How much does GST return filing cost?

Professional service fees for Goods and Services Tax (GST) compliance in India are not arbitrary flat numbers. Because indirect tax mandates hold directors and business owners personally liable for mismatched tax credits and overdue returns, professional retainer fees vary proportionally with the administrative complexity and audit exposure of each entity.

At ADEQUS, we price professional filings through an objective formula based on seven structural cost drivers:

1. Filing Frequency & Taxpayer Scheme Periodicity

Regular taxpayers filing monthly GSTR-1 and GSTR-3B have 24 mandatory annual touchpoints, whereas QRMP (Quarterly Return Monthly Payment) schemes require 4 quarterly returns plus monthly PMT-06 challans.

2. Transaction & Invoice Volume Data Processing

A business generating 15 invoices per month requires minimal data validation, whereas operations with 500+ monthly B2B sales invoices require line-item HSN/SAC code mapping, taxable value checks, and e-way bill reconciliation.

3. Input Tax Credit (ITC) Reconciliation Depth GSTR-2B Matching

Rule 36(4) of the CGST Rules limits ITC claims strictly to invoices reflected in GSTR-2B. Reconciling inward purchase registers against supplier portal filings safeguards against future departmental recovery notices (DRC-01C).

Additional Complexity Factors That Affect Service Charges

Special Transaction Regimes: E-commerce marketplace sales (Amazon/Flipkart with TCS), SEZ/Export supplies with or without LUT, and Reverse Charge Mechanism (RCM) liabilities require distinct portal tables.
Multiple GSTIN Registrations: Entities operating in multiple states require separate state-specific returns. Additional GSTINs are handled at an economical 50% incremental rate per branch.
Amendments & Previous Table Corrections: Rectifying omitted invoices from earlier tax periods (Tables 9A/9C of GSTR-1 or Table 4 of GSTR-3B) requires multi-period ledger tracking.
Pending / Backlog Returns: Entities with delinquent non-filed periods require systematic sequential filing to unblock portal access and restore e-way bill generation privileges.
Clear Distinction on Government vs. Professional Fees: ADEQUS fees cover expert preparation, verification, and filing by tax specialists. Statutory late fees (₹20/day for Nil, ₹50/day for regular returns) and 18% annual interest on delayed tax liabilities are payable directly to the government treasury.

Understanding Statutory GST Return Types

Compliance under the Goods and Services Tax Act revolves around three interdependent pillars of reporting:

GSTR-1

Outward Supply Reporting

The monthly or quarterly return through which registered suppliers report all sales, credit notes, export invoices, and B2B supplies with recipient GSTINs. Filing GSTR-1 timely enables your buyers to claim input tax credits in their GSTR-2B.

Due: 11th / 13th of following month
GSTR-3B

Summary Return & Settlement

The self-assessed monthly summary return where net tax liabilities are offset using available Input Tax Credit (ITC) balance and cash ledger deposits. Accurate filing ensures zero penal interest under Section 50 of the CGST Act.

Due: 20th of following month
GSTR-2B

ITC Reconciliation Reference

An auto-drafted, static statement generated on the 14th of every month. It reflects available and unavailable tax credits based on your vendors' GSTR-1 submissions, serving as the official benchmark for lawful ITC claims.

Generated: 14th of every month
Frequently Asked Questions

Common Inquiries About GST Compliance Fees

Every B2B sales invoice requires validation of buyer GSTIN validity, HSN/SAC classification, appropriate tax rate selection (0%, 5%, 12%, 18%, 28%), place of supply rules, and e-invoice JSON generation if applicable. As invoice volume increases, professional review hours and reconciliation workloads scale accordingly.
A Nil return can only be filed when there are zero sales, zero purchases, zero credit/debit notes, and zero pending tax liabilities. If your bank statement reflects taxable business credits or purchases, filing a Nil return constitutes a false declaration under the GST Act, attracting notices under Section 73/74. ADEQUS verifies your bank transactions prior to Nil filing confirmation.
No. This calculator estimates ADEQUS professional service charges only. If returns are filed past the statutory due dates, the GST portal automatically calculates government late fees (₹20 to ₹50 per day) and 18% annual interest on net tax liabilities, which are deposited directly to the government via PMT-06 / CPIN payment challans.
