GST Registration for Government Tenders: Is It Mandatory & How It Works

GST is central to almost every government tender — from eligibility to invoicing to pricing. Here's exactly what you need to know about GST registration and how it affects your bids.

Is GST Registration Mandatory to Bid?

In most cases, yes. Government tenders routinely require:

• A valid GSTIN (GST Registration Number) as an eligibility document
• GST registration to raise tax invoices for supplies
• GST compliance status to be active and valid

That said, how GST is treated in the price varies by tender. Some tenders on GeM and other platforms have GST-exclusive vs inclusive pricing options.

When GST Registration Is Required (Under the GST Act)

• Mandatory for turnover above the threshold (₹40 lakh goods / ₹20 lakh services, lower for special category states)
• Mandatory for inter-state supply of goods/services
• Required by specific tenders regardless of your turnover (they set it as a condition)

Even if your turnover is below the threshold, a tender can mandate GSTIN — register voluntarily if you want those contracts.

How to Get GST Registration

1. Visit the GST portal — gst.gov.in
2. Prepare documents: PAN, Aadhaar, bank account, business proof, photograph, address documents
3. Submit the GST REG-01 application online
4. Verify with Aadhaar OTP / e-Sign for faster approval
5. Receive your GSTIN and registration certificate

Registration is free; compliance requires timely GSTR-1, GSTR-3B, and annual returns.

GST Rates by Category

The GST rate applied to your tender depends on the goods/service:

Always confirm the applicable HSN/SAC and rate for your items — wrong GST on the BOQ misprices your bid.

How GST Affects Your Bid Price

Two ways GST shows up in a tender:

1. Inclusive price — your quoted rate includes GST; the buyer deducts at evaluation or pays you the total
2. Exclusive price — GST is added on top at the applicable rate; your base rate should exclude GST

Input Tax Credit (ITC): as a registered supplier you can claim ITC on your purchases. This means GST on inputs isn't a cash cost — but it does affect your working capital. Price carefully so you don't lose the ITC timing benefit.

GST Invoicing for Government Supplies

• Raise tax invoices with correct GSTIN, HSN/SAC, rate, and amounts
• e-Invoicing is mandatory above the turnover threshold (₹5+ crore)
• Government buyers may require bilaterally agreed invoices on specific formats
• Keep GSTR-1 reflecting all government supplies (sales to govt are also reportable)

A mismatch between your invoice and the e-Procurement/GeM order delays payment.

Common GST Mistakes in Tenders

• Quoting inclusive of GST when the buyer expects exclusive (or vice versa)
• Using the wrong HSN/SAC code
• Unregistered status when the tender mandates GSTIN
• Not claiming ITC properly in your margin
• Invoicing with mismatched GSTN vs the registered bidder entity
