I underestimated both of them, and e-tax said I had no tax owing, just various credits. The A and B I got back were both slightly over the minimum supplement - for *one* child.

Last year we did our tax early and had to wait months for the FTA/FTB stuff to come through (I got my normal return within 2 weeks) because my ex hadn't done his tax. He's actually never been my partner for tax reasons, I wasn't with him long enough ... yet my tax and a fair slab of my income each year is 100% reliant on him. Lovely the way someone you shagged a few times in 2000 is financially attached for the next 18 years, eh?
