Mobile phone and landline internet allowances/ claiming these business expenses

I understand I can claim as an expense the use of my mobile phone and my broadband data working from home for my free-lance teaching business. However, as I understand, I have to work out the business use from the personal use. How can I best do this? How do I record it? Any advice is much appreciated as I have not been claiming any of these expenses up to now.

Hi

You should review your usage of the mobile phone/landline to determine how much of it is used for private and business to then take the applicable percentage. This should be recorded as part of your record keeping.

Please see Expenses if you're self-employed: Overview

Thank you

Thanks very much for this information. I thought this would be the answer. I appreciate the response. Sincerely, Helen.
