Fiscal subject related
Some of the most relevant changes, from a fiscalization perspective, include the use of collective correction invoices in the case of invoices in foreign currencies, changes in the use of fiscal receipt numbers,, some changes for advance payment situations, obligations in relation to fiscal reports, etc.
More precisely, fiscally relevant changes are in relation to the following:
- Applying collectively correcting invoices to foreign currency invoices: There are no regulations that indicate what conversion rates should be used for corrective invoices issued to original invoices issued in a foreign currency. With the new changes, SLIM VAT 3 adds provisions specifying which conversion rates should be used for corrective invoices issued to original invoices issued in a foreign currency. The amendment provides for the possibility of using the foreign currency exchange rate announced by the NBP on the last working day preceding the date of issuing the collective correcting invoice. For example, a taxpayer who applied the exchange rate of October 1, 2021, for the service provided, will apply the same exchange rate in the event of issuing an invoice correcting the original settlement. The taxpayer will make the conversion into PLN according to the average exchange rate of a given foreign currency announced by the National Bank of Poland on the last working day preceding the date of issuing the correcting invoice (the average ECB exchange rate will be applied accordingly) - in this case, one collective exchange rate will be used for all corrected transactions.
- Removing from the draft SLIM VAT Act 3 the modified Art. 106b sec. 1a, assuming no need to issue an advance invoice, if the taxpayer receives all or part of the advance payment, in the same settlement period in which the tax obligation arose and in relation to the activities for which the taxpayer received this payment. This change is intended to simplify the documentation obligations of taxpayers. The new provision applies to cases of receiving an advance payment in the same month in which activities related to this payment were made if the date of issuing the invoice is determined according to general rules, i.e., no later than the 15th day of the month following the month in which the activities were made (all or part of the payment from the buyer).
