<prompt> Human: Well my wife said I should try it in order to keep tabs on my credit score, so last night I did. To my dismay I saw 2 Federal Tax Lien on my report, one that states that I owe 23k, and another that says that I owe 76kI am honestly baffled and confused what a Federal Tax Lien is and why it says that I owe so much. Up until a year and a half ago I had been working simple minimum wage jobs and never a full 40 hours a week, never owned any property or a car, never had any outstanding bills or anything medical... Ive honestly been living a very simple life. Work part time, and rent an apartment, and use a bus system to commute. It wasnt until 2 income taxes ago that I started making any real money, but my life is still simple and property free still no vehicle. Honestly the only thing that I can think of is that this is an error and that this report is meant for my dad. We share the same name, except I am the 2nd, and we have had them get us mixed up before. Back in 2013 I got a letter stating that I owe 12k in taxes, but upon investigation I came to find out that that was meant for my dad. Now all of a sudden I owe close to 100k in just 3 - 4 years later? If I really owed that much then wouldnt I have not gotten tax refunds all these years? Who do I call to clarify all of this mess? Im honestly very worried, even though Im sure they have the wrong guy..  <response>: Tl;Dr - dont give your kid the same name as you unless you want to cause problems for them in the future.
