Top GST Filing Mistakes & How DisyTax Fixes Them

ITC Mismatch Errors

Problem: Purchases in GSTR-2A/2B don't match your books, leading to ITC reversal and tax demands.

DisyTax Solution: Our CA & Tax Lawyer team uses automated reconciliation tools to cross-verify every invoice, identify supplier non-compliance, and help recover blocked credits through GSTR-1A.

Wrong HSN/SAC Codes

Problem: Incorrect commodity codes result in wrong tax rates, notices from department, and financial penalties.

DisyTax Solution: Expert code validation with updated 8-digit HSN database, automatic rate verification, and compliance with latest GST amendments.

E-Way Bill Compliance Failures

Problem: Missing or incorrect E-Way Bills during goods movement lead to vehicle detention and heavy penalties.

DisyTax Solution: Integrated E-Way Bill generation with built-in compliance checklist, validity tracking, and real-time alerts before expiry.

Negative Liability Issues

Problem: Excess ITC claims over output tax causing cash flow blockage and complex refund procedures.

DisyTax Solution: Strategic carry-forward optimization, quarterly liability planning, and expert refund filing for exporters and inverted duty structures.

Missing Invoice Details

Problem: Incomplete B2B invoice information (GSTIN, address, POS) invalidates ITC claims.

DisyTax Solution: Pre-filing validation checks, amendment support through GSTR-1 amendments, and vendor compliance training.

Reverse Charge Mechanism Errors

Problem: Failing to pay tax under RCM for specified goods/services leads to interest and penalties.

DisyTax Solution: Automated RCM identification for GTA services, advocate fees, and other notified categories with proper tax liability booking.

GST Return Filing FAQs

What if I Miss GST Return Deadline? +

Missing GST deadlines attracts late fees of ₹100-200 per day (₹50 CGST + ₹50 SGST for GSTR-3B) with maximum caps varying by return type. Interest at 18% per annum is charged on delayed tax payments.

Penalty Waiver Options:

  • Nil returns have no late fees (₹20 waiver for NIL filing)
  • File within 15 days for reduced penalties
  • Request condonation for genuine hardship cases
  • Our emergency filing service ensures same-day submission to minimize penalties

Documents Required for GST Return Filing? +

Complete checklist for hassle-free GST filing:

  • Sales Data: Invoice-wise details with GSTIN, HSN/SAC codes, taxable value
  • Purchase Data: Supplier invoices, debit/credit notes, import bills of entry
  • Banking: Tax payment challans, bank statements for cash ledger verification
  • Previous Returns: Last filed returns, acknowledgments (ARN)
  • E-Way Bills: Copies for interstate sales >₹50,000
  • Digital Signature: DSC or EVC OTP for authentication

We provide Excel templates and direct ERP integration to simplify data collection.

Can Small Businesses File GST Themselves? +

While GSTN portal allows self-filing, professional assistance from CAs and Tax Lawyers is recommended because:

  • Complexity: Multiple return formats (GSTR-1, 3B, 9) with inter-dependencies
  • ITC Matching: Manual reconciliation of GSTR-2A/2B is time-consuming and error-prone
  • Compliance Risk: Incorrect entries trigger notices, penalties, and audit scrutiny
  • Time Investment: Average 8-12 hours per month for proper GST compliance

When to Outsource: Turnover >₹50 lakhs, multiple product lines, interstate supplies, or frequent ITC mismatches. Our ₹999 Basic Plan costs less than hiring an accountant.

GST Refund Process for Exporters? +

Exporters can claim refunds on accumulated ITC through two routes:

  1. With Payment of Tax: Pay IGST on exports → claim refund via Form RFD-01A within 2 years
  2. Without Payment (LUT): Export under Letter of Undertaking → claim accumulated ITC

Step-by-Step Process:

  • File monthly/quarterly GSTR-1 and GSTR-3B regularly
  • Ensure shipping bills are reflected in GSTR-2A
  • Submit RFD-01A with supporting documents (invoices, shipping bills, BRCs)
  • Track application status on GSTN portal
  • Refund credited within 60 days for 90% provisional sanctioning

Our refund filing service includes end-to-end documentation and follow-up with department.

Difference Between GSTR-1 and GSTR-3B? +

GSTR-1 (Outward Supplies): Invoice-level details of all sales (B2B, B2C, exports, debit/credit notes). Due 11th (monthly) or 13th (quarterly).

GSTR-3B (Summary Return): Consolidated summary of sales, purchases, ITC claims, and tax payment. Due 20th (monthly) or 22nd/24th (quarterly).

Key Difference: GSTR-1 shows transaction details; GSTR-3B is your final tax computation and payment return. Data in both must match to avoid mismatches.

How to Switch Between Monthly and Quarterly Filing? +

Taxpayers with annual turnover below ₹5 Crore can opt for QRMP (Quarterly Return Monthly Payment) scheme:

  • Login to GST portal → Services → Returns → Opt-in for Quarterly Return
  • Select applicable quarter (option available during first month of quarter)
  • Monthly tax payment via PMT-06 (5% of turnover or actual liability)
  • Quarterly GSTR-1 (13th) and GSTR-3B (22nd/24th) filing

Auto-Reversion: If turnover exceeds ₹5 Cr in any quarter, mandatory monthly filing from next quarter. We provide turnover monitoring alerts to prevent compliance gaps.

What is Input Tax Credit (ITC) and How to Claim It? +

Input Tax Credit allows businesses to reduce their output GST liability by claiming credit of GST paid on purchases and expenses.

ITC Claiming Conditions:

  • You must possess a valid tax invoice from supplier
  • Goods/services must be received
  • Supplier must have filed their GSTR-1 and your purchase should reflect in GSTR-2A/2B
  • You must have filed your GST returns
  • Tax charged must have been paid to the government by supplier

Blocked Credits: ITC is not available on motor vehicles (except for specific purposes), food/beverages, membership of clubs, and personal consumption items. Our team helps identify and maximize eligible ITC claims.

What Happens if Supplier Doesn't File GSTR-1? +

If your supplier fails to file GSTR-1, your purchases won't reflect in GSTR-2A/2B, preventing you from claiming ITC.

Actions You Can Take:

  • Contact supplier immediately and request them to file returns
  • Use GSTR-1A to add missing invoices (supplier must accept)
  • Report discrepancy through GST portal's grievance mechanism
  • If ITC is high-value, send legal notice to supplier
  • Reverse ITC temporarily in GSTR-3B and reclaim when supplier files

DisyTax's automated system tracks supplier compliance and sends alerts before ITC deadlines expire.

How to File Nil GST Return? +

Nil GST return is filed when there are no sales, purchases, or tax liability during a tax period.

Nil Return Filing Process:

  • Login to GST Portal with credentials
  • Go to Services → Returns → Select tax period
  • Click on 'Prepare Online' for GSTR-3B
  • All sections will show zero values
  • Verify details and submit with DSC/EVC
  • File within due date to avoid ₹20/day late fee

Important: Even with no business activity, nil returns are mandatory to maintain active GST registration status. Our automated reminders ensure you never miss nil return deadlines.

Can I Revise GST Returns After Filing? +

As per current GST law, there is NO provision to revise GSTR-1 or GSTR-3B after filing. However, corrections can be made in subsequent returns.

How to Correct Errors:

  • GSTR-1 Errors: Amend invoices in Table 9A/9B/9C of next month's GSTR-1
  • GSTR-3B Errors: Adjust figures in subsequent month's return
  • ITC Errors: Add/reduce ITC in next return with proper documentation
  • Tax Payment Errors: Pay differential tax with interest in next return

Annual Return (GSTR-9): This provides opportunity to reconcile entire year's data and make necessary adjustments. Our CAs and Tax Lawyers ensure error-free filing to avoid need for corrections.

What is Composition Scheme and Who Can Opt for It? +

Composition Scheme is a simplified tax scheme for small taxpayers with reduced compliance burden and lower tax rates.

Eligibility Criteria:

  • Annual turnover up to ₹1.5 Crore (₹75 lakhs for special category states)
  • Not engaged in inter-state supply of goods
  • Not an e-commerce operator or supplier through e-commerce
  • Not supplying non-taxable goods (alcoholic liquor, petroleum products)
  • Not a casual taxable person or non-resident taxable person

Tax Rates: 1% for manufacturers/traders, 6% for restaurants, 0.5% for other suppliers. File quarterly CMP-08 return with annual GSTR-4.

Limitation: Cannot charge GST on invoices and cannot claim Input Tax Credit.
