Tax research

Cut hours of research to minutes. Get answers you can actually trust.

  • ✓Research that used to take an hour, done in minutes. Ask in plain English and get a fully cited answer — ready to review, check, and send to a client.
  • ✓Every answer is traceable. Sourcemark cites the exact clause, ruling, or file behind each claim — not a general reference, the specific passage. You can check it before it goes anywhere.
  • ✓No hallucinations. Unlike general AI, Sourcemark cannot reach outside your knowledge base. It won't invent an answer or cite a source that doesn't exist.
  • ✓Factor in your client's situation. Upload a prior-year return, an invoice, or a lease — it gets cited alongside the legislation in the same answer.

How we compare

Not another Copilot tab.

Copilot and ChatGPT are fast, but they guess at legislation and case law. Sourcemark doesn't guess — and lets you control exactly what it's allowed to answer from.

Built for firms that handle sensitive client data. Sourcemark only ever cites sources from your own knowledge base — it cannot generate answers from outside it. Files you upload are used by your experts only and never shared with other accounts or used to train external models. We're in early beta: if security documentation matters to your firm before signing up, contact us and we'll prioritise it.

FAQs

More about Sourcemark

How is this different from just uploading files to ChatGPT?

A generalist chatbot answers every question the same way, regardless of who's asking or what your firm's actual position is. Sourcemark's experts are scoped and named to one issue, and only draw on the sources assigned to that expert — legislation, rulings, and your own firm's materials — so the answer reflects your practice, not a generic pass over the internet.

Can we build more than one expert?

Yes. Three are ready on day one — Rental Deductions, Division 7A, and Trust Distributions — and you can build as many more as your practice needs: FBT, R&D, payroll tax, SMSF, or anything else you research often.

What happens to our uploaded client files?

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 security note above for more detail.

Is this only for tax, or other compliance areas too?

Tax is where we're starting, but the same build-your-own-expert approach works for any narrow, source-heavy compliance problem your firm deals with repeatedly.

What does early access actually include?

Free access for the full beta period, the three pre-loaded experts, direct input into what we build next, and a single email when your invite is ready — no spam.

Better research. Faster answers. Every week.

Slow, uncheckable tax research costs your firm time every week. Sourcemark gives you cited answers in minutes — so you spend less time searching and more time advising.
