To start a sole proprietorship in Florida, you simply begin doing business — there is no incorporation filing, and you become a sole proprietor the moment you start. What you do need to handle around that: register a fictitious name if you’ll use one, get a federal tax ID, sign up for sales tax if you sell taxable goods or services, pick up a local business tax receipt from your county or city, and confirm no professional license or zoning rule applies to your work. Because there is no legal separation between you and the business, your personal assets are on the line for its debts and lawsuits.
Register a Fictitious Name if You Use One
If you operate under any name other than your full legal name, Florida treats that as a “fictitious name” and requires registration with the state. The definition is broad and covers creative brand names as well as shortened versions of your own name.1Florida Senate. Florida Code 865 – Fictitious Name Registration Operating under your exact legal name with nothing added? You can skip this entirely.
Before filing, search the Florida Division of Corporations database at Sunbiz.org to see whether your name is already in use. The search covers corporations, LLCs, limited partnerships, and trademarks.2Florida Department of State. Search Records
Filing the Application
Register through the Sunbiz e-filing portal using the Application for Registration of Fictitious Name. Florida requires you to certify on the application that the name has been advertised at least once in a newspaper located in the county where your principal place of business operates.3Florida Division of Corporations. Application for Registration of Fictitious Name You don’t submit proof of the ad; you just certify it when signing.4Division of Corporations – Florida Department of State. Florida Fictitious Name Registration Newspaper notice costs typically run from about $25 to $85 depending on the county.
The state filing fee is $50, with an optional $30 for a certified copy of the registration certificate.5Florida Department of State. Fees – Division of Corporations Registration lasts five years and expires on December 31 of the final year, so renew before that date to keep it active.4Division of Corporations – Florida Department of State. Florida Fictitious Name Registration An active registration is required to sign contracts or enforce legal rights under the business name.
The application asks for your full legal name, a mailing address, and the Florida county of your principal place of business. You may enter a federal Employer Identification Number if you have one, but the state’s instructions specifically warn against putting a Social Security number on the form.6Division of Corporations – Florida Department of State. Fictitious Name Registration Instructions
Unlike LLCs and corporations, sole proprietors are not required to file a Florida annual report. The five-year fictitious name renewal is the only recurring state filing you’ll have.7Division of Corporations – Florida Department of State. File Annual Report
Get an Employer Identification Number
An EIN is a nine-digit number the IRS issues to businesses for tax purposes. If you have no employees and don’t plan to open a separate business bank account, you can technically use your Social Security number. Most sole proprietors get an EIN anyway, because banks usually require one to open a commercial account and using an EIN on invoices and tax documents keeps your SSN private.
Apply online for free at IRS.gov using Form SS-4. The number is issued immediately once approved. The online session expires after 15 minutes of inactivity and can’t be saved, so have your information ready before you start.8Internal Revenue Service. Get an Employer Identification Number
Register for Florida Sales Tax if You Sell Taxable Goods or Services
If your business sells or leases taxable goods or services, you must register with the Florida Department of Revenue. The state sales tax rate is 6%, and most counties add a discretionary surtax on top.9Florida Department of Revenue. Tax and Interest Rates Register by filing the Florida Business Tax Application (Form DR-1) online or by mail.10Florida Department of Revenue. Account Management and Registration
Once processed, you receive a Certificate of Registration along with an Annual Resale Certificate. Allow at least three business days for the online application to process before checking its status.10Florida Department of Revenue. Account Management and Registration The Department mails a welcome package with your certificate and a new-dealer guide.
Get a Local Business Tax Receipt
Most Florida counties and municipalities require a Local Business Tax Receipt — formerly called an occupational license — before you can operate. You obtain it from your county or city tax collector’s office, and it confirms your business complies with local zoning and safety rules. Fees vary by jurisdiction and business type but commonly fall in the $25 to $100 range for small sole proprietorships. If your business is inside city limits, you may need both a county receipt and a separate city receipt.11Miami-Dade Tax Collector. Local Business Tax Receipt
Once issued, you must display the receipt prominently at your place of business where the public can see it.11Miami-Dade Tax Collector. Local Business Tax Receipt Contact your local tax collector for its specific application forms, fees, and required documents.
Check Professional Licensing and Zoning
Some lines of work require a state-issued professional or industry license before you can legally operate. The Florida Department of Business and Professional Regulation covers many regulated professions; the Department of Agriculture and Consumer Services covers a separate set of industries.12Florida Department of State. Get a Business License – Division of Library and Information Services Check both to see whether your work falls under a state licensing scheme. Operating without a required license can bring fines or a shutdown order.
Home-Based Business Zoning
Running the business from home? Check your local zoning ordinances first. Most Florida municipalities allow small, quiet home-based businesses in residential zones, but rules vary widely. Common restrictions include limits on customer foot traffic, signage, noise, and how many employees can work at the residence. Homeowners’ association and condominium rules can be stricter than city ordinances and sometimes ban commercial activity outright. Your city or county planning department can tell you what’s allowed.
Set Up Your Federal Taxes
Florida has no state personal income tax, but federal income tax and self-employment tax still apply to your business profits. You report income and expenses on Schedule C, filed with your personal Form 1040. Your Schedule C net profit flows onto your personal return and is taxed at your regular income tax rate.
Self-Employment Tax
On top of income tax, you pay self-employment tax of 15.3% on your net earnings: 12.4% for Social Security and 2.9% for Medicare.13Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) The Social Security portion applies only to the first $184,500 of net self-employment income in 2026; the Medicare portion has no cap.14Social Security Administration. Contribution and Benefit Base You can deduct the employer-equivalent half of your self-employment tax (7.65%) when calculating adjusted gross income.
Quarterly Estimated Tax Payments
Since no employer is withholding for you, the IRS expects quarterly estimated payments covering both income tax and self-employment tax. For 2026, the deadlines are:
- 1st quarter: April 15, 2026
- 2nd quarter: June 15, 2026
- 3rd quarter: September 15, 2026
- 4th quarter: January 15, 2027
You can skip the January 15 payment if you file your full 2026 return and pay the balance by February 1, 2027.15IRS.gov. Form 1040-ES – Estimated Tax for Individuals Missing a deadline triggers an underpayment penalty even if you pay everything owed at year-end.
Schedule C lets you deduct ordinary and necessary business expenses before calculating tax — common categories include vehicle expenses (the 2026 standard mileage rate is 72.5 cents per mile16Internal Revenue Service. 2026 Standard Mileage Rates), home office use, supplies, professional services, insurance premiums, rent, utilities, and 50% of business meals.17Internal Revenue Service. Instructions for Schedule C (Form 1040) Keep receipts for everything you claim.
File for the Tangible Personal Property Tax Exemption
If your business owns equipment, furniture, fixtures, or other physical assets, you may owe tangible personal property tax to your county. Florida offers an exemption of up to $25,000 in assessed value, but you must file a return with your county property appraiser by April 1 each year to claim it.18Florida Department of Revenue. Taxpayers – Tangible Personal Property Stay under the threshold and file on time and you owe nothing. Skip the filing and you lose the exemption even if your assets would have qualified.
Protect Yourself With Insurance
A sole proprietorship offers no liability shield. A lawsuit or major claim puts your personal assets, including your home, savings, and vehicles, directly at risk. Insurance is the primary way to manage that exposure.
- General liability insurance covers bodily injury to non-employees, property damage, and related legal defense costs. It’s the most common starting policy for small businesses.19U.S. Small Business Administration. Get Business Insurance
- Professional liability insurance, also called errors and omissions coverage, protects service-based businesses when a client claims financial harm from your work.
- Commercial property insurance covers damage to your equipment and inventory from fire, theft, or natural disasters.
No Florida law requires sole proprietors without employees to carry general liability insurance, but many clients and landlords require proof of coverage before signing a contract.
If You Hire Employees
Hiring triggers a separate set of obligations. You’ll need an EIN if you don’t already have one. Every new hire completes Form I-9, which you keep for three years after the hire date or one year after employment ends, whichever is later.20U.S. Citizenship and Immigration Services. 10.0 Retaining Form I-9 You withhold federal income tax and the employee’s share of Social Security and Medicare, and pay the employer’s matching share. Federal Unemployment Tax (FUTA) applies at 6.0% on the first $7,000 of each employee’s wages, with a credit of up to 5.4% for paying state unemployment on time, bringing the effective FUTA rate to 0.6%.21Internal Revenue Service. Publication 926 (2026), Household Employer’s Tax Guide
Florida’s version of state unemployment insurance is called reemployment tax. New employers pay an initial rate of 2.7% on employee wages until they’ve reported for at least 10 quarters, after which the rate is adjusted based on the employer’s claims history.9Florida Department of Revenue. Tax and Interest Rates You register through the same Department of Revenue portal where you filed the DR-1.
Workers’ compensation rules depend on your industry. Florida sole proprietors in non-construction industries with three or fewer employees are not required to carry workers’ compensation, and the owner is not counted in that total. Construction-related work is subject to different and stricter coverage requirements regardless of employee count.22Florida CFO. Educational Information Determining Workers’ Compensation
