When last did you look at how much you're contributing to your superannuation fund? If it's not top of mind, it will become just that when you get a fine from the Australian Tax Office for putting in too much.

Remember, the super contribution rules changed last year. As of July 1 the concessional, or pre-tax, contribution cap was lowered to $25,000 a year for everyone. Before that it was $30,000 a year for those under 50 and $35,000 for those above.
