Have you ever noticed how most of your big bills—like cloud services, HR tools, or digital marketing—are in your Head Office’s name? Now think about this: your branches in other states are the ones actually using those services. But when GST credit is claimed, it’s a mess.
If this sounds like your business, you might be losing lakhs of rupees in GST input tax credit (ITC) every year. And when the tax officer knocks on your door for a GST audit, it’s not going to be a pleasant surprise.
Here’s Where It Goes Wrong
Let’s break it down. Your Head Office in Mumbai gets a Rs.10 lakh invoice from AWS. The cloud services are used across teams in Bengaluru, Pune, Chennai, and Delhi. But the bill stays with the Mumbai HO. No one shares the credit with the other branches. There’s no ISD mechanism, and no cross-charging either.
Result? The input tax credit is stuck. It can’t be claimed by the branches. And when you still try to claim it, your GST returns don’t match, and the system throws up errors. This is exactly what GST auditors look for—and it can lead to notices, penalties, or disallowed credit.
So What’s the Right Way to Do It?
Thankfully, the GST law in India already has two ways to deal with this. You just need to pick one and follow it properly.
Option 1: Use the ISD Method
If your Head Office is receiving the invoices for services that your branches use, then registering as an Input Service Distributor (ISD) is the cleanest way to go. The HO collects all invoices, and then distributes the eligible GST credit to branches through ISD invoices.
So if your Chennai branch uses 20% of AWS, it gets 20% of the ITC—simple and sorted. This method is especially useful for businesses that centralise service purchases like software, consulting, or digital ads.
Option 2: Go for Cross-Charging
If you don’t want to go the ISD route, then there’s cross-charging. In this method, the Head Office bills the branches for their share of the services used. The branch gets the invoice, pays GST, and claims credit like they would with any other vendor invoice.
This method works well if you already have systems in place for inter-branch transactions. But remember—it needs proper documentation and fair valuation of internal services.
What About Intra-State HO and ISD?
Here’s something many people miss. If your HO and ISD are in the same state, it’s not fully clear whether GST applies to ISD transactions. The rules are still evolving. Until then, the best approach is to stay consistent with your method and maintain proper records to justify your ITC claims.
GST Audits Are Getting Smarter
Tax officers aren’t just looking at forms anymore. They’re using technology to compare your invoices, returns, and supplier details. If your GSTR-2A doesn’t match GSTR-3B, or if credit is claimed in the wrong state, they’ll know.
Sadly, many finance teams don’t focus on credit structuring—they only focus on filing returns. And that’s where lakhs of rupees get lost, quietly, every month.
What You Should Do Now
If your HO is receiving all the service invoices, but your branches are using them, it’s time to take action. Don’t delay this.
Check how your GST credit is being handled today. Are you using ISD? Are you cross-charging? Or are you missing both? Once you know, work with your CA or GST advisor to get it right.
Set up processes. Train your team. Keep documentation ready. Because claiming credit properly not only saves money—it protects you during audits.
