The Ordinance of the Minister of Finance on keeping a tax book of revenues and expenses of August 26, 2003 takes into account situations in which no external purchase document is needed. Some transactions for which an invoice is not required can be posted to the KPiR by issuing an internal voucher.

Pursuant to § 14 sec. 2 of the aforementioned regulation, the taxpayer is entitled to issue an internal ID in the following circumstances:
  • purchase, directly from a domestic producer or breeder, of plant or animal products, not processed industrially or processed industrially, if the processing involves ensiling plant products or milk processing, or for slaughter animals and post-slaughter processing of these animals;

How to correctly issue an internal ID?

The internal document is an accounting document which is the basis for the settlement in the Fiscal Register. The document must be drawn up in Polish, and its content must be understandable and complete.

Correctly issued internal evidence (DW) should contain such information as:

  • date of issue,
  • signature of the person who made the expenditure directly,
  • assigned document number.

For expenses, the person making the purchase should specify the name of the goods and the quantity, unit price and value. In other cases, the amount of the cost should be specified.
