Answers on the IRS S corp election, plus deadline math and where to send Form 2553.
Covers IRS Form 2553: eligibility, the on-time and late-election deadlines, shareholder consent, state-level elections, and the IRS office, fax and mailing address for your state. Muse can also estimate the tax effect of electing S corp status and find FileMyScorp's guides and filing service.
Try asking Muse: "My LLC started in March, can I still file Form 2553 for this year and where do I send it from Texas?"

FileMyScorp is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
