How to Close a Business: 8 Obligations That Outlast the Last Sale

A business closes several times before it has finished closing. The register stops on one date, the last employee leaves on another, and the federal tax account, which the IRS will not retire while a single return is missing, may remain open for a season after the lights are off.

The eight obligations below survive the last sale. Whether an owner personally answers for the company's debts is a separate question with its own page on this site; what follows are the duties a closing business owes to its employees, to three kinds of tax authority, to the state that chartered it, to its landlord, and to the public record.

1. Final Payroll Arrives First and Brings Its Own Forms

Employees are paid before anything else is wound down, and the IRS closing checklist sets out the paperwork that follows the last paycheck: Form 941 (or 944) for the quarter in which final wages were paid, W-2s for the calendar year of those wages, and Form 940 for the same year. Payments to independent contractors are reported on Form 1099-NEC.

The withheld portion of those final wages deserves particular attention. Money withheld from paychecks is held in trust for the government, and an owner who lets it go to a supplier during the final weeks can meet it again later as a personal penalty.

2. A Large Enough Closing Owes Notice Before It Happens

Federal law asks for warning, not merely payment. Under 29 U.S.C. 2102, a covered employer may not order a plant closing or mass layoff until 60 days after serving written notice on the affected employees or their representative, on the state's rapid response unit, and on the chief elected official of the local government.

Coverage turns on size. The federal statute reaches employers with 100 or more employees, excluding part-time workers, or 100 or more who together work at least 4,000 hours a week; a plant closing means a shutdown at a single site that causes an employment loss for 50 or more full-time employees in any 30-day period.

New York's version is stricter. Its Labor Law article 25-A covers businesses employing 50 or more full-time workers, treats a single-site shutdown affecting 25 or more full-time employees as a plant closing, and requires notice at least ninety days before the order takes effect.

Ninety days before the doors close, in other words, the covered New York employer must already have said so in writing. That timing sits uneasily with the way most closings are actually decided, which is late, under pressure, after a lender declines to renew or a funder begins debiting an account that cannot bear it, and it collides with an owner's instinct to keep the news quiet until the last creditor has been paid, as though silence were a form of solvency. The statutes contain exceptions for circumstances an employer could not foresee. Whether one applies to a particular closing is a question for employment counsel, and not one to answer from hope.

Smaller employers fall outside both statutes. They still owe final wages on the schedule state law sets.

3. The Final Income Tax Return Follows the Entity Type

A sole proprietor reports the final year on Schedule C with the individual return. A partnership files Form 1065 and checks the final return box; an S corporation files Form 1120-S and checks the final K-1 box. A corporation that adopts a resolution or plan to dissolve must also file Form 966, and a business that sells its assets reports the sale on Form 8594, with Form 4797 for business property sold or exchanged.

These returns close the income tax year. They do not close the account.

4. Sales Tax Runs on a Twenty-Day Clock in New York

The New York Tax Department's bulletin on final sales tax returns requires a vendor that ceases operations, sells the business, or changes its form to file a final return within 20 days and to surrender or destroy its Certificate of Authority. A vendor that stops filing without a final return may be billed penalties for returns it never filed.

A closing that includes a sale of assets adds two steps: the seller gives the purchaser Form TP-153 and remits sales tax on the assets sold, and the purchaser files a bulk sale notice at least ten days before paying or taking possession. Other states run their own versions of this sequence.

5. The EIN Account Stays Open Until the Returns Are In

Closing the federal account requires a letter to the IRS in Cincinnati giving the business's legal name, EIN, address, and the reason for closing. The IRS states the condition plainly: it "cannot close your business account until you have filed all necessary returns and paid all taxes owed."

The state dissolution filing is a different act, made to a different government, and it does not substitute for this letter.

6. Creditor Notice Is Optional, and Often Worth Choosing

A dissolving corporation can ask the law to set a finish line. New York's Business Corporation Law section 1007 allows it to publish a notice at least once a week for two successive weeks in a county newspaper, mail copies to known creditors, and require claims in writing by a date no earlier than six months after first publication. Claims that miss the date are barred against the corporation, its assets, and its directors, officers and shareholders, subject to limited exceptions, and tax and government claims are excepted.

Delaware's sections 280 through 282 work on a shorter clock (a claim deadline no earlier than 60 days from the notice, published once a week for two consecutive weeks) and add a mechanism for contingent claims, under which the corporation offers security and may ask the Court of Chancery to fix an adequate amount. Directors who follow the procedure are shielded from personal liability for claims, and a stockholder's exposure is capped at the lesser of a pro rata share of the claim or the amount distributed to that stockholder.

But these statutes were written for corporations, LLCs have their own provisions, and nothing in either procedure releases a personal guaranty an owner signed. The notice closes the company's door to late claims. It leaves the owner's door exactly where it was.

7. The Lease Continues After the Business Does

A commercial lease runs to its stated term regardless of whether the tenant still trades. Returning the keys communicates intent; it does not end the obligation unless the landlord accepts a surrender, and that acceptance belongs in a signed document.

The security deposit, the condition of the premises, and any guaranty attached to the lease should all appear in the same agreement.

8. Liens and Records Are the Last Things to Leave the Building

A paid lender's financing statement can remain on the public record long after the debt is gone. Under the uniform text of UCC 9-513(c), once the secured obligation is satisfied and no commitment remains, the secured party has 20 days from the debtor's authenticated demand to see that a termination statement is sent or filed, and the uniform 9-625(e) allows the debtor to recover $500 from a party that fails to do so, on top of any actual loss it caused. Make the demand in writing. New York's enacted wording controls there and should be checked by counsel.

Records outlast the liens. The IRS asks that employment tax records be kept for at least four years, and a closed business will want its contracts, settlement releases, and bank statements for at least as long, stored somewhere an owner can find them after the office itself has been let to someone else. A banker's box in a relative's basement will do.

An Unpaid Advance at the Closing Table

A closing business often carries a merchant cash advance that the final weeks of revenue could not retire. Delancey Street, which settles business debt and is not a law firm, offers a free, confidential review of that balance and brings in independently licensed counsel when a legal question surfaces. Some closings need a different professional. An LLC or corporation receives no chapter 7 discharge, and an entity with many creditors and few assets may be better served by bankruptcy counsel supervising an orderly liquidation than by any negotiation. The review is one conversation among the several a careful closing requires, and the last obligation on this list is usually the one an owner remembers only when a buyer's lawyer asks.
