What Is a HDHP (High Deductible Health Plan) with HSA?
HDHPs have higher deductibles ($1,650+ for individuals in 2026) but lower premiums and qualify you to contribute to a Health Savings Account (HSA). The HSA provides a triple tax advantage: pre-tax contributions, tax-free growth, and tax-free withdrawals for medical expenses.
Best for: healthy individuals who want the lowest possible premiums, can afford to pay their deductible if needed, and want to build tax-advantaged savings for future healthcare costs.
Watch out for: HDHPs are not ideal if you have high ongoing medical costs that will consistently exhaust your deductible. Run the numbers: low premium savings may not offset high out-of-pocket costs if you use a lot of healthcare.
