Fiscal Year Vs Calendar Year: What’s Best for Your Business?


For tax, accounting, and even budgeting purposes, it’s important to know the difference between a fiscal year vs calendar year. A fiscal year doesn’t always align with its calendar counterpart. For example, Microsoft corporation winds up its fiscal year at the end of June.

As the name suggests, a calendar year begins on January 1 and ends on Dec 31. Amazon uses this calendar year system for tax reporting.

What is a fiscal year?

A fiscal and a calendar year are two different things. A fiscal year is the 12-month accounting period for a business cycle. A fiscal year-end date is different than the end of the calendar year. It’s the financial reporting cycle business uses for tax purposes. That’s one of the key differences.

What is a calendar year?

A calendar year is a one-year period starting on January 1 and ending on December 31.

Differences Between a Calendar Year Vs Fiscal Year

There are several differences between a fiscal year and a calendar year.

  • The calendar year begins on New Year’s Day and follows the Gregorian calendar. In the business sector, a calendar year can be utilized for tax returns, starting on January 1 and concluding on December 31.
  • The fiscal year starts on any date. They require more complicated financial reporting. Fiscal years need to end 365 days later or within a twelve-month period.
  • The calendar year is more aligned with IRS systems.
  • A calendar year may not always yield the most precise financial reports. For seasonal businesses, utilizing a fiscal year enhances the accuracy of income and expense reporting.

Can you change your tax year with the IRS?

The IRS bases its operations on the calendar tax year. If you choose to follow your own fiscal year, you will need to adjust your deadlines accordingly. Specifically, your payment is due on the 15th day of the fourth month following the conclusion of your selected fiscal year.

Seasonal business taxes differ from those paid by individuals following a more conventional calendar year. For most taxpayers, the deadline is April 15th.

But of course, that’s not always the case. This startup checklist also has some other matters you should consider about the finances of your business.
