What electing actually requires
An S corporation is not a filing you make once. It is a payroll obligation. You must pay yourself as an employee, withhold and remit payroll tax on a schedule, file Form 941 each quarter, issue yourself a W-2 in January, and file an 1120-S with a Schedule K-1 by 15 March. Missing the payroll requirement is what turns the election into a liability.
To elect for a tax year you generally file Form 2553 within two months and fifteen days of the start of that year — 15 March for a calendar-year business — though late relief under Rev. Proc. 2013-30 is routinely granted with a reasonable cause statement.
Runs the payroll an S corporation is required to run, files the 941s and W-2 automatically, and handles the S-corp owner health insurance reporting that trips most people up in December.
From about $55/month for a single owner-employee
Flat-rate payroll with S-corp support included rather than sold as an upgrade. Usually the cheapest credible option for a one-person corporation.
$40/month plus $6 per person
Forms the entity and acts as registered agent without the upsell funnel. They do not sell your data, which is not a given in this category.
$39 plus state fee, registered agent $125/year
Handles LLC formation and will file the Form 2553 S election alongside it, which saves a round trip if you are starting from nothing.
