During the year of 2020, there were some tax filing business (Vietnamese) where some workers there stole their customer data and used for their personal purposes. I recently found out a couple guys who did that to our Vietnamese community. Sorry, I can't post their name on this post, however, beware of those.
Recently, some of my customers got tax ID theft from their tax preparers. If you receive an audit letter from the Internal Revenue Service to inform you of incomes that you don't recognize, you may got a Tax ID theft. You may have contact the IRS immediately to correct the problem.
