You do not have to submit any returns not established in any of these states if you live in D.C. Employees must require you to deduct taxes for their country of origin and not for their state of work. Reciprocal tax treaties allow residents of one state to work in other states without tax being deducted from their wages for that state. They would not have to file undeed public tax returns, provided they follow all the rules. You can simply provide your employer with a necessary document if you work in a state that has reciprocity with your home country. Stop paying taxes on an employee`s state of work if your employee gives you their state exemption form. Then start with the deduction for the employee`s home state. .
