As mentioned in the previous article once certain conditions are satisfied host family has to register with HRMC as an employer.
As an employer you have a legal obligation to operate PAYE on the payments you make to your employees if their earnings reach the National Insurance Lower Earnings Limit (LEL). For the tax year 2012-13 this is £107 a week, £464 a month or £5,564 a year
How much National Insurance you have to pay for your employee??
Employee can earn up to £146 a week (2012-13) before the employer pay any National Insurance contributions. This is known as the 'primary threshold'.
However, as long as the employee earns more than £107 a week (2012-13) they can still build up their entitlement to a State Pension and certain other benefits. This is known as the 'lower earnings limit'
a) if you pay your employee more than £146 a week and up to £817 a week, you pay 12 per cent of the amount earned between £146 and £817
b) if the employee earns more than £817 a week, you also pay 2 per cent of all your earnings over £817
