Open a Health Savings Certificate Account.
A Health Savings Account (HSA) is a special account that allows you to set aside money to help pay for future medical expenses, and deduct those contributions on your tax return. To qualify for an HSA, you must be covered by a High Deductible Health Insurance Plan (HDHP) and satisfy other eligibility requirements.
HSA funds are never taxed when used for qualified medical expenses, and all unused funds can be rolled over from year to year, even if you change jobs. You can learn more about HSAs from the federal government.
