CRP stands for Credit for Rent Paid. It is a Minnesota State Property Tax form residents of apartments receive each year, at the end of January, from their property manager. The form shows how much they paid in rent the prior year and what percentage of their rent qualifies for a potential Minnesota property tax refund. To qualify for the refund you have to meet certain income and residency requirements. You have until August of the following year to submit the property tax refund form (M1PR) with your CRP form.
