Quick Answer
Freelancers typically need to register in states where they have physical presence, employees, or exceed economic nexus thresholds ($100,000+ sales in most states). You'll owe income tax in your home state plus any state where you earn income above their threshold, though most states offer credits to prevent double taxation.

When do you need to register in multiple states?
Freelancers need to register for business licenses and pay taxes in states where they have "nexus" - a sufficient connection to the state. According to the Supreme Court's Wayfair decision and subsequent state laws, nexus is created by:
1. Physical presence: Office, home office, employees, or regularly working in the state
2. Economic nexus: Typically $100,000+ in sales or 200+ transactions annually
3. Affiliate nexus: Related businesses or affiliates in the state
Economic nexus thresholds by state
Important: These thresholds apply to sales/use tax registration. Income tax registration often has lower thresholds or different rules.
Example: Freelance web developer scenario
Meet Sarah, a web developer living in Colorado with clients nationwide:
Her situation:
Registration requirements:
1. Colorado: Must register (home state)
2. California: No registration needed (under $500,000 threshold)
3. New York: No registration needed (under $500,000 threshold)
4. Texas: No state income tax, no registration needed

The four types of multi-state tax scenarios
Scenario 1: Home state only (most common)
You live in one state, work from home, clients pay you directly. You only register and pay taxes in your home state.
Scenario 2: Physical presence in multiple states
You travel to client sites, maintain offices, or work on-location regularly. Register where you have physical presence.
Scenario 3: High revenue across multiple states
You exceed economic nexus thresholds. Register in states where you meet the thresholds.
Scenario 4: Through platforms or marketplaces
Platforms like Upwork, Fiverr may handle some compliance, but you're still responsible for income tax filings.
