How much can I contribute to an HSA?

11/02/2017

For 2018, you can contribute the following amounts:

  • $3,450 if you have self-only coverage
  • $6,900 if you have family coverage
  • For those 55 and older, an additional $1000 “catch-up” contribution is allowed.

If you join an HDHP mid-year, there are special rules about how much you can contribute. To avoid possible complications, we recommend pro-rating your HSA contribution to not exceed the following monthly amounts:

  • $287.50 (1/12 of $3,450) if you have self-only coverage
  • $575 (1/12 of $6,900) if you have family coverage

So if you join an HDHP on October 1st, your HSA contributions should not exceed:

  • $862.50 if you have self-only coverage
  • $1,725 if you have family coverage

You are allowed to contribute more than the pro-rated amounts, but there can be negative tax consequences if your HSA eligibility changes.
