CalTax Policy Team

CalTax has the most experienced tax policy and tax-lobbying staff in Sacramento. When working on tax policy problems before the Legislature, the tax agencies, local governments, in court, or on statewide ballots, the CalTax policy team is an effective partner to CalTax members. We closely monitor legislative, tax agency, and local government tax policy deliberations, and coordinate with CalTax members and industry representatives to stop unnecessary tax policy changes that would increase the cost of doing business in California, and to support changes that would have a positive impact on CalTax members and the state economy.
