Claiming GST refunds is very vital and time-consuming for Indian businesses in general and exporters, in particular, and the businesses that experience inverted duty structures. The traditional process envisages complicated forms, compliance nightmares, and long delays. That is why the GST refund calculator tool can be a game-changer.

In this blog, we are going to take you through how the tool works, provide a step-by-step demonstration, and highlight the advantages of why and how you should use it. It's time to stop guessing and start claiming with surety.

What is a GST refund?

A GST Refund Calculator is a useful tool that helps businesses and individuals estimate the refund amount they are eligible to claim under GST (Goods and Services Tax). In such cases, the excess amount becomes eligible for a refund, and a situation arises.

Who Can Claim a GST Refund?

● Exporters of goods and services
● Businesses with an inverted duty structure (higher input tax than output tax)
● Sellers selling on E-commerce platforms.
SEZ units and developers
● Taxpayers who have paid excess GST inadvertently
Additionally, taxpayers who have inadvertently paid excess GST can apply to get that amount refunded through the appropriate process under GST law.

What Is the GST Refund Calculator?

The GST refund calculator is a tool made specifically to facilitate the process of calculating GST refunds on zero-rated outputs, especially for exporters and start-ups. All you need to do is enter your export turnover and valid ITC, and the calculator will automatically give your calculation as an export refund under Rule 89(4) of the CGST Rules. There are no manual formulas, no mistakes, simply correct compliant estimates on your zero-rated supplies.

The MYGST Refund Calculator helps you estimate the total GST refund amount you’re eligible to claim. It streamlines the process by allowing secure data entry and generates a detailed refund report within minutes.

Use Case:
To calculate the refund of input tax credit (ITC) on goods/services exported without paying IGST (under LUT) or the refund of IGST paid on export.

Example:
An exporter exporting goods worth ₹10,00,000 can calculate how much GST paid on inputs is eligible for a refund.

2. Inverted Duty Structure
Use Case:
When the tax rate on inputs is higher than the output, businesses can use the calculator to estimate how much refund they're eligible for.

Example:
If you buy raw material at 18% GST and sell the finished product at 5%, you can claim the difference.
