When a Florida employee pays $300 a month toward health premiums, whether that comes out before or after tax decides how much it really costs. Pre-tax, that $3,600 a year escapes federal income tax and the employee's 7.65% FICA — and the employer skips its matching 7.65% too. After-tax, everyone overpays. The mechanism that makes premiums pre-tax is a Section 125 cafeteria plan; without it, the deduction is legally after-tax no matter what your payroll software labels it.
For 2026 this is one of the simplest, highest-return tax moves a Florida employer and employee can make together. This guide explains exactly how the savings work, the Florida-specific angle, and the one trade-off worth knowing.

The Assumption That Quietly Wastes Money
Many small Florida employers deduct premiums from paychecks and assume that makes them pre-tax automatically. It does not. To deduct premiums pre-tax, you must have a written Section 125 plan document in place. Without it, the IRS treats the deduction as after-tax: the employee is taxed on the premium dollars and the employer pays FICA on them needlessly. The cost of a Section 125 plan document is small, and it pays for itself in the first year of payroll-tax savings. If you offer any payroll-deducted coverage and do not have a cafeteria plan, that is the first thing to fix. See our Section 125 guide for the setup details.
The Three Layers of Savings
| Tax | Saved on Pre-Tax Premiums? |
|---|---|
| Federal income tax (employee) | Yes |
| FICA — Social Security + Medicare (employee 7.65%) | Yes |
| FICA match (employer 7.65%) | Yes |
| Florida state income tax | N/A — Florida has none |
The employer match savings are the part owners overlook. On a $3,600 annual premium run pre-tax, the employer saves about $275 per employee in FICA. Across a 25-person workforce, that is roughly $6,900 a year in payroll tax — recurring, with no downside.
A Worked 2026 Example
Take a Tampa employee in the 22% federal bracket paying $400/month ($4,800/year) toward family premiums. Pre-tax, they avoid roughly $1,056 in federal income tax and about $367 in FICA — saving close to $1,423 a year compared with paying after-tax. Their employer saves another ~$367 in matching FICA. Same coverage, same premium, materially lower cost on both sides — purely because the deduction is structured pre-tax through a cafeteria plan.
The Florida Angle — and the Trade-Off
In an income-tax state, pre-tax premiums also save state income tax, so the headline savings look bigger there. In Florida, the savings come from federal income tax and FICA only — but the FICA piece, which employers care about most, is identical everywhere, and Florida employers skip the state-payroll-tax bookkeeping entirely. There is no Florida wage base to reconcile and no state-conformity question, so the administration is genuinely simpler here.
The one trade-off applies to lower earners. Because pre-tax premiums reduce the wages on which Social Security is calculated, an employee earning below the 2026 Social Security wage base of $184,500 slightly reduces the earnings that count toward their future Social Security benefit. For most workers the immediate tax savings far outweigh the tiny long-run benefit reduction, but it is worth understanding. Employees earning above $184,500 see no Social Security effect at all on the portion above the base, since those wages were not subject to the 12.4% Social Security tax anyway.
Through a Section 125 plan, employees can pay group medical, dental, and vision premiums pre-tax, fund a health FSA (up to $3,400 for 2026), a dependent care FSA (up to $5,000), and HSA contributions (up to $4,400 self-only / $8,750 family for 2026). HSA contributions made this way also avoid FICA — the only method that achieves it.
Common Mistakes to Avoid
- No Section 125 plan document. Without it, "pre-tax" deductions are really after-tax.
- Running HSA contributions outside the cafeteria plan. You lose the FICA savings; route them through Section 125.
- Forgetting nondiscrimination testing. A plan that favors highly compensated employees can lose pre-tax status for them.
- Letting employees change elections at will. Elections are locked for the year absent a qualifying life event.
- Overlooking the employer savings. The 7.65% match reduction often justifies the plan by itself.
Capture the Savings This Year
If your Florida business deducts premiums from paychecks, confirm you have a Section 125 plan so those deductions are truly pre-tax — and route HSA contributions through it too. A licensed Florida producer can help you put the structure in place and pick coverage that pairs well with pre-tax funding. Get free help, or explore plan options on Get Florida Coverage.
How It Shows Up on the Paycheck and W-2
The effect of pre-tax premiums is visible right on the pay stub and year-end W-2. On each paycheck, the premium is subtracted before federal income tax and FICA are computed, so the employee's taxable wages and tax withholding are both lower than the gross. On the W-2, those pre-tax premiums reduce the wages reported in Box 1 (federal taxable wages) and in Boxes 3 and 5 (Social Security and Medicare wages) — which is exactly why both income tax and FICA are saved. Separately, the total cost of employer-sponsored coverage is reported for information only in Box 12 with code DD; that figure is not taxable and is purely a transparency disclosure. After-tax premiums, by contrast, never reduce any of those boxes, which is the tell-tale sign a business lacks a proper Section 125 plan. If your employees' Box 1 wages do not reflect their premium contributions, the deductions are not actually pre-tax and the savings are being lost.
