The seller’s unpaid sales tax can follow the assets.

In many states a statute makes the buyer of a business or its stock of goods liable for the seller’s unpaid sales and use tax. Your assumed liabilities schedule does not bind the state. Protection comes from a notice filed before closing and money withheld at closing. Pennsylvania’s version has no cap.

Can the state come after me for the seller’s unpaid sales tax after I buy the assets?

Yes. Successor liability statutes in many states make the buyer of a business or its stock of goods personally liable for the seller’s unpaid sales and use tax, usually up to the purchase price or the value of the assets acquired. That liability comes from the tax code, not your purchase agreement.

Sales tax is a trust-fund tax. The seller collected it as the state’s agent. If the seller kept it, the state’s collection statutes reach the assets and the buyer of them. Buying the equity instead does not fix this: the liability stays inside the entity you now own.

The mechanism repeats with local variations. The statute tells you to withhold enough of the purchase price to cover the seller’s tax until the seller produces a receipt showing payment or a certificate showing nothing is due. Fail to withhold and you are liable yourself. California and Texas say it in two sentences. Michigan uses no withholding language at all: it requires an escrow, and caps a buyer who did not escrow at fair market value less proceeds applied to superior secured interests. Read your state’s text, not the pattern.

Application: you close, you pay the seller in full, the seller pays its debts and moves. Eighteen months later the state assesses you for tax the seller collected before you owned anything. You have a contract right against a seller with no money, and no defense against the state. You pay twice.

What are the three separate tax exposures a buyer confuses into one?

Buyers treat sales tax in an asset deal as one problem. It is three, with three statutes and three filings. Successor liability for tax the seller already owes is one. Tax on the transfer of the assets themselves is two. The bulk sales notice that still survives under UCC Article 6 in a few places is three.

One. Successor liability is the live exposure, and in several states it is not confined to sales tax. Illinois runs the same machinery under its income tax act for withheld payroll tax. Pennsylvania is broader: an entity transferring fifty-one percent or more of specified assets must give the Department of Revenue ten days’ notice, and a purchaser who fails to require a clearance certificate is liable for the seller’s taxes through the transfer date, whether or not settled, assessed, or determined. Two things cut against you there. The text does not cap that exposure at the purchase price, and Commonwealth Court has held that a purchaser who skipped the certificate cannot then contest the assessment made against the seller. Note the entity words: a sole proprietor seller sits outside 1403(a).

Two. The transfer itself may be taxable, and assuming an exemption is not an answer. Do not assume your state has an occasional or isolated sale exemption, or that it covers this transfer. New York’s rule runs the other way: the purchaser is liable for sales tax on taxable tangible personal property included in a bulk sale. Titled items usually carry their own tax at retitling. Get the answer in writing before you sign the allocation schedule, because the tax is often measured by the value allocated to tangible property.

Three. UCC Article 6 is mostly dead, repealed in most states after the Uniform Law Commission recommended it. Division 6 of California’s Commercial Code survives, applying only where the seller’s principal business is selling inventory from stock, restaurants included, and excluding sales whose asset value is under ten thousand dollars or over five million. Before relying on repeal elsewhere, confirm that state’s current bulk transfer title rather than a secondhand list of dates. Complying does nothing about the tax exposure above.

Law: 72 P.S. 1403(a); 43 P.S. 788.3(a); 35 ILCS 5/902(d); 20 NYCRR 537.1, 537.4(b); Cal. Com. Code 6101 et seq., esp. 6102 and 6103.

What does the buyer have to file, and how long does the state get to answer?

In the states with a purchaser notice form, the buyer files: New York, New Jersey, Illinois. Lead times run in days before you pay or take possession. The state then gets a statutory window to answer, and you withhold until the receipt, the certificate, or the window expires. File late and you generally lose the protection.

Law: N.Y. Tax Law 1141(c), 20 NYCRR 537.2, 537.3(c), 537.4(c), 537.6(d); N.J.S.A. 54:50-38 and Form C-9600 guidance; 35 ILCS 120/5j, 86 Ill. Admin. Code 130.1701; Cal. Rev. & Tax. Code 6811, 6812(b), (c); Tex. Tax Code 111.020(a) to (f); RCW 82.32.140(2), (4), WAC 458-20-216; Mich. Comp. Laws 205.27a(1); 72 P.S. 1403(a).

Two features drive the deal. The lead times run backward from closing, into your signing-to-closing period. And several states give a release date unconnected to any certificate. Each window is a duty on the agency, not a promise about speed, so let the escrow release when the window runs.

Why is withholding a signing-to-closing item and not a post-closing cleanup?

Because withholding is a remedy that exists only while you still hold the money. The statutes tell you to hold back part of the purchase price until the receipt or certificate arrives. Pay the seller in full and there is nothing left to withhold. A few states let a later filing start a clock; most do not.

The exceptions are narrow. Washington’s six months runs from the later of the Department’s receipt of your notice or your succession, so notice after closing still starts the clock, and California and Texas let you request the certificate after the sale. None of it recovers money already wired. So sequence the work: notice goes out during diligence, the escrow is negotiated with the purchase agreement rather than bolted on at closing, and the seller’s confidentiality waiver is signed at signing, because in Michigan that waiver lets the department disclose the number.

The state is not a party to your purchase agreement. It never agreed to your indemnity cap or your survival period, and at this size the indemnity usually has nothing funded behind it.

How do you close on an SBA 7(a) timetable when clearance can take months?

You structure around the state’s calendar, because you cannot compress it. A clearance certificate can require the state to examine the seller first. Your closing runs on lender credit approval, the loan authorization, a lease assignment and proof of equity injection. The certificate often will not arrive first. Escrow instead of waiting.

Stated as of August 2026: SOP 50 10, the SBA’s operating procedure for the 7(a) program, is revised periodically, and your lender applies the version in force when your loan number issues. That includes standby terms on a seller note. Confirm the current version and your lender’s requirements rather than treating any summary, this one included, as permanent. No SOP makes a revenue department move faster.

Three structures, in order of how well they protect you.

• A defined escrow, sized to the estimated exposure. Fund it from the seller’s proceeds at closing. Size it from the state’s own figure where the statute gives you one, filed returns against reported revenue, and nexus where the seller shipped but never registered. Draft two release triggers: the receipt or certificate, or the running of that state’s window.
• A right of setoff against a seller note. Say in the purchase agreement that you may set off state tax assessments against the note. A note you have not yet paid beats a promise. Confirm the mechanics with your lender: a note credited toward your equity injection sits on standby, and standby forms can limit setoff.
• An indemnity alone. Weakest of the three. A seller who has paid off a mortgage and bought a retirement condo is not a collection target, and an indemnity from a dissolved LLC is paper.

Sometimes you will close without the certificate. That can be the right call. Make it a decision, not a drift: put the exposure, the reason for proceeding and the mitigation in writing, and keep the filings and the state’s responses in the closing file. Nobody can tell you what the state will assess, or when.

Will I inherit the seller’s unemployment insurance experience rate?

Sometimes, and it is a state statute question. Unemployment rates are experience-rated, and many state laws transfer the seller’s experience record to a buyer who acquires the trade or business. Transfer is mandatory where common ownership, management or control exists. Get the answer, and the rate, in writing before closing.

Federal law pushed every state to adopt mandatory transfer rules, but that mandate targets transfers between commonly owned or controlled businesses. For a purchase from an unrelated seller the answer sits in state law, and states differ: some transfer the record when you acquire the whole trade or business, some on joint application, some allocate when you buy part. Ask for the seller’s latest rate notice and claims history, then get the number from the agency in writing. Pennsylvania also runs a clearance certificate for unemployment contributions.

This one rarely blows up a deal. It quietly changes your model: a few points of payroll is real money against a debt service schedule, and it never shows in a trailing twelve months prepared at the seller’s rate.

Successor liability is a one-time bill you can escrow against. An inherited experience rate is a recurring cost you cannot.

What should I do this week to build the exposure grid and size the holdback?

Build a one-page grid before your next lender call. One row per state where the target has employees, inventory, property, or sales into the state. Six columns: the buyer’s filing, its statutory lead time, the state’s response window, the limit on your exposure, whether the transfer is taxable, and the unemployment answer.

• Confirm what the seller legally is; some of these statutes reach only entities.
• Pull registrations and filed returns for every state in the grid, across the full assessable period, and compare them against revenue by state. Gaps and unregistered states are where assessments live.
• Calendar every lead time backward from closing; give the earliest to your lender.
• Draft the escrow with both triggers and name the escrow agent in the agreement.
• Ask each unemployment agency for the successor rate determination in writing.

Then tell your lender the size of the holdback and where the money comes from. Lenders decide funding flows and the SBA sets its program terms, so the holdback has to work inside their requirements. Bring the grid, the statutes and the number.
