Sound familiar?
Every firm doing tax research hits the same walls. Sourcemark exists because of these four.
I just spent an hour confirming one Div 7A treatment.
Digging through legislation, rulings and case notes for a question that comes up every month.
ChatGPT gave me a citation that doesn't exist.
General AI is fast, but confidently inventing a section reference is a compliance risk, not a shortcut.
I can't tell what the answer's actually based on.
A shared tax knowledge library answers on everything at once — there's no way to know how narrow or relevant its basis really was.
Every AI answer still needs a full manual check.
Reviewing an answer against its real source takes almost as long as researching it from scratch.
How it works
Search, select, and ask — no manual digging, no unbounded AI guessing.
Full-text search across ATO legislation, rulings, determinations and practice statements — the same material you'd otherwise dig through by hand. See exactly what's there before you rely on it.
Save the sections, rulings and guidance relevant to an issue into a Library — a working set you control. Add your own firm files too. A Library can be as narrow as one client's situation, or as broad as your rental-deductions practice.
Turn a Library into a named, reusable expert. Ask it a question in plain English and get an answer that can only ever come from what you gave it — cited to the exact clause or ruling.
Everything you need
Replaces: guessing at citations
Grounded in the ATO's own legislation, rulings and guidance — not a general AI's memory of the internet.
Replaces: the blank search bar
Search the ATO's own material directly, the same way you'd search any legal database — see exactly what's there.
Replaces: copy-pasting into ChatGPT
Build a named expert trained only on the legislation, rulings or files you selected or uploaded — nothing else.
Replaces: re-checking every answer
Every claim links to the exact clause, ruling or section behind it — not a general reference, the specific passage.
Replaces: everyone re-researching the same issue
One expert, one source of truth — your whole team queries the same scoped, cited assistant on the areas you research most.
Replaces: wondering what the AI actually saw
You always know exactly what feeds any given expert — because you're the one who selected it.

FAQs
A generalist chatbot answers from the open internet and often invents citations. Sourcemark is connected directly to the ATO's own legal database — every answer cites the exact section it came from. You can also build a named expert trained only on legislation you select from that database or upload yourself, so you always know exactly what it's allowed to answer from.
Yes. Build as many named experts as your practice needs — Div 7A, Rental Deductions, Trust Distributions, FBT, R&D, payroll tax, SMSF, or anything else you research often. Each one is trained only on the legislation you select from the database or upload yourself.
No unrelated internet access. An expert only ever answers from the sources you've explicitly selected from the ATO database or uploaded yourself — nothing outside that.
Files are used only to answer your firm's questions and are never shared with other accounts or used to train external models. See the note above for more detail.
