An HSA is a special bank account for your eligible healthcare costs. You can put money into your HSA through pre-tax payroll deduction, deposits or transfers. As the amount grows over time, you can continue to save it or spend it on eligible expenses. The money in the HSA belongs to you and is yours to keep, even if you switch jobs. The funds roll over from year to year and can earn interest. You can only contribute to an HSA if you are enrolled in a high-deductible health plan, like the Albertsons Companies HSA Plan or Kaiser CA HSA Plan.
