Description
TCS Calculator is a powerful Chrome Extension designed to assist Online Sellers and Accounting Professionals in accurately calculating, reconciling, and comparing TCS (Tax Collected at Source) credit data between the GST Portal (https://www.gst.gov.in) and gstproseller.com.
The core functionality of this tool is to match the TCS amounts declared by eCommerce platforms (such as Meesho, Amazon, Flipkart, etc.) with the amounts reported by the seller in their GST filings. It helps detect discrepancies, ensures correct reporting, and safeguards against the loss of eligible credits.
The extension simplifies the reconciliation process by automatically fetching and comparing relevant data, eliminating the need for manual matching or complex spreadsheets. Ideal for online sellers, it enhances accuracy, improves compliance, and saves valuable time during GST return preparation.
How to Use:
1. Log in to gstproseller.com and add your GST profile.
2. Upload the sales report downloaded from your eCommerce platform and generate a statement.
3. Log in to the GST Portal and navigate to the TCS Credit Received section.
4. Click on the TCS Calculator Extension and click on “Compare TCS Details”.
