To close a sole proprietorship in Florida, you don’t file a dissolution with the state the way an LLC or corporation would. Instead, you unwind the business by paying off debts, canceling any fictitious name registration, closing your Florida tax accounts, filing final federal returns, and notifying every agency that issued you a license, account, or tax number. Because a sole proprietorship has no legal identity separate from you, missing a step can leave you personally on the hook for taxes, penalties, or claims tied to a business you thought was already closed.
Work through the steps below in roughly the order they appear. Some, like insurance tail coverage and lease notice, need to start weeks before your last day of business.
Settle Your Business Finances First
Pay off creditors, suppliers, and lenders. Collect outstanding invoices or write them off. Once receivables are in and payables are settled, close your business bank accounts and credit lines. An open business account after closure just accrues fees and muddies the line between business and personal money.
If you carry liability insurance on a claims-made basis, don’t cancel the policy on your closing day. Claims-made coverage only responds to claims reported while the policy is active, so a customer who sues you six months later for work you finished last year would be uncovered. Ask your insurer about tail coverage (an extended reporting period), which keeps the reporting window open after the policy ends. Tail coverage can run from 30 days to several years depending on the policy.
Pull out your commercial lease and any equipment financing or service contracts. A commercial lease usually leaves you liable for rent through the end of the term unless it includes an early termination clause with a buyout. Notice periods for vacating commercial space commonly run 60 to 90 days, sometimes longer. The earlier you talk to your landlord, the less you’re likely to owe.
Cancel Your Florida Fictitious Name
If you did business under any name other than your own legal name, you registered a fictitious name (a DBA) with the Florida Division of Corporations. Florida law requires you to file a cancellation within 30 days after you stop using the name.1Online Sunshine. Florida Statutes 865.09 – Fictitious Name Registration
You can’t cancel online. Download the Fictitious Name Registration application from the Division of Corporations website and complete only Section 4, which handles cancellation.2Florida Department of State.

Close Your Florida Tax Accounts
Sales Tax
If you collected sales tax, cancel your sales tax account through the Florida Department of Revenue’s online account management portal. Select “Cancel” as the status change and enter your closing date.4Florida Department of Revenue. Account Management and Registration You then have 15 days from your closing date to file a final sales tax return and pay what’s owed. The final return covers the period from your most recent filing through the day you stopped doing business.5Florida Department of Revenue. Instructions for DR-15EZ Sales and Use Tax Return
Reemployment Tax
If you had employees, you also have a reemployment tax account (Florida’s name for state unemployment tax) with the Department of Revenue. Close it by mailing Form RTS-5, Application to Terminate Reemployment Tax Account.6Florida Department of Revenue. Form RTS-5 – Application to Terminate Reemployment Tax Account The Department must receive the form by April 30 of the year for which you’re requesting termination. File your final reemployment tax return and clear any balance before that date.
Local Business Tax Receipts and Professional Licenses
Many Florida cities and counties require a local business tax receipt (sometimes still called an occupational license). Contact the tax collector’s office or business licensing department in each jurisdiction where you hold one. Most accept cancellations by phone, mail, or online. If you hold a state-regulated professional license, contact the licensing board directly to request cancellation or inactive status.
File Your Final Federal Returns
Your Last Schedule C
Your business income flows through to your personal return. For the year you close, file Schedule C with your Form 1040, reporting all income and deductible expenses through your final day of operations.7Internal Revenue Service. Closing a Business If your net earnings are $400 or more, you also owe self-employment tax, calculated on Schedule SE.8Internal Revenue Service. Instructions for Schedule SE (Form 1040)
Business Assets You Sell or Stop Using
Sold equipment, vehicles, or other business property as part of winding down? Report those transactions on Form 4797, Sales of Business Property, filed alongside Form 1040.9Internal Revenue Service. About Form 4797, Sales of Business Property Watch for depreciation recapture: when you sell a depreciated asset for more than its adjusted basis, the IRS treats the gain up to the amount of prior depreciation as ordinary income, which can push the tax bill higher than you expected. You may also need Form 4797 if you simply stop using an asset for business and its business-use drops to 50 percent or below for property you expensed under Section 179.7Internal Revenue Service. Closing a Business
1099-NEC for Independent Contractors
If you paid any independent contractor $2,000 or more during the calendar year you close, issue them a Form 1099-NEC and file a copy with the IRS. The $2,000 threshold applies to payments made after December 31, 2025, replacing the previous $600 threshold.10Internal Revenue Service. 2026 Publication 1099
Final Employment Tax Returns
If you had employees, each of the following must be filed and marked as a final return:
- Form 941, for the quarter you pay the final wages. Check the box on line 17 showing the business has closed, enter the date of the final paycheck, and attach a statement naming who will keep the payroll records and where.11Internal Revenue Service. Form 941 – Employer’s Quarterly Federal Tax Return
- Form 940, for the calendar year the final wages are paid. Check box “d” in the Type of Return section to mark it final.12Internal Revenue Service. Form 940 – Employer’s Annual Federal Unemployment (FUTA) Tax Return
- Form W-2 for each employee covering their final year of wages, with a deadline matching the due date of your final Form 941.13Internal Revenue Service. General Instructions for Forms W-2 and W-3 (2026)
Make all final federal tax deposits before you file these returns. Unpaid withholding and payroll taxes can trigger the Trust Fund Recovery Penalty, which the IRS can assess against you personally for the full unpaid amount.
Deactivate Your EIN
The IRS won’t delete an EIN, but it will close the associated business account so no further filing obligations attach to it. Send a letter with your EIN, legal name, address, the EIN assignment notice (if you still have it), and your reason for closing. The IRS will only process the request after all required returns are filed and all taxes paid.14Internal Revenue Service. If You No Longer Need Your EIN
Mail the letter to one of the following:
- Internal Revenue Service, MS 6055, Kansas City, MO 64108
- Internal Revenue Service, MS 6273, Ogden, UT 84201
Terminate Any Retirement Plan
If you set up a SEP-IRA, SIMPLE IRA, solo 401(k), or similar plan, formally terminate it. The IRS requires you to notify all participants and beneficiaries and provide a rollover notice so funds can move to another qualifying account without triggering a taxable distribution.15Internal Revenue Service. Terminating a Retirement Plan Distribute plan assets as soon as administratively practical, and coordinate with your plan custodian on any required filings.
Keep Your Records
Don’t shred anything on your way out. The IRS recommends keeping general tax records at least three years from the date you file your final return. Employment tax records should be kept at least four years after the tax becomes due or is paid, whichever is later.16Internal Revenue Service. How Long Should I Keep Records If income was underreported by more than 25 percent, the IRS has six years to audit, so leaning toward longer retention is sensible. Hold property records, contracts, and anything tied to assets you sold or transferred indefinitely, or at least until the relevant statute of limitations has clearly run.
