How the code appears in a GSTIN

A GSTIN is a 15-character number. The first two digits are the state code — so every GSTIN issued in Bihar begins with 10. The next ten characters are the PAN, followed by an entity code, a default digit and a checksum.

GST jurisdiction in Bihar

  • Every taxpayer in Bihar is assigned to either a Central or State GST jurisdiction (division, range and commissionerate)
  • You can find your jurisdiction on your GST registration certificate (REG-06) or by searching your GSTIN on the GST portal
  • Intra-state supplies in Bihar attract CGST + SGST; inter-state supplies attract IGST

Staying compliant in Bihar

Beyond this, every business operating in Bihar needs to keep its core registrations and filings up to date:

  • GST registration and returns (the Bihar state code is 10)
  • Shop & Establishment registration for the premises and staff
  • Professional tax deduction and payment (levied in Bihar)
  • Income-tax filing, TDS and proper bookkeeping

Why This Matters

Staying compliant with Indian regulations protects your business from penalties, interest and unnecessary legal trouble. It is always wise to maintain proper records and documentation so that any future scrutiny can be handled smoothly. Rules and thresholds in state wise guides are revised periodically, so it helps to review your obligations at the start of each financial year. Professional guidance from a qualified CA, CS or advocate ensures that filings are accurate and submitted well before the due date.

Small businesses and startups especially benefit from setting up a simple compliance calendar to track recurring deadlines. Government portals now allow most applications and filings to be completed online, reducing paperwork and turnaround time. Keeping your PAN, registration certificates and board resolutions organised makes every subsequent filing faster. When in doubt, it is better to seek clarification early rather than risk a notice or a late-filing penalty later.

A clear understanding of the applicable law helps you make confident, well-informed business decisions. TaxClue's experts regularly assist businesses across India with end-to-end state wise guides support at transparent, affordable pricing. Timely compliance also improves your credibility with banks, investors and government authorities. Reviewing your obligations with a professional at least once a year keeps your business audit-ready and stress-free.
