The legal steps every online seller must take before and after launch Which website legal pages are legally required - and what goes in them How to deploy cookie consent that actually complies with GDPR US sales tax compliance after the Wayfair ruling changed everything IP and FTC rules that catch new sellers off-guard Why Legal Preparation Matters for Online Sellers Legal issues are one of the most common reasons promising e-commerce businesses fail in their first year. Many operators focus entirely on products and marketing, only to face unexpected liability claims, tax penalties, or platform account suspensions due to non-compliance. The good news: most legal requirements for online sellers are predictable and manageable. This checklist covers the core legal steps every online seller should take before and shortly after launch. In short, legal compliance isn't a one-time event - it's an ongoing part of running a legitimate business. Handle the foundations now and reviewing them annually becomes straightforward. Business Structure and Registration Decide whether to operate as a sole proprietor or form a business entity (LLC or corporation). For most e-commerce sellers, an LLC is the right choice - it gives liability protection without the complexity of a corporation. Fair warning: register for a business license with your local municipality if required (requirements vary by city and state). Get an EIN (Employer Identification Number) from the IRS at irs.gov/ein - it's free and takes five minutes online. You'll need it to open a business bank account and for tax filing. Website Legal Pages Your website must have these four pages before you accept your first order: Privacy Policy - legally required under CCPA, GDPR, and most international privacy laws; discloses how you collect, use, and store customer data Terms of Service - establishes the rules governing use of your site and your relationship with customers Refund and Return Policy - required by most payment processors; prevents costly chargebacks Shipping Policy - sets clear delivery expectations that reduce support contacts and disputes All of these pages should be written in clear, plain language and prominently linked in your site footer. A Refund Policy that's difficult to find or written in confusing legalese doesn't protect you - it encourages chargebacks. Make your return policy easy to find, easy to read, and genuinely fair. Payment processors and platforms look at your chargeback rate. Cookie Consent and GDPR If you use Google Analytics, Facebook Pixel, or advertising cookies - and you serve any customers in the EU, UK, or California - you must implement a cookie consent mechanism that gives users a genuine choice to accept or decline non-essential cookies. A banner with only an "Accept" button doesn't comply with GDPR. Use a certified Consent Management Platform (CMP) like Google Funding Choices, CookieYes, or Cookiebot to implement compliant consent collection. Failure to comply can result in fines up to €20 million or 4% of global annual revenue under GDPR. Honest answer: pre-ticked consent boxes and "Accept All / Settings" banners (with no visible Reject option) are non-compliant under GDPR. Regulators have fined businesses of all sizes for this. Accept and Reject must be equally prominent. Sales Tax Compliance Since the 2018 South Dakota v. Wayfair Supreme Court decision, US online sellers may owe sales tax in states where they meet economic nexus thresholds - typically $100,000 in sales or 200 transactions in a state per year. Currently over 45 states impose sales tax. Use software like TaxJar (starting at $19/month) or Avalara to automate rate calculation at checkout and generate reports for filing. Both integrate directly with Shopify and WooCommerce. Register for a sales tax permit in each state where you have nexus - selling without a permit can result in back taxes, penalties, and interest.

Frequently Asked Questions

Do I need a lawyer to launch an online store?

Not necessarily for a basic launch. Many online tools and templates can help you create legal pages and form an LLC. However, consult a lawyer if you are dealing with complex IP issues, wholesale contracts, or significant investment.

What is GDPR and does it apply to me?

GDPR (General Data Protection Regulation) is EU data privacy law. If any of your customers are in the EU/EEA, GDPR applies to you regardless of where your business is located. You must have a compliant Privacy Policy, cookie consent mechanism, and data handling practices.

Do I need a business license to sell online?

Requirements vary by location and business type. Most local jurisdictions require a basic business license. Some product categories (food, supplements, firearms) require additional permits. Check with your state and local government for specific requirements.
