Enter your actual P&L each quarter and we'll calculate what you owe — not just an even split of last year's bill. Compare the P&L method to safe harbor side by side and always know where you stand.

FICA is withheld from this — no SE tax owed separately
Already paid — credited against your estimated tax balance
S-Corp owners pay FICA (Social Security + Medicare) through W-2 payroll — already handled by your S-Corp. No additional SE tax is included in your quarterly estimates. Estimates here cover federal income tax and state tax only on total income (salary + distributions + other).
Sole props and single-member LLCs have no W-2, so SE tax (15.3% up to $176,100, then 2.9%) is calculated and included in your quarterly payment estimates. You get to deduct half of SE tax and take the 20% QBI deduction from taxable income.
