This document compares Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs), giving 5 reasons why HSAs are better. HSAs can be rolled over each year without penalties, are portable, can be invested like retirement accounts to grow over decades, help plan for future retirement health expenses, and allow choice of provider. In contrast, FSAs must be used each year or funds are forfeited, are owned by employers, do not earn interest or grow long-term, and expire each year. The document recommends considering HSAs for budgeting given rising healthcare costs and their unmatched savings and growth features compared to FSAs.
