What Is an Accounting Period?

An accounting period is the span of time, usually 12 months, used by a business to record and report financial transactions.

How an Accounting Period Works

The accounting period concept, also called the periodicity concept , assumes that a business’s ongoing operations can be divided into equal, discrete periods. Each period captures all revenues earned and expenses incurred, allowing stakeholders to assess profitability and trends over time.

Types of Accounting Periods

Calendar Year: Runs from January 1 to December 31. Most individuals and many businesses follow this period.
Fiscal Year: Any 12-month period ending on a date other than December 31, such as April 1 to March 31, common in India.
Custom Accounting Periods: Shorter or longer cycles tailored to seasonal operations or industry-specific needs (e.g., 4-4-5 weeks for retail).

Requirements for Accounting Periods

Consistency is critical for accurate reporting.
Accrual Method of Accounting: Records transactions when they occur, not when cash is received or paid.
Revenue Recognition Principle: Revenue is recognized when earned within the period.
Matching Principle: Expenses are matched to the revenues they helped generate.

Is an Accounting Period Always 12 Months?

No. While many use a 12-month cycle, some adopt shorter interim periods (monthly, quarterly) for internal reporting. However, annual statements and tax filings generally require a 12-month cycle.

Two Types of Annual Accounting Periods

Calendar Year: January 1 to December 31.
Fiscal Year: Any 12-month span ending on a chosen date, such as March 31 or June 30.

What Happens at the End of an Accounting Period?

Books are balanced and financial statements are prepared.
Adjusting entries are made for accrued revenues and expenses.
Temporary accounts (revenues, expenses) are closed to retained earnings.
Management reviews results to plan for the next period.
