IRS Bulk Sales Notice — Business Purchase with Tax Liability — Definition Glossary

Defined by Sarah Mitchell, CPA | Reviewed by: James Okafor, EA | Updated May 2026

Full Definition

When a business is sold as a going concern, the buyer may inherit the seller’s unpaid tax liabilities if proper procedures are not followed. The IRS “successor liability” rule (IRC Section 3505) holds that a buyer who pays the full purchase price directly to the seller — rather than reserving a portion to pay off the seller’s outstanding federal tax liens — becomes liable for the seller’s unpaid payroll tax debt up to the purchase price paid. To protect against this, business buyers should: (1) conduct tax due diligence by requesting IRS tax transcripts (Form 4506-C) and checking the county courthouse for filed federal tax lien notices; (2) obtain an IRS payoff letter (called a Payoff Statement) before closing; (3) include an escrow holdback for potential tax liabilities; and (4) direct a portion of the purchase price to the IRS to satisfy known liens. Buyers who unknowingly purchase a business with existing IRS liens can seek reimbursement from the seller, but enforcing that claim requires separate litigation.
