Is your company paying part of the deductible? I can’t get an HSA-qualifying plan with deductible under $6000. Also single and old.

Once you hit 65, you can withdraw HSA funds for any purpose, tax free, like a Roth IRA. 401k withdrawals will be taxed as ordinary income, so an HSA dollar is worth about $1.20 in a 401k.

When I was looking for a non-employer HSA, there’s a lot of providers out there with not-exactly-predatory terms. All kind of fees or restrictions that you wouldn’t find on other types of checking/saving/brokerage accounts. I ended up a Lively, but they added some investment/transfer fees when Schwab bought Lively’s investment partner TDA.

I suspect it’s partly because most HSA are determined by the employer, so someone in HR can be induced to choose a fee-laden plan if it’s easier for them, and partly because the tax benefits are so great that it still makes sense even after paying a $20 junk fee here and there.
