If I give my husband rights to publish my book, can he do so under his account? Can he do so with my name as the pen name, too? Just wondering because I don't want to open a KDP account myself.
You would be VERY wise to publish under your own account.
Absolutely. If you don't trust your husband, a separate publishing account is not really the first precaution you should take!
As others have suggested, a publishing account is tied to an individual's tax ID number (for an American, usually the Social Security Number). If you file taxes jointly, it hardly matters, but if for reasons of pride you want it to be your name, the IRS really wouldn't care. All it wants is money; it doesn't care whose name is on the check (as I was told by my trust attorney when I was winding up a trust). The only place where you might want to reconsider this is with respect to FICA taxes -- again, if you are a US resident. If you have a job, it might be advantageous to have FICA taxes deposited in your own name. But if self-publishing is your only income, be aware that for FICA you get only one quarter credit for $1200, so it takes $4800 a year to get credit for the full year, and very few KDP publishers earn that much.
Indeed, there are circumstances in which reporting small FICA earnings ($400 is the breakpoint where one must file the FICA form) would actually reduce your eventual Social Security payments (because it is based on your average earnings over the employed years).
