If you have received a compliance letter from your Regional Center, you are not alone.

Welfare & Institutions Code §4652.5 requires every California Regional Center vendor receiving $500,000 or more in annual funding to engage an independent CPA. Below $2 million, you need a review. At $2 million and above, you need a full audit. Both must be submitted within 9 months of your fiscal year end.

Most CPA firms do not understand the rules. They miss the 85/15 program spending test. They classify expenses incorrectly. They miss deadlines. The result: management letter findings, payment delays, and — in the worst cases — placement on the DDS "Do Not Refer" list.

That is not what we do here. Guidepost specializes in Regional Center vendor compliance. It is what our workpapers, our staff training, and our engagement timelines are organized around.

First-year engagements run higher due to setup and opening-balance procedures.

Common Questions

Frequently Asked Questions.

Under WIC §4652.5, every California Regional Center vendor receiving $500,000 or more in annual funding must submit an annual CPA review or audit. The letter is most likely a reminder that your organization has outstanding reports for one or more fiscal years.
A review provides limited assurance through analytical procedures and inquiries; an audit provides reasonable assurance through transaction testing and internal control evaluation. Your required level depends on the amount of Regional Center funding you receive — below $2M requires a review, $2M and above requires a full audit.
Per WIC §4652.5, Regional Centers must report non-compliance to the Department of Developmental Services. Consequences range from payment delays and increased scrutiny to placement on the DDS "Do Not Refer" list — and in serious cases, termination of vendorization.
Reports are due 9 months after your fiscal year end. Once finalized, the report and the management letter must be forwarded to your Regional Center within 30 days of receipt from the CPA.
Most review engagements range from $7,000 – $15,000 and audit engagements from $15,000 – $25,000, depending on scope and complexity. Fixed fee quoted after a brief intake call. First-year engagements run higher due to setup and opening-balance procedures.
Yes. If your report is issued with an unmodified opinion, no material issues are identified, and corrective actions have been implemented for any management letter findings, you may be eligible to request a two-year exemption. We help vendors evaluate eligibility and prepare the request.
