Director working from home - claim proportion of mortgage interest?

Hi After reading this article: https://www.taxinsider.co.uk/use-of-home-as-office-is-hmrc-short-changing-taxpayers-ta It sounds like if you work from home and use one room as a dedicated office, you can claim costs such as mortgage interest on that proportion, is that correct? Scenario i'm thinking is a Ltd company which is run from home and theres a dedicated home office, can you claim mortgage interest back on company accounts for that 1 room?

Hi ,
 

Thank you for your query. Mortgage interest is a cost of borrowing money and not a cost of providing business accommodation. The case of Baird v Williams (71TC390) confirms that it is not a deductible expense. Further information can be found in EIM32820 - Other expenses: home: household expenses: expenses that are not deductible and BIM47820 - Specific deductions: use of home: specific expenses       , the guidance applies only to income tax and therefore personal tax expenses. If you require further advice on this matter, please seek professional help through a financial advisor or accountant . Thank you .

Not HMRC...even if Baird v Williams didnt apply (havent checked) this would make a proportion of your home non residential as in claiming you would be saying it is a business premises (business rates implications?) and also therefore liable to capital gains tax on sale.
