Common questions
Is the first month really free?
Yes. New clients on a monthly accounting or bookkeeping plan pay nothing for the first month. If you are not happy, you can leave without paying. If you stay, payment starts from month 2 at the fixed fee we agreed. Government and filing fees are not included.
Should I form an LLC or an S corporation?
An LLC is simple and flexible; electing S corporation tax treatment can reduce self-employment tax once profits are high enough to pay yourself a reasonable salary. We model both before you decide.
Can a non-US resident form a US LLC?
Yes. Non-residents can own US LLCs; a foreign-owned single-member LLC usually has to file Form 5472 with a pro forma Form 1120 each year.
