Just the Tip:
A health savings account lets your money go in untaxed, grow untaxed, and come out untaxed when you spend it on medical care. If your health plan qualifies, fund it every year, invest the balance, and pay small medical bills out of pocket so the account keeps compounding.
No 401(k), IRA, or 529 plan does all three. A traditional 401(k) taxes what you take out, and a Roth IRA or 529 plan gives no federal deduction for what you put in.
Most owners use only two of the three. In the Employee Benefit Research Institute’s database of 15.2 million HSAs, only 18% of account holders invested their balance in 2024, and more than half made withdrawals.
Unspent money carries over year after year and stays yours when you change jobs. Invested, it can grow for decades, and none of that growth is taxed if it eventually pays for medical care.
So pay today’s medical bills from checking if you can, and save every receipt. The IRS sets no time limit on reimbursing yourself tax-free for qualified expenses you had after opening the account, as long as you keep the records.
Contribute through payroll if your employer offers it. Those contributions also skip Social Security and Medicare taxes, a break you lose by depositing on your own and deducting it later. Aim for the annual IRS limit. Invest whatever you won’t need soon in a low-cost fund, or move the balance to an HSA provider that offers one.
At 65, the 20% penalty on non-medical withdrawals disappears. Spending on anything else is then taxed like a traditional IRA withdrawal, while medical spending stays tax-free.
To contribute, you need a high-deductible health plan and can’t be on Medicare. Bronze and catastrophic individual-market plans also count as of Jan. 1, 2026, even when their deductibles miss the usual rules.
If your plan qualifies, fund the HSA right after you capture any 401(k) match.
