the process works like this.
1, Company earns $18,000 in share holder profits.
2, Company pays $5,200 in tax
3, Company pays $12,600 as dividend with $5,400 franking credit = $18,000
4, Investor declares $18,000 income on tax return.
5, tax office says no tax is payable on the $18,000
6, Tax office hands back the $5,200 franking credits
7, Investor now has $18,000 to spend, just as if they earned $18,000 in bank interest.
How about:
3, Company pays $18,000 as dividend with $0 franking credit = $18,000
