# How to Update GST Rates in Bulk as per New Slabs? (Effective 22 September 2025)

With the GST reform effective from **22 September 2025**, India’s GST structure has been simplified from four main slabs (5%, 12%, 18%, 28%) to just **two primary slabs: 5% and 18%**, plus a special **40% slab for luxury and sin goods**. This change aims to make compliance easier for businesses and reduce confusion for consumers 

**Refrens** provides a straightforward way to update your inventory and stay compliant with these new GST rates.

#### Step 1: Check the New GST Slabs for Your Items

**Review the official GST rate list** to determine the correct slab for each item you sell. The government has published a detailed list of which goods and services fall under each new slab.

#### Step 2: Export All Items from Refrens

Navigate to your **Inventory Dashboard** and click **"Download CSV"** to get a CSV file of all your inventory items.

**3.2) Change the column names:**

To ensure that the CSV filw is ready for bulk updation, we need to change the column names to system accepted formats:

For that, change -

**item Type **to **itemType**
**Tax Rate** to **gstRate**
**Manage Stock** to** isStockManaged**
**SKU **to **sku**

As shown below:

**3.3) Replace the old GST Rates**

Then, for each item, **replace the old GST rate** (5%, 12%, 18%, 28%) with the new applicable rate (5%, 18%, or 40% for luxury/sin goods).


#### Step 4: Upload the Updated CSV

Go back to **Inventory Dashboard > "Add Items" Dropdown Options > "Bulk Update Inventory":**

#### Step 5: Verify and Refresh

The update process may take a few seconds to a minute, depending on the number of items.** **Refresh the page after a few seconds to check if the new rates have been updated.
