Good question - affiliate marketing income often confuses people on GST treatment. Here is the full picture:
SERVICE CLASSIFICATION: Affiliate marketing income = commission/referral fee for marketing services. This falls under SAC 998371 (Online information and database access or retrieval services) OR SAC 998596 (Other information technology-enabled services). Both attract 18% GST.
GST REGISTRATION: You must register under GST once cumulative turnover in a financial year exceeds Rs 20 lakh (Rs 10 lakh for specified special category states). Registration is mandatory - you cannot remain unregistered after crossing this limit. Apply at gst.gov.in using your Aadhaar, PAN, bank account, and address proof.
ONCE REGISTERED - WHAT TO FILE:
- GSTR-1: Monthly or quarterly (Quarterly filing available if turnover under Rs 1.5 crore). Report your affiliate commission income as outward supplies.
- GSTR-3B: Monthly summary return + tax payment. Pay 18% GST on your commission earnings after deducting eligible ITC.
- Annual return: GSTR-9 if turnover exceeds Rs 2 crore.
ABOUT CUELINKS SPECIFICALLY: Cuelinks is an Indian affiliate network - so your services billed to Cuelinks are B2B domestic services. Cuelinks will ask for your GSTIN once you register. They may issue you a debit note or the payments will appear in your GSTR-2B for reconciliation.
EXPENSE ITC: You can claim ITC on business expenses - internet charges, laptop (if new purchase), software subscripttions with GST invoice. Maintain proper invoices.
COMPLIANCE TIP: Register before you bill the payment that crosses Rs 20 lakh - not after. If you issue a Rs 3 lakh invoice to Cuelinks that pushes you to Rs 22 lakh, GST is due on that invoice but you need GSTIN before issuing it.
