California IFTA Fuel Tax

IFTA Reporting and Filing Requirements in California

Who Needs IFTA Registration in California?

Motor carriers based in California must obtain an International Fuel Tax Agreement (IFTA) license if they operate qualified motor vehicles (QMVs) in two or more IFTA member jurisdictions.

A vehicle qualifies for IFTA in California when it is used to transport people or property and meets any of the following conditions:

• Has two axles and a gross vehicle weight or registered gross vehicle weight of more than 26,000 lbs. 
• Has three or more axles, regardless of weight
• Is used in combination when the combined or registered gross vehicle weight is more than 26,000 lbs. 

Recreational vehicles used only for personal or recreational purposes are generally not considered qualified motor vehicles for IFTA..

What Are the IFTA Reporting Requirements in California?

If California is your base jurisdiction and you hold a California IFTA license, you must file quarterly IFTA fuel tax returns with the California Department of Tax and Fee Administration (CDTFA).

Your California IFTA return reports your travel and fuel purchases across all IFTA member jurisdictions.

Instead of filing separate fuel tax returns in every state or province where you operate, you file one quarterly IFTA return with California. On that return, you report:

• Miles traveled in each jurisdiction
• Taxable fuel purchased in each jurisdiction
• Taxes owed or credits due based on current IFTA fuel tax rates

After your return is submitted, California handles the distribution of fuel taxes to the appropriate IFTA jurisdictions.

You must file a quarterly IFTA return even if:

• Your IFTA fleet did not operate during the reporting period
• No fuel purchases were made
• No tax is due
• Your qualified vehicles operated only in California during that quarter

If you no longer need IFTA, you may need to close or cancel your IFTA account instead of simply skipping future returns.

How to File an IFTA Report in California

Once your report is complete, you can:

1. Prepare Your IFTA Report

   Before filing your California IFTA return, gather and organize your mileage and fuel records. With eIFTA, a service by Truckopedia, you can easily prepare your filing by:

   • Recording total IFTA miles traveled in each member jurisdiction
   • Adding non-IFTA miles traveled, if applicable
   • Entering total fuel placed into qualified motor vehicles
   • Recording tax-paid fuel purchases by jurisdiction
   • Generating an accurate IFTA report ready for filing

   Keeping your mileage and fuel records organized helps simplify the filing process and ensures your IFTA report is ready for submission.

2. Submit Your IFTA Return

   Once your IFTA report is ready, you can submit your return by:

   • Downloading your California-compatible IFTA report
   • Filing your return through the CDTFA Online Services portal
   • Reviewing your return details before submission
   • Submitting your return and paying any tax due online

   California IFTA returns are filed through CDTFA Online Services, making it easier to file returns, make payments, and manage your IFTA account.

What Are the IFTA License Costs and Fees in California?

California charges an annual IFTA license fee of $10 per carrier. IFTA decals cost $2 per set, and one set is required for each qualified motor vehicle.

Your California IFTA account must remain in good standing to renew your IFTA license, receive decals, and keep your account active.

What Are the IFTA Penalties and Interest in California?

California requires IFTA returns and any payments due to be filed on time. If you file late or fail to pay the full amount due by the deadline, penalties and interest may apply.

California generally imposes a late penalty equal to:

• $50, or
• 10% of the total tax due,

whichever amount is greater.

Interest may also apply to unpaid tax balances. Interest begins after the IFTA filing due date and continues until the balance is paid in full.

Even if no tax is due, your quarterly IFTA return must still be filed on time to keep your account in good standing.

Maintaining accurate mileage and fuel records is also important. Poor or incomplete records may lead to additional assessments if your account is reviewed or audited.

How Do You Renew an IFTA License in California?

California IFTA licenses and decals must be renewed every year through the California Department of Tax and Fee Administration (CDTFA).

Annual IFTA renewal begins December 1. Eligible carriers can renew their California IFTA license and request decals through the CDTFA Online Services portal.

Your renewal may be delayed or denied if:

• You have unpaid IFTA taxes, penalties, or interest
• Required IFTA returns have not been filed
• Your account is not in good standing

Current IFTA decals are generally valid through the IFTA renewal grace period if the carrier has renewed on time.
