How it works

The 7.65% mechanic, in plain English

FICA is the employer's required match on Social Security and Medicare. Pre-tax benefit accounts shrink the wages it applies to.

Step 1

Employee elects pre-tax

Employees fund HSAs, FSAs, LPFSAs, Dependent Care, or Commuter accounts from gross pay.

Step 2

Taxable wages drop

Those contributions are excluded from FICA wages — for both the employee and the employer.

Step 3

Employer skips the 7.65% match

Every pre-tax dollar saves 6.2¢ Social Security + 1.45¢ Medicare. It compounds fast across thousands of employees.

Across 30,000 employees electing pre-tax benefits, that's millions in savings dropped to the employer's bottom line.
