Tax Compliance Certificate

A tax compliance certificate confirms that a supplier is current with its tax obligations. In the context of European public procurement, it is the standard documentary response to the discretionary exclusion ground in Article 57(4)(b) of Directive 2014/24/EU: that the supplier "has not fulfilled obligations relating to the payment of taxes." Alongside the social security compliance certificate, it is one of the two compliance certificates most commonly requested by contracting authorities across Europe.

What is a tax compliance certificate?

A tax compliance certificate (also called a tax clearance certificate, certificate of tax compliance, fiscal regularisation certificate, or similar, depending on the jurisdiction) is issued by the national tax authority and confirms that no undisputed tax debts are outstanding against the applicant. The certificate typically covers direct taxes (corporate income tax, income tax for sole traders) and indirect taxes (VAT). Some member states issue separate certificates for different tax types; others issue a single combined certificate.

Discretionary ground. Article 57(4)(b) of Directive 2014/24/EU makes non-payment of taxes a discretionary exclusion ground, meaning contracting authorities may choose to activate it but are not required to. In practice, the vast majority of contracting authorities in Europe activate this ground for all above-threshold procedures, making the tax compliance certificate effectively universal.

Self-declaration and verification. In the ESPD Response, the supplier declares whether any tax obligations are unfulfilled. At the award stage, the contracting authority requests the certificate as means of proof. The eCertis database identifies the national equivalent certificate for each EU member state.

Validity periods. Tax compliance certificates have short validity windows in most jurisdictions. Ireland's tax clearance certificate (issued electronically by the Revenue Commissioners) is valid for one year. In France, the attestation de regularite fiscale is valid for six months. In Italy, the Documento Unico di Regolarita Contributiva (DURC) covers both tax and social security with a 120-day validity. Always check the procurement documents for the maximum age the contracting authority will accept.

Dispute exceptions. The exclusion ground applies to taxes "established by final decision." If a tax liability is genuinely disputed and the subject of ongoing proceedings, it may not constitute an activating ground. The key word is "undisputed." Suppliers with disputed tax positions should take legal advice on whether and how to disclose the dispute in their ESPD Response.

Why tax compliance certificates matter for bidders

Tax compliance certificates are time-sensitive and sometimes slow to obtain. Some member states issue them within days through online portals; others require a formal written application with a processing time of several weeks. A supplier competing frequently across Europe should maintain awareness of the certificate status in each relevant jurisdiction.

For companies with subsidiaries, associated companies, or branches in multiple countries, the procurement documents may require tax compliance evidence for each entity that is part of the bid.

Example

A Dutch logistics company bids for a Belgian public procurement framework. The Belgian authority activates the tax non-compliance discretionary ground in its ESPD Request. The Dutch company declares in its ESPD Response that no tax non-compliance ground applies. Upon being ranked first, the Belgian authority requests the certificate. The Dutch company obtains a verklaring betalingsgedrag belastingdienst from the Belastingdienst (Dutch Tax Authority) and submits it within the requested fifteen working days.

Frequently Asked Questions

What if my company has a payment plan with the tax authority for historical debts?

A formal instalment agreement approved by the tax authority is generally treated as evidence of regularisation. Many tax authorities will issue a compliance certificate where the taxpayer is complying with an agreed payment schedule. Include details of the arrangement in your ESPD Response and obtain written confirmation from the tax authority that you are in good standing under the agreement.

Do I need a tax compliance certificate from every country where I operate?

Typically, the contracting authority requires a certificate from the country where the legal entity is incorporated and registered for tax. If you have a branch or permanent establishment in another country with its own tax registration, you may also be required to provide a certificate for that jurisdiction. Clarify this with the contracting authority if your tax footprint is complex.

How do I obtain a tax compliance certificate if my country has no online system?

Most EU member states now offer online applications, but processing times vary. If you are bidding cross-border and are unfamiliar with a foreign country's tax authority process, professional advisers (accountants or local lawyers) can assist with obtaining local certificates on your behalf.
