What Are Estimated Tax Payments

Who must pay estimated tax

Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed.

Corporations generally have to make estimated tax payments if they expect to owe tax of $500 or more when their return is filed.

How to figure estimated tax

Individuals, including sole proprietors, partners, and S corporation shareholders, generally use Form 1040-ES, to figure estimated tax. Nonresident aliens use Form 1040-ES(NR) to figure estimated tax.

To figure your estimated tax, you must figure your expected adjusted gross income, taxable income, taxes, deductions, and credits for the year.

When figuring your estimated tax for the current year, it may be helpful to use your income, deductions, and credits for the prior year as a starting point. Use your prior year’s federal tax return as a guide. You can use the worksheet in Form 1040-ES to figure your estimated tax. 

When to pay estimated taxes

For estimated tax purposes, the year is divided into four payment periods. Each period has a specific payment due date. If you don’t pay enough tax by the due date of each of the payment periods, you may be charged a penalty even if you are due a refund when you file your income tax return.

Estimated tax payments are due as follows:

• January 1 to March 31 – April 15
• April 1 to May 31 – June 15
• June 1 to August 31 – September 15
• September 1 to December 31 – January 15 of the following year
