What TaxOrch does, topic by topic
AI tax software for accounting firms and finance teams: every capability on its own page, each shown working on real screens.
Run engagements
AI tax software for accounting firms
TaxOrch runs a firm's tax engagements end to end: intake, documents, cited research, calculation, maker-checker review and professional sign-off.
AI tax document intake
TaxOrch reads client tax documents, receipts and invoices, pulls out each figure with where it came from, and flags what is missing before any work starts.
Automated tax workpapers
Build tax workpapers automatically: a fact file linked to evidence, cited research, calculations and draft deliverables, ready for a reviewer to check.
AI bookkeeping review
Review the books before tax work starts: trial balance, journals and VAT checked, with anything unusual flagged and explained for a person to decide.
Research and calculate
AI tax research with citations
Ask tax questions and get answers that name the official source and tax year behind every figure. When no source supports an answer, TaxOrch says so.
Cross-border withholding tax calculator
Work out withholding on dividends, interest and royalties paid across borders: the payer country's domestic rate, the treaty rate and the conditions to meet.
Tax treaty withholding rates
Look up the treaty rate for dividends, interest and royalties between two countries, with the article, the published rate and the conditions it depends on.
AI tax software without hallucinations
How TaxOrch avoids invented tax figures: rates come from official sources with their year, arithmetic runs on rules, and it refuses when it cannot verify.
Review, control and security
Tax review and sign-off software
Maker-checker review for tax work: every figure and citation checked against its source, a separate reviewer signs off, and changes cancel stale sign-offs.
Tax audit trail software
A complete, tamper-evident record of every tax engagement: facts relied on, evidence behind them, who did each step and when, exportable for your file.
IRS Section 7216 consent for AI tax tools
How TaxOrch handles taxpayer consent for US engagements: the consent is recorded with its exact wording, checked at every step, and revocation stops the work.
Secure AI tax software for firms
Security controls a firm's IT team asks about: single sign-on, roles, periodic access reviews, approved time-limited support access and a tamper-evident log.
Rates and apps
VAT rates by country
Standard VAT and GST rates by country with the official source and year for each, including local names such as IGI, GCT and consumption tax.
Corporate tax rates by country
Corporate income tax rates by country with the official source and year, including combined rates where sub-national taxes apply, for the year you work in.
Income tax rates and bands by country
Personal income tax bands by country with the official source and year: each band's threshold and rate, set out the way a reviewer needs to check them.
Tax assistant mobile app
The TaxOrch mobile app: ask cited tax questions, check treaty and corporate tax rates, and keep up with your workspace from your phone, wherever you work.
Research, compliance and international tax
Tax research software
Tax research software that searches legislation, guidance and case law and ties every statement to its official source, with a plain reply when proof is absent.
Tax compliance software
Tax compliance software that tracks filing obligations and their status, seals every tax decision in a tamper-evident trail and exports proof for an auditor.
Transfer pricing software
Transfer pricing software for firms: an inventory of controlled transactions, the functions, assets and risks analysis, and the method chosen with its reasons.
Pillar Two software for the GloBE minimum tax
Pillar Two data management software: GloBE inputs tagged by standard and quality, entities pooled by jurisdiction, computed only where rules are verified.

Bring one engagement and check the file.
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.
