How do I File a Claim?
You may file a claim for refund using CDTFA’s online services. To submit a claim for refund, simply login using your username and password and click on the account for which you want to request a refund. Click on the More link under the I Want To section. Then select the Submit a Claim for Refund link and follow the prompts.
You may also file a claim for refund using a CDTFA-101, Claim for Refund or Credit, or by sending us a letter. Your claim must state all of the following:
The specific reasons you paid too much tax.
The amount of tax you overpaid. If you're not yet sure of the amount, you may file for an unspecified amount.
The reporting period or periods for which you paid too much tax. Your claim can cover more than one reporting period.
You must sign and date your claim. Please include your
phone number so that we can contact you if we have questions or need more information. To expedite the processing of your claim, you should send supporting documents such as copies of invoices or exemption certificates and an amended return(s) along with your claim. Please see the Required Information section for more information.

What is the Deadline for Filing a Claim for Refund?
If you believe you have paid more tax than you owe, and you wish to be refunded, you must file a timely claim for refund, otherwise the CDTFA is unable to issue a refund. Whichever of the following dates occurs last is your deadline to file a timely claim for refund:
Three years from the due date of the return on which you paid too much tax (except for tax on insurers). Filing an application for
registration of your vehicle with the Department of
Motor Vehicles (DMV) is generally considered a return and relieves you of further obligation to file with the CDTFA.
Six months from the date you overpaid tax.
Six months from the date a determination (billing) became final, for most programs.
Three years from the date we collected an involuntary payment, such as from a levy or lien (except for Motor Vehicle Fuels Tax and Tax on Insurers as the collection for these tax programs are handled by the State Controller’s Office).
Be sure to file your claim for refund by the applicable deadline. If you don't file on time, you will not receive a refund, even if you paid too much tax.
Some special tax and fee programs, including fuel tax programs, have special requirements. Be sure to review the Program Specific Guidelines section for more information.
