Yes, however you can only contribute to one at a time. Also you can’t go over your annual contribution amount. If you are contributing to an HSA through your employer, you’ll need to only contribute to that one during your plan year.
Individual contributions are capped by the IRS at $3750 for individuals and $6900 for families.
Note: You can’t have a “joint account” with a spouse or significant other, you’ll just have the one account associated from that employee (you or your spouse). Money in the HSA can be spent on anyone in your household, spouses and kids alike.
