uk citizen with australian wife... self employed please help

Hi, I am a UK national living in the UK with my wife who is from Australia on a t5 visa.
We have recently been filing in the FLRM form and appear to have hit a speed bump.

I am recently self employed (starting in November 2013) physiotherapist with adequate finances to support the both of us. However the form asks to provide information from either the last financial year or last two financial years. This is where the problem is. I have invoices and bank statement to provide information regarding the last 3 months and a letter from a company which source my work stating my hourly rate and my expected hours per week for the forseable year which would see me well above the threshold. I am fully registered with HMRC although no information has been sent out to me.

If I would to state my income from self employment in the last financial year as 0 would this see our application refused dispute evidence of the last 3 months and the accompanied letter from the company I work with.

If anyone can shed some light I would be extremely greatful, her expiration on the current visa ends on the 6th or march and so swiftness is key.

Thank you in advance.
