1099 Contractor in Alaska with a Missouri Client: Where Do You File?
Answer
Missouri only, and only for on-site work. Nothing is withheld from a 1099, and Alaska levies no income tax, so the single question is whether any of the services were performed in Missouri. If none were, no Missouri nonresident return is required.

Two things make this pairing simple. Alaska levies no personal income tax, so there is no resident return; and Missouri taxes nonresidents only on services actually performed inside Missouri, which for a fully remote contractor is normally nothing.
Missouri publishes no de minimis day count or dollar floor for nonresidents. Any Missouri-source wage income above the state's general filing threshold requires a nonresident return, and that threshold is reset each year — check the current figure on the Missouri Department of Revenue nonresident instructions before filing.

The other direction

Same two states, different situation

Questions people actually ask
I live in Alaska and my client is in Missouri. Do I have to file a Missouri tax return?
Missouri only, and only for on-site work. Nothing is withheld from a 1099, and Alaska levies no income tax, so the single question is whether any of the services were performed in Missouri. If none were, no Missouri nonresident return is required.
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 Missouri hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
