Trinidad NIS contribution rates 2026

The National Insurance System (NIS) is a social security program administered by the National Insurance Board of Trinidad and Tobago (NIBTT). It provides insured workers with coverage for short-term benefits (sickness, maternity, injury), long-term benefits (invalidity, old age pension, survivors), and employment injury benefits.

All employers who hire workers in Trinidad & Tobago are legally required to register with NIBTT and to make monthly contribution payments on behalf of their employees. Contributions are shared between the employer and the employee — the employer pays two-thirds and the employee pays one-third of the total contribution.

NIBTT organizes insured persons into sixteen earnings classes (Class I through Class XVI) based on their weekly earnings. Each class specifies a fixed employer contribution amount and a fixed employee contribution amount. The total contribution rate is 16.2% of the assumed average weekly earnings for each class.

For employees paid on a monthly basis, weekly earnings are calculated by dividing the monthly salary by 4.333 (the average number of weeks per month). The result is compared against the class thresholds to determine which class applies.

The Employeecolumn shows the amount deducted from the employee’s wages each week. The Employercolumn shows the additional amount the employer contributes on top of that. The employer always pays twice the employee’s share. The Total is the combined weekly contribution remitted to NIBTT per employee.

For monthly payroll, multiply each weekly amount by 4.333 to get the approximate monthly figure. For example, an employee in Class VI would result in an employee deduction of approximately $240.05 per month ($55.40 × 4.333) and an employer contribution of approximately $480.08 ($110.80 × 4.333).

When you add an employee to Enzure and enter their salary, the system converts it to a weekly equivalent, determines the correct earnings class from all sixteen classes, and stores the applicable rates. When you generate forms for a pay period, these figures populate the NI184 and NI187 automatically — no manual table lookup required.

When NIBTT publishes updated contribution tables, Enzure is updated to reflect the new rates. Any form generated after the update will use the current figures automatically.
