Query
I am getting message "Mismatch due to tax amount modified in voucher" in the GSTR reports. How to resolve it ?


Answer

The aforesaid message "Mismatch due to tax amount modified in voucher" generally appears due to incorrect TAX-RATE specified in ITEM Master or LEDGER Master.


Preface

The aforesaid message may appear in :
GSTR-1 (Sales / Outward Supply) and/or;

GSTR-2 (Purchase / Inward Supply) and/or;

GSTR-3 (Returns Summary).

Report : GSTR2

Message : Mismatch due to tax amount in voucher

Cause of Error : Incorrect Tax-Rate in ITEM Master


Solution 1 (Recommended)
- Use the option "Gateway of Tally >> Inventory Info >> StockItems >> Alter"
- Next, select the StockItem "Item A" and set the following options :

  1. Is GST Applicable : Yes
  2. Set GST details : Yes 
    - Taxability : Taxable
    - Integrated Tax : 18
    - Next, press Ctrl+A (to accept and close the window)
  3. Type of Supply : Goods (or Services)
  4. Press Ctrl+A to accept and save the StockItem.


IMPORTANT

a. If you are using Accounting-with-Inventory (i.e. Stockitems in Sales/Purchase entries), then it is advised that you specify the HSN code and Tax-rates at the StockItem level only (and not the Sales ledger-level).

b. Specifying the GST Tax rates at one place (i.e. Stockitem level) simplifies the whole process.


PS:

The aforesaid message / problem may occur in "Sales with StockItems" or "Purchase with StockItems". The steps to resolve are the same for both Sales and Purchase entries.
