Closing a Business Takes More Than Stopping Sales

Most owners picture the last day of business as the day the final customer pays and the doors close. The IRS and the State of Florida do not see it that way. As far as they are concerned, your business stays open until every return is filed, every tax is paid, and every account is formally closed. I have watched owners lock up a shop or shut down a practice, then receive notices two years later for returns nobody told them were still due. This guide walks through the order I would take, written for someone who has never closed a business before.

Start by Knowing What Kind of Business You Have

Everything that follows depends on how your business was set up, so confirm that first. A sole proprietor owns an unincorporated business alone and reports it on Schedule C of a personal return. A partnership has two or more owners, and a corporation, including an S corporation, is its own taxpayer. A limited liability company is a state creation, and the IRS treats it as a sole proprietorship, a partnership, or a corporation depending on how it chose to be taxed. If you are unsure which category applies to you, check last year's tax return, because the form on top (Schedule C, 1065, 1120, or 1120-S) tells you the answer.

File the Final Income Tax Return

Every business must file a final return for the year it closes. On partnership, corporation, and S corporation returns, there is a box near the top of the first page, just under the name and address, marked as the final return. Check it, and if the return includes Schedules K-1, check the final K-1 box on each of those as well. Sole proprietors have no such box, because Schedule C simply gets filed with your personal return for the closing year. Sole proprietors with net earnings of $400 or more also file Schedule SE for self-employment tax.

A corporation has one extra step. If the owners adopt a resolution or plan to dissolve the corporation or liquidate any of its stock, the IRS requires Form 966, Corporate Dissolution or Liquidation. The form instructions give a deadline of 30 days after the resolution or plan is adopted, so this one should happen early rather than late. Taxable C corporations in Florida must also file a final state corporate return, Form F-1120. Ask your CPA to confirm the Florida filing requirement for your entity type before you close the books.

Take Care of Payroll Before Anything Else

If you have employees, payroll is the area where closing mistakes cost the most, so give it first priority. You must pay final wages and any compensation owed, then make your last federal tax deposits. Report them on Form 941 (quarterly) or Form 944 (annual) for the period in which the final wages were paid. On that form, check the box telling the IRS the business has closed, enter the date of the final wage payment, and attach a statement naming the person who will keep the payroll records and the address where they will be kept. You also file Form 940, the federal unemployment tax return, for the year you paid final wages, and you check box d to mark it as final.

Each employee needs a Form W-2 for the year of their final paycheck. The IRS says to furnish those to employees by the due date of your final Form 941 or 944, and you send Copy A to the Social Security Administration with Form W-3. If your employees receive tips, Form 8027 reports the final tip income. If you offered a retirement plan or a health savings account, those have their own termination steps, and the IRS keeps separate guidance for each. Florida also requires you to address your state reemployment tax account, which is the state unemployment tax, so do not skip it just because the federal forms are finished.

The reason I stress payroll is the Trust Fund Recovery Penalty. Income tax and Social Security and Medicare tax withheld from paychecks belong to the government from the moment you take them out. If those amounts go unpaid, the IRS can assess a penalty equal to the full unpaid amount against any responsible person, and that includes owners, officers, and anyone else with control over which bills get paid. The IRS states that paying other expenses instead of the withholding taxes is an example of acting willfully. Once the penalty is asserted, the IRS can pursue personal assets, and a corporation or LLC does not shield you from it.

Report What You Paid Your Contractors

People often forget the contractors, because they never appeared on payroll. If you paid an independent contractor for services during the year you close, you may owe that person a Form 1099-NEC and the IRS a copy. For payments made in 2026 and later, the reporting threshold is $2,000 per contractor, up from $600 for earlier years. The IRS Closing a Business page still shows the older $600 figure in its text, so confirm the threshold that applies to the year of your payments before you file. Payments to corporations are generally exempt, though payments to attorneys remain reportable even when paid to a corporation.

Close Your Florida Sales Tax Account

If you collected sales tax, the Florida Department of Revenue treats you as open until you tell them otherwise. The Department's guide for registered dealers says that if you cancel your account or sell your business, you must file a final return and pay all tax due within 15 days after closing or selling. That final return covers the period from your most recent filing through the closing date. Florida tax attorneys also warn that a closed business must keep filing, even with zero sales, until the account is formally canceled, and that a missed return carries a minimum penalty. I recommend filing the final return, marking it as final, and keeping the confirmation along with any written closure acknowledgment from the Department.

Deal With Outstanding Debts in the Right Order

Taxes come first, in my view, for a practical reason. The IRS will not close your business account until all required returns are filed and all taxes owed are paid, so unpaid tax balances hold up everything else. After that, list every vendor, lender, landlord, and credit card tied to the business, and contact each one in writing about the closing. If a creditor agrees to accept less than you owe, the forgiven amount is generally taxable income in the year of the cancellation, and the creditor may send you a Form 1099-C. You must report taxable canceled debt whether or not you receive that form, though exceptions exist for debt canceled in bankruptcy or while you are insolvent, and those are reported on Form 982.

One more rule belongs here. If a lender takes property that secured a loan in full or partial payment of the debt, the IRS treats that as a sale of the property for the amount of debt canceled, and you may have a taxable gain or loss. That surprises many owners who assumed that handing back equipment ends the matter. If you signed a personal guarantee on any business loan, speak with a CPA and an attorney before you negotiate, because the guarantee can keep you responsible even after the entity is gone.

Decide What Happens to the Remaining Assets

Equipment, vehicles, inventory, and furniture all need a plan. When you sell property used in the business, you report the sale on Form 4797, Sales of Business Property, and you file it for each year you sell or exchange business property. The same form applies if closing the business drops the business use of property you wrote off under Section 179 to 50 percent or less. If you sell the business itself as a going concern, Form 8594, the Asset Acquisition Statement, enters the picture. Whatever is left after debts are paid goes to the owners, and your final return should reflect that distribution along with any capital gains or losses on Schedule D.

Dissolve the Entity With the State

Stopping operations does not end the legal entity. In Florida, you file Articles of Dissolution with the Division of Corporations through Sunbiz. The current fee is $25 for an LLC and $35 for a profit or nonprofit corporation, and the Division says it takes two to three business days for the filing to post. Until that filing is accepted, the entity stays legally active. An LLC should check its operating agreement first, and if the agreement is silent, Florida's default rule requires the consent of all members.

Filing with Sunbiz does not clean up your tax accounts. The two are separate processes, which is why I like to finish the tax work first. Corporations should also notify known creditors and publish notice to unknown ones as part of winding up, so ask an attorney to confirm the steps for your situation. Once the dissolution posts, download the filed copy from Sunbiz, which costs nothing, and keep it with your closing file.

Cancel the EIN Last

Your employer identification number is permanent, so closing the IRS account takes a written request. Send a letter with the complete legal name of the business, the EIN, the business address, and the reason you want the account closed. If you still have the notice the IRS sent when it assigned your EIN, include a copy. Mail it to the Internal Revenue Service, Cincinnati, OH 45999. Do this only after every return is filed and every balance is paid, since the IRS will not close the account before then.

Keep Your Records Longer Than You Think

Closing the business does not close your exposure to an audit. The IRS says to keep records supporting income, deductions, and credits until the period of limitations for that return expires. That is generally three years from filing, six years if you left out income exceeding 25 percent of the gross income on the return, and seven years if you claimed a loss from worthless securities or a bad debt deduction. Employment tax records must be kept for at least four years after the tax is due or paid, whichever is later. Property records should stay until the limitations period ends for the year you dispose of the property.

Insurers, landlords, and lenders sometimes require longer retention than the IRS does, so check with them before you shred anything. I suggest a single folder, paper or digital, holding the final returns, filing confirmations, the dissolution papers, the EIN letter, payroll records, and a note on where everything is stored. Whoever you named in the Form 941 statement as the keeper of payroll records will need that folder. A tidy closing file is the best protection you have if a notice arrives years later.
