History of Service Accounting Codes (SAC)
The United Nations Statistical Division (i.e.; UNSD) developed the UN Central Product Classification (i.e.; UN-CPC), and based on this, the Central Board of Indirect Taxes and Customs (i.e., CBIC) developed the SAC codes with some modification in the Indian context.
SAC codes were first introduced in 1994 under the service tax regime.
As of now, the UN-CPC covers almost all service categories, and all 193 UN countries use it. Under the SAC system developed by UNSD, each service carries a six-digit code shown in the table below.
| SAC Structure provided by UNSD via UNCPC | |
| Digits | Reference |
| First 2 digits | Represent – Chapter (i.e.; broad category of services) |
| Next 2 digits | Represent – Headings (i.e.; sub category of services) |
| Last 2 digits | Represents -Sub Headings (i.e.; specific service) |
Entry of SAC in India under GST System
India adopted the same SAC system as of service tax regime under Goods and service Tax (GST) on 01 July 2017.
Chapter 99 of the GST Services Tariff governs the SAC codes. It does not form part of the Customs Tariff Act, 1975, and the GST system has specifically developed it for service classification. All the SAC codes are start from 99.
Let’s understand with an example:
The 6 -digit SAC code of— Transport services is 996511.
Let’s bifurcate the SAC code 996511 by applying the rule as explained above:
| SAC Structure -99-65-11 | |
| Digits | Reference |
| First 2 digits— “99” | Represent – Chapter 99 of “GST Services Tariff” |
| Next 2 digits— “65” | Represent – Headings (i.e.; sub category of service —”Transport service”) |
| Last 2 digits—”11” | Represent -Sub Headings (i.e.; specific service —Trasport service by road) |
