Legal Compliance Checklist: Essential Requirements Based on Your Business Model

Legal compliance isn’t one-size-fits-all. What an e-commerce store needs differs dramatically from a SaaS company or consulting practice. Yet most compliance guides dump a mountain of generic requirements on you, leaving you to figure out what actually applies to your business.
After helping dozens of entrepreneurs navigate compliance requirements, I’ve noticed a pattern: business owners either overspend on unnecessary compliance measures or dangerously underinvest in critical ones. Both mistakes can be costly.
This guide breaks down exactly what you need based on your specific business model—no more, no less.
Universal Compliance Requirements (All Business Models)
Before diving into model-specific requirements, let’s cover the baseline every business needs:
Business Formation & Registration
- Business structure registration: File appropriate formation documents (LLC, Corporation, etc.) with your state
- Business name registration: File DBA (“doing business as”) if operating under a name different from your legal entity
- EIN (Employer Identification Number): Obtain from the IRS for tax purposes
- Local business licenses: Check city/county requirements
- State tax registration: Register for sales tax collection if applicable
Financial Compliance

Now let’s get specific based on your business model.

The most successful businesses I’ve worked with don’t just check compliance boxes—they integrate compliance into their operational DNA, making it a seamless part of how they do business.
