Health FSA Opportunity & Savings

Estimate employer payroll-tax savings and employee tax benefit from a Health FSA program.

Created by Corry Hull, REBC®, CSFS® for Employer Benefits IQ.

1.How well-designed is your Health FSA program, including election limits, carryover or grace-period rules, and eligible expense guidance?

2026 employee salary-reduction limit: $3,400. Carryover limit: $660 (2026).

2.How high is employee participation in your Health FSA and how do you drive enrollment?

Average FSA participation is 20–30% of eligible employees. Higher participation requires active communication.

3.How thoroughly do you conduct and document nondiscrimination testing for your Health FSA?

Health FSAs must pass eligibility and benefits tests under IRC §105(h). Failure can result in taxable benefits for HCEs.

4.How clearly do you communicate the limited-purpose FSA option for employees enrolled in an HSA-qualified HDHP?

A limited-purpose FSA (dental and vision only) preserves HSA eligibility while providing pre-tax savings.

5.How effectively is your FSA administered, including claims substantiation, debit card controls, and run-out period management?

IRS requires substantiation for all FSA claims. Debit card transactions require additional documentation controls.
