IRC §223
Health Savings Account (HSA)
HSAs provide a triple tax advantage: tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. With a high-deductible health plan, HSAs are one of the most tax-efficient savings vehicles available.
Who this may apply to
- Enrolled in a qualifying high-deductible health plan (HDHP)
- Not enrolled in Medicare
- Not claimed as a dependent
Strategy connections
Works well with
- Solo 401(k) / SEP-IRA Optimization: Can complement retirement saving when HSA eligibility is independently met.
- Backdoor Roth / Mega Backdoor Roth: Provides a separate tax-advantaged savings channel.
What could block this
- No qualifying high-deductible health plan coverage
- Disqualifying other health coverage
- Medicare enrollment
- Eligible to be claimed as another person’s dependent
Important considerations
- You cannot contribute to an HSA if you’re enrolled in Medicare, covered by a spouse’s non-HDHP plan, or claimed as a dependent
- Withdrawals for non-medical expenses before age 65 are subject to income tax PLUS a 20% penalty
- Keep receipts permanently — there is no statute of limitations on HSA reimbursements
- California and New Jersey do not recognize HSA tax benefits at the state level. Contributions are not deductible for CA or NJ income tax purposes, and HSA earnings are subject to state tax. The federal tax savings remain fully intact — our estimates for CA/NJ residents exclude the state component accordingly.

Timing
Contributions can generally be made through the tax-return due date, without extensions. Eligibility is normally determined month by month; the last-month rule may permit a full-year contribution but carries a testing period.
