1099 Contractor in South Dakota with a Wyoming Client: Where Do You File?
Answer
Nothing is due to either revenue department. Self-employment income is sourced to where the services are performed, which is South Dakota — a state with no wage or earned-income tax — and Wyoming taxes no such income either.

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: Wyoming has no personal income tax, and neither does South Dakota.
What you file
There is nothing to file in either South Dakota or Wyoming on these wages. Your federal return is unaffected — the federal government taxes the income whatever the states do.

Questions people actually ask
I live in South Dakota and my client is in Wyoming. Do I have to file a Wyoming tax return?
Nothing is due to either revenue department. Self-employment income is sourced to where the services are performed, which is South Dakota — a state with no wage or earned-income tax — and Wyoming taxes no such income either.
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 South Dakota and Wyoming hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
