Every business operating formally in Sri Lanka needs to be registered and hold a Taxpayer Identification Number (TIN) before it can file returns, register for VAT, or open a proper business bank account. The process differs slightly depending on business structure, but the overall sequence is consistent.
Choosing a Business Structure
Most small and growing businesses register as a sole proprietorship, a partnership, or a private limited (Pvt Ltd) company. The right structure depends on liability exposure, ownership plans, and how the business intends to raise capital – a sole proprietorship is fastest to set up, while a Pvt Ltd company offers liability protection at the cost of more ongoing compliance.
Registering the Business
Sole proprietorships and partnerships register with the relevant local authority, while companies register with the Registrar of Companies. Once registered, the business receives its official registration documents, which are needed for the next step – obtaining a TIN.
Obtaining a TIN
A TIN is obtained through the Inland Revenue Department, using the business’s registration documents. This number is what identifies the business for every future filing – VAT registration, income tax returns, and any other statutory submission all reference the TIN.
- Confirm business structure before registering – changing it later means re-registering
- Keep registration documents on file; they’re required again for VAT registration and bank account opening
- Apply for a TIN as soon as registration is complete, rather than waiting until the first filing deadline
