FAQ
Sole Proprietor Accountants in Massachusetts
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.
