Common GST return errors

Even if you have done everything correctly, there is still a small chance of inaccuracies, which could invite notices or fines. Below are some of the common errors businesses make while filing GSTR. These errors could be easily resolved with the help of any good GST software.

• When there is a mismatch between sales or purchase invoices when filing GSTR-1, GSTR-2A/2B, and GSTR-3B, it can lead to ITC denial.
• Using incorrect classification codes (HSN or SAC) can result in inaccurate tax calculation and compliance issues.
• These common mistakes include claiming the wrong ITC or missing eligible credits.
• The use of wrong GST rates on goods or services is a common error that affects the accuracy of returns.
• Filing after the due date costs interest and late fines, and can deny ITC until the filing is completed.
• Duplication of an invoice will increase the turnover and tax.
• Differences between GST returns and financial statements create compliance red flags.
• Refund claims might be affected by missing or incorrect shipping bill information on export invoices.

Now, let’s move on to the AI-based GST error detection tools.
