Harmonized System of Nomenclature, aka HSN code, is an international product classification system. While it was initially proposed by the World Customs Organization (WCO), it is essential for seamless GST compliance as it serves as the classification for goods. With the help of HSN code, business owners can streamline tax processes through categorizing goods, facilitating efficient tax calculation, and documentation. One of the biggest advantages of the HSN code is its ability to deliver accurate determination of GST rates, simplify the process of GST return filing, and further reduce error risks. Moreover, HSN code makes inventory management much simpler and hassle-free than ever before, along with supply chain operations, which aid in improving the overall efficiency of business operations. Let’s look at the HSN codes under GST.
- Taxpayers with a turnover of 5 CR INR and above shall use a 4-digit HSN code.
- Taxpayers with a turnover between 1.5 CR to 5 CR shall use a 2-digit HSN code.
- Taxpayers with a turnover below 1.5 CR do not require any HSN code.
- Taxpayers can also view the draft list of HSN codes in the public domain through the government GST websites.
- Under the GST law, the services will be classified as per the service accounting code (SAC)
Any topic related to goods and services tax (GST) would be incomplete without mentioning the SAC code. Originally based on the concept of the United Nations Central Product Classification, this code has been modified in India by CBIC. SAC code focuses primarily on the Indian Taxation Framework. However, if a service or product is not listed in the SAC code, it automatically defaults to 18% GST tax. Let’s understand how the SAC code plays a vital role for businesses.
- Distinctive Classification
The SAC code allocates a unique code to different services, which provides a more accurate classification.
- GST Rate Identification
Here, the code assists GST taxpayers in identifying applicable GST rates for their services.
- Compliance Requirement
It is mandatory for GST taxpayers to mention SAC codes, invoices, and returns while registering on the GST portal. It ensures compliance with tax regulations.
- GST collection analysis
One of the major benefits of having a SAC code is that it enables the government to analyze GST collection efficiently for each service category. This helps towards a more effective tax administration and revenue management.
Now that we have covered the basics of these 2 codes and how they differ from each other. Let’s understand how these 2 codes differ from each other through a table.
