Exactly what surprised said.

We are a company but didn't branch off like yours does. Centrelink will want to know the profit/loss for the parent company since you're considered a director AND they're going to be interested in the trading company as a whole since you own it on paper.

We had to provide tax returns, p&l statements, accountants letters etc and after all of that we weren't entitled to anything! (The joy of business ownership and centrelink)

If it's a new company you give an estimate for FTB purposes, they may go off your last years figures for parenting payment with a revision at tax time once returns are lodged.
