An S-Corp reasonable salary is the wage the IRS expects an owner-employee to pay themselves for the work they perform before taking profit as a distribution. Wages carry Social Security and Medicare tax; distributions do not — which is why the IRS scrutinizes the split. There is no legal percentage: the '60/40 rule' is a myth, and IRS Fact Sheet 2008-25 treats reasonable compensation as a facts-and-circumstances question built from nine factors, nearly all pointing to the value of the services performed. For tax year 2026 the Social Security wage base is $184,500, so each dollar of salary below it carries the full 15.3% combined payroll tax. A defensible number is best built with the cost approach — pricing each role you fill at market hourly rates for the hours worked — and documented in a short contemporaneous file (role description, comparable pay data, the calculation, the date). The cautionary case is David E. Watson, P.C. v. United States (8th Cir. 2012): a CPA paid himself $24,000 while taking about $200,000 in distributions, and the courts reset his reasonable salary to $91,044 with back FICA and penalties. Paying too little also backfires beyond audit risk — it caps Solo 401(k)/SEP-IRA employer contributions, can shrink the Section 199A QBI deduction for higher earners, and lowers future Social Security benefits. Florida's lack of a state income tax makes the entire decision federal.
