Issues obtaining an electronic copy or full enquiry
Skip information indexProblems obtaining an electronic copy in Internet Explorer
First of all, check in your browser that the toolbars you have installed (Yahoo, Google, MSN...) are not blocking pop-up elements within the Tax Agency website. If you wish, you can remove this type of blocking bars from "Control Panel", "Programs", "Programs and Features" or from "Settings", "Applications", "Applications and Features".
Also check, in your browser, that the "Enable pop-up blocker" option is unchecked, at least while you perform the full query. Go to "Tools", or the gear icon located at the top of the right corner, "Internet Options". Once there, select the "Privacy" tab and uncheck the "Enable pop-up blocker" box. If you want to only allow pop-up windows from the AEAT website, click on "Settings" and add the following address: agencytributaria.gob.es. Press "Add" and "Close".
In the "Security" tab, among the four icons in the box, check the third one, "Trusted Sites." A little further down, to the right, the "Sites" button will be enabled; Press this button and in "Add this website to the: zone" write the following: "https://*.agenciatributaria.gob.es/. The "Require server verification (https:)..." box must be checked); then press "Close". Before exiting this tab, set the "Security Level" to "Low" for Trusted Sites. Click "Apply" and then "OK."
Antivirus and firewall can also interfere with this process.
As for the rest of the requirements to be able to obtain a copy of a declaration, remember that it is necessary to have a PDF document viewer.
In "Programs and Features" in the Control Panel you can also check the installed versions. Keep in mind that normally, by default, your operating system is working with the most recent version you have installed.
