I have two part time nanny jobs, one uses Nannytax to operate PAYe for them, the other does it all herself. She doesn't pay my NI as it's under the threshold (though it may go above soon, boss is willing to pay it from my gross wage if it does obviously!) But she received a letter mentioning student loans repayments. This was a few weeks back and I've completely forgotten what it said so will have to double check, but I want to know if I'm supposed to pay repayments on that job's wage? I'm sure I'm not paying it on my other job either, my earnings are only around £14,200 gross a year with both incomes combined so I thought I didn't have too?! I did earn more in the last tax year though.
