Based on my experience, and our company has a lot of remote workers, income is always taxed based on the state in which the work is done, not where the employer is located. Depending on state laws, technically they might expect you to file a nonresident return even if you work from another state while traveling (although that might also be hard to prove or enforce). From https://www.britannica.com/money/tax-residency-status:
+1 I traveled a lot across the US for work and for our timesheets we had to include a location code that was used for state income tax purposes. One year I had to file 9 state income tax returns. The firm provided us all with a free version of TurboTax to make it easier.
