The state of California recently expanded its tax credit program for film and TV productions, according to the Wall Street Journal:

The new legislation, which more than triples the state’s current program to an annual $330 million in incentives over five years, was signed by Democratic Gov. Jerry Brown last month and goes into effect in 2015. Part of that annual allotment will go toward tax credits for visual-effects work, now covering 25% of eligible expenditures in the field, up from 20% under the old program.

In California, films that cost over $75 million, basically every VFX-driven Hollywood film, were previously ineligible for the state’s tax incentive program, but beginning next year, the law will accommodate films of any budget. However, the tax credit will be applicable to only the first $100 million of any production’s budget.

According to some studies, tax breaks for movie studios have proven economically ineffective in states like Louisiana, North Carolina, and Massachusetts. “Our economists tell us it’s the worst return on investment of any of the tax-credit programs,” North Carolina politican Paul “Skip” Stam told the LA Times. That same Times pieces suggests that even within California, some government officials claim that the film tax credits generate a negative return on investment.
