Verify a supplier's GSTIN with GST Search Taxpayer
Verified by: Manual review by the editorial team · Next review due: 21 Apr 2027
Check that a GSTIN on an invoice is live, matches the legal name and is filing returns, so your input tax credit is safe.
Why check
Under India’s GST, a buyer’s input tax credit (ITC) can be denied if the supplier’s registration is not live or returns are not filed. Invoices sometimes carry cancelled or wrong GSTINs. Check new suppliers before ordering and existing ones periodically.
GSTIN format
15 characters, e.g. 27AAACM1234A1Z5: state code (2), PAN (10), entity number (1), “Z” (1), check digit (1). The state code should match where the supplier sits.
Steps
- Open GST – Search Taxpayer. No login needed.
- Enter the GSTIN and the captcha.
- Compare Legal Name of Business (and Trade Name) with the invoice.
- Confirm GSTIN/UIN Status is Active.
- Check Taxpayer Type: “Composition” suppliers cannot pass on ITC.
- Open “Show Filing Table” and confirm GSTR-1 and GSTR-3B are filed up to recent months.
- Save a dated screenshot in your vendor master.
Suggested internal rule
Verify before the first order, re-verify key suppliers quarterly, and reconcile ITC against GSTR-2B. GST law and rate notifications are on the CBIC site.
Questions on this topic
取引先がGST登録しているかどうか確認できますか？
GSTポータルの納税者検索で、GSTINから登録名、登録状況、登録州、申告の提出状況などを確認できます。仕入先が申告を行っていないと自社の仕入税額控除に影響するため、継続取引の前に確認するのがおすすめです。
インドの取引先の信用調査はどうすればよいですか？
まずMCAのマスターデータで、会社の登記状況、設立日、資本金、取締役、担保設定、直近の届出状況を確認します。あわせてGSTポータルで登録状況と申告の提出状況を確認すると、実在性と活動状況の目安になります。重要な取引では、信用調査会社のレポートや現地訪問も組み合わせてください。
