Amend Uncertain GSTR-3B Transactions Using Return Effective Date in TallyPrime

While filing GSTR-3B returns, you may come across transactions in TallyPrime that are uncertain, mismatched, or missing details.

These transactions need to be corrected or amended before they can be included in your return.

TallyPrime offers a powerful feature called the Return Effective Date to help you handle such cases smoothly and in compliance with GST rules.

In this post, we will explain how to resolve and amend uncertain transactions in GSTR-3B using Return Effective Date, with simple examples.

1. What Are Uncertain Transactions in GSTR-3B in TallyPrime?

Uncertain transactions are those that TallyPrime cannot confidently classify under a specific GSTR-3B section.

This may be due to:

• Incomplete or missing GST details
• Wrong tax ledger or rate
• Missing place of supply
• Mismatched party GSTIN

Such transactions are shown under Uncertain Transactions in your GSTR-3B report.

2. Why Use Return Effective Date in TallyPrime?

If you identify and correct a transaction after the return period has ended, GST rules require that you report the correction in the month you noticed the error, not the original month.

TallyPrime lets you set a Return Effective Date, so the amendment is reflected in the correct return period without changing the actual transaction date.

3. Example 1: Correcting GST Rate in a Sales Invoice in TallyPrime

Let’s say you issued a sales invoice in May with a GST rate of 5%.

But the correct rate was 12%.

You discover this mistake in June.

1. Step-by-Step Solution:

1. Go to Gateway of Tally > Alter > Vouchers
2. Locate and open the May sales invoice
3. Update the correct GST rate (e.g., replace 5% with 12%)
4. Press Ctrl + I (More Details) > Select GST Details
5. Enter Return Effective Date as 1-Jun
6. Save the voucher

TallyPrime will now show this correction in June’s GSTR-3B report as an amendment.

4. Example 2: Updating Party GSTIN in a Purchase Invoice in TallyPrime

You recorded a purchase from a registered dealer in April but missed entering the supplier’s GSTIN.

You discover this in May.

1. Step-by-Step Solution:

1. Go to Gateway of Tally > Display > Daybook
2. Open the purchase voucher from April
3. Edit the party ledger and add the correct GSTIN
4. In the voucher, press Ctrl + I > GST Details
5. Set the Return Effective Date to 1-May
6. Save and accept

Now, TallyPrime will treat this as an amendment in May, and it will appear correctly in the GSTR-3B for May.
