SAC Code (Service Accounting Code)

Definition

SAC Code, or Service Accounting Code, is a standardized classification system adopted under India's Goods and Services Tax (GST) regime to uniquely identify and categorize various types of services. Similar to how HSN (Harmonized System of Nomenclature) codes classify goods, SAC codes classify services into specific categories to determine the applicable GST rate. SAC codes are typically 6-digit numbers, with the first two digits being "99" (indicating a service), followed by a 2-digit chapter heading and a 2-digit sub-category that narrows down the specific service type.

The SAC code system is derived from the United Nations Central Product Classification (UNCPC) and has been adapted for the Indian GST framework. Each SAC code maps to a specific GST rate, which can be 5%, 12%, 18%, or 28% depending on the nature of the service. For example, SAC code 998311 covers management consulting services (18% GST), SAC code 997211 covers freight transport by road (5% GST under specific conditions), and SAC code 998313 covers information technology consulting services (18% GST). Businesses must quote the correct SAC code on all tax invoices to ensure proper classification and avoid disputes with tax authorities.

For businesses providing services, accurately identifying and applying the correct SAC code is crucial for compliance. An incorrect SAC code can lead to wrong GST rate application, resulting in short payment of tax (attracting interest and penalties) or overpayment (leading to cash flow issues). SAC codes are mandatory on e-invoices and are used by the GST system for automated reconciliation and audit trails. Platforms like OneFinOps maintain an updated SAC code database and automatically suggest the appropriate code during invoice creation, helping businesses maintain accuracy in their GST compliance.

Key Points

• SAC codes are 6-digit numbers starting with "99" that classify services under GST, analogous to how HSN codes classify goods, and are mandatory on all service invoices.
• Each SAC code is mapped to a specific GST rate (5%, 12%, 18%, or 28%), and using the wrong code can result in incorrect tax computation and potential compliance issues.
• Businesses with annual turnover above Rs. 5 crore must mandatorily mention the 6-digit SAC code on invoices; those below this threshold may use 4-digit codes.
• SAC codes are essential for e-invoicing compliance as the Invoice Registration Portal (IRP) validates the code against the declared tax rate during IRN generation.
• The GST Council periodically updates SAC codes and their corresponding tax rates, making it important for businesses to stay current with the latest notifications.
