Why is April 15 Tax Day?

April 15, 2012

Happy Tax Day!

Sorry. I didn't mean to give you a heart attack. But I'm pretty sure that by now every taxpayer knows that this year the tax-filing deadline is Tuesday, April 17.

When April 15 falls on a Saturday, Sunday or federal holiday, we get until the next business day to file our returns.

So instead of scrambling to get our 1040s filed by midnight today, Sunday, April 15, our federal tax returns normally would be due tomorrow, Monday, April 16.

But that's Emancipation Day, a holiday in the District of Columbia.

And as we learned when this holiday and Tax Day coincided back in 2007 and 2011, a federal statute enacted decades ago says that holidays observed in the District of Columbia have an impact nationwide, not just in D.C.

15 April deadline for federal tax filingSo the federal tax filing deadline gets moved to the next business day. Tuesday, April 17, 2012.

Still, April 15 is the official Tax Day. So that's today's By the Numbers figure.

Just how did the middle of April come to be one of America's most hated days?

It used to be March 1. That's the tax deadline set when the 16th Amendment, which authorizes the income tax (please, tax protesters, save your energy and don't bother emailing your lunatic frivolous arguments), was ratified on Feb. 3, 1913.

Congress decided to give taxpayers back then a year plus a few weeks to get used to the income tax idea.

When the Revenue Act of 1918 was enacted, a provision in that law moved the filing deadline to March 15.

But Congress couldn't stop fiddling with the filing calendar.

In 1955, additional tax-code revisions pushed the date to April 15.

It probably wasn't a bad idea. Moving the filing deadline deeper into the calendar year spread out the Internal Revenue Service's workload.

But there also was a likely fiscal reason for moving Tax Day.

As more middle class Americans filed taxes in the mid-50s, Uncle Sam was issuing more refunds. Pushing the deadline back gave the government more time to hold on to the money, Ed McCaffery, a University of Southern California law professor, told Fortune magazine.

Hello Tax Season 2026

Happy New Tax Year! Are you ready to file your 2025 tax return? I know, too early to ask. But Tax Day 2026 will be here before we realize it. The Internal Revenue Service deadline to file and pay any tax we owe is the regular April 15 date this year. It’s also Tax Day for most of the states that collect income taxes from their residents, which is most of the states! If that seems too far away right now, don’t worry. As is the case every tax season, the ol’ blog’s tips and other tax reminders should help all of us meet our state and federal responsibilities. Procrastinators also will want to keep an eye on the countdown clock just below. It tracks how much time we have until April’s Tax Day, just in case we put off our annual tax task until the absolutely final hours and decide we need to instead get an extension request into the IRS by that date. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
