Tax liens used to show up on your credit report, but they no longer do. Until 2017, unpaid tax liens stayed on your credit report for up to 10 years. If you paid a lien, it still hung around on your credit report for up to 7 years.
But there were issues with the accurate reporting of liens. In some cases, individuals with flawless payment histories had someone else’s lien incorrectly noted on their credit report. So the three major credit bureaus – Equifax, Experian and TransUnion – removed all tax liens from credit reports by April 2018.
