GSTIN vs PAN

GSTIN and PAN are India' two primary tax identifiers — one for direct tax (income tax), one for indirect tax (GST). Every GSTIN actually contains the PAN of the business embedded in it.

🧾

GSTIN

Goods and Services Tax Identification Number — required for businesses with taxable turnover above ₹20L (services) or ₹40L (goods). 15-character identifier issued state-wise.

🪪

PAN

Permanent Account Number — required by every individual, company or entity in India for income tax filing, investments, and financial transactions above ₹50,000.

🏆 Verdict

Both are needed for any GST-registered business — PAN is always required first, GSTIN is obtained using the PAN. For individuals below GST threshold: PAN is required, GSTIN is not. To check: your GSTIN characters 3–12 should match your PAN exactly.

Frequently Asked Questions

Is GSTIN derived from PAN?

Yes. GSTIN = 2-digit state code + 10-digit PAN + 1-digit entity number + 1 check letter + Z check character. Characters 3–12 of any GSTIN are always the PAN of that entity.

Can I verify a PAN from GSTIN?

Yes — extract characters 3 to 12 from the GSTIN. This is the taxpayer's PAN. Use our free GSTIN validator and PAN validator to cross-check both.

What if my GSTIN PAN does not match?

This indicates either a typo in the GSTIN or a fraudulent number. A mismatch means ITC claims against that invoice can be rejected.
