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.

Example request: "My LLC started in March, can I still file Form 2553 for this year and where do I send it from Texas?"

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use FileMyScorp to help me.
