For real. My wife picked up travel nursing and it's been a huge life improvement. Just check the taxes in the states you are working in. I have 25 work days in Illinois without income taxes, but all states are different.
There have been some efforts to rationalize this at the federal level but AFAIK they haven't gone anywhere. And some states seem to basically have zero thresholds for this and enforcement for business travel seems to be ratcheting up. Some people are probably going to find that they need to file more state tax returns.
This is gonna be the real challenge for the WFH movement. NYC is trying to get income taxes out of me because I worked for a NYC based company in 2020... even tho I never stepped foot in their state.
