We register businesses anywhere in West Bengal. A business with places of business in more than one state needs one registration per state, and separate registrations are allowed for separate places of business inside West Bengal.
Everything you need for a GSTIN in Kolkata.
Who administers GST for a Kolkata business
GST registration is filed in Form REG-01 on the common portal and there is no West Bengal application form. West Bengal's own tax administration is the Directorate of Commercial Taxes, at comtax.wb.gov.in, and that is the office you deal with on state matters once the GSTIN is live. Your registration is allotted to either a Central or a State authority, and we tell you which one appears on your REG-06 certificate. We do not publish a commissionerate name for Kolkata, because the central list we would need to confirm it against is not currently reachable, and a wrong office name on a notice reply costs you time.
The registration thresholds in Kolkata are the ordinary ones: ₹40 lakh for goods and ₹20 lakh for services. West Bengal is not a special category state for the threshold, so there is no lower Bengal figure, whatever a competitor page tells you. Registration is compulsory regardless of turnover if you supply goods inter-state or sell through an e-commerce operator.
What a Kolkata GSTIN costs you beyond the GSTIN
Professional tax. West Bengal levies professional tax under the West Bengal State Tax on Professions, Trades, Callings and Employments Act, 1979, administered by the Directorate of Commercial Taxes. Two things exist here that Delhi does not have at all: PTEC, the enrolment your business takes in its own right, and PTRC, the registration you need as an employer deducting from salaries. Neither certificate carries a government fee. A duplicate certificate costs ₹20 per application under rule 26. The constitutional ceiling on professional tax is ₹2,500 per person per year under Article 276(2). We do not quote a West Bengal slab on this page: a revised schedule has been reported and the commentary sources cite different notifications, so we confirm your figure from the Directorate before you pay anything.
Shop and Establishment. A Kolkata shop or office registers under the West Bengal Shops and Establishments Act, 1963, through wbshopsonline.gov.in. The registration fee runs on a slab by number of employees, which we confirm for your headcount rather than publish. The useful West Bengal fact almost no competitor carries: renewal fees were dispensed with by notification Labr/175/IT&EoDB dated 7 January 2019, so renewal is deemed and free. You register once and you are not paying a renewal every year, unlike most states.
The municipal document, by its right name. Kolkata Municipal Corporation does not issue a "trade licence". It issues a Certificate of Enlistment, and if you ask for a trade licence at a KMC borough office that is the document you will be handed. The trade-category schedule sits in the Licence Department Budget Schedule that the Corporation passes each financial year under section 131(3) of the KMC Act, 1980, so the rate depends on your trade category and premises and changes with the budget. Renewal is annual and late renewal attracts a fine. We do not publish a KMC amount, because the KMC rate chart runs to more than two hundred trade categories with an area element and we could not verify a figure you would be billed against.
What else a Kolkata business usually needs
If you are incorporating alongside the GST registration, note that Kolkata is now ROC Kolkata-I, which covers Kolkata district (and Sikkim), while the rest of West Bengal including Howrah is ROC Kolkata-II. Both offices sit in Kolkata city, so the address of the ROC is not the guide; the district of your registered office is. See our company registration in Kolkata guide for that filing, and LLP registration in Kolkata if you are forming an LLP instead. Most Kolkata registrants also want the Certificate of Enlistment and Shop and Establishment registration done in the same run, and West Bengal's state single-window portal for approvals and clearances is Silpasathi at silpasathi.wb.gov.in.

What we'll need from you.
We pre-check every scan before filing.
Common GST registration mistakes in Kolkata.
These six issues account for most of the queries we see on West Bengal applications. We screen for all six before filing.
Address that doesn't match PAN
A business address different from the PAN-registered one is the top rejection cause. We reconcile both before filing.
Wrong entity type
Filing as a proprietor when you're a partnership (or vice-versa) means a cancellation and re-registration. We confirm the correct type first.
Unrealistic turnover estimate
Over- or under-stating turnover invites scrutiny and mismatches later filings. We base the figure on real projections.
Incomplete document set
Missing or late scans stall the application. Our checklist ensures everything goes in together, the first time.
Ignoring post-registration compliance
A GSTIN with no returns filed gets suspended. We hand over a due-date calendar and file your first GSTR-1 & 3B.
Missing composition-scheme eligibility
Small B2C businesses under ₹1.5 crore often qualify for the simpler Composition scheme. We check before defaulting to Regular.
