Running a small business means keeping track of much more than sales and expenses. Tax deadlines are an important part of managing your business, and missing one can result in penalties, interest, or unnecessary stress.
The exact deadlines that apply to your business depend on how your business is structured, how you report income, whether you have employees, and which taxes you are responsible for. However, understanding the major deadlines can help you stay organized throughout the year.
Income Tax Deadlines
For many calendar-year taxpayers, April 15 is the primary federal and North Carolina income tax deadline.
For example, the 2025 North Carolina individual income tax return was due April 15, 2026. North Carolina also generally follows an April 15 deadline for calendar-year individual taxpayers.
The deadline that applies to a business can be different depending on its tax classification.
Partnerships and many S corporations generally have an earlier filing deadline than individual returns. Calendar-year partnership and S corporation returns are generally due March 15. C corporations generally have a different filing deadline.
If your business operates on a fiscal year rather than a calendar year, your deadline may also be different.
Because business tax deadlines depend on your specific circumstances, it is important to know which returns your business is required to file rather than assuming every business follows the same schedule.
Estimated Tax Payments
Many small business owners do not have taxes withheld from their business income the way employees have taxes withheld from their paychecks.
Instead, they may need to make estimated tax payments throughout the year.
Estimated payments are generally made four times a year. For individuals, the federal estimated tax schedule generally falls around April 15, June 15, September 15, and January 15 of the following year.
North Carolina also generally uses quarterly estimated tax payments for individuals who are required to make them.
Estimated tax requirements can become particularly important when your business income changes significantly during the year.
Payroll Tax Deadlines
If you have employees, payroll creates another set of tax responsibilities.
Employers generally need to withhold federal income tax and Social Security and Medicare taxes from employee wages. Employers also have responsibilities for their share of Social Security and Medicare taxes and federal unemployment taxes.
Payroll tax deposits have their own deadlines, and those deadlines can vary depending on the amount of payroll taxes your business has accumulated.
Employers also need to file payroll tax returns and provide employees with required year-end forms.
This is one reason accurate and timely payroll processing is so important for small businesses.
1099 Deadlines
Businesses that pay certain independent contractors may have information reporting requirements.
The deadline for issuing a Form 1099 and the deadline for filing it with the IRS can depend on the type of payment being reported.
Rather than waiting until the end of January to determine whether you have reporting requirements, it is a good idea to keep accurate vendor records throughout the year.
What About Extensions?
An extension can provide additional time to file certain tax returns, but it generally does not mean you have additional time to pay taxes that are due.
North Carolina specifically notes that an extension of time to file does not automatically extend the time to pay tax.
If you expect to owe taxes, planning for the payment by the original deadline is important even when you need additional time to complete the return.
Don’t Wait Until the Deadline
One of the easiest ways to make tax deadlines more stressful is to wait until the last minute.
Keeping your accounting records current throughout the year can make it easier to estimate tax payments, prepare returns, identify missing information, and make informed business decisions.
A good accounting system also makes it easier for your accountant to identify upcoming responsibilities before they become urgent.
