How to Pay Federal Estimated Taxes Online

Some individuals and business entities are required to make estimated tax payments to the IRS every quarter.

Taxpayers must generally pay at least 90 percent of their taxes throughout the year through withholding, estimated tax payments or a combination of the two. If they don’t, they may owe an estimated tax penalty.

If you want to avoid massive taxes due at the end of the year with penalties and interest, it is important to know 1.) if you need to make estimated tax payments and 2.) how much payments to make.

Are you required to pay estimated taxes?

Wage earners

Wage earners have federal taxes withheld from their paychecks. Wage earners who correctly fill out their Form W-4 generally do not need to make estimated tax payments unless they have other income outside of their employment. If you’re not sure if your withholding is enough, visit the IRS’s tax withholding estimator.

This other income includes unemployment compensation and the taxable part of Social Security benefits.

Freelancers and independent contractors

If you freelance or are working as an independent contractor, then your income taxes are not withheld. You must make your estimated tax payments throughout the year so that you end up with a large balance at tax time that you cannot pay.

How to determine estimated taxes to make?

1. The easy way – divide the prior year tax by 4

This is also known as the “safe harbor rule”. If you make estimated tax payments for this year that are at least 100% of the tax owed on your prior year return, then you will not owe an estimated tax penalty.

This method is recommended only if you expect your income to be close to what it was last year.

Here’s how to calculate your estimated tax payment using the safe harbor rule.

Bob’s 2018 Form 1040 shows $100,000 on line 15 of the return (total tax). He divides $100,000 by 4, resulting in $25,000. He must make a $25,000 estimated tax payment every quarter to avoid paying an estimated tax penalty.

2. The hard (but more accurate) way – use the IRS’ estimated tax worksheet

You’ll have to download the 1040-ES worksheet from the IRS’ website: Link.

Starting on pg 6 of the PDF, you’ll see the estimated tax worksheet. You may need a CPA to assist you.

It’s recommended that you use the estimated tax worksheet if your income will be much greater or lesser than last year.
