AI tax software for UK accountants
AI tax software for UK accountants has to answer from HMRC and the legislation, not from a model's memory. TaxOrch answers UK questions such as the corporation tax rate or income tax bands with the official source shown, works out withholding on payments abroad, runs client engagements with a reviewer gate, and can carry your firm's own brand.
How TaxOrch does it
Cited UK answers
Rates, bands and allowances answered from official UK sources, with the citation one click away.
Cross-border payments
Withholding on dividends, interest and royalties paid from the UK, with treaty conditions listed.
Client engagements
Intake, documents, research and calculation for each client, with maker-checker review.
Under your brand
A white-label licence puts your firm's name and logo on the app your clients use.

Questions buyers ask
Does TaxOrch use HMRC sources?
Yes. UK answers cite the official publication they rest on, and the source is shown with every figure.
Can a UK firm offer it to clients under its own brand?
Yes, through the White-label licence: your name, logo, colours and web address on the client app.

Not a demo of a happy path — a real matter, worked through to a pack, so you can look at what a reviewer would actually see and decide whether it holds.
Decision support, not tax advice. A professional reviews before anything is filed.
