About StructureCost

StructureCost shows what a sole proprietorship, an LLC, an S corp and a C corp cost a year in each US state, so an owner can see when changing structure pays before talking to anyone.

The calculator runs in your browser. Nothing you type into it is sent anywhere unless you fill in the contact form.

When the numbers show a cheaper structure, an owner can ask to hear from an accountant. It is free for the owner. The site may earn from the accounting firms it works with, and the figures stay the same either way: they come from the published rates linked on each page.

StructureCost is a Moltke Benjaminsen Alpha project, run by Moltke Benjaminsen ApS. Contact: hello@structurecost.com.
