How It Works
HSA and FSA accounts let you pay for dental expenses with pre-tax dollars, effectively giving you a discount equal to your marginal tax rate. An HSA is available with high-deductible health plans and funds roll over indefinitely. An FSA is use-it-or-lose-it but available with any employer plan.
The Formula
Tax Savings = min(Dental Expenses, Account Limit) x (Federal % + State % + FICA %)
Effective Cost = Expenses - Tax Savings
Effective Discount = Total Tax Rate
Effective Cost = Expenses - Tax Savings
Effective Discount = Total Tax Rate
Variables
- HSA Limit — $4,150 individual / $8,300 family (2025)
- FSA Limit — $3,200 per employee (2025)
- FICA — 7.65% (6.2% Social Security + 1.45% Medicare)
Example
$2,000 dental expenses in the 24% bracket with 5% state tax and 7.65% FICA = 36.65% savings = $733 in tax savings. Effective cost: $1,267.
Tips
- HSA is strictly better than FSA — funds roll over and grow tax-free
- FSA "use-it-or-lose-it" means you should estimate dental costs carefully
- Time elective dental work to max out your FSA before year-end
- HSA funds can invest and grow — treat it as a retirement account if you can afford to pay cash now
- Cosmetic procedures (whitening, veneers) are NOT eligible for HSA/FSA
