GST Invoicing Guide for Freelancers in India: Rules, Rates & Templates

GST Registration Thresholds: When Do Indian Freelancers Need GSTIN?

Under Indian tax regulations, service providers must register for GST under specific turnover and operational conditions: 1. The General Turnover Limit (₹20 Lakhs) For freelancers providing services within India, GST registration is legally mandatory once your aggregate annual turnover exceeds ₹20 Lakhs in a single financial year (from April 1 to March 31). If your business operates in special category states (such as Manipur, Mizoram, Nagaland, and Tripura), the threshold limit is ₹10 Lakhs. Your aggregate turnover includes all taxable supplies, exempt services, and export of services. Even if your foreign client earnings are zero-rated, they count toward this ₹20 Lakh threshold. 2. Mandatory Registration for Inter-State Supplies (With Exceptions) Historically, any person making an inter-state supply of services (billing a client located in a different Indian state) was required to register for GST regardless of turnover. However, under Notification No. 10/2017 - Integrated Tax, service providers whose aggregate turnover does not exceed ₹20 Lakhs (or ₹10 Lakhs in special category states) are exempt from mandatory registration even if they supply services across state lines. 3. Voluntary Registration: Why Some Freelancers Register Early Even if your annual revenue is below ₹20 Lakhs, voluntary GST registration offers distinct strategic advantages:

• Corporate Client Eligibility: Many mature enterprises and Indian agencies refuse to hire unregistered freelancers because they cannot claim Input Tax Credit (ITC).
• Input Tax Credit (ITC) Deductions: A GST-registered freelancer can claim ITC on essential business expenses — including laptop purchases, software subscriptions, office equipment, and cloud hosting bills.
• Enhanced Commercial Credibility: Displaying a valid GSTIN on your quotes and proposals conveys operational maturity and enterprise readiness.

Calculating Rates: CGST + SGST vs IGST for Domestic Clients

Once registered, you must apply the correct GST rate and tax component to every domestic invoice based on the location of your client: The Standard Freelance GST Rate (18%) The vast majority of freelance knowledge work falls under SAC Code 9983 (Other Professional, Technical, and Business Services), which includes: The standard GST rate for these professional services is 18%. Determining Intra-State vs. Inter-State Supply The tax split depends on the Place of Supply relative to your registered location: 1. Intra-State Supply (Client in the Same State): If both you and your client are located in the same state (e.g., both in Maharashtra), you divide the 18% tax equally between Central GST and State GST: 2. Inter-State Supply (Client in a Different State): If your registered address is in Karnataka and your client's registered office is in Delhi, you charge Integrated GST: Here is a quick reference table for billing domestic Indian clients:

• Software development, UI/UX design, and IT consulting
• Graphic design, branding, and video editing
• Copywriting, content strategy, and technical translation
• Digital marketing, SEO, and paid advertising management
• CGST: 9%
• SGST: 9%
• Total: 18%
• IGST: 18%

Export of Services: How Indian Freelancers Bill Foreign Clients with Zero GST (LUT Guide)

One of the most common points of confusion for Indian freelancers is whether to charge 18% GST to international clients based in the US, UK, Canada, or Singapore. Under Section 2(6) of the IGST Act, the supply of services to an overseas recipient qualifies as an "Export of Services" and is treated as a Zero-Rated Supply, provided five conditions are satisfied: 1. The supplier of service is located in India. 2. The recipient of service is located outside India. 3. The place of supply of service is outside India. 4. The payment for such service has been received in convertible foreign exchange (or in Indian Rupees wherever permitted by RBI, such as via approved payment gateways). 5. The supplier and recipient are not merely establishments of a distinct person. How to Bill Foreign Clients Without Paying 18% Tax (The LUT Route) You have two legal options when billing foreign clients under GST: You file Form GST RFD-11 (Letter of Undertaking) online once per financial year on the GST portal. It takes approximately 5 minutes and is free. Once filed, you can issue export invoices with 0% GST charged, without locking up your working capital. You pay the 18% IGST upfront from your pocket and subsequently file a refund claim. This route severely strains freelance cash flow and requires extensive paperwork. Mandatory LUT Statement on Export Invoices When issuing an invoice under LUT, you must include this mandatory declaration on the invoice document: > *"SUPPLY MEANT FOR EXPORT UNDER BOND OR LETTER OF UNDERTAKING WITHOUT PAYMENT OF INTEGRATED TAX (IGST)"* Furthermore, always retain your Foreign Inward Remittance Certificate (FIRC) or electronic Bank Realisation Certificate (e-BRC) issued by your bank or payment processor (e.g., Stripe, PayPal, Wise) as proof of foreign exchange receipt for tax audits.

• Option A: Export Under Letter of Undertaking (LUT) — Recommended:
• Option B: Export with Payment of IGST and Claim Refund:
