How to calculate employee NI deductions
Different to employer NI contributions, where there is only one rate and one threshold, employee NI deductions take into account two different thresholds and contribution rates, a higher one and a lower one.
This has the effect that – for most NI category letters – deductions for every additional 1£ earned above the higher threshold of £50,268 per year increases deductions only c. 1/4 as much as income below that level, benefiting high earners.
Employee NI deduction rates
Calculating employee NI deductions is following a simple formula. Employees pay 0% on income below their monthly allowance and a certain rate on income that falls between the two thresholds and above the upper threshold. Starting from 6 January 2024 the following NI contributions rates for employee deductions are effective.
| | Threshold 1 (£1,048 to £4,189) | |

National Insurance is also payable on any employee benefits or expenses. Employers must report and pay this particular NI liability at the end of the tax year. You must pay NI on benefits such as work phones, accommodation, and bonuses. Note that every expense and benefit is calculated differently, so you need to check on what you’re required to report and pay.

You have to complete a P11D form for every employee that you have given benefits or expenses to and return it to HMRC. It is possible to deduct and pay class 1A NI through your payroll as long as you remember to register with HMRC before the beginning of the tax year.
Directors of Limited Companies
Company directors also need to pay NI contributions on any income over £9,880 as they are also considered employees . NI liability is calculated from annual earnings but is paid in accordance with your applicable payroll schedule. Even if you’re the only employee of your company and you’re the director, your company will still need to pay NI on your salary.
2023 & The Social Care and Health Levy
Employers need to make sure that their payroll software will automatically take into account the new Social Care and Health Levy, which will be introduced in April 2023. For this, you need to include the levy as a separate item in payslips. Employees that are over the State Pension age will also pay the levy.
You also have to pay to employer NI contributions?
Besides deduction NICs from employee pay, employers also contribute NICs on top. The following table shows a summary of the contributions and thresholds and you can use this employer NI contributions calculator to understand how much NIC you need to pay.
| Income Threshold (from 6 August 2022) | Employer NI on Earnings up to threshold | Employer NI on Earnings above threshold |

Final Thoughts
The National Insurance hike, though costly, is straightforward, once you figure it out. However, one thing you want to avoid with the income thresholds changing in April and again in July 2022, is adjusting your payroll manually. Your payroll software should take care of these changes seamlessly and communicate those to your employees on their payslips. Finally, you can look into the different methods of reducing your NI bill which could benefit both you and your employees.
