Important: NY & CA Aggressive Sourcing Rules
New York applies the "convenience of the employer" rule — if you work remotely for a NY-based employer or client for your own convenience (not because the employer required it), NY may claim tax on all your income, not just the NY-sourced portion. This estimate uses only your NY-sourced income; your actual NY liability could be higher.

How multi-state taxation works
As a remote freelancer, your home state taxes your entire income. But if you earn income sourced to another state — by working for a client located there or physically performing work there — that state can also tax that portion of your income. To avoid fully double-taxing you, most states offer a credit for taxes paid to other states, which reduces (but may not eliminate) your home state bill.
Note: "Sourced income" rules vary. Some states use where the work is performed; others use where the client is located. This tool uses the income you assign to each state — consult a CPA for your actual nexus.
Estimates only — not tax advice. State sourcing rules are complex and vary by state. This tool uses flat effective rates and a simplified credit model. Consult a CPA or tax professional for your actual multi-state liability.
