Understanding GST for Freelancers

The Goods and Services Tax (GST) is an indirect tax levied on the supply of goods and services in India. As a freelancer providing professional services, you need to understand how GST works to invoice your clients correctly and remain compliant.

GST Rate for Professional Services

Most freelance and professional services fall under the 18% GST slab. This includes:

  • Software development and IT services
  • Graphic design and creative services
  • Content writing and copywriting
  • Digital marketing and SEO
  • Consulting and advisory services
  • Photography and videography
  • Legal and accounting services

GST Registration Threshold

GST registration becomes mandatory when your aggregate turnover exceeds ₹20 lakhs in a financial year (₹10 lakhs for special category states). Even below this threshold, you can register voluntarily if:

  • You want to appear more professional to clients
  • You want to claim input tax credit on business purchases
  • Your clients require GST invoices
GST Calculation Formula:
GST Amount = Base Amount × (GST Rate / 100)
Total Amount = Base Amount + GST Amount

To extract base from inclusive amount:
Base Amount = Total Amount × (100 / (100 + GST Rate))

CGST, SGST, and IGST Explained

GST in India is divided into three components based on the nature of the transaction:

TypeFull FormWhen ApplicableWho Collects
CGSTCentral GSTIntra-state transactionsCentral Government
SGSTState GSTIntra-state transactionsState Government
IGSTIntegrated GSTInter-state transactionsCentral (shared)
Example: If you're a freelancer in Mumbai billing a client in Mumbai, you charge CGST (9%) + SGST (9%) = 18%. If your client is in Bangalore, you charge IGST (18%) instead.

How to Determine Transaction Type

  • Intra-State: Both you and your client are in the same state
  • Inter-State: You and your client are in different states
  • Export: Client is outside India (zero-rated under LUT/bond)

GST Invoice Requirements

If you're GST-registered, your invoices must include specific details:

  • Your GSTIN (15-digit GST identification number)
  • Invoice number (unique, sequential)
  • Invoice date
  • Client's name and address (GSTIN if registered)
  • HSN/SAC code for your services
  • Description of services provided
  • Taxable value (base amount)
  • GST rate and amount (split into CGST/SGST or IGST)
  • Total amount payable
  • Your signature or digital signature
SAC Code for Freelancers: Most freelance services fall under SAC code 998314 (Other professional, technical, and business services) or 998313 (Management consulting services). Check the appropriate code for your specific service.
