Fiscal Year

What Is a Fiscal Year?

While most people think of the year as January to December, businesses can choose any 12-month period as their fiscal year. A retail company might use February to January so that the holiday season falls in the middle of their fiscal year rather than at the end. The U.S. federal government uses October to September.

For example, many retail businesses end their fiscal year on January 31. This way, holiday sales are fully accounted for and end-of-year clearance sales are complete before they close the books. Apple's fiscal year ends in September, aligning with its major product launch cycle.

Why It Matters for Your Business

Choosing the right fiscal year can simplify financial reporting and improve the quality of your financial analysis.

• Business cycle alignment: If your business has strong seasonal patterns, aligning your fiscal year so the busy season falls in the middle provides cleaner financial data.
• Tax planning: Your fiscal year determines your tax filing deadlines. Choosing a fiscal year that gives you more time after your busiest period can reduce tax preparation stress.
• Comparison accuracy: Financial comparisons are more meaningful when fiscal years align with natural business cycles rather than arbitrary calendar dates.

Most small businesses and sole proprietors use the calendar year (January to December) for simplicity, as it aligns with personal tax filing. Changing your fiscal year requires IRS approval and should be discussed with a tax professional.
