Racehorses

Racehorses are subject to an in-lieu tax as defined in Section 5701 through 5720.5 of the California Revenue and Taxation Code. Since 1973 this tax has been imposed for the privilege of breeding, training, and caring for or racing a racehorse domiciled in the State of California.

If you own racehorses, each year you should receive an Annual Racehorse Tax Return, Form 571-J. You are required to complete this form by providing detailed characteristics and earnings for each racehorse you own. Instructions for completing the form are provided. Please note you are required to compute your own tax liability and submit the form and taxes by February 15 to the Alameda County Treasurer- Tax Collector, 1221 Oak St., Room 131, Oakland, Ca, 94612, or penalties will result.

If you own property on which boarded horses are kept, you must file the “Annual Report of Boarded Racehorses” Form 571-J1. This form must be filed with the Assessor by January 10. Please mail this form to the Alameda County Assessor, 1221 Oak St., Room 145, Oakland, CA 94612.
