The cost savings from India’s new GST return filing system are real, and if your business is still paying what it paid for GST compliance in 2019, you are almost certainly overpaying. Between the QRMP scheme, auto-populated GSTR-2B, the invoice furnishing facility, and e-invoicing, the compliance burden for most Indian businesses has dropped significantly. This article breaks down exactly where those savings come from, how much you can realistically expect to save, and what you should do to capture them in 2026.
How GST return filing has evolved
When GST launched in July 2017, the intent was a three-return system: GSTR-1 (outward supplies), GSTR-2 (inward supplies, supplier-matched), and GSTR-3 (consolidated monthly return). The problem was that GSTR-2 required buyers and sellers to cross-match every invoice manually. The system collapsed under its own complexity and GSTR-2 was suspended within months of launch.
What followed was years of patching. Businesses filed GSTR-1 and GSTR-3B separately, with no automated reconciliation between the two. Reconciling Input Tax Credit (ITC) required manual comparison of your purchase register against your suppliers’ GSTR-1 filings, a process that consumed dozens of hours a month for mid-size businesses and significant CA fees for small ones.
From 2020 onward, the system shifted meaningfully. GSTR-2B (auto-populated ITC statement), the QRMP scheme, the invoice furnishing facility (IFF), and mandatory e-invoicing for larger businesses changed the structure of compliance. The result, for most eligible businesses, is fewer filings, less manual work, and lower professional fees. These are the cost savings from the new GST return filing system that matter most for your bottom line.
| Feature | Old GST filing system (2017-2019) | Current simplified system (2024-2026) |
|---|---|---|
| Return frequency (small businesses) | 12 GSTR-1 + 12 GSTR-3B per year = 24 returns | 4 GSTR-1 + 4 GSTR-3B (QRMP) + 12 PMT-06 = 20 filings, less manual effort |
| ITC reconciliation | Manual match of purchase register vs supplier filings | Auto-populated GSTR-2B; one-click review |
| Invoice submission (small filers) | Full GSTR-1 monthly, even for 5-10 invoices | IFF for B2B invoices in Q1 and Q2 months; quarterly GSTR-1 for Q3 |
| GSTR-1 data entry (large businesses) | Manual entry of all invoices | Auto-populated from e-invoices via IRP |
| Late fee structure | Uncapped accumulation common; large arrears for small filers | Capped late fees under CBIC amnesties and rationalisation |
| Multi-GSTIN reporting | Completely separate filings per GSTIN | Consolidated reporting dashboards available on GST portal |
Cost saving 1: QRMP scheme for small taxpayers
The Quarterly Return Monthly Payment (QRMP) scheme applies to businesses with annual aggregate turnover up to ₹5 crore. Instead of filing GSTR-1 and GSTR-3B every month, you file these returns quarterly. You still pay tax monthly via PMT-06, but the actual return preparation and submission drops from 24 filings a year to 8.
For small businesses, the biggest compliance cost is not the government fee (which is zero for most returns) but the time spent preparing and the CA or accountant fees charged per filing. Reducing filing frequency by one-third directly reduces those costs. If your CA charges ₹1,500-2,000 per return, switching to QRMP saves you ₹12,000-16,000 per year on return filing alone.
QRMP is opt-in and auto-renewed annually. If you are currently filing monthly and your turnover is under ₹5 crore, check whether you are already opted in at the GST portal under the “QRMP” section. If not, you can switch at the end of any quarter.
Cost saving 2: Auto-populated GSTR-2B cuts reconciliation time
GSTR-2B is a static auto-populated ITC statement generated for each taxpayer on the 14th of every month. It pulls data from your suppliers’ GSTR-1, GSTR-5, and GSTR-6 filings and shows you exactly what ITC you are eligible to claim, organised by invoice.
Before GSTR-2B, businesses had to download their purchase register, download their suppliers’ GSTR-1 data from the portal (called GSTR-2A, which was dynamic and changed daily), and manually reconcile line by line. For a business with 100-200 purchase invoices per month, this took 8-15 hours of accountant time per month. At ₹500-800 per hour for a junior accountant or bookkeeper, that was ₹4,000-12,000 per month in reconciliation costs alone.
GSTR-2B does not eliminate reconciliation entirely, but it drastically reduces it. The mismatches you need to manually chase are now a fraction of total invoices, not the entire list. For GST registration in India seekers and newly registered businesses especially, starting with GSTR-2B from day one means never building the bad habit of fully manual reconciliation.
Cost saving 3: Invoice furnishing facility removes the need for CA involvement in routine uploads
Under QRMP, small businesses use the Invoice Furnishing Facility (IFF) to upload B2B invoices in the first two months of a quarter, so that their buyers can claim ITC without waiting until the quarterly GSTR-1 is filed. The third month’s invoices go directly into the GSTR-1.
The IFF interface is simpler than the full GSTR-1 filing. For businesses with straightforward B2B transactions, uploading invoices via IFF does not require a CA. You can do it yourself through the GST portal or via GST Suvidha Providers (GSPs) and accounting software. The SMS-based filing option for nil returns further reduces dependency on professionals for routine compliance.
The practical saving: if you were paying a CA ₹2,000-3,000 per month purely to upload invoices and file GSTR-1, IFF gives you the option to handle that in-house for mid-months and only engage professional help for the quarterly return where more judgment is needed.
Cost saving 4: Rationalised late fees reduce penalty exposure
One of the most overlooked gst compliance cost reductions is the rationalisation of late fees by the CBIC. Historically, small businesses that missed return deadlines accumulated large late fee arrears with no cap, creating a debt trap that made it uneconomical to resume compliance.
The current structure caps late fees as follows for small taxpayers:
- For GSTR-3B: Late fee is ₹50 per day (₹25 CGST + ₹25 SGST) for returns with tax liability, and ₹20 per day for nil returns.
- For GSTR-1: Late fee is ₹50 per day for returns with outward supplies, ₹20 per day for nil returns.
- CBIC has also run multiple amnesty schemes that waived accumulated late fees for lapsed filers, most recently in 2024-25, allowing businesses to get back into compliance without clearing years of penalties first.
For any business that went dormant during COVID-19 and has not filed returns since, checking the current amnesty window and clearing the backlog now, at capped fees, is significantly cheaper than waiting. Refer to the CBIC GST instructions 2026 for the latest CBIC circulars on fee waivers.
Cost saving 5: E-invoicing eliminates data entry errors for mid-size businesses
E-invoicing (electronic invoicing via the Invoice Registration Portal) is now mandatory for businesses with annual turnover above ₹5 crore. When you generate an e-invoice, the Invoice Reference Portal (IRP) assigns it an Invoice Reference Number (IRN) and pushes the data directly into your GSTR-1 auto-population. You do not re-enter invoice data into your GSTR-1 manually.
The gst filing cost savings here come from two places. First, data entry time drops to near zero for covered invoices. Second, the elimination of manual entry removes the most common source of errors in GSTR-1, which means fewer amendments, fewer officer queries, and no reconciliation gaps caused by mistyped invoice numbers or amounts.
Amendments to GSTR-1 are chargeable by most CAs and accountants as additional work. A business that makes 8-12 amendments per quarter at ₹300-500 per amendment saves ₹2,400-6,000 per year just from error elimination under e-invoicing. The reduction in officer-raised queries further reduces the professional time spent on responses.
Cost saving 6: Consolidated reporting for businesses with multiple GSTINs
Businesses registered across multiple states have a separate GSTIN for each state. Historically, each GSTIN required entirely separate return preparation and filing, and tracking ITC across GSTINs was done through spreadsheets or expensive ERP configurations.
The GST portal now provides a consolidated dashboard view across all GSTINs under a single PAN. While returns still have to be filed per GSTIN, the data visibility layer reduces the time compliance teams spend pulling information from multiple logins. For finance teams managing 5-10 GSTINs, this consolidation can reduce the monthly reporting overhead by 20-30%, particularly for monthly reconciliation and cash flow tracking across registrations.
If your business needs GST registration in new states, using a virtual office address for your GST at PPOB and APOB address helps keep the address compliance costs low while the portal improvements reduce the ongoing filing overhead.
What compliance actually costs: old system vs new system
| Business size | Annual turnover | Old system monthly cost (est.) | New system monthly cost (est.) | Annual saving |
|---|---|---|---|---|
| Freelancer / micro | Under ₹20 lakh | ₹1,500 (CA fees, GSTR-1 + 3B monthly) | ₹500 (quarterly returns, nil IFF months self-filed) | ₹12,000 |
| Small business | ₹20 lakh to ₹1 crore | ₹3,000 to ₹5,000 (monthly filings + manual ITC reconciliation) | ₹1,500 to ₹2,500 (QRMP + GSTR-2B auto-population) | ₹18,000 to ₹30,000 |
| Mid-size business | ₹1 crore to ₹5 crore | ₹8,000 to ₹12,000 (monthly returns + reconciliation + amendments) | ₹4,000 to ₹6,000 (QRMP or monthly with GSTR-2B + IFF) | ₹48,000 to ₹72,000 |
| Large business | Above ₹5 crore | ₹20,000 to ₹40,000 (monthly, manual GSTR-1, full reconciliation) | ₹12,000 to ₹20,000 (e-invoicing auto-population, GSTR-2B, portal dashboards) | ₹96,000 to ₹2.4 lakh |
Note: These are estimates based on typical CA and accountant fee structures for Indian SMEs. Actual savings depend on your invoice volume, number of GSTINs, and whether you have in-house accounting capability. Businesses with in-house finance teams will see savings primarily in staff hours rather than direct CA fees.
Limitations: what the new system does not solve
The gst return simplified system is a genuine improvement, but it does not eliminate all compliance friction.
- QRMP still requires monthly tax payment via PMT-06. If you miscalculate your monthly payment (whether using the fixed sum method or self-assessment), you will pay interest at 18% per annum on the shortfall. The quarterly return does not mean quarterly cash outflow.
- GSTR-2B mismatches still occur. If your supplier files their GSTR-1 late or with errors, the mismatch does not disappear. You will need to reverse the ITC claim or chase the supplier, which takes time and sometimes professional help. GSTR-2B reduces the volume of mismatches but does not eliminate them.
- E-invoicing has implementation costs upfront. Switching to e-invoicing requires either integration with an IRP-connected ERP system or use of a GSP. For businesses without existing accounting software, this is a setup cost that offsets early savings.
- Reconciliation gaps between GSTR-1 and GSTR-3B can still attract officer scrutiny. The portal now flags significant differences, and businesses need to be consistent in how they report supplies across returns.
How to maximise your compliance cost savings in 2026
- Check your QRMP status immediately. Log into the GST portal, navigate to “Services” and then “Returns”, and confirm whether you are opted into QRMP. If your turnover is under ₹5 crore and you are still filing monthly, switch at the start of the next quarter.
- Use GSTR-2B as your primary ITC source. Stop maintaining a separate manual reconciliation if GSTR-2B covers your suppliers. Only investigate specific line items that show a mismatch, rather than reconciling the full register every month.
- Review your CA’s fee structure. If your CA charges per-return flat fees that have not been adjusted for the QRMP reduction in return count, renegotiate. Monthly fees set under the old 24-return-per-year structure are not appropriate for a business now filing 8 returns per year.
- Adopt accounting software with IRP integration if your turnover is above ₹5 crore. The cost of software (₹5,000-15,000 per year for SME-tier tools) is recovered within months through reduced data entry and amendment costs.
- Clear any pending late fee arrears under current CBIC amnesty provisions before the window closes. Refer to the latest CBIC notifications for the applicable dates and waiver amounts.
Reducing costs further with virtual office addresses
Businesses that operate across multiple states and maintain separate GSTINs for each location carry both the filing burden and the cost of maintaining commercial addresses in each state. One practical way to reduce the address-related compliance overhead is to use virtual office addresses for Additional Places of Business (APOB) rather than leasing physical space. myHQ Virtual Office provides GST-compliant commercial addresses across 25+ cities in India, including the rent agreement and NOC documentation required for GST registration, without the overhead of a physical lease.
Frequently asked questions
Who is eligible for the QRMP scheme?
Any registered taxpayer with an annual aggregate turnover of up to ₹5 crore in the preceding financial year is eligible for QRMP. You can opt in or out at the start of any quarter through the GST portal. If you do not actively opt out, QRMP registration auto-renews each financial year.
Does GSTR-2B replace GSTR-2A?
GSTR-2A is a dynamic, continuously updated statement that reflects your suppliers’ filings in real time. GSTR-2B is a static snapshot generated on the 14th of each month, used specifically for ITC claims in that month’s GSTR-3B. For reconciliation and ITC claiming purposes, GSTR-2B is now the primary document. GSTR-2A still exists for reference but is not used directly for ITC in GSTR-3B.
Is e-invoicing mandatory for all businesses in 2026?
As of 2026, e-invoicing is mandatory for businesses with annual turnover above ₹5 crore. Businesses below this threshold are not required to generate e-invoices, though they can voluntarily adopt the system. The threshold has been progressively reduced since e-invoicing launched for businesses above ₹500 crore in 2020.
Can I file GSTR-1 and GSTR-3B myself without a CA?
Yes. Both GSTR-1 and GSTR-3B can be filed directly on the GST portal by an authorised signatory of the business. For businesses with straightforward transactions (limited invoice types, no complex ITC situations), self-filing is practical. You may still want a CA for the annual return (GSTR-9) or if you face officer queries or audits.
What is PMT-06 and when do I pay it?
PMT-06 is the challan used by QRMP taxpayers to make their monthly tax payment for the first two months of each quarter. You pay the estimated tax liability by the 25th of the following month. The third month’s liability is settled through the GSTR-3B filing. Underpayment attracts interest at 18% per annum, so estimate conservatively.
How do I use IFF for my B2B invoices under QRMP?
Log into the GST portal, navigate to “Services” then “Returns” then “Invoice Furnishing Facility”. You can upload B2B invoice details for months 1 and 2 of the quarter by the 13th of the following month. IFF is optional but strongly recommended if your buyers need to claim ITC in those months rather than waiting for your quarterly GSTR-1.
What should I do if my GSTR-2B shows ITC I cannot claim?
If GSTR-2B shows ITC from a supplier you cannot identify, or ITC on purchases that are blocked under Section 17(5) of the CGST Act, do not claim it. Claiming ineligible ITC is a compliance risk. Contact your supplier to verify the invoice details if needed, and only include ITC in GSTR-3B that you are eligible for and can reconcile to an actual purchase.
