Tax season: that time of year when forms, refunds, and deadlines start creeping into everyone’s inbox. But let’s be honest — figuring out exactly when tax season starts (and what you need to do) isn’t always clear.

If you’re wondering when to file, what documents to gather, or how to avoid last-minute stress, this is the guide for you.

Whether you’re a first-time filer, self-employed or just trying to get ahead, we’ll break down the key dates and what to expect for the 2025 tax season in plain English.

When Does Tax Filing Season Start?

Each year the Internal Revenue Service (IRS) confirms the office start date — usually mid to late January — when it begins accepting returns. To file a tax return for 2025, the IRS will begin accepting returns on January 27, 2026.

Even if you have all the documents, filing before this date isn’t possible. 

The IRS plans to add improvement tools to enhance the filing experience. Some of the tools include voice virtual assistants, expanded features on the IRS individual online account and more access to tax forms through tablets and cell phones. 

What’s the Tax Filing Deadline?

This one’s easier to remember:

Tax Day is Tuesday, April 15, 2026

That’s the deadline to:

• File your federal income tax return
• Pay any taxes you owe
• Request a filing extension, if needed

Important: An extension gives you extra time to file, but not to pay. You could face late fees and interest if you owe taxes and miss the April 15 payment deadline.

Exceptions: If you live in Maine or Massachusetts, your due date is April 17, 2026, thanks to regional holidays like Patriots’ Day and Emancipation Day.

Why File Early?

There are key advantages to filing your taxes early. These advantages include: 

• Faster refunds: The sooner you file your return, the quicker you will receive your refund or the sooner you will learn how much you owe. 
• More time to resolve issues: Instead of waiting until the last minute, you can find out if you need to file an amendment or if you need to submit more documents. 
• Better access to tax pros: You can shop around for different tax professionals and find the right fit for your needs and personality. 
• Less risk of errors: Preparing your taxes early minimizes the chances of mistakes on your return. 

Callout Reminder: Avoid filing too early — missing documents can force you to amend your return later.

How To Prep for Tax Season Like a Pro

Want to make this the year you don’t scramble at the last minute? Here’s a quick checklist to keep things simple:

• Gather the essentials: This includes W-2s, 1099s, investment and bank statements, student loan interest, mortgage info and any receipts for deductions or credits.
• Organize your records early: Create a tax folder (physical or digital) so you’re not digging through drawers in April.
• Consider major life changes: Did you get married? Have a baby? Start a side gig? All of these can affect your taxes.
• Use the IRS Tax Withholding Estimator: It’s a free tool that can help you make sure your W-4 and estimated taxes are accurate. Check it out here.
• Choose your filing method: Whether you go the DIY route with online software or hire a tax professional, now’s the time to figure that out — not when the deadline is days away.

What Happens After You File?

Once your return is submitted, here’s what usually happens:

If you e-file and use direct deposit:

• The IRS generally acknowledges your return within 72 hours
• Most refunds arrive within 21 days

If you mail your return:

• Processing can take 6 weeks or more
• Refunds are slower, and it’s harder to track

You can check your refund status using the IRS Where’s My Refund? tool.

Earned Income Credit or Additional Child Credit Filing

Those who claim the Earned Income Tax Credit (EITC) and Additional Child Tax Credit (ACTC) can expect to get their refunds by the end of February, provided they filed electronically, choose direct deposit and don’t have any problems with their returns.

That’s because, by law, the IRS can’t issue EITC or ACTC refunds before mid-February — and that goes for the entire refund, not just the portion attributed to the EITC or ACTC.

What About State Tax Deadlines?

Most states stick with the federal filing deadline: April 15, 2025. However, a few have different rules or extended deadlines due to state holidays or emergencies.

Want to be sure? The best move is to visit your state’s Department of Revenue website for official deadlines and filing instructions.

Here are a few states with special deadlines in 2025:

• Maine: April 17
• Massachusetts: April 17
• Hawaii: Sometimes offers a later deadline — check local updates

If you moved to a new state or worked in multiple states, don’t forget: you may need to file more than one state return.

Common Mistakes To Avoid This Tax Season

Here are some of the most common (and avoidable) tax-time slipups:

• Forgetting a form – Wait until you’ve received all your tax docs before filing.
• Overlooking side income – Even occasional freelance or gig income must be reported.
• Filing too late – Missing the April deadline without requesting an extension could mean penalties.
• Not updating your W-4 – If your income or family situation changes, make sure your tax withholding reflects that.
• Relying only on last year’s info – Tax laws change. Don’t assume everything is the same.

Final Thoughts to GO: Your 2026 Tax Season Game Plan

Let’s bring it all together. When is tax season in 2026? It starts on January 21, 2026, and ends on April 15, 2026, for most people.

Here’s your game plan:

• Start early (but wait until you have all your paperwork)
• Use online tools and estimators to double-check your math
• Consider filing electronically with direct deposit to get your refund faster
• Stay organized and don’t be afraid to ask for help from a tax professional

A little planning now means way less stress later and possibly a bigger refund in your bank account.
