Consequences of Missing Tax Deadlines
Should you miss a tax deadline, you’re likely to face consequences such as interest charges, penalties, and even potential loss of refunds owed. The IRS doesn’t take kindly to tardiness when it comes to business taxes due. If you fail to file, the tax bill can quickly increase due to interest and penalties.
The consequences of missing tax deadlines can be severe. For instance, if you miss an estimated tax payment deadline, the penalties and interest charges depend on how much you owe and how late the payment is. It’s not just about the financial impact; your business reputation can also take a hit.
Let’s say you find yourself unable to pay your tax bill in full. It’s crucial you file your taxes as soon as possible anyway and consider setting up an installment plan for the remaining balance. Remember, failure to file is a serious issue.
Electronic filing is your best bet. It’s the fastest, most accurate way to file your taxes. And if you think you’ll miss a deadline, don’t panic. Request an extension. It’s always better to preemptively act than face the consequences of missing tax deadlines
The Internal Revenue Service (IRS) will apply a Failure to File penalty to all businesses that submit their 2025 tax return late. The Failure to File Penalty is:
- 5% of the business’s unpaid taxes for each month or part of a month that a tax return is late. The penalty won’t exceed 25% of your unpaid taxes. However, the IRS charges interest on penalty fines.
- Generally speaking, it might potentially be wise to make a bit of a larger extension payment so that one will have a refund and definitely avoid penalties and then know that the additional refund will get rolled into their Q1 estimate for the next year (two birds with one stone).
The best way to avoid penalties from filing a late tax return is to apply for a tax extension on time.
What Is a Tax Extension?
A tax extension is an application filed with the IRS to get an additional six months to submit a tax return. The application can be filed electronically or on paper and must be done before the original tax deadline.
The extension typically gives a business six months to file its taxes. While extensions can provide breathing room, they don’t delay the tax payment due dates. So, even if you’ve got an extension, make sure to estimate and pay any owed taxes by your original due date.
Penalties and interest will still be charged on any outstanding balances, so filing a tax extension is crucial if you think you might not make the original deadline.
Requesting an Extension for Tax Filing
You’ll often find that you need a bit more time to prepare your business taxes properly; fortunately, the IRS allows businesses to request a six-month tax filing extension. This tax extension gives you breathing room if you’re behind on your paperwork, but remember, it’s an extension to file, not an extension to pay what you owe.
- Partnerships and S-Corps must file by March 15, 2025. If you need more time, use Form 7004 to request an extension to September 15, 2025.
- C-Corps have until April 15, 2025, to file. With Form 7004, the deadline extends to October 15, 2025.
- The extension doesn’t delay the date to pay taxes. You may face penalties and interest if you miss the filing deadline and owe taxes.

When are taxes due for quarterly payroll payments?
In addition to annual business tax deadlines, businesses are also responsible to know when taxes are due for quarterly payroll taxes. These taxes include Social Security, Medicare, and federal income tax withholding from employees’ wages.
For 2025, the due dates for quarterly payroll taxes are as follows:
- Quarter 1 (January 1 – March 31): April 30, 2025

Deadline to Send Tax Forms to Contractors
A business that works with contractors will need to report non-employee compensation using Form 1099-NEC. In this situation, the business must send Form 1099-NEC to the contractor no later than January 31.
When preparing your 2024 tax return, be sure to send the Form 1099-NEC to all contractors hired in 2024 and the IRS no later than January 31, 2025.
