Starting a Business in Sikkim: Choosing a Structure and Local Registrations

What founders starting in Sikkim should know beyond incorporation: the ROC, state registrations, industrial approvals, and the local startup ecosystem.

Choosing a structure and incorporating works the same way across India. But starting a business in Sikkim also means dealing with state registrations and local authorities, and knowing the local startup ecosystem. This guide covers the local side.

Incorporation and the ROC

Companies and LLPs with a registered office in Sikkim are registered with the Registrar of Companies with jurisdiction over Sikkim, which the MCA website lists. The registered office can be a home, a co-working space, or an office, with the right address proof.

State Registrations

  • Professional Tax: Sikkim levies professional tax on salaries and on businesses, administered by the state Commercial Taxes or Taxation Department. The company needs an enrolment certificate for its own liability, and a registration certificate once it deducts professional tax from employees' salaries. Check the current slabs with the department, as they're revised from time to time.
  • Shops and Establishments: Sikkim's shops and establishments rules apply to commercial establishments in the state. Register with the Labour Department.
  • Trade licence: A trade licence is usually needed from the Department of Commerce and Industries or the local municipal body. Sikkim has its own rules on who may hold a trade licence, so check eligibility early if the founders aren't from the state.
  • GST: registration once turnover crosses the threshold, or immediately in compulsory cases. In Sikkim, the threshold is ₹20 lakh for both goods and services.

Industrial and Manufacturing Units

Manufacturing and industrial units need further approvals — building permissions, fire safety, pollution control consents, factory licences, and power connections. In Sikkim, the state's single-window clearance system brings many of these together. Industrial land is often allotted through the state Commerce and Industries Department.

The Startup Ecosystem

Startups in Sikkim are concentrated around Gangtok. Local support includes:

  • The state's support for local entrepreneurs.
  • North East Venture Fund: a fund set up with SIDBI that invests in startups from the north-eastern states.

Startups can also apply for DPIIT recognition nationally, and explore the state's policies for startups and innovation.

Choosing a Structure

The choice of structure doesn't depend on the state, but local factors can matter: state incentives may be tied to the entity that applies for them, and land allotments may restrict transfers, so it's best to set up the long-term entity before applying for either.

A Checklist for Founders in Sikkim

  1. Choose the structure based on funding plans and risk.
  2. Incorporate with the ROC, or set up the proprietorship's registrations.
  3. Register for Professional Tax and, where it applies, Shops and Establishments.
  4. Get a trade licence for your premises.
  5. For manufacturing, apply for approvals through the state's single-window clearance system.
  6. Explore local incubators and startup programmes.
