Why is the "Age Amount" deduction different for myself ($5,293) and my wife ($6,332), who is two months younger?

[TonyC11 · Accepted solution]

Age amount is not a deduction. It is one of many Schedule 1 non-refundable credits.

Also, Age amount of Credit is dependant on your Net Income. As your Net rises above a base amount ( $34873.00) the credit is reduced at 15% of the difference).
