Shail Shah has been helping clients address California tax problems for more than 15 years. His clients range from Fortune 25 companies to high-net-worth individuals. He focuses his practice on complex California tax planning and representation in front of the California Franchise Tax Board (FTB), California Department of Taxation and Fee Administration (CDTFA), Office of Tax Appeals (OTA), Board of Equalization (BOE), and various administrative and judicial adjudicating forums at both the state and local levels. He provides advice on both proactive residency planning and residency audit defense.

Shail’s experience includes working as an attorney at the California Franchise Tax Board (FTB). He utilizes his experience to attempt to turn audits into potential refund opportunities, using tax assessments as openings to persuade state agencies that his clients may be due refunds.

Shail is an Executive Committee member of the Tax Section for the California Lawyers Association (CLA).
