What it means
Trading never stops, so accountants impose artificial cut off points to make performance measurable. Each fiscal period has a defined start and end date, and everything earned or incurred between those dates belongs to it.
The choice of end date is largely a business decision rather than an accounting one. Companies pick a year end that suits their trading pattern, usually a quiet point when stock is low and staff have time to count it.
A retailer might close its year in January after the festive season, while an agricultural business might close after harvest. Once chosen, the year end is difficult to change and usually requires notifying the tax authority and the company registry.
Within the year, most businesses report monthly, though the shape of those months varies. Some use calendar months, while others use a 4-4-5 calendar in which each quarter is split into two four week periods and one five week period, giving thirteen weeks of equal weekday counts.
That structure makes week to week comparisons fairer for businesses where weekend trading dominates. Cut off is where most fiscal period problems appear.
If an invoice for December work is recorded in January, or stock delivered on the last day of the year is counted but the supplier invoice is not, the results for both periods are wrong. Auditors spend a good deal of time testing transactions either side of the year end for exactly this reason.
Costs that span periods have to be apportioned rather than dumped into whichever period the payment happened to fall in. An annual insurance premium, a software licence or a rent payment is spread across the periods it covers, using prepayments and accruals to move the cost to where it belongs.
In practice
Real-world examples.
Example
A UK based fashion retailer runs its financial year from February to January, so the Christmas trading peak and the January sale fall inside the same set of results. Closing in January also means the annual stock count happens when the shelves are at their emptiest.
Example
A university sets its fiscal year to end on 31 July, aligning the accounts with the academic calendar. Tuition income received in advance for the coming year is held as deferred income rather than counted in the year it was banked.
Example
A software company invoices a customer $120,000 for a twelve month licence beginning in October. Only three months of that, $30,000, belongs to the fiscal year ending in December, and the other $90,000 is carried forward as deferred revenue.
Think of it
“A fiscal period is any chunk of time you're measuring-monthly, quarterly, or annual reporting periods.
Formula
Calculation
Amount charged to a fiscal period = annual amount x (days in the period / days in the year).
A logistics company pays an annual insurance premium of $73,000 and reports on calendar quarters. Its second quarter covers April, May and June, which is 30 + 31 + 30 = 91 days, and the year has 365 days.
The daily cost is $73,000 / 365 = $200, so the insurance charged to that quarter is $200 x 91 = $18,200. The remaining $54,800 sits in prepayments on the balance sheet and is released into the three other quarters as they occur, which is what matching a cost to its period means in practice.Case study
Seen in the real world.
The following is an illustrative and entirely fictional example. Thornbury Garden Supplies, an invented horticultural wholesaler, ran a fiscal year ending on 31 March, which fell right in the middle of its busiest trading season. Stock counts had to happen while lorries were loading, and the finance team routinely spent April untangling cut off errors.
Worse, the year end split the spring selling season across two fiscal years, so no single set of accounts ever showed a complete trading cycle. Year on year comparisons were close to meaningless because a warm March pulled sales into one year while a cold one pushed them into the next.
In this fictional case the company moved its year end to 31 October, once the season had finished and warehouses were nearly empty. The transitional period was seven months long and had to be explained carefully to the bank, but from then on each fiscal year contained exactly one full spring, and the audit was completed three weeks faster.
Watch out
Common mistakes.
- Assuming a fiscal year must follow the calendar year, when the end date can be set to suit the business's own trading rhythm.
- Recording a cost in the period the cash left the bank rather than the period the benefit was received.
- Comparing a 4-4-5 period against a calendar month and treating the difference in trading days as a performance change.
Questions
People also ask.
Can a company change its fiscal year end?
Yes, though it usually requires notifying the registry and the tax authority, and it creates one odd length period that must be explained.
What is the difference between a fiscal period and an accounting period?
In everyday use they mean the same thing, though fiscal period often carries a tax or statutory flavour while accounting period is the more general term.
Why do some companies use a 52 or 53 week year?
It keeps each period the same number of days and the same weekday mix, which makes retail and hospitality comparisons far cleaner, at the cost of an extra week every five or six years.
