Common questions

Who is a resident for Australian tax purposes?

Residency for tax is tested under the ordinary concepts test, the domicile test, the 183-day test, and the Commonwealth superannuation test. Residents are taxed on worldwide income, non-residents on Australian-sourced income only. The tests are fact-sensitive and often litigated.

What is assessable income?

Assessable income is the sum of ordinary income and statutory income. Ordinary income is receipts according to ordinary concepts (salary, business income, rent, interest). Statutory income is anything made assessable by a specific provision of the tax legislation.

Income Tax Assessment Act 1997 (Cth) ss 6-1, 6-5, 6-10
What is capital gains tax?

Capital gains tax is not a separate tax but is income tax on capital gains made on CGT events — usually the disposal of CGT assets. Individuals and trusts may be eligible for a 50% discount after holding an asset for 12 months or more.

Income Tax Assessment Act 1997 (Cth) Part 3-1
What is the main residence exemption?

A gain on the sale of a taxpayer's main residence is usually exempt from CGT. Special rules apply to properties used to produce income, absences, dwellings on land exceeding 2 hectares, and deceased estates. Foreign residents lost access to the exemption from 1 July 2020.

Income Tax Assessment Act 1997 (Cth) Div 152
What is Division 7A?

Division 7A treats certain payments, loans, and forgiven debts from a private company to a shareholder or associate as unfranked dividends unless they are formally documented as Division 7A compliant loans with set interest rates and minimum repayments.

Income Tax Assessment Act 1936 (Cth) Division 7A
What is GST and who must register?

GST is a 10% broad-based consumption tax administered by the ATO. Entities carrying on an enterprise with GST turnover of $75,000 or more ($150,000 for non-profit bodies) must register. Taxi and ride-sourcing drivers must register regardless of turnover.

What is the Part IVA anti-avoidance rule?

Part IVA is the general anti-avoidance rule. It allows the Commissioner to cancel a tax benefit obtained under a scheme where, having regard to specific factors, it would be concluded the dominant purpose of a person entering the scheme was to obtain the tax benefit.

How are discretionary trusts taxed?

A discretionary (family) trust does not pay tax itself — its net income is assessed in the hands of beneficiaries to whom it is distributed, or taxed at the top rate in the trustee's hands if not distributed. Distribution patterns can attract Part IVA and section 100A scrutiny.

Income Tax Assessment Act 1936 (Cth) ss 97, 99A, 100A
What is section 100A of the ITAA 1936?

Section 100A is a long-standing anti-avoidance rule targeting reimbursement agreements where a trust beneficiary is presently entitled to income that is effectively enjoyed by another person. The ATO issued new guidance in TR 2022/4 / PCG 2022/2 flagging increased compliance focus.

Income Tax Assessment Act 1936 (Cth) s 100A
How do I object to an ATO assessment?

A taxpayer dissatisfied with an assessment can lodge an objection with the Commissioner within the prescribed period (generally 4 years for most taxpayers, 2 years for small business and individuals). The objection must be in writing and state fully and in detail the grounds.

Taxation Administration Act 1953 (Cth) Sch 1 Part IVC
Can I appeal an ATO decision?

Yes. If an objection is refused, the taxpayer can either apply to the Administrative Review Tribunal for merits review or appeal to the Federal Court on a question of law. Different cost and evidence rules apply in each forum.

What are the general interest charge and shortfall penalties?

GIC accrues on unpaid tax liabilities at a rate set quarterly. Shortfall penalties under s 284-75 apply to inaccurate statements at 25% (lack of reasonable care), 50% (recklessness), or 75% (intentional disregard), with remissions possible for voluntary disclosure.

Taxation Administration Act 1953 (Cth) Sch 1 Div 284
What is transfer pricing?

Transfer pricing rules require international related-party dealings to be on arm's length terms. The ATO can reconstruct dealings and impose adjustments where terms differ from those that independent parties would have agreed, with significant penalties and documentation obligations.

Income Tax Assessment Act 1997 (Cth) Subdiv 815-B
How are cryptocurrency transactions taxed?

The ATO generally treats cryptocurrency as a CGT asset, so gains and losses on disposal are capital in nature unless the taxpayer is carrying on a business of trading crypto. Personal use asset exemptions are narrowly limited.

TD 2014/26; ATO guidance on crypto
What is fringe benefits tax?

FBT is a tax paid by employers on the value of non-cash benefits (cars, loans, entertainment, housing) provided to employees or their associates. The FBT year runs from 1 April to 31 March, and the FBT rate is the top marginal income tax rate plus Medicare levy.

Fringe Benefits Tax Assessment Act 1986 (Cth)
What is the CGT discount?

The CGT discount reduces capital gains by 50% for individuals and trusts, or 33.33% for complying superannuation funds, where the asset was held for at least 12 months. Companies are not eligible for the CGT discount. Foreign resident individuals lost access to the discount from 8 May 2012 on a prospective basis.

Income Tax Assessment Act 1997 (Cth) Div 115
What is the difference between tax evasion and tax avoidance?

Tax avoidance is arranging affairs within the law to reduce tax (subject to anti-avoidance rules). Tax evasion is deliberately concealing income, fabricating deductions, or using false documents — it is a criminal offence that can attract imprisonment and penalties.

Criminal Code Act 1995 (Cth) Division 135
How much does tax advice cost in Australia?

Tax advice fees vary widely. A private binding ruling application may cost $5,000-$20,000 in legal fees. Complex restructuring, disputes, or transfer pricing matters can run into hundreds of thousands. Most tax lawyers charge on time-cost basis with regular estimates.
