Some employers provided employees with mobile phones for work twenty or so years ago. Those who did provided their employees with a Benefit in Kind (BIK). At that time, the BIK was £200.

What happens today?

Today, when claiming a phone bill on tax, an employer can provide each staff member with one mobile phone for business use with no associated BIK. If you run your own company, it can do this for you, too. Therefore, contractors can do this through their company regarding a mobile phone.

Mobile phone expenses 

When you’re a contractor or small company owner and use your mobile for work reasons, you can claim your mobile phone costs. However, you should ensure the personal element is only minor. If you’re starting your own business for the first time or have even been trading for a while and your mobile phone contract is up for renewal, you may get your new one in the name of your limited company.

When deciding on a mobile phone deal for your company, you should aim to choose the best package. You can do this when you research mobile phone contracts for small businesses. When you search, you should consider the terms of the monthly tariff. As part of this, you can ensure it fits your predicted business call requirements. Also, as most mobile phone contracts are for 24 months, you must consider this too when purchasing a new one.

Business landline and broadband 

Consider a claim for phone and broadband costs if you have a dedicated business telephone line and broadband. Can you claim the business line rental and broadband costs through your company? You can claim phone expenses and your contractor business broadband cost.

This is because you’ll incur the cost of your personal mobile or landline phone whether you use it for work reasons or not.

Furthermore, splitting out the cost of work-related calls can be difficult when you claim phone expenses. This is because companies now package phone costs with free minutes, etc. Therefore, if you’re unable to separate work calls from personal phone bills, you can’t claim them. This is due to the duality of purpose rules. To explain further, business calls incur no extra cost because of the tariff you pay for your phone calls.
