Legally , can you Salary Sacrifice (Employee Wage) into a "Line of Credit" Mortgage.?

Question

with the Governments Approval?

Answer 1

As long as the appropriate amount of tax is withheld by the employer, than the employee can have their wage paid into any bank account that they want. When you say salary sacrifice, it implies that you are hoping to get some sort of tax benefit from contributing to your mortgage. You won't.
