Taxes for travel nurses

We have countless clients that are travel nurses & are happy to assist. Some common issues involve:

• What jurisdiction will be considered my “tax home” and what are the tax implications of this decision? 
• How do I avoid double taxation if I have worked in multiple states?
• What deductions apply to my situation? Can I take a “per diem” deduction for food & miscellaneous items? 
• Can I itemize my expenses or take deductions for travel or lodging? 
• Are professional licenses, etc. deductible? 
• What is better – being paid on a 1099 or a W2? 
• Do quarterly taxes apply to me? 
• Should I file jointly or separately with my spouse? 
• What are tax savings strategies if I have multiple employers in one year?
