Telephones - mobile

This guide explains your tax and National Insurance contributions (NICs) obligations if you cover the cost of an employee’s mobile phone.

Please note that the rules in this guide don’t apply to a device such as an iPhone or BlackBerry – the range of functions these devices offer means that HM Revenue & Customs (HMRC) doesn’t consider them to be primarily mobile phones. For details of the rules that apply, see the A to Z entry ‘Assets made available to an employee’.

On this page:

You provide an employee with one mobile phone

Definitions or restrictions

Employee’s own mobile – you pay the supplier directly

Definitions or restrictions

You cover the costs of an employee’s mobile phone by paying the phone company directly. The contract for the phone is between the employee and the mobile phone company.

What to report, what to pay

For employees earning less than a rate of £8,500 per year, unless the exception outlined below applies:

  • report on form P9D – section A(2)
  • add the value of the benefit to the employee’s other earnings when deducting and paying Class 1 NICs (but not PAYE tax) through your payroll

For company directors or employees earning at a rate of £8,500 or more per year, unless the exception outlined below applies:

  • report on form P11D - section B
  • add the value of the benefit to the employee’s other earnings when deducting and paying Class 1 NICs (but not PAYE tax) through your payroll

Work out the value to use

For employees earning less than a rate of £8,500 per year:

  • if you pay no more than the employee’s monthly tariff, then the value to use for both P9D and Class 1 NICs purposes is the full amount you pay to the phone company
  • if you pay any private call charges that aren’t covered by the employee’s monthly tariff, then this amount should also be included for P9D and Class 1 NICs purposes
  • if you pay any business call charges that aren’t covered by the employee’s monthly tariff, then you can disregard them for Class 1 NICs purposes but you should report them on form P9D unless you have a dispensation covering these amounts

For company directors or employees earning at a rate of £8,500 or more per year:

  • if you pay no more than the employee’s monthly tariff, then the value to use for both P11D and Class 1 NICs purposes is the full amount you pay to the phone company
  • if you pay any private call charges that aren’t covered by the employee’s monthly tariff, then this amount should also be included for P11D and Class 1 NICs purposes
  • if you pay any business call charges that aren’t covered by the employee’s monthly tariff, then you can disregard them for Class 1 NICs purposes but you should report them on form P11D unless you have a dispensation covering these amounts

Exceptions

If the employee’s phone is acquired for business purposes and is only used for business calls, then the following rules apply.

For employees earning less than a rate of £8,500 per year, you have:

  • no reporting requirements
  • no tax or NICs to pay

For company directors or employees earning at a rate of £8,500 or more per year:

  • report on form P11D - section N – unless you have a dispensation for this item
  • you have no tax or NICs to pay

Employee’s own mobile – you reimburse the employee

Definitions or restrictions

You cover the costs of an employee’s mobile telephone by reimbursing the employee. The contract for the phone is between the employee and the phone company.

What to report, what to pay

Reimbursements of an employee’s monthly mobile phone tariff count as earnings, so:

  • add them to the employee’s other earnings
  • deduct and pay PAYE tax and Class 1 NICs using your usual payroll procedures

If you reimburse call charges in excess of those included in the employee’s monthly tariff, then:

  • for amounts relating to private calls, you must add them to the employee’s other earnings and deduct and pay PAYE tax and Class 1 NICs through your payroll, as above
  • for amounts relating to business calls, you have no tax or NICs to pay but for company directors and employees earning at a rate of £8,500 or more per year you must report on form P11D – section N – unless you have a dispensation covering these amounts

How a dispensation can reduce your expenses and benefits reporting

Work out the value to use

The value to put through your payroll is any amount of the employee’s monthly tariff you reimburse plus the cost of any additional private calls you reimburse.

The value to report on form P11D is the cost of any business calls you reimburse that aren’t covered by the monthly tariff.

Employee’s ‘pay as you go’ mobile – you pay for business calls

Definitions or restrictions

You reimburse the costs of identifiable business calls on an employee’s ‘pay as you go’ mobile phone, or you provide the employee with a ‘top up’ to be used only for business calls.

What to report, what to pay

For employees earning less than a rate of £8,500 per year, you have:

  • no reporting requirements
  • no tax or NICs to pay

For company directors or employees earning at a rate of £8,500 or more per year:

  • report on form P11D – section N – unless you have a dispensation covering this item
  • you have no tax or NICs to pay

Work out the value to use

The value to use is the amount you reimburse or the amount of the top up you provide to the employee.

Where to report – understanding the £8,500 threshold

It’s important to choose correctly between forms P11D and P9D for each employee. The form to use depends on the whether the employee is a director of your company and on whether their earnings are above or below an annual rate of £8,500.
