Article 63 of the Decree-Law specifies the procedure for tax adjustments when a Registrant issues a Tax Credit Note. This action is taken to correct the Output Tax initially charged to a recipient of goods or services. The article stipulates a dual effect: for the Registrant issuing the note, the tax amount specified is treated as a reduction of their Output Tax. For the Recipient of Goods or Services, the same amount is considered a reduction of their recoverable Input Tax. This reduction for the recipient must be accounted for in the tax period during which the Tax Credit Note was received.

Chapter 4 - Adjustment of Tax after the Supply Date

Article 63
Adjustment due to the Issuance of Tax Credit Notes

Without prejudice to Clause 2 of Article 62 of this Decree-Law, if the Registrant issues a Tax Credit Note to correct Output Tax charged to the Recipient of Goods or Recipient of Services, the Tax stated in the Tax Credit Note shall be considered as:

A reduction of the Output Tax for the Registrant of this Tax Credit Note.
A reduction of the Input Tax by the Recipient of Goods or Recipient of Services for the Tax Period during which the Tax Credit Note was received.
