No filing is ever submitted on AI work alone. Our practice is led by a licensed professional who holds both of the credentials a US–UK cross-border filing needs:
One reviewer, both jurisdictions — which is precisely what a cross-border filing needs: the two returns are prepared to agree with each other, not argue. You will meet the professional who signs your work, and can verify their credentials, at your consultation. Out of personal preference they do not appear in marketing materials; their name, credential and signature appear on your engagement documents and filings — where they matter.
Humans file, sign, send and pay — always. Our AI agents prepare everything to a "ready for sign-off" standard; the 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.
