Bihar-specific notes
- Professional Tax applies — Bihar Tax on Professions, Trades, Callings and Employments Act, 2011.
- Excise revenue is zero (prohibition state since 2016) — significant impact on state finances vs other states.
- Standard ₹40 lakh GST goods threshold applies (not a special-category state).

How HelloBooks does this
HelloBooks handles Bihar compliance end-to-end — GSTIN validation against state code 10, automatic CGST + SGST split on intra-state supplies, Professional Tax deductions on payroll, and direct GSTR filing.
- 1
Configure your Bihar GST profile
Add your Bihar GSTIN (state code 10), trade name, and PAN in Settings → Taxes. HelloBooks validates the state code and the embedded PAN automatically. Mark your registration type (Regular, Composition, SEZ, Casual, Non-Resident, Input Service Distributor).
- 2
Add Bihar place of supply on every transaction
Tag the place of supply on every invoice and bill. When the customer's place of supply is Bihar (and your registration is also Bihar), HelloBooks charges CGST + SGST in equal halves of the rate. Inter-state supplies trigger IGST.
- 3
Configure Bihar Professional Tax on payroll
For employees based in Bihar, HelloBooks computes the Professional Tax deduction from the current slab table. Annual cap is ₹2500. Verify the live slab on the Bihar Commercial Taxes Department portal before each state-budget cycle.
- 4
File monthly / quarterly GST returns from the books
HelloBooks aggregates your Bihar invoices, credit notes, and amendments into GSTR-1 (outward supplies) and the GSTR-3B liability summary. Review, then file directly via the GST portal or export the JSON.
- 5
Reconcile GSTR-2B against your purchase register
Each month, the GST portal publishes GSTR-2B — auto-drafted from your suppliers' GSTR-1 filings. HelloBooks reconciles this against your purchase register and flags missing input tax credit before the ITC claim window closes.
Frequently asked questions
What is the Bihar GST state code?
10. Every GSTIN issued in Bihar starts with 10, followed by the entity's 10-character PAN and three further characters. HelloBooks validates the structure and the embedded state code whenever you save a customer or vendor master.
What is the GST registration threshold in Bihar?
₹40 lakh for goods (₹20 lakh for services) — standard national thresholds. Inter-state suppliers, e-commerce operators, casual taxable persons, and persons under reverse charge must register from the first rupee — no threshold applies.
Does Bihar levy Professional Tax?
Bihar levies Professional Tax under Article 276 of the Constitution. Annual cap is ₹2500 (the constitutional maximum is ₹2,500/year). Slab tables are revised in state budgets — verify the current schedule on the Bihar Commercial Taxes Department portal.
Bihar is a State — does that change my GST compliance?
Bihar levies SGST alongside CGST on intra-state supplies (each half of the rate). Inter-state supplies attract IGST. Returns and filing process are identical across states.
Where do I file Bihar GST returns?
All GST returns are filed through the central GST portal (gst.gov.in) — there is no state-specific filing portal. The Bihar Commercial Taxes Department (https://www.biharcommercialtax.gov.in/) handles state-level matters: registration assistance, advance rulings, and Professional Tax / state-specific cesses.
