You pass the test if, just before the CGT event, the net value of the CGT assets of you, your connected entities, your affiliates and entities connected with them doesn’t exceed $6 million [1]. It’s an alternative to being a CGT small business entity, and the asset must also pass the active asset test [2].

How to add Nylon to Microsoft Copilot
Microsoft 365 Copilot can’t take an MCP URL directly. One person builds a Copilot Studio agent with Nylon as a tool, then shares it with colleagues.
For the agent maker
In Copilot Studio, create an Agent (Standard) and name it, for example Nylon Research.
Paste the instructions from the setup guide, and set generative orchestration to Yes.
Choose Tools → Add a tool → Add new MCP, name it Nylon Library and paste the URL below.
Choose OAuth 2.0 and Dynamic discovery, create a connection, sign in to Nylon and choose Allow access.
In the tool’s settings, choose End user credentials.
Publish the agent, then share it with your colleagues.
MCP server URL
https://mcp.usenylon.com/mcp
Each colleague then adds the agent in Microsoft 365 Copilot and signs in to Nylon the first time they use it.
For colleagues
In Microsoft 365 Copilot, choose Agents, find the Nylon agent and choose Add. In a new chat, type @ and its name. The first time, choose Open connection manager and connect to Nylon.
Use end-user credentials
With maker-provided credentials, everyone runs as the maker’s Nylon account, so one seat is shared across the firm. End-user credentials make each colleague sign in as themselves.

Nylon for Microsoft Copilot: frequently asked questions
More detail is in the Copilot Studio setup guide, or email support@usenylon.com.
Which Microsoft licences do I need?
The maker needs Copilot Studio access: a Copilot Studio user licence, which your Microsoft 365 admin assigns at no cost, the Copilot Studio authors role, or a Microsoft 365 Copilot licence. A trial can build and test an agent but can’t publish it. Colleagues use the agent in Copilot Chat.
Which Nylon plan do I need?
An Adviser or Elite seat for everyone who uses the agent. Starter seats don’t include the AI connector.
What Australian sources can Copilot search?
Australian legislation, ATO rulings and guidance, and federal and state case law.
How is this different from asking Copilot about Australian tax directly?
On its own, Copilot answers from its training data, your Microsoft 365 content and, if your organisation allows it, the web. With Nylon, the agent searches a curated library of primary sources, reads the documents and links each citation to the source so you can check it.
Can Copilot change anything in Nylon?
No. The Nylon tools are read-only. Copilot can search and read documents, but it can’t upload, edit or delete anything, or see your chat history, folders or saved work.
Why do I need a Copilot Studio agent?
Microsoft 365 Copilot can’t take an MCP server URL directly. A Copilot Studio agent holds Nylon as a tool, and one maker can share it with the whole firm.
Does it work in Microsoft Teams?
Not yet. Use the agent in Microsoft 365 Copilot Chat. Microsoft also publishes agents to Teams, but Nylon doesn’t support the Teams chat surface yet, and it may keep asking you to connect.
Does Nylon charge for Copilot use?
No, and it doesn’t use Pro credits. On the Microsoft side, agent use by people without a Microsoft 365 Copilot licence is metered in Copilot Credits through your tenant’s Copilot Studio capacity or pay-as-you-go billing.
How do I disconnect Nylon from Copilot?
The maker can remove the Nylon tool from the agent. A Nylon admin can turn off Allow AI tool connections for the whole organisation, or move a person to a Starter seat.
