Form 8889, Health Savings Accounts (HSAs)
A taxpayer must file Form 8889 with Form 1040 if the taxpayer (or spouse if filing a joint return) had any activity in an HSA. This is true even if only the taxpayer's employer or the spouse's employer made contributions to the HSA.
Taxpayers who are filing jointly and who each have separate HSAs will each complete a separate Form 8889. Married taxpayers cannot have a joint HSA.
Ask taxpayers during the interview process if their HDHP coverage is "self-only" or "family," and check the corresponding box on Form 8889.
