The NI184 is a statutory report that details the both the the employer’s and employee’s contributions to the National Insurance Scheme (NIS). Although it is generated by TTPay automatically, there are three main factors that can contribute to inaccurate contributions shown in the NI184. We will discuss these common issues and provide a solution.
1. An employee was set to a statutory override, but the contributions have not been adjusted

A statutory override is a worksheet setting that lets the user bypass the system’s automatic calculations and manually enter statutory adjustments. A common mistake users make is by adjusting the employee’s contribution, but not the employer’s. This results in an inaccurate representation of the true NIS contributions on the NI184.
Solution: Ensure that both the employer’s/employee’s contributions (highlighted in black on the worksheet) is accurate. Also, always generate a NIS Deductions Report (found in >) before creating a NI184. This highlights any abnormalities in the employer’s and employee’s contribution.
2. Employee’s working period doesn’t include a Monday

On the worksheet, each employee has a date range that determines the number of weeks worked. This range is what the NI184 uses to categorize contributions into the appropriate week.
If an employee has left or entered the pay cycle early, the user must ensure that a Monday falls within their date range. Without this, the NI184 cannot correctly categorize the contributions to the appropriate week.
Solution: Edit the employee’s work period on the worksheet to ensure that a Monday is included in their start or end date.
3. ‘Exclude NIS’ or ‘Class Z’ settings were enabled accidentally

TTPay automatically sets an employee to Class Z if they are aged over 65 or under 16. However, apart from the Statutory Override, there are still ways NIS can be excluded manually:
- By enabling the Exclude NIS box under Statutory Options in the employee’s window, or
- Manually setting the employee to Class Z in the employee’s window or the worksheet.
Solution:
Print the NIS Deductions Report. This will highlight which employees are marked as Class Z, allowing the user to confirm whether each one should actually be Class Z or not.
General Recommendation
We recommend that you print a NIS Deductions report, which can be found (). This highlights any abnormalities in the employer’s and employee’s contribution. If you are unsure on the rate of contributions, check the National Insurance Board’s page to view the current statutory rates.
