Quick Answer
You typically file tax returns in your home state (where you live) and may need to file in states where you earned income. Most states have a threshold—often $1,000-$5,000—before requiring a return. You'll generally get credits for taxes paid to other states to avoid double taxation.

Best for freelancers in their first year who are overwhelmed by multi-state tax requirements
Where do you file when earning income in multiple states?
As a freelancer earning income across state lines, you'll typically need to file a tax return in your home state (where you live and are domiciled) plus potentially file non-resident returns in states where you earned income above certain thresholds.
Here's the basic rule: Your home state taxes all your income regardless of where you earned it. Other states may tax income you earned within their borders if it exceeds their filing threshold.
Example: Freelancer living in Texas with clients in California and New York
Let's say you live in Austin, Texas and earned:
Texas: No state income tax, so no return required.
California: You earned $15,000 there. California requires non-residents to file if they earned more than $1,000 in the state. You'll file Form 540NR and owe California tax on the $15,000.
New York: You earned $8,000 there. New York's threshold is typically $1,000+ for non-residents, so you'll file Form IT-203 and owe New York tax on the $8,000.
State filing thresholds for non-residents
*Note: Thresholds change annually. Always check current state requirements.*
How to avoid double taxation
The key protection is the resident state tax credit. If you live in a state with income tax (like California, New York, or Virginia), you'll:
1. File your home state return reporting all $35,000 of income
2. File non-resident returns in states where you exceeded thresholds
3. Claim credits on your home state return for taxes paid to other states
Example calculation:
Key factors that determine your filing requirements
What you should do
1. Track income by client location throughout the year
2. Research filing requirements for each state where you earned income
3. File your home state return first to establish your baseline tax
4. File non-resident returns for states where you exceeded thresholds
5. Claim appropriate credits to avoid double taxation
Start tracking this information now using a system that categorizes income by state. The earlier you organize this, the easier tax season becomes.
Key takeaway: Most freelancers file in their home state plus 1-3 non-resident states, but you'll get credits to avoid paying tax twice on the same income. States typically require filing once you earn $1,000-$5,000 there.

Key Takeaway: File in your home state for all income, plus non-resident returns where you exceeded state thresholds (usually $1,000-$5,000), but you'll get credits to avoid double taxation.
Common state filing thresholds and forms for non-resident freelancers

| Pennsylvania | $33+ | Form PA-40 NR | 3.07% |
| Virginia | $11,950+ | Form 760PY | 2-5.75% |

Best for people with W-2 jobs who also freelance across state lines
Managing multi-state income when you already have a W-2
As someone with both W-2 employment and freelance income across states, your situation is more complex but manageable. Your W-2 job likely already handles one state's taxes through payroll withholding, but your freelance income creates additional filing requirements.
Your W-2 vs. 1099 state obligations
W-2 income: Your employer handles withholding for the state where you work (or where they're headquartered). This appears on your W-2 in boxes 15-20.
1099 income: No withholding happens automatically. You're responsible for taxes in every state where you earned freelance income above their thresholds.
Example: W-2 employee in Illinois with freelance clients elsewhere
You live in Chicago, earn $65,000 W-2 from your Illinois employer, plus:
Illinois return: Report all $78,000 ($65,000 W-2 + $13,000 freelance). Illinois already withheld tax on your W-2 income.
California return: File Form 540NR for the $6,000 freelance income. You'll owe California tax on this amount.
New York return: File Form IT-203 for the $3,000 freelance income.
Illinois will give you credits for taxes paid to California and New York, so you don't pay twice.
Quarterly payment strategy
Since your W-2 job already handles withholding for your main state, focus your quarterly payments on covering:
1. Federal self-employment tax on all freelance income (15.3%)
2. State taxes for non-resident filing states
3. Additional home state tax if your combined income pushes you into higher brackets
Quick calculation: If you earn $10,000 freelance income in states with ~5% tax rates, budget about $500 for additional state taxes beyond what your W-2 withholding covers.
What makes this easier
Your W-2 job provides a "tax cushion" — regular withholding that covers most of your base tax liability. This makes the multi-state freelance piece more manageable because you're typically only dealing with incremental taxes on the freelance income.
Key takeaway: Your W-2 withholding covers most of your tax liability, so focus on tracking and paying taxes on freelance income in each state where you exceed filing thresholds.
Key Takeaway: Your W-2 withholding provides a tax cushion, so focus quarterly payments and multi-state filings on just the incremental taxes from freelance income.
