State Tax Bill

A few months ago, I received a letter from the Louisiana Department of Revenue (LDR) claiming that I had unpaid taxes for 2022. Since I haven’t lived or worked in Louisiana since 2018, I initially dismissed it as a clerical error.

However, yesterday I received another letter from the LDR, this time with detailed numbers. The letter claims I owe $5,400 in back taxes. Given that I haven’t had any connection to Louisiana in over six years, I’m at a loss as to why I’m being issued this bill.

Has anyone else encountered a similar issue with the LDR (or any state)? If so, how did you go about contesting it? Any advice or insights would be greatly appreciated.
