I was just about to sign the contract when the family dropped a bombshell ... they use nanny tax company to sort out payslips etc but they said they only declare part of the income (up to the tax free allowance which is now 10k per annum I believe) and the rest is given as cash in hand not to be declared. I really like this family but this seems really dodgy and a deal breaker. That means that more than a third of my income would be undeclared. Are there really no severe enough legal implications to stop people doing this?
