High-tax state traps for remote workers
Remote workers face unique challenges with high-tax states, especially those with "convenience of employer" rules that tax you even if you don't live there.
Convenience of employer states to avoid
These states may tax your income even if you're not a resident:

4. Consider contract work: 1099 contractors have more flexibility in tax planning
