How does IRS tax debt affect my credit score?

IRS tax debt itself doesn't directly appear on your credit report, but a federal tax lien does. When the IRS files a Notice of Federal Tax Lien (NFTL) with your county recorder, it becomes public record. While the three major credit bureaus stopped including tax liens on credit reports in 2018, many lenders and financial institutions still check public records directly. A tax lien can: make it nearly impossible to get a mortgage, prevent you from refinancing your home, block business loans and lines of credit, affect your ability to rent an apartment, and in some professions, threaten your security clearance or professional license. Under the Fresh Start Program, the IRS will withdraw a lien once you've paid the debt in full, or in some cases, will withdraw it when you enter into a Direct Debit Installment Agreement. Getting the lien withdrawn (not just released) is important because withdrawal removes the public record entirely.
