Family loan - interest

My brother is loaning me money to cover a shortfall on a mortgage redemption. Since I don’t want him to lose out I want to pay him the same interest he was receiving from his savings account while I have the loan. Can the interest I pay still be part of his tax-free savings allowance as before, or will it become part of his taxable income.

Hi,

This will be treated as peer to peer lending. You can see guidance here:

Thank you.
