The GST portal does not impose a standard ₹500–₹10,000 ‘return filing fee’ for filing an on-time return yourself. What businesses pay is usually professional or software cost, plus any tax, interest and statutory late fee. Obtain a scope-based quote using registration count, return types, invoice volume, reconciliation and notice work.
How this 2026 guide was prepared
The supplied draft was treated as a topic brief, not as legal authority. Outdated portal dates, overbroad thresholds, invented procedures and incorrect rate or format claims were corrected against official GST, CBIC, GST Council and India Code materials available on 2026-07-28.
Effective-date warning: GST rates, exemptions, portal screens and due dates can change. Confirm the live notification and return period before acting.
Five costs often mixed together
Separate output tax and cash payment, statutory interest, statutory late fee, professional service fee, and software or accounting cost. Calling all five ‘GST return fees’ makes comparisons unreliable and can hide the real compliance failure.
Why the supplied price bands are unsafe
There is no official monthly professional tariff for small, medium and large businesses. A low-turnover company can have complex exports or multiple GSTINs; a large firm may have automated data. Quotes should be labelled indicative, dated and inclusive or exclusive of tax—not presented as government-set charges.
What drives professional effort
Count GST registrations, filing frequency, GSTR‑1 documents, GSTR‑3B reconciliation, e-commerce statements, reverse charge, imports, exports, ISD, TDS/TCS, amendments, credit notes, e-invoices, annual return, refund and notices. Data quality and the number of corrections often matter more than turnover.
Late fee and interest
Late fee is calculated under section 47 and may be capped or reduced by notification for particular returns and periods. Interest under section 50 is a separate charge and depends on the default. Always use the portal liability and current notification rather than a timeless blog figure.
DIY versus professional filing
DIY can work for a simple, well-reconciled business with capable staff. Professional review is valuable where classification, place of supply, ITC eligibility, e-commerce, exports, multiple registrations or notices are involved. Outsourcing data entry without reconciliation does not transfer legal responsibility.
A fair quote checklist
Ask for included GSTINs and returns, monthly invoice volume, reconciliation depth, books cleanup, e-invoice and e-way support, amendment handling, annual-return scope, notice representation, turnaround, client responsibilities, data security, exclusions and GST on the professional fee.
Need a transaction-specific GST review?
