The Tax Department's right to claim the tax debt is extinguished only after the passage of ten years from date of filing the tax declaration, or from the date of the expiration of the legally specified deadline for submitting the declaration, or from the date on which the Tax Department became aware of data and elements of the activities which have not been declared by the taxpayer.

The prescription is interrupted by the notification of the assessment letters, submission of an objection, a grievance, a decision by the Tax Appeals Committee, payment claim letters, or by any action taken in the enforcement process, or any act by the Tax Department towards the taxpayer that explicitly or implicitly indicates its insistence on the payment of the tax debt, or the taxpayer's acknowledgment of the tax debt, or by any tax dispute filed regarding the tax debt.

The Taxpayer's right to claim a refund of the tax amounts paid in excess is extinguished only after the passage of five years from the date on which his right to a refund arises.
