1099 Contractor in Alaska with a South Dakota Client: Where Do You File?
Answer
Your only obligation is federal. Alaska does not tax the income where you earn it and South Dakota does not tax it where the client sits, so this pairing removes state income tax from a 1099 arrangement completely — self-employment tax and federal income tax still apply.
Last verified
Contractors carry their own tax administration, which usually means quarterly estimated payments to a home state. This pairing removes that layer entirely — neither Alaska nor South Dakota taxes personal income.
What you file
There is nothing to file in either Alaska or South Dakota 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 Alaska and my client is in South Dakota. Do I have to file a South Dakota tax return?
Your only obligation is federal. Alaska does not tax the income where you earn it and South Dakota does not tax it where the client sits, so this pairing removes state income tax from a 1099 arrangement completely — self-employment tax and federal income tax still apply.
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 Alaska and South Dakota hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
