My computer has just **** itself...with my database of classes on it It's the only rference I have of the amount of classes i've taught this year agghhhh!

What i'm wondering is if the tax depart can tell me (by looking at my ABN) how much i've earned? Or if I make an estimated guess and it's wrong will they know and will I get into a lot of trouble?

Anyone know any other way I can find out? A few gyms have told me they can tell me but I worked for one gym that is now closed and I can't get hold of the owner...

Any ideas anyone??
