If you have not provided us with your TFN then concessional contributions will be taxed at a much higher rate than they need to be and you will miss out on other benefits.
All employer contributions will be taxed at 47% instead of 15%
Before tax (salary sacrifice) contributions will be taxed at 47% instead of 15%
We can’t accept any personal after-tax contributions
If you’re eligible for the government co-contribution you won’t get it
Any benefit payments made may be taxed at a higher rate
