FAQ

Sole Proprietor Accountants in Phoenix

Do I need an accountant as a sole proprietor?

If you earn over ~$30K from self-employment, an accountant typically pays for themselves by capturing missed deductions and keeping you in quarterly safe-harbor.

When should a sole proprietor become an LLC or S-Corp?

An LLC is worth it once liability exposure matters; an S-Corp election typically saves self-employment tax once net profit consistently exceeds ~$50K.
