What Form 2553 is
irs.gov says a corporation, or another entity eligible to be treated as a corporation, files this form to make an election under section 1362(a) to be an S corporation. The IRS instructions say that an entity eligible to elect to be treated as a corporation that meets certain tests is treated as a corporation as of the effective date of the S election and does not need to file Form 8832. RepeatForm cannot tell you whether you should elect or whether you qualify.
