If you own a business in California, and you expect to be making taxable sales, you must register with us for a seller’s permit and file regular sales and use tax returns. You may be required to register for other licenses or accounts using our online registration service and file other returns. Listed below are other tax and fee programs that may be applicable to the agricultural industry.
If you make sales to farmers who use diesel fuel for tax-exempt farming purposes, you may apply for an Ultimate Vendor license. As an ultimate vendor, you may file a claim for refund of the diesel fuel tax you paid on your purchase of diesel fuel that you sold to an ultimate purchaser without collecting the diesel fuel tax reimbursement. All claims for refund for sales of diesel fuel to farmers must be supported by a BOE-608, Certificate of Farming Use, accepted in good faith.
If you own an underground storage tank (UST) to store petroleum products, and it is even partially underground, you are required to register with us to file UST fee returns and pay any fee amounts due based on the number of gallons of petroleum products placed in the UST during the reporting period. For rates see the Underground Storage Tank Maintenance Fee Schedule.
In most cases, if you lease an underground storage tank, you are considered an operator and are not required to pay the fee. However, as an operator, you may have an agreement with the owner to report and pay the fee.
Online Registration — Register with us for your seller’s permit and apply for any of the licenses, permits, or accounts listed above.
Notice of Business Change – Keep your information current by using the links below and notifying us of any business changes.
In general, the sale of farm equipment and machinery is taxable. However, certain sales and purchases are partially exempt from sales and use tax.
The partial exemption applies only to the state general and fiscal recovery funds portion of the sales tax, currently 5.5%.
To calculate the tax rate for qualifying transactions, subtract 5.5% from the sales tax rate that would normally apply at the location where the purchase is made. For example, if the current tax rate in your area is 9%, the tax rate for a qualifying transaction would be 3.5%.
Note: The rate for the state general and fiscal recovery funds portion of the sales tax is subject to change. The rates used in this example are for demonstrative purposes only. You must use the rate in effect at the time of the sale, current rates can be found on our website.
Three requirements must be met for the partial exemption to apply. The item must be:
If any of the first three requirements is not met, the partial exemption does not apply and the sale or purchase is fully taxable.
When a lease meets the three requirements above, and the lease payments are taxable, the lease may also qualify for the partial exemption.
Mobile transportation equipment does not qualify for the exemption.
A Qualified Person
A “qualified person” is one whose business falls within the specified Standard Industrial Classification (SIC) Codes listed below:
For a full list of applicable SIC Codes, please see Appendix C of publication 66, Agricultural Industry. For more information on SIC Codes please select SIC/NAICS Search from the index on the Occupational Safety and Health Administration (OSHA) website.
When you make a sale that qualifies for a partial exemption, you must obtain a valid exemption certificate from your buyer.
To be valid, the buyer or buyer’s representative must do all of the following:
*A certificate will be considered timely if it is given at any time before the seller bills the purchaser for the property, or any time within the seller’s normal billing and payment cycle, or any time at or prior to delivery of the property to the purchaser.

If you otherwise qualify for the partial farming equipment, your solar power facilities may also qualify.
If your solar power facilities are tied to the local power grid, but not directly attached to qualifying farm equipment, it may still qualify for the partial exemption if they are designed to generate power for such equipment and machinery.
How does a system qualify?
What support do I need to claim the partial exemption?
It is important you document the annual amount of electricity consumed by qualifying farm equipment and machinery for the first 12 months after the solar power facility is operating.
For more information see our November 2012 Special Notice: Solar Power Facilities May Qualify as Farm Equipment
Most sales and/or purchases of diesel fuel are taxable. However, a partial sales and use tax exemption exists for certain sales and purchases of diesel fuel used in farming activities or food processing.

For diesel fuel excise tax purposes, a farmer may purchase diesel fuel tax without paying the excise tax by issuing an exemption certificate to his/her vendor, or by purchasing dyed diesel fuel.
Dyed diesel fuel may not be used to operate a vehicle on any public highway in this state. There are severe penalties for using dyed diesel fuel on the highway (Either $10 for every gallon of diesel involved or $1,000, whichever is greater.)
To claim the exemption for the excise fuel tax the diesel fuel must be used:
Please note that transporting/hauling agriculture products from the farm/ranch to buyers is not an exempt use of diesel fuel for excise tax purposes.
Your diesel fuel vendor may provide you with a BOE-608 that you must complete to purchase diesel fuel for farming activities without paying the excise tax. The farmer exemption certificate meets criteria established by the Internal Revenue Service. To be valid, all requested information on the certificate must be provided. You will need to note on the certificate if it covers a particular purchase, all purchases, or a percentage of your purchases. You must annually renew your exemption certificate.
For further information, see Diesel Fuel Tax Regulation 1431, Diesel Fuel Used on a Farm for Farming Purposes.
In California, all sales are taxable unless the law provides a specific exemption. In most cases, taxable sales are of tangible personal property, which the law defines as an item that can be seen, weighed, measured, felt, or touched.
Use tax is a companion to California’s sales tax, and is due whenever you purchase taxable items without payment of California sales tax from an out-of-state vendor for use in California. You also owe use tax on items that you remove from your inventory and use in California when you did not pay tax when you purchased the items. To pay use tax, report the purchase price of the taxable items under "Purchases Subject to Use Tax" on your sales and use tax return. Those purchases become part of the total amount that is subject to tax.
Generally, sales of animal-related products, such as tack, cages, and pet supplies are taxable. However, some sales of animals and supplies are exempt from tax.
Tax does not apply to the purchase or sale of food animals that are commonly used in producing food or are intended for human consumption. See publication 66 for a list of common food animals.
Sales of animals that do not meet the definition of food animals are taxable sales, regardless of their use. See publication 66 for a list of common nonfood animals.
Feed includes grain, hay, seed, kibble, and similar products. Tax does not apply to sales of feed for food animals.
Some feed, like alfalfa, can be used for either food or nonfood animals. When selling this type of product, you should obtain a feed exemption certificate to support the exempt sales. You should itemize all invoices that include taxable and nontaxable sales.
You do not need a seller’s permit or pay sales tax if the only products you sell are feed for the following:
Hay growers fall in this category provided they either:
You do not need exemption certificates for the following nontaxable sales:
Feed sold for a nonfood animal is generally taxable. There are two exceptions, if the feed is sold for the following purposes, you may accept a feed exemption certificate:
Facilities that charge a flat fee to their customers are responsible for paying the tax on items they purchase such as feed, grains, hay or other merchandise.
Facilities that separately itemize taxable charges for the feed they sell may purchase the items with a resale certificate and they are required to report those taxable sales.
Note: if a boarding or training facility boards animals owned by ranchers and farmers, items they purchase may be eligible for a partial exemption described under Farming Exemptions.
Under certain circumstances, tax does not apply to your sale, or a buyer’s purchase or use of drugs or medicines that will be administered to animals, as explained below. Drugs and medicines are products intended to prevent or control disease in animals.
