Article 27 explained in plain English
This article regulates the treatment of inventory for tax purposes, which matters to commercial and industrial establishments:
- Stocktaking records (paragraph a): a taxpayer who holds inventory must open stocktaking records for it and keep them.
- The deduction (paragraph b): the cost of goods sold during the tax year is deducted.
- The calculation (paragraph c): cost of goods sold = opening stock + the cost of purchases during the year − the value of closing stock.
- The cost of inventory (paragraph d): someone using the cash basis calculates it by the prime (direct) cost method or by total costs, and someone using the accrual basis calculates it by the total costs method only.
- Valuing closing stock (paragraph e): at the lower of book cost or market value on that date, with book cost calculated by the weighted average method. Another method may be used after written permission from the Authority, and the chosen method may not be changed except with its approval.
The practical effect is that valuing closing stock affects profit directly: the lower its value, the higher the cost of goods sold and the lower the tax base, which is why the Law set fixed rules for valuing it.
To apply these rules to your establishment, it is advisable to consult a lawyer specialized in tax and commercial matters.
Practical example
An appliance shop in Dammam started the year with goods worth SAR 300,000 and bought goods during it for SAR 700,000, and the value of its goods at the end of the year is SAR 200,000 after valuing them at the lower of cost or market. The cost of goods sold that may be deducted is SAR 800,000.
