Frequently Asked Questions
Requirements vary by state and by the services offered. At minimum you will typically need: a state esthetician or cosmetology license for each service provider, a spa or salon establishment license for the business, and a business license from your city or county. If you offer massage therapy, those staff members also need state massage therapy licenses.
In most states, sauna facilities fall under health department regulations rather than cosmetology board rules. You may need a separate health department inspection and permit for the sauna area, especially if it's a public or commercial facility. Some states also have specific temperature and ventilation requirements.
Most spa owners start with an LLC taxed as a sole proprietor or partnership, then elect S-Corp status once net profits exceed $50,000–$70,000/year. The S-Corp election allows you to split income between salary and distributions, reducing self-employment tax. Consult a CPA for personalized advice.
Spa businesses typically see net profit margins of 8–15% once established. Labor costs (40–55% of revenue) and rent (10–20% of revenue) are the largest expenses. Memberships and retail product sales can significantly improve margins.
