It’s totally worth while and anyone with predictable expenses should do it

you save the taxes AND it may lower your tax bracket! Suppose I have $2000 in medical bills. Most of my income is taxed at 25%, so it takes $2.666 of income to pay that $2000 in bills. If I put the $2000 in the FSA, it’s tax-free, so I pay $2000 of bills with $2000 in income, and I get to keep $648, minus taxes, or $499. So putting $2000 in the FSA gets me best online payday loans almost $500 more cash in my pocket. PLUS, my income is lowered by $2000, which helps keep the next tax bracket farther away. (although personally since I file Head of Household, that’s too big a range to move out of either way)
