How state apportionment works for freelance income
State apportionment determines how your freelance income gets divided among states for tax purposes. Most states use either a traditional three-factor formula or a modern single-factor approach. The three-factor formula considers property (33%), payroll (33%), and sales (33%). However, 32 states now use single-factor sales apportionment, focusing only on where your customers are located.
Example: $150,000 freelance consultancy across three states
Let's say you're a freelance consultant earning $150,000 annually with clients in California, Texas, and New York. You live in Texas (no state income tax) but work from a home office.
Traditional Three-Factor Formula (if applicable):
Single-Factor Sales Formula (more common):
Key factors that determine apportionment
States with unique freelancer rules
What you should do
1. Track income by client location and your work location
2. Monitor state nexus thresholds ($1,000-$10,000 typically)
3. File returns in states where you exceed thresholds
4. Consider forming an LLC in a tax-friendly state for business income
5. Use our quarterly estimator to calculate multi-state tax obligations
Key takeaway: Single-factor sales apportionment means you'll typically pay state taxes based on where your clients are located, not where you work. Track client locations carefully and prepare to file in multiple states once you exceed $1,000-$10,000 thresholds.
