A Health Savings Account (HSA) is a tax-advantaged savings account designed to help individuals save for medical expenses. To qualify for an HSA, you must be enrolled in a high-deductible health plan (HDHP). Contributions to the account are tax-deductible, and the funds can be used tax-free for eligible medical costs, such as doctor visits and prescription medications. HSAs offer several benefits, including the ability to roll over unused funds from year to year, making them a long-term savings option. Additionally, the money in an HSA can be invested, potentially growing over time, which can help cover future healthcare expenses.
