## What this file is

**Obligation category:** Income tax
**Functional role:** Router and decision framework for everything that reduces Australian tax
**Status:** Source-cited draft, pending accountant review

Australia has no single "reliefs and allowances" concept. Four mechanisms sit behind that idea and
they behave differently, so getting the mechanism right matters more than finding the item.

## Section 1 - The vocabulary map

**The vocabulary map**

| Mechanism | What it reduces | Typical value of $1 | Australian examples |
| --- | --- | --- | --- |
| **Deduction** | Assessable income, producing taxable income | The taxpayer's marginal rate, so worth more to higher earners | Work-related expenses, rental expenses, business expenses, personal super contributions, donations to deductible gift recipients |
| **Capital allowance** | Assessable income, spread over time or immediately | Marginal rate, but timing changes the value | Decline in value under Division 40, capital works under Division 43, instant asset write-off |
| **Tax offset (also called a rebate)** | Tax payable, after tax is calculated | $1 of tax, regardless of marginal rate | Low income tax offset, seniors and pensioners tax offset, foreign income tax offset, private health insurance rebate |
| **Concession or exemption** | The base itself, or the rules that apply to it | Varies | Small business CGT concessions, the 50% CGT discount, main residence exemption, small business entity concessions |

**Why the distinction matters.** A deduction of $1,000 saves $320 for someone on a 30% marginal
rate plus the 2% Medicare levy, and $470 for someone on the top rate. An offset of $1,000 saves
$1,000 for both, but only if there is $1,000 of tax to reduce.

**Refundable and non-refundable offsets.** Most offsets are non-refundable: they can reduce tax
payable to zero but do not pay out an unused offset. The treatment of any unused amount depends
on the offset: some can transfer, carry forward or reduce other liabilities. Some offsets are
refundable, so the excess is paid out. Franking credits attached to franked dividends and the private health insurance
rebate are refundable. Check this before telling a taxpayer an offset is worth anything to them.

## Section 2 - Scope statement

This skill covers:

- The order in which deductions, offsets and concessions are applied.
- The general deduction test, apportionment, the capital and revenue boundary, and the specific
  denial provisions.
- The standard deduction for work-related expenses that applies from the 2026-27 income year.
- Substantiation requirements and record retention.
- The main tax offsets and how refundability changes their value.
- Where each specialist rule set lives.

This skill does NOT cover:

- The detailed computation of any single item. Each has its own guide.
- GST credits. Those are not income tax deductions. See `australia-gst.md`.
- Fringe benefits tax. See `au-fbt-year.md`.
- State and territory concessions, including duty concessions and land tax exemptions. See
  `au-stamp-duty.md` and `au-land-tax.md`.

## Section 3 - The order of operations

- **Order of operations** — Apply the statutory offset priorities, including the rules for any unused amount. 1. Work out assessable income, including net capital gains. 2. Subtract allowable deductions to get taxable income. 3. Apply the rates for the income year to taxable income, giving basic income tax liability. 4. Calculate the Medicare levy and any Medicare levy surcharge separately. 5. Apply offsets to basic income tax liability in the order in section 63-10. For each unused amount, follow its statutory treatment: application to another liability, transfer, carry-forward, refund or loss. See Section 8.2 for the Medicare levy exceptions. 6. Add the remaining income tax and levy liabilities, then subtract any refundable excess offsets. 7. Subtract amounts already paid: PAYG withholding and PAYG instalments.  _([ITAA 1997 (Cth) s 63-10](https://www.ato.gov.au/law/view/document?docid=PAC/19970038/63-10))_
- **Tax losses** — A tax loss arises where deductions exceed assessable income. A loss is carried forward, not converted to a refund, and its use is restricted for individuals by the non-commercial loss rules and for companies by the continuity of ownership and business continuity tests.

## Section 4 - Deductions: the decision steps

- **Deductions decision steps overview** — Identify the provision that allows the deduction before applying these steps. Steps 1 and 2 test general deductions under section 8-1. A specific deduction, such as a qualifying gift under Division 30, follows its own eligibility rules; failure of the section 8-1 test does not decide that claim. For specific deductions, apply steps 3 to 6 using the relevant provision's limits, apportionment, timing and evidence requirements.  _([ITAA 1997 (Cth) s 8-5](https://www.ato.gov.au/law/view/document?docid=PAC/19970038/8-5))_

### Step 1 - Is there a nexus with assessable income?

- **Nexus test** — A loss or outgoing is deductible to the extent it is incurred in gaining or producing assessable income, or necessarily incurred in carrying on a business for that purpose.  _([ITAA 1997 s 8-1](https://www.ato.gov.au/law/view/document?docid=PAC/19970038/8-1))_
- **ATO three conditions for employees** — The ATO states the test for an employee as three conditions: the taxpayer spent the money and was not reimbursed, the expense directly relates to earning income, and there is a record to prove it. An employer instruction to buy something does not by itself make it deductible.  _([ATO, Claiming deductions](https://www.ato.gov.au/individuals-and-families/income-deductions-offsets-and-records/deductions-you-can-claim/how-to-claim-deductions))_

### Step 2 - Is it private, domestic or capital in nature?

- **Private, domestic or capital exclusion** — Section 8-1 denies a deduction to the extent the outgoing is private or domestic, or capital or of a capital nature. Ordinary travel between home and work and daily lunches are private. If section 8-1 excludes capital expenditure, check whether it qualifies under another regime: Division 40 decline in value, Division 43 capital works, the CGT cost base, or a specific write-off provision such as section 40-880 for certain business-related capital expenditure.

### Step 3 - Does a specific provision deny or limit it?

- **Specific denial or limit provisions** — Deductibility can be denied even where the nexus exists. Examples include entertainment expenses, penalties and fines, holding costs for vacant land held by most non-business taxpayers, and general interest charge and shortfall interest charge incurred on or after 1 July 2025. Check the specific provision before allowing an unusual item.

### Step 4 - Apportion

- **Apportionment** — Where an expense serves both an income-producing and a private purpose, only the income-producing share is deductible. The apportionment method must be reasonable and documented. A percentage guessed at year end is not a method.

### Step 5 - Is it incurred in this income year?

- **Timing / incurred** — "Incurred" is not the same as "paid". Prepayment rules can spread a deduction over the period the benefit covers, with a 12 month exception available to individuals for non-business expenditure and to small business entities. For a specific deduction, use its own timing rule. For example, a qualifying gift of money under Division 30 is generally deducted in the income year the gift is made.

### Step 6 - Is there evidence?

- **Evidence** — See Section 6. Substantiation is a condition of the deduction, not an audit formality.

## Section 5 - The standard deduction for work-related expenses, from 2026-27

- **Standard deduction for work-related expenses** — A standard deduction of up to $1,000 for work-related expenses applies to Australian tax residents who earn income from work. It commences on 1 July 2026 and first applies to the 2026-27 individual tax return. It does not apply to the 2025-26 return. AUD
