Hi everyone. I registered a dba(doing business as) name in Buffalo back in like 2006 and also got a number for collecting sales tax, a TF and then 7 digits. This was all back in Buffalo over 10 years ago. Since then I lived in North Carolina for 7 years, and now am currently living in Maine. Would that same dba name and sales tax # still apply after all this time and switching states, or would I need to get new ones? If anyone knows about these things I would greatly appreciate letting me know. Thank you.
