-
Are services taxable in California?
Most services are not taxable, but some bundled or fabrication-related services can be. We review your specific offerings and invoices to confirm treatment.
-
How do I know if I have sales tax nexus in California?
Physical presence (office, inventory, employees) creates nexus. So can economic thresholds or marketplace activity. We run a nexus analysis across states where you sell.
-
How often will I file with CDTFA?
The state assigns monthly, quarterly, or annual filings based on volume. We confirm your cadence and build a calendar with internal reminders.
-
What’s the difference between sales tax and use tax?
Sales tax applies to taxable sales you make; use tax applies when you buy taxable items without paying sales tax (e.g., out-of-state vendors). We’ll help you calculate and report both.
-
How do marketplace facilitator rules affect me?
Marketplaces often collect and remit on your marketplace sales, but you’re still responsible for own-site sales and accurate registrations. We prevent double-collection and keep registrations clean.
