These aren't technically retirement accounts, but they offer several benefits that make them a good choice for your savings. Your contributions reduce your taxable income for the year, medical withdrawals are always tax-free, and, after age 65, you can make nonmedical withdrawals without penalty, although you will owe taxes on these.
In 2026, individuals can contribute up to $4,400 to an HSA ($4,300 in 2025). Families may contribute up to $8,750 in 2026 ($8,550 in 2025). Adults 55 and older can add another $1,000 to these limits for both 2025 and 2026.
If you don't have any other choices, consider a taxable brokerage account. You'll owe taxes on your contributions and your earnings, but if you hold your investments for a year or longer, your earnings become subject to long-term capital gains tax rather than income tax, which can save you money.
Remember, the definition of an HCE varies slightly from year to year, so if you're on the bubble, make sure you verify how much you can contribute to your 401(k) every year before you start putting away money. Talk to your company's HR department if you're not sure whether you're an HCE or how much you're allowed to contribute.
