Help in filling the Financial requirement in FLR(m)

[moumita10]

I came in UK in Dec, 2015 on spouse visa. Now I have to renew my spouse visa and I want to use my financial statement to meet 18600 pound as we have no children. I am bit confused about the financial part of the form.
In the last financial year 2017-2018, I was employed as well self employed earning around 20000 pound. 16000 (FROM EMPLOYMENT)+4000 (self employment). Basically I was working in a college full time till feb and from march 2018 I started working in an induatry as a research consultant earning around 30000 but I have to pay my own tax(self employed). I already filed the self assessment form and already paid that tax in that last financial year 2017-18. I work as a part time in that college and full time research consultant from march 2018. For meeting the fimamcial requirement in FLR(M) I will use 2018-19 or 2017-18. Please help me in this regard. The whole thing is very confusing for me.....Need help urgently
