Tax season usually starts in late January, when the IRS begins accepting federal tax returns, and it typically runs through April 15, which is the standard filing deadline for most taxpayers. You can file as soon as you have all your tax documents, even weeks or months before April 15. Filing early can help you get your refund faster and avoid last-minute issues — as long as your return is accurate and complete.

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 in late January or early February.

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?

Tax Day is Wednesday, 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.

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. 

Why You Shouldn’t File Your Taxes Too Early

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

Key IRS Tax Deadlines To Keep in Mind

Below are the key federal deadlines for 2026 so you can stay on top of things:

Here are some important tips to help you prepare to file early.

Quarterly Estimated Payment Deadlines 2026

If you’re self-employed, freelance, or run a small business, you typically need to pay estimated taxes four times a year instead of having taxes withheld from a paycheck. Missing a deadline can trigger penalties and interest, even if you’re owed a refund later. The chart below outlines the 2026 quarterly estimated tax payment deadlines, along with key filing and extension dates to help you stay on track.

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 follow the federal tax filing deadline of April 15, 2026. However, a handful of states may set different deadlines or grant extensions due to state holidays, weather emergencies, or other local circumstances. To avoid surprises, it’s best to check your state’s Department of Revenue website for the most up-to-date filing deadlines and instructions.

One notable exception in 2026 is Hawaii, where the state tax filing deadline typically falls on April 20 — though taxpayers should still confirm in case of local changes.

If you moved during the year or earned income in more than one state, keep in mind that you may be required to file multiple state tax returns, each with its own rules and deadlines.

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.

Your 2026 Tax Season Game Plan

Tax season in 2026 typically begins in late January or early February and runs through April 15, 2026, which is the standard filing deadline for most taxpayers. Knowing the timeline makes it easier to plan — and avoid last-minute stress.

To stay on track, start preparing early but wait until you’ve received all your tax documents before filing. Use reputable online calculators or tax software to double-check your numbers, and consider e-filing with direct deposit if you’re expecting a refund — it’s usually the fastest option. Staying organized throughout the process and getting help from a tax professional when needed can make a big difference.

A little planning now can mean fewer headaches later — and potentially more money landing in your bank account.
