Can my company claim my mobile phone and broadband?

Updated 27 June 2026
The short answer

Yes, if you do it the safe way. Put one mobile phone in the company's name and the company can pay the whole bill tax-free, even if you make personal calls on it too. The trap: if the phone is on your own contract and the company pays you back, that lands you with a tax bill, and only your business calls count. Broadband: if your home already has it, there's nothing extra to claim. A brand new line, in the company's name, that you only got for work, can be claimed. We add the right figure in for you.

Can my company pay for my mobile phone?

Yes, and it's one of the better perks of running your own company, as long as you set it up the right way.

The rule is simple: the company can give you one mobile phone, and the whole cost is tax-free, the handset, the monthly line rental, and your calls. The clever bit is that it stays tax-free even if you also use the phone for personal calls and texts. You don't have to split out work from personal.

There's one condition, and it's the thing everyone gets wrong, so read the next part carefully.

The safe way vs the trap: whose name is the contract in?

This single choice decides whether the phone is tax-free or whether it hands you a tax bill.

The safe way, a company contract. The phone contract is in the company's name, the company pays the provider directly, and the company gives you the phone to use. Done this way, one phone is tax-free even with personal use. This is the route to take.

The trap, your own contract. The phone is on your personal contract, in your own name, and the company pays you back for the bill. This is not tax-free. HMRC treats that money as a payment to you, so it can land on your tax bill. On a personal contract, the only part the company can claim is the cost of your actual business calls, and you'd have to pick those out of your itemised bill, line by line. The monthly rental and your personal calls don't count.

So the difference between the two is huge. Same phone, same usage, but a company contract is clean and tax-free, while paying back a personal contract is fiddly and can cost you. If you're going to claim a phone, put the contract in the company's name.

Can my company pay for my home broadband?

This one surprises people, so here's the honest answer.

If your home already has broadband, there's usually nothing to claim. You were already paying for that line before you started working from home, so working from home doesn't add any extra cost, and the company can't claim a cost that isn't really there.

If you didn't have broadband before and you got a connection only because you need it to work from home, that's different. That new line is a genuine extra cost of working, and the company can cover it. The clean way is to put the new connection in the company's name so it's plainly a business cost from the start.

The simple test is the same one behind all of this: the company can cover the extra cost that working from home creates, but not a cost you'd be paying anyway. An existing broadband bill is a cost you'd have regardless, so it stays personal.

A quick example

Say you run a small company from home and you want to put your phone and internet through it.

  • You take out a new mobile contract in the company's name at £20 a month. The company pays the provider directly. The full £20 a month is tax-free, even though you also use the phone for personal texts. That's the safe route.
  • You already had home broadband at £30 a month before you started working from home. There's no extra cost here, so there's nothing for the company to claim. The broadband stays your personal bill.

If instead you'd had no broadband and put in a new £30-a-month line in the company's name purely to work, the company could cover that £30, because it's a real extra cost of working.

How SimpleReturns handles it

Tell us about your phone and broadband and we add the right amount into your costs, the full bill for a phone in the company's name, the business-call share if it's on your own contract, and a new work-only broadband line where it qualifies. We keep an existing personal broadband bill out of the company, so you don't accidentally hand yourself a tax bill. You see every figure before anything is sent.


Common questions

Can my company pay my whole mobile phone bill?

Yes, if the contract is in the company's name and it's your one company phone. Then the handset, line rental and all your calls are tax-free, even your personal ones.

The phone is in my own name and the company pays me back, is that okay?

That's the trap. Paying back a personal contract isn't tax-free, it can land on your own tax bill, and only your actual business calls can be claimed (not the rental or personal calls). The safe fix is to move the contract into the company's name.

Can my company claim my home broadband?

Only if it's a genuine extra cost. If your home already had broadband, there's nothing extra to claim. If you got a new line only because you need it to work from home, the company can cover that, best put in the company's name.

What if I use one phone for both work and personal calls?

That's fine on a company contract, one phone stays tax-free even with personal use, so you don't need to split anything. On a personal contract, only the business calls count, which is why a company contract is the easier route.

Can the company give me two phones?

The tax-free rule covers one phone per person. A second phone for the same person isn't covered the same way, so keep it to one if you want the simple, tax-free treatment.

Or, if your setup is unusual, like several phones across a team or a mixed-use broadband line, an accountant may be the better fit, and that's an honest call to make.
