Already withheld and paid — credited against your estimated tax balance
S-Corp net profit flows to your personal return via K-1 — you're taxed on it whether or not you take distributions. That profit is captured in the quarterly P&L below. FICA on your W-2 salary is handled by payroll and not re-calculated here. Only enter the federal income tax already withheld from your S-Corp paycheck above.
Sole props and single-member LLCs have no W-2 — SE tax (15.3% on the first $176,100, 2.9% above) is calculated here and included in your quarterly payment estimates. You also get to deduct half of SE tax and 20% QBI deduction from taxable income.
