The CFPB has made available a beta version of its 2018 HMDA data platform. The platform is for the reporting of data collected in 2018 that must be reported in 2019.
During the beta period, reporting institutions can test and retest 2018 HMDA data files as often as desired to assess if their Loan Application Register (LAR) data complies with the reporting requirements outlined in the Filing Instructions Guide for HMDA data collected in 2018.
No 2018 data can actually be submitted through the platform until January 2019. Based on the substantial changes to HMDA data for 2018, testing whether LAR data complies with the reporting requirements will likely be beneficial for many reporting institutions.
