When Are Taxes Due for 2019? — Tax Year Dates You Need to Know

There's more to tax filing deadlines than a single date.
  • For most taxpayers, taxes are due April 15.
  • However, this deadline changes if you need to make estimated tax payments as a self-employed taxpayer.
  • You can also request an extension so you don’t have to file taxes until October.

Tax season is full of questions concerning your wages, your claims, your filing status, etc. But even after those are answered, one burning question remains: When are taxes due?

You might not like paying taxes, but you certainly won’t like paying interest, late filing fees and late payment fees if you miss the deadline to file taxes for tax year 2018. The Internal Revenue Service has several deadlines to file taxes and pay your taxes due so it’s important you are aware of all applicable dates.

When Are Taxes Due? Monday, April 15, 2019

For most taxpayers, the main income tax return deadline for 2018 tax returns is April 15, 2019 — aka IRS Tax Day 2019. You can file any time from now until April 15 (or April 17, if you live in Maine or Massachusetts).

The deadlines differ for individuals versus businesses, and it depends in part on whether you use a calendar year or a fiscal year. If you’ve already missed a deadline, file and pay your taxes as soon as possible to stop additional interest and penalties from accruing.

Estimated Tax Payments

If you have taxable income from being self-employed or have a business, you will need to make estimated tax payments throughout the year, because you’re required to pay income taxes as you earn your income. Note that generally,  you should only expect to pay estimated tax if you think you’ll owe at least $1,000 in tax for 2019.

The following table shows the quarterly 2019 tax year dates for payment for self-employment tax and estimated taxes.

2019 Tax Deadlines for Estimated Taxes

Tax Year vs. Calendar Year

Not all taxpayers use Jan. 1 through Dec. 31 as their tax year. Some use a fiscal year, which is a 12-month period ending on the last day of any month except December, according to the IRS. In general, companies are the only ones that use a fiscal year for tax purposes, but if you are an individual and you keep your financial records on the basis of an adopted fiscal year, you can apply to use the fiscal year instead. If you want to change your tax year, and thus your tax return due date, you must apply for that via the IRS.

Most Important Tax Dates for Individuals

For individuals who use a calendar year as their tax year, here’s a quick look at important dates for your 2018 tax return, due in 2019:

Important 2019 Tax Due Dates for Individuals
Jan. 15, 2019If you are required to make estimated tax payments, your payment for the fourth quarter of tax year 2018 is due on this date. Submit with Form 1040-ES Voucher 4 or pay online.
Jan. 31, 2019If you are required to make estimated tax payments but do not make your fourth quarter payment by Jan. 15, you can avoid interest and penalties by filing your return and paying any taxes due by Jan. 31.
April 15, 2019Deadline for filing and paying your 2018 income taxes. Most individuals use Form 1040.
April 15, 2019This is also the deadline for requesting an automatic six-month extension to file your income taxes with Form 4868. However, this is only an extension for filing: You must still pay any tax due on time.
April 15, 2019The first quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.
June 15, 2019Deadline for filing for individuals living or working outside the U.S. and Puerto Rico.
June 17, 2019The second quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.
Sept. 16, 2019The third quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.
Oct. 15, 2019Income tax filing deadline for taxpayers who requested a six-month extension to file their returns. Returns are still filed with form 1040.
Jan. 15, 2020The fourth quarterly payment is due for individuals who must make estimated tax payments using Form 1040-ES.

Although you can file for a tax extension, the extension only extends your income tax deadline to file. It doesn’t change your payment due date.

Paying what you expect to owe on or before tax day avoids interest and penalties. If you estimate too little, you’ll owe interest on the unpaid portion, but you won’t be charged late-payment penalties if you pay at least 90 percent of what you owe by the standard tax deadline and you pay the remainder in full when you file your taxes by the extended tax return date.

Most Important Tax Dates for Business Owners

The following are the most important tax dates for businesses that use a calendar year as their tax year. If your business uses a fiscal year, taxes are due on the 15th day of the third or fourth month after the business’ tax year, depending on what type of business it is.

The dates for corporations are different from the dates for partnerships and S corporations because the partnership and S corporation income passes through to the owners of the business. Corporations, on the other hand, pay the taxes themselves.
