What are the legal requirements for starting a business?​

The dream vs. the fine print: Why legal requirements matter

Lisa had it all figured out. She spent years perfecting her craft—handmade candles with scents that transported people to their favorite places. Her online following was growing, friends were asking when they could buy, and she was finally ready to turn her passion into a business.

So, she did what many excited entrepreneurs do. She built a website, designed a logo, and even ordered fancy packaging. But there was one thing she didn’t do—handle the legal side.

The first sign of trouble came when she tried to open a business bank account, and the bank asked for an EIN (Employer Identification Number). Then, she received a notice that another company had trademarked the name she was using. A few weeks later, her city’s health department sent a warning—she needed a permit to sell products with fragrances.

What started as an exciting venture turned into a stressful legal puzzle. She wasn’t alone. Plenty of entrepreneurs charge full speed ahead, only to find out the rules they didn’t know existed can stall, or even shut down, their business.

Here’s the thing: starting a business is more than just having a great idea and a killer marketing plan. It’s also about making it official—the right way. And while legal requirements might not be the most exciting part of entrepreneurship, ignoring them can lead to fines, lawsuits, or worse, having to shut everything down.

The good news? You don’t need a law degree to navigate the legal side of business. You just need to know what steps to take, and that’s exactly what we’re going to break down. Let’s make sure your business is built on a solid foundation—without any unwelcome surprises.

Choosing the right business structure (Because it shapes everything)

When James and Alex decided to start a bakery together, they figured the hardest part would be perfecting their recipes. They didn’t think too much about the legal side of things, so they kept it simple—James ran the business as a sole proprietor, while Alex registered an LLC for his share of operations.

At first, things ran smoothly. But when a customer had a severe allergic reaction and sued, James was in for a rude awakening. As a sole proprietor, he was personally responsible for all business debts and liabilities. His personal savings and even his house were on the line. Meanwhile, Alex’s liability was limited—his personal assets were protected because of his LLC.

This is the kind of situation most entrepreneurs don’t think about when they’re starting out. But the business structure you choose determines everything—your taxes, liability, paperwork, and even how you raise money in the future.

Here’s a quick breakdown of the main options:

  • Sole Proprietorship – The easiest and most common choice for freelancers and small businesses. You and your business are legally the same, which means you report income on your personal tax return. The downside? If something goes wrong, your personal assets are on the line.
  • Limited Liability Company (LLC) – A step up in protection. Your personal assets are separated from your business, reducing your liability. It also offers flexibility in how you’re taxed.
  • Corporation (C-Corp or S-Corp) – Best for businesses looking to scale, raise investment, or have multiple owners. More paperwork, but more protections. C-Corps are taxed separately from owners, while S-Corps pass income through to shareholders to avoid double taxation.

Many small business owners start with a sole proprietorship because it’s simple, but that simplicity comes with risks. If your business involves even a small chance of liability—whether from customers, contracts, or regulations—an LLC might be a better choice.

The bottom line? Your business structure isn’t just a formality—it’s a decision that affects everything from taxes to lawsuits. Choose wisely, because the right setup today can save you a world of trouble tomorrow.

Business registration: Making it official

Samantha spent weeks brainstorming the perfect name for her boutique jewelry brand. She checked Instagram, saw the handle was available, and even bought the domain. Everything was falling into place—until she went to register her business and found out the name was already taken.

That’s when she learned the hard way: just because a name is available online doesn’t mean it’s legally yours.

Registering your business makes it official, and skipping this step can lead to serious headaches. Here’s what it involves:

  • Checking for name availability – Every state has a database where you can search for registered business names. If the name is taken, you’ll need to come up with something else.
  • Trademarking (if necessary) – Even if a name is available in your state, another company could own the trademark, which means they can force you to change it later. A quick search on the U.S. Patent and Trademark Office (USPTO) website can save you from future legal trouble.
  • Filing the right paperwork – Sole proprietors may only need to register a DBA (Doing Business As) if they operate under a different name. LLCs and corporations must file formation documents with their state.

Samantha ended up having to rebrand, redesign her website, and order new packaging—all because she didn’t check for trademarks first. A little paperwork upfront can save a lot of stress down the road.

Getting the right licenses and permits

Marcus was thrilled when his home-based catering business started taking off. Word spread fast, and soon he had a steady stream of orders. Everything was going smoothly—until a health inspector showed up at his door.

Turns out, he needed a food service permit to legally sell homemade meals. Since he didn’t have one, he was forced to shut down temporarily and pay a fine before he could get back to business.

A lot of entrepreneurs assume they don’t need a license, especially if they’re working from home or selling online. But most businesses—whether big or small—need some kind of permit to operate legally.

Here’s what to check for:

  • Federal licenses – If your business involves selling alcohol, firearms, agriculture, or anything regulated by the federal government, you’ll need special approval.
  • State and local permits – These vary depending on location and industry. Common ones include health permits (for food businesses), seller’s permits (for collecting sales tax), and professional licenses (for fields like real estate or cosmetology).
  • Home-based business restrictions – Some cities require special permits to run a business from home, especially if it involves foot traffic or deliveries.

Marcus could have avoided his legal trouble with a simple online search or a call to his local business office. A missing permit might not seem like a big deal—until it forces you to pause operations or pay penalties.

Taxes, EINs, and why the IRS needs to know you exist

Vanessa was making good money as a freelance designer. She had steady clients, regular payments, and everything seemed great—until tax season rolled around. That’s when she realized she owed way more than she expected. She had never set aside money for self-employment taxes, and to make matters worse, she didn’t have an EIN, which made filing her taxes even more complicated.

Business taxes aren’t something you can figure out later. The IRS expects you to handle them from day one, and missing the details can cost you.

Here’s what every business owner needs to know:

  • Getting an EIN (Employer Identification Number) – Even if you don’t have employees, an EIN is essential for filing taxes, opening a business bank account, and keeping your personal finances separate. You can get one for free through the IRS website.
  • Understanding self-employment taxes – Unlike traditional employees, business owners don’t have taxes automatically withheld. That means you’re responsible for paying income tax and self-employment tax (which covers Social Security and Medicare).
  • Quarterly tax payments – If you’re making money, the IRS expects you to pay taxes four times a year, not just in April. Failing to do this can lead to penalties.
  • State and local taxes – Depending on where you live, you may also owe state business taxes, sales tax, or other local fees.

Vanessa learned her lesson after a stressful tax season. She hired an accountant, started making quarterly payments, and got her EIN to keep everything organized. A little planning upfront saves a lot of financial headaches later.

Business banking and financial compliance

Daniel ran a successful online shop selling handmade leather wallets. At first, he kept things simple—his customers paid through his personal PayPal account, and he used his personal checking account for business expenses. It didn’t seem like a big deal.

That changed when tax season rolled around. His accountant asked for his business expenses, but everything was mixed in with his personal spending. Sorting through months of transactions was a nightmare. Worse, when a customer disputed a charge, PayPal froze his entire account—including his personal funds—because they saw him as an unregistered business.

Mixing personal and business finances is one of the most common mistakes new entrepreneurs make. It might seem harmless at first, but it can lead to tax issues, legal risks, and even banking complications.

Here’s what every business owner should do:

  • Open a business bank account – This keeps your business finances separate and makes tax filing much easier. Most banks require an EIN and business registration documents.
  • Get a business credit card – Helps build credit and keeps business expenses organized. Plus, some cards offer rewards for business purchases.
  • Use accounting software or a professional – Whether it’s QuickBooks, Wave, or hiring an accountant, tracking expenses properly from the start saves a ton of hassle later.
  • Understand record-keeping rules – The IRS requires businesses to keep financial records for several years. Organized bookkeeping helps in case of an audit.

Daniel eventually opened a business account and started tracking his finances properly. But if he had done it from the beginning, he could have avoided the stress, tax confusion, and the frozen PayPal funds.

Contracts, agreements, and the legal safety net

Mia was a talented web developer who landed her biggest freelance project yet—a full website redesign for a growing startup. She poured weeks of work into the project, delivered everything on time, and waited for her final payment. It never came.

When she reached out, the client ghosted her. No emails, no responses—just silence. And since she had no written contract, she had no legal ground to demand payment.

Too many entrepreneurs learn this lesson the hard way: a handshake deal isn’t enough. Without a written agreement, you have no protection if things go south.

Here’s what every business owner needs to safeguard themselves:

  • Written contracts for every deal – Whether it’s clients, vendors, or business partners, always have a written agreement that outlines payment terms, deadlines, and expectations.
  • Clear terms and conditions – If you sell products or services online, your website should include terms of service, refund policies, and disclaimers.
  • Non-disclosure agreements (NDAs) – If you’re sharing sensitive business information with employees, freelancers, or partners, an NDA can prevent them from misusing it.
  • Business insurance – Even if you do everything right, things can still go wrong. General liability insurance protects against lawsuits, while professional liability insurance covers service-based businesses.

Mia now sends contracts before starting any project. It took one bad experience to realize that legal protection isn’t an afterthought—it’s a necessity.

Employee laws and hiring (Even if it’s just one person)

David’s e-commerce business was booming, and he finally reached the point where he needed help. He hired his friend Sarah as a part-time assistant and paid her under the table. No paperwork, no payroll taxes—just quick cash at the end of each week.

Things were fine until Sarah got injured while picking up supplies. She filed for workers’ compensation, but since David never officially hired her, there was no record of employment. That’s when he learned the hard way: hiring someone isn’t just about paying them—it comes with legal responsibilities.

Even if you’re only bringing on one employee, here’s what you need to do:

  • Register as an employer – You’ll need to file with the IRS and get an EIN if you haven’t already. Most states also require businesses to register for state payroll taxes.
  • Classify workers correctly – The difference between an employee and an independent contractor matters. Misclassifying someone can lead to serious penalties from the IRS.
  • Set up payroll taxes – Employers must withhold Social Security, Medicare, and income taxes from employee wages. Independent contractors, on the other hand, handle their own taxes.
  • Follow labor laws – Minimum wage, overtime pay, and workplace safety regulations all apply, even for small businesses.
  • Get workers’ compensation insurance – Required in most states, this protects your business if an employee gets injured on the job.

David had to pay fines, back taxes, and unexpected legal fees to fix his mistake. A little paperwork upfront could have saved him a major headache.

Privacy policies, online compliance, and protecting customer data

Sophie launched a subscription-based fitness coaching website and quickly built a solid client base. Everything was running smoothly until she received an unexpected email—a legal notice from a customer demanding to know how their personal data was being stored and used. Sophie had never created a privacy policy, let alone thought about data compliance. Now, she was scrambling to figure out what she had overlooked.

If you collect any kind of customer information—email addresses, payment details, even browsing behavior—you’re responsible for protecting it. Privacy laws aren’t just for big corporations. Small businesses can face hefty fines if they don’t comply.

Here’s what every online business owner needs to have in place:

  • Privacy policy – If you collect customer data, you need a clear privacy policy outlining what you collect, how you use it, and whether you share it with third parties.
  • Terms of service – This protects you by setting clear rules for how customers can use your site, including disclaimers and liability limits.
  • Compliance with data privacy laws – Regulations like the GDPR (General Data Protection Regulation) in Europe and the CCPA (California Consumer Privacy Act) in the U.S. require businesses to be transparent about data collection. Even if you’re based elsewhere, these laws may still apply if you serve customers in those regions.
  • Secure payment processing – Using trusted payment providers like Stripe or PayPal ensures that financial data is handled securely.
  • Customer consent for marketing – If you’re sending emails or tracking user behavior with cookies, you need explicit consent (think opt-in checkboxes and cookie banners).

Sophie had to rush to put these policies in place before facing potential legal trouble. If she had done it from the start, she could have saved herself the panic—and the risk of fines.

The road ahead: Legal isn’t a one-time thing

Carlos thought he had everything covered. He registered his business, got the right licenses, set up contracts, and even had a solid tax plan. For the first year, things ran smoothly. Then, he expanded his services to a new state—and realized too late that he needed additional permits. A few months later, a change in tax laws increased his filing requirements.

Many business owners assume legal compliance is a one-and-done task. But the truth is, the rules change, and what worked on day one might not be enough a year later. Staying compliant isn’t just about launching your business—it’s about protecting it as it grows.

Here’s how to stay on top of things:

  • Keep up with legal changes – Tax laws, employment regulations, and business requirements shift. Checking in with a business attorney or accountant annually can save you from surprises.
  • Renew licenses and permits – Some business licenses expire after a year or two. Make sure you know when renewals are due.
  • Update contracts and policies – As your business evolves, so should your agreements. If you add new services, change pricing, or expand operations, update your contracts accordingly.
  • Monitor tax requirements – Expanding to a new state? Hiring employees? These can trigger new tax obligations, so stay ahead of the paperwork.

Carlos learned that legal upkeep isn’t a burden—it’s a safeguard. A little proactive effort keeps a business running smoothly, avoiding costly missteps down the road.
