It’s official: the IRS 2026 tax season has begun, and taxpayers can no longer afford to delay opening IRS letters or organizing their tax documents. The Internal Revenue Service has confirmed that it will start accepting federal tax returns for the 2025 tax year on January 26, 2026, with the filing deadline set for April 15, 2026.
This year’s filing season brings new tax law updates, updated deductions, and an opportunity for higher refunds. However, failing to act on IRS notices could cause refund delays or even penalties for inaccurate or late filings.
“Getting ready early, organizing your W-2s, 1099s, and other income forms will help avoid mistakes that can delay refunds or trigger audits,” said tax advisor Elaine Parker. “IRS envelopes often contain critical documents or alerts that can affect your filing.”

Here’s what taxpayers should know now and why early preparation in January can make a big difference.
IRS 2026 Tax Season Overview
| Milestone | Date (2026) | What It Means |
|---|---|---|
| IRS begins accepting returns | January 26, 2026 | E-filing and refund processing officially start |
| Employers must issue W-2s | By February 1, 2026 | Contact employer if your W-2 is delayed |
| Tax filing deadline | April 15, 2026 | File on time to avoid penalties |
| Extension filing deadline | October 15, 2026 | Only valid if requested before April 15 |
Even if you request an extension, tax payments are still due by April 15. Missing the payment deadline could result in interest charges or late fees.
Why January IRS Envelopes Are So Important?
Every January, millions of taxpayers receive IRS mail regarding:
- Missing or incorrect income statements (W-2, 1099, 1099-K, or 1099-DA)
- Identity verification or security PINs
- Tax balances or payment plan information
- Updates related to deductions and tax law changes
Ignoring these letters or digital notices can cause delays in refund processing or even trigger compliance issues. Setting up your IRS online account allows you to monitor any alerts or correspondence in real time.
“The biggest mistake we see is taxpayers ignoring those early January letters,” said Howard Gleckman, Senior Fellow at the Urban-Brookings Tax Policy Center. “They often contain information that can prevent costly filing errors later.”
Why Filing Early Is Smarter in 2026?
1. Faster Refunds with Direct Deposit
Taxpayers who file electronically and choose direct deposit can receive refunds within 10 to 21 days of IRS acceptance. Paper checks may take significantly longer.
2. Access to New Tax Law Benefits
The One Big Beautiful Bill Act introduces new deductions in 2026, including expanded credits for education expenses, car loan interest, and earned income. Filing early helps ensure you capture these benefits accurately.
3. Avoiding Errors and Duplicate Filings
Waiting for all your documents before filing prevents errors that can trigger refund holds or audits.
4. Early Filing Prevents Identity Theft
Filing early also reduces the risk of identity fraud since it locks in your tax information before criminals can file false returns in your name.
Key Steps to Prepare Before You File
1. Gather Your Documents Early
Make sure you have:
- All W-2s from employers
- 1099s from freelance or gig work
- 1099-DA or 1099-K for digital assets or payment app income
- Deductible expense receipts (medical, education, charitable, or business-related)
2. Create or Update Your IRS Online Account
Your online account allows you to view prior returns, balances, payment plans, and digital notices in one place.
3. Double-Check Your Direct Deposit Information
Ensure your bank account details are accurate to avoid delays in refund disbursement.
4. Choose E-Filing Over Paper
E-filing is faster, safer, and more reliable than mailing paper returns.
Common Mistakes to Avoid
| Mistake | Why It Matters |
|---|---|
| Filing without all forms | Causes delays or IRS rejections |
| Wrong bank details | Refunds may be sent to the wrong account |
| Ignoring IRS notices | Can lead to penalties or missed corrections |
| Forgetting new deductions | You could lose refund opportunities |
| Filing too late | Penalties and interest may apply |
Expert Insights
“The IRS is modernizing quickly,” explained Janet Morales, a certified public accountant. “That means taxpayers need to stay proactive. The earlier you file, the smoother your refund process will be.”
David Anderson, a former IRS agent, added: “Many taxpayers assume that IRS mail is bad news, but it’s often informational, sometimes even beneficial. Ignoring it is never the right move.”
Final Thoughts
Tax season 2026 is now in motion, and opening your IRS mail early is the first step to a smooth refund experience. The earlier you review your forms and file your taxes, the less likely you’ll face errors, identity fraud, or refund delays.
As tax consultant Elaine Parker emphasized, “January is not the month to ignore your mailbox, it’s the month to secure your refund.”
Prepare early, e-file with accurate information, and make sure your IRS correspondence doesn’t go unopened this season.
