How to Pay Quarterly Taxes

Paying taxes four times a year sounds onerous, but it actually eases the burden of year end taxes. If that isn't enough of an incentive, the penalties for not paying quarterly taxes on time should convince you to get it right.

Estimating your quarterly taxes is a recurring exercise that some would compare to a doctor's examination. Paying taxes is never fun, but the exercise also provides you a chance to check on the health of your business. The IRS considers taxes to be paid as you go and requires everyone to pay towards their tax liability throughout the year as income is earned. Employees do this through automatic withholding which the employer pays to the IRS.

Businesses and the self-employed are not subject to withholding and are instead required to estimate their tax liability and make quarterly payments toward it. Upon filing an annual return, any amount still owed is paid, and any overpayment is refunded.

Do I Need to Pay Estimated Quarterly Taxes?

You need to pay estimated quarterly taxes if you meet both of the following two conditions:

  • You expect to owe more than $1,000 at year-end ($500 for corporations), even after accounting for any withholding and refundable credits
  • Your withholding and refundable credits are less than the smaller of 90% of your current year tax liability, or 100% of your previous year tax liability (110% if your Adjusted Gross Income exceeded $150,000, or $75,000 for married filing jointly)

This means if you expect to owe less than $1,000 after withholding and credits, you can stop right here. If you expect to owe more, but your withholding and refundable credits were equal to 90% of your current tax liability or 100% of your previous year's tax liability, you're also exempt.

If you owe more than $1,000 and your withholding and credits do not equal the necessary amounts, you need to pay estimated quarterly taxes.

You also don't need to pay quarterly taxes if you had no tax liability for the previous year, you were a U.S. citizen for the whole year, and your prior tax period covered twelve months.

When Do I Pay Estimated Quarterly Taxes?

Estimated payments are due according to the following schedule:

  • April 15
  • June 15
  • September 15
  • December 15 for corporations and January 15 of the following year for individuals

If any due date falls out on a holiday or weekend, the deadline is pushed off to the next business day.

You can choose to pay at more frequent intervals if you find that more convenient, as long as you have paid the full amount due by each quarterly due date.

Bear in mind that even if you have paid in full by year-end or you are owed a refund, you will still incur a late penalty and possibly interest if any individual payment was late or too small.

How Do I File Quarterly Taxes?

The first thing you need to do is estimate your current expected tax liability. This number divided by four equals your quarterly payment amount.

Of course, coming up with your tax liability can be a complex calculation, particularly if you don't earn income evenly throughout the year, or if your business has changed significantly from last year.

Paying 100% of your previous year's tax liability is the “safe harbor" method if you are unsure about your current year's income. The IRS has a guide included with Form 1040-ES that can help you calculate your payment amount, or an experienced accountant can help you arrive at your payment amount.

Once you have calculated your payment amount you can pay online through the Electronic Federal Tax Payment System or directly on the IRS website. You can also send in a check or money order along with the vouchers included with Form 1040-ES.

What if I Don't Pay Quarterly Taxes?

Paying late, underpaying, or skipping a payment is penny-wise and pound foolish. You will need to pay the IRS eventually and it will cost you more later on. The IRS uses a complicated formula to calculate penalties and is usually kind enough to calculate them for you.

Typically, any missed payment or short payment is assessed as a penalty that begins at .5% of the amount due, but the rate increases over time based on how long the bill was outstanding.

Since interest begins to accrue only after the annual return due date, taking care of any penalties immediately serves to avoid interest and to keep the penalty rate down. Form 2210 can help calculate your penalty and possibly lower or eliminate it if your short payment was due to uneven income.

As burdensome as quarterly taxes are, they merely expedite the inevitable while eliminating the chances of a large, unexpected bill at year end. With this perspective, it certainly makes sense to get it right from the start.
