My parents have rented out a commercial property for 30 plus years. They had a business account at their bank in joint names and each declared 50% of the rent on their tax returns but were not a limited partnership for tax purposes.
In the last tax year they sold the property. It transpired that the property was in my mum's name only.
We need to make a capital gains submission. Given that the rent and the sale proceeds went into their joint account and any expenses over the year were paid for out of this joint account can they each report 50% of the gain on their tax returns and deduct the £12k to get the taxable gain? Or is the gain deemed to be solely my mum's as she was the legal owner of the property?
