She Paid $40,000 of Medical Bills From Checking Over 15 Years and Kept Every Receipt. At 68 She Pulled $40,000 Out of Her HSA Tax-Free in One Afternoon

Understanding any strategy allowed under health savings account rules is critical, especially when it involves paying medical bills out of pocket, keeping receipts, and reimbursing yourself from the HSA years later. In the scenario described in the headline, a saver paid about $40,000 in medical costs out of pocket over 15 years, roughly $2,667 per year. At 68, she recouped the full amount in a single transaction. Current federal rules permit every step of that plan, yet industry data suggests very few account holders follow it.

How an Old Receipt Becomes a Tax-Free Withdrawal

An HSA withdrawal is tax-free when it pays for, or reimburses, a qualified medical expense incurred after you established the HSA. The IRS sets no deadline for reimbursement. Publication 969 only requires records “sufficient to show” that the money went to qualified expenses. A bill from 15 years ago receives the same tax treatment as one paid back the week it arrived.

This rule, sometimes called the “shoebox strategy,” rests on a straightforward reading of IRS Publication 969: there is no time limit on retroactive reimbursement, as long as the expense was incurred after the account was opened, was not previously reimbursed elsewhere, and was not claimed as an itemized deduction on Schedule A. The burden of proof sits entirely with the account holder. Receipts never need to be mailed to the IRS or the custodian upfront; they become relevant only during an audit.

Clark Howard explained the rule on his podcast in April 2026. He noted that the withdrawal “doesn’t have to be withdrawn in the same year as the expense. You just have to have proof of the unreimbursed expenses you’ve had through the years.” The receipts are what convert an ordinary account distribution into a tax-free withdrawal.

Why Age 68 Changes the Tax Math

After age 65, non-medical HSA withdrawals no longer carry a penalty. They are simply taxed as ordinary income. A 68-year-old without receipts could take out $40,000, but that entire sum would count as taxable income for the year. With receipts, the same withdrawal is completely tax-free. In practical terms, the receipts are worth whatever marginal income tax she would otherwise have owed on $40,000.

Medicare also shapes the timing of this strategy. Once someone enrolls in Medicare, contributions to an HSA stop entirely. Medicare Part A coverage often starts retroactively, backdated up to six months, which can catch people off guard. By 68, a typical enrollee is exclusively in withdrawal mode. The account can still cover ongoing Medicare costs, including the $202.90 standard monthly Part B premium and the $283 annual Part B deductible for 2026.

Most Accounts Get Spent Almost as Fast as They’re Funded

Devenir’s year-end 2025 report counted 41.7 million accounts holding nearly $174 billion, a 19% jump in total assets from 2024, even as account growth held to a more modest 6%. During 2025, account holders contributed nearly $60 billion and withdrew nearly $45 billion, keeping about $15 billion in the system. For most people, the HSA functions like a checking account for doctor visits rather than a long-term savings vehicle. Devenir’s more recent midyear 2026 survey found assets had already climbed to nearly $192 billion across 42.6 million accounts, suggesting the growth trajectory is accelerating.

Debit card swipes made up 91% of all withdrawals in 2025, with an average transaction of $117. Only about 10% of accounts had any money invested, and 22% had a zero or negative balance at year-end. Invested accounts averaged $24,252 in combined deposits and investments, nearly 9.7 times the average funded account that kept money only in cash. Accounts opened in 2004 averaged $34,952, while accounts opened in 2025 averaged $2,181, a gap that reflects years of compounding in the older cohort.

These figures are averages, and a handful of large accounts pull them up significantly. Picture ten accounts holding $2,000 each alongside one holding $200,000. The average reads $20,000, but the typical account still has $2,000. With 1.7 million accounts above $25,000 and millions near zero, the median HSA is likely well below the averages Devenir reports. Devenir projects the market will surpass 49 million accounts and $246 billion in assets by the end of 2028, up from its earlier $234 billion forecast, as the midyear 2026 report revised the estimate higher.

A Credible Case Against Hoarding Receipts

Not everyone agrees the strategy is the best use of HSA dollars. A listener named Mike from Utah challenged Howard on a May 2026 episode. His argument: people who haven’t yet maxed out their Roth IRA and 401(k) should “reimburse your medical expenses every year and use that money to increase your Roth.” The logic is clean: Roth money can be spent tax-free on anything in retirement, while HSA money is tax-free only for qualified medical costs.

The strategy also requires consistent cash flow. Howard raised this point in 2018, asking a caller directly whether the household budget could absorb out-of-pocket medical costs without touching the HSA. Paying roughly $2,667 a year from a checking account while leaving the HSA untouched is straightforward for some households and genuinely difficult for others. The receipts only have value if the bills could be paid another way first.

What It Takes to Build the Same Balance

For 2026, the HSA contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, both up from the prior year. People 55 and older can add a $1,000 catch-up contribution, a figure fixed by statute and unchanged since 2009. At the family limit with a catch-up, a household where both spouses are 55 or older could deposit up to $10,750 combined across two separate HSAs.

The 68-year-old in the headline stands apart from the typical account holder in three concrete ways: she left the balance growing in the account rather than spending it down, paid her medical bills from other money each year, and kept meticulous records for a decade and a half. Devenir’s data suggests most HSA holders do none of those things. The tax advantage was available to all of them. The paper trail is what made it usable at the end.

Editor’s note: This update added Devenir’s midyear 2026 figures (42.6 million accounts, nearly $192 billion in assets) and its revised 2028 projection of $246 billion, up from the earlier $234 billion forecast. The 2026 Medicare Part B premium ($202.90) and deductible ($283), and the 2026 HSA contribution limits ($4,400 self-only, $8,750 family), were verified against IRS and CMS sources.
