What is a VAT reduction certificate BTP?

The reduced VAT certificate is the document signed by the customer (owner or tenant) certifying that the conditions for applying the reduced rate are met.

Article 279-0a extends this scheme to the 5.5% rate for eligible energy renovation works. The certificate must mention: the customer's lodging, the nature of the identity (>2 years), the address and amount of the work, the commitment to honour. The contractor must keep the commitment to advance during 10 years (duration of the tax exemption) the simplified electronic signature the Certitia.

Frequently Asked Questions

Can a reduced VAT certificate be signed electronically?
Yes the tax doctrine (BOI-VAT-LIQ-30-20-90-30) expressly allows for advanced electronic signature for reduced VAT certificates, provided that the trail audit allows verification of the identity of the signatory and the integrity of the document.
When is the certificate to be signed?
The tax doctrine allows the signature until the invoice date after which the administration may refuse to grant the reduced rate.
What are the conditions for benefiting from 10% VAT (Article 279-0a of the General Tax Code)?
Housing for residential use (main or secondary residence) completed more than 2 years ago, improvement/transformation/development/maintenance works.
What are the conditions for the 5.5% VAT (energy renewal)?
The same conditions as for 10% (housing > 2 years) PLUS energy renovation works: thermal insulation (opaque walls, windows, roof), installation/maintenance of eligible materials and equipment (high-performance heating: heat pumps, biomass boiler, ENR: solar thermal/photovoltaic, ventilation).
How do you prove the house is more than two years old?
The certificate of ownership, the property tax for the year concerned, the certificate of completion of the work or the certificate of honour of the client.
How long must the certificate be kept?
10 years (Art. L102 B Book of tax procedures). Mandatory storage for the contractor AND the customer. Certyneo automatically archives the two copies during this period accessible to both parties in case of control.
What happens if you get a false statement?
The certificate is a declaration of honour for the client. If it turns out to be false (housing < 2 years, field work), the client is jointly responsible for the additional VAT due with the contractor (Art. 279-0 bis 5 ° CGI).
Is the electronically signed certificate enforceable by the tax authorities?
Yes administrative case law recognises eIDAS-compliant electronic signature. The Certyneo audit trail (OTP identity, qualified timestamp, SHA-256 hash) proves the identity of the signer, the date of signature and the integrity of the document appealable to the tax administration and the administrative court.
