Important Tax Deadlines

Key takeaways

For most Americans, federal income taxes are due on April 15 each year. Filing early is strongly recommended to reduce stress, avoid last-minute issues, and help protect against identity theft.
Tax season officially begins in late January, when the IRS starts accepting returns, and runs through the April 15 deadline. When you e-file your federal return, the IRS typically issues refunds within 21 days, provided there are no errors or processing delays. Paper-filed returns can take up to eight weeks or longer to process.
State tax refund timelines vary by state, but in most cases, electronic filing results in faster refunds than mailing a paper return.
Missing the filing deadline may lead to penalties and interest. However, filing as soon as possible can help minimize these costs. If you’re unable to pay the full balance by the deadline, the IRS offers payment plan options that allow you to pay over time.

To prepare your return, you may need documents such as W-2s, 1099s, a government-issued photo ID, last year’s tax return, and records for any deductions or credits you plan to claim. Our team at Du Tax Firm is here to help you every step of the way.

When is tax season?

Tax season begins when the IRS starts accepting tax returns—typically in late January—and runs through Tax Day on April 15. During this three-month period, most Americans prepare and file their tax returns, while those who need additional time may request a filing extension.

Tax season is also when taxpayers pay any taxes owed or arrange payment plans with the IRS if they are unable to pay the full balance by the deadline. The IRS offers several payment options, including short-term plans for balances paid within 180 days and long-term monthly installment plans for those who need more time. Du Tax Firm can help you choose the best option and ensure everything is set up correctly.

When are taxes due in 2026?

For most taxpayers, taxes are due on April 15, 2026.

Despite common misconceptions, April 15 is simply the final deadline to file, not the only day you can file. Waiting until the last minute often creates unnecessary stress and can lead to longer wait times for assistance, missing documents, and unexpected tax bills you may not be prepared to pay.

In most cases, filing earlier is better. Early filing gives you time to gather all required documents, plan for any taxes owed (or decide how to use your refund), and schedule time with a qualified Tax Professional who can help ensure you receive every dollar you’re entitled to.

Filing early can also help protect you from identity theft. The IRS reported flagging more than 1.9 million tax returns during the 2024 tax season for potential identity theft, involving an estimated $2–$4 billion in fraudulent refunds. When you file early, you reduce the opportunity for criminals to use your information to file a return in your name.

We encourage proactive filing to help you avoid last-minute issues, safeguard your identity, and enjoy a smoother, more confident tax season.

IRS refund schedule: When will I get my federal refund?

The IRS typically issues federal tax refunds within 21 days of receiving an e-filed return, as long as there are no errors or issues that require additional review. If you file a paper return, processing can take eight weeks or longer. Whether you file electronically or by mail, the sooner you file, the sooner you can receive your refund.

Refunds may be delayed if your return contains errors or missing information. To help avoid delays, it’s important to carefully review your return for accuracy before submitting it. If the IRS needs additional details to process your return, they will contact you directly.

If you want your refund as quickly as possible, the best approach is to file early, e-file your return, and choose direct deposit. You can track the status of your federal refund using the IRS “Where’s My Refund?” tool. 

What happens if I miss the tax deadline?

If you miss the tax filing deadline and owe taxes, you may be subject to penalties and interest—but don’t panic. While filing on time is important, there are steps you can take to reduce the financial impact if you file late.

If you owe taxes, it’s best to file your return as soon as possible. This helps limit IRS penalties, including the Failure to File penalty, typically 5% per month, and the Failure to Pay penalty, usually 0.5% per month, both based on the unpaid tax balance and capped at 25%. Interest will also accrue on any unpaid amount from the original due date until the balance is paid in full.

If you can’t afford to pay your full tax bill, file your return anyway and pay as much as you can. The IRS offers payment plan options that allow you to pay the remaining balance over time. Filing promptly—even without full payment—can significantly reduce penalties.

If you are due a refund, there is no penalty for filing late, but you must file your return to receive your money. Filing sooner ensures you get your refund without unnecessary delays.

In certain situations—such as natural disasters, serious illness, or other qualifying circumstances—you may be eligible for penalty relief if you can demonstrate reasonable cause for missing the deadline.

If you request a filing extension by April 15, 2026, you’ll have until October 15, 2026, to file your return. Keep in mind that an extension gives you more time to file, not more time to pay—any taxes owed are still due by April 15.

If you already know you won’t be able to file or pay by the deadline, taking action early is key. Filing an extension and setting up a payment plan before April 15, 2026, can help you stay compliant and avoid additional penalties.
