No filing is ever submitted on AI work alone. Each piece is reviewed and signed by a licensed professional qualified in the relevant jurisdiction:
Humans file, sign, send and pay — always. Our AI agents prepare everything to a "ready for sign-off" standard; a licensed professional makes the final call.
We never guess a figure: rates, thresholds and deadlines are verified against official sources (IRS, HMRC, the UAE Federal Tax Authority) before they inform your work. Risk and ambiguity are escalated to a human, not buried. Your data is isolated and encrypted.
