Spain rental market hit by tourism‑driven cost rise and tax crackdown

A study commissioned by Transport & Environment estimates that air‑tourism growth will add an average €217 (about €18 per month) to Spanish renters’ annual costs by 2031, a 1.6 % extra increase on top of normal rent rises. The impact is strongest in the Balearic Islands, Canary Islands and Barcelona, where tourist arrivals are highest.

At the same time, Spain’s tax agency has uncovered €22.743 billion in previously hidden rental income, increasing inspections by 2.9 % to 1.9 million checks. Authorities are targeting undeclared holiday rentals, fake invoices and simulated tax residency, with penalties reaching up to 150 % of the evaded amount. The agency urges property owners to regularise their tax affairs and notes that the new Verifactu invoicing system will further tighten oversight.
