How to Structure an Asset Purchase Agreement (APA) vs. Stock Purchase Agreement (SPA) in Illinois

Current as of: September 21, 2026 Mergers & Acquisitions (M&A) Illinois
When buying or selling a business in Illinois, you generally must choose between an Asset Purchase Agreement (APA) and a Stock Purchase Agreement (SPA). Buyers typically prefer an APA to gain significant tax advantages and avoid the seller's hidden liabilities, while sellers often favor an SPA for a cleaner exit.

Acquiring a business in Illinois is a complex legal and financial maneuver. Whether you are buying a popular restaurant in Chicago, a manufacturing plant in Peoria, or an IT firm in Naperville, the transaction's legal structure will dictate your tax burdens and your exposure to future lawsuits. The two primary structures for M&A (Mergers and Acquisitions) deals are the Asset Purchase Agreement (APA) and the Stock Purchase Agreement (SPA).

Understanding the fundamental differences between buying the physical and intangible assets of a company versus buying its legal equity (shares or LLC membership interests) is critical. A poorly structured deal can leave a buyer on the hook for the seller's unpaid taxes, pending litigation, and broken contracts. Engaging a local corporate attorney from our directory early in the process ensures you select the structure that best protects your investment.

Structuring the Deal: Asset Purchase vs. Stock Purchase

The choice between an APA and an SPA involves balancing tax benefits, liability risks, and administrative hurdles. Here is a breakdown of how these structures function under Illinois corporate law.

When to Choose an APA for Tax Benefits in IL

In an Asset Purchase Agreement, the buyer purchases individual assets (equipment, customer lists, goodwill, inventory) rather than the company itself. Buyers heavily favor APAs because they provide a 'step-up' in basis. This means the buyer can depreciate the purchased assets at their current fair market value, rather than the seller's depreciated book value. Additionally, under the federal tax code, buyers can amortize intangible assets like goodwill over 15 years (known as 26 U.S.C. § 197 intangibles). This creates massive tax deductions for the new owner that are not available in a standard stock purchase.

Avoiding Hidden Successor Liabilities in SPAs

A Stock Purchase Agreement means you buy the actual legal entity (the Corporation or LLC). By stepping into the seller's shoes, you acquire all the company's assets, but you also inherit all of its liabilities. If the company is sued for a product defect that occurred three years ago, or if it has unpaid employment taxes, the new owner is fully responsible. In contrast, an APA generally allows the buyer to leave the seller's liabilities behind. However, Illinois courts recognize exceptions to this rule. In Vernon v. Schuster, 179 Ill. 2d 338 (IL Supreme Court 1997), the court established that a buyer can still be held liable in an asset purchase if the deal is deemed a 'de facto merger' or a fraudulent attempt to escape debts.

How the Illinois Bulk Sales Law Impacts Asset Purchases

While APAs protect you from many liabilities, they trigger the strict requirements of 35 ILCS § 120/5j. If you buy the majority of a business's assets outside the ordinary course of business, you must formally notify the state by submitting Form CBS-1, Illinois, Department of Revenue, Notice of Sale, Purchase, or Transfer of Business Assets. Failing to comply means the Illinois Department of Revenue, Chicago can hold you, the buyer, personally liable for the seller's unpaid sales, use, and income taxes. Submitting this form ensures you obtain required tax clearance before closing funds are fully released to the seller.

Transferring Permits and Licenses in Illinois

One major drawback of an APA is that contracts, permits, and licenses do not automatically transfer to the buyer. If you are buying a bar in Chicago, the liquor license must be completely reapplied for. If you are buying a manufacturing facility, environmental permits must be transferred through the Illinois Environmental Protection Agency, Springfield. In an SPA, because the legal entity remains exactly the same, most permits, vendor contracts, and leases remain intact (unless they contain specific 'change of control' clauses), making the transition significantly smoother.

How Much Does Structuring an M&A Deal Cost?

Corporate legal fees vary based on the size and complexity of the transaction. For a standard small-to-midsize business acquisition in Illinois, buyers can expect to pay:

  • Due Diligence & Drafting: Attorneys typically charge $300 to $600 per hour. A complete APA or SPA for a $1M to $5M business usually costs between $15,000 and $40,000 in legal fees.
  • State Filing Fees: Filing amended Articles of Incorporation or LLC updates with the Illinois Secretary of State, Springfield requires a base statutory fee of $50 under 805 ILCS 5/15.10(b) and 805 ILCS 180/50-10(b) ($150 applies for restated articles or initial entity formation, while expedited processing adds $100).
  • CPA Fees: Hiring a local accountant to conduct financial due diligence and advise on the tax allocation of the purchase price generally costs $5,000 to $15,000.

How Long Does a Business Acquisition Take?

From the moment a Letter of Intent (LOI) is signed, a standard business acquisition in Illinois takes about 60 to 120 days to close. The timeline is heavily dictated by the due diligence process. If you choose an APA, you must factor in additional time (often 30 to 45 days) to secure third-party consents from landlords, vendors, and state agencies for the transfer of licenses and contracts.

Frequently Asked Questions (FAQ)

Can I force a seller to accept an Asset Purchase?

You cannot force a seller, but you can negotiate. Buyers often pay a slightly higher purchase price in an APA to compensate the seller for the heavier tax burden they will face compared to a stock sale.

What is a 'Change of Control' provision in an SPA?

Even though an SPA transfers contracts automatically, some commercial leases and vendor contracts contain 'Change of Control' clauses. This means if the ownership of the company changes hands, the contract can be terminated. Your attorney must review all contracts for these clauses during due diligence.

Do employees automatically transfer in an APA?

No. In an Asset Purchase, the seller effectively terminates all employees on the closing date, and the buyer must formally re-hire the employees they wish to keep. In an SPA, employment continues uninterrupted.

Why do I need a lawyer if we already agreed on a price?

The purchase price is only one small part of the deal. A lawyer ensures you are protected from the seller's past debts, negotiates non-compete agreements, handles tax clearances, and correctly drafts the indemnification clauses to protect you post-closing.
