Need to get your client thinking about their U.S. tax risk? Try these tips.

If you have American-born clients, check in with them to make sure they understand their U.S. tax obligations. If they haven’t been filing down south, or if they own a business or trust, bring in a tax professional to help them sort through whether they owe anything to Uncle Sam. Further, stay attuned to hints a client may have U.S. ties and ask the right questions to ensure he or she won’t pass the “American test.”
