Adjusted taxable income for you and your dependants 2023

What is adjusted taxable income

Your ATI is the sum of the following amounts:

• taxable income (excluding any assessable First home super saver released amount)
• adjusted fringe benefits total, which is the sum of
  • reportable fringe benefits amounts received from employers exempt from fringe benefits tax under section 57A of the Fringe Benefits Tax Assessment Act 1986 multiplied by 0.53, and
  • reportable fringe benefits amounts from employers not exempt from fringe benefits tax under section 57A of the Fringe Benefits Tax Assessment Act 1986
• reportable employer superannuation contributions
• deductible personal superannuation contributions
• certain tax-free government pensions or benefits received by the person
• target foreign income (income and certain other amounts from sources outside Australia not included in your taxable income or received as a fringe benefit)
• net financial investment loss (the amount by which the person's deductions attributable to financial investments exceeded their total financial investment income)
• net rental property loss (the amount by which the person's deductions attributable to rental property exceeded their rental property income)

less

any child support payments the person provided to another person.

We use ATI to work out if:

• you can include a base amount in the zone or overseas forces tax offset (question T4)
• you can claim the invalid and invalid carer tax offset (question T5)
• your child is considered a dependant for Medicare levy purposes (question M1)
• you are entitled to government super contributions (question A3).

If you want to claim a tax offset at questions T4 or T5 and you have dependants, you will need your and your dependant’s ATI for the relevant period to work out:

• whether you are eligible for a tax offset
• the amount of any tax offset you are entitled to.

For the meaning of dependant and maintaining a dependant, see Special circumstances and glossary 2023.

Calculate your ATI

You can use either our Income tests calculator or worksheets 1a and 1b. If you use the calculator and have to either work out a dependant's ATI for part of the year or a deceased's ATI, you need to read the instructions below.

Working out the ATI of a person for the whole year

If you are working out the ATI of a person for the whole year, you can get the amounts for worksheet 1b from the person's tax return. Table 1 shows you where the relevant amounts are on the tax return.

Table 1 – Working out ATI

For Worksheet 1b	The amount comes from
a	Taxable income or loss on page 4 of the tax return (excluding any assessable First home super saver released amount)
b	The sum of: question IT1 – label N on page 8 in the tax return, multiplied by 0.53 and rounded down to the nearest dollar, and question IT1 –label W on page 8 in the tax return
c	question IT2 – label T on page 8 of the tax return
d	question D12 – label H on page 15 in the supplementary tax return
e	question IT3 – label U on page 8 in the tax return
f	question IT4 – label V on page 8 in the tax return
g	question IT5 – label X on page 8 in the tax return
h	question IT6 – label Y on page 8 in the tax return
j	question IT7 – label Z on page 8 in the tax return

Working out a dependant's ATI for part of the year

If you are working out a dependant's ATI for part of the year, you cannot use the figures from their tax return. Instead, you must work out the amounts for the relevant period and complete the calculator or worksheet using these figures. The instructions at each offset question will tell you what to do.

Completing a tax return for a deceased person

If you are completing a tax return for a deceased person, or your spouse died during the year and you need to know their ATI for the whole of 2022–23, their ATI is the amount in the calculator or at row k below:

• divided by the number of days the person was alive in 2022–23, and
• multiplied by 365.

This is the deceased person's ATI for the whole of 2022–23.

Working out a person's ATI for the relevant period

Determine the period for which you need to work out the person's ATI (start date and end date).
