Mobile phones for directors

For many owner‑managed companies, the director’s mobile phone is both a business tool and something they use every day. Done correctly, a company‑provided phone can be highly tax‑efficient. Done incorrectly, it can create an unnecessary benefit‑in‑kind charge.

Here’s how the rules broadly work and what to think about as a director.

One mobile phone per director can be tax‑free

HMRC allows an employer (including your own limited company) to provide one mobile phone per employee without creating a taxable benefit, as long as certain conditions are met. This can include directors.

If the phone contract is in the company’s name and the company pays the bills directly, then:

• The director should not be taxed on the cost of that phone or its line rental, and

• The company can usually deduct the cost as a business expense.

This remains the case even if there is some private use, provided the phone is genuinely provided for business reasons and the arrangement is within HMRC’s normal guidance.

Contracts in a personal name are treated differently

Problems often arise when the phone contract is in the director’s personal name, but they want the company to pay or reimburse the costs.

In many cases:

• Reimbursing a director’s personalmobile contract can be treated as a taxable benefit or additional salary.

• This may create extra Income Tax and National Insurance for the director and Class 1 or Class 1A NIC for the company.

There can be limited scope to claim a business use portion of a personal bill, but it tends to be messy, relies on detailed analysis of itemised bills and may not be worth the admin for smaller amounts.

This is why, where appropriate, it is often cleaner and more efficient to have the contract in the company’s name from the outset.

What about multiple phones or devices?

The tax exemption is usually understood as applying to one phone per employee. If a company provides multiple phones to the same director (for example, a personal phone and a separate “business” phone where both are used privately), the extra devices can fall outside the exemption.

Similarly, tablets or data‑only devices may not be covered in the same way as a traditional mobile phone, depending on the exact setup and use.

If you’re considering multiple devices, it’s worth getting advice first so you understand:

• Which items are likely to be fully exempt, and

• Which might create taxable benefits.

Practical approach for director‑shareholders

For many small companies, a straightforward approach works best:

• Put one mobile phone contract in the company’s name.

• Use that phone for both business and reasonable private use.

• Keep personal contracts separate if you want extra devices for purely private reasons.

This keeps the tax position simple and usually avoids benefit‑in‑kind issues, while still allowing the director to have a fully functional phone for work and everyday use.

We also recommend clearly documenting:

• That the phone is provided by the company,

• That it’s intended primarily for business purposes, and

• That it falls within the company’s normal policies for staff/directors.

How we help directors decide

Every director’s circumstances are slightly different. We help by:

• Reviewing your current phone arrangements and explaining the tax position.

• Advising whether moving a contract into the company’s name makes sense.

• Highlighting any benefit‑in‑kind risks where the company is paying personal bills.

• Ensuring costs are recorded and claimed correctly in your accounts.

If you’re unsure whether your mobile phone is set up in the most tax‑efficient way, we can review the details and give clear, practical recommendations before your next contract renewal.
