The cases for rectifying deductions are:
Incorrect calculation of deductions.
Rectifying of taxable income due to:
- Incorrect calculation.
- Modification of the taxable base.
If the correction involves an increase in taxable income, it may be performed in the self-assessment for the period in which the taxpayer receives the corrective invoice or in subsequent returns, provided that no more than four years have elapsed since the chargeable event or the circumstances giving rise to the change in the taxable base occurred.
If the correction is not due to a change in the taxable amount, it may not be performed more than one year after the corrective invoice is issued.
If the correction involves a reduction in the taxable amount, it is mandatory and must be performed:
If it is due to a well-founded error of law or modification of the tax base: in the self-assessment for the period in which the corrective invoice was received.
In the event of bankruptcy or if the taxable transaction is rendered ineffective as a result of the exercise of a bankruptcy reinstatement action or other challenges exercised as part of bankruptcy proceedings, when the initial purchaser or acquirer is also involved in bankruptcy proceedings: in the self-assessment for the period in which the right to deduct input tax was exercised, without any surcharges or late payment interest.
If it is for another reason: shall file a corrective self-assessment, applying the appropriate surcharge and late payment interest, pursuant to Article 27 of Law 58/2003, of 17 December, on General Taxation.
