HSN & SAC Code Complete Guide – Choosing the Correct Code for GST

Navigating GST compliance can feel like a maze, and at the heart of it are HSN and SAC codes. Choosing the wrong code can lead to incorrect tax filings, payment discrepancies, and unwelcome penalties from the tax authorities. This comprehensive HSN code guide is designed to demystify this critical aspect of GST for Indian businesses. HSN (Harmonized System of Nomenclature) for goods and SAC (Services Accounting Code) for services form a universal classification system that determines how your products and services are taxed. Understanding these codes is not just a regulatory formality; it’s a non-negotiable requirement for accurate invoicing, seamless GST filing, and overall business health. This article serves as your complete guide to HSN and SAC India, simplifying the process and empowering you to handle your GST obligations with confidence.

Understanding HSN and SAC Codes: The Foundation of GST Classification

Before you can apply the correct GST rate or file your returns, you must first master the language of product and service classification under the GST regime. HSN and SAC codes provide a standardized framework that ensures uniformity and prevents ambiguity in trade, both domestically and internationally. Think of them as the universal product and service codes that the entire tax system understands. Getting a firm grasp of their structure and purpose is the first and most important step towards flawless GST compliance.

What is an HSN Code? A Global Standard for Goods

HSN stands for Harmonized System of Nomenclature. It is a globally recognized system developed by the World Customs Organization (WCO) to classify goods in a logical and systematic manner. Originally created for customs purposes to streamline international trade, India has adopted this system for GST classification. This helps in creating a uniform tax structure across the country. For anyone dealing in goods, understanding HSN codes in India is fundamental.

The HSN code is typically an 8-digit number, where each pair of digits represents a deeper level of classification:

Chapter (First 2 digits): This represents the broad category of the product. For instance, Chapter 09 covers coffee, tea, maté, and spices.
Heading (Next 2 digits): This narrows down the category. Within Chapter 09, Heading 0901 refers specifically to coffee.
Sub-heading (Next 2 digits): This provides more specific details about the product. For coffee under Heading 0901, Sub-heading 090121 refers to “caffeinated coffee, not roasted.”
Tariff Item (Final 2 digits): These last two digits provide further, more granular classification, often specific to the country’s requirements for import/export tariffs.

What is a SAC Code? Classifying Services in India

While HSN codes are for goods, SAC codes are used to classify services. SAC stands for Services Accounting Code, a classification system developed by India’s Central Board of Indirect Taxes and Customs (CBIC) specifically for identifying and taxing services under GST. This system ensures that every conceivable service has a unique code, making it easy to determine the applicable tax rate and report it correctly.

The structure of a SAC code is simpler than an HSN code. It is always a 6-digit number, and the first two digits are consistently ’99’. This ’99’ prefix immediately identifies the code as pertaining to a service. The remaining four digits categorize the specific nature of the service. For example, the SAC for general legal advisory services is 998213. Providing accurate SAC code information India on your invoices is just as crucial as providing the correct HSN code.

Why Getting These Codes Right is Crucial for Your Business

Treating HSN and SAC codes as a mere formality is a significant business risk. These codes are directly linked to the core of your financial and tax operations, and errors can have cascading negative effects. Here’s why precision is paramount:

Accurate Tax Rates: The primary function of an HSN or SAC code is to determine the GST rate applicable to your goods or services. A wrong code can lead to you charging the wrong tax rate—either overcharging your customer or underpaying the government, both of which create serious problems.
Correct Invoicing: As per GST rules, mentioning the correct HSN/SAC code on your tax invoices is mandatory, depending on your annual turnover. Failure to do so can render your invoices invalid and may cause issues for your B2B customers claiming Input Tax Credit (ITC).
Simplified GST Returns: Your GST returns, especially GSTR-1, require a summary of your sales categorized by HSN/SAC codes. Using the correct codes from the start makes filing your returns faster, more accurate, and less prone to errors that could trigger scrutiny.
Avoiding Penalties: The GST authorities can levy significant penalties for incorrect code usage, especially if it leads to tax evasion. This can result in notices, demands for the tax shortfall along with interest, and additional penalties for non-compliance.

Your Step-by-Step HSN Code Guide for Finding the Right Code

Finding the right code might seem daunting with thousands of options available, but the government has provided clear guidelines and tools to simplify the process. This HSN code guide will walk you through the exact requirements and steps you need to follow, ensuring you select the correct code every time. The key is to understand your turnover bracket and use the official resources provided on the GST portal.

HSN Code Requirement: Does Your Turnover Matter?

Yes, your Aggregate Annual Turnover (AATO) plays a decisive role in determining the level of HSN code detail you need to report on your invoices and in your returns. The government has defined specific thresholds to ease the compliance burden on smaller businesses.

Aggregate Annual Turnover (AATO)	HSN Code Requirement	Applicable Supplies
Up to ₹5 Crore	4-digit HSN code is mandatory.	B2B (Business-to-Business) Supplies
Up to ₹5 Crore	Optional (but recommended for clarity)	B2C (Business-to-Consumer) Supplies
Above ₹5 Crore	6-digit HSN code is mandatory.	All Supplies (B2B & B2C)
Imports / Exports	8-digit HSN code is mandatory, regardless of turnover.	All Import/Export Transactions

Understanding this table is crucial. If your turnover exceeds ₹5 crore, you must be meticulous in using a 6-digit code for every single invoice you issue, whether to a business or a direct consumer.

How to Find the Correct HSN Code for Your Products

The process of choosing HSN code for GST should be systematic. Guesswork can be costly. Follow these simple steps using the official government tool to ensure accuracy.

Step 1: Navigate to the official GST Portal and access the HSN search tool. You can find it under Services > User Services > Search HSN Code. Here is the direct link: GST Portal HSN/SAC Search.
Step 2: Once on the page, you have the option to search by “Description.” Type a clear and common name for your product in the search bar. For example, if you sell leather footwear, start by searching for “leather shoes” or “footwear.”
Step 3: The portal will display a list of relevant Chapters and Headings. Analyze these results carefully. For “footwear,” you will likely see results related to Chapter 64, which covers “Footwear, gaiters and the like; parts of such articles.”
Step 4: Click on the most relevant Chapter/Heading to drill down further. You will see a more detailed list of sub-headings. Read the descriptions carefully to find the one that most precisely describes your product. For instance, you might find a specific sub-heading for men’s leather shoes versus sports shoes.
Pro Tip: If you are a reseller, check the invoices you receive from your supplier or manufacturer. They are typically required to mention the correct HSN code, which you can adopt for your own sales of that product.

How to Select SAC Codes for Your Services with Confidence

The process for finding the correct service code is very similar and equally straightforward. Following a structured approach is the best way how to select SAC codes India.

Step 1: Use the same GST Portal HSN/SAC Search tool.
Step 2: Select the “Search SAC” option. In the search bar, describe the service you provide. For example, use terms like “accounting services,” “web design services,” or “renting of immovable property.”
Step 3: The portal will return a list of matching 6-digit SAC codes along with their descriptions. Review the descriptions to find the one that accurately reflects the nature of your service. For accounting, you might find SAC 998222 for “Accounting and bookkeeping services.” Select the code that is the most specific match.

Best Practices for HSN and SAC Code Compliance

Simply finding the right code is only half the battle. Consistent and accurate implementation is key to long-term compliance and avoiding trouble. Adopting a few simple organizational habits can save you significant time and prevent costly errors down the line. Here are some of the best practices for HSN and SAC codes India that every business should implement.

Maintain a Master List

For any business dealing with multiple products or services, maintaining a master list is non-negotiable. Create a simple spreadsheet that details:

Product/Service Name
Detailed Description
Corresponding HSN/SAC Code
Applicable GST Rate (%)

This master list becomes your single source of truth for invoicing, accounting, and GST return filing. It ensures consistency across your entire team and reduces the risk of someone using an old or incorrect code by mistake. Regularly review and update this list, especially when you introduce new products or when the government announces changes to GST rates or classifications.

What to Do if You Use the Wrong Code?

Mistakes can happen. The important thing is to identify them early and take corrective action swiftly. Using a wrong HSN/SAC code can lead to an incorrect tax payment (either excess or short). This can trigger a GST notice from the department and result in a liability for the tax shortfall plus interest.

If you discover you’ve used an incorrect code and charged the wrong tax rate, you must issue a debit note (if you undercharged tax) or a credit note (if you overcharged tax) to the customer. This financial instrument officially corrects the original invoice. You must then report these debit/credit notes accurately in your GSTR-1 for the month in which they were issued. This rectifies your tax liability. If the process seems complex, it is highly advisable to consult a tax professional. At TaxRobo, our experts can guide you through the rectification process to ensure it is handled correctly.

Common Mistakes to Avoid

Staying compliant often means knowing what not to do. Here are some common pitfalls businesses fall into:

Using a Generic Code: Avoid using a general or “miscellaneous” category code if a more specific code for your product or service exists. The rules require you to use the most specific code applicable.
Not Staying Updated: The GST Council periodically reviews and revises HSN/SAC codes and their corresponding tax rates. It is your responsibility to stay informed of these changes and update your master list and billing systems accordingly.
Guessing the Code: Never guess a code because it “seems right.” Always use the official GST portal’s search tool or consult a tax expert to verify the correct code. A guess can easily lead to non-compliance.

Frequently Asked Questions (FAQ) Section

1. What is the penalty for using the wrong HSN code in India?

An incorrect HSN code can lead to a penalty under Section 125 of the CGST Act, which can be up to ₹25,000 for a “general penalty” where no other specific penalty is prescribed. More importantly, if the incorrect code results in an underpayment of tax, you will be liable for the entire tax shortfall plus interest from the original due date, which can be a much larger financial burden.

2. Do I need to mention the HSN code for GST-exempted goods?

Yes, it is a best practice and often required for proper reporting. Even though no tax is levied on exempted goods, you are still required to report these sales in your GSTR-1 returns. Mentioning the correct HSN code allows for accurate classification, transparent record-keeping, and a complete summary of your business activities as required by the GSTN portal.

3. How many digits of the HSN code do I need to use for my small business?

It depends entirely on your aggregate annual turnover (AATO). If your AATO is up to ₹5 crore, you are only required to use a 4-digit HSN code for your B2B (business-to-business) invoices. If your AATO exceeds ₹5 crore, you must use a more detailed 6-digit HSN code for all your supplies, both B2B and B2C.

4. Where can I find the most reliable list of HSN and SAC codes?

The most reliable and authoritative source for HSN and SAC codes is always an official government portal. You should primarily use the HSN/SAC search functionality available on the official GST Portal. For a comprehensive list of rates tied to codes, you can also refer to the CBIC GST Rates page. Avoid relying on unverified third-party websites or blogs for final decisions, as they may contain outdated or inaccurate information.
