1099 Contractor in Missouri with a Maine Client: Where Do You File?

Home state, plus the client state if you work thereNo withholding — 1099

Answer

Pay Missouri by instalments, and watch your Maine days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. Missouri taxes the full profit, Maine taxes the on-site share, and the Missouri credit reconciles them.

Reciprocity agreements are the first thing contractors ask about and the first thing that does not apply to them. Every agreement in the country is a wage-withholding arrangement, and a 1099 has no withholding to switch off.

Maine publishes a genuine de minimis for nonresidents — roughly 12 days of work in the state, alongside a dollar floor — below which the income is not taxed there. Maine publishes a genuine de minimis: a nonresident who performs personal services in Maine on 12 or fewer days AND earns under the published dollar floor from Maine sources owes no Maine tax on those wages. Exceeding either test brings the whole amount into Maine.

Questions people actually ask

I live in Missouri and my client is in Maine. Do I have to file a Maine tax return?

Pay Missouri by instalments, and watch your Maine days. Reciprocity agreements do not help here: every one of them covers wage withholding, and a 1099 has no withholding to switch off. Missouri taxes the full profit, Maine taxes the on-site share, and the Missouri credit reconciles them.

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 Missouri and Maine hold an agreement makes no difference to a self-employed filer — sourcing rules decide the answer instead.
