Why 90% of People Get FSA and HSA Completely Wrong — Here’s the Fix

Many Americans are navigating the confusion around Health Savings Accounts (HSAs) and Flexible Spending Accounts (FSAs), all while trying to manage rising healthcare costs. A striking number—around 90%—seem to misunderstand the fundamental benefits and rules of these tax-advantaged accounts, often leading to missed savings and mistakes.
