6% VAT on Construction: The Essential Guide for Owners and Investors

Few tax measures have caused as much confusion in recent months as the so-called "6% VAT on housing". Messages are circulating claiming that "buying a home now carries 6% VAT", that "all works have become cheaper" or that "you just have to claim a refund of the difference". Most of these statements are wrong or incomplete. This article explains, in a simple but rigorous way, what was actually approved, what is already in force and — just as importantly — what continues to be taxed at the standard rate of 23%.

Is the 6% VAT on housing already in force?

During 2025 and early 2026 it was, in fact, only an announcement and then a legislative authorisation. That phase is now over. Today there is approved legislation, published in the Diário da República and supplemented by operational instructions from the Autoridade Tributária (Portuguese Tax Authority). That is why the answer has changed from "it is still a proposal" to "it is already in force, with precise rules".

What was actually approved

The measure rests on three documents, which it is worth distinguishing:

• Lei n.º 9-A/2026, of 6 March — the legislative authorisation that empowered the Government to create the reduced rate. On its own, this law did not yet lower VAT; it paved the way for the instrument that would do so.
• Decreto-Lei n.º 97/2026, of 20 May — the instrument that gives effect to the measure, incorporating housing works into the list of goods and services subject to the reduced rate and defining requirements, limits and obligations.
• Ofício Circulado n.º 25116, of 23 June 2026, from the Autoridade Tributária — the practical instructions for invoicing and adjustments, which set the effective date at 1 July 2026.

In other words: what is already in force is the application of the 6% rate to eligible works since 1 July 2026. What depends on a procedure is the refund mechanism for those who built their own home and for invoices issued in the first months of 2026 (see below). There are no "interpretations" to invent here: the rules are written down.

Who the 6% rate applies to

The reduced rate directly benefits whoever contracts the works — usually the developer, the builder or the owner who commissions the work — and, indirectly, whoever buys or rents the final property, insofar as the construction cost falls. Specifically, the following may benefit:

• Developers and construction companies that build or renovate housing intended for sale as an own and permanent home, or for residential letting, within the price limits.
• Investors and landlords who build or renovate to place the property on the residential rental market, respecting the rent limits and the deadlines.
• Private owners who renovate their home through an eligible works contract.
• Self-builders — individuals who build their own home outside of business activity — through a specific mechanism for the refund of the tax difference.

One essential point: a formal works contract is always required. Having a builder's quote and approving it verbally is not enough.

Which properties and works can benefit

The 6% rate applies to construction and renovation works on properties intended for housing, when the urban development operation is initiated between 25 September 2025 and 31 December 2029. The tax must become chargeable from 1 January 2026 and up to 31 December 2032.

In principle, the following are covered:

• Construction of new housing intended for an own and permanent home or for residential letting;
• Renovation works on properties for the same purposes;
• Movable goods and equipment that become materially attached to the property on a permanent basis and are invoiced within the works contract.

Main requirements and limits

The reduced rate is not automatic: it depends on meeting several requirements. The main ones are:

• Value limit on the sale: the price of the property cannot exceed 660 982 euros (the amount corresponding to the upper limit of the 2nd IMT bracket for 2026).
• Rent limit on letting: the monthly rent cannot exceed 2 300 euros.
• A formalised works contract is indispensable.
• Deadlines: on a sale, the property must be transferred within a maximum of 24 months after the licence/use permit; on a letting, the first contract must begin within 24 months of the use permit and the property must remain let for at least 36 months (consecutive or not) in the first five years.
• Housing purpose: the operation must serve an own and permanent home or residential letting — not tourist, commercial or speculative investment purposes.
• Self-build: those who build their own home pay VAT to the builder at the standard rate and then apply for a refund of the difference from the Autoridade Tributária, provided the property does not exceed 660 982 euros, becomes an own and permanent home within 6 months of the use permit and remains so for at least 12 months. The application is electronic, within 12 months of the use permit, and the refund is paid within a maximum of 150 days. Applications relating to the first three quarters of 2026 are only accepted from 1 October 2026.

Situations that are not covered

Just as important as knowing what benefits is knowing what stays at 23%. The following do not benefit from the 6% rate:

• The purchase of the home itself — the transfer of the property does not acquire "6% VAT" (see the next section);
• Properties above the limits in value (over 660 982 euros in price or 2 300 euros in rent);
• Local accommodation and other tourist purposes;
• Second homes and properties not intended for an own permanent home or for residential letting within the limits;
• Commercial, industrial or service properties;
• Construction materials bought separately by an individual (without a works contract);
• Standalone architecture, engineering and supervision services invoiced separately from the works contract;
• Maintenance work on green spaces, swimming pools and sports grounds.

6% VAT on construction versus buying a home

This is the biggest source of misunderstandings, so it is worth being clear. In Portugal, the purchase of housing is not, as a rule, subject to VAT — it is subject to IMT and Stamp Duty. When you buy a home from a developer, you do not pay "23% VAT" nor do you start paying "6% VAT" on the price.

What the measure does is reduce from 23% to 6% the VAT that the builder charges for the works to the developer or the owner of the project. It is a tax that falls on the construction or renovation service, not on the deed of purchase. The benefit to the buyer is indirect: if building costs less, the final price of the home can be more competitive — but that depends on the developer passing the saving on in the price, which the law does not require.

Practical examples

Let us imagine a renovation works contract of 100 000 euros (the value of the works, before tax), on an eligible home:

The potential saving is 17 000 euros (17 percentage points). But beware: this saving only exists if all the legal requirements are met — a valid works contract, a property within the value limits, a housing purpose and deadlines respected. If any condition fails, the 23% rate applies and there may also be corrections and penalties.

Myths and truths

What buyers, owners and developers should do before proceeding

• Confirm the eligibility of the property (purpose, value, deadlines) before signing anything.
• Always formalise a works contract — it is a legal condition, not a formality.
• Request correct invoicing from the builder, stating the treatment and the rate applied.
• Keep all documentation (licences, contract, invoices), especially in the case of self-build, to support the refund application.
• Verify deadlines and holding obligations (24 months for a sale, 36 months of letting, own permanent home) so as not to lose the benefit or incur an IMT surcharge.
• Consult a certified accountant, lawyer or tax adviser before deciding — each case has its own specifics.

Conclusion

The 6% VAT on housing is a real measure, approved and in force since 1 July 2026 — but more limited than many messages suggest. It reduces the tax on construction and renovation works on moderately priced housing intended for an own permanent home or residential letting, and it requires compliance with precise conditions. It is not a discount on the purchase of the home, it does not cover all works and it does not apply to tourist or luxury purposes. Used well, it can represent a significant saving; poorly framed, it can trigger corrections and penalties. Getting informed before proceeding is the most profitable step.
