What Form CDTFA-65 (2010) Is For

Form CDTFA-65 (2010) is used by California business owners to officially notify the California Department of Tax and Fee Administration that they are closing, selling, or restructuring their business. It serves as formal documentation to cancel a Seller's Permit and end the obligation to collect or report sales and use tax. This form ensures the business is no longer liable for future taxes on tangible personal property and initiates the process of refunding any security deposit on file.

When You’d Use Form CDTFA-65 (2010)

This section explains the situations that require Form CDTFA-65 (2010).

  • Permanent business closure: This applies when a business ceases to sell tangible personal property and must notify the California Department of Tax and Fee Administration to cancel its Seller's Permit and terminate its reporting obligations.

  • Business sale or transfer: This applies when a business changes ownership. Filing the form helps prevent the seller from being liable for sales or use tax owed by the buyer and documents the purchase price for clearance purposes.

  • Change in business structure: This includes changes such as converting from a sole proprietorship to a corporation, which requires closure of the existing permit and issuance of a new business license and registration.

  • Partnership changes: This applies when a new partner joins, or an existing one leaves, requiring the dissolution of the old partnership and the filing of a new account.

  • Ending voluntary collection programs: This applies to small sellers of prepaid mobile services who voluntarily collected local sales tax and have now chosen to stop doing so.

Key Rules or Details for 2010

Several vital rules apply when completing Form CDTFA-65 (2010).

  • Nontransferable Seller's Permit: A Seller's Permit may only be used by the original business entity; using it after closure or transferring it to another owner violates California tax law and may result in administrative and judicial litigation.

  • Fixture and Equipment Sales Rules: If you sell business fixtures or equipment within 60 days of closing, the sale is typically taxable. Sales beyond 60 days but within one year may also be taxable if a sales contract or lease existed at the time of closeout.

  • Inventory and Use Tax Requirements: If you retain tax-free inventory purchased with a resale certificate, such as a California General Resale Certificate or Form 5000A, for personal use, you must report and pay Use Tax on those items.

  • Final tax return documentation: The California Department of Tax and Fee Administration requires a complete final sales and use tax return to be filed before account closure can proceed.

  • Security deposit handling: If documentation such as Form ST-EX-A1, escrow instructions, or the bill of sale is missing, the CDTFA may delay refunding your security deposit for up to 30 days.

  • Certificate and exemption documentation: All claimed exemptions must be supported by valid exemption certificates, such as the Border States Uniform Sale for Resale Certificate, and must be retained for compliance purposes.

Step-by-Step (High Level)

These steps provide a high-level overview of how to complete and submit Form CDTFA-65 (2010).

  • Gather required information: Collect your account number, business closure date, forwarding address, inventory status, fixture and equipment sale details, and business record location.

  • Complete Section I: Enter your business name, Seller's Permit number, daytime phone number, and mailing address so the California Department of Tax and Fee Administration can correctly identify your account.

  • Complete Section II: Provide the business closure date, whether inventory was used personally, and the disposition of tangible personal property; if sold, include the buyer's name, purchase price, and contact details.

  • Prepare supporting documents: Attach your final tax return, payment for outstanding liabilities, resale certificate documentation, escrow instructions, and a bill of sale if applicable.

  • Submit the form: Mail the completed form and attachments to the CDTFA address listed, or use their Online Services portal to file electronically for faster processing.

  • Respond to follow-up if needed: The CDTFA may contact you to request clarification or missing information; a timely response will help expedite account closure.

Common Mistakes and How to Avoid Them

These standard errors often delay or complicate the closeout process for Form CDTFA-65 (2010).

  • Missing final sales tax return: Always file your final tax return along with the form to avoid delays in closing your Seller's Permit account.

  • Unreported personal use of inventory: Report any inventory purchased for resale that you later used personally to avoid assessments for unreported Use Tax.

  • Incomplete business sale documentation: Submit all details about the sale, including the purchase price breakdown and resale certificate verification, to prevent processing delays.

  • Late notification of closure: File the form as soon as your business closes or is sold to avoid personal liability for unpaid State and Local Tax obligations incurred by the new owner.

  • Improper use of cancelled permits: Stop making taxable sales immediately after closeout to avoid legal penalties for using an invalid Seller's Permit.

  • Incorrect exemption documentation: Ensure that all exemption claims are supported by valid exemption certificates, such as those issued by Arizona or Arkansas, to meet audit requirements.

What Happens After You File

Once the California Department of Tax and Fee Administration receives your completed Form CDTFA-65 (2010) and all supporting documents, it begins reviewing the submission for accuracy and completeness. This includes verifying that your final sales tax return was filed, ensuring proper documentation for inventory and fixture sales, and checking for outstanding tax liabilities. If no issues are found, CDTFA will cancel your Seller's Permit and issue a security deposit refund, typically within 30 days. If additional review or audit is needed, processing may take longer.

FAQs

Can I file Form CDTFA-65 (2010) using the CDTFA’s online portal?

Yes, the California Department of Tax and Fee Administration allows account closures through its Online Services, which often results in faster processing than paper filing.

What happens to my Seller’s Permit number after my account is closed?

Once your account is closed, the Seller’s Permit number is permanently retired and cannot be reused for future business activities.

Do I still need to file a sales tax return if no sales occurred in the final period?

Yes, you must file a final sales tax return even if no sales occurred, as CDTFA requires confirmation that your business activity has ended.

How long should I retain records after filing Form CDTFA-65 (2010) with the California Department of Tax and Fee Administration (CDTFA)?

You must retain all business records for at least four years after closure, as the CDTFA may conduct audits during that period based on State Tax Notes or regulatory compliance requirements.

What happens if I fail to provide proper exemption certificates for tax-free sales?

Without valid documents such as a resale certificate, Arizona Resale Certificate, or Arkansas Exemption Certificate, CDTFA may reclassify those sales as taxable and assess additional liability.
