Form 2553
The IRS describes Form 2553 as the form a corporation or eligible entity files to make an S corporation election under section 1362(a). The form asks for entity facts, effective date, tax year, officer signature, and shareholder consent information.
Form 8832
The IRS describes Form 8832 as the entity classification election for an eligible entity to be classified as a corporation, partnership, or disregarded entity. That choice can affect federal tax consequences, so the preview treats the choice as already made outside the software.
When to stop
Do not use a browser-local packet to decide between S corporation status, C corporation status, partnership status, or disregarded status. That is tax and entity planning, not clerical form filling.
