Starting an eCommerce business is an exciting journey, but before you start selling online, you must ensure your business is legally compliant. From registering your business to collecting sales tax and following data privacy laws, there are several legal requirements every online store owner must know.
Ignoring these regulations can lead to fines, legal trouble, or even the shutdown of your business. Here we walk through the key legal aspects of running an eCommerce store, including business licenses, taxes, and essential regulations.

Business Structure and Registration
Before launching your eCommerce store, you need to decide on a legal business structure. The structure you choose affects taxes, liability, and how you operate your business.
Common eCommerce Business Structures:
- Sole Proprietorship: The simplest structure; you and your business are legally the same entity. No formal registration required, but you are personally liable for debts.
- Limited Liability Company (LLC): A popular choice for eCommerce businesses as it offers liability protection while keeping taxes simple.
- Corporation (C-Corp or S-Corp): Best for larger businesses looking for investors or complex ownership structures.
How to Register Your Business:
- Choose a business name and check its availability.
- Register with your state’s business regulatory office.
- Obtain an Employer Identification Number (EIN) from the IRS (required for LLCs and corporations).
Pro Tip: If you plan to operate under a different name than your registered business name, file for a “Doing Business As” (DBA) registration.
Business Licenses and Permits
Even though eCommerce businesses operate online, many states and local governments require business licenses.
Common eCommerce Licenses and Permits:
- General Business License: Required in most states to legally operate a business.
- Seller’s Permit (Sales Tax License): Required if you sell physical products in states that collect sales tax.
- Home Occupation Permit: Required in some states if you run your business from home.
- Import/Export License: If you import or export goods internationally, you may need additional permits.
Where to Apply: Check your state’s Secretary of State website or local business regulatory office.
eCommerce Taxes: What You Need to Know
Taxes can be complicated for eCommerce businesses, especially when selling in multiple states or countries. Here are the key taxes you need to understand.
Sales Tax
In the U.S., sales tax laws vary by state. Some states require you to collect and remit sales tax if you have a “nexus” in that state.
What Creates Sales Tax Nexus?
- Having a physical location in the state (office, warehouse).
- Employing workers or contractors in the state.
- Reaching a sales threshold (e.g., $100,000 in sales in a state).
How to Comply:
- Register for a sales tax permit in each required state.
- Use sales tax automation tools like TaxJar or Avalara.
- Remit collected sales tax to the state as required (monthly, quarterly, or annually).
Income Tax
All eCommerce businesses must pay federal income tax, and many also owe state income tax depending on where they are based.
How to Stay Compliant:
- Keep detailed records of revenue and expenses.
- Set aside money for tax payments to avoid surprises.
- Hire an accountant or use tax software for filing.
International Tax Considerations
If you sell internationally, you may need to collect VAT (Value-Added Tax) for sales in the EU, UK, and other regions.
How to Handle International Taxes:
- Register for VAT if required in the countries you sell to.
- Use tax calculation tools for compliance.
Consumer Protection and Privacy Laws
eCommerce businesses must follow laws that protect consumers and their data. Here are key regulations to be aware of.
Data Privacy Laws
If you collect customer information (names, emails, addresses), you must comply with data privacy laws.
- General Data Protection Regulation (GDPR): Required if you sell to customers in the European Union.
- California Consumer Privacy Act (CCPA): Applies if you sell to California residents and meet certain criteria.
How to Stay Compliant:
- Post a clear privacy policy on your website.
- Allow customers to opt-out of data collection.
- Use secure payment processing to protect customer data.
Consumer Protection Laws
To protect customers from fraud and misleading advertising, eCommerce businesses must follow fair business practices.
- Truth in Advertising: No false or misleading product claims.
- Refund and Return Policies: Clearly state your return and refund policy on your website.
- CAN-SPAM Act: If you send marketing emails, you must allow users to unsubscribe easily.
Website Policies You Need
To protect your business and customers, your website should include essential legal pages.
- Privacy Policy: Explains how you collect, use, and protect customer data.
- Terms and Conditions: Covers rules for using your website and making purchases.
- Refund & Return Policy: Sets clear guidelines for product returns and refunds.
- Shipping Policy: Details estimated shipping times and costs.
The legal side of eCommerce may seem overwhelming, but taking the time to set up your business correctly will save you from potential legal headaches down the road. Ensuring compliance with licenses, taxes, and regulations will protect your business and build trust with your customers.
