The wordings of: “The dividends received from Flame are eligible for the 80% dividends received deduction.” are bonus to the examinees.
Becker's F6-49 about Investee's Undistributed Earnings lays this out:
ALL PERMANENT DIFFERENCES
Ownership 0-19%…………. 70% Exclusion
Ownership 20-80%……….. 80% Exclusion
Ownership over 80%……..100% Exclusion
I found the above lay-out as ridiculously complicated.
It could have been stated is a simpler note such as:
0-19% share => 30% Taxable
20-80% share => 20% Taxable
The rest is not taxable!
