You are required to report your Plld information as benefits of employment on your self-assessment return, therefore there may be additional tax to pay.
If you believe that additional tax may be due relating to a particular expense, we suggest that you discuss with your accountant whether or not you still wish to claim the expense through the company.
By making sure that the expenses you put through your company are wholly, necessarily and exclusively for the purposes of your trade, these can be paid to you tax free.
