Customs Statement of Proposed Liability (CDTFA-537)

Why did I receive this letter?

We received information from the U.S. Customs and Border Protection (CBP) indicating that you imported items into California for storage, use, or other consumption in this state during the previous calendar year. The amount listed on this letter is the tax due for the declared value of the imports for the identified year.

Generally, if sales tax would apply when you buy physical merchandise in California, use tax applies when you make a similar purchase without tax from a business located outside the state. For these purchases, you are required to pay the use tax separately. Use tax is due on or before April 15 following the year in which the purchase was made.

What do I need to do?

What if I disagree with the amount due?

If you believe use tax is not due, you will still need to file a return, claim an exemption, and upload copies of your supporting documentation. If a return or payment is not received within 15 days from the date of the letter, a Notice of Determination (billing) may be issued to you, as authorized by section 6481 of the Sales and Use Tax Law.
