My wife and I lived in Florida for 10 years. We sold our house and since the sale we have been traveling around the country. We have no state, where do we file?

We are just staying in rentals for 1-4 months at a time in different states. For tax purposes, since we no longer have a domicile, what state do we file in? I also am self-employed, so what state do I file that in?

Federal Regulation 26 CFR 301.6362-6 states:

"An individual who becomes a resident of a State pursuant to subparagraph (1) of this paragraph (b), or who is at the beginning of a taxable year a resident of a State pursuant to such provision, shall be treated as continuing to be a resident of such State through the end of the taxable year, unless, prior thereto, such individual becomes a resident, under the principles of subparagraph (1), of another State or a possession or foreign country."

Thus, if you were a Florida resident in the beginning of the year, for tax purposes you remain a Florida resident until you establish residency in another state.

If you have self-employment income, you would file a non-resident tax return in whatever state or states you earned that income (assuming that your self-employment income exceeded the filing threshold for the particular state).
