3 Costly S‑Corporation Mistakes

S Corps can save real money on taxes—if you dodge these common traps.

Why Small‑Business Owners Should Care

Choosing S‑Corporation status is a top strategy for cutting self‑employment tax, but many owners never see the savings—or worse, trigger IRS penalties—because of three avoidable mistakes.

1  Ignoring the Reasonable Salary Rule

The S‑Corp tax benefit works only when you pay FICA tax on wages, not on full profit. Example: $100,000 profit with a $50,000 salary can save about $7,000 in Social Security and Medicare taxes. Pay yourself the entire $100,000 as wages and you lose the break.

2  Skipping Payroll Tax Filings & Deposits

Once you set a salary, you must run actual payroll: withhold taxes, remit them, and file Forms 941, 940, W‑2, and W‑3 on time. Many owners write themselves “salary” checks without doing the filings—triggering late‑deposit penalties, interest, and possible trust‑fund recovery penalties.

3  Paying Out More Than Your Shareholder Basis

Shareholder basis = contributions + taxed profits − prior losses − prior distributions. Distribute more than that, and the excess becomes a taxable capital gain. Example: Basis $40,000, distributions $60,000 → extra $20,000 taxed as a gain. Keeping a simple basis schedule (see Form 7203) avoids unwanted surprises.
