The Tax Agency of the Region of Murcia has enabled through its website the service to obtain duplicate receipts for the various taxes, including the Urban IBI (whose maximum payment date has been extended, due to the State of Alarm, until next December 30) and circulation (maximum payment date extended until October 20). Thus, from the website of the Tax Agency of the Region of Murcia (https://agenciatributaria.carm.es/web/guest//duplicadorecibos) you must access the utilities section (located on the right side) and click on duplicate receipts ; Once here, a drop-down will open in which you can select the specific receipt and thus obtain the payment letter.
