India’s Premium Compliance StackGST Return Filing & ITC Reconciliation in India
GST return filing means reporting your outward supplies, tax liability, and input tax credit through the GST Portal, typically via GSTR-1/1A and GSTR-3B for regular taxpayers. ITC reconciliation compares your purchase records against GSTR-2B to catch mismatches before you claim credit, missing invoices, duplicate entries, and supplier errors are the usual culprits.
BookmyCA connects you with a Chartered Accountant who reconciles your records before filing, not after a notice arrives.
GST Return Filing & ITC Reconciliation at a Glance
GST return filing is how registered taxpayers report transactions, tax liability, and eligible input tax credit for a tax period. ITC reconciliation is the process of comparing your purchase register against GSTR-2B, a system-generated statement, to identify differences before you claim credit in GSTR-3B. GSTR-2B tells you what your suppliers have reported, it doesn't automatically mean everything in it is eligible for claim, that eligibility check is still yours to do.
Does GST Return Filing & ITC Reconciliation Apply to You?
Consider it when:
- You're a GST-registered business making taxable supplies and claiming input tax credit
- You're liable under reverse charge or deal with interstate purchases or imports
- You file under the QRMP scheme or hold multiple GST registrations
- You have significant purchase volumes, multiple suppliers, or frequent credit/debit notes
It may not suit you when:
- You have low transaction volume with a single, reliable supplier
- You have no interstate purchases, imports, or reverse charge transactions
- You've had no supplier filing delays or GST mismatches before
- You receive very few credit or debit notes
Not sure your filings and ITC claims reconcile? We can review your last cycle and flag mismatches early?

Common Mistakes
Filing GSTR-3B without reconciling ITC first.
Purchase register alone isn't enough, check GSTR-2B and eligibility conditions before filing
Treating GSTR-2B as automatic eligibility.
It's a reconciliation source, not a final determination, eligibility conditions still apply
Ignoring invoice and supplier mismatches.
Missing invoices or incorrect GSTIN need supplier follow-up, not silent write-off
Missing credit notes and amendments.
Reconcile original invoices together with amendments, not separately
Claiming duplicate ITC.
Invoice-level reconciliation catches this before filing, not after
Relying completely on auto-populated GSTR-3B.
It's a filing aid, you're still responsible for the figures being correct

Frequently Asked Questions
GSTR-1/1A for outward-supply reporting and GSTR-3B for summary liability and ITC. The exact forms and frequency depend on your registration type and filing scheme.
GSTR-2B is a system-generated statement showing available credit. ITC reconciliation is the broader process of comparing it against your purchase records and invoices to determine what's actually eligible.
It catches missing invoices, duplicate entries, supplier filing errors, and potentially ineligible ITC before you claim it, and builds an audit trail for later.
Investigate rather than assume either way. Common causes include supplier non-filing, incorrect GSTIN, invoice amendments, or timing differences, the right treatment depends on the specific cause.
Monthly GSTR-3B is generally due on the 20th of the following month. QRMP taxpayers generally file by the 22nd or 24th, depending on state. GSTR-1 has its own separate due dates. Always verify the current date and any extensions for your specific period.
