earnings for Tier 1 extension

[Giri]

Hi,

I extended my tier 1 in 2010 for 3 years. That time I showed my net profit as my savings and claimed points for that. Now my 2nd extension is due. To get the points for the earning do I have to show the net profit or gross earnings to claim points? I went through home office guidance but it confuses me.
Can anyone advise me?

Gross earnings = Actual earnings (including taxes) + Operational expenses

Actual earnings (including taxes) = Total amount invoiced - Operational expenses

Net profits = Actual earnings - Taxes

you can show Actual earnings including taxes, not Net profit, as your income to claim points
