More advisors are becoming interested in offering health savings accounts (HSAs) to their clients' employees, along with the employer-sponsored retirement plan. Additionally, advisors see the logic of a financial professional dealing with the investment angle of an HSA. Yes, although much has been made of HSAs as a saving-then-spending vehicle for health care, they are also an investment tool, and a way to prepare for health care expenses in retirement. Of course, there are rules and regulations around HSAs, just as with 401(k)s and other employee benefits. Typically it's up to the employer to oversee the compliance aspect. But knowing a little about various compliance issues and questions can help expand an advisor's value proposition.
