How Sellers Hide Liabilities: Common Tactics

When buying a business, hidden liabilities are a major risk. Sellers often use tactics to conceal debts, legal issues, or financial obligations, inflating the business's value and leaving buyers with unexpected costs after the deal. These liabilities can include unreported debts, unpaid taxes, hidden lawsuits, or undisclosed employee benefits.

Key Takeaways:

• Why it happens: Sellers hide liabilities to boost valuation and attract buyers.
• Common tactics: Manipulating financial statements, using off-balance-sheet arrangements, withholding information, and timing revenue or expenses to mislead buyers.
• Impact on buyers: Unexpected costs like unpaid taxes, lawsuits, or contract issues can reduce post-acquisition value by 20-30%.
• How to spot them: Conduct detailed financial reviews, verify legal and tax compliance, review contracts and employee records, and use forensic accountants or technology tools.
• Protect yourself: Use indemnification clauses, escrow accounts, and representation & warranty insurance in deal structures.

The article breaks down these tactics, explains their consequences, and provides practical steps to mitigate risks during due diligence.

How $60K in Hidden Liabilities Nearly Killed the Deal

Types of Hidden Liabilities

When buying a business, hidden liabilities can pose serious risks. Understanding these liabilities and spotting them during a thorough business acquisition checklist process is vital. Below are five key types of hidden liabilities and how to identify them early.

Unreported Debts and Off-Balance Sheet Obligations

These liabilities can seriously impact the value of your acquisition. For instance, non-assignable loans with below-market rates might not transfer to you, leaving you to refinance at higher rates. Other concerns include "phantom liabilities" like fake vendor invoices or undisclosed liens that could emerge after closing, allowing creditors to claim assets. To uncover these, review the general ledger and verify details directly with banks.

Tax and Payroll Obligations

Tax-related liabilities can lead to hefty penalties. Sellers might underreport payroll taxes or pay employees off the books to avoid workers' compensation costs. In one case, a moving company concealed nearly half its labor expenses this way. Additional risks include unpaid VAT or pension contributions. Comparing tax returns with payroll records and requesting tax clearance certificates from the IRS can help expose these liabilities before they escalate into federal fines.

Legal and Regulatory Issues

Legal and regulatory problems can remain hidden if sellers fail to disclose pending lawsuits or other issues that don't meet strict accounting thresholds for reporting.

"If future events cannot be foreseen with probability, a loss contingency is not recorded. This is fine for financial reporting purposes, but... a buyer will not be constrained by accounting pronouncements in getting to the bottom of litigation liabilities".

Other risks include unresolved environmental contamination or potential product recalls. Conducting legal due diligence, obtaining Phase I environmental reports, and reviewing customer complaints can help identify these issues early.

Contract Obligations

Hidden contract terms can disrupt your deal. For example, related-party agreements with vendors or customers tied to the seller's friends or family might feature below-market terms that won’t transfer to you. Change-of-control clauses in major contracts could result in penalties or even contract termination. Undisclosed intellectual property (IP) licensing or co-ownership agreements might leave you without the rights needed to operate the business. Carefully reviewing vendor, supplier, and lease agreements is crucial to uncover these clauses before finalizing the deal.

Employee-Related Obligations

Employee-related liabilities can lead to unexpected costs. These might include backdated compensation agreements, undisclosed bonuses, or verbal promises of benefits. Misclassified contractors and unpaid overtime claims are also common issues. To mitigate these risks, review benefit obligations, payroll records, and employment contracts. Conducting thorough HR audits can also reveal hidden commitments that could affect your bottom line.

How Sellers Hide Liabilities

Sellers often use deceptive tactics to hide liabilities and inflate the value of their businesses. Knowing these tricks can help buyers spot potential issues during due diligence and avoid costly surprises after the deal is done. Let’s dive into some of the most common methods sellers use to disguise liabilities.

Altering Financial Statements

One of the most common ways sellers conceal liabilities is by manipulating financial statements. For example, some sellers underreport labor costs by paying employees in cash “off the books.” This tactic hides payroll taxes and workers’ compensation obligations. In one case from March 2025, Matt Remuzzi, founder of CapForge, uncovered a moving company that concealed nearly 50% of its labor costs through off-the-books payments. This fraud came to light when physical work schedules and customer counts were compared to official payroll records.

Another frequent trick is reclassifying regular operating expenses - like maintenance and repairs - as capital expenditures to artificially boost EBITDA. Rajiv Tarigopula of Snowy Owl Capital highlighted a case where a seller inflated EBITDA by categorizing routine online ad keyword testing as “one-time R&D” costs. Sellers may also inflate their numbers by omitting allowances for bad debt, overstating obsolete inventory, or ignoring accounts payable and pending legal settlements.

These tactics go beyond simple number manipulation, as some sellers restructure their operations to obscure liabilities.

Creating Off-Balance Sheet Arrangements

Off-balance sheet arrangements are another way sellers hide liabilities. By using Special Purpose Entities (SPEs) or joint ventures, sellers can shift debt and risky investments into separate legal entities. Historically, public companies carried over $1 trillion in off-balance-sheet financing for leasing obligations before regulatory changes addressed the issue.

Sellers may also use related-party agreements or side contracts, such as discounted inventory sales or undisclosed vendor rebates, which conveniently disappear after the business changes hands. In some cases, sellers even create fake vendor invoices to make it seem like working capital is tied up when it isn’t.

These off-balance-sheet tactics are often paired with strict control over what information buyers can access.

Controlling Information in Data Rooms

Sellers often manipulate the data room process to downplay risks. For instance, they may omit details about active lawsuits, regulatory investigations, or environmental risks from disclosure schedules. Important liabilities, like liens on machinery or real estate, might only surface after the deal closes during Uniform Commercial Code (UCC) searches. When sellers do disclose issues, they may use vague terms like “pending claims” without providing details about amounts or involved parties, leaving buyers in the dark.

"The buyer will want to be sure that any liability arising during the period before the sale will be properly paid for prior to sale or reserved against the seller." - GRF CPAs & Advisors

By controlling the flow of information, sellers make it harder for buyers to assess the true extent of liabilities.

Manipulating Timing Before Closing

Timing manipulation is another tactic that can distort a business’s financial picture. For example, sellers might record future revenue in current statements while deferring related expenses, or delay recurring payments - like software renewals or maintenance fees - until after the sale. Another common strategy is channel stuffing, where sellers push customers to make early purchases or accept unnecessary goods to create a temporary revenue boost.

A high-profile example of timing manipulation occurred between 2013 and 2017 at Roadrunner Transportation Systems. The company systematically shifted expenses across quarters and avoided writing down uncollectible receivables, leading to fraudulent financial statements. Former CFO Peter Armbruster was sentenced to 24 months in prison for securities fraud. Additionally, sellers might pay off debts owed to insiders or family members just before presenting financial statements, further masking liabilities. These timing tricks can significantly skew a business’s valuation, with errors of 20% to 30% often going undetected during the acquisition process.
