What Is Commingling?
Commingling is the practice of mixing funds or assets that should be kept separate. This commonly occurs in finance when personal funds are combined with business funds, or when client funds are mixed with an investment professional's own assets30, 31. Commingling falls under the broader financial category of Regulatory Compliance. The practice can lead to significant issues, including accounting difficulties, legal complications, and a loss of asset protection.29
Commingling can take various forms, from a small business owner paying personal utility bills from a business account to a financial advisor improperly mixing client funds28. In the legal and financial services industries, commingling client funds with personal funds is generally illegal and constitutes a serious breach of fiduciary duty.26, 27
History and Origin
The concept of separating funds has deep roots in financial regulation, evolving alongside the complexity of financial markets. In the United States, the history of financial regulation is characterized by a fragmented system with responsibilities split across federal and state agencies, as well as self-governing associations24, 25. Early regulatory efforts, even back to the Constitutional Convention in 1787, laid the groundwork for the oversight of financial activity22, 23.
The necessity of strict rules against commingling became particularly evident with the rise of various financial intermediaries and the increasing trust placed in them by the public. For instance, the Securities and Exchange Commission (SEC) has long-standing rules, such as Rule 206(4)-2 under the Investment Advisers Act of 1940, commonly known as the "Custody Rule," which explicitly prohibits investment advisers from commingling client assets with their proprietary assets20, 21. This rule ensures that client funds are held separately by qualified custodians, protecting investors in cases of an advisor's insolvency19. Similarly, the Financial Industry Regulatory Authority (FINRA) has rules to prevent broker-dealers from the improper use of customers' securities or funds18.
Key Takeaways
- Commingling involves mixing funds or assets that should be kept separate, typically personal with business, or client with professional accounts.
- It is strictly prohibited in regulated financial sectors to protect investors and ensure financial integrity.

Formula and Calculation
Commingling does not involve a specific financial formula or calculation, as it is a practice related to the handling and separation of assets rather than a quantitative measure. It is a procedural and ethical concern, not a mathematical one. Therefore, no formula section is applicable.
Interpreting Commingling
Interpreting commingling primarily involves recognizing when the separation between different sets of funds or assets has been breached. In a business context, any instance where personal expenses are paid from a business account, or business income is deposited into a personal bank account, constitutes commingling.16, 17 For financial professionals, such as investment advisers or lawyers, commingling means blending client funds with their own operating funds or personal accounts14, 15.
The interpretation of commingling often centers on the intent and adherence to professional ethics and regulatory guidelines. Even unintentional commingling can lead to severe penalties due to the strict liability associated with maintaining distinct financial boundaries, particularly concerning client assets. Maintaining clear audit trails and distinct records for each financial entity or client is paramount to demonstrate proper handling of funds and avoid the appearance of commingling.
Hypothetical Example
Consider Sarah, a freelance graphic designer who operates her business as a sole proprietorship. She earns revenue directly from clients and often incurs business expenses for software, marketing, and office supplies. Initially, Sarah uses a single checking account for both her personal and business transactions. She deposits client payments into this account and pays for her groceries, rent, and business software from the same account.
One month, Sarah experiences a dip in business income and uses her personal savings, also in the same account, to cover a large business software subscription. This scenario illustrates commingling because her personal funds (savings) and business funds (client payments and business expenses) are combined and not easily distinguishable. If Sarah were to face an audit, it would be difficult for her to clearly delineate business income and expenses from personal ones, potentially leading to tax complications or a "piercing of the corporate veil" if her business were structured as an LLC. To avoid this, Sarah should maintain a separate business bank account and a distinct personal bank account, transferring funds between them only with clear documentation for salary or owner's draw.
Practical Applications
Commingling is a critical concept with practical applications across various financial and legal domains:
- Investment Management: Registered investment advisers are strictly prohibited from commingling client assets with their own or those of other clients. The SEC's Custody Rule mandates that client funds and securities be held by qualified custodians in separate accounts12, 13. This ensures investor protection and prevents the misuse of funds.
- Legal Profession: Lawyers are required to keep client trust accounts separate from their operating accounts. Mixing client settlement funds with firm operational funds is a classic example of commingling in the legal field, which can lead to disciplinary actions or disbarment10, 11.
- Small Business Operations: Business owners, especially those with sole proprietorships or LLCs, must maintain strict separation between personal and business finances. Using business credit cards for personal purchases or depositing business income into a personal account are common forms of commingling that can jeopardize limited liability protection and complicate tax reporting8, 9.
- Real Estate: In real estate, escrow agents or brokers are entrusted with client funds, such as earnest money deposits. Commingling these funds with personal or brokerage operating funds is a serious violation that can result in license revocation and legal action.
- Retirement Plans: Employers must keep employee contributions to retirement plans (e.g., 401(k)s) separate from the company's operating funds.7 Failure to do so can result in severe penalties under ERISA (Employee Retirement Income Security Act) and other regulatory frameworks.
The push for financial institutions to prevent commingling has also extended to emerging areas like digital assets, with proposed legislation requiring custodians of payment stablecoins to separately account for reserves and prohibit commingling with their own assets6.
Limitations and Criticisms
While the prohibition against commingling is widely accepted as a fundamental principle of financial integrity and investor protection, its primary "limitation" is often the human element – the potential for accidental or intentional breaches of the rule. Critics or those impacted by its strict enforcement often highlight the challenges in maintaining absolute separation, particularly for small businesses or individual practitioners who may inadvertently blend funds.
One criticism is the complexity it can add to record keeping and financial management, especially for new entrepreneurs who may not fully understand the implications of mixing funds. While the intent of preventing fraud and ensuring accountability is clear, unintentional commingling can still lead to severe legal and financial repercussions, disproportionate to the actual harm caused in some minor instances. T5his underscores the need for clear guidance and robust internal controls.
Another area of discussion involves the nuanced interpretation of "custody" and "commingling" in evolving financial landscapes, such as with pooled investment vehicles or new asset classes. For instance, the SEC has periodically issued risk alerts detailing common deficiencies found in investment adviser examinations related to the custody rule, including instances where advisers commingled client, proprietary, and employee assets into one account, even when not intending to defraud clients. 3, 4This indicates that even regulated entities can struggle with compliance, highlighting the ongoing need for vigilance and clarification from regulators.
Commingling vs. Intermingling
While "commingling" and "intermingling" are often used interchangeably to describe the mixing of different things, in finance, "commingling" typically carries a specific and often negative connotation related to the improper or prohibited mixing of funds or assets.
| Feature | Commingling | Intermingling |
|---|---|---|
| Financial Context | Generally refers to the improper or illegal mixing of funds that should be separate (e.g., client funds with personal funds). | Can refer to any mixing or blending, often with a neutral or even positive connotation (e.g., intermingling of investment strategies). |
| Legal/Regulatory | Often a violation of regulatory compliance, fiduciary duties, or ethical standards. | No inherent legal or regulatory implication unless it leads to a lack of transparency or a breach of duty. |
| Consequences | Can lead to severe penalties, including fines, loss of license, legal liability, or "piercing the corporate veil." | Typically no direct negative consequences unless it obscures financial clarity or leads to other violations. |
| Intent | Can be unintentional, but the consequence of the act itself is often the focus. | Usually describes a descriptive action without implying wrongdoing. |
For example, an investment fund might "intermingle" various types of securities within its portfolio to achieve diversification. However, if an investment adviser were to "commingle" those fund assets with their personal checking account, it would be a serious regulatory violation.
