## How to Implement GST or Other Taxes Based on Price Slabs in Purchase?

In **Logic ERP**, you can automate tax recalculations in **purchase transactions** when linked tax types are defined. This ensures accurate **GST application** based on item values, preventing tax calculation errors.

### **Linking Tax Types Based on Rates**

* Navigate to the Setup and expand Setup Taxes 
* Then click on **Link Tax Types (Rate Basis) - Purchase.**

* Predefined tax settings apply GST based on item value:
  * **Apparel:**
    * **₹1000 or less** → **5% GST**
    * **Above ₹1000** → **12% GST**
  * **Footwear:**
    * **₹1000 or less** → **12% GST**
    * **Above ₹1000** → **18% GST**

### **Issue Without Auto-Refreshing Taxes**

* Create a **Purchase Entry** without enabling the feature.
* If an **apparel item** is entered at **₹500**, GST of **5%** applies.
* When the price is later **increased to ₹1100**, the tax remains unchanged, leading to errors.

### **Enabling Auto-Refresh for Taxes**

* Navigate to the **Purchase Voucher Configuration.**
* Under **Other Settings 2**, locate the option **"Linked Tax Types".**

* Three options are available:
  1. **Not Applicable** (Default) → Taxes remain unchanged.
  2. **Refresh Row Wise** → Taxes update instantly when the rate changes.
  3. **Refresh Before Save** → Taxes update only upon saving the voucher.

### **How Auto-Refresh Works**

* **Using "Refresh Row Wise"**:
  * If an item is entered at **₹500**, GST of **5%** applies.
  * If the price is updated to **₹1200**, the GST **automatically updates** to **12%**.
* **Using "Refresh Before Save"**:
  * Enter an item with **₹500** (5% GST).
  * Change the rate to **₹1300** and save the voucher.
  * The system updates GST to **12%** after saving.

### **Conclusion**

This feature in **Logic ERP** ensures **automatic GST updates** based on item value, preventing tax miscalculations and ensuring compliance with tax regulations.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
