Employing Company Directors

When you employ a company director — whether that's yourself or someone else — PAYE and National Insurance operate differently from standard employees. Directors' National Insurance is calculated on their total annual earnings rather than what they're paid in each individual pay period. This matters whether you run a large company or are a sole director operating your own limited company.

Directors are employees for tax purposes

All company directors count as employees for tax and National Insurance purposes. This applies even if you're the only director of your own company and don't have any other staff.

Directors pay employee National Insurance on their annual salary and bonuses above £12,570. The company must also pay employer's National Insurance on directors' salaries — you cannot avoid this even if you're both the director and the company owner running your own payroll.

Dividends are treated differently and have separate tax rules.

How National Insurance works for directors

The key difference for directors is that their National Insurance contributions are worked out based on annual earnings, not the amount paid in each individual pay period.

This is important because directors are often paid irregularly — they might take a small salary monthly and then pay themselves bonuses at year-end based on company performance. Calculating National Insurance annually prevents directors from being unfairly charged more than they should pay.

Two calculation methods

When running payroll for directors, you can use one of two methods to calculate National Insurance. Your payroll software should support both approaches, and you may be able to switch methods during the tax year depending on your software.

Standard annual earnings period method

This method suits directors who are paid irregularly.

Each time you pay the director, calculate their National Insurance on their total pay for the tax year so far (including any bonuses). Then subtract the total employee National Insurance already paid this year to work out what they now owe.

This means the National Insurance deduction adjusts automatically based on cumulative earnings to date.

Alternative method

This method works well for directors paid regularly throughout the year.

Each time you pay the director, calculate their National Insurance only on that period's pay (including any bonuses for that period). At the end of the tax year, use your payroll software to calculate whether additional employee National Insurance is due and deduct it from their final payment.

This approach spreads contributions more evenly through the year but requires a final reconciliation.

When and how to pay

Although National Insurance for directors is calculated annually, you still pay it to HMRC on your usual payroll schedule — whether that's weekly, monthly, or quarterly.

Report directors' pay and deductions through your Full Payment Submission (FPS) as you would for other employees. You must include:

• Either 'AN' (for the standard annual earnings period method) or 'AL' (for the alternative method) in the 'Director's NIC calculation method' field
• The 'Week of director's appointment' field completed

Use payroll software to work out the National Insurance due under whichever method you've chosen.

Category letter changes

A director's National Insurance category letter may change during the year — for example, if they reach State Pension age. When this happens, the director might be due a National Insurance refund.

Use your payroll software to recalculate their National Insurance. You can do this either when the category letter changes or at the end of the tax year.

When a director leaves or changes role

If someone stops being a director, you need to notify HMRC by deleting the 'Director's NIC calculation method' entry in your Full Payment Submission after you've paid them for the last time.

Use payroll software to calculate any outstanding National Insurance and deduct what the director owes from their final payment.

If the director remains as an employee

When a director steps down but continues working for the company as a standard employee, continue calculating their National Insurance based on their total earnings for the whole tax year as if they were still a director.

From the next tax year onwards, calculate their National Insurance as you would for any other employee — based on each individual pay period rather than annually.

Running payroll for directors

If you're a director running your own company's payroll, you must follow these rules even when you're the only person on the payroll. You'll need payroll software that can handle directors' National Insurance calculations.

The same reporting requirements apply: you must submit Full Payment Submissions to HMRC showing your pay, deductions, and the director-specific information outlined above.
