Tax research software
Tax research software should save the hours spent searching scattered official sources without asking you to trust an unsourced summary. TaxOrch searches legislation, guidance and case law, ties every statement to the section it rests on, and says plainly when the sources it holds do not answer the question, instead of guessing.
How TaxOrch does it
Ask in plain language
Describe the question and the jurisdiction; TaxOrch searches the official sources it holds for that country.
Statements with their source
Each finding shows the publication and section it rests on, one click from the text itself.
No answer without proof
Where the sources do not settle the question, the result says so and suggests the next step.
Ready for a working paper
Findings are kept with their sources, so a reviewer can check them and file them with the engagement.


One research question, start to finish
A reviewer asks when a Canadian corporation's T2 return is due when its year ends on 31 March.
- Question
- When is the T2 return due for a 31 March year-end?
- Answer
- By 30 September: the last day of the sixth month after the tax year ends.
- Source
- Canada Revenue Agency, ‘When to file your corporation income tax return’
- Review
- The reviewer opens the source, accepts the finding and files it with the engagement.
- Output
- A cited finding in the workpapers, with the reviewer and the date recorded.
Illustrative. The product shows the source and its date beside every finding.
What it does not do
- It does not file returns or move money.
- It does not answer for a country or topic it holds no source for; it says so.
- It does not replace a professional's judgement on an unsettled point.

Questions buyers ask
Where does TaxOrch's tax research come from?
From official publications collected from the tax authorities and legislatures themselves, versioned so an answer can be traced to the exact text used.
What happens when the law is unclear?
TaxOrch states that its sources do not answer the question precisely and points to the next step, rather than producing a confident but unsupported answer.
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.
