Stocktake: what is it?

Inventory of goods, materials and production entered in the tax ledger

A stocktake is the counting and valuation of goods, materials and work in progress. It is taken, among other dates, on 1 January and at year end, and its value affects costs.

Key answers

What it is
A list of goods for resale, materials, semi-finished products, work in progress, finished products, rejects and waste, with the quantity, price and value of each item. You enter the value of the stocktake in KPiR. The year's costs are then determined as: stocktake value at the start of the year plus purchases, minus the stocktake value at year end (explanations to the ledger layout).
Who it affects
Taxpayers keeping KPiR (§ 20 of the regulation), including those who lose the right to ryczalt during the year. The regulation on the revenue register of a flat-rate taxpayer does not require a stocktake.
When
On 1 January, at the end of each tax year, on the day the business starts during the year, and also on losing the right to ryczalt, a change of partner or share proportions, and liquidation of the business. A stocktake from the end of the previous year replaces the one for 1 January. You value it within 14 days of finishing the stocktake (§ 22(7)).
Where
The stocktake has sheets with the item number, description of the item, unit of measure, quantity, price and value (§ 21). Its value is entered in the ledger (§ 22(6)).
