How does California sales tax work and what are my CDTFA filing requirements?
Before you sell anything taxable in California, you need a seller’s permit from the California Department of Tax and Fee Administration (CDTFA). This is free and required. Operating without one is illegal and can result in penalties, back taxes, and interest. You can apply online through the CDTFA website.
California’s sales tax starts with a statewide base rate of 7.25%. On top of that, cities and counties add district taxes that vary by location. In parts of Orange County, your total combined rate can land somewhere between 7.75% and 10.25% depending on the exact address where the sale happens. The CDTFA provides a rate lookup tool so you can find the precise rate for your business location. If you ship products to customers in other parts of California, you may need to charge the rate for the delivery destination, not your storefront.
Most tangible goods are taxable. If a customer can touch it and take it home, you’re probably charging sales tax on it. Groceries (unprepared food) are generally exempt, but prepared food sold at restaurants is taxable. Clothing is taxable in California, unlike some other states. Most services are not taxable, though there are exceptions. If your business sells a mix of products and services, you need to understand which portions are taxable and charge accordingly.
The CDTFA assigns your filing frequency based on how much tax you collect. Most small businesses file quarterly, with returns due on the last day of the month following the quarter’s end. So Q1 (January through March) is due April 30. If you’re collecting $10,000 or more per quarter in sales tax, the CDTFA will move you to monthly filing. Some very small sellers may qualify for annual filing. Your specific frequency will be stated on your seller’s permit or in your CDTFA online account.
Pay attention to due dates because penalties start immediately. Filing late triggers a 10% penalty on the amount owed. Interest accrues on top of that. Even if you can’t pay the full amount, file on time and pay what you can to minimize what you owe in penalties.
Keep documentation for any sales where you didn’t collect tax. If a customer presents a resale certificate because they’re buying inventory for their own store, you need that certificate on file. Without it, the CDTFA can hold you responsible for the uncollected tax during an audit. The same applies to other exempt sales. Document everything.
Tracking all of this gets complicated fast, especially if you sell across multiple channels or locations. Working with bookkeepers in Buena Park who understand California sales tax means your rates stay current, your returns get filed on time, and your exempt sale records are organized if the CDTFA ever comes asking. Our sales tax management service handles the calculation, filing, and rate tracking so you can focus on running your business instead of worrying about compliance deadlines.

Medical devices and clinical equipment are capitalized as fixed assets and depreciated over their useful life rather than expensed in one year.

Proper tracking with serial numbers and a fixed asset register is essential for audits and insurance.
