How Your Return Is Prepared
Every return is prepared by our Enrolled Agent, who reviews each form for accuracy before signing and filing. The process begins with a secure document upload through our client portal, followed by a detailed review of your income sources, treaty positions, and available exclusions or credits. Your return is prepared in-house and never outsourced. You receive a draft for your review before we file, and our Enrolled Agent is available to answer questions at every step.
