Whether you’re a startup or a seasoned enterprise, complying with GST laws is non-negotiable in India. Yet, many businesses unknowingly commit GST errors that can lead to notices, audits, penalties, or worse—legal action.
At Unlock Digi Services, we help businesses stay compliant by highlighting these critical GST errors and guiding them with proactive solutions.
Steps to Prevent Common GST Errors
The best way to avoid GST errors is to set up strong internal controls and consult with experts. Regular internal audits, automated reconciliation tools, and monthly compliance reviews can help identify discrepancies early. Use cloud-based accounting software integrated with GST filing tools to reduce manual entry mistakes. Additionally, training your accounts team on updated GST rules ensures your business stays compliant even as laws evolve. Don’t rely solely on external filing agents—understanding the basics of GST compliance can protect your business in the long run.
Claiming Incorrect Input Tax Credit (ITC)
Input Tax Credit (ITC) is one of the biggest benefits under GST—but it’s also one of the most misused.
Businesses often:
- Claim ITC on ineligible goods/services
- Claim ITC without valid invoices
- Mismatch ITC with GSTR-2B or GSTR-2A
According to GST laws, ITC claims must match the supplier’s filed returns. Discrepancies can trigger audits, penalties, and reversal of credit.
Tip: Reconcile ITC monthly using GSTR-2B data before filing GSTR-3B.
Delayed or Missed GST Return Filing
Filing GSTR-1, GSTR-3B, and other returns after the due date attracts late fees and interest. Repeated defaults may even lead to cancellation of GST registration.
Consequences of delayed GST return filing include:
- ₹50–100 per day in late fees
- 18% per annum interest on payable tax
- Suspension of GSTIN

Tip: Automate reminders and opt for professional filing support to never miss deadlines.
Not Issuing Proper Tax Invoices
A valid GST invoice must contain:
- GSTIN of both parties
- Invoice number and date
- HSN/SAC code
- Tax rate and amount
- Signature of the authorized person
Improper invoicing is one of the most frequent GST errors that can attract legal scrutiny, especially during departmental audits.
Tip: Use GST-compliant billing software or outsource invoicing to professionals.
Charging the Wrong GST Rate
Applying an incorrect GST rate—whether higher or lower—can lead to underpayment or over-collection, both of which are punishable under the law.
Example: Charging 5% GST on an item that falls under the 18% slab can lead to a shortfall in tax paid and additional interest.
Tip: Always check the latest GST rate slabs based on updated HSN/SAC codes.
Not Updating GST Registration Details
Have you:
- Changed your business address?
- Added a new business vertical?
- Shifted to a different state?
If yes, but haven’t updated your GST registration, you’re violating GST laws. This may lead to invalidation of invoices or cancellation of GSTIN during scrutiny.
Tip: Always file GST REG-14 for registration amendments within 15 days of any change.
Ignoring Department Notices
Many businesses ignore or delay responding to GST department notices. This is a serious error. Even a show cause notice (SCN) must be responded to within the stipulated period.
Common notices include:
- GSTR-3B vs GSTR-1 mismatches
- ITC reversal demand
- Non-filing of returns
- Turnover discrepancies
Tip: Take every notice seriously and respond through a certified tax expert or GST practitioner.
