What is an accounting period?
Published
The accounting period is the unit of time results are measured over within the year - the month for management, the quarter for wider review, the year for final statements. An artificial slicing of continuous activity, but the one that makes the two most important questions possible: how did we do? compared to what?
The one governing rule
Every transaction is assigned to the period it accrues in - not when recorded, not when collected. From this rule branch all the adjusting entries (accruals, prepayments, depreciation) covered on their pages - and from it, the danger of late recording: a June invoice recorded in July lies to two periods at once.
Three periods not to confuse
| Al-Waha's length | Purpose | |
|---|---|---|
| Management period | A month | Reading performance, correcting course |
| Tax period | A quarter (quarterly filer) | The return - set by the authority, not you |
| Fiscal year | January-December | Final statements and the annual filing |
Their boundaries often coincide; their functions never merge - and the trial balance "dated exactly at the tax period end" (the VAT return page) is the distinction at work.
Frequently asked questions
Is a monthly period mandatory?
Mandates attach to the tax and annual ones; monthly is a management choice - but it is the difference between catching drift in weeks or in a year.
A transaction dated in a closed period just reached me?
Record it in the first open period with a reference to its origin - the closed period doesn't reopen (see period closing).
