I owe back taxes, however, how do I find out if there is a tax lien against me? I am looking to purchase a home and not sure if the taxes owed will allow me to?

I have back taxes from the last couple years- I am trying to purchase a house, however, I wanted to find out if a tax lien has been placed on me? I have not received anything in the mail stating it has, however, trying to see if the back taxes will hinder me from purchasing a house
