Multi-State Tax Filing in LA
California Sourcing Rules
California taxes its residents on worldwide income, regardless of where it was earned. That means if you’re a California resident who worked two weeks in Georgia on a film shoot, California taxes that income too. You’ll get a credit for the taxes paid to Georgia, but it doesn’t always wash — especially when the other state’s rate is lower than California’s 13.3% top bracket.
For non-residents earning income in California, the FTB sources income based on where the work was performed. This creates filing obligations for anyone who sets foot in California for work — even briefly. If you’re based in LA and your business has clients in other states, each state has its own rules about when your presence or sales create a filing requirement.
Entertainment Industry & Location Shoots
Actors, directors, producers, and crew who film on location in other states deal with this constantly. A three-month shoot in Atlanta, a two-week reshoot in Vancouver (with U.S. tax implications), or a press tour hitting five cities in a week — each one creates a potential state tax filing. Some states have de minimis exceptions; others start counting from day one.
We track shooting schedules and work-day allocations to calculate the income attributable to each state. For union members, the allocation follows specific guild rules. For non-union freelancers, we use the duty-day method that the states themselves apply. Either way, the goal is accurate allocation so you’re not double-taxed and not under-reporting to any state that’s paying attention.
Business Nexus & Apportionment
If you run a business from LA that sells products or services to customers in other states, you need to know where you have nexus — the legal threshold that triggers a state’s right to tax your business. Since the Wayfair decision, economic nexus applies in most states based on sales volume alone, even without physical presence.
California uses a single-sales-factor apportionment formula for most businesses, meaning the percentage of your sales to California customers determines how much of your business income California taxes. Other states use different formulas — some still weight property and payroll. We model the apportionment for each state where you have a filing requirement and look for legitimate ways to reduce the overall multi-state burden.
Why Multi-State Filers Choose Us
The most expensive mistake in multi-state filing is not filing at all. States share information, and California’s FTB is aggressive about matching income reported on federal returns against what’s reported on your California return. If there’s a gap and you didn’t file in the other state, both states will eventually come asking.
We file in every state where you have an obligation, claim every credit you’re entitled to, and make sure the numbers tie across all returns. For clients who move between LA and other cities regularly, we also help with residency analysis — because where California considers you a “resident” has a bigger tax impact than most people expect.
