Can I open an investing account for a spouse who doesn't earn income?

Yes — a spousal IRA lets a non-working or low-earning spouse contribute to their own IRA based on the working spouse's income, as long as you file taxes jointly. For 2025 that's up to $7,000 (or $8,000 if 50+) into a Roth or traditional IRA in the non-earning spouse's name, effectively doubling the household's IRA savings. The account belongs entirely to that spouse, which also protects their retirement security and independence. Beyond the IRA, you can open a regular taxable brokerage account in their name or a joint account together with no income requirement at all. This is one of the most overlooked moves for single-income households — many couples don't realize the stay-at-home spouse can still build retirement savings.
