Whether you’re a salaried employee, a freelancer, a small business owner, or a corporation, understanding and adhering to tax deadlines will help you effectively manage your tax obligations throughout the year, ensure compliance with tax laws, and avoid unnecessary penalties. But we know you have plenty going on in your life, and keeping track of every IRS tax deadline may not always be top of your agenda.
To make things easier for you, this comprehensive guide contains essential tax deadlines for the year 2025.
Make sure your 2025 calendar is updated with these tax deadlines, dates, and possible extensions:
If you read nothing else, know the below:

Tips to help you make sure you get everything done right and on time:
- Save future time and trouble with a new S Corp by getting your accountant the proper paperwork showing that your S Corp status has been accepted.
- An extension will extend your time to file, but not your time to pay. If you think you might owe money this year but will need to extend, give your accountant as much information as possible.
- Avoid the temptation to ignore that 1099 you received this year, or leave out things like bank interest or dividends that may seem insignificant to you. Companies report this income information to the IRS and it is matched by computer to what you file. If you choose not to file altogether, the IRS may choose to file for you. The IRS is the worst tax accountant you could have when it comes to finding deductions and credits.
- Ask questions. The tax law is constantly changing. If you think something might be deductible, or should be deductible, it never hurts to ask your accountant.
Working with a tax professional can help you understand your eligibility for deductions and credits, reconcile your information, and submit an accurate tax return that is likely to result in a quicker refund.
