The Tax Authority can now claw back “IMT” tax breaks when owners engage in Local Lodging or letting rooms to students. If you bought your home as your “personal and principal residence”, you paid a lower property transfer tax (“IMT”) at the time of purchase. According to a recent “AT” ruling, if within the following 6 years you practice holiday or student letting, Finanças can rescind the tax break and retroactively reclaim any additional tax due.
