Health Savings Account (HSA)

What Is a Health Savings Account (HSA)?

A Health Savings Account is a tax-advantaged account that lets employees enrolled in a high-deductible health plan (HDHP) set aside money for qualified medical expenses. Unlike many workplace benefits, the account belongs to the employee, not the employer, and the balance never expires.

Contributions are typically deducted from payroll on a pre-tax basis, the same mechanism that governs other common payroll deductions.

How Does an HSA Work?

Employees who enroll in a qualifying HDHP can open an HSA and contribute up to an annual IRS limit. Employers may also contribute, and both sources count toward the same yearly cap.

Unused funds roll over indefinitely, which distinguishes an HSA from FSAs that typically require use-it-or-lose-it spending, a distinction worth building directly into pretax insurance communications during open enrollment.

What Are the 2026 HSA Contribution Limits?

The IRS raises HSA and HDHP thresholds most years to keep pace with healthcare costs.

According to SHRM, 60% of employers now offer an HSA and 62% of those contribute directly to employee accounts, with average family contributions running $1,633 a year.

How Is an HSA Different From an FSA?

The two accounts are easy to confuse, but the rules diverge in ways that matter for plan design. Indeed highlights that HSAs allow annual rollover and higher contribution limits, while FSA funds are generally forfeited if unused by year-end.

Communicating these mechanics clearly matters because open enrollment is often where employees make the wrong call by default. AI benefits enrollment software can help surface which account actually fits an employee's expected medical spending instead of leaving the decision to guesswork.

What Are the Tax Advantages of an HSA?

An HSA offers what's often called a triple tax advantage: contributions reduce taxable income, growth inside the account isn't taxed, and withdrawals for qualified expenses are tax-free. Forbes notes this trifecta is one of the more overlooked benefits available through an employer-sponsored plan.

That tax efficiency matters more as healthcare costs keep climbing. The World Economic Forum has noted that health spending now consumes roughly 10% of global GDP, a trend that makes tax-advantaged savings tools like an HSA increasingly valuable to household budgets.

Why Should Employers Offer an HSA?

Beyond the tax benefits to employees, HSAs are relatively simple to administer compared to other benefit structures. Pairing HSA administration with an ASO benefits arrangement lets a third-party provider handle enrollment, contribution tracking, and compliance reporting.

For growing organizations, tracking HSA and FSA elections accurately inside a unified HRMS platform prevents the payroll errors that crop up when benefits data and payroll systems drift out of sync.

Clearly showing employees the real dollar value of an HSA, including any employer contribution, through employee benefits management software helps convert a line item on a benefits menu into a benefit employees actually understand and use.

Frequently Asked Questions

Q: Do I need a high-deductible health plan to open an HSA?

A: Yes. Enrollment in a qualifying HDHP is required to open and contribute to an HSA.

Q: Does HSA money expire at the end of the year?

A: No. Unlike most FSAs, HSA balances roll over indefinitely and remain yours even if you change jobs or health plans.

Q: What is the 2026 HSA contribution limit?

A: For 2026, the limit is $4,400 for self-only coverage and $8,750 for family coverage, both up slightly from 2025.

Q: Can both an employer and an employee contribute to the same HSA?

A: Yes. Both contributions count toward the same annual IRS limit, so employer contributions reduce how much an employee can add on their own.

Q: Can I use HSA funds for non-medical expenses?

A: You can, but withdrawals for non-qualified expenses before age 65 are subject to income tax plus a 20% penalty. After 65, the penalty no longer applies, though income tax still does.
