Many consumers are unaware that not paying your taxes can result in a tax lien being reported on your profile, thanks to the credit-reporting agencies.

A tax lien is typically considered a negative item in a credit score and remains on your credit report seven years from the date the tax liability is resolved — or longer, if it’s not resolved. The specific point impact a tax lien has on a credit score will depend on the tax lien information reported, as well as the other information contained in the credit report.

However, the impact is greatest when the tax lien is recent and where the consumer has no other negative items (missed payment, high credit card balances, etc.) being reported. In these cases, the tax lien can drop the score by 100 points or more.
