Understanding HSN Code for Transportation Charges

A single error on your invoice could lead to costly penalty notices and tax filing hurdles. For those in the Indian transport and logistics sector, the SAC code (Services Accounting Code) is the vital link to ensuring your GST is handled correctly.

Using an incorrect code can block your customers’ Input Tax Credit (ITC), trigger audit scrutiny, and result in inaccurate tax payments. Whether you move goods via road, rail, air, or water, the classification rules are precise. This guide simplifies the process: we provide the exact codes you need, explain how GST rates vary based on your ITC preference, and help you maintain seamless compliance on every invoice.

Key transportation SAC codes and GST rates (2026)

The HSN code for transportation refers to the numerical classification system used under GST to identify and tax services related to the movement of goods and passengers across India. Although HSN (Harmonised System of Nomenclature) traditionally classifies physical goods, the same numerical structure—commonly referred to as SAC (Services Accounting Code) in professional practice—is utilised for services.

The primary heading for transport services is 9965. Accurately applying the correct 6-digit code to your tax invoices is essential for precise GST filing, determining the appropriate tax rate, and ensuring your business remains fully compliant with the latest tax regulations.
 

Transportation services are classified under the HSN/SAC system, specifically within the primary heading 9965. The precise 6-digit code is determined by the mode of transport utilised. Below are the primary SAC codes for various transportation services as of 2026:

Primary SAC codes for transport services (2025-26)

Key takeaway: For the majority of goods transport via road, rail, air, or water, the primary codes are 996511, 996512, 996531, or 996521, respectively. The applicable GST rate is largely determined by whether the transporter elects to claim Input Tax Credit (ITC).

A unique feature of GST on transportation services in India is that the applicable tax rate is determined by the transporter’s decision regarding Input Tax Credit (ITC). The two primary frameworks for the 2025-26 financial year are:

GST rate options for transporters

• Option 1: Concessional rate (without ITC): Transporters may elect to pay GST at a reduced rate of 5%. However, under this provision, they are prohibited from claiming ITC on business overheads, such as fuel, vehicle spares, tyres, or maintenance services.
• Option 2: Standard rate (with ITC): Alternatively, transporters can opt for a 12% GST rate. This selection allows the business to claim full Input Tax Credit on all GST-compliant business expenses, including the purchase of new commercial vehicles and high-value maintenance.

Strategic selection: which framework suits your business?

• Small fleet operators: Businesses with lower overheads or those who primarily procure non-GST-compliant inputs may find the 5% (without ITC) model simpler and more cost-effective for their cash flow.
• Large-scale logistics firms: Operators managing extensive fleets with significant ITC-eligible capital expenditure (such as new truck fleets or automated warehousing) typically prefer the 12% (With ITC) model. This often results in a lower effective tax burden by offsetting outward liability against input taxes paid.

Crucial requirement: This election must be made at the commencement of the financial year and applied consistently across all services. While the SAC code remains unchanged, the applied tax rate serves as the primary differentiator.

The precise application of the SAC code (Services Accounting Code) for transportation is far more than a mere administrative detail; it carries significant financial and legal implications. Ensuring accuracy in your invoicing is critical for the following reasons:

• Accurate GST liability: The SAC code directly dictates the applicable GST rate. An error here could lead to the incorrect calculation of tax, resulting in either the short-payment of dues or unnecessary over-payment.
• Mitigating penalties and scrutiny: Mismatched or erroneous codes on tax invoices and GSTR-1 returns are frequent triggers for GST department audits and penalty notices. Inaccurate classification can be viewed as a compliance failure by the authorities.
• Ensuring ITC for your clients: Your customers rely on the correct SAC code appearing on your invoices to claim their Input Tax Credit (ITC). A clerical error on your part could block their credit, leading to strained business relationships and potential payment delays.
• Eligibility for concessional schemes: Transporters opting for specific GST frameworks, such as the composition scheme or the 5% (No ITC) model, must utilise the correct codes to remain eligible and correctly classified.
• Precise financial reporting: Accurate classification facilitates a clearer analysis of your revenue streams and operational overheads, aiding in more robust financial planning and informed business decisions.
