Sales tax compliance becomes complex when businesses expand, restructure, or acquire other companies. A critical concept that finance professionals must understand is successor liability—the risk of inheriting unpaid sales tax obligations from another entity. This guide explains successor liability clearly, provides strategies to manage and mitigate risks, and discusses how automated tools like Commenda can simplify compliance.

What Is Successor Liability?

Successor liability occurs when a business becomes legally responsible for another company’s debts, including unpaid sales taxes, after acquiring or continuing its operations or assets. Even if your acquisition agreement explicitly excludes liabilities, state tax laws often override private contracts, making successor liability unavoidable in certain cases.

How Successor Liability Affects Sales Tax

Many states have regulations enforcing successor liability:

  • Stock Purchase: Automatically transfers all tax liabilities to the buyer.
  • Asset Purchase: States may hold buyers responsible for unpaid taxes through “bulk sale” provisions.

For instance, states like Pennsylvania and Michigan explicitly require buyers to secure tax clearance certificates from sellers during transactions. Without clearance, buyers risk inheriting significant tax debts.

Example:

In California, a buyer purchased restaurant assets without obtaining clearance certificates. Later, the buyer was held liable for the seller’s unpaid sales taxes due to failure to notify tax authorities. Proper due diligence and compliance with state-specific requirements like tax clearances are crucial to avoid unexpected liabilities.

Strategies to Mitigate Successor Liability

1. Creating an “OldCo” and “NewCo” Structure

Finance professionals sometimes consider creating separate entities—OldCo (holding past liabilities) and NewCo (carrying forward clean operations).

Best Practices:

  • Fair Market Value Transfer: Ensure assets transferred to NewCo from OldCo are valued accurately and purchased fairly.
  • Clear Separation: Demonstrate clear differences in ownership, management, location, and operations between OldCo and NewCo to minimize continuity and successor liability claims.

However, transferring assets without adequate consideration or simply shifting operations can result in a state classifying NewCo as a continuation of OldCo, thus inheriting its liabilities.

2. Subsidiary and Holding Structures

Structuring a new entity as a subsidiary can limit visibility:

  • Different branding: Use distinct names, branding, and market presence.
  • Separate Operations: Maintain different physical addresses, employees, and banking details.

Although this can temporarily reduce visibility, tax authorities have methods to uncover these relationships, emphasizing the importance of legitimate structuring and compliance.

Managing Compliance Risks and Audits

State tax authorities use various methods to identify companies avoiding nexus registration and sales tax obligations:

  • Data matching with IRS and shipping records.
  • Public record searches and audits of related businesses.
  • Nexus questionnaires and whistleblower tips.

To minimize these risks:

  • Maintain detailed and compliant documentation.
  • Be cautious of publicly advertising trade activities in nexus-sensitive states without proper registration.
  • Promptly address nexus questionnaires with professional assistance.

Voluntary Disclosure Agreements (VDAs)

VDAs offer companies the opportunity to proactively address past sales tax liabilities by voluntarily disclosing and settling them under favorable terms:

  • Reduced look-back periods.
  • Penalty abatement.
  • Protection from criminal charges.
  • Initial anonymity during negotiations.

VDAs are strongly recommended if preparing for investment, acquisition, or general corporate restructuring, as they significantly reduce compliance risks.
