Non-resident alien (NRA) tax filing involves assisting individuals who are not U.S. citizens or permanent residents with meeting their tax obligations under U.S. tax laws. The process can be complex, as it requires navigating unique rules and regulations that differ significantly from those for U.S. residents. Non-resident aliens must determine their tax residency status, understand the treaties between their home country and the U.S., and identify the income subject to U.S. taxation. These services aim to simplify the process and ensure compliance while maximizing any applicable deductions or benefits.
