Companies have figured out that the automatic nudges that fill up 401(k)s can also jump-start health savings accounts. HSAs come with a rare triple tax benefit: pretax contributions, tax-free growth, and tax-free withdrawals for eligible medical bills. That is a hard combo to beat for long term health costs.
"We've seen a lot of success with automatic features in retirement plans," said Hattie Greenan, who leads research and communications at the Plan Sponsor Council of America. "And employers are looking at how they can adopt that with other benefits." She added, "I think there's a recognition that health care is expensive, and supporting employees with that is essential."
Auto-enrollment is already standard practice in many 401(k)s. PSCA data shows about 64% of employers auto-enrolled workers in 2025, and a federal law known as Secure 2.0, passed in 2022, requires most newly formed 401(k) plans to start auto-enrolling workers beginning last year.
The logic is simple: remove the opt-in friction and more people participate. In 2025, nearly 46% of employers set up HSAs by default for employees selecting a high-deductible health plan, up from 32% in 2019.
Unlike retirement plans that often pull 3% or 6% from each paycheck by default, automatic paycheck deductions are uncommon with HSAs. Instead, companies that auto-enroll usually put starter money into the account. In 2025, about 77% of employers made some HSA contribution for employees, according to PSCA.

"If you rely on individuals to open their own accounts, it's much more difficult" to boost participation, said Ann Brisk, who serves as HSA Bank's senior managing director for strategy and innovation. Employers typically place their contributions in the HSA's cash-like side rather than directly into investments. Workers can generally move money into investments once they pass the minimum balance set by their HSA provider.
Employers that chip in do it at different levels. PSCA found that among contributing employers, 32% put in between $500 and $1,000 per worker, 29% paid $1,350 or more, while 22% contributed $500 or less.
Some firms are also testing a familiar 401(k)-style feature: a match that kicks in only if the employee contributes. Roughly 10% of employers that make HSA contributions match worker deposits, and another 7.5% are weighing the idea, PSCA found. "It's very similar to a 401(k)," Brisk said. "We think it is very easy for people to understand, and encourages people to put money in their own account."
For 2026, total HSA contributions from workers and employers cannot exceed $4,400 for self-only coverage or $8,750 for family coverage.
The shift to auto-enrolled HSAs is happening alongside broader adoption of high-deductible health plans, which frequently carry cheaper premiums than standard copay plans. Among employers offering health benefits, 31% in 2025 made available a high-deductible option paired with an HSA; that figure was 4% in 2005, KFF reports. For 2026, to qualify as a high-deductible plan under IRS rules, the deductible must be no less than $1,700 for single coverage and $3,400 for family coverage.
For your wallet, the takeaway is straightforward: more employers are opening HSAs for you, seeding them with funds, and in some cases matching your contributions. If your balance clears your provider's investment threshold, those tax perks can compound over time. How much that matters will come down to your plan choice, your employer's contribution policy, and your own health spending in a given year.
