FAQs

A certification or tax certificate is the document issued by the Tax Administration that certifies facts related to the tax situation of a liable taxpayer.

Tax certificates can accredit, among other things, the submission of tax returns and self-assessments and the communication of data or of specific details contained in them, census status, whether tax obligations are up-to-date and the existence or absence of unpaid debts or fines that appear in the databases of the Administration of the Tax Agency.

The facts or data to be certified will refer exclusively to the liable taxpayer who the tax certificate refers to. The certificate shall not include nor refer to any details relative to third parties.

No data related to tax debts shall be certified for which the right of the Administration may have prescribed to determine the payable tax through the appropriate settlement.

No certificate will be issued either on the fulfilment of tax debts for as long as the voluntary deadline for its fulfilment has not prescribed.

Tax certificates will contain, at least, the following data and circumstances:

• Name and surnames or trade name or complete denomination, tax identification code and tax address of the liable taxpayer.
• The circumstances, obligations or requirements that must be certified.
• The nonexistence of the information that is requested on the data bases of the Tax Administration or the inappropriateness of supplying this information, when this can not be certified.
• Place, date and signature of the competent organ for its issue and the safe verification code. 

As a general rule, when the certificate being sought is whether one is up-to-date with one's tax duties, or one of contractors and subcontractors, the result of the tax certificates will be one of the following:

• Positive if it is determined that tax obligations are up-to-date.
• The certificate is denied due to debts held by the applicant.
• The certificate is denied due to the applicant failing to submit tax returns.
• The certificate is denied due to the two previous reasons.

The content, authenticity and validity of the tax certificate can be verified through the "Notifications and Verification of documents" service located on the homepage of the Tax Agency's E-Office, entering the CSV in the section "Document check with CSV."

Use the Secure Verification Code (CSV) that appears in the certificate.

The copies of the certificates will have the same validity and will have the same effects as the certificates themselves, as their content, authenticity and validity can be checked by means of the Secure Verification Code (CSV).
