I run a sole proprietorship and pay both business expenses and personal expenses with one credit card. Each year the relative proportions change.
In the past income year I received a credit card repayment protection insurance payout for this credit card that is quite substantial. I understand this is reportable income.
What is the appropriate way to allocate this income between what is personal or business e.g Should it be 50/50 as you might do when you split interest income for a joint bank account, or should I estimate how much of the credit card expenditure belongs to the the business (the debt which the insurance is repaying/covering goes back many years)?
Thank you
