I know the minimal compulsory employer superannuation contribution is 9%. i wonder what's the maximal employer contribtion rate? I heard it could be as high as 45% but I couldn't find more info. Can my company (sole director) contribute (for example) 20%, which is $30,000 and I contribute $ 20,000. Are there any benefits If increasing employer contribution from 9% to 20%? I'm doing salary sacrifice as well. Thanks in advance for your input.
