Firms and companies add their deed or incorporation certificate.
What is the GST state code for Assam?+
18. Every GSTIN issued to a business registered in Assam, including one in Diphu, starts with 18, followed by the PAN of the business.
How can I get a GST number in Diphu?+
Share your PAN, Aadhaar, photo, address proof and bank details with us on WhatsApp. We file Form GST REG-01 online, you confirm an Aadhaar OTP, and the department issues your 15-digit GSTIN starting with 18 and the registration certificate (REG-06), usually within 3 to 7 working days.
Does GST apply in the Karbi Anglong Autonomous Council area?+
Yes. GST applies in Sixth Schedule areas of Assam exactly as elsewhere, including Karbi Anglong district. The income tax exemption that some Scheduled Tribe residents of North-Eastern areas get under section 10(26) of the Income-tax Act does not extend to GST. Registration limits and the process are the same.
What if my GST application from Diphu gets a query or is rejected?+
We reply to the officer's query (Form REG-03) with the right clarification or documents within 7 working days. If an application is still rejected, we fix the cause and refile at no extra professional fee.

The GST portal assigns your registration either to the Commissionerate of Taxes, Assam (State GST) or to the Central GST administration, based on your address. The jurisdiction is printed on your certificate; the process is the same and fully online.
Can farmers in Diphu get GST registration?+
Farmers selling only their own produce don't need it. Registration is useful if you also run a shop, agri-input dealership, mill, cold storage, transport or processing unit, or sell to big buyers who want GST invoices.
Do small tea growers in Karbi Anglong need GST registration?+
A grower selling green leaf from their own garden is an agriculturist and generally doesn't need GST registration for that sale. A grower who also processes, packs or trades tea, or runs a bought-leaf factory, needs registration once over the limit.
Can a small business in Diphu choose the composition scheme?+
Yes. In Assam, traders and manufacturers with turnover up to ₹1.5 crore can opt for composition and pay 1% of turnover (5% for restaurants), and service providers up to ₹50 lakh pay 6%. You can't collect GST from customers or sell goods to other States under composition.
Do I need a separate GST registration for a branch in another district of Assam?+
No. One GST registration covers the whole State. A shop, godown or office in another district of Assam is added as an additional place of business. You need a separate registration only in another State.
Do contractors working for government departments in Karbi Anglong need GST?+
Yes. Government departments and agencies ask for a GSTIN in tenders and work orders, and deduct TDS under GST on larger contracts. The TDS shows in your GST account and is used to pay your tax.
Do I need a trade licence along with GST in Diphu?+
GST doesn't need one, but your local body may: the Guwahati Municipal Corporation, municipal boards and town committees issue trade licences in towns, and gaon panchayats may levy a trade licence fee in rural areas. A trade licence is also useful supporting proof of your business.
