Payroll Taxes Explained: An Employer's Guide for 2026

Most owners meet payroll tax the same way: the first payroll runs, the bank balance drops by more than the paychecks, and a few weeks later there is another debit labeled "IRS USATAXPYMT" for an amount nobody budgeted. Payroll software hides the mechanics well enough that you can run payroll for years without knowing why the numbers and dates fall where they do.

That works until a missed deposit, a Florida rate notice you did not understand, or a cash crunch where payroll tax looks like the easiest bill to defer. Here is what an employer actually pays, when it is due, and why the IRS treats this debt unlike any other.

Three buckets: withheld, matched and employer-only

Every payroll splits into three kinds of tax. The first is money you withhold from the employee's own wages and forward to the government: federal income tax plus the employee's share of Social Security and Medicare. It was never your money. The second is your matching share of Social Security and Medicare, a real cost on top of gross wages. The third is employer-only unemployment tax, federal and state.

Social Security and Medicare together are FICA, and the 2026 figures come from IRS Publication 15: 6.2% each side on the first $184,500 of wages, 1.45% each side with no cap. Income tax withholding is whatever the employee's W-4 produces; your job is to calculate it correctly and send it in. For an employee under the wage base, your matching cost is 7.65% of gross, the floor of what an employee costs beyond salary.

The employer-only taxes: FUTA and Florida reemployment tax

Federal unemployment tax (FUTA) is nominally 6.0% of the first $7,000 paid to each employee, but employers who pay their state unemployment tax on time get a credit of up to 5.4%, leaving 0.6%, or $42 per employee per year. The full credit depends on your state not owing the federal unemployment trust fund; for 2025 only California and the U.S. Virgin Islands lost part of it, so Florida employers pay the full-credit 0.6%.

Florida's version is called reemployment tax, and it surprises people who moved here for "no state income tax." Per the Florida Department of Revenue, new employers pay 2.7% on the first $7,000 of each employee's wages, a maximum of $189 per employee per year, until they have reported for 10 quarters. After that the state assigns an experience rate between 0.1% ($7 per employee) and 5.4% ($378) for 2026, driven by the benefits former employees have drawn against your account. A business that rarely lays anyone off drifts toward the minimum; one with seasonal layoffs pays the maximum. You become liable once you pay $1,500 in wages in a quarter or have an employee in 20 different weeks of a year, register on Form DR-1, and file Form RT-6 quarterly.

Deposits and filings: when everything is due

Deposit schedules: monthly, semiweekly and the $100,000 rule

The 941 taxes (withheld income tax plus both halves of FICA) are not paid with the quarterly return. They are deposited through EFTPS on a schedule set each year from a lookback period: the four quarters from July 1 two years back through June 30 of last year. If you reported $50,000 or less in that window you are a monthly depositor, and each month's taxes are due by the 15th of the following month. Above $50,000 you are semiweekly: taxes on Wednesday through Friday paydays are due the following Wednesday, and taxes on Saturday through Tuesday paydays the following Friday. New employers start monthly. The rules are in IRS Topic 757.

Two overrides matter. If you accumulate $100,000 or more of liability on any day, that amount is due the next business day regardless of schedule, and you become a semiweekly depositor for the rest of the year and all of next; a year-end bonus run at a 40-person company can trigger this. If your liability for the quarter is under $2,500, you can pay with the Form 941 instead. FUTA runs on its own track: deposit by the end of the month after any quarter in which cumulative FUTA liability exceeds $500.

Late deposits are penalized at 2% if 1 to 5 days late, 5% at 6 to 15 days, 10% beyond 15 days, and 15% if still unpaid 10 days after the first IRS notice, applied to the whole deposit: a $30,000 deposit sent a week late costs $1,500.

The forms and when they are due

A few notes. The IRS may notify very small employers to file an annual Form 944 instead; do not switch on your own. The W-2 totals must reconcile to the four 941s for the year, or IRS and SSA letters follow months later. Florida requires employers with 10 or more employees in any quarter to file and pay RT-6 online. If you file 10 or more W-2s and 1099s combined, all must be e-filed; our 1099-NEC filing guide covers that count.

Worked example: a $10,000 payroll

Take a Tampa dental office in its first year with four employees and a biweekly payroll of $10,000 gross, early in the year when everyone is below the $7,000 unemployment wage base. Assume the four W-4s together produce $900 of federal income tax withholding; that figure is the only assumption here.

From the employees' paychecks: Social Security $620 (6.2%), Medicare $145 (1.45%), federal income tax $900. Net pay to the four employees: $8,335. From the employer: Social Security $620, Medicare $145, FUTA $60 (0.6%), Florida reemployment tax $270 (2.7%). The employer's tax cost above gross wages is $1,095, or 10.95%, and total cash leaving the business for this one payroll is $11,095.

Where the money goes: the 941 deposit is $620 + $145 + $900 + $620 + $145 = $2,430, due by the 15th of next month because a first-year employer is a monthly depositor. Only $765 of that is the practice's own tax; $1,665 is employee money held in trust. The $270 of Florida tax goes with the RT-6 at quarter-end, and the $60 of FUTA accumulates until the balance passes $500. Once each employee has earned $7,000, about ten weeks in for a $35,000-a-year employee, both unemployment taxes stop for the year and the employer cost drops to 7.65%.

The trust fund recovery penalty: the one bill you never skip

Of the $2,430 deposit above, $1,665 was withheld from employees. The IRS calls that trust fund money and treats a business that spends it as having taken it from the employees. Under the Trust Fund Recovery Penalty, the IRS can assess 100% of the unpaid withheld income tax and employee FICA personally against any "responsible person" who willfully failed to pay it: owners, officers, a bookkeeper with signature authority, anyone who decided which bills got paid. The LLC or corporate shield does not apply, and "willful" only means you knew the tax was owed and paid something else.

This is why our advice on cash crunches is blunt: negotiate with the landlord, stretch vendors, but never fund the business with payroll tax. Owners tell themselves they will catch up next quarter; the penalties stack, and the debt follows the owner personally after the business is gone. If you are already behind, get current on new deposits first, then deal with the old balance.

Payroll provider or PEO?

A payroll provider (Gusto, ADP Run, QuickBooks Payroll and the like) calculates pay, makes the deposits, files the 941, 940, RT-6 and W-2s, and charges a base fee plus a per-employee fee. You remain the employer and the taxes are filed under your EIN. For most businesses under 25 employees this is the right tool.

A professional employer organization (PEO) goes further through co-employment: it becomes the employer of record for tax and benefits purposes, files payroll taxes under its own account, and pools your employees with thousands of others to buy health insurance and workers' compensation, usually for a percentage of payroll. In our practice a PEO earns its cost at 15 or more employees, or when you want group health benefits, carry a high workers' compensation class code, or have people in several states. Under 10 employees it usually costs more than the problems it solves.

What usually goes wrong

Three failures account for most of the payroll notices we see. A Florida rate notice arrives in December and never gets entered, so the next year runs at the wrong rate. A bonus or final paycheck is cut outside the payroll system, so nothing is withheld or deposited and the W-2 is wrong. And an owner in a tight quarter pays vendors first and the IRS second, the trust fund problem in slow motion. Less dramatic but common: an S corporation owner's health insurance left off the W-2, and a payroll vendor trusted so completely that nobody logs into EFTPS to confirm the deposits landed. The employer, not the vendor, answers for a missed one.

When to get help

Payroll tax is not hard to understand; it is unforgiving of small, repeated errors. The moment to get help is before the first hire, when the pay frequency, the Florida registration and the deposit schedule are set up once and correctly, and the moment any IRS or Florida DOR notice about payroll shows up, because those balances are cheapest to resolve early. If you are about to make your first hire, our first employee checklist walks through the registrations in order, and if you own an S corporation, your own reasonable salary runs through this same system.

Our payroll, W-2 and 1099 support service runs payroll, monitors deposits against your EFTPS account, reconciles the 941s to the W-2s every January, and handles the Florida side including rate notices. For a review of how your payroll taxes are being handled today, request a 20-minute fit call.
