Are you running a business in Kerala and selling products or services to customers in other states? Then you should understand the difference between Inter-State and Intra-State GST.

These two terms decide whether you should charge CGST and SGST or IGST on your sales invoices. Choosing the wrong tax type can lead to incorrect invoices, GST return errors and unnecessary compliance problems.

Whether you run a small shop in Malappuram, a digital marketing agency in Kochi, a software startup in Trivandrum, or a consulting business in Kozhikode, understanding GST rules is important when your business grows beyond Kerala.

In this guide, we explain the difference between Inter-State and Intra-State supplies in simple English. You will also learn about the Place of Supply rules, tax calculation examples, GST registration requirements and how a virtual office from KANs HUB in Wandoor, Malappuram can support your business address requirements.

1. What Is Intra-State GST?

An Intra-State supply generally happens when the location of the supplier and the Place of Supply are in the same state.

For example, imagine that your business is registered in Kerala and you sell a product to a customer in Kerala. If the Place of Supply is also Kerala, the transaction is generally treated as an Intra-State supply.

In this situation, GST is divided into two parts:

• CGST: Central Goods and Services Tax, collected by the Central Government.
• SGST: State Goods and Services Tax, collected by the Kerala Government.

Remember that the applicable GST rate depends on the goods or services being supplied. The example of 18% GST used below is only for illustration. Not every product or service attracts 18% GST.

2. What Is Inter-State GST?

An Inter-State supply generally happens when the supplier's location and the Place of Supply are in two different states.

For example, suppose your business is registered in Malappuram, Kerala, and you provide a service to a business customer in Bengaluru, Karnataka. If the Place of Supply is Karnataka, the transaction is generally treated as an Inter-State supply.

In such cases, IGST (Integrated Goods and Services Tax) is generally charged instead of CGST and SGST separately.

Inter-State transactions are common for online businesses, software companies, digital marketing agencies, consultants, wholesalers and service providers working with customers across India.

3. Difference Between Intra-State and Inter-State GST

The following table explains the main differences in a simple way.

Important: The Place of Supply rules must be checked before deciding the tax type. The customer's location alone may not decide the tax treatment in every transaction.

---

4. How Does GST Decide the Place of Supply?

Place of Supply is one of the most important concepts in GST. It helps determine whether a transaction is Intra-State or Inter-State.

For goods, the Place of Supply is generally connected to where the movement of goods ends for delivery. If goods are not moved, other rules may apply.

For services, the general rule is different. In many cases, when a service is supplied to a registered business, the Place of Supply is the location of that registered recipient. For an unregistered recipient, the address available in the supplier's records may be relevant.

However, some services have special Place of Supply rules. Examples include services connected with immovable property, accommodation, events, transportation and certain other services.

For this reason, businesses should not decide the tax type only by looking at the billing address. The nature of the supply and the relevant Place of Supply provision must also be considered.

5. GST Calculation Examples for Kerala Businesses

Example 1: Intra-State Service Sale

A digital marketing agency registered in Wandoor, Malappuram provides marketing services to a registered client in Kochi, Kerala. Assume that the Place of Supply is Kerala and the applicable GST rate is 18%.

Since the supplier location and Place of Supply are both in Kerala in this example, CGST and SGST apply.

Example 2: Inter-State Service Sale

Now assume the same agency provides the same service to a registered client in Bengaluru, Karnataka. Assume the Place of Supply is Karnataka and the applicable GST rate is 18%.

In this example, IGST applies because the supplier location and Place of Supply are in different states.

Note: These examples use an assumed GST rate of 18%. Always confirm the correct rate and Place of Supply for your actual goods or services before issuing an invoice.

6. GST Registration Rules for Inter-State Sales

One common misunderstanding among new business owners is that every Inter-State sale automatically requires GST registration from the first rupee of turnover. The actual rules are more detailed.

A. Inter-State Supply of Goods

Under Section 24 of the CGST Act, persons making taxable inter-state supplies are generally required to register for GST, subject to applicable exemptions and notifications.

Therefore, a business selling taxable physical goods from Kerala to customers in another state should check the registration requirement before starting those supplies. Do not assume that the normal turnover threshold will always protect an inter-state goods seller.

B. Inter-State Supply of Services

Service providers have an important exemption to understand.

Under Notification No. 10/2017 – Integrated Tax, persons making inter-state taxable supplies of services with aggregate turnover not exceeding ₹20 lakh in a financial year are generally exempt from obtaining GST registration, subject to the conditions and other applicable provisions.

This means a small Kerala-based consultant, designer, software developer or digital marketing service provider may be able to serve clients in other states without GST registration while eligible for this exemption.

However, once the applicable threshold is crossed, or another compulsory registration provision applies, registration may become necessary. Special category state thresholds and other statutory conditions should also be checked where relevant.

C. E-Commerce and Other Special Cases

Businesses selling through e-commerce platforms should check the specific GST provisions applicable to their products, services and platform arrangements. There are different rules for goods, services, e-commerce operators and certain eligible small suppliers.

Do not assume that every online seller has the same registration requirement. The nature of the supply, turnover, interstate activity and applicable notifications all matter.

7. Why Inter-State GST Knowledge Matters for Startups and Growing Businesses

Today, a business does not need to operate from a large office to serve customers across India. A small startup in Malappuram can provide services to companies in Kochi, Bengaluru, Chennai, Mumbai, Delhi and other locations.

For example, a business operating from Kerala may provide:

• Digital marketing and social media management.
• Website development and software services.
• Online education and training.
• Business consulting and professional services.
• Graphic design, video editing and creative services.
• Recruitment and HR support.
• Online sales and product distribution.

As your customer base grows, you may have to issue both Intra-State and Inter-State invoices. Understanding GST helps you select the correct tax type, maintain proper records and avoid common billing mistakes.

It is also useful when you plan to change your business structure from a proprietorship to a partnership or private limited company. Company registration, GST registration and bank account applications involve different requirements. Your business address and supporting documents should match the actual legal structure and application details.

8. Why Your Business Address Matters for GST Registration

When applying for GST registration, businesses must provide details of their Principal Place of Business and submit the documents required for that address.

Depending on the arrangement, address documents may include:

• Rental Agreement or other valid occupancy document.
• Owner's NOC (No Objection Certificate), where applicable.
• Property tax receipt or other property-related documents.
• Electricity bill or other accepted utility document.

The exact documents depend on the premises, the nature of the occupancy and the requirements of the GST application. A virtual office address should only be used when the arrangement and supporting documents meet the applicable legal requirements.

A virtual office does not automatically make every business eligible for GST registration. The applicant must provide correct information about the actual business activities, places of business and any additional locations where required.

9. How KANs HUB Virtual Office Supports Kerala Businesses

KANs HUB provides a virtual office service from Wandoor, Malappuram, Kerala, starting at ₹5,999/year.

The service is designed for businesses that need an address and applicable supporting documents for business purposes, subject to the requirements of the relevant authority or institution.

About 100% Owned Property (Zero Lease Risks): This phrase describes the property arrangement: the commercial building is owned by its property owner, and the KANs HUB virtual office arrangement does not depend on a third-party master lease. It does not mean that KANs HUB owns the building or that every legal, verification or approval risk is zero.

10. Pan-Kerala Reach from Wandoor

Your business does not have to be physically located in a major city to work with customers across India. If you need a suitable business address in Kerala, you can explore the KANs HUB virtual office service from Wandoor, Malappuram.

Whether you are starting a proprietorship, partnership firm or private limited company, it is important to check the address requirements for your particular registration. A Kerala virtual office address should not be treated as an address for GST registration in another state.
