Have Tax Questions? Ask a Tax Expert for Answers ASAP
Hi and welcome to Just Answer!Generally - if you employer doesn't send you specifically to Mexico - and just allows you to what from whatever location you are - there is nothing they need to arrange.However you should be aware that to legally work in Mexico - you should have the right permit issues be the Mexican Government to people who are sponsored by companies in Mexico or foreign companies with Mexican operations, or to persons with specific skills required in Mexico. You still can enter Mexico to work for a foreign company provided that you do not receive any remuneration directly from a Mexican company or subsidiary. If that is correct - you will continue report your tax liability to the US and nothing you will owe to Mexican tax authorities.Because the trip is primary personal - you may not deduct any travel expenses. Based on information provided - neither you nor your employer need anything to arrange for your temporary visit.
