## Two different methods of calculating director NIC

There are the two ways to calculate National Insurance for company directors, and it is up to the employer to decide which one to use.

**Standard method**: NIC liabilities are calculated on an*annual*basis based on the*cumulative*earnings in the tax year in relation to the*annual*earnings thresholds, using the*blended*NI rate**Alternative method**: NIC liabilities are calculated on a*monthly*basis based on*monthly*earnings in a given month in relation to the*monthly*earnings thresholds and the NI rate*effective*in the period.

In both cases, NICs are calculated using the formula:

**Employer NIC** = (**Income>ST**) × **13.8%**

**Employee NIC** = (**UEL>Income>PT**) × **11.5%** + (**Income>UEL**) × **2%**

## The standard method

In the standard method, sometimes also called the cumulative method, NIC liabilities are calculated on an annual basis based on the *cumulative* earnings in the tax year in relation to the *annual* earnings thresholds taxed at the *blended* NI rate.

This means that NI contributions become due only after total earnings surpass the relevant annual thresholds. As a result, NICs are lower in the beginning of the year, and higher in later periods.

### Employee NICs

Employee contributions are 11.5% on earnings between the Primary Threshold and the Upper Earnings Limit and 2% on earnings above the Upper Earnings Limit:

NI category | Primary Threshold | PTRate | Upper Earnings Limit | UELRate |

all categories | £12,570 | 11.5% | £50,270 | 2.0% |

### Employer NICs

Employer contributions are 13.8% on earnings above the Secondary Threshold, which differs by NI category:

NI category | Secondary Threshold | STRate |

A, B, C, J (most employees) | £9,100 | 13.8% |

F, I, L, S (Freeport workers) | £25,000 | 13.8% |

H, M, V, Z (apprentices and veterans) | £50,270 | 13.8% |

## The alternative method

The alternative method, sometimes also called the employee method, is almost identical to how non-director employees are treated, namely the annual tax-free allowance is spread equally across the year and NICs are paid on any amounts in that month surpass the relevant monthly thresholds, subject to the NI rate effective for the pay period.

The only difference is that at the end of the tax year, a balance payment is made to ensure that the total amount paid under the alternative method is the same that would have been paid under the cumulative method.

### Employee NICs

Employee contributions are 10/12%* on earnings between the Primary Threshold and the Upper Earnings Limit and 2% on earnings above the Upper Earnings Limit:

NI category | Primary Threshold | PTRate | Upper Earnings Limit | UELRate |

all categories (start of year) | £12,570 | 12.0% | £50,270 | 2.0% |

all categories (6 Jan onwards) | £12,570 | 10.0% | £50,270 | 2.0% |

### Employer NICs

Employer contributions are 13.8% on earnings above the Secondary Threshold, which differs by NI category:

NI category | Secondary Threshold | STRate |

A, B, C, J (most employees) | £758 | 13.8% |

F, I, L, S (Freeport workers) | £2,083 | 13.8% |

H, M, V, Z (apprentices and veterans) | £4,189 | 13.8% |

## Which method should you choose?

The regular method is best suited for company directors who are paid irregularly and/or are set to receive considerable bonuses during the tax year.

Directors should opt for the alternative method when they regularly receive a regular salary. This is because they may prefer to keep their net pay the same in every pay period.

The alternative method should be avoided when being paid irregularly. Since the employee method uses the monthly thresholds in all pay periods but the last one, which uses the annual threshold, it may happen that a director’s earnings were higher than the UEL (which is taxed at a lower rate) in some periods but not in others. This may result in directors paying more NICs than what they are actually being paid for the period.

## Examples

### Standard method

John has an income of £60,000 and he was nominated director on the 24th June 2021. The tax year starts on the 6th April 2023. He chooses the cumulative (i.e. regular) method. For the first two months, he does not pay any NI as his total income at the end of month 2 (i.e. May) is £10,000.

- In June he pays (£15,000 – £12,570)*10% = £291.60
- From July to January he pays £600.00
- For example in July he pays -> (£20,000 – £12,570)*12% – £291.60 = £600.00
- In February the total compensation exceeds also the UEL, then he pays: (£55,000 – £50,270)*2% + (50,270 – £12,570) *12% – £4,571.04 = £127.00
- In March the total compensation also exceeds the UEL, then he pays: (£60,000 – £50,270)*2% + (50,270 – £12,570) *12% – £4,698.04 = £100.00

It follows that John’s total NICs amount to £4,718.60 for the tax year. You can apply the same logic to get the employer’s NICs, which in this case amount to £7,024.20 for the tax year. Remember that when calculating the employer’s NI, you need to take into account only the Secondary Threshold.

**Director table method**

If John had started working for the company on the 6th July 2023, the thresholds would have been pro rated according to the number of weeks he would have spent as a director in the tax year. The ST would have been £9,100 * (39 weeks)/(52 weeks) = £6,825 while the PT and UEL would have been £9,427.5 and £37,702.50, respectively. It follows that John’s NICs would have amounted to £3,598.53, while the company would have paid £5,268.15.

### Alternative method

Let’s suppose that John chooses to use the normal employee method. He will pay NI as a normal employee, with a balance payment at the end of the tax year (i.e. March 2024)

- By February 2023, John will have paid £4,324.54 in NI
- In March 2023, the NI payment will be: (£60,000 – £50,270)*2% + (50,270 -£12,570) *12% – £4,324.54 = £394.06

The amount John pays under the normal employee method is £4,798.04, while the company ends up paying £7,024.20. We can see that John and the company pay the same under the two different schemes.
