How to Set Up a Side Business in Florida: LLC, Bank Account and Bookkeeping Basics

Plenty of Floridians start a business on the side: weekend photography, bookkeeping for a few clients, a small online shop, handyman work, tutoring. A side business can stay simple, but a few setup decisions made early save a lot of cleanup later. This guide covers the order most owners follow: choose a structure, register, get a tax ID, separate your money, and set up basic books.

Step 1: Check your day job first

Before you register anything, read your employment agreement or employee handbook. Some employers restrict outside work, work for competitors or clients, or the use of company equipment and time. If anything is unclear, ask HR or an employment attorney. It's much easier to sort this out before you have customers.

Step 2: Choose a structure

Most side businesses start as one of two things:

• Sole proprietorship. If you simply start selling under your own name, you're generally treated as a sole proprietor. There's no state filing to create it, but there's also no legal separation between you and the business.
• Limited liability company (LLC). An LLC is a separate legal entity registered with the state. It can help separate business obligations from personal ones when it's set up and run properly, and many owners like the clearer line between business and personal finances.

By default, a single-member LLC is usually taxed like a sole proprietorship for federal income tax (the IRS calls it a "disregarded entity"), so forming one doesn't automatically change how you file. Our sole proprietor vs. LLC guide compares the two side by side. A tax professional can tell you which fits your situation.

Step 3: Register with the state (if you form an LLC)

Florida LLCs are formed by filing Articles of Organization with the Florida Division of Corporations, which runs the state's business registry at sunbiz.org. In general you'll:

1. Search the name on Sunbiz to make sure it's available and distinguishable from existing names. The name must include "Limited Liability Company," "LLC" or a similar designator.
2. Name a registered agent with a Florida street address who can accept legal mail during business hours. You can serve as your own if you meet the requirements, though many side-business owners use a service for privacy.
3. File the Articles of Organization online and pay the state fee. At the time of writing, the required state fees total $125; check Sunbiz for current amounts.
4. Calendar the annual report. Florida LLCs file an annual report each year between January 1 and May 1 to stay active, and a late fee applies after May 1.

Our step-by-step Florida LLC guide covers each of these in more detail.

Using a different name? If you'll operate under a name other than your own legal name (as a sole proprietor) or your LLC's exact registered name, Florida generally requires a fictitious name registration, also filed on Sunbiz.

Step 4: Get an EIN

An Employer Identification Number (EIN) is a federal tax ID for your business. You apply for free directly on IRS.gov; there's no reason to pay a third-party site. LLCs and businesses with employees typically need one, and most banks ask for it to open a business account. Even sole proprietors often get one so they don't have to hand out their Social Security number to clients.

Step 5: Check licenses and sales tax

• Local business tax. Many Florida counties and cities require a local business tax receipt. Check with your county tax collector and your city.
• Professional or trade licenses. Some work (for example, many construction trades, cosmetology and real estate) requires a state license. Check with the Florida Department of Business and Professional Regulation if your work might be covered.
• Sales tax. If you sell taxable goods or services in Florida, you generally need to register with the Florida Department of Revenue before you start collecting.
• Home-based rules. If you'll work from home, check any zoning, HOA or lease rules that apply.

Our startup checklist lists these steps in order.

Step 6: Open a separate business bank account

This is the single most useful habit for a side business. A dedicated account:

• makes bookkeeping and tax time far simpler,
• helps keep an LLC's finances clearly separate from yours, and
• shows you at a glance whether the business is actually bringing in more than it spends.

Banks usually ask for your EIN, your LLC's filed Articles (or your fictitious name registration), and ID. Requirements vary, so call ahead or check the bank's site. The SBA's guide explains what to expect. Use a separate card for business purchases too.

Step 7: Set up simple bookkeeping

You don't need a complicated system for a side business, but you do need a consistent one.

• Pick a tool. A spreadsheet works at first; bookkeeping software helps once you have regular transactions.
• Choose categories that match how you'll report income and expenses on your tax return. Your tax professional can help you set these up once.
• Save receipts as you go, ideally as photos or files in one folder.
• Do a monthly catch-up: categorize transactions, reconcile against your bank statement and send any overdue invoices.
• Plan for taxes. Side-business profit is usually subject to income tax and, for most self-employed people, self-employment tax. Many owners need to make quarterly estimated payments. The IRS self-employed tax center explains the basics, and a tax professional can help you estimate what to set aside.

Step 8: Protect your time

The hardest part of a side business is usually time, not paperwork. A few habits help:

• Set fixed business hours each week and share them with clients.
• Keep one inbox and one task list for the business.
• Write down the steps for your most common job so it gets faster each time.
• Review how things are going once a month using our operations checklist.
