I recently bought a garage for tools, furniture and white goods. Is it tax deductible? 

Arthur Weller replies:  

It seems to me from your question that you are a self-employed trader. If so, expenditure to purchase a garage to store tools is capital expenditure, and not tax deductible from your annual profits (i.e. not a revenue expense). Even though certain items of capital expenditure are now tax deductible for those who use the cash basis, the purchase of a garage is an excluded item. Possibly you could claim the 2% structures and buildings allowance (SBA). See HMRC’s Capital Allowances manual. However, you mention that you are also using the garage for furniture and white goods, which makes me think that maybe it also has a non-trade (residential) use, which would prejudice your claim for SBA.
