When buying a business, it's easy to focus on negotiating purchase price, drafting contracts, and planning post-acquisition strategy. One area that often catches even seasoned investors off guard is successor liability: the risk that a buyer inherits the seller's unpaid state taxes.
Tax clearance certificates from California’s state agencies protect business buyers from inheriting the seller’s unpaid taxes as successor liability. The key agencies: CDTFA (sales/use tax), EDD (payroll), FTB (income tax), and the county tax collector. Buyers should request clearance before closing and structure escrow to hold back the disclosed amounts. The 2025 SL Blue Garden decision sharpened the rules around CDTFA clearance specifically.
They're a non-negotiable closing checklist item.
Without tax clearance certificates from the CDTFA, EDD, FTB, and the county tax collector, a California business buyer can be held personally liable for the seller's unpaid sales, payroll, and income taxes, up to the full purchase price. A 2025 decision (Appeal of SL Blue Garden Corp.) confirmed that even relying on the escrow company to handle clearances is not enough. Let's get into the details:
Many U.S. states, including California, Texas, New York, and Pennsylvania, hold buyers responsible for sales, payroll, or income taxes owed by the seller unless specific clearance procedures are followed. Obtaining tax clearance certificates is the primary way to cut off this liability.
This article explains what tax clearance certificates are, why they matter to buyers, the legal framework in California (with references to relevant statutes and case law), and best practices for buyers in any state.
A tax clearance certificate (also called a tax or successor-liability clearance) is a document issued by a state tax authority certifying that a business has paid all taxes, or specifying the exact amount that must be withheld from the purchase price. In California, the certificate is issued by:
Other states have similar processes: many require sellers to obtain clearance certificates or provide bulk-sale notifications 10 to 30 days before closing.
The certificate protects the buyer by proving that the seller has satisfied the relevant taxes, or by informing the buyer how much to withhold from the purchase price and remit to the state. Without it, the buyer may be liable for the seller's unpaid taxes even if the contract explicitly allocates taxes to the seller.
Successor liability means that a purchaser of a business, or of a substantial portion of its assets, can be held responsible for the seller's unpaid taxes even if the buyer didn't know about them.
California's Sales and Use Tax Regulation 1702 requires a buyer to withhold enough of the purchase price to cover any outstanding sales-tax liabilities, including penalties and interest. If the buyer fails to withhold, they become personally liable up to the amount of the purchase price. The CDTFA can enforce this liability by issuing a notice of successor liability within three years of being notified of the sale.
Similar rules apply for payroll taxes under California Unemployment Insurance Code §§ 1731–1733. When a buyer acquires an employer's business, they must withhold enough money or property to cover the employer's payroll-tax liability until the seller produces an EDD clearance certificate. The EDD must issue a statement of amounts due within 30 days of the buyer's request; failure to do so releases the buyer from liability. If the buyer does not withhold or pay the amount due, the buyer becomes personally liable up to the purchase price.
Across states, successor-liability statutes vary. Some require buyers to notify the state and withhold funds until they receive clearance; others provide relief if buyers secure clearance certificates or comply with bulk-sale procedures. Regardless of the state, failing to obtain clearance exposes buyers to audits, penalties, and the risk of paying taxes twice, once in the purchase price and again to the state.
A recent California decision illustrates the pitfalls of neglecting clearance. In Appeal of SL Blue Garden Corp. (2025-OTA-209), the buyer purchased a restaurant without requesting a CDTFA tax-clearance certificate. After closing, the CDTFA issued a Notice of Amount Due for unpaid sales taxes. The buyer argued that the escrow company had requested the certificate and that the seller was still being pursued.
Nevertheless, the CDTFA held the buyer liable because they did not request the certificate before closing or withhold enough funds to cover potential taxes. This case underscores that a buyer can be held liable even if the escrow company or seller fails to notify the tax authorities.
The primary reason to obtain clearance certificates is to avoid unknown tax liabilities. Tax clearance certificates confirm that payroll, sales, income, and property taxes are settled before closing, protecting buyers from inheriting the seller's debts. Without clearance, buyers can unknowingly inherit thousands of dollars in unpaid taxes, lenders may refuse to fund the deal, and escrow officers may refuse to close.
In addition to protecting against sales and payroll taxes, the California FTB issues a buyer's withholding clearance certificate that confirms all withholding taxes have been paid and releases the buyer from further liability. However, this certificate only covers withholding taxes; buyers must still obtain clearances for sales, payroll, and property taxes.
Successor-liability statutes impose strict deadlines. Under California Revenue and Taxation Code § 6812, the CDTFA must issue a tax-clearance certificate or a notice of the amount due within 60 days after the later of:
If the CDTFA fails to issue a certificate or notice within that period, the buyer is released from the duty to withhold. The EDD has a similar 30-day period for payroll taxes.
These timelines create a safe harbor: once the buyer has requested clearance and the state fails to respond within the statutory window, the buyer's liability is cut off. But to trigger this protection, the buyer must make a written request for clearance. Oral requests or reliance on escrow are insufficient.
Because the seller's tax liabilities may not be known until the state reviews the seller's records, the law requires buyers to withhold part of the purchase price until clearances are issued. Regulation 1702 provides that the requirement to withhold arises when a business or stock of goods is sold under contract for a price in money or property. California Revenue and Taxation Code § 6812 specifies that a buyer who fails to withhold becomes personally liable for the seller's unpaid sales-tax liabilities.
The amount withheld must be sufficient to pay the seller's tax liabilities; if the withheld funds are insufficient, the state can pursue the buyer for the shortfall. For payroll taxes, the California Unemployment Insurance Code similarly requires buyers to withhold enough funds until the seller produces an EDD clearance certificate. If the EDD issues a statement showing an amount due, the buyer must pay it to the EDD (up to the purchase price).
Tax agencies have priority over most other creditors. During a bulk sale, the CDTFA, EDD, FTB, and county tax collectors have precedence over other debts. When there are insufficient funds to pay all of the seller's creditors, state tax agencies may receive payment before lenders or vendors. This is why escrow companies often hold back the entire purchase price until all tax clearances are issued. If the buyer fails to obtain releases, agencies may pursue the buyer for unpaid taxes, and the buyer has little recourse to recover from the seller.
The CDTFA oversees sales and use taxes, and its clearance process is often the most involved. The CDTFA generally requires:
The CDTFA has 60 days to issue a certificate or notify the buyer of the amount due. If the certificate is not obtained before closing, the buyer must withhold sufficient funds and may need to negotiate indemnity provisions with the seller.
The EDD handles payroll and employment taxes. Under California Unemployment Insurance Code §§ 1731–1733:
EDD clearance is particularly important in industries that rely on independent contractors (salons, trucking, cleaning services). The EDD may conduct an audit if the seller reports having no employees to ensure payroll taxes were properly paid.
The FTB issues a buyer's withholding clearance certificate, also known as a bulk-sale certificate, for income-tax withholding. Buyers must submit a written request online, by fax, or by mail. If the seller owes no withholding taxes, the FTB will issue the certificate and release the buyer from withholding liability. However, this certificate only applies to withholding taxes; it does not release the buyer from liability for sales or payroll taxes.
For business personal-property taxes, many California counties require sellers to obtain a clearance from the county tax collector. The county verifies that property-tax assessments on equipment and fixtures are current. Even a small outstanding balance can delay escrow. Buyers should ensure that county taxes have been paid and should obtain written proof before closing.
While the specifics above are California-centric, buyers in other states face similar requirements. Failure to obtain a tax clearance certificate or bulk-sale release is the most common trigger of successor liability nationwide. Many states require notification to the tax authorities 10 to 30 days before a sale; some demand bank information for the escrow account and an affidavit from the seller that no tax is due.
Some states, including Pennsylvania, Michigan, New York, and Texas, explicitly require buyers to secure clearance certificates or bulk-sale releases to avoid being liable for the seller's unpaid sales taxes. States may require only a simple letter, while others have forms and defined periods for notification. Buyers generally must withhold a portion of the purchase price until liabilities are paid or clearance certificates are issued.
When clearances cannot be obtained, because the seller has never filed returns or owes material taxes, buyers should consider voluntary disclosure agreements (VDAs) or other indemnification arrangements.
Tax clearance certificates are more than paperwork, they are a crucial shield against hidden tax liabilities when buying a business. California law, and the laws of many other states, impose successor liability on buyers who fail to withhold the purchase price or obtain clearances. Certificates from the CDTFA, EDD, FTB, and county tax collectors confirm that the seller has paid required taxes or specify the amount to be withheld. Without them, buyers may face unexpected tax bills, penalties, and litigation.
The good news is that buyers can protect themselves. By requesting clearance certificates early, withholding funds, conducting thorough due diligence, and working with experienced professionals, buyers can close transactions confidently and avoid inheriting the seller's tax burdens. In multi-state deals, engage experienced multi-state tax counsel who understand each state's rules and consider voluntary disclosure agreements or tax insurance for additional protection.
Above all, treat tax clearance certificates as a non-negotiable part of your closing checklist, because the cost of overlooking them can far exceed the effort required to obtain them.
