The services Sriperumbudur's plants buy every day

GST by type of contract
How the four common plant contracts are taxed
Rates and options differ sharply between these services, and plants check them. This is the position as it stands in November 2026.
- Manpower supply
18% on the whole bill
GST applies to wages, PF, ESI and your service charge together. Security guards supplied by a firm that isn't a company go under reverse charge.
- Canteen inside the factory
5%, credit barred on provisions
A contractor running the canteen charges 5% and can't claim credit on provisions or gas. Since 1 November 2026, catering bought from another caterer gives limited credit. The plant gets credit only where the law requires it to run a canteen.
- Staff bus with driver and fuel
5% or 18%, your choice
At 5%, credit is limited to hire from other operators. At 18%, full credit. From 1 November 2026, unless a non-company operator charges 18%, the company hiring the bus pays 5% under reverse charge.
- Job work on the plant's material
Mostly 18% since September 2025
Engineering job work moved from 12% to 18% on 22 September 2025. Some listed goods keep lower rates, so we check your entry.

Process

Common mistakes
GST problems that hold up payments for Sriperumbudur vendors
When a plant stops paying, the cause is nearly always on the invoice or in the return. These are the ones we see most often.
Invoice issued without an IRN
A vendor's turnover crossed ₹5 crore, but invoices still go out without e-invoicing, so the plant can't treat them as valid.
How National Filings prevents it
We set up e-invoicing, check which past invoices need correcting and agree a fix with the buyer.
IRN missed the 30-day window
A larger vendor raises an invoice late in the month and tries to report it to the IRP more than 30 days after its date.
How National Filings prevents it
We track invoice dates and report them promptly. Where the window is missed, we work out the correct way to bill again.
Wrong GSTIN for the plant
The invoice carries the plant's head office GSTIN instead of the unit at Sriperumbudur, so it lands in the wrong GSTR-2B.
How National Filings prevents it
We keep a list of each buyer GSTIN by location and check every invoice against the purchase order.
Bus hire billed at the wrong rate
A proprietor operator adds 5% to the bill while the company also pays reverse charge, or each assumes the other is paying.
How National Filings prevents it
We settle 5% or 18% with you and the plant in writing, and bill accordingly from the start.

GST checks a plant vendor can't skip

FAQ
GST in Sriperumbudur: what plant vendors ask
Is your office in Sriperumbudur?
No. Our only office is in Karaima Nagar, Kundrathur, open Monday to Saturday, 9 am to 7 pm. Sriperumbudur clients usually work with us entirely over WhatsApp and email, and can visit Kundrathur whenever they want to meet.
When do I have to start e-invoicing?
Once your aggregate turnover has gone above ₹5 crore in any financial year since 2017-18. From then on, every invoice to a registered buyer needs an IRN from the Invoice Registration Portal. An invoice without one isn't valid, and plants will reject it.
Is there a time limit for generating an IRN?
Yes, for larger businesses. Since 1 April 2025, taxpayers with turnover of ₹10 crore or more must report invoices and credit or debit notes to the IRP within 30 days of their date. After that the portal won't accept them, so invoices need reporting promptly.
Why does a plant hold my payment over GSTR-2B?
The plant can claim input credit only on invoices that appear in its GSTR-2B, and that depends on your GSTR-1. If your invoice is missing, late or under the wrong GSTIN, the plant loses its credit, so it holds your payment until the invoice shows up.
What GST do I charge on manpower supply?
18% on the full invoice value, including wages, PF and ESI, not only your service charge. Security services are different: if the supplier isn't a company, the registered buyer pays GST under reverse charge.
What rate applies to a canteen I run inside a factory?
A canteen contractor generally charges 5% and can't claim credit on provisions, gas or equipment. From 1 November 2026 the one exception is catering bought from another caterer, with credit capped at the 5% level. Older advance rulings disagreed, so we read your contract before confirming. The factory can claim credit only where the law requires it to provide the canteen.
Should I bill staff bus hire at 5% or 18%?
Both are allowed for hire of buses with driver and fuel. At 5% your credit is limited to hiring from other operators, and at 18% you get full credit. From 1 November 2026, if you are not a company and your customer is one, the customer pays 5% under reverse charge unless you charge 18% on your invoice, in which case you pay it. We'll help you agree the option with the plant.
