What is Form 1040-ES?

IRS form and vouchers used to calculate and pay quarterly estimated taxes for income not subject to withholding.

Definition

Form 1040-ES is used by individuals to calculate and pay estimated taxes on income that is not subject to withholding, including self-employment income, investment income, and foreign income. The form includes a worksheet for estimating the required payments and vouchers for mailing payments. Payments are due quarterly: April 15, June 15, September 15, and January 15. For US expats, Form 1040-ES is critical because foreign income typically has no US withholding.
