nomind - you are 100% correct.
Geo123 - just did mine, initially let MaxBack Calculate the split, it gave all our donations to me.
Manually went into split $200 to spouse, balance to me, missed turning MaxBack off the first time.
After both splitting and turning MaxBack off - I picked up an extra $50 back on our refund. Tax Credit Calculation is correct (or looks like it), UFile for Windows is not adjusting for the $150 back on the first $200 when making the decision on how to split family donations.
If you have over $200 in donations and live in Alberta, I'd recommend manually splitting and turning MaxBack off (or at least until UFile corrects the situation).
