Frequently asked questions
Does forming an LLC lower my taxes? +
No, not by default. A single-member LLC is taxed exactly like a sole proprietorship — all profit passes through to your personal return and is subject to the same 15.3% self-employment tax. The only difference is the state LLC fee added on top.
Why form an LLC if it doesn't save on tax? +
Liability protection, not tax savings — an LLC separates your personal assets from business debts and lawsuits. Tax savings only come from a separate choice: electing S-corp taxation on top of the LLC.
Can an LLC elect S-corp taxation? +
Yes. An LLC can file to be taxed as an S-corp, which can reduce self-employment tax on the profit above a reasonable salary. See our S-corp election calculator to check whether that trade-off is worth it for your numbers.
What's the LLC fee based on? +
It varies entirely by state, from $0 to $800 per year, structured either as a flat franchise tax (like California's $800 minimum) or an annual or biennial report fee.
Do I have to pay the LLC fee even with no profit? +
Usually yes — most state LLC fees are flat regardless of income. California's $800 minimum franchise tax is the best-known example of a fee owed even in a loss year.
What does Colorado charge for an LLC? +
Colorado charges a $25 annual LLC fee. Periodic report due in a 5-month window around your formation anniversary.
