How To Use The FSA Tax Savings Calculator
Step 1: Choose FSA account type
Select health care FSA, limited purpose FSA, or dependent care FSA so the calculator can apply the right 2026 limit.
Step 2: Enter your planned election
Add the employee payroll election, employer FSA contribution, and estimated eligible expenses for the plan year.
Step 3: Add dependent care limits if needed
For dependent care FSA mode, enter filing status and the lower earned income amount because those can limit the exclusion.
Step 4: Set tax rates and pay periods
Use federal, state, FICA, and pay-period inputs to estimate tax savings and per-paycheck reduction.
Step 5: Review use-or-lose risk
Compare expected eligible expenses with available FSA funds, carryover protection, forfeiture risk, and the recommended election.
How This Calculator Works
The calculator applies the 2026 health FSA salary-reduction limit of $3,400 for health care and limited purpose FSA modes. If carryover is allowed, it protects up to the 2026 $680 carryover maximum from the modeled unused balance.
For dependent care FSA mode, it applies the 2026 dependent care assistance exclusion limit of $7,500, or $3,750 for married filing separately. It also lets you cap the modeled limit by lower earned income because dependent care benefits are tied to earned income rules.
The tax savings estimate multiplies the allowed employee election by federal and state marginal tax rates, then adds employee FICA savings. The result separates tax savings, per-paycheck reduction, reimbursed expenses, carryover protection, forfeiture risk, and net estimated value.
FSA Tax Savings Planning: Health FSA, Limited Purpose FSA, And Dependent Care FSA
FSA savings come from payroll exclusion
A flexible spending arrangement lets an employee set aside wages before tax for qualifying expenses under an employer plan. That can reduce federal taxable wages, many state taxable wages, Social Security wages, and Medicare wages. The practical savings depend on your marginal tax rates and whether your state follows the federal treatment.
The main risk is over-electing. Unlike an HSA, a health FSA is employer-owned and subject to plan rules. If expenses are lower than expected and no carryover or grace period saves the balance, unused money can be forfeited.
2026 FSA limits used by this calculator
| FSA item | 2026 amount | Applies to | Planning note |
|---|---|---|---|
| Health FSA salary reduction | $3,400 | Health care and limited purpose FSA | Employee payroll election limit |
| Health FSA carryover | $680 | Health care and limited purpose FSA | Only when employer plan permits carryover |

| Dependent care FSA MFS limit | $3,750 | Married filing separately | Coordinate carefully with W-2 box 10 |
Limited purpose FSA vs health FSA
A general-purpose health FSA can make someone ineligible to contribute to an HSA. A limited purpose FSA is often used by HSA participants because it is usually limited to dental, vision, and sometimes post-deductible medical expenses. Your employer plan controls the exact definitions, so check the plan before electing.
Coordinate dependent care FSA with Form 2441
Dependent care FSA benefits can be valuable, but they reduce expenses available for the child and dependent care credit. Use this calculator for payroll-tax savings, then compare the result with the Child and Dependent Care Credit Calculator. If you are comparing FSA and HSA strategies, use the HSA Tax Savings Calculator.
