Portugal's housing crunch has become one of the country's defining political battles, and the Socialist opposition has just put a fresh set of proposals on the table. In an open letter to Prime Minister Luís Montenegro published in Público on 19 October, party leader José Luís Carneiro laid out a three-year tax package designed to push hundreds of thousands of empty, habitable properties back onto the sales and rental markets.
The headline measure: capital gains tax exemptions on sales of existing homes worth up to €300,000, as long as buyers intend to live there permanently. Sales between €300,000 and €500,000 would get a reduced rate instead. Stamp duty would also be waived for qualifying purchases and their mortgages. For landlords, there's a carrot too – an optional five-year rental contract with rental income taxed at just 5%, backed by a public guarantee against unpaid rent.
Beyond the tax breaks, Carneiro wants a state-run rental guarantee scheme folded into the 2027 State Budget. The idea is that the government would compensate landlords for missed rent or property damage, then chase the tenant for repayment. It would be voluntary and cover renters aged 18 to 35 plus households meeting income criteria, provided contracts are registered with the tax authorities and rents stay within affordable limits. He's also calling for the rent deduction in annual income tax returns to rise to €1,000 from 2027, and for an overhaul of the public tenant-landlord dispute service, the Balcão do Arrendatário e do Senhorio, which he says isn't working.
Longer term, the Socialists are promoting a National Affordable Housing Service (SENHA), a ten-year programme pulling together municipalities, cooperatives, associations and private developers to expand affordable supply, currently being shaped through a national consultation.
The political context matters. Protests over housing costs have hit several Portuguese cities, and Carneiro accuses the government of stalling – this is his second letter to Montenegro after an August one he says went unanswered. The measures land as parliament gears up to debate the 2027 budget, though housing isn't among the Socialists' four conditions for letting it pass. For now these are opposition ideas, and nothing becomes law without legislative approval.
Why should travellers care? Anyone who has priced Lisbon or Porto rentals lately knows Portugal's housing squeeze hits visitors as well as locals, with short-term let restrictions and rising costs partly a response to the shortage. And for the many foreigners weighing a move or a permanent base in Portugal, the proposed €300,000 capital gains exemption could meaningfully change the maths of selling a property – while the low-tax landlord scheme might tempt owners of second homes into long-term renting instead. None of it is confirmed policy yet, so treat it as a signpost of where the debate is heading rather than a done deal. For updates, Portugal Resident has the full story.
