National Insurance for Directors: How Is It Calculated in 2026/27?

National Insurance for Directors works differently from ordinary employee National Insurance because company directors are generally assessed using an annual earnings period. National Insurance for Directors can therefore produce different deductions during the year even where a director receives a regular monthly salary.

For 2026/27, National Insurance for Directors affects both the director and the company. Employee Class 1 NIC may be deducted from the director’s salary, while the company may also pay employer Class 1 NIC. National Insurance for Directors should therefore be considered when deciding salary levels, paying bonuses and comparing salary with dividends.

This guide explains National Insurance for Directors using the 2026/27 thresholds and rates. It covers the annual calculation, the alternative method, employer NIC, mid-year appointments, bonuses, Employment Allowance and practical examples.

What is National Insurance for company directors?

Directors are treated as employees for Class 1 NIC purposes. National Insurance for Directors can therefore involve an employee contribution and a separate employer contribution.

National Insurance for Directors normally applies to salary, directors’ fees and bonuses that count as earnings. Genuine dividends are not salary and are not normally subject to National Insurance for Directors.

National Insurance for Directors is operated through PAYE payroll. National Insurance for Directors should therefore be calculated and reported through payroll rather than through the director’s Self Assessment alone.

For company directors, National Insurance is calculated differently from that of ordinary employees because directors are generally assessed using an annual earnings period. This means the calculation considers earnings across the relevant tax year rather than relying only on weekly or monthly thresholds.

Both employee and employer Class 1 contributions may apply. Salary, directors’ fees and bonuses can count as earnings for contribution purposes, while genuine dividend payments are normally excluded. The company may also have an employer contribution liability even where the director does not personally pay employee contributions.

National Insurance for Directors: 2026/27 thresholds and rates

The annual Primary Threshold is £12,570. National Insurance for Directors at employee level is generally nil up to that threshold for a standard category A director. Between £12,570 and the Upper Earnings Limit of £50,270, National Insurance for Directors is generally charged at 8%.

National Insurance for Directors at employer level uses a different threshold. The Secondary Threshold is £5,000 and the standard employer rate is 15%.

The Lower Earnings Limit is £6,708. National Insurance for Directors can therefore support a National Insurance record at earnings levels where no employee NIC is actually deducted, subject to the individual’s circumstances.

These figures mean National Insurance for Directors can create an employer cost even when the director pays no employee NIC. HMRC confirms these 2026/27 thresholds and rates.

For the 2026/27 tax year, the annual Primary Threshold is £12,570. Directors earning above this amount generally pay employee Class 1 contributions at 8% on earnings up to the Upper Earnings Limit of £50,270. Earnings above £50,270 are generally charged at the lower employee rate of 2%.

Employer contributions operate from a lower threshold. The Secondary Threshold is £5,000 for 2026/27, with employer Class 1 contributions generally charged at 15% on earnings above this level. This means a company may face an employer contribution cost even when the director has no employee contribution deducted from their salary.

Why directors have an annual earnings period

National Insurance for Directors uses an annual earnings period because directors may have more control than ordinary employees over the timing of their remuneration.

Directors are generally assessed using an annual earnings period because they may have greater control over when and how they receive remuneration from their company. Using an annual basis helps ensure that contributions are calculated fairly across the whole tax year rather than being influenced by the timing of individual salary or bonus payments.

This approach can make directors’ payslips look different from those of ordinary employees, particularly where earnings vary during the year. The annual calculation considers cumulative pay and contributions already deducted, helping to produce the correct overall liability by the end of the tax year.

The annual basis means National Insurance for Directors ultimately looks at earnings across the director’s relevant annual earnings period.

National Insurance for Directors may therefore look unusual on payslips.

National Insurance for Directors is therefore a specific payroll calculation, not merely ordinary monthly employee NIC. HMRC confirms that directors’ contributions are generally worked out using annual earnings rather than simply treating every payment period independently.

National Insurance for Directors: Standard annual method

Under the standard annual method, National Insurance for Directors is calculated using total earnings paid in the tax year to date.

For example, if a director receives a modest monthly salary, National Insurance for Directors may remain at nil employee NIC until cumulative annual earnings pass the Primary Threshold. If a later bonus takes total earnings above the threshold, National Insurance for Directors is recalculated at that payment.

National Insurance for Directors automatically reflects salary, fees and bonuses included in cumulative earnings.

Under the standard annual method, contributions are calculated using the director’s total earnings from the beginning of the tax year up to the current pay period. Any contributions already deducted earlier in the year are taken into account before working out the amount due for the latest payment.

This method can result in little or no deduction during the earlier months where cumulative earnings remain below the relevant threshold. Once total earnings exceed the threshold, contributions may start to arise, with the calculation adjusting automatically as further salary, fees or bonuses are paid.

National Insurance for Directors using this method therefore remains cumulative throughout the year. HMRC describes the standard method as calculating the director’s liability using total pay for the tax year to date and taking account of contributions already deducted.

National Insurance for Directors: Alternative method

The alternative method can be used for National Insurance for Directors where directors are paid regularly.

However, National Insurance for Directors is still ultimately based on an annual earnings period. A year-end reconciliation is still required.

National Insurance for Directors under the alternative method therefore changes the timing of deductions rather than replacing the annual calculation.

National Insurance for Directors should also be reported correctly on the Full Payment Submission, using the relevant director calculation method indicator. HMRC states that this method is commonly used for directors receiving regular payments.

The alternative method can be used where a director receives regular payments throughout the tax year. Under this approach, contributions are calculated in a similar way to those of ordinary employees during each pay period, making monthly payroll deductions more consistent.

However, an annual reconciliation is still required at the end of the tax year. This ensures that the total amount paid matches what would have been due under the annual earnings basis and corrects any difference that may have built up during the year.

Example: salary of £12,570

Employee National Insurance for Directors is generally nil because the salary does not exceed the annual Primary Threshold.

Employer National Insurance for Directors is different because the Secondary Threshold is £5,000. At 15%, employer National Insurance for Directors is £1,135.50.

This example shows why a salary equal to £12,570 does not mean National Insurance for Directors is completely nil.

National Insurance for Directors should therefore be reviewed from both sides of payroll. Even where the director has no employee NIC deduction, the company may still have an employer National Insurance bill.

Example: salary of £50,270

Employee National Insurance for Directors is charged at 8% on earnings between £12,570 and £50,270.

Employer National Insurance for Directors is charged at 15% on earnings above £5,000. Employee NIC is £3,016 and employer NIC is £6,790.50.

National Insurance for Directors therefore creates a combined payroll burden that is significantly greater than the employee deduction alone.

If a director receives an annual salary of £12,570 in 2026/27, no employee Class 1 contribution is generally due because the salary does not exceed the annual Primary Threshold. However, the salary is still above the Secondary Threshold of £5,000, which means the company may have an employer contribution liability.

At the standard employer rate of 15%, the company would pay approximately £1,135.50 on the amount above £5,000, before considering any available Employment Allowance. This highlights why both the director’s personal deductions and the company’s payroll costs should be considered when setting a salary.

This is why National Insurance for Directors should be included in remuneration planning before a salary is fixed. A higher salary may generate Corporation Tax relief for the company, but National Insurance for Directors and Income Tax can reduce the overall benefit.

Example: salary of £60,000

At a salary of £60,000, National Insurance for Directors crosses the Upper Earnings Limit. The first £37,700 above the Primary Threshold produces £3,016 of employee NIC, leaving £9,730 above the Upper Earnings Limit.

National Insurance for Directors on that amount is charged at 2%, producing £194.60. Total employee National Insurance for Directors is therefore approximately £3,210.60.

Employer National Insurance for Directors is 15% on £55,000, the amount above the £5,000 Secondary Threshold.

The example shows that the employee rate falls to 2% above £50,270, but standard employer National Insurance for Directors continues at 15% above the Secondary Threshold.

If a director receives an annual salary of £50,270 in 2026/27, employee Class 1 contributions are generally charged at 8% on earnings between £12,570 and £50,270. This gives an employee contribution of approximately £3,016 for the year, assuming the standard category applies.

The company may also have to pay employer Class 1 contributions at 15% on earnings above the £5,000 Secondary Threshold. On a salary of £50,270, this would produce an employer liability of approximately £6,790.50 before taking account of any Employment Allowance that may be available.

Directors appointed part-way through a tax year

National Insurance for Directors needs additional care when a person becomes a director after the tax year has started. The earnings period is normally pro-rated using the weeks remaining from appointment.

This can reduce the thresholds used for National Insurance for Directors.

Where a person is already a director at the start of the tax year and later ceases to be a director, National Insurance for Directors normally continues to use the annual earnings period for that tax year.

National Insurance for Directors should therefore be set up with the correct appointment week in payroll. Correct setup is essential for National Insurance for Directors. HMRC states that a director appointed during the year generally has a pro-rata earnings period based on the weeks remaining in the tax year.

Bonuses and irregular director payments

Bonuses can cause a sudden increase in National Insurance for Directors.

Under the standard annual method, National Insurance for Directors is recalculated when the bonus is paid.

Under the alternative method, National Insurance for Directors may have been deducted periodically, but the annual reconciliation still brings total earnings into the final calculation.

It includes relevant salary, fees and bonuses, so timing a bonus into one month does not normally allow the director to escape the annual rules. Before a substantial bonus is approved, National Insurance for Directors, PAYE Income Tax and the company’s employer NIC cost should all be modelled.

Salary and dividends

National Insurance for Directors generally applies to salary but not to genuine dividends.

Salary can normally be deducted in calculating company profits where the normal tax rules are met, while dividends are paid from post-tax distributable profits. It can also help create qualifying earnings for the director’s National Insurance record, whereas dividends do not.

A lower salary may reduce it, but it can also reduce salary-related Corporation Tax relief or affect the director’s contribution record. A larger salary may increase National Insurance for Directors and Income Tax.

The best mix depends on company profits, other income, dividend tax, Employment Allowance and personal circumstances. National Insurance for Directors is an important factor, but it should not be treated as the only factor.

Lower Earnings Limit and the director’s NI record

The 2026/27 annual Lower Earnings Limit is £6,708. National Insurance for Directors can be relevant to the director’s contribution record even when earnings remain below the £12,570 Primary Threshold and no employee NIC is deducted.

This creates a range where it may support qualifying earnings without an employee contribution actually being taken from salary.

However, employer’s NI can still arise because the Secondary Threshold is only £5,000.

For this reason, this planning should distinguish between the Lower Earnings Limit, Primary Threshold and Secondary Threshold. Choosing a salary solely by looking at the employee threshold can overlook a real company cost.

Employer NIC and Employment Allowance

Employment Allowance can reduce eligible employers’ secondary Class 1 liabilities. For 2026/27, the allowance is up to £10,500, so it can significantly affect the cost of National Insurance for Directors where a company qualifies.

However, this in a single-director company often does not benefit from Employment Allowance where that director is the only employee liable for secondary Class 1 NIC. HMRC specifically excludes a limited company where there is only one director and that director is the only employee creating the relevant employer NIC liability.

It may have a different practical cost where another employee or director also satisfies the conditions.

This salary planning can change materially depending on Employment Allowance.

Directors reaching State Pension age

National Insurance for Directors can change when a director reaches State Pension age because this category may change. Employee NIC is generally no longer due under the relevant State Pension age category, although employer NIC can continue.

Because this uses annual rules, a category change may require payroll software to recalculate contributions. A refund of employee NIC can sometimes arise where the category changes during the tax year.

National Insurance for Directors should therefore not be processed by simply copying the previous month’s payroll settings.

HMRC advises employers to use payroll software to recalculate where a director’s category letter changes. It should be reviewed when the director approaches State Pension age so deductions and employer costs remain accurate.

Common calculation mistakes

A frequent error is calculating National Insurance for Directors exactly like ordinary monthly employee NIC without applying a director method. Another is failing to record the correct appointment week for a new director.

Companies also sometimes focus on employee deductions and forget employer NI. A salary at £12,570 can produce no employee NIC but still create employer NIC because the Secondary Threshold is £5,000.

Another mistake is assuming every company can use Employment Allowance to cover National Insurance for Directors. Single-director companies can be excluded under the rules.

Bonuses, fees, category changes and the year-end reconciliation can also be missed. National Insurance for Directors relies on accurate payroll setup, not simply payroll software itself.

The safest approach is to check director status, calculation method, appointment date, category letter and cumulative earnings before finalising payroll. National Insurance for Directors should also be reviewed before year-end remuneration decisions are made.

Does every director need a salary?

There is no general requirement for every director to take a salary. If no earnings are paid, National Insurance for Directors may not arise from that company.

However, taking no salary can have wider consequences. Its planning may involve considering whether a salary can support the director’s National Insurance record, use available allowances or generate an allowable company deduction.

A salary can also create employer this once it exceeds the Secondary Threshold, even if employee NIC is nil. The company must have sufficient cash to pay salary and payroll liabilities as they fall due.

For owner-directors, it should be considered alongside the company’s profit level, cash flow, Corporation Tax position and the director’s other income. A salary should be chosen for the overall tax and commercial result, not simply to minimise one payroll charge.

Reporting National Insurance through payroll

National Insurance for Directors is reported through PAYE using Real Time Information. The Full Payment Submission should identify the individual as a director and show the appropriate director NIC calculation method.

HMRC uses “AN” for the standard annual method and “AL” for the alternative method. National Insurance for Directors should therefore be configured correctly in payroll software from the outset.

Although It is based on annual earnings, amounts arising during payroll are still reported and paid through the company’s normal PAYE cycle. The annual basis does not mean the company waits until Self Assessment to deal with NIC.

Payroll should be reviewed when salary changes, bonuses are paid, a director joins or leaves, or a category changes. Accurate reporting makes National Insurance for Directors easier to reconcile and reduces the risk of unexpected PAYE liabilities.

Salary planning and total company cost

National Insurance for Directors can materially alter the true cost of a salary. A director may see only the employee NIC deducted from the payslip, but the company also has to fund employer NIC where applicable.

For example, increasing salary from £5,000 to £12,570 does not normally create employee National Insurance for Directors, but before Employment Allowance it can create £1,135.50 of employer NIC. The additional salary and employer NIC may, however, be deductible in calculating company profits where the normal Corporation Tax rules are satisfied.

National Insurance for Directors should therefore be modelled together with Corporation Tax, Income Tax and dividend tax. The cheapest salary from an NIC perspective is not automatically the most tax-efficient overall.

Where the director has another employment, pension, rental income or other taxable income, National Insurance for Directors is only one part of the wider calculation. Personal circumstances can change the optimum result.

Final thoughts

National Insurance for Directors is based on special annual earnings rules that distinguish directors from ordinary employees. For 2026/27, this generally uses a £12,570 Primary Threshold, a £50,270 Upper Earnings Limit and employee rates of 8% and 2%. Employer Ni is normally 15% on earnings above the £5,000 Secondary Threshold.

It can be operated using the standard annual method or the alternative method with a year-end reconciliation. National Insurance for Directors also needs additional attention where a director is appointed part-way through the year, receives a bonus, changes category or reaches State Pension age.

Employment Allowance can reduce employer costs for eligible companies, but not every director-only company qualifies. This should therefore be reviewed alongside salary, dividends, Corporation Tax, Income Tax and company cash flow.

Accurate payroll setup and year-end planning can prevent unexpected liabilities. This becomes much easier to manage when the annual method, employer cost and wider remuneration strategy are considered together.
