for ftb, it's the current fin year. if you would receive all of your ppl in this fin year then you coult all of it in your estimate. if your ppl will roll past june 30, then you only count that which you will receive in this fin year. for the six month estimate of income for eligibility (under 75k combined for six months after birth) it is from baby dob to exactly six months later. fin yrs dont enter into it

on acombined annual income of 70-80k you will qualify fir ftba for 10/11 - if you are worried about OT impacting it you can wait until tax time to claim. depending on when you plan to return to work you may quilify for bot ftba and ftbb in the 11/12 fin yr
