Private sector employers with 100 or more employees will have to file a report covering pay data and hours worked for the categories of gender, race and ethnicity. The first reports — based on 2020 pay data — must be filed with the California Department of Fair Employment and Housing by March 31, 2021, and thereafter by the same date annually. The measures feature in Senate Bill No. 973 signed by the governor on Sept. 30, 2020 and effective on Jan. 1, 2021. The bill aims to reduce the pay gap for women and people of color.
