Professional Service Classification
Professional services attract 18% GST under these SAC codes:
| Profession | SAC Code | Description |
| Chartered Accountants | 998112 | Accounting, bookkeeping, audit |
| Lawyers/Advocates | 998213 | Legal services |
| Doctors/Healthcare | 998391 | Specialised medical services |
| Consultants | 998311-998399 | Management/business consulting |
Mixed services require apportionment based on the professional income ratio.
Reverse Charge Mechanism (RCM) Rules
Key RCM Impact:
- Legal services to businesses → Recipient pays 18% GST
- Accounting services → Recipient pays under RCM
- Architects, interior designers → Recipient pays RCM
- Arbitration/mediation → Supplier pays forward charge
RCM Process:
- Recipient creates self-invoice
- Pays IGST/CGST+SGST to the government
- Claims ITC if eligible
Registration Threshold for Professionals
- ₹20 lakh aggregate turnover (₹10 lakh special states)
- No threshold if providing services to registered businesses under RCM
- Mandatory registration for interstate supplies
Doctors serving patients directly can remain unregistered below the threshold.
Quarterly Return Scheme (Mandatory)
Professionals must opt for the QRMP scheme:
| Frequency | Returns | Due Dates |
| Monthly | IFF (B2B invoices > ₹50,000) | 13th of the month |
| Quarterly | GSTR-1 | 13th after quarter |
| Monthly | GSTR-3B | 22nd/24th based on the state |
Benefits: Reduced compliance from 24 to 4 returns yearly.
