What is the difference between an HSN code and a SAC code?

HSN (Harmonized System of Nomenclature) codes are used to classify tangible goods and physical commodities, whereas SAC (Services Accounting Code) codes are used to categorize services under the Indian GST system.

How many HSN digits are mandatory on GST tax invoices?

Businesses with an Aggregate Annual Turnover (AATO) up to ₹5 Crore must report a minimum of 4 digits for B2B supplies (optional for B2C). Businesses with AATO above ₹5 Crore must mandatorily report a 6-digit HSN code for all B2B and B2C transactions. Export and import transactions require an 8-digit code.

What are the standard GST rate slabs in India?

The primary GST tax rate slabs in India are 0% (exempt/essential goods), 5% (basic necessities), 12% (standard processed items), 18% (most capital goods and professional services), and 28% (luxury items, sin goods, and automobiles).

2. Difference Between HSN and SAC

GST classifies supplies into two distinct categories:

HSN (Harmonized System of Nomenclature): Multi-purpose 6-to-8 digit system developed by the WCO for tangible goods (Chapters 01 to 98).
SAC (Services Accounting Code): India-specific 6-digit classification created by CBIC for services. All SAC codes uniformly begin with the digits 99.

Mandatory HSN Digit Rules (Based on Turnover Thresholds)

Under GST Notification No. 78/2020 – Central Tax, businesses must declare a minimum number of HSN digits on tax invoices according to their Aggregate Annual Turnover (AATO):

Annual Turnover (AATO)	B2B Tax Invoices	B2C Tax Invoices	Import / Export Shipments
Up to ₹5.00 Crore	4 Digits Required	Optional (Recommended)	8 Digits Required
Above ₹5.00 Crore	6 Digits Required	6 Digits Required	8 Digits Required

Frequently Asked Questions About HSN & SAC Codes

Clear answers to common questions about GST classifications, invoicing compliance, and tax rates in India.

HSN (Harmonized System of Nomenclature) is used for the categorization of physical goods and merchandise, containing chapters from 01 to 98. SAC (Services Accounting Code) is used exclusively for intangible services under GST, and every SAC code uniformly starts with the number 99 (e.g., 9983 for Information Technology and Professional Engineering Services).

Digital marketing services—including Search Engine Optimization (SEO), Answer Engine Optimization (AEO), Generative Engine Optimization (GEO), website design, social media marketing, and IT consultancy—fall under SAC code 998311 or 998314 and attract 18% GST. Businesses registered under GST can claim a 100% Input Tax Credit (ITC) on this GST amount against their output tax liability.

Quoting an incorrect HSN or SAC code can result in:

Notice of tax mismatch during GSTR-1, GSTR-2B, and GSTR-3B auto-reconciliation.
Denial or temporary blockage of Input Tax Credit (ITC) for your registered buyer.
General penalty under Section 125 of the CGST Act (up to ₹25,000 CGST + ₹25,000 SGST) for issuing non-compliant tax invoices.

No. Effective April 1, 2021, 2-digit HSN reporting has been completely phased out for B2B supplies. Taxpayers with an aggregate turnover up to ₹5 Crore must report at least 4 digits on all B2B tax invoices. For B2C supplies, reporting remains optional for businesses under ₹5 Crore turnover, though maintaining 4 digits is advised for inventory standardization.

Yes. Regardless of annual turnover, all goods exported outside India or imported into the country must carry the full 8-digit tariff code on invoices, shipping bills, and bills of entry. For service exports, the standard 6-digit SAC code starting with 99 is sufficient.

The total GST rate tied to the HSN code remains identical regardless of destination, but the collection mechanism differs:

Intra-state (within same state): Split equally into CGST (half) and SGST (half). For example, an 18% HSN item splits into 9% CGST + 9% SGST.
Inter-state (between two different states or export): Charged fully as IGST (18%).
