repayment plan 2 fluctuating Salary

jimnew

I am paid a basic salary that is under the repayment threshold(plan 2  student loan years 2016-19) . I receive extra salary in bonuses some months 
Is the repayment worked out on your yearly salary or can earning   (£3000) trigger repayments even if your yearly salary is still under the threshold?

My understanding is that any bonus payments will trigger a student loan repayment based on the income for that month against the threshold.
 If at the end of the financial year eg 6 April 2020 to 5 April 2021, you earn less than the threshold you can apply for a refund. If you earn over the threshold then no refund is due, even if the amount you have paid is more than you would have done, had your monthly income been equal throughout the year.
