+# Sending GST Reminders
+
+You can send email reminders to your Customers and Suppliers so that they can directly add or update their GSTIN numbers
+
+To send GSTIN Reminders, you can either open the Customer / Supplier record or **GST Settings**
+
+<img class="screenshot" alt="GST Settings" src="{{docs_base_url}}/assets/img/regional/india/gstin-settings.png">
+
+Here you can click on the "Send GSTIN Update Reminders" button to send email reminders to all your customers
+
+### Updating GSTIN
+
+Your customers will receive an email asking them to update their GSTIN and that email will link them to a portal page:
+
+<img class="screenshot" alt="GST Portal Page" src="{{docs_base_url}}/assets/img/regional/india/gstin-portal-update.png">
+
+Here they can update their GSTIN and it will automatically be added to your customer GSTIN record.

+# GST Features in ERPNext
+
+### 1. Setting up GSTIN
+
+GST Law requires that you maintain the GSTIN number for all your suppliers and vendors. In ERPNext, GSTIN is linked to the **Address**
+
+<img class="screenshot" alt="GST in Customer" src="{{docs_base_url}}/assets/img/regional/india/gstin-customer.gif">
+
+**GST for your Company Address**
+
+You also need to set the Address for your own Company and your Company's GST Number
+
+Go to the Company master and add the GSTIN to your default address.
+
+<img class="screenshot" alt="GST in Company" src="{{docs_base_url}}/assets/img/regional/india/gstin-company.gif">
+
+### 2. Setting up HSN Codes
+
+According to the GST Law, your itemised invoices must contain the HSN Code related to that Item. ERPNext comes pre-installed with all 12,000+ HSN Codes so that you can easily select the relevant HSN Code in your Item
+
+<img class="screenshot" alt="HSN in Item" src="{{docs_base_url}}/assets/img/regional/india/hsn-item.gif">
+
+### 3. Making Tax Masters
+
+To setup Billing in GST, you need to create 3 Tax Accounts for the various GST reporting heads CGST - Central GST, SGST - State GST, IGST - Inter-state GST
+
+Go to your **Chart of Accounts**, under the Duties and Taxes head of your account, create 3 Accounts
+
+**Note:** Usually the rate in CGST and SGST is half of IGST. For example if most of your items are billed at 18%, then create IGST at 18%, CGST and SGST at 9% each.
+
+<img class="screenshot" alt="GST in Customer" src="{{docs_base_url}}/assets/img/regional/india/gst-in-coa.png">
+
+### 4. Make Tax Templates
+
+You will have have to make two tax templates for both your sales and purchase, one for in state sales and other for out of state sales.
+
+In your **In State GST** template, select 2 accounts, SGST and CGST
+
+<img class="screenshot" alt="GST in Customer" src="{{docs_base_url}}/assets/img/regional/india/gst-template-in-state.png">
+
+In your **Out of State GST** template, select IGST
+
+### 5. Making GST Ready Invoices
+
+If you have setup the GSTIN of your Customers and Suppliers, and your tax template, you are ready to go for making GST Ready Invoices!
+
+For **Sales Invoice**,
+
+1. Select the correct Customer and Item and the address where the transaction will happen.
+2. Check if the GSTIN of your Company and Supplier have been correctly set.
+3. Check if the HSN Number has been set in the Item
+4. Select the the **In State GST** or **Out of State GST** template that you have created based on the type of transaction
+5. Save and Submit the Invoice
+
+<img class="screenshot" alt="GST Invoice" src="{{docs_base_url}}/assets/img/regional/india/gst-invoice.gif">
+
+### Reports
+
+ERPNext comes with most of your reports you need to prepare your GST Returns. Go to Accounts > GST India head for the list.
+
+<img class="screenshot" alt="GST Menus" src="{{docs_base_url}}/assets/img/regional/india/gst-menu.png">
+
+You can check the impact of your invoice in the **GST Sales Register** and **GST Itemised Sales Register**
