If your organization receives funding from a California Regional Center, you may be required to obtain an independent CPA audit or review under Welfare & Institutions Code §4652.5.


These compliance requirements are not optional and failure to meet them can result in placement on the Department of Developmental Services (DDS) “Do Not Refer” list.

Not sure whether your organization requires an audit or review?

Who Is Required to Obtain a Regional Center Audit or Review?

According to the Welfare & Institutions Code §4652.5, service providers that receive funding from a California Regional Center may be required to obtain an independent CPA review or audit each year.


Important: The thresholds are based specifically on the amount of funding received from California Regional Centers not your organization’s total gross revenue from all sources.


Annual Funding Thresholds


Your reporting requirement is determined by the total amount of Regional Center funding received during the State’s fiscal year (July 1 through June 30). Even though reporting may be completed on your fiscal‑year or calendar‑year basis, the funding threshold is measured using the State’s fiscal year.


$500,000 – $1,999,999 in Regional Center Funding

CPA Review Required


Organizations within this range must engage an independent CPA to perform a financial review in accordance with professional standards. A review provides limited assurance and includes analytical procedures and management inquiries.


$2,000,000 or More in Regional Center Funding

Independent Audit Required


Organizations receiving $2 million or more in Regional Center funding must undergo a full financial statement audit. An audit provides reasonable assurance and includes testing of transactions, evaluation of internal controls, and verification of compliance with Department of Developmental Services (DDS) reporting requirements.


Why the Distinction Matters


These requirements are designed to promote financial accountability and ensure compliance with Department of Developmental Services (DDS) oversight standards. Failing to meet the appropriate reporting level or misunderstanding how funding thresholds are calculated can result in compliance issues and potential referral restrictions.


If you are unsure which level applies to your organization, early planning and proper documentation are critical to avoiding last-minute complications.

What WIC §4652.5 Compliance Actually Requires

What Does WIC 4652.5 Compliance Include?


Welfare & Institutions Code §4652.5 establish financial transparency standards for organizations receiving funding from California Regional Centers. Compliance typically includes the following:


Independent CPA Engagement


An annual CPA Review or Audit must be conducted depending on your funding level.


Financial Reporting to Department of Developmental Services (DDS)


Completed reports must be submitted to the Department of Developmental Services (DDS) within required timelines following your fiscal year end.


85/15 Program Spending Compliance


Organizations must demonstrate that at least 85% of Regional Center funding is spent on direct program services.


Financial Statement Disclosures


Your financial statements must properly reflect revenue sources, expense classifications, and compliance representations.


Documentation & Record Retention


Supporting documentation must be maintained to substantiate revenue allocation and expense categorization.


Internal Control Considerations


Audits often evaluate financial processes and internal controls to ensure compliance with Department of Developmental Services (DDS) expectations.


Proper Submission Format


Reports must meet Department of Developmental Services (DDS) formatting and documentation standards to avoid rejection or delay.

Understanding the 85/15 Program Spending Rule

Under Department of Developmental Services (DDS) regulations, organizations receiving Regional Center funding must demonstrate that:


  • At least 85% of funding is used for direct program services
  • No more than 15% is allocated to administrative or overhead expenses


This calculation applies specifically to Regional Center funding not necessarily to your total organizational expenses.


Why Expense Classification Matters


Misclassification of expenses can unintentionally push an organization out of compliance. Items such as:


  • Salaries
  • Rent
  • Administrative payroll
  • Professional fees
  • Shared costs


must be carefully allocated and documented.


Improper classification is one of the most common issues identified during Regional Center audits.


Proactive Planning Reduces Risk


Proper bookkeeping throughout the year rather than waiting until audit season significantly reduces compliance risk and last-minute adjustments.

If you’re unsure whether your organization currently meets the 85/15 requirement, it’s best to review your reporting before your compliance deadline.

Consequences of Non-Compliance

What Happens If You Fail to Meet WIC §4652.5 Requirements?


Failure to comply with WIC §4652.5 requirements can result in serious operational consequences, including:


Placement on the Department of Developmental Services (DDS) “Do Not Refer” List


Regional Centers may suspend referrals until compliance is restored or even worse, you could lose your vendorization.


Payment Delays


Failure to submit required reports can delay reimbursement or future funding.


Contract Disruption


Non-compliance may impact vendor agreements or renewal status.


Increased Regulatory Scrutiny


Repeated reporting issues may trigger closer oversight or additional documentation requests.


Reputational Impact


Compliance issues can affect trust with Regional Centers and stakeholders.

The best way to avoid compliance issues is to prepare your audit well before your reporting deadline.
