Certain types of workers must make estimated federal income tax payments if they expect to owe $1,000 in taxes at year's end. Small business owners and those earning self-employment income often have to make these payments. If you have to make estimated payments, you do so four times a year using IRS Form 1040-ES.
Payment Due Dates
The quarterly estimated tax payments are typically due April 15, June 15, September 15 and January 15 of the following year. You need to make these payments on time to avoid late payment penalties from the IRS. If the 15th day of any of these months falls on a Saturday, Sunday or holiday, you can make payment the following business day. If you mail a check with the form, the postmark date is considered your date of payment.
