Frequently Asked Questions
Common questions about this calculator.
Who needs to pay quarterly estimated taxes?
The IRS requires quarterly estimated payments if you expect to owe at least $1,000 in taxes for the year after subtracting withholding and credits. This typically applies to freelancers, sole proprietors, partners, and S-corp shareholders who receive self-employment income.
What is Self-Employment (SE) tax?
SE tax covers both the employer and employee portions of Social Security (12.4%) and Medicare (2.9%), totaling 15.3%. It applies to 92.35% of your net self-employment income (after expenses). You can then deduct 50% of your SE tax from your gross income before calculating federal income tax.

The 2025 quarterly estimated tax due dates are: Q1 — April 15, Q2 — June 16, Q3 — September 15, Q4 — January 15, 2026. Missing these dates may result in IRS underpayment penalties, typically 6–8% annualized.
