the HSA trustee will send the IRS info denoting your contribution to your HSA account. you would have to report it in your joint return on form 8889 for yourself. since it's not on your w-2 you can't show it as employer contribution which leaves the issue as to where to report it on the tax form. the HSA showing up on your husband's w-2 would flow to his form 8889 but the IRS will have no record from an HSA trustee that he actually contributed. There is no such thing as a joint HSA. as a result the IRS computers will likely kick out a notice. if you are performing services for the corp you should be getting your own w-2 so the HSA contribution can be reported properly. if you are not getting compensated that too can create an issue. you may want to consult with a tax professional before filing
