Choosing Your Fiscal Year: A Guide for US Small Businesses

When you start a US business, one of the most fundamental decisions you’ll make is choosing your fiscal year. This 12-month accounting period serves as the foundation for all your financial records, reports, and tax filings. While many US small businesses simply default to a calendar year, strategically choosing a different fiscal year can offer significant operational and financial advantages. Professional accounting services in the US can be critical to navigating this process successfully.

Here’s what you need to know to make an informed decision for your US business.

1. Calendar Year vs. Fiscal Year: The Basics

Your fiscal year is your business’s annual accounting period.

• Calendar Year: This is the most common choice, running from January 1 to December 31. It aligns with individual tax filing and is the default for most sole proprietors.
• Fiscal Year: This is a 12-consecutive-month period ending on the last day of any month other than December. The choice is often based on what is known as your “natural business year.”

2. The Power of a “Natural Business Year”

A natural business year is a fiscal year that ends when your business activity is at its lowest. This is typically after your busiest season, when inventory levels are at their minimum and cash flow from the peak season has stabilized.

Why a natural business year can be beneficial:

• Simplified Accounting: Closing your books and counting inventory is far easier during a slow period. This reduces stress and the risk of errors while your team is less busy.
• Accurate Financial Reporting: Aligning your fiscal year with your complete operating cycle—from pre-season expenses to post-season revenue—provides a more accurate picture of your annual performance. For example, a landscaping company might choose a fiscal year ending in late fall or early winter, after the season has concluded.
• Better Tax Planning: You can complete your year-end financial tasks and tax preparation during a less hectic time, allowing you to focus on your business during its peak season.

3. How Business Structure Affects Your Choice

The type of business entity you operate will have a major impact on your ability to choose a fiscal year.

• Sole Proprietorships: For a sole proprietor, the business and the individual are one in the same for tax purposes. Therefore, you are generally required to use a calendar year, which aligns with your personal tax filing.
• Partnerships & S-Corporations: These “pass-through” entities are also typically required to adopt a calendar year, as their income and losses are passed through to the owners’ individual tax returns. A partnership or S-Corp can apply for IRS approval to use a different fiscal year, but it must demonstrate a valid business purpose.
• C-Corporations: This business structure has the most flexibility. A C-Corporation can freely choose any 12-month fiscal year that aligns with its natural business cycle without needing prior IRS approval, as long as it is done with its first tax return.

4. The Process for Choosing or Changing Your Fiscal Year

When you file your first federal tax return, you establish your fiscal year.

• New Businesses: You adopt your tax year by simply filing your first income tax return using that year.
• Changing Your Fiscal Year: Changing your fiscal year after your first tax return can be a complex process that requires IRS permission. This often involves filing Form 1128, Application to Adopt, Change, or Retain a Tax Year. The IRS will generally grant permission if there is a valid business reason for the change, such as aligning with a natural business year.

Summary

Choosing the right fiscal year for your US business is a strategic decision with lasting implications. While the calendar year is the default for many US small businesses, opting for a fiscal year that aligns with your natural business cycle can streamline accounting, improve financial reporting, and provide clearer insights into your company’s performance. Always be mindful of the IRS regulations specific to your business entity. Navigating these choices and understanding the tax implications is a key part of good financial stewardship. If you’re unsure which option is best, professional accounting services in the US can provide the guidance you need.
