Tax records mailing address incorrect, how do I find them?

[Trey Foradory]

One of my mail pieces I sent from driving for dollars was returned as "Vacant".  I sent the marketing piece to the address listed in the tax records but apparently this address is incorrect.  What is the best way to find the correct address?  I've read a little about skip tracing but have never done this before.  Any and all advice is more than welcomed.  Thanks in advance and hope everyone is enjoying their day.
