I know that claiming two tax free thresholds from two different employers will create a tax debt at the end of the financial year (both incomes should total between $65,000 to $75,000). However, if this tax liability is set aside and is earning interest in a savings account throughout the year, wouldn't this be better than paying tax as you go? I also know that I would have to pay tax on the interest that is gained on this tax liability, but this is only a fraction of the interest gained, not all the interest.
However, I am wondering about the legal ramifications of this? Does anyone else do this in purpose? If not, why not? It does seem like an easy way to make extra dollars if you you are disciplined enough to set aside your tax liability.
Probably. If you can't pay that tax debt when it's due and they find out you claimed the tft twice, you'd likely get penalised of something. Just a guess.
