If your business sells tangible goods in California, 2026 compliance still comes down to three things: where you have nexus, what rate applies, and how often you must file. California’s statewide base rate remains 7.25%, but the CDTFA’s current city and county rate tables are effective April 1, 2026, and district taxes can materially change the amount you owe depending on the delivery address. California sales tax generally applies to retail sales of goods and merchandise, while services are generally outside the tax unless they are part of the sale of tangible personal property.

Key Takeaways for 2026
| Topic | 2026 rule | Why it matters |
|---|---|---|
| Statewide base rate | 7.25% | This is the starting point before district taxes are added. (cdtfa.ca.gov) |
| Economic nexus | $500,000 in combined sales into California | Remote sellers must register once they exceed the threshold. (cdtfa.ca.gov) |
| Marketplace sales | Count toward the $500,000 threshold | Marketplace sales are included when determining nexus. (cdtfa.ca.gov) |
| Bad debt deductions | Lenders and affiliated entities are restricted for write-offs on or after Jan. 1, 2025 | Retailers can still qualify, but financing structures changed. (cdtfa.ca.gov) |
| Unremitted tax penalty | 40% penalty, with a $1,500/month or 25% exception | Knowingly collected tax must be remitted on time. (cdtfa.ca.gov) |
| Firearm/ammunition excise tax | 11% | Applies to covered firearm and ammunition retail sales. (cdtfa.ca.gov) |
| Quarterly prepay trigger | Average liability of $17,000+ per month | Some accounts must prepay 90% of their liability. (cdtfa.ca.gov) |
| EFT threshold | Average monthly liability of $10,000+ | High-liability accounts must pay electronically. (cdtfa.ca.gov) |
1. California Economic Nexus in 2026
California’s remote-seller rule is still one of the most important compliance tests in the state. Under CDTFA guidance, a remote seller must register for a seller’s permit or a certificate of registration-use tax if, during the preceding or current calendar year, the seller’s total combined sales of tangible personal property for delivery into California exceed $500,000. That rule applies to sales into California by the seller and related persons. (cdtfa.ca.gov)
A key point for 2026: marketplace sales count toward the $500,000 threshold. At the same time, if all of a marketplace seller’s sales in California are marketplace sales, CDTFA states that the seller is generally not required to register solely for those sales. If the seller also makes direct sales, those marketplace sales still count when determining whether the seller is engaged in business in California. (cdtfa.ca.gov)
What this means in practice
If your business is a remote seller with:
- direct sales into California,
- marketplace sales into California, or
- both,
you should track total California sales carefully. If you cross $500,000, you are in the California registration and collection system. (cdtfa.ca.gov)
2. California Sales Tax Rate and District Taxes in 2026
The statewide base rate is still 7.25%, but that is not the whole story. California’s total rate depends on the specific city, county, or district where the sale is delivered or otherwise sourced under the applicable rules. CDTFA’s rate pages are updated for April 1, 2026, so the only safe way to confirm the correct rate is to use the current CDTFA address lookup or city/county rate table before you invoice the customer. (cdtfa.ca.gov)
Rate structure at a glance
| Component | 2026 rule | Notes |
|---|---|---|
| Statewide base rate | 7.25% | Made up of state and local components. (cdtfa.ca.gov) |
| District taxes | Vary by location | District taxes can increase the total rate above 7.25%. (cdtfa.ca.gov) |
| Rate lookup | Use the CDTFA current rate table | CDTFA’s current city/county rate page is effective April 1, 2026. (cdtfa.ca.gov) |
Why this matters for online sellers
If you sell into multiple California locations, your tax engine should not rely on a single state rate. A sale delivered to one ZIP code may be taxed differently than an identical sale delivered a few miles away. That is why the CDTFA rate lookup by address is essential for 2026 compliance. (cdtfa.ca.gov)
3. Legislative Updates That Matter in 2026
Bad Debt Deductions After SB 167
California’s bad-debt rules changed for lenders and affiliated entities beginning January 1, 2025. Under CDTFA guidance, lenders may no longer claim a bad-debt deduction or refund claim for accounts found worthless on or after that date, and affiliated entities of a retailer are also restricted. Retailers themselves may still claim a bad-debt deduction when they otherwise qualify under the sales and use tax rules. (cdtfa.ca.gov)
Penalty for Tax Collected but Not Remitted
California Revenue and Taxation Code section 6597 imposes a 40% penalty on a person who knowingly collects sales tax reimbursement or use tax and fails to timely remit it to CDTFA. The statute contains an exception if the unremitted amount averages $1,500 per month or less, or does not exceed 25% of the total tax liability for the period in which the tax was collected, whichever is greater. (cdtfa.ca.gov)
Firearm and Ammunition Excise Tax (CFET)
California’s Firearm, Firearm Precursor Part, and Ammunition Excise Tax remains in force in 2026. The tax is 11% of gross receipts from retail sales in California of firearms, firearm precursor parts, and ammunition by licensed firearms dealers, firearms manufacturers, and ammunition vendors. This is a separate excise tax and should not be confused with ordinary sales tax. (cdtfa.ca.gov)
4. Filing Frequency, Prepayments, and EFT in 2026
CDTFA assigns filing frequency based on the sales tax reported or the taxable sales expected when you register. The agency uses filing bases such as monthly, quarterly, quarterly prepay, fiscal yearly, and yearly. In other words, the filing schedule is account-specific, so businesses should not assume every permit will be on the same cycle. (cdtfa.ca.gov)
2026 filing and payment rules
| Filing rule | 2026 rule | What to watch |
|---|---|---|
| Quarterly prepay | Required when estimated tax liability averages $17,000 or more per month and CDTFA notifies the taxpayer | You must make prepayments for the first two months of each quarter before the quarterly return is filed. (cdtfa.ca.gov) |
| Prepayment amount | Generally 90% of the month’s liability | Failure to make a required prepayment can result in a 6% penalty. (cdtfa.ca.gov) |
| Electronic funds transfer (EFT) | Required when average monthly sales/use tax liability equals or exceeds $10,000 over 12 months | High-liability accounts must pay electronically. (cdtfa.ca.gov) |
| Yearly reporting | CDTFA still uses yearly reporting bases for some accounts | For sales tax accounts, yearly returns are due January 31; for qualified purchasers/consumer use tax accounts, the due date is April 15. (cdtfa.ca.gov) |
If you are on a quarterly prepay basis, the practical takeaway is simple: do not wait until the quarterly return is due to think about the first two months of the quarter. CDTFA expects those prepayments to be made on time, and the penalty exposure is meaningful. (cdtfa.ca.gov)
5. Practical 2026 Scenarios
Scenario A: The Remote Seller
Profile: A Nevada-based retailer sells $520,000 of tangible personal property into California during 2026. Result: The seller crosses the $500,000 threshold and must register with CDTFA and collect the applicable California tax on taxable sales. (cdtfa.ca.gov)
Scenario B: The Marketplace Seller
Profile: A seller does all of its California business through a marketplace and also makes direct sales through its own website. Result: The marketplace sales count toward the $500,000 threshold, so the direct-sales channel cannot be analyzed in isolation. If all California sales are marketplace sales, CDTFA says the seller is generally not required to register solely for those marketplace sales. (cdtfa.ca.gov)
Scenario C: The Firearm Retailer
Profile: A licensed dealer sells a firearm in California in 2026. Result: The sale can be subject to ordinary California sales tax and, separately, the 11% CFET if the product and transaction fall within the statute. (cdtfa.ca.gov)
Scenario D: The Seller Who Collects Tax But Does Not Remit It
Profile: A retailer collects sales tax reimbursement from customers but does not send it to CDTFA on time. Result: A 40% penalty may apply unless the liability falls within the statute’s $1,500/month or 25% exception. (cdtfa.ca.gov)
6. Common Compliance Mistakes to Avoid
1) Using stale 2025 rates in 2026
The old “one-size-fits-all” rate assumption is still a mistake. CDTFA’s current city/county tables are effective April 1, 2026, and district taxes vary by location. (cdtfa.ca.gov)
2) Ignoring marketplace sales when testing nexus
Marketplace sales can count toward the $500,000 threshold even if the marketplace is the party collecting tax on those sales. (cdtfa.ca.gov)
3) Assuming bad-debt deductions still work the old way
If you are a lender or affiliated entity, the bad-debt deduction rules changed for accounts written off on or after January 1, 2025. (cdtfa.ca.gov)
4) Treating shipping and handling the same way
California generally does not tax a properly structured delivery charge in the same way it taxes handling. A separately stated delivery charge by common carrier or U.S. Mail is generally not taxable if it does not exceed actual cost, while handling charges are generally taxable. Combined “shipping and handling” charges often create partial-tax issues. (cdtfa.ca.gov)
5) Missing prepayment and EFT obligations
If your account is placed on quarterly prepayment or EFT, those obligations are not optional. CDTFA’s current guidance makes clear that prepayment and electronic-payment thresholds are monitored separately from your ordinary filing frequency. (cdtfa.ca.gov)
7. FAQ
Does California still use a $500,000 nexus threshold in 2026?
Yes. CDTFA still uses the $500,000 sales threshold for remote sellers. Marketplace sales count toward that threshold. (cdtfa.ca.gov)
Is California’s statewide sales tax rate still 7.25%?
Yes. The statewide base rate remains 7.25%, but the actual rate may be higher once local district taxes are added. (cdtfa.ca.gov)
Do shipping charges have to be taxed?
Not always. A separately stated delivery charge is generally not taxable when the goods are shipped by common carrier or U.S. Mail and the charge does not exceed the actual delivery cost. Handling charges are generally taxable, and combined shipping-and-handling charges need careful treatment. (cdtfa.ca.gov)
What is the penalty for knowingly collecting tax and not remitting it?
California’s penalty is generally 40% of the amount not timely remitted, subject to the statute’s $1,500/month or 25% exception. (cdtfa.ca.gov)
Is the firearm and ammunition excise tax still 11% in 2026?
Yes. CDTFA’s current guidance still states the CFET rate is 11% of gross receipts from covered retail sales. (cdtfa.ca.gov)
Do I still need to worry about BOI reporting for a California LLC or corporation?
For entities created in the United States, FinCEN’s March 26, 2025 interim final rule exempted domestic entities and their beneficial owners from BOI reporting. The old domestic BOI filing warning should no longer be used in a general California sales tax guide. (cdtfa.ca.gov)
Conclusion
For 2026, California sales tax compliance is less about memorizing a single rate and more about understanding where you have nexus, what rate applies at the delivery address, whether your account is on prepay or EFT, and whether any special tax regimes apply to your products. The most important current numbers to remember are $500,000 for remote-seller nexus, 7.25% for the statewide base rate, $17,000 for quarterly prepay monitoring, $10,000 for EFT, 40% for the unremitted-tax penalty, and 11% for CFET. (cdtfa.ca.gov)
If you sell into California, the safest 2026 workflow is to verify the rate by address, confirm whether marketplace sales count toward your threshold, and review your filing frequency before the return is due. (cdtfa.ca.gov)
