Quarterly Tax Estimates Guide for Self-Employed

Calculating Estimates

Base your estimates on prior year income or projected earnings for the current year.

Payment Deadlines

Payments are due April 15, June 15, September 15, and January 15 each year.

Avoiding Penalties

Pay at least 90% of your current year tax or 100% of last year's tax (whichever is smaller) to avoid penalties.
