Portugal: New VAT relief, old urban rehabilitation worries

Portugal’s latest housing tax package sends a clear policy message: tax policy is being deployed to tackle the country’s housing shortage. The centrepiece is a temporary 6% VAT rate for qualifying construction and rehabilitation contracts relating to residential property – whether intended for sale to owner-occupiers (up to approximately €661,000) or for residential letting (rent of up to €2,300 per month).

The reduced rate applies to the construction and refurbishment of residential properties for which VAT becomes due between July 1 2026 and December 31 2032, provided the underlying planning procedure was initiated between September 2025 and December 2029. The package also introduces partial VAT refunds for individuals building their own homes, reduces the taxation of rental income, creates long-term investment contracts for affordable rental housing, and improves the taxation of real estate funds dedicated to residential leasing.

These measures are forward-looking, but resolving the housing crisis also requires addressing legacy uncertainty stemming from the prior VAT regime. The Portuguese parliament is discussing a measure intended to clarify how one such rule should be interpreted: the provision that established a reduced VAT rate for urban rehabilitation works, which was in force before October 2023. Under that rule, the reduced rate applied to urban rehabilitation carried out on properties located within a legally delimited Urban Rehabilitation Area (Área de Reabilitação Urbana, or ARU), formally designated by a municipality as requiring urban rehabilitation.

Under Portugal’s urban rehabilitation framework, a municipality may delimit an ARU without simultaneously approving a corresponding Urban Rehabilitation Operation (Operação de Reabilitação Urbana, or ORU).

For many years, real estate developers and construction companies understood that rehabilitation works in a legally delimited ARU qualified for the former reduced VAT regime. Municipalities frequently created ARUs to encourage investment in older urban areas, and ARU status was widely relied upon when projects were priced, structured, and invoiced.

The tax authorities subsequently adopted a more restrictive approach, arguing that the reduced rate required not only the approval of the ARU by the municipality but also a previously approved ORU. The Supreme Administrative Court endorsed that interpretation in a case-law uniformisation judgment (acórdão de uniformização de jurisprudência), a ruling with binding effect on future case law. The consequences were potentially substantial: contractors and developers involved in completed projects faced additional VAT assessments at the standard rate, even where works had been priced and invoiced – and, in some cases, the resulting properties sold – on the understanding that ARU status alone was sufficient.

In 2026, the Constitutional Court examined the constitutionality of an evidence requirement related to municipal certification that rehabilitation works were carried out on a property located in an ARU with an approved ORU and found no breach of fundamental principles. Crucially, however, it did not revisit the underlying statutory question: whether the former reduced-rate provision itself required an approved ORU in addition to a legally delimited ARU. That question – which had divided taxpayers, the tax authorities, and academics – remained open.

Against this background, the party supporting the government presented a bill in the Portuguese parliament to address the legacy uncertainty (Projeto de Lei 642/XVII/1). The bill does not create or extend the new 6% VAT regime. It concerns the historical urban-rehabilitation VAT provision in force before October 2023, and its proposed solution is clear: a legally delimited ARU should be sufficient for reduced-rate treatment, independently of whether the municipality had also approved an ORU. In effect, the bill rejects the restrictive interpretation endorsed by the Supreme Administrative Court.

The proposal was unanimously approved at first reading on July 3 2026, though it must still undergo committee-stage scrutiny and a final vote. If enacted, it would operate as an authentic interpretative law under Portuguese civil law doctrine, applying retroactively to 2008 as though it had always formed part of the interpreted provision. This would mean that parliament would be declaring how the former provision should have been understood from the outset. This could affect taxpayers facing historical assessments, pending litigation or unresolved repayment claims, although limitation periods, procedural mechanisms, and the fiscal cost of retrospective relief would all require separate analysis.

Portugal’s new housing VAT regime is designed to encourage future supply. The separate parliamentary initiative addresses a different but connected concern: restoring confidence in an earlier incentive that many market participants considered available.

Together, the two developments underline a broader point. The effectiveness of a tax incentive depends not only on its rate and eligibility conditions but also on the confidence that taxpayers can place in its interpretation over time. Portugal has gained new VAT relief. Whether it can also put its old urban rehabilitation worries behind it will depend on the outcome of this bill – and on the practical implementation of any legislative clarification that follows.
