Tier 2 extension for the 6th year

[benzujk]

Hello friends!

I have got my 5 year extension. My fifth year ends in January 2020. However, the salary scales for the indefinite leave is too high - £36000 for permanent residency. Therefore, I wondered whether I can apply for another year (6th year). I am not sure whether this could be possible. And if it is possible to apply for the 6th year after my 5 years, how much do i have to make annually to pass the threshhold?

I would be very grateful for your responses.

Kind regards,
Benzu
