It is a new year—2025—and we should be aware of the important tax deadlines introduced by the IRS. Marking these dates can help you stay informed during the tax seasons, whether as individuals or in business tax filings.

When can you start filing your taxes in 2025?

The tax return acceptances of the IRS generally began in late January. For 2025, it started on the 27th of January, allowing taxpayers to prepare things ahead of time. However, the IRS, in past years, has started processing tax returns around January 23.

What is the deadline for estimated tax payments?

If you have income not subject to withholding—such as self-employment earnings, interest, or dividends—estimated tax payments are crucial. The final estimated tax payment for 2024 is due on January 15, 2025. This ensures you avoid penalties for underpayment.

When are W-2 and 1099 forms due?

The W-2 forms were supposed to be handed to the employees by their employers on January 31, 2025 (expiry date). This date is also the due date for Form 1099-NEC for independent contractors. Such will be valuable in ensuring correct filling during tax time to make sure you see your email on time.

What is the tax filing deadline for individuals?

The deadline to file your 2024 federal income tax return was on April 15, 2025. If you were unable to file by this date, you can request an extension, which grants you until October 15, 2025, to submit your return. However, it’s important to note that an extension to file is not an extension to pay any taxes owed. To avoid interest and penalties, ensure you pay any estimated taxes owed by April 15.

What are the key tax deadlines for businesses in 2025?

  • March 17, 2025: This is the deadline for S corporations and partnerships to file their 2024 tax returns or request an extension. It’s also the due date to provide Schedule K-1s to shareholders and partners.
  • April 15, 2025: C corporations must file their 2024 tax returns or request an extension by this date. Additionally, the first estimated tax payment for the 2025 tax year is due for individuals and businesses.
  • June 16, 2025: The second estimated tax payment for 2025 is due.
  • September 15, 2025: The third estimated tax payment for 2025 is due. This is also the extended filing deadline for S corporations and partnerships that requested an extension.
  • October 15, 2025: Extended deadline for individual tax returns. If you filed for an extension, this is your last day to submit your 2024 tax return.
  • January 15, 2026: The fourth estimated tax payment for 2025 is due.

How can you prepare for the 2025 tax season?

To make sure that the process is easy and simple for you, here are the steps you can take: 

  • Organize your documents: Gather all tax-related documents, including W-2s, 1099s, and receipts for deductions.
  • Make use of the IRS Online Tool: IRS Online Tools have been developed to help all taxpayers. This means one can simply create an IRS Online Account and thus access their tax history and payment status. 
  • Think of filing electronically: It will probably speed things up if you file electronically and have your return net deposit. 
  • Consult a tax specialist: It pays to see a tax professional if you have a complicated tax situation, both for correctness and compliance with the current tax laws. 

This way, you can be at ease with these dates and be well-prepared for the tax filing season with confidence.
