For most mental health counselors and therapy practices, the IRS business code is 621330 – Offices of Mental Health Practitioners (except Physicians). This code is commonly used for counseling, therapy, and behavioral health services.
If your business primarily provides mental health counseling, this is often the appropriate classification. For example, NuTrans Health offers professional mental health counseling and behavioral health services, which generally fall under this category. You can learn more at NuTrans Health.
If you're unsure, it's always best to confirm the correct code with a tax professional or the latest IRS guidance.
