The Secretariat General for Taxation will make tax assessment on any taxpayer that is liable to furnish the return of income in accordance with the Law.

Where a taxpayer submits the final return of income, the assessment shall be made within five years from the end of the tax year in which the taxpayer submits the final return of income. If no assessment is made during the said period, the taxable income or the loss mentioned in the return of income shall be considered as an assessment.

In the case where no return of income is submitted, the assessment shall be made within ten years from the end of the tax year for which the return of income is required to be submitted. 

The Secretariat General for Taxation serves the notice of assessment on the taxpayer normally by post to its last address known to the Secretariat General. The assessment is made in writing and includes, in particular, the amount of the taxable income or the loss along with the date of assessment, the amount of the tax payable and the due date of payment.
