VAT
To reclaim VAT on mobile phone costs via your limited company the contract for the phone as well as the associated invoices need to be in the name of the business.
If this is the case, then you can reclaim VAT on the full cost of the invoice, including any associated line rental.
However, this assumes that your business has a policy that employees cannot use the phone for private calls, and any private calls that breach this policy are genuinely minimal. If you are a director of a limited company, it may be hard to argue that you personally breached the rules of your own business.
If you have substantial private calls on this contract, you will need to apportion your input VAT claim to reflect line rental plus business use only.
Corporation Tax
Like VAT the contract should ideally be in the name of the company to claim the full cost against your profits for Corporation Tax.
Unlike VAT where the contract is not in the name of the business, you can still claim a portion of the costs against Corporation Tax, but the claim needs to be apportioned to represent only the business portion of the call charges, excluding any line rental.
