A type of savings account that allows you to set aside money on a pre-tax basis to pay for qualified medical expenses if you have a “high deductible” health insurance plan.
Combining a High Deductible Health Plan with a Health Savings Account (HSA) allows you to pay for certain medical expenses, like your deductible and copayments, with untaxed dollars. High-deductible plans usually have lower monthly premiums than plans with lower deductibles.
Unlike a Flexible Spending Account (FSA), HSA funds roll over year to year if you don't spend them. You can take the funds with you if you change jobs or leave the work force. Your HSA may also earn interest.
You can start an HSA through your own bank or other financial institution.
