Claiming GST Input Tax Credit on PCB Fabrication

Engineers comparing quotes often compare a tax-inclusive price against a tax-exclusive one without noticing. If your business is registered under GST, the tax on a domestic PCB order is generally recoverable — which changes the comparison materially.

The basic mechanism

GST is designed so that tax is paid on value added, not on the full price at every stage. A registered business pays GST on its inputs, charges GST on its outputs, and pays the government the difference. The tax on your inputs is input tax credit.

So for a registered buyer, GST on a PCB order is usually a timing difference rather than an expense: cash out now, offset against your output liability later.

What makes it claimable

• You are registered, and the purchase is for business use. Boards for a product you are developing qualify; boards for a personal hobby project do not.
• You hold a valid tax invoice showing your GSTIN, the supplier’s GSTIN, the HSN code, the taxable value and the tax split.
• The supplier has actually filed the invoice, so it appears in your GSTR-2B. This is the condition most people are caught by — your credit depends on someone else’s compliance.
• You have received the goods, and you pay the supplier within the period the law allows.

Why GSTR-2B is the part that bites

Holding an invoice is not enough. If a supplier does not report it, the credit never appears in your GSTR-2B and you cannot take it — leaving you chasing a vendor over a filing you have no control over.

Practical advice: check that a new supplier’s invoices actually show up in your 2B for the first month or two before placing larger orders. It is a five-minute check that tells you whether their compliance is real.

Domestic purchase versus import

On a domestic purchase you receive a tax invoice, the tax appears in your 2B, and you claim it in the ordinary way. Nothing unusual happens.

On an import, IGST is paid at the border on the assessable value plus customs duty. That IGST is generally creditable too, but the mechanics differ: your evidence is the bill of entry rather than a supplier invoice, and the cash leaves at clearance, before the goods reach you. Basic customs duty itself is not creditable — it is a cost, not a tax you recover.

So the two routes are not equivalent even when both are described as creditable. One blocks cash at the border and adds a non-recoverable duty; the other does neither.

Comparing quotes properly

If you are registered, compare tax-exclusive prices, and count only the non-recoverable parts as cost — customs duty, freight, clearance charges, and the value of the delay. If you are not registered, compare tax-inclusive prices, because the tax genuinely is a cost to you.

Getting this wrong in either direction is common, and it tends to flatter whichever quote was presented in the more favourable format.

Not tax advice

GST rules change, and how they apply depends on your registration, your state and what you are building. This is a general explanation, not advice for your situation — check with your chartered accountant before relying on it.
