How To Make Estimated Tax Payments


A while back we wrote a post on just how the mechanics of income taxes worked with regards to you receiving a refund or having to pay Uncle Sam.  In the end it boils down to how much you had withheld from your paycheck versus the amount of tax you owe at your income level.  But what if you work for yourself (i.e. self employed) and no one is “withholding” anything from your check?  Then this post will clue you in on how you make your payments and keep Uncle Sam happy.

What is estimated tax?

Estimated tax is how you pay your taxes when you have income that isn’t subject to withholding.  Just think of it as what your employer does for you (i.e. withholds taxes from your check) when you don’t have an employer  so to speak.

Who has to pay it?

If you are filing as a sole proprietor (Schedule C), or receive income as a partner, S corporation shareholder, and/or a self-employed individual, you generally have to make estimated tax payments.  Fortunately, you only have to make payments if you expect to owe tax of $1,000 or more when you file your return.

If you are filing as a corporation you generally have to make estimated tax payments if you expect it to owe tax of $500 or more when you file its return.

When do you have to pay it?

For estimated tax purposes, the year is divided into four payment periods. Each period has a specific payment due date. If you do not 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.

For the period:              Due date:

Jan. 11 – March 31           April 15

April 1 – May 31                June 15

June 1 – August 31          September 15

Sept. 1 – Dec. 31               January 15  of the following year

How do you pay it?

To figure your estimated tax, you must figure your expected adjusted gross income, taxable income, taxes, deductions, and credits for the year.  The worksheet in Form 1040-ES will help you figure the amount.  You can then make your payment(s) using the voucher contained within or electronically via the EFTPS system.

What happens if you don’t pay it?

If you didn’t pay enough tax throughout the year (either through withholding or estimated tax payments),  you may have to pay a penalty for underpayment of estimated tax.  You can avoid this penalty if you owe less than $1,000 in tax after subtracting withholdings and credits, or if you pay at least 90% of the tax for the current year, or 100% of the tax shown on the return for the prior year, whichever is smaller.
