Basic Registration Information

Recordkeeping requirements

If a taxpayer holds a California seller's permit, they are required to maintain business records to verify that they have properly paid tax.

Your clients' records should be adequate enough that BOE representatives may:

  • Verify the accuracy of their sales and use tax returns; and
  • Determine if they have correctly paid the tax due on their sales and purchases.

Your client may be charged a negligence penalty if an audit reveals that their records are not adequate.

Records your client should keep include but are not limited to:

  • Normal books of account that show their business income and expenses.
  • Documents of original entry, such as invoices, receipts, job orders, purchase orders, contracts, or other documents used as the basis for their books of account; and
  • All schedules or working papers used in preparing their sales and use tax returns.

Your clients' records need to show:

  • The gross receipts from all of your business income, including sales, leases, service charges, and labor income;
  • All of the deductions claimed on your sales and use tax returns, along with supporting documents for those deductions; and
  • The total purchase price, including receipts, for all items you purchase for; resale, lease, or your own use.

The level of detail required varies by industry. Records need to be adequate enough for the BOE to determine the date of sale, what your clients sold, all taxable and nontaxable charges, and how much tax was applied to the sale. It is important that they keep all documents to support nontaxable sales.

Records should be retained for at least four years. If your client is being audited, retain all records that cover the audit period until the audit is complete, even if it is longer than four years.


In general, accounts are subject to audit in three-year intervals, at the time a permit is closed out, or in connection with another permit held by the taxpayer.

The objective of an audit is to verify that taxpayers are correctly reporting taxes and fees on their sales and use tax returns. You may be designated to represent your clients in an audit.

It is important to remember that the conduct of audits is governed by law and Board of Equalization policy. In particular, you should keep in mind that:

  • Our auditors will impartially determine whether you have reported the correct amount of taxes or fees. Overpayments, as well as underpayments, are considered during an audit.
  • Records are required to be provided according to the provisions of Regulation 1698, Records.
  • Our audit program is intended to correct errors that result in underreporting or over reporting and to inform you how to properly report your taxes or fees. During an audit, you may ask any questions you have about the law governing taxes or fees or your reporting requirements.
  • Our auditors are expected to conduct audits in a professional, courteous and helpful manner.
  • Frequently, audits do not result in any change in tax or fee liability.

The following materials can help you to prepare if your client is selected for audit.
