Bihar GST Registration

Online GST registration is the process of enrolling a business on the GST Network (GSTN) portal at gst.gov.in to obtain a 15-digit Goods and Services Tax Identification Number (GSTIN). It is required because only a registered taxpayer can legally collect GST from customers, claim input tax credit (ITC) on purchases, file GST returns, and issue tax-compliant invoices. Operating a taxable business without registration is an offence under the CGST Act and attracts significant penalties.

GST registration is mandatory for any business or individual whose aggregate annual turnover exceeds ₹40 lakh for goods or ₹20 lakh for services in most states (₹20 lakh for goods and ₹10 lakh for services in special-category states such as those in the North-East and hill states). Registration is also compulsory regardless of turnover for e-commerce sellers on any marketplace, businesses making interstate supplies of goods or services, importers and exporters, Input Service Distributors, casual taxable persons, non-resident taxable persons, and those liable to pay tax under the Reverse Charge Mechanism.

The online GST registration process has two parts. In Part A, visit gst.gov.in, select "New Registration," enter your PAN, mobile number, and email address, verify them with the OTPs received, and note the Temporary Reference Number (TRN) generated. In Part B, log in using the TRN within 15 days, fill in your business details (trade name, business type, principal place of business, additional places of business, HSN or SAC codes), upload the required documents, complete Aadhaar authentication, and submit. On submission, an Application Reference Number (ARN) is issued immediately, confirming your application is pending review. As of April 2025, multi-factor authentication (MFA) via an authenticator app is mandatory for every GST portal login.

The documents required vary slightly by business type but typically include: PAN card of the proprietor, partners, or directors; Aadhaar card of the authorised signatory; a passport-size photograph; proof of the principal place of business (electricity bill, property tax receipt for owned premises, or rent agreement with the landlord's NOC and utility bill for rented premises); and a cancelled cheque or bank account statement. Private limited companies and LLPs must additionally provide the certificate of incorporation, the memorandum and articles of association or LLP agreement, and a board resolution or letter of authorisation for the signatory. Partnership firms need the partnership deed.

The Government of India charges no fee for GST registration — applying directly on the GST portal at gst.gov.in is completely free. If you engage a CA, tax consultant, or online service provider for assistance with documentation, form-filling, and follow-up, their professional charges typically range from ₹500 to ₹3,500 depending on the complexity of the business structure. There is no hidden government charge at any stage of the process.

Standard GST registration is approved within 7 working days when documents are complete and Aadhaar authentication is successful. Under the fast-track scheme introduced in November 2025, low-risk applicants — typically small businesses with a monthly outward tax liability up to ₹2.5 lakh — can receive their GSTIN within 3 working days through Aadhaar-based authentication alone. If the GST officer raises a query via Form GST REG-03, you must respond with the requested documents within 7 working days or your application may be rejected, though you can reapply immediately.

Aadhaar authentication is a mandatory step in the GST registration process where your Aadhaar number is verified against the UIDAI database. During the application, an OTP is sent to the mobile number linked with your Aadhaar; entering this OTP confirms your identity. If Aadhaar authentication is not completed or fails, the application is routed to the physical verification route, where a GST officer visits your principal place of business within 15 days to verify the premises and submit a report before the ARN is generated — significantly extending the timeline.

As per the GSTN advisory dated 12 February 2025, certain applicants identified through a risk-assessment mechanism are required to complete biometric verification in addition to standard Aadhaar OTP authentication. These applicants receive an intimation and must visit a designated GST Suvidha Kendra within 15 days to provide fingerprints and a photograph. The Application Reference Number (ARN) is generated only after biometric verification is successfully completed. Not all applicants are selected — it is risk-based — but ignoring the intimation will stall your registration entirely.

You are not required to provide bank account details at the time of submitting the GST registration application itself, but as per the GSTN advisory effective 20 November 2025, valid bank account details must be added and verified within 30 days of receiving your GSTIN, or before filing your first GSTR-1 or Invoice Furnishing Facility (IFF), whichever is earlier. Failure to add a verified bank account within this window may result in automatic suspension of your GSTIN, preventing you from filing returns until the account is added.

Yes, you can complete GST registration entirely on your own through the GST portal at gst.gov.in — no CA or professional is legally required. The process is designed for self-service and most sole proprietors and small business owners with all documents ready can complete Part A and Part B in under an hour. Professional help is advisable if your business has a complex structure (multiple partners, company with foreign directors, SEZ unit), if your Aadhaar is not linked to an active mobile number, or if the GST officer raises a query that needs careful response to avoid rejection.

A GSTIN (Goods and Services Tax Identification Number) is a unique 15-digit alphanumeric code assigned to every registered taxpayer in India. The first two digits represent the state code (for example, 07 for Delhi, 09 for Uttar Pradesh, 29 for Karnataka, 33 for Tamil Nadu, 36 for Telangana). The next ten digits are the taxpayer's PAN. The 13th digit is the entity number indicating the count of registrations under the same PAN in that state. The 14th digit is currently a default "Z," and the 15th is a checksum character. A business with operations in multiple states receives a separate GSTIN for each state.

Yes, voluntary GST registration is permitted for any business or individual regardless of turnover. Reasons to register voluntarily include claiming input tax credit on business purchases, issuing GST-compliant tax invoices to corporate or government clients who require a valid GSTIN, onboarding as a seller on any e-commerce marketplace, qualifying for government tenders and the Government e-Marketplace (GeM), and establishing financial credibility for bank loan applications. Once voluntarily registered, all GST compliance obligations — including return filing — become mandatory.

Freelancers and self-employed professionals must register for GST once their annual income from services exceeds ₹20 lakh (₹10 lakh in special-category states). If a freelancer provides services to clients outside their home state, or exports services to overseas clients, registration is mandatory regardless of turnover — interstate supply of services requires compulsory registration, and export of services is zero-rated under GST, meaning a registration is required to claim refunds of GST paid on business inputs. Many freelancers below the threshold register voluntarily to access ITC and meet client requirements.

Yes, GST registration is state-specific. A business must obtain a separate GSTIN for each state or union territory where it has a branch, warehouse, office, or makes taxable supplies. A single PAN-based entity can hold multiple GSTINs — one per state. Within a single state, a business may optionally obtain separate registrations for different business verticals. The GST 2.0 portal update has simplified applying for additional state registrations: existing registered taxpayers no longer need a unique combination of PAN, mobile, and email for each new state application — they can reuse their existing credentials.

Operating a business that is legally required to be registered under GST without obtaining registration attracts a penalty of ₹10,000 or 10% of the tax amount due, whichever is higher. In cases of deliberate tax evasion, the penalty rises to 100% of the tax evaded. Interest at 18% per annum also accrues on all unpaid tax from the date it was originally due. The GSTN's AI-powered cross-checking of PAN, bank transactions, and e-invoice data has significantly increased the detection of unregistered liable businesses in 2025, making voluntary early registration the safest course of action.

You can track your GST registration application status on the GST portal without logging in. Go to gst.gov.in, click on "Services" → "Registration" → "Track Application Status," and enter your ARN (Application Reference Number). The portal displays whether your application is pending for processing, pending for clarification (REG-03 query raised), pending for order, or approved. Once approved, the GSTIN and registration certificate (Form GST REG-06) can be downloaded directly from the portal under the "My Profile" section after logging in.

After GST registration, a regular taxpayer must file GSTR-1 (outward supplies) either monthly or quarterly depending on turnover, and GSTR-3B (summary return and tax payment) on the same frequency. An annual return in Form GSTR-9 is due by 31 December each year. From July 2025, GSTR-3B is hard-locked after filing — corrections to sales figures can only be made through GSTR-1A before the 3B due date. Composition scheme taxpayers file the quarterly CMP-08 statement and an annual GSTR-4. Nil returns must still be filed for months with no business activity; failure to file returns for 6 consecutive months can lead to GST registration cancellation.

Yes, GST registration can be cancelled online by filing Form GST REG-16 on the portal. Before the cancellation is processed, all pending returns must be filed up to the date of cancellation, all outstanding tax dues must be cleared, and ITC claimed on remaining closing stock must be reversed by paying an equivalent amount. The GST officer then issues a cancellation order in Form GST REG-19. After cancellation, a final return in Form GSTR-10 must be filed within three months of the cancellation date — failing to file GSTR-10 attracts a late fee and can result in further legal proceedings.
