An S corp isn't a type of business. It's a tax election, a form you send the IRS, and your Cape Cod LLC can make it without changing a thing on the sign out front.
Why it comes up every fall: a sole proprietor or single-member LLC pays self-employment tax on the whole profit. Once the business elects S corp status, the owner takes a reasonable salary through payroll and the rest comes out as distributions, and the distributions don't carry self-employment tax. On a business that just had a strong summer, that's a real difference in what stays in the account.
Why we don't tell everyone to do it: the salary has to be one you can defend, you're now running payroll for yourself, Massachusetts charges S corps a minimum excise every year whether you made money or not, and switching back isn't a quick undo. Below a certain profit level the extra cost and paperwork eat the benefit. Our rule of thumb for where that line sits is on the blog, along with when to stay an LLC and leave it alone.
