Frequently Asked Questions

Do I need to register and file California sales tax if I sell online?
It depends on where you’re based, where inventory sits, and how you sell. Quick checklist:
- List your sales channels (Shopify, Amazon) and any sales tax filing services used
- Note where products ship from or are stored
- Pull sales totals and order counts for the period
How do marketplace sales affect what I file in California?
Many marketplaces collect and remit tax on some CA sales, but direct-site sales can still create filing requirements.

RJM Tax Exemption helps sort out what’s marketplace-collected versus what’s on you, so filings stay clean.
Can RJM do ecommerce sales tax filing in CA for single-member LLCs?
RJM Tax Exemption does file CA taxes for ecommerce single-member entities. Not sure if that’s you? Ask, clearing up business-type early saves time.
