What is an accounting period?
Accounting period (definition)
An accounting period is any time frame used for financial reporting. Transactions that fall within a given date range form part of the statements or reports for that accounting period.
An accounting period, or reporting period, is often 12 months. There may be different accounting periods for various business tasks. For example, you may have one for income tax, another for sales tax, and still others for business reporting.
Some common accounting periods are a calendar year (January 1 through December 31) or a calendar quarter (January 1 through March 31).
Annual accounting periods don’t have to start in January. Nor do monthly accounting periods have to start on the first of the month.
