HOW THE CRIM CONTRIBUCIÓN WORKS
In Puerto Rico the property tax (contribución sobre la propiedad inmueble), collected by CRIM, is charged on a property's assessed value pegged to 1957 replacement cost — the last island-wide scientific reassessment — not its market price, so the assessed value is usually a small fraction of what the property sells for. The total rate combines a basic municipal contribution and a 1.03% state contribution, and it varies by municipality (residential totals commonly run about 8.03%–8.33%, commercial higher). An owner-occupied primary residence is exempt on the first $15,000 of assessed value. The bill is paid semi-annually, on July 1 and January 1. Two cautions for investors: CRIM debt attaches to the parcel (you can inherit unpaid back taxes), and this is an estimate — pull the certificación de deuda for the exact assessed value, balance, and your municipality's rate before you bid.
