Do freelancers need to register for GST?

GST registration is mandatory if your annual turnover from freelance services exceeds ₹20 lakhs (₹10 lakhs if you're in a special category state like Manipur, Mizoram, Nagaland, Tripura, etc.).

Even if you're below this threshold, voluntary registration makes sense if:

→You invoice international clients and want to claim export benefits (zero-rated supplies)
→Your clients are GST-registered businesses who need to claim Input Tax Credit (ITC)
→You want to claim ITC on your own business expenses like software, laptop, office rent

Note: If you make interstate supplies (client in a different state than you), GST registration is mandatory regardless of turnover.

Mandatory fields on a GST invoice — Rule 46, CGST Rules

Under Rule 46 of the CGST Rules, every GST invoice must contain these fields. Missing even one can result in your client losing their ITC claim — and you facing a penalty of ₹1,000 to ₹25,000 per invoice.

Field	Details	Required
Your name / business name	Exactly as registered on GST portal	✅ Mandatory
Your complete address	Including state and PIN code	✅ Mandatory
Your GSTIN	15-digit GST Identification Number	✅ Mandatory
Invoice number	Unique sequential — e.g. INV-2026-001. Reset each financial year.	✅ Mandatory
Invoice date	Date of issue in DD/MM/YYYY format	✅ Mandatory
SAC code	Service Accounting Code for your specific service	✅ Mandatory
Description of services	Clear description of work done	✅ Mandatory
Taxable value	Amount before GST	✅ Mandatory
GST rate & amount	CGST + SGST (intra-state) or IGST (inter-state)	✅ Mandatory
Total amount payable	Including all taxes	✅ Mandatory
Client's name & address	Full billing address	✅ Mandatory
Client's GSTIN	Required for B2B invoices — allows client to claim ITC	B2B only
Place of supply	State where service is consumed	✅ Mandatory
Signature	Physical or digital signature	✅ Mandatory

SAC codes for freelancers — profession-wise list

The SAC (Service Accounting Code) identifies the type of service you provide. It's mandatory on every GST invoice issued to a B2B client (from April 1, 2021). Here are the most common codes for freelancers:

Profession	SAC Code	GST Rate
Web / App Developer	998314	18%
Graphic / UI Designer	998392	18%
Content Writer / Copywriter	998439	18%
Business / Management Consultant	998312	18%
Social Media Manager	998361	18%
Digital Marketing / SEO	998361	18%
Video Editor / Animator	999612	18%
Photographer	999612	18%
Accountant / CA Services	998222	18%
Other Professional Services	9983	18%

* Most freelance services attract 18% GST. If your exact service isn't listed, SAC 9983 (Other professional, technical and business services) is the safe default. Consult your CA if unsure.

CGST vs SGST vs IGST — which one to charge?

This is where most freelancers get confused. The rule is simple:

Same state as client

CGST + SGST

You're in Bangalore (KA), client is in Mysore (KA) → CGST 9% + SGST 9%

Different state than client

IGST

You're in Bangalore (KA), client is in Mumbai (MH) → IGST 18%

International client

0% (Zero-rated)

Client is in USA, UAE, UK etc. → 0% GST. File LUT annually to avoid charging GST.

Important: The "place of supply" for services is generally the state where the client (recipient) is located — not where you are. If your client is in Maharashtra and you're in Karnataka, it's an inter-state supply → charge IGST.

Invoicing international clients — zero-rated exports & LUT

If your client is outside India, your service qualifies as export of services under Section 2(6) of the IGST Act — and is zero-rated. You do NOT charge GST.

To export without paying GST, you must file a LUT (Letter of Undertaking) on the GST portal each financial year. It's a simple online form (RFD-11) — takes 5 minutes, approval is usually instant.

Export invoice — mandatory extra fields:

✦Zero-rated declaration: "Supply meant for export under LUT without payment of IGST"
✦LUT number & date: E.g. LUT No. RD2704250012345 dated 01/04/2025, valid till 31/03/2026
✦Place of supply: "Outside India, [Country Name]"
✦Client's foreign address: Full legal name and complete billing address
✦Amount in foreign currency: Plus INR equivalent with RBI rate and date
✦SAC code: Same as domestic invoices

After payment: Get your e-FIRA (Foreign Inward Remittance Advice) from your bank. This is proof that you received foreign currency — needed for GST return filing and any ITC refund claims. Most banks generate it automatically; if not, request it within a few days of receiving payment.

5 common GST invoice mistakes freelancers make

❌ Using CGST+SGST for an inter-state client

✅ Fix: Always check the client's state. If they're in a different state than you → IGST. Same state → CGST + SGST.

❌ Missing or wrong SAC code

✅ Fix: From April 2021, SAC code is mandatory for B2B invoices. Use the table above to find your code. Wrong SAC can cause GST return mismatches.

❌ Charging GST on international clients

✅ Fix: File a LUT (free, takes 5 min on GST portal) and mark the invoice as zero-rated. You should never charge GST on export invoices.

❌ Not collecting the client's GSTIN on B2B invoices

✅ Fix: Without client GSTIN on the invoice, they cannot claim ITC. This is a common reason clients delay payment or reject invoices.

❌ Reusing or skipping invoice numbers

✅ Fix: Each invoice must have a unique sequential number within a financial year. Gaps or duplicates can trigger a GST audit.

Frequently asked questions

Do freelancers need to charge GST in India?

Yes, if your annual turnover exceeds ₹20 lakhs (₹10 lakhs in special category states). Below this threshold, GST registration is optional — but voluntary registration is worth it if you have B2B clients or international clients.

What SAC code should a freelancer use?

It depends on your profession. Web/IT development: 998314, Graphic design: 998392, Content writing: 998439, Business consultancy: 998312, Social media: 998361. If unsure, use 9983 (Other professional services) as a safe default.

Do I charge GST on invoices to international clients?

No. Services to foreign clients qualify as export of services and are zero-rated. File a LUT on the GST portal each financial year and write "Supply under LUT without payment of IGST" on the invoice.

What is the penalty for a wrong GST invoice?

Penalties under Section 122 of CGST Act range from ₹1,000 to ₹25,000 per invoice. Wrong invoices also prevent your B2B clients from claiming Input Tax Credit, which can seriously damage your client relationship.
