Tax liabilities and holdbacks in a sale
Federal and state law current as of September 2026 — verify with counsel.
In a cannabis business sale, unpaid taxes can follow the buyer. An equity purchase keeps every tax liability inside the company. An asset purchase leaves income tax with the seller, but state successor-liability and bulk-sale laws can make the buyer personally liable for the seller's unpaid sales and excise taxes. Deals manage this with tax clearance certificates, bulk-sale notices, a tax indemnity, and a holdback or escrow.
Key takeaways
- California requires a buyer of a business to withhold enough of the price to cover the seller's unpaid sales and use tax until a CDTFA clearance is produced; a buyer who does not is personally liable up to the purchase price (Revenue and Taxation Code 6811 and 6812).
- New York buyers file Form AU-196.10 at least 10 days before paying or taking possession; New Jersey and Illinois buyers file Form C-9600 or Form CBS-1 at least 10 business days before closing.
- The IRS generally has 3 years from filing to assess tax, 6 years where more than 25% of gross income was omitted, and no limit where no return or a fraudulent return was filed (IRC 6501).
- SRS Acquiom's 2025 study of more than 2,200 private deals found a median 12-month indemnity survival period, and nearly three in ten deals used a separate special-purpose escrow for matters such as taxes.
- A tax holdback should be sized to a quantified exposure schedule and released when the relevant assessment period or clearance is reached, not on an arbitrary date.
Which tax liabilities follow a cannabis business through a sale?
It depends first on structure. The full comparison is in asset sale vs membership-interest sale; the tax side looks like this:
| Liability | Equity purchase | Asset purchase |
|---|---|---|
| Federal and state income tax, including 280E assessments for past years | Stays in the company the buyer now owns | Stays with the seller, subject to liens and transferee rules |
| Sales, use and cannabis excise tax collected but not remitted | Stays in the company | Can pass to the buyer under state successor-liability or bulk-sale law |
| Payroll taxes | Stays in the company | Generally the seller’s, but some states extend successor rules to withholding and unemployment accounts |
| Recorded tax liens | Remain on company assets | Remain on the purchased assets until paid and released |
| Local cannabis business taxes | Stays in the company | Depends on the local ordinance |
Cannabis deals lean toward equity purchases more often than ordinary small-business deals, because keeping the licensed entity intact can simplify change-of-ownership approval. That choice means the buyer takes the entity’s whole tax history.
Why cannabis targets carry more tax exposure than most
- 280E makes tax bills large relative to cash. Operators short of cash sometimes fall behind on federal income tax, or use excise tax they collected as working capital. See 280E explained.
- Filing positions are aggressive. Expanded cost of goods sold, second-business claims and returns filed as though 280E does not apply have all lost in court. In Harborside the asserted deficiencies exceeded $29 million.
- There are more taxes. State excise, wholesale, potency and local cannabis taxes sit on top of sales tax. Rates are in cannabis excise and potency taxes by state.
- Cash handling weakens records. Reconciling tax returns to point-of-sale and track-and-trace data takes longer.
How long exposure lasts is set by the assessment period. Under IRC 6501 the IRS generally has 3 years after a return is filed, 6 years if more than 25% of gross income was omitted, and unlimited time if no return or a fraudulent return was filed. States have their own periods.
Successor liability and bulk-sale rules: four examples
Asset buyers often assume they leave the seller’s taxes behind. For sales and excise taxes, several large cannabis states say otherwise unless the buyer follows a procedure.
| State | Rule | What the buyer must do |
|---|---|---|
| California | Rev. and Tax. Code 6811 and 6812: the buyer must withhold enough of the price to cover the seller’s unpaid tax, or becomes personally liable up to the purchase price | Obtain a CDTFA certificate that nothing is due; a buyer who requests one in writing is released if CDTFA does not issue it or a notice within 60 days |
| New York | Bulk sale rules: the buyer can be liable for the seller’s unpaid sales and use tax, and the state can claim a first-priority lien on the assets | File Form AU-196.10 at least 10 days before paying or taking possession, whichever is first, and follow the department’s release or notice of claim |
| New Jersey | Bulk sale notification: closing without notice makes the buyer responsible for the seller’s state tax debts | File Form C-9600 with the contract at least 10 business days before closing; hold the escrow amount the Division sets |
| Illinois | Form CBS-1: a buyer who does not give notice is personally liable up to the reasonable value of the property acquired | File at least 10 business days before the sale; comply with any bulk sales stop order |
Other states have their own versions. Build the notice period into the LOI-to-close timeline; these filings cannot be done the day before closing. Because cannabis closings are often conditional on regulator approval months later, confirm whether the clearance will still be current on the actual closing date and refresh it if not.
Tax diligence checklist for buyers
- Federal and state income tax returns for all open years, with the workpapers showing how cost of goods sold was computed.
- IRS and state account transcripts, not just the returns, to confirm what was actually paid.
- Excise and sales tax returns reconciled monthly to point-of-sale and track-and-trace sales data.
- Lien searches at the county, the secretary of state and any state tax lien registry. Priority rules are in tax-lien priority in cannabis sales.
- Audit notices, payment plans, offers in compromise and correspondence with any tax agency.
- Any refund claims or returns filed on the position that 280E does not apply, with the supporting opinion.
- Payroll tax filings, and worker classification for trimmers, drivers and brand ambassadors.
- Local cannabis business tax filings and the local licence’s good-standing status.
How holdbacks and escrows are sized
A holdback is part of the price the buyer keeps, or a third-party escrow agent holds, until specified risks pass. Sellers should expect one; the negotiation is over size, duration and release terms.
For general private-company deals, SRS Acquiom’s 2025 Deal Terms Study of more than 2,200 acquisitions reports a median 12-month survival period for indemnity claims, and says nearly three in ten deals carried a separate special-purpose escrow for stand-alone matters such as taxes or litigation. Cannabis deals usually need that separate tax escrow, and need it to run longer than 12 months.
Illustrative sizing. A $3,000,000 equity purchase of an adult-use retailer:
| Exposure | Amount | Likelihood the parties agree on | Weighted |
|---|---|---|---|
| Unremitted excise tax identified in diligence | $85,000 | Paid from proceeds at closing | Not escrowed |
| Cost of goods sold position on three open federal years | $240,000 tax plus $60,000 penalties and interest | 50% | $150,000 |
| State sales tax audit in progress | $70,000 | 60% | $42,000 |
| Payroll classification | $40,000 | 25% | $10,000 |
| Indicated tax escrow | $202,000, about 6.7% of price |
Known, liquidated amounts are paid at closing. Contingent amounts are escrowed. The percentages are negotiated judgments, not statistics.
Other tools used alongside a holdback
- Tax indemnity with its own survival period. Tax representations typically survive until the assessment period ends rather than the general 12 months. See reps, warranties, and compliance indemnities.
- Set-off against a seller note. Where the seller is financing part of the price, the buyer’s right to deduct indemnified tax losses from note payments works as a second holdback. See seller financing.
- Payoff at closing. Liens and agreed arrears are paid directly from proceeds through the closing agent, with releases delivered at closing.
- Pre-closing tax periods clause. Allocates responsibility for the straddle period and controls who runs any audit of pre-closing years.
- Staged release. For example, one third when state clearances arrive, one third at 18 months, the balance at 36 months if no audit is open.
Sellers can shrink the holdback by arriving with transcripts, clearances requested, and delinquent balances already on a payment plan; selling with tax delinquency covers that situation. This page is general education, not legal or tax advice.
Frequently asked questions
If I buy only the assets of a dispensary, can I still be liable for the seller's unpaid taxes?
Yes, for certain state taxes. Many states make the purchaser of a business or its stock of goods liable for the seller's unpaid sales, use and sometimes excise taxes unless the buyer follows a notice or clearance procedure. California, New York, New Jersey and Illinois all work this way. Federal and state tax liens recorded against the assets also survive the transfer unless they are paid and released at closing.
What is a tax clearance certificate and who gets it?
It is a written statement from a state tax agency that a seller owes no tax, or a statement of the amount that must be paid or escrowed. Depending on the state, either the seller requests it or the buyer triggers it by filing a bulk-sale notice. In California a buyer who requests a CDTFA certificate in writing is released if the agency does not respond within 60 days.
How large should a tax holdback be in a cannabis deal?
There is no standard percentage. The defensible approach is to build a schedule of specific exposures, such as unremitted excise tax, open audit years, aggressive cost of goods sold positions and penalties, put a dollar figure and a probability on each, and hold back an amount the parties agree covers the realistic total. Where exposure is large relative to price, buyers often use a seller note with set-off rights as well.
How long does a tax holdback usually last?
General indemnity escrows in private deals commonly run about 12 months, but tax exposure lasts longer. The federal assessment period is generally three years from filing and six years for a substantial omission of income. Parties often negotiate a staged release: part after state clearances arrive, part after a fixed period, with tax representations surviving until the assessment periods expire.
Does a state regulator check tax compliance before approving a cannabis ownership change?
Many do in some form. Cannabis regulators commonly require licensees to be in good standing with state tax authorities, and some require a tax clearance or certificate of good standing with a transfer or renewal application. Treat tax clearance as a regulatory closing condition as well as a financial one, and start it early because agency response times vary.
Can the seller's 280E audit become my problem after closing?
In an equity purchase it is the company's audit, so the company you now own pays any assessment and you rely on the seller's indemnity to recover it. In an asset purchase the assessment is against the seller, but a federal tax lien filed before closing attaches to the assets, and the IRS can pursue a transferee under section 6901 where assets were transferred for less than fair value.
