there’s more.
