ASI/ASISSE Notice Return Filing Services in Mumbai
Expert Consultants for Companies, LLPs & Industrial Establishments in Mumbai — MoSPI / NSO Compliance
You opened this page because you received a notice. Maybe it landed in your inbox last week. Maybe your accounts team in your Mumbai office flagged it this morning. Either way, the first reaction for most businesses is the same — "Is this real, or is someone trying to scam us?"
It's real. Completely.
Since April 2026, the National Statistical Office has been sending out notices to thousands of factories, private limited companies, LLPs, and public sector units across India — including a significant number of enterprises headquartered or registered in Mumbai, Maharashtra. These notices ask businesses to log into a government portal and submit detailed financial and operational data for FY 2024–25. They come from MoSPI (Ministry of Statistics and Programme Implementation), and they carry the force of the Collection of Statistics Act, 2008 behind them.
Non-compliance isn't a slap on the wrist. For companies, penalties start at Rupees 5,000 — and then add another Rupees 5,000 for every single day you continue to default. That clock starts ticking 14 days after the initial notice.
ASC Group has been helping companies, LLPs, and industrial establishments across Mumbai respond to these notices — correctly, completely, and on time. If you've just received one and don't know where to start, read on.
Why Mumbai Businesses Are Seeing These Notices
Mumbai is India's financial and commercial capital. It houses the highest concentration of incorporated services sector enterprises in the country — from listed companies and financial services firms to IT companies, logistics hubs, and export-oriented manufacturers. That concentration means Mumbai-based GSTINs appear heavily in NSO's sampling frame.
Under ASISSE, the selection unit is not the company as a whole. NSO selects at the State-level GSTIN level using the GSTN database. So if your business has a Maharashtra GSTIN — whether your registered office is in Nariman Point, BKC, Andheri, Thane, or Navi Mumbai — and that GSTIN was in the selected sample of approximately 1,21,350 enterprises nationally, you've received the notice.
For ASI filers specifically, Maharashtra's large industrial base — chemicals, pharmaceuticals, engineering, food processing — means factories registered under the Factories Act from Mumbai, Thane, and Raigad districts regularly appear in ASI samples.
ASI and ASISSE — What's the Difference?
Two separate surveys. Two different sets of businesses. One shared legal framework.
ASI (Annual Survey of Industries) has been running since 1959. It targets the registered manufacturing sector: factories under the Factories Act, 1948, bidi and cigar establishments, electricity undertakings, and industrial units broadly. If your Mumbai or Thane factory has been filing under the Factories Act, your establishment may well have appeared in an ASI sample before, even if your finance team never dealt with it directly.
ASISSE (Annual Survey of Incorporated Services Sector Enterprises) launched in April 2026 — the first time India has attempted a structured, annual survey of the formal services sector. It covers Private Limited Companies, Public Limited Companies, LLPs, and PSUs in services: IT and ITES, trade, transport, hospitality, education, healthcare, finance, insurance, real estate, and professional services. Given Mumbai's dominance in financial services, BFSI, and IT — ASISSE is particularly relevant here.
Both surveys run under the Collection of Statistics Act, 2008 (as amended in 2017) and the Jan Vishwas (Amendment of Provisions) Act, 2023.
One thing to be clear about — these surveys have absolutely nothing to do with your Income Tax or GST assessments. The Act legally bars NSO from sharing your submitted data with the Income Tax Department, GST authorities, SEBI, or RBI for enforcement purposes. The data goes into computing national economic indicators. That's it.
What Happens If You Ignore the Notice?
| Default Stage | Penalty |
|---|---|
| Failure or refusal to furnish information | Up to Rupees 5,000 (companies) / Rupees 1,000 (individuals) |
| Non-compliance continuing beyond 14 days | Up to Rupees 5,000 per day (companies) / Rupees 1,000 per day (individuals) |
| Wilful submission of false information | Imprisonment up to 6 months and/or fine |
| Recovery mechanism | As arrears of land revenue under Section 15C |
The part that catches most businesses off guard: paying the penalty doesn't mean you don't have to file anymore. The return is still mandatory — the penalty is on top of, not instead of, the filing requirement.
How ASC Group Handles the Filing for Mumbai Clients
Notice Verification First Before anything else, we confirm the notice is legitimate, verify the GSTIN(s) selected, check the reference period, and map out your exact filing obligation. Mumbai businesses with multiple GSTINs across Maharashtra need particular attention here — each selected GSTIN must be filed independently.
Block-by-Block Data Preparation The questionnaire covers specific data blocks — enterprise identity (Block 1), fixed assets (Block 3), working capital (Block 4), employment headcount (Block 5), input consumption coded via CPC 3.0 (Blocks 6A & 6B), revenue and output data (Block 7A), and digital technology usage (Blocks 11 & 12). Every figure gets traced back to your source financials.
Reconciliation We reconcile your GST turnover, P&L, balance sheet, payroll register, and fixed asset schedule — making sure everything aligns before submission. A mismatch caught here saves you from NSO queries later.
Multi-GSTIN Apportionment Many Mumbai-headquartered companies run consolidated books covering multiple states. We break down data to the specific GSTIN level — apportioning turnover, employees, and assets accurately.
Portal Submission and Post-Filing Support We handle the actual filing through the official MoSPI secure portal, run portal validation checks, and remain available for any follow-up queries from NSO field officers.
Documents You'll Need
- Audited Balance Sheet and P&L for FY 2024–25
- Trial balance
- GST returns and GSTIN-wise turnover breakdowns
- Payroll register — headcount split by gender
- Fixed asset schedule with depreciation
- Working capital and loan statements
- Production records and raw material consumption data (ASI filers)
- Electricity and fuel cost data
- Factory licence (ASI filers)
- NIC 2025 classification of your main business activity
Mumbai-Specific Local Section
Industries We Frequently Support in Mumbai:
- BFSI companies — banks, NBFCs, insurance firms, asset management companies
- IT and ITES companies in BKC, Powai, Malad, and Andheri
- Pharmaceutical and chemical manufacturers in Thane, Navi Mumbai, and Raigad
- Logistics and warehousing businesses at JNPT corridor
- Export-oriented manufacturing units
- Hospitality and real estate companies
- Professional services firms — consulting, legal, advisory
Our Mumbai Clients Typically Face These Specific Challenges: Large BFSI and IT companies often have consolidated books across 15–20 states. Separating Maharashtra GSTIN-level data from group financials requires careful apportionment — and it's work that can't be rushed. We've done this for clients ranging from mid-size NBFCs to listed IT companies, and the process is well-established at our end.
Frequently Asked Questions
Is the notice I received in Mumbai genuine? Yes. ASISSE was officially launched via a PIB Press Release dated 6 April 2026 (Release ID: 2249336). Verify independently: the portal URL should be on the mospi.gov.in domain, and the Field Office contact in your notice should match NSO's published directory.
My Mumbai company has GST registrations in 8 states. Do I file for all of them? Only for the GSTINs for which you've received a notice. If NSO selected multiple GSTINs separately, each needs its own independent return. Data cannot be consolidated across GSTINs.
Will the data I submit affect my GST or Income Tax position in Mumbai? No. The Collection of Statistics Act, 2008 legally bars NSO from sharing submitted data with any tax authority — Income Tax, GST, SEBI, or RBI — for enforcement use.
What if our audit for FY 2024–25 isn't finalised yet? We can work with provisional accounts, but the earlier you engage us, the more comfortable the timeline. Deadlines are fixed, and penalties accrue daily once they start.
Can ASC Group handle clients across Mumbai — including Thane and Navi Mumbai? Yes. We serve clients across Greater Mumbai, Thane, Navi Mumbai, and the broader MMR.
Don't Let the Deadline Slip
Penalties under the Collection of Statistics Act don't wait. And the filing itself — particularly for large Mumbai corporates with multi-state operations — requires detailed financial reconciliation that can't be done overnight.
