Californias program that provides tax relief to film and TV productions is potentially looking at a major revamp amid an increasingly tit-for-tat race to host Hollywood.

Lawmakers, in a revised version of a bill that aims to increase the cap on the program from $330 million to $750 million a year submitted on Tuesday, propose vastly boosting the credit to 35 percent while expanding the category of productions that qualify to include shorter TV shows, animated titles and certain types of unscripted projects.

If passed, the legislation would bring the most significant changes to the program since its inception in 2009. The bill, SB 630, was spurred by a historic downturn in filming in the state caused by industry contraction and productions opting to shoot in other regions that offer more tax credits. The 20 percent base credit offered by California is lower than most competitive film hubs, including New York, Georgia and the U.K. Under the amendment, productions would get 35 percent of their spend back for costs incurred in the state. An additional five percent credit would also be available for shooting in certain areas outside Los Angeles.

And in a bid to keep up with other regions broadening the types of productions that can receive subsidies, TV shows consisting of two or more episodes of at least 20 minutes would qualify for the program, which currently only allows series with episodes of at least 40 minutes to qualify. Other productions that could get credits under the revisions to the bill include sitcoms, animated films, series or shorts and large-scale competition shows, excluding reality, documentary programming and game or talks shows. They must have budgets of at least $1 million.

Lawmakers also propose ending a requirement for a separate incentive for the construction of soundstages that the recipient owns more than half of the stages or entered into a lease of at least 10 years.

California continues to face stiff competition from other regions that are beefing up their tax relief program for the entertainment industry. Its the only major production hub that bars any portion of above-the-line costs, like salaries for actors, directors and producers from qualifying for incentives.
