Australians can boost their superannuation and halve the amount of tax they pay. From July 1, 2021, workers will be able to put up to $27,500 a year into their retirement savings, up from $25,000, and only pay 15 per cent tax. That is half the usual marginal tax rate of 32.5 per cent for most workers earning between $45,001 and $120,000 a year. The 15 per cent concessional rate is a third of the 45 per cent rate for those earning more than $180,000. Accountant Ben Johnston, the director of Johnston Advisory, said workers could ask their employer to top up their superannuation through salary sacrificing.
