Illinois Court Ruling Analysis Reinforces Tax Liability in Income Assignment Cases

A recent analysis of an Illinois appellate court decision in Blonstein v. Hamill Property Partnership serves as a critical reminder for business owners regarding the “assignment of income” doctrine, a long-standing U.S. tax principle. The ruling highlighted that the legal obligation to pay taxes on earned income cannot be shifted to another person or entity, even if the actual payment is redirected to satisfy a separate debt or obligation.

The case underscores a fundamental rule that the individual or entity that earns the income is responsible for the corresponding tax liability. This principle holds true regardless of complex arrangements that direct funds to third parties, a common practice in business disputes and settlements.

In our experience, business owners, particularly in partnerships or closely-held LLCs, often use inter-company transfers to manage cash flow or settle obligations. However, the Blonstein case is a classic example of how these arrangements, if not structured with tax law in mind, can lead to unintended and costly consequences. The IRS is laser-focused on substance over form, meaning it will look past the paperwork to see who truly earned the money.

The original dispute involved Michael Blonstein, who was owed compensation for services rendered to the Hamill Property Partnership, including site procurement and securing leases. The defendants argued that Blonstein was not entitled to damages because he owed a larger, outstanding debt of $268,000 to a related entity, DiMucci Realty. The right to collect this debt was then passed through a complex chain of assignments to other commonly-owned companies, including DiMucci Real Estate Company, DiMucci Construction, and finally United Administrative Services.

The defendants’ expert witness, a certified public accountant, testified that because the debt Blonstein owed exceeded the value of the services he rendered, he was entitled to zero dollars in damages. While the court grappled with the contractual and unjust enrichment claims, the tax implications of such an arrangement are governed by the assignment of income doctrine.

According to this legal doctrine, income is taxed to the person who earns it or owns the property that generates it. A taxpayer cannot avoid tax liability by simply instructing a client or employer to pay a third party, such as a family member or a creditor. For example, if a consultant performs $10,000 worth of services and instructs the client to pay that $10,000 directly to a lender to pay down a personal loan, the consultant must still report that $10,000 as taxable income. The law treats the transaction as if the consultant received the income and then used it to pay the debt.

The primary purpose of this rule is to prevent tax evasion. Without it, high-income individuals could assign their earnings to relatives in lower tax brackets or use assignments to obscure their true income from tax authorities.

We see this frequently in shareholder disputes or partnership dissolutions where payments are structured to go to third parties. The key takeaway is that you cannot assign away your tax liability. Proper documentation and a clear understanding of who earned the income are critical. This is precisely the kind of complex situation where professional guidance on tax preparation and compliance is not just helpful, but essential to avoid future audits and penalties.

This principle extends to various business and personal scenarios, including lawsuit settlements and divorce proceedings. In divorce, for instance, a court may allocate debt based on income disparity or financial contributions, but the underlying income that services that debt remains taxable to the person who earned it. Similarly, if a lawsuit settlement is considered taxable income, the plaintiff is liable for the tax even if they arrange for the funds to be paid into a trust or directly to family members.

There is a narrow exception to this doctrine involving a formal principal-agent relationship. When an agent collects income from a third party specifically on behalf of a principal, the income is generally taxable to the principal, not the agent. In this legally defined structure, the agent is merely a conduit for the funds and has no claim of ownership over the income. This is fundamentally different from a business owner unilaterally redirecting their own earned income to another party.

Ultimately, the assignment of income doctrine is a foundational element of U.S. tax law. While creative business arrangements can be effective for operational purposes, they do not create loopholes in tax liability. Proactive tax planning is the only reliable way to manage these complex issues and ensure compliance.

As business structures and transactions become more intricate, owners and their advisors must remain vigilant about the principles upheld in cases like Blonstein. The IRS continues to scrutinize arrangements that appear to shift income for tax avoidance purposes, and future court rulings are expected to consistently reinforce the doctrine that tax liability follows the earner, not the ultimate recipient of the funds.
