"That's wrong, I said — I'm wealthy. My accountant said 'that's how it works, that's what you have to do'. I can't stop it. I think it's outrageous for wealthy people to be getting money from the government."
He suggested a means test should be applied to the scheme to allow more wealthy Australians to be denied franking credits.
"Labor sold the whole thing incompetently," Smith told the SMH on Tuesday. "They should have put a threshold on it, so wealthy people like me would pay the tax, but pensioners and less well-off people would not meet that threshold."
The controversial tax system went from relative obscurity to a heated point of discussion after the Scott Morrison led Coalition labelled the Opposition's plan on the policy a "retiree tax".
Google searches for the term "franking credits" in Australia were flat in January this year — only to spike dramatically in May when it suddenly became a hot topic.
If you're an Australian shareholder, you get paid a dividend when the company makes a profit — and normally you would have to pay tax on that, just like you would with your regular wages.
But in 1987, then-treasurer Paul Keating introduced "dividend imputation credits" — also known as "franking credits" — which was designed to prevent double taxation.
Basically, it recognised the government already taxed companies' profits, so it wasn't fair to then tax an individual a second time.
So shareholders were given a sort of "I owe you" — they were able to deduct the amount the company had already paid in tax off their own taxable income.
But then in 2001, Peter Costello took it one step further and changed the rules to allow that tax deduction to be swapped for a cash refund.
It meant that even shareholders who didn't pay tax — like retirees — could still be given a cash refund from the ATO.
Smith's comments caused a stir online with many questioning why the outspoken millionaire didn't voice his position on the scheme during the election campaign.
"Dick Smith thinks Labor failed to sell franking credits policy. Perhaps he could have spoken up in support of it during the election," said Twitter user.
"Where was Dick three months ago when this debate about franking credits was raging," said another.
"So, the 'quiet Australians' are slowly getting loud," tweeted another. "A bit late Dick Smith, A bit late."
