Portuguese property owners with annual property tax (IMI) exceeding 500 euros are required to pay the second installment today. The payment is made directly to the Portuguese Tax and Customs Authority (Finanças). This deadline applies to all property owners whose annual IMI assessment falls above the specified threshold. Failure to meet the deadline may result in penalties and interest charges. The IMI is an important source of revenue for local municipalities in Portugal. Property owners are encouraged to verify their payment status and ensure timely remittance to avoid complications. This second installment is a crucial part of the annual property tax obligations.
