Health Savings Accounts with Group Health Plans
A Health Savings Account (HSA) is a tax-advantaged savings account available exclusively to individuals enrolled in an HSA-compatible High Deductible Health Plan (HDHP). HSAs offer a unique triple tax advantage: contributions go in pre-tax, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. No other savings vehicle in the US tax code offers this triple benefit.
2024 HSA contribution limits: $4,150 for self-only HDHP coverage; $8,300 for family coverage. If you're 55 or older, an additional $1,000 catch-up contribution is allowed. Both employers and employees can contribute — the total combined contribution cannot exceed the annual limit.
Employer HSA Contributions as a Benefits Tool
Employers who switch from a traditional plan to HDHP+HSA can redirect premium savings into employee HSA contributions. For example: switching from a $750/month PPO to a $550/month HDHP saves $200/employee/month. Contributing $100/month into each employee's HSA gives employees $1,200/year toward their deductible while still saving $100/month vs. the old plan. Employees see a tangible employer contribution, improving benefits satisfaction.
HSA Investment and Long-Term Growth
Unlike Flexible Spending Accounts (FSAs), HSA funds roll over year to year indefinitely — there's no "use it or lose it." Once the account balance reaches $1,000–$2,000 (varies by provider), employees can invest the balance in mutual funds. Long-term, an HSA can accumulate significant healthcare savings. After age 65, HSA funds can be withdrawn for any purpose (ordinary income tax applies, like a traditional IRA).
Setting Up HSA with Your Group Plan
When an employer offers an HDHP, employees open HSAs at a bank or HSA custodian — Fidelity, HSA Bank, Optum Bank, and HealthEquity are popular options. Employer contributions are made via payroll integration. Employees receive a debit card linked to the HSA for qualified medical expenses. The employer's broker typically helps set up payroll deduction administration.
