Estimated Tax: Estimated Tax for Self-Employed
Quick answer
Self-employed taxpayers with no withholding generally pay estimated tax in four quarterly installments on Form 1040-ES, covering both income tax and self-employment tax. The IRC §6654 underpayment penalty is avoided by paying at least 90% of current-year tax or 100% of prior-year tax, rising to 110% of prior-year tax for higher-income taxpayers.
Estimated Tax for Self-Employed is tested on EA Exam Part 2 (Individual Taxpayer Issues). Primary IRS reference: IRC §6654.
