$2,600

2004 origin

Original self-only limit. Roughly $4,400 in 2026 dollars - the same as today's actual limit.

Triple tax advantage

Pre-tax in, tax-free growth, tax-free out for qualified medical. Unique among retirement accounts.

2026 self-only

$8,750 family under Rev. Proc. 2025-19. The separate statutory age-55 catch-up is $1,000.

The major changes

The HSA has been shaped by four major pieces of legislation: MMA 2003 (origin), HCERA 2006 (flexibility), ACA 2010 (OTC restriction), and CARES 2020 (OTC reversal).

2003

Medicare Modernization Act of 2003 creates the HSA

The Medicare Modernization Act (signed December 8, 2003) added Section 223 to the Internal Revenue Code, creating the Health Savings Account effective January 1, 2004. Eligibility required enrollment in a High-Deductible Health Plan (HDHP) and no other disqualifying health coverage. The original 2004 self-only contribution limit was $2,600 ($5,150 family), with a $500 catch-up for participants age 55+. HSAs replaced the more limited Medical Savings Accounts (MSAs) that had existed since 1996 in pilot form.

2006

Tax Relief and Health Care Act expands flexibility

The Tax Relief and Health Care Act of 2006 made several HSA-friendly changes: allowed one-time IRA-to-HSA transfers, increased contribution limits to the maximum out-of-pocket allowed for HDHPs (eliminating the prior limitation that contributions could not exceed the deductible), and clarified that employer HSA contributions made through cafeteria plans are not subject to FICA. These changes drove the first big wave of HSA enrollment growth from roughly 1 million accounts in 2005 to 6 million by 2008 (EBRI HSA Database).

2010-2011

ACA restricts OTC drug reimbursement

The Affordable Care Act of 2010 included a provision restricting HSA (and FSA) reimbursement for over-the-counter drugs to those with a doctor's prescription, effective 2011. The change was unpopular - it forced participants to get prescriptions for things like aspirin to use HSA dollars. The ACA also raised the penalty for non-qualified HSA withdrawals from 10% to 20%. The OTC restriction lasted nearly a decade before being reversed.

2020

CARES Act restores OTC drug reimbursement

The Coronavirus Aid, Relief, and Economic Security Act of March 2020 permanently restored HSA reimbursement for over-the-counter drugs without requiring a prescription, retroactive to January 1, 2020. The change applied to FSAs, HSAs, and HRAs. The CARES Act also added menstrual care products as qualifying medical expenses for HSA reimbursement, the first such expansion in nearly 20 years of HSA history.

2024

Largest single-year increase

The 2024 HSA contribution limit jumped from $3,850 to $4,150 for self-only coverage (a $300 increase, the largest single-year step in HSA history). The 2024 family limit jumped from $7,750 to $8,300. The increase was driven by chained CPI adjustments that exceeded typical year-over-year growth, plus the inflation surge of 2022-2023 catching up in the lagging IRS adjustment formula.

2026

Where HSA limits stand today

Revenue Procedure 2025-19 sets the 2026 HSA contribution limits at $4,400 self-only and $8,750 family. The separate age-55 catch-up is $1,000 under Internal Revenue Code Section 223(b)(3); it is statutory, not an indexed amount set by the Revenue Procedure. For 2026, an HSA-qualified HDHP must have a deductible of at least $1,700 self-only or $3,400 family, and its out-of-pocket ceiling cannot exceed $8,500 self-only or $17,000 family. HSA assets industry-wide reached approximately $137 billion in 2024 (Devenir HSA Research Report) across roughly 39 million accounts.

Things you might not know

The HSA's 2024 industry asset total ($137B) doubled in just five years. Pandemic-era HDHP enrollment growth plus stronger investment uptake (more participants treating HSAs as long-term investment vehicles rather than spending accounts) drove the asset growth from roughly $66B at end of 2019 to $137B by end of 2024 (Devenir).
You can reimburse yourself decades later. There's no time limit on HSA reimbursement: a $500 medical expense paid out-of-pocket today, with the receipt saved, can be reimbursed tax-free from your HSA in 2050 if you choose. The "shoe-box strategy" exploits this to convert the HSA into a multi-decade tax-free growth account while preserving access to the original contributions.
Payroll HSA contributions can avoid FICA, while 401(k) deferrals don't. Traditional 401(k) deferrals reduce federal income-taxable income but not FICA wages. Eligible HSA contributions made through a qualifying cafeteria-plan payroll arrangement can reduce both. In an illustrative 22% federal bracket, a $4,400 payroll HSA contribution would reduce federal income tax by about $968 and employee FICA by about $337, or $1,305 combined, before state-tax effects.
HSAs are portable; FSAs aren't. When you change jobs, HSA balances stay with you (it's your account at the bank, not the employer's). FSA balances generally don't carry over (use-it-or-lose-it, with limited exceptions). This is the core reason HSAs have grown 10x faster than FSAs over the past two decades.
Some states tax HSA contributions and growth. California and New Jersey do not fully conform to federal HSA tax treatment. Check current state rules before assuming the federal tax treatment applies to a state return.

HSA self-only contribution limit by year

The self-only HSA contribution limit since Health Savings Accounts began in 2004. Family-coverage limits run roughly double. The separate $1,000 age-55 catch-up is statutory under IRC Section 223(b)(3), not part of the annually indexed series.

Frequently Asked Questions

What is the 2026 HSA contribution limit?

Revenue Procedure 2025-19 sets the 2026 HSA contribution limit at $4,400 for self-only coverage and $8,750 for family coverage. Internal Revenue Code Section 223(b)(3), rather than the annual Revenue Procedure, provides the separate $1,000 catch-up for eligible participants age 55 or older. A qualifying 2026 High-Deductible Health Plan has a minimum deductible of $1,700 self-only / $3,400 family and a maximum out-of-pocket amount of $8,500 self-only / $17,000 family.

When did HSAs start?

HSAs were created by the Medicare Modernization Act of 2003 (signed December 8, 2003) and became effective January 1, 2004. They replaced the more limited Medical Savings Accounts that had existed since 1996 in pilot form. The original 2004 contribution limit was $2,600 self-only and $5,150 family, with a $500 catch-up at age 55+.

Why is the HSA called the 'triple tax advantage' account?

Eligible HSA contributions are deductible for federal income-tax purposes; contributions made through a qualifying cafeteria-plan payroll arrangement can also avoid FICA. Account growth and qualified medical-expense withdrawals are tax-free federally. The HSA's structure is unique to qualified medical-expense use; non-qualified withdrawals before age 65 generally trigger ordinary income tax plus a 20% additional tax.

Can I use HSA dollars for non-medical expenses after age 65?

Yes. After age 65, non-qualified HSA withdrawals are still subject to ordinary income tax (like a Traditional IRA distribution), but the 20% penalty disappears. This is why many tax-aware savers treat the HSA as a 'stealth Traditional IRA' - the contribution and growth are tax-free, and after 65 the withdrawal mechanics match a Traditional IRA. Medical-expense withdrawals remain entirely tax-free at any age.

What's the 'shoe-box strategy' for HSAs?

Pay current medical expenses out-of-pocket while keeping receipts (in a literal or figurative shoebox), and let the HSA balance grow tax-free for decades. Years or decades later, withdraw the accumulated medical-expense reimbursements all at once - tax-free, regardless of when the expense was originally incurred (no time limit on reimbursement). This converts the HSA into a long-term tax-free growth vehicle while still allowing access to the contributions tax-free at any time.

Can I contribute to an HSA if I'm on Medicare?

No. Medicare enrollment makes you ineligible to contribute to an HSA, regardless of your other coverage. This is why many people delay Medicare Part A enrollment past age 65 if they want to keep contributing to an HSA. Existing HSA balances remain usable for qualified medical expenses (including Medicare premiums after age 65), but new contributions stop. The 6-month retroactive Part A coverage rule that triggers when you claim Social Security after age 65 is a common HSA-eligibility trap.
