CSS Profile - Tax included or not?

<p>Hi all,</p>

<p>I'm filling in the CSS profile atm and as I am an international, don't really have anyone to ask about these things. </p>

<ul>
<li><p>First just to confirm - every number I enter is gross (before tax) correct? Nothing on it asks for net income am I correct to say?</p></li>
<li><p>For things like Interest earned, can close approximates be given, or will I need to check exact amount. It can be extremelly difficult trawling through bank statements on all accounts to check the level of interest earned. </p></li>
<li><p>I personally don't have to file any tax returns do I? (I earned no income in our country's most recent tax year).</p></li>
</ul>

<p>Thanks greatly for your help.</p>

<p>I am an international student and I have the same problem:
PI-155I: "Enter the income parent 1 earned or expects to earn from work during his or her country's most recent tax year."
Is that the income before taxes?</p>
