When Are Taxes Due? 2021 Filing & Extension Deadlines

Tax filing deadlines can creep up on you, and there’s nothing more frustrating than having to pay a fine that could have been avoided.

Take a few minutes to save each relevant filing date to your calendar, and stay ahead of the IRS.

When is “tax day”?

The big “tax day” is usually April 15, 2021. This is when you have to file your taxes, but not pay! However, for individual tax filers in 2021, this has been changed to May 17, 2021.

The IRS has also announced it is giving victims of the winter storms until June 15th, 2021 to file and pay business returns normally due on March 15th and April 15th. More information can be found on the IRS website. This extension applies to Texas, Oklahoma, and Louisiana.

What’s the deadline to pay your taxes?

If you’re sending your return in via snail mail, the IRS considers your return “on time” if it’s addressed correctly, has enough postage, and is in the mail before the end of business on your filing deadline.

Otherwise, you can e-file your return before midnight on your tax filing deadline day.

If you’re self-employed, your business probably pays taxes in four sums throughout the year, rather than on one day. These are called estimated tax payments. The due date for these 2021 payments are April 15, June 15, September 15, and January 15 (2022).

When are 2021 tax extensions due?

You have right up until tax day to file for an extension. For individuals, that means you can still file for a tax extension right on April 15. The same goes for businesses: S corps and partnerships can still get an extension on March 15, and the last day for C corps to file for an extension is April 15.

2021 Tax Deadlines

Here is a detailed list of every tax deadline in 2021.

December 31, 2021

Tax moves deadline

Today is the final day to make any tax moves for the 2021 tax year.

Set up a solo 401 (k)

If you are self-employed, today is the deadline to set up a solo 401 (k).

When can I start filing taxes for 2020?

You can start filing your 2020 tax return after February 12, 2021.

When will I get my tax refund?

In 2018, 9 out of 10 e-filers received their refund less than 21 calendar days after their return was received by the IRS.

That’s not an IRS promise or anything. But in general, you can expect to get your tax refund 3-4 weeks after filing your return. That being said, these are unprecedented times. It’s impossible to say when you’d get your tax refund in 2021.

Paying your taxes late

Past your tax due date, you’ll have to pay a penalty for late payment. This amounts to an additional 0.5% of unpaid taxes every month until you pay your original tax bill (up to a maximum 25% of your total tax bill).
