Unsure How to Declare My Income for Unmarried Partner Visa as It Has Just Changed

Hi everyone!

Apologies for making another post in such a short amount of time, but I'm really struggling to find a solid answer on this.

I am currently hoping to apply for an unmarried partner visa with my girlfriend who is from China, but is currently living with me in the UK on a student visa. My salary has just changed from £27,200 to £29,000. As I have not been earning £29,000 for the past 6 months, should I declare my annual income as still £27,200 even though my latest bank statement (and statement from my employer) will say that I am now earning £29,000? Or should I declare my annual income as £29,000, but also choose the option that states I have been earning "The same amount continuously, below the financial requirement amount"?

Thanks in advance!
