Copy of tax return filed on paper or other by another means other than online
If you submitted your return on paper and cannot obtain a copy through the Tax Agency website, you can contact the corresponding Administration or Delegation to see if they can provide you with a copy of your return. The addresses and telephone numbers of all Administrations and Delegations are published on the website, in the "Contact us" section located at the bottom of the page.
If it is an Income Tax return, you can request a tax certification from Personal Income Tax that contains all the Income charges that are reported to the Tax Agency in a specific year.
