Calendario con pines rojos marcando fechas importantes

Every January the same thing happens in thousands of Latino kitchens: someone sticks a magnet on the fridge with two or three handwritten dates —”April: taxes”— and then forgets about it until the calendar squeezes. The dates of tax season aren’t a mystery, but they are easy to tangle: one is for filing, another for paying, another for requesting more time, and each has its own rules.

This is the guide to stick on the fridge this year, with the dates of the 2027 season (tax year 2026) and, more importantly, what really happens when one slips by you.

When the 2027 season opens

Filing season opens in late January 2027. The IRS announces the exact date each year —usually in early January—. There’s no fixed day written in stone. What is fixed is the pattern: from that day on, the IRS starts accepting and processing electronic returns for tax year 2026.

The practical advice: don’t file on day one just for the sake of it. Wait until you have all your documents (W-2s, 1099s, interest statements) before sending anything. Filing early with incomplete papers doesn’t speed anything up: it only guarantees a correction later.

The deadline: Thursday, April 15, 2027

April 15, 2027 (Thursday) is the deadline to file your federal return for tax year 2026. The same date is for paying what you owe: filing and payment are due together.

Two exceptions to keep in mind:

  • If you live outside the country, you automatically get two extra months to file (until June 15), although payment is still due in April.
  • If you request an extension with Form 4868, the filing date moves to October 15, 2027. Payment, again, doesn’t move: it’s still due in April.

And a calendar detail: when April 15 falls on a weekend or federal holiday, the IRS moves the date to the next business day. This year the 15th is a Thursday: worth remembering for future seasons.

The February exception: refunds with EITC and child credit

If your refund includes the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit, the law —known as the PATH Act— prohibits the IRS from issuing that refund before mid-February, no matter how early you file. So expect: if you filed in late January and your refund includes one of these credits, the “late” arrival isn’t an error or a problem with your return. It’s the law working as designed.

Quarterly estimated payments: the other dates nobody marks

If you work for yourself, you probably owe taxes every quarter, not just in April. The typical estimated payment dates for tax year 2027 are:

  • April 15, 2027: first payment of 2027
  • June 15, 2027: second payment
  • September 15, 2027: third payment
  • January 15, 2028: fourth and final payment of 2027

Notice the mental trap: the first estimated payment of 2027 is due the same day as the 2026 return filing. April is the heaviest month of the tax calendar, and that’s why it’s worth planning it from March, not the week of the 15th.

What happens if a date slips by you

  • Not filing: the failure-to-file penalty can be 5% of the unpaid tax for each month of delay, up to a maximum of 25%. It’s the most expensive penalty in the system: filing late without an extension is the worst scenario.
  • Filed but didn’t pay: the failure-to-pay penalty is smaller (0.5% monthly, up to 25%), plus interest.
  • Hurts less than not filing: you requested an extension but forgot to file in October: the unused extension leaves you as if you’d never requested it, with the months of accumulated interest.

The golden rule is simple: if you can’t pay, file anyway. The failure-to-file penalty is about ten times bigger than the failure-to-pay penalty. Filed paperwork + pending payment always beats nothing filed.

What to do today, in order

  1. Write down the dates that apply to your case: season opening (late January), April 15, October 15 if you request an extension, and the quarterly payments if you work for yourself.
  2. Gather your documents before the season opens: W-2s, 1099s, interest statements.
  3. If you think you won’t make it by April 15, request the extension in time: step-by-step Form 4868 guide.
  4. If your refund includes the EITC, set aside the February expectation: it will arrive after mid-month, without that meaning there’s a problem.
