The TCO of a company depends heavily on your situation, which is one reason we find it difficult to have an official answer on that. As a single data point, my personal tax situation involved US LLCs last year, as an American living in Japan. I spent about ~$10k on accountants to file taxes in both countries plus bookkeeping services. That's towards the high end among my friends; that's nowhere near the high end for "total amount spent on accountants in a year." For comparison, Atlas would have introduced me to an accounting firm offering the US side of that for ~20% of what I ended up spending on it. (This is difficult to do an apples-to-apples comparison even in this case, because C Corp vs LLC, but trust me when I say "I was pleasantly surprised where we got the numbers to.") We're working on having an even better offering here for next year. We'll have more to say that closer to tax season 2017.
