How is income tax calculated and what is the rate of income tax?

We love to grumble about them, but taxes keep our public services alive. The government hopes to collect tens of billions in taxation revenue each year  – even though this year has seen the announcement of tax cuts across all brackets.

How much tax will you be contributing?  For individual taxpayers who are Australian residents for tax purposes, the following rates apply for the 2018/19 financial year.

Taxable income Tax on this income
0 – $18,200 Nil
$18,201 – $37,000 19c for each $1 over $18,200
$37,001 – $90,000 $3,572 plus 32.5c for each $1 over $37,000
$90,001 – $180,000 $20,797 plus 37c for each $1 over $90,000
$180,001 and over $54,097 plus 45c for each $1 over $180,000

How much do you have to earn to pay tax?

The ATO advises you will have to pay income tax on every dollar over $18,200 that you earn; earnings below that are tax-free. In addition to the rates in the table above, most taxpayers are also charged a Medicare levy of 2%. 

The ATO also notes children under 18 who earn “unearned income” (that is, income that does not relate to employment, compensation or the proceeds of an estate) are subject to a higher tax rate of up to 66%. If you have a child who may be in this situation, it could be a good idea to discuss this with your registered tax adviser.

What is taxable income?

Income tax is applied to “taxable income”. So: what is your taxable income?  The ATO defines taxable income as follows:

Your taxable income is the income you have to pay tax on. It is the term used for the amount left after you have deducted all the expenses you are allowed to claim from your assessable income. Assessable income – allowable deductions = taxable income.

Following on from that, the ATO offers the following examples of assessable income:

  • salary and wages
  • interest from bank accounts
  • dividends and other income from investments
  • bonuses and overtime an employee receives
  • commission a salesperson receives
  • government payments such as the age pension, newstart allowance and youth allowance
  • rent

Some income streams, such as some allocated pensions, some government pensions and some education payments are not assessable income.
