1099 Contractor in Wyoming with a Washington Client: Where Do You File?
Answer
A clean pair for a contractor. With no personal income tax in Wyoming or Washington, the state layer disappears: no estimated payments, no nonresident return, and no question about whether the client's location creates a filing obligation.

The recurring 1099 question is whether a client in another state drags you into that state's tax system. Here the question is doubly moot: Washington has no personal income tax, and neither does Wyoming.
What you file
There is nothing to file in either Wyoming or Washington on these wages. Your federal return is unaffected — the federal government taxes the income whatever the states do.

The other direction

Same two states, different situation

- Remote worker: Wyoming → WashingtonNo state income tax either side
- Moved mid-year: Wyoming → WashingtonNo state return either side

Questions people actually ask
I live in Wyoming and my client is in Washington. Do I have to file a Washington tax return?
A clean pair for a contractor. With no personal income tax in Wyoming or Washington, the state layer disappears: no estimated payments, no nonresident return, and no question about whether the client's location creates a filing obligation.
Do reciprocity agreements help a 1099 contractor?
No. Every state reciprocity agreement in the country is an arrangement about wage withholding between two revenue departments, and a 1099 has no withholding to switch off. Whether Wyoming and Washington hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
