Businesses across India rely on proper information of taxes to ensure that their books remain clean and they do not receive any unwanted notices. Errors in GST Online Verification often result in confusion, unpassed vendor check and delay in filing. Many taxpayers rush through the process and miss little things that matter. A mere legal name mismatch or lack of registration update can throw a spanner in the normal operations.
This blog gives you an idea of what you should avoid so that your validation will be smooth and trustworthy. The goal is to ensure traders, retailers, distributors or service providers are able to deal with their verification confidently while remaining compliant with regulations in respect of GST rules in their respective states.

Common Mistakes Taxpayers Must Avoid
Ignoring Basic Registration Details
Many businesses do not carry out basic checks in the validation of a supplier. This comes as a problem during audits and monthly returns. Key errors include:
- Using outdated legal names at the time of entry of a supplier's details.
- Failure to check the status code on the portal before raising invoices.
- Wrong state codes entered during purchase entry.
- Not verifying the format of the GSTIN and saving it in the accounting tools.
A textile unit based at Surat used to continue with transactions with a partner from whom the registration had become inactive. The problem was realized only when a departmental enquiry was conducted and this caused avoidable stress. A laid-back review of all fields would have prevented this.
Overlooking Portal Status and Compliance Signals
Not Checking the Latest Status
The activities of the GST portal constitute the real-time status update. Many taxpayers only take note of the GSTIN and do not check the activity flag. During verification, many times the taxpayers miss:
- Notices are issued to the supplier on the portal.
- Suspended comments: remarks from the website moderator.
- Cancelled register records if dues to be paid
- History of returns that have been filed and delays that are visible on the dashboard.
A supplier based in Pune had received repatriation of his orders, order after order, from a wholesale dealer in groceries, despite cancellation. The dealer had used old data that was saved months before. Such issues are prevented by revisiting the portal before each big order.
Skipping Activity and Location Checks
Verification is not just to confirm the validity of GSTIN. Taxpayers need to make sure the nature of the business that provides the goods or services coincides with the goods or services being bought.
- Business activity presented on the portal does not correspond to the invoice provided.
- The principal place of business is different from the one where we have put on the invoice.
- Additional place of business missing for large distributors.
- HSN or SAC codes do not matching goods being billed.
A dealership in electronics in Chennai once encountered ITC blocking issue as the activity registered by their supplier had nothing to do with the items that were being sold. A brief review of the field of activities would have avoided the mismatch.
Not Matching PAN Records Correctly
Many of the taxpayers fall into GSTIN through verbal communication or by using old purchase bills. They do not conduct proper checks during validation. Some important things that are overlooked:
- PAN of the entity & GSTIN prefix does not match.
- Legal name is miss typed at the time of entering the supplier's records.
- Trade name is confused with legal name which causesa mismatch in filing.
- Registration or temporary ID's being passed of as regular GSTIN.
These errors bring about discrepancies while performing reconciliation. A Nagpur furniture retailer once encountered problems of return mismatch because the legal name of one of their suppliers had a spelling error that was carried over in all of the entries. By one corrected check, they were saved from a notice.
Not Using the GST Portal for Final Confirmation
Many taxpayers, therefore, rely completely on screenshots from vendors or accountants' post. This paves the way for human error.
- Data may be outdated.
- Portal updates are not always reflected in previous screenshots.
- Incorrect assumptions may be made because of partial visibility.
- The historical compliance notes are hidden within screenshots.
A Chemical distributor in Vadodara received a screenshot of "Active" status. However, the portal had already flagged the supplier as "Suspended due to non-filing". Direct verification on the portal would have provided the clarity.
Not Checking Address Details Carefully
Small errors at the address level tend to escape notice. These consist of major during assessments or cross-checks. Common mistakes related to addressing are:
- Not matching of a registered state with the state code used.
- Entering details of branch offices as main office details.
- Missing unit numbers within multi-warehouse setups.
- Not making additional places of business for review.
A Hyderabad courier partner had an occasion when they used warehouse details instead of the primary registered address and it mismatched in e-way bill generation. A simple review of address fields would have made up the issue in zero time.
Conclusion
Taxpayers from all parts of India make the mistake of not calculating the impact of small mistakes at the stage of GST online verification process. Wrong digit, obsolete status or loss of portal alert can make ITC and compliance problems during audits. Careful checks are useful for ensuring good records and trust between suppliers and buyers. Always check each of the details on the official portal than relying on assumptions.
Monitor business activity fields, registration status, PAN alignment and address information and do care. Take time to check in on entries before saving them. These habits make for a safer and more seamless journey in GST filed by each business in size and sector.
