Can I claim my AI subscription?
The work-related share of a subscription you use to earn your income is a general deduction. Keep a record that shows how you worked out that share. The private share stays out of the claim.
The questions you'd save up for your accountant
What can I claim this year?
It lists the deduction categories that can fit how you work, such as home office, equipment and software, each with the ATO source behind it. You decide what to claim.
How do I write off my new laptop?
It shows which write-off rules can apply to your structure. Employees can claim many items costing $300 or less straight away, and small businesses check the instant asset write-off threshold for the year. It runs the numbers and cites the rule it used.
Is anything in my return risky?
It checks your return against the risk areas the ATO publishes and shows where you stand. This year you sit comfortably in the low band.

Before you connect
Is this tax advice?
No. Australian Tax MCP retrieves published ATO material and runs fixed calculations, always with the source attached. Confidence ratings and risk bands are guides, not professional judgement. Your AI agent does the reasoning, and decisions that matter should still go past a registered tax agent.
What does Australian Tax MCP store about me?
Your tax profile (the 23 fields you control), your sign-in identity and your lookup counts. We never store your questions or the answers. We log which tool ran and when, which library documents it returned each day (IDs only, to spot bulk copying), and the name and version of your AI app. The privacy page lists what is kept and for how long.
Which AI agents does it work with?
Any AI agent that speaks the Model Context Protocol: Claude, ChatGPT, Codex, Gemini CLI, Cursor, VS Code and more. One line to install, then sign in with your browser.
Is there an MCP server for Australian tax?
Yes. Australian Tax MCP is an MCP server for Australian tax: it gives any AI agent that speaks the Model Context Protocol (Claude, ChatGPT, Codex, Gemini CLI, Cursor, VS Code) cited retrieval over 34,500+ ATO documents, the income tax and GST Acts and 4,900+ public rulings.
What is MCP (the Model Context Protocol)?
MCP is the open standard AI agents use to call outside tools and data sources. Australian Tax MCP uses it to give your AI agent 13 Australian tax tools: search over the corpus, statutory definitions, current rates and thresholds, and four workflow tools, with every answer carrying its ATO citation.
How current is the corpus?
It is built from ato.gov.au, the Federal Register of Legislation and law.ato.gov.au. Refreshed monthly. The stats tool reports the live snapshot.
Is it open source?
Most clients connect directly to the hosted endpoint with no local code at all. The optional npm client is open source (AGPL-3.0) and public, so you can verify exactly what it does. The hosted retrieval platform and the corpus are maintained privately.
How much does it cost?
Free for 25 lookups a month with every tool included. Pro is $499 once for lifetime, or $25 a month ($300 a year), including GST, for unlimited lookups. Lifetime means for as long as Australian Tax MCP runs. Cancel online any time, and your first Pro payment is refundable for 14 days.
