Hiring your first employee turns you into a tax collector for the government. From each paycheck you withhold federal income tax (per the employee's Form W-4) plus their 6.2% Social Security (on the first $184,500 of wages for 2026) and 1.45% Medicare (no wage cap), and you pay a matching 6.2% and 1.45% yourself, along with federal unemployment tax (FUTA, 6.0% on the first $7,000 of wages, a net 0.6% after the state credit) and Florida reemployment tax (2.7% new-employer rate on the first $7,000). On a $50,000 hire, the employer's own payroll tax runs about $4,056, roughly 8% on top of the wage. You report on Form 941 each quarter (due April 30, July 31, October 31, January 31) and Form 940 once a year, and you deposit the money electronically through EFTPS on a schedule, usually monthly by the 15th, with a next-business-day rule once you accumulate $100,000 on any single day. The most important concept is the trust-fund distinction: the income tax and employee FICA you withhold were never your money, and spending them instead of remitting them triggers the Trust Fund Recovery Penalty, 100% of the unpaid trust-fund tax assessed personally against a responsible person under IRC 6672, piercing the corporation or LLC. Before the first paycheck you need an EIN (Form SS-4), a W-4 and I-9 from the employee, Florida reemployment-tax registration, and new-hire reporting. Because Florida has no state income tax, there is nothing to withhold at the state level, so the state side is lighter than in most states, though reemployment tax on Form RT-6 still applies.
