Recent history and how to claim mobile phone as business expense 

If you work in IT, you may ask what can I claim as IT contractor tax deductions? What’s more, as part of a claim for phone and broadband costs, you may ask can I claim my mobile phone as a business expense? In fact, can I buy a mobile phone through my business too? Twenty or so years ago, some employers would choose to provide their employees with a mobile phone for work. Those that did also provided their employees with a Benefit in Kind (BIK). At that time, the BIK was £200. This was taxable on the employee through their PAYE tax code that was applied to their salary.

What happens today

Today, when it comes to claiming 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, when it comes to a mobile phone, contractors can also do this through their company. As a result, you can claim the charges for your business mobile phone expenses or SIM card tax-free, and there is no BIK.

As part of your small business mobile phone tax deduction, it’s advisable to get the bills in your company name. Therefore, you should ensure that your mobile phone contract is in the name of your contractor limited company. It’s also key to take note that although you may use your mobile phone for work and personal calls, you should ensure that any token personal use’ is ‘reasonable.’ Following this advice, you can claim phone expenses for your mobile usage and these are tax-deductible expenses.

Claim for phone and broadband costs -what can you claim?

Let’s now research what you can claim for your small business phone and broadband costs. 

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 decide to get your new mobile phone contract in the name of your limited company.

As part of deciding on a mobile phone deal for your company, you should aim to choose the best package. You can do this when you look into mobile phone contracts for small business. Basically, when you search, you should consider the terms of the monthly tariff. As part of this, you can ensure it fits with your predicted future needs for your business calls. Also, as most mobile phone contracts are for 24 months, you’ll need to consider this too when you take out a new mobile phone contract.

Business landline and broadband 

Let’s consider a claim for phone and broadband costs if you have a dedicated business telephone line and broadband. Basically, can you claim the business line rental and broadband costs through your company? The answer is you can claim phone expenses and your contractor business broadband cost. However, claiming for your business landline cost is on the basis that you’ll use your contractor business phone line for business calls only. In addition, the contract and bills for your dedicated business broadband and landline must be in the company name. As a result, you can claim the business phone costs and save tax on the landline for business use.

What’s more, if you work from home and have a dedicated phone line for work purposes, you may have your own home office. Two further things you can think about here in respect of tax relief when you work from home are:

A further thought is when you have a dedicated phone number for your company, it’ll look more professional. This is in terms of how it’ll look to your clients and contacts. Indeed, when shown on stationery such as business cards, letters, invoices, etc., it’ll remind them of your business.

Work-related only calls on personal phones 

When you claim phone and broadband costs, please bear in mind that business call charges on your personal mobile or landline phone bill are a genuine business claim. If they are, your company can claim phone expenses for such work-related calls. What’s more, it can reclaim the VAT on business phone charges. However, you can’t claim for any part of the line rental. Basically, 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, when you claim phone expenses, splitting out the cost of work-related calls can be difficult. This is due to the way that phone companies now package phone costs with free minutes, etc. Therefore, if you’re not able to separate work calls from personal phone bills, you’re unable to 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 already pay for your personal calls.

Business broadband expenses -can I claim internet as a business expense?

Home internet business expense and percentage of phone bill tax-deductible

When you work at home, what should we think about when we consider can I claim my home internet as a business expense and when are internet expenses tax-deductible? Basically, if your home office broadband is in your personal name, you may ask how much of my internet can I deduct for business? Basically, the general rule for business broadband for home workers is you can’t claim for your home broadband cost as a contractor expense unless you can split out the business broadband costs element or approximate business element.

It’d be fair to say, if you use your home office broadband significantly for work reasons, and you estimate your contractor broadband costs to be 50% of your overall usage, then you are ok claiming internet as business expense and can put through 50% of the overall broadband cost as your internet tax deduction. In turn, the broadband for home office will save company tax. On the other hand, if you’re self-employed, you could make the relevant claim for the cost of broadband charges as a home internet tax deduction via your personal tax return.

If you’ve no actual broadband contract at home and need internet access (e.g., on your phone) to carry out your trade, then you can claim any internet for business related costs for your company.

Claim for phone and broadband costs -other considerations 

When you look at small business broadband and phone deals, there’s more to consider as we show below. 

Full fibre broadband 

This type of broadband is fairly new on the scene and most of the top UK suppliers will have this available. It’s a type of high-speed broadband and uses fibre optic cables for transferring data. This is faster than a normal broadband connection which uses standard copper cables.

Static IP address 

An IP address is a unique digital reference for a specific point on the internet. Therefore, what’s the benefit if you get a static IP address as part of your phone line and broadband for business? Basically, this is a fixed Internet address rather than one that is dynamically assigned to you each time you connect. When it’s static, it always stays the same, making it possible for users and other businesses to find you on the internet. You’d need a static IP address if you were hosting your website or running an e-commerce business. Most UK companies charge a small extra fee for a static IP address.

Download/upload speed 

When you have broadband for your business at home, you may wish to check the download and upload speeds. You can do tests online. Generally, a good download speed is at least 100 Mbps, while a good upload speed is at least 10 Mbps. You may need further research in this area if you have customers connected to your services and are streaming data to them. Asa result, you can look into some high-speed internet for home office.
