How To Create an IGST Invoice Format

If you run a business that involves interstate transactions in India, understanding how to create an IGST invoice is very important. IGST stands for Integrated Goods and Services Tax, and it applies when goods or services are sold between different states. In this blog, we will explain everything you need to know about creating an IGST invoice format using simple words.

We’ll go through each part of the invoice and guide you on how to fill it out correctly, step by step.

What is IGST?

IGST (Integrated Goods and Services Tax) is one of the main types of taxes under India’s GST system. It is applied when goods or services are sold from one state to another. For example, if a company in Maharashtra sells goods to a company in Tamil Nadu, IGST will be charged on that sale.

IGST is important because it helps manage how tax money is shared between the central government and the state where the sale happens. Unlike CGST (Central Goods and Services Tax) and SGST (State Goods and Services Tax), which are used for sales within a single state, IGST is only used for interstate sales.

Why is an IGST Invoice Important?

Creating an IGST invoice is a legal requirement for any business involved in interstate transactions. A proper IGST invoice helps you:

• Record sales accurately.
• Calculate taxes correctly.
• Comply with GST regulations.
• Avoid penalties and legal issues.

A well-organized invoice also helps maintain good business relationships with your clients and ensures smooth tax filing. If you don’t create the right invoice, it may cause problems with tax authorities and hurt your business reputation.

Key Parts of an IGST Invoice Format

Now, let’s go over the main sections that must be included in an IGST invoice format. Each part serves a specific purpose and must be filled out carefully.

1. Invoice Title and Number

At the top of the invoice, you need to clearly mention the words “Tax Invoice.” You should also assign a unique invoice number. The invoice number must follow a sequence and should not be repeated. Along with this, add the date when the invoice is issued.

2. Seller’s Information

This section includes details about the seller (your business). You need to provide:

• Business name.
• Registered address.
• GSTIN (Goods and Services Tax Identification Number).

Your GSTIN is a unique number that identifies your business under the GST system. Make sure it’s correct because this is an important detail.

3. Buyer’s Information

Next, you’ll need to add the buyer’s details. This includes:

• Buyer’s name.
• Buyer’s address.
• Buyer’s GSTIN (if they are registered under GST).

Just like the seller’s GSTIN, the buyer’s GSTIN should also be accurate.

4. Description of Goods or Services

In this section, describe what you are selling. This could be products or services. Include:

• Name or description of the goods/services.
• Quantity.
• Unit price.
• Total value (before tax).

This section allows both parties (you and your customer) to clearly understand what is being sold and how much it costs.

5. HSN or SAC Code

Every product or service under the GST system has a unique code. These codes help the tax authorities identify the type of goods or services being sold.

• HSN Code is used for goods.
• SAC Code is used for services.

Make sure to include the correct HSN or SAC code for what you are selling.

6. Taxable Value

This is the total amount of the sale, excluding taxes. It is calculated by multiplying the quantity by the unit price. For example, if you are selling 100 units of a product that costs ₹50 per unit, the taxable value will be ₹50 x 100 = ₹5000.

7. IGST Rate and Amount

This is one of the most important parts of the IGST invoice format. Here, you need to mention the IGST rate that applies to your product or service. The IGST rate is different for different types of products or services, so make sure you apply the correct rate.

Once you know the IGST rate, you can calculate the IGST amount by multiplying the taxable value by the IGST rate.

For example:

• If the taxable value is ₹10,000 and the IGST rate is 18%, the IGST amount will be: ₹10,000 x 18% = ₹1,800.

8. Total Invoice Value

The total invoice value is the sum of the taxable value and the IGST amount. This is the total amount that the buyer needs to pay. Make sure to mention this amount clearly in both numbers and words.

For example:

• Total Invoice Value: ₹11,800 (Rupees Eleven Thousand Eight Hundred Only).

9. Payment Terms (Optional)

If you have any specific payment terms, you can mention them here. This may include:

• The due date for payment.
• Accepted payment methods (e.g., bank transfer, cheque, etc.).
• Any penalties for late payment or discounts for early payment.

10. Declaration

In this section, you can add a standard declaration. This is a statement that confirms the details of the invoice are correct. For example, you can write:

“I declare that the information given in this invoice is accurate and true to the best of my knowledge.”

11. Authorized Signature

Finally, the invoice should be signed by an authorized person from your business. This could be the owner, director, or any person authorized to issue invoices. A signature is a must to make the invoice official.

How To Create an IGST Invoice – Step by Step

Creating an IGST invoice format may seem complicated, but if you follow a simple process, it becomes easy. Here’s a step-by-step guide:

Step 1: Choose an Invoice Template

Start by choosing an invoice template. You can find many free templates online, or you can use accounting software like MargBooks to create a professional invoice. Make sure the template includes all the important sections we discussed earlier.

Step 2: Fill in Seller and Buyer Information

Enter the details of the seller (your business) and the buyer. Double-check the GSTINs of both parties to avoid any mistakes. If the buyer is not registered under GST, you can skip the GSTIN for the buyer.

Step 3: Add the Description of Goods or Services

List the items being sold, along with their quantity, unit price, and total value. Make sure to add the HSN or SAC code for each item. This helps ensure compliance with GST regulations.

Step 4: Apply the Correct IGST Rate

Check the IGST rate that applies to your goods or services. Once you know the rate, calculate the IGST amount by applying the rate to the taxable value. Include this information in a separate section of the invoice.

Step 5: Calculate the Total Invoice Value

Finally, calculate the total invoice value by adding the taxable value and the IGST amount. Mention this total clearly on the invoice.

Step 6: Review and Sign the Invoice

Before sending the invoice to the buyer, review all the details to make sure they are correct. Once everything is in order, sign the invoice or add a digital signature if you are sending it electronically.

Best Practices for Creating IGST Invoices

To ensure that your IGST invoices are always accurate and compliant, here are some best practices to follow:

• Use Software: Using accounting software like MargBooks can make the process of creating invoices faster and easier. It also helps avoid errors when calculating taxes.
• Verify GSTINs: Always double-check the GSTINs of both the seller and the buyer before issuing the invoice. Incorrect GSTINs can cause problems during tax filing.
• Issue Timely Invoices: Ensure that invoices are issued promptly after the sale or service. Delays can complicate tax filings and cause penalties.
• Keep Records: Maintain proper records of all invoices for future reference or audits. This can help in case of any discrepancies or tax reviews.
