deferral

Sometimes cash changes hands before the related revenue or expense really belongs in the books. You pay a year of rent in January; a customer pays you in advance for work you will do over six months. The cash has moved, but the economic event it relates to is spread out over time. A deferral is the accounting device that holds that cash event on the balance sheet and releases it into the income statement gradually, period by period, as it is actually earned or used.

There are two kinds. A deferred (prepaid) expense is cash you paid in advance: it sits as an asset and is moved into expense as the benefit is consumed — prepaid rent, prepaid insurance, supplies. A deferred (unearned) revenue is cash you received in advance: it sits as a liability and is moved into revenue as you perform — a subscription, a deposit, an advance fee. In both cases the cash came first and the recognition of revenue or expense is deferred, meaning postponed, until later. The matching adjusting entry each period transfers just the earned or used-up slice.

Deferrals are one of the two great families of adjusting entries; the other is accruals, where recognition comes before the cash. Knowing which family you are in tells you immediately which way the entry flows: with a deferral you are unwinding an existing asset or liability into the income statement, never touching cash again. The pitfall is forgetting the deferral and either expensing or recognising the whole amount up front, which distorts every period the item spans.
