The Health Savings Account (HSA): Tax Treatment, HDHP Rules, 2025 Limits and 2025 Law Changes
In Short
A Health Savings Account (HSA) is a tax-exempt account that people covered by a high-deductible health plan use to pay or save for qualified medical expenses. It is commonly used by employees, self-employed people and business owners because contributions, growth and qualified withdrawals can all avoid federal income tax.
TL;DR
- Contributions are deductible (or excluded from income if made by an employer), earnings grow tax-free and distributions for qualified medical expenses are tax-free [1].
- For 2025 the contribution limit is $4,300 for self-only coverage and $8,550 for family coverage, plus $1,000 at age 55 or older [1].
- Eligibility requires high-deductible health plan coverage, no other disqualifying coverage, no Medicare enrollment and not being someone else's dependent [1].
- The 2025 law made the telehealth exception permanent and, from 2026, treats bronze and catastrophic Exchange plans as HSA-compatible and allows certain direct primary care arrangements [2][3][4].
Quick Facts
| Legal Reference | IRC §223 |
|---|---|
| Complexity | Low |
| Audit Risk | Low |
| Setup Cost | Low — an HSA account with a bank or other trustee |
| Time to Implement | Days — open an account once HDHP coverage is in place |
| Illustrative Example | Illustrative example, not a projection. A self-employed person with family HDHP coverage for all of 2025 contributes $8,550 to an HSA and deducts it on Form 8889. The money is invested, and years later it is used to pay medical bills tax-free. Actual results depend on the facts, investment returns and the tax rates involved. |

What Is a Health Savings Account?
A Health Savings Account is a tax-exempt trust or custodial account set up with a qualified trustee, such as a bank, to pay or reimburse qualified medical expenses [1][2]. To contribute, a person must be covered by a high-deductible health plan (HDHP) on the first day of the month, have no other disqualifying health coverage, not be enrolled in Medicare and not be claimable as a dependent on someone else's return [1].
HSAs are often described as having a triple tax advantage. Contributions an individual makes are deductible whether or not the person itemizes, and employer contributions are excluded from income; earnings in the account are not taxed while they stay there; and distributions used for qualified medical expenses are tax-free [1]. Unused money carries over from year to year, and the account belongs to the individual [1].
The One Big Beautiful Bill Act (Public Law 119-21) expanded HSA eligibility. It made permanent the rule that telehealth and other remote care can be covered before the deductible without ending HSA eligibility, for plan years beginning on or after January 1, 2025 [3][4]. Starting January 1, 2026, bronze and catastrophic plans available as individual coverage through an Exchange are treated as HDHPs, and people in certain direct primary care arrangements can contribute to an HSA and pay the periodic fees from it tax-free [2][3][4]. Treasury and the IRS issued Notice 2026-05 with guidance [3].
How Does a Health Savings Account Work?
- The person enrolls in a qualifying HDHP — through an employer, an Exchange or on their own — and confirms no other disqualifying coverage [1].
- An HSA is opened with a trustee or custodian; contributions can come from the person, an employer or anyone else on the person's behalf [1].
- Total contributions stay within the annual limit for the coverage type, plus the $1,000 catch-up at 55 or older [1].
- Money is spent on qualified medical expenses or left in the account to grow; distributions are reported on Form 8889 [1].
- Records showing that distributions paid for qualified medical expenses are kept with the tax records [1].
The Good: What Are the Benefits of a Health Savings Account?
- Contributions reduce taxable income, growth is not taxed in the account and qualified withdrawals are tax-free [1].
- Balances carry over every year, and the account stays with the person after a job change [1].
- After age 65, withdrawals for non-medical purposes are taxed as income but are not subject to the 20% additional tax [1].
- The 2025 law widened eligibility to telehealth, bronze and catastrophic Exchange plans, and direct primary care [3][4].
The Bad: What Are the Drawbacks of a Health Savings Account?
- Eligibility depends on HDHP coverage, which means higher out-of-pocket costs before the deductible is met [1].
- Enrolling in Medicare ends the ability to contribute [1].
- Annual limits cap how much can go in, and they are prorated for months without eligible coverage, subject to special rules [1].
- Some states do not follow the federal tax treatment of HSAs. State rules are not covered by the federal sources here.
The Ugly: What Are the Serious Risks of a Health Savings Account?
- Distributions not used for qualified medical expenses are included in income and generally face an additional 20% tax before age 65 [1].
- Excess contributions that are not withdrawn in time are subject to a 6% excise tax for each year they stay in the account [1].
- Losing documentation for past medical expenses can make earlier tax-free distributions hard to support in an examination [1].
Who Uses a Health Savings Account?
Who It's Commonly Used By
- Employees whose employer offers an HDHP and an HSA [1].
- Self-employed people and small-business owners who buy HDHP coverage [1].
- People who can pay medical costs from other funds and leave the HSA invested.
- From 2026, people in bronze or catastrophic Exchange plans and certain direct primary care arrangements [3][4].
What Are the Key Rules & Requirements for a Health Savings Account?
- The person must be covered by an HDHP on the first day of the month and have no other disqualifying coverage [1].
- For 2025, an HDHP has a deductible of at least $1,650 (self-only) or $3,300 (family) and an out-of-pocket maximum of no more than $8,300 or $16,600 [1].
- For 2025, contributions are limited to $4,300 (self-only) or $8,550 (family), plus $1,000 at 55 or older [1].
- Telehealth coverage before the deductible does not end eligibility for plan years beginning on or after January 1, 2025 [3][4].
- From 2026, bronze and catastrophic plans available as individual coverage through an Exchange are treated as HDHPs [2][3].
- From 2026, a direct primary care arrangement with fees of no more than $150 a month (twice that for more than one person) is not treated as a health plan [2].
- Form 8889 is filed for any year with HSA contributions or distributions [1].
What Are Common Mistakes & Red Flags With a Health Savings Account?
- Contributing after enrolling in Medicare [1].
- Contributing the family limit with only self-only coverage [1].
- Using HSA funds for non-medical purchases before age 65 [1].
- Not keeping receipts for medical expenses paid from the HSA [1].
- Assuming every plan with a high deductible is an HDHP without checking the IRS minimums and maximums [1].
