In 2004, Jackelyn Navarro decided that after many years of working in tax preparation she would like to have her own business. Hence, soon after she opened the doors to San Mateo Tax Service, and in 2006 we had our ground opening ceremony at our new location 521 E. 3rd Avenue, San Mateo, CA. We are a professional tax preparation team and are able to serve our clients who speak English and Spanish.
