How to Close a Small Business: 7 Steps for a Sole Proprietorship or Partnership

Shutting a failing business is not as simple as flipping the sign on the door from “Open” to “Closed.” That won’t get rid of obligations to landlords, employees, suppliers and lenders. Closing your sole proprietorship or partnership is a multi-step process, and many are difficult, even in normal times. That’s doubly true when you’re in debt or your business has flopped. Your first job is to sit down with your partners, if you have any, and decide together that this is what you all want to do. Then you need to pick a closing date. Next, you’ll deal with employees (you might not have any). You’ll have to pay off debts, settle your final tax returns, close up your bank accounts, and put your business records into cold storage.

Unincorporated enterprises are made up of all the people involved: one person and you get a sole proprietorship. A sole proprietor has the final say on whether or not they will close. Several people and you get a partnership, and those people will have to agree they want to close their partnership. And it pays to write that down. Keep a record.

You, and your partners if you have them, must agree on what the business’ ”closing date” is going to be, meaning the date that you’re officially closed to business. What are you doing with your remaining supplies and assets? The wind up will involve paying outstanding debts such as taxes, debts to suppliers, utilities, possibly refunds to customers, while other resources such as buildings, furniture, machinery can be sold to pay debts.

Notice of a Closure to Employees

Tell employees of plans to close the business as soon as you’ve made them. If you wait, they’ll find out from someone other than you. That’s never good. There are specific requirements under the WARN Act if you have 100 or more full-time employees. The federal WARN Act requires employers to provide 60 days’ written notice of a closure to employees, and various state and local government officials.

You’ll file a final Form 941 (or 944), check the box that says your business has closed, and be sure to give your employees their W-2s, by the return’s due date. Form 1099-NEC is for contractors you paid $2,000 or more in 2026. It used to be $600. Watch those withheld payroll taxes. The IRS calls these taxes ”trust fund” taxes, and the agency is serious about getting them back. If the government isn’t paid this, whoever was responsible and willfully didn’t pay, even a partner, can be held personally liable for 100% of the trust fund tax.

Receivables are worth money. You need to collect receivables from customers who owe you money. Tell customers about unfinished orders. Prepaid orders need to be accounted for. Take care of refunds and deposits. Tell vendors and suppliers to stop shipments. Keep a mailing address.

Of course, you could have any number of creditors. These include government agencies, any lease holders and landlords, suppliers, utility providers, anyone who has loaned you money or given you a loan or lease or otherwise extended you credit. Let them know you’re closing the business. You’ll also need to pay taxes due, payroll and wages earned, credit cards, leases, and any vendor goods received that haven’t been paid for. Shutting down your business will generally not free you from a personal guarantee if the company cannot pay. In a limited partnership, the general partner has unlimited liability, while the limited partners have limited liability.

If you’re unable to pay all your bills at once, you’ll have to decide which debts to pay first, and then second, and then third. There are fairly strict rules about this, such as paying wages, payroll taxes, and secured debts to banks with liens on property. Don’t forget you may have a commercial lease or other obligations that continue past the closing date. You can’t just walk out and forget about it.

Generally, if you settle or cancel a debt for less than the amount you owe, the amount the creditor forgives is taxable income to you that year, unless the bankruptcy or insolvency exclusion applies, and that exclusion is claimed on Form 982.

Final Returns

A sole proprietorship doesn’t file a return on its own. It is filed along with the owner’s personal tax return, Form 1040. If you’re running a sole proprietorship, report your final year’s income and deductions on Schedule C. Also file Schedule SE if your net earnings from self-employment are $400 or more.

To report the closure of a partnership, file a final Form 1065. Be sure to check the final return box on the form, and the final K-1 box on each partner’s Schedule K-1. The partnership’s tax year ends on the day it terminates. Its Form 1065 is generally due by the fifteenth day of the third month after the termination. The partnership is subject to a penalty for every month the return is late, that being $255 multiplied by the number of partners, for up to 12 months, on 2025 returns filed in 2026.

Make sure to close out any business accounts and give up the rights to your business name. Cancel any type of permits and licenses you or the business had before closing. Reconcile the bank account before closing. It pays to leave enough in the account to cover outstanding checks, taxes, refunds, service charges, and other expenses the account may still accrue. Once the bank account is closed, you will want to get written confirmation that the account has been closed.

To close your business account with the IRS you need to mail them a letter with the legal name of the business, its EIN, the business address, and the reason it is closing. The IRS won’t close the account until all tax returns are filed and all taxes paid.

Keep some records after closing. The IRS says you should keep your employment tax records for at least 4 years. You also want to keep final returns, releases, creditor notifications, and proof that all accounts were closed.

How long it takes to close a company depends on how many filings you have to do, how many tax accounts there are, how many employees there are, the status of creditors, and any contracts, leases or other agreements to cancel. Not to mention unresolved partner disputes. There’s no one deadline or end date.
