Day Counting Rules for Puerto Rico tax residency
Accurate day counting is essential for US citizens establishing Puerto Rico tax residency. Generally, any part of a day spent in Puerto Rico counts as a full day, with some exceptions for transit. Days spent outside Puerto Rico due to a medical condition that arose while on the island may count towards your presence test. Maintain detailed records of your travel, including flight information, accommodations, and reasons for any absences. This documentation is crucial if your residency status is questioned by tax authorities. Remember, while Puerto Rico residents are US citizens, they are subject to different tax rules than mainland residents.
