Do you plan to raise money from outside equity investors, or grant stock options to attract employees?

Venture and angel investors, and standard option plans, are built around C-corporation stock - not LLC units.

Will the business have more than one owner?

The number of owners changes both the default tax treatment and the paperwork you need in place.

Across all owners, do you expect net profit above roughly $80,000 a year after paying the active owners a reasonable salary?

Above that range, an S-corporation election often saves more self-employment tax than it costs in payroll and admin - commonly cited, confirm your numbers.

Have a CPA model an S-corporation election on the LLC or corporation. Form a multi-member LLC and put the economics in an operating agreement.

Does the business carry real liability exposure - customers, contracts, employees, products, premises, or debt - you want kept away from your personal assets?

A liability shield is the main reason to form an entity at all; without exposure, the simplest option can be enough to start.

Do you expect net profit above roughly $50,000 a year after paying yourself a reasonable salary?

For a profitable solo owner, taking part of the profit as distributions instead of salary can cut self-employment tax - once profit clears this rough range.

Have a CPA model an S-corporation election on a single-member LLC. Form a single-member LLC and keep business and personal finances separate.

Are you mainly testing the idea right now - low risk, no employees, and willing to revisit the structure as it grows?

A sole proprietorship is the cheapest way to start, but it gives no liability shield and taxes all profit as self-employment income.

Start as a sole proprietor, but set clear triggers to convert to an LLC. Form a single-member LLC for the liability shield.
