VAT: Reverse charge mechanism for civil construction services in Portugal
This article explains the reverse charge mechanism applicable to civil construction services in Portugal. It analyzes when it applies, the requirements for the purchaser to “self-assess” the tax, and the practical consequences for those who provide construction services and those who purchase them.
1. What is the reverse charge mechanism for VAT?
The reverse charge mechanism is a rule whereby, in a transaction subject to VAT, the purchaser (customer) — and not the supplier — is liable for paying the tax.
In Portugal, this rule applies to certain civil construction services when the purchaser is a VAT taxpayer who carries out an activity that entitles them to a full or partial deduction of the tax.
In other words, if someone provides civil construction services (repairs, renovations, maintenance, demolition, coatings, painting, etc.), and the customer is an entity that can deduct VAT, the customer will have to pay the tax themselves, rather than the service provider.
It is also important that the services are considered “construction services” according to the legal definition — the concept includes construction, reconstruction, alteration, repair, maintenance, rehabilitation, and demolition works, as well as installation and assembly works related to the property.
2. Conditions for applying the reverse charge mechanism
For the rule to apply, two cumulative conditions must be met:
1. Acquisition of civil construction services by the purchaser;
2. The purchaser must be subject to VAT in Portugal, carrying out transactions that entitle them to deduct the tax (in full or in part).
If these conditions are met, the supplier must not charge VAT on the invoice. Instead, the invoice must contain the indication “VAT – Self-assessment,” in accordance with Article 36(13) of the VAT Code.
There are some exceptions or limitations:
• The mere delivery of goods without installation or assembly is not included in the reverse charge rule.
• When goods are delivered with assembly or installation, as part of construction work, the reverse charge rule applies, provided that the goods are part of the construction work.
• Movable goods that are not physically attached to the property, or that are clearly separate movable goods, are excluded from the reverse charge.
3. Practical impacts for service providers and purchasers
For service providers:
• You must be aware of the obligation not to charge VAT in certain cases, using the expression “VAT – Self-assessment.”
• They must report the amount invoiced under this rule in the appropriate section of the periodic VAT return (section 06, field 8).
For purchasers of civil construction services:
• They will self-assess the tax, i.e., they will assume the VAT settlement on the service received.
• When completing the periodic VAT return, the purchaser must enter the taxable base (field 1, 5, or 3, as applicable) in table 06 and the tax due in field 102 of table 06-A.
• If eligible, you may deduct this VAT as input tax if you meet the legal requirements for deduction.
The correct application of this rule requires rigorous documentation and adequate internal control to avoid non-compliance or tax errors.
4. Examples and practical cases
Let’s imagine that a painting company provides coating and decoration services in a building to another company that is subject to VAT with the right to deduction.
In this case, the contracting company will be the one to self-assess the VAT, not the painter.
If that same painting company only sells materials without assembly or installation, the rule does not apply in that specific part, and normal VAT could be charged.
Another scenario: if a public entity (not a taxable person with the right to deduction) hires a construction company, the reversal may not apply, depending on the conditions for VAT deduction.

Conclusion
VAT reverse charge is a relevant rule for the construction sector in Portugal. When the legal conditions apply—construction services purchased by taxable persons who are entitled to deduction—the purchaser assumes the settlement of the tax, with important implications for both parties.
It is essential that providers and purchasers correctly understand the requirements, procedures, and exceptions, and that they adopt rigorous tax practices.
