GST Return Filing by Accountant

GST Return Filing by Accountant

Every GST-registered person must furnish the returns and statements applicable to their registration type, filing frequency, turnover, and activities. Accurate filing involves more than entering totals—it requires invoice review, tax calculation, input-tax-credit reconciliation, ledger checks, and timely payment.

An experienced accountant can organise the underlying records, reconcile GSTR-1 with GSTR-3B and GSTR-2B, identify ineligible or reversible credit, and help prevent mismatches that may lead to notices, interest, or late fees.

LegallensIndia provides recurring GST return-filing assistance with dedicated compliance support, structured data collection, return preparation, reconciliation, filing reminders, and status reports.

What is a GST Return?

A GST return is an electronic statement containing the information prescribed for a registered person's tax period. Depending on the form, it may report outward supplies, inward supplies, tax liability, input tax credit, tax deducted or collected, refunds, or annual and final-return particulars.

The net GST payable is determined after considering output tax, eligible input tax credit, reverse-charge liability, prior-period adjustments, interest, late fee, and the permitted order of utilisation of electronic ledgers.

A GSTIN does not file every form in the GST system. The applicable return set depends on whether the registration is regular, composition, non-resident, ISD, TDS, TCS, OIDAR, UIN, or another specified category.

What GST Return Filing Includes

• Sales and Outward Supplies: Invoice, debit-note, credit-note, advance, export, SEZ, exempt, and reverse-charge reporting.
• Purchases and Inward Supplies: Review of purchase registers, vendor filings, imports, and reverse-charge transactions.
• Output Tax: Classification, place of supply, tax rate, taxable value, and CGST, SGST, UTGST, IGST, or cess computation.
• Input Tax Credit: Reconciliation with GSTR-2B and invoices, eligibility checks, reversals, reclaims, and blocked-credit review.
• Tax Payment: Set-off through electronic credit and cash ledgers in the permitted order.
• Compliance Records: Return acknowledgements, challans, reconciliation workings, and exception reports.

Who Should File GST Returns?

Every registered person must file the forms assigned to that GSTIN unless specifically exempted. Filing can remain compulsory even when there are no transactions during a tax period.

• Regular taxpayers filing monthly or under the QRMP scheme.
• Composition taxpayers filing CMP-08 and the applicable annual return.
• Casual and non-resident taxable persons.
• Input Service Distributors.
• GST TDS deductors and TCS-collecting e-commerce operators.
• Specified overseas OIDAR service providers.
• UIN holders, exporters, SEZ registrants, and other specialised registrations where the relevant form applies.

Registration thresholds determine when registration may be required; they do not ordinarily remove return obligations after a GSTIN has been granted. Cancellation or suspension must be handled through the prescribed process rather than by simply stopping return filing.

Common GST Returns and Statements

GSTR-2A and GSTR-2B

GSTR-2A and GSTR-2B are auto-drafted statements, not returns filed by the recipient. They support purchase and input-tax-credit reconciliation.

• GSTR-2A: A dynamic statement that changes as suppliers and other reporting sources furnish or amend data.
• GSTR-2B: A static statement generated for a tax period and used as a primary reference for ITC review.
• Eligibility Still Matters: Appearance in an auto-drafted statement does not by itself make credit eligible; statutory conditions and restrictions must also be satisfied.
• Missing Invoices: Differences should be followed up with vendors and resolved within the applicable time limits.

Forms GSTR-2 and GSTR-3 from the original return design remain deferred and are not part of the routine current filing workflow.

Regular Taxpayer Filing Cycle

GSTR-1: Outward Supplies

Monthly filers generally furnish GSTR-1 by the 11th of the following month. QRMP taxpayers generally furnish it by the 13th after the quarter. Extensions may be notified.

GSTR-1A: Optional Same-Period Correction

After GSTR-1 is filed or its due date arrives, whichever is later, an eligible taxpayer may use GSTR-1A to add or amend same-period supply records before filing GSTR-3B.

GSTR-3B: Summary and Tax Payment

Monthly filers generally furnish GSTR-3B by the 20th of the following month. QRMP filers generally use the 22nd or 24th after the quarter according to the principal place of business.

QRMP Monthly Payment

Eligible QRMP taxpayers generally deposit tax for the first two months of a quarter using Form PMT-06 by the prescribed date and file quarterly GSTR-1 and GSTR-3B.

Invoice Furnishing Facility

IFF is optional for QRMP taxpayers and permits specified B2B invoices and debit or credit notes for the first two months of a quarter to be furnished within the prescribed window.

Indicative GST Return Due Dates

The dates below are the general statutory schedule. Extensions, taxpayer-specific orders, holidays, and Portal advisories should be checked for each period.

Documents Required for Accountant-Assisted Filing

• GST Portal credentials and authorised-signatory access.
• Sales and purchase registers with invoice-level details.
• Tax invoices, debit notes, credit notes, delivery challans, and advance records.
• GSTR-1, GSTR-3B, GSTR-2B, and electronic ledger downloads.
• Import bills of entry, export documents, LUT records, and SEZ endorsements where applicable.
• Reverse-charge, blocked-credit, ITC-reversal, and reclaim workings.
• E-invoice and e-way bill reports for reconciliation.
• Bank, expense, fixed-asset, and accounting records relevant to GST.

GST Return Filing Process

Step 1: Determine the Filing Profile

Confirm the GST registration type, return frequency, QRMP status, turnover, States of registration, e-invoice applicability, and specialised return obligations.

Step 2: Collect and Validate Data

Obtain complete sales, purchase, expense, import, export, credit-note, debit-note, advance, and reverse-charge information for the tax period.

Step 3: Reconcile Outward Supplies

Compare the sales register with e-invoices, e-way bills, prior returns, and proposed GSTR-1 data. Resolve invoice, tax-rate, place-of-supply, and amendment differences.

Step 4: Reconcile Input Tax Credit

Match purchase records with GSTR-2B, verify statutory conditions, identify blocked or reversible ITC, and track missing vendor invoices.

Step 5: Prepare and Review GSTR-1

Classify and upload the outward-supply details, generate the summary, review exceptions, and file the statement using the authorised verification method.

Step 6: Calculate GSTR-3B

Reconcile outward liability with GSTR-1, determine eligible ITC and reverse charge, consider interest or prior adjustments, and calculate the net cash requirement.

Step 7: Pay and File

Create a challan where necessary, offset liabilities in the permitted order, verify GSTR-3B through DSC or EVC, and preserve the ARN.

Step 8: Issue a Compliance Report

Maintain filed-return copies, challans, ledger extracts, mismatch lists, vendor follow-ups, and action points for the next tax period.

Consequences of Late or Incorrect Filing

• Late Fee: The Portal may calculate a per-day late fee subject to the form-specific cap and applicable relief notifications.
• Interest: Delayed tax payment can attract statutory interest, with the calculation depending on the nature of the liability and applicable provision.
• Return Blocking: Non-filing of earlier returns can restrict later return filing and other Portal facilities.
• ITC Impact: Supplier non-compliance or reporting errors can affect a recipient's credit visibility and commercial relationships.
• Notices and Assessment: Persistent non-filing or mismatches can result in notices, best-judgment assessment, demand, recovery, or registration action.
• E-Way Bill Restrictions: Continued default can block e-way bill generation under the applicable rules.

Late fees are not universally ₹200 per day or capped at one fixed amount. The applicable form, nil-return status, turnover, tax period, and relief notification must be checked before quoting a liability.

Benefits of Filing Through an Accountant

• Dedicated Review: A professional reviews transactions instead of relying only on Portal-populated totals.
• Better Reconciliation: GSTR-1, GSTR-3B, GSTR-2B, books, e-invoices, and e-way bills are compared regularly.
• ITC Control: Eligible credit, blocked credit, reversals, reclaims, and vendor mismatches are tracked.
• Deadline Management: A return calendar and reminders reduce the risk of missed filing and payment dates.
• Document Trail: Filed returns, challans, ledgers, and supporting workings remain organised for notices and annual reconciliation.
• Management Visibility: Periodic reports show filing status, tax outflow, unresolved differences, and required corrective action.
