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 2017. The Internal Revenue Service has several deadlines to file taxes and pay your taxes due.
The main income tax return deadline for 2017 tax returns is April 17, 2018. 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 self-employment or if you are 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. Employees generally meet the pay-as-you-go requirements through income tax withholding from their paychecks.

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 to the IRS using Form 1128.
Here’s a quick look at the main tax dates for individuals, corporations, partnerships and S corporations from 2015 through 2021:
Most Important Tax Dates for Individuals
For individuals who use a calendar year as their tax year, the following are the most important 2017 tax due dates, including the last day to do taxes. 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.
Here’s a quick look at important dates for your 2017 tax return, due in 2018:

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, apply the deadlines by treating the first date of your fiscal year as Jan. 1 and moving the deadlines forward as needed. For example, if your fiscal year ends on Jan. 31 instead of Dec. 31, your 2017 tax year dates would all be moved back one month.
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 itself.
