Prepaid expense accounting exists to address timing differences between cash payment and service consumption. Under accrual accounting, expenses are recognized in the period in which goods or services are consumed, regardless of when cash is paid. Where payment precedes consumption, an asset is recognized and subsequently expensed as the benefit is received.

 Under IFRS, this principle is articulated through the Conceptual Framework and reflected in IAS 1, which requires entities to present expenses in the period in which the underlying economic benefits are consumed rather than when cash is paid (IASB, 2018; IASB, 2023a). US GAAP applies the same principle through accrual accounting and the definition of assets and expenses in the FASB Conceptual Framework, with prepaid expenses treated as assets that provide probable future economic benefit (FASB, 2010).

 A common example is rent paid partway through a month, where a portion of the payment relates to the current accounting period and the remainder relates to a subsequent period. Prepaid expense accounting ensures that the expense is matched to the periods benefiting from the service.
