Australia Tax Guide 2026-27: Income Tax, CGT, Deductions & More

Tax time in Australia does not have to be stressful. Whether you are a salaried employee, a freelancer, an investor with shares, or a property owner, this guide walks you through everything you need to know about the Australian tax system for FY 2026-27 — from income tax brackets and the Medicare levy to capital gains tax, work-related deductions, and HECS-HELP repayments.

How Australian Income Tax Works

Australia uses a progressive tax system. Higher tax rates apply only to the portion of your income that falls within each bracket — not to your entire income. The more you earn, the more tax you pay on the additional dollars, but your lower earnings are still taxed at the lower rates.

Australian resident income tax brackets — FY 2026-27

Taxable Income	Marginal Tax Rate
$0 – $18,200	0%
$18,201 – $45,000	19%
$45,001 – $135,000	32.5%
$135,001 – $190,000	37%
$190,001 and above	45%

These rates apply to your taxable income — your total income minus allowable deductions. The Medicare levy of 2% is added on top, making the true effective marginal rates 21%, 34.5%, 39%, and 47% at each respective bracket.

Marginal Rate vs Effective Rate

Your marginal rate is the rate on the next dollar you earn. Your effective rate is the total tax you pay divided by your total income. On a $120,000 salary:

• Tax on the first $18,200: $0
• Tax from $18,201 to $45,000 (at 19%): $5,092
• Tax from $45,001 to $120,000 (at 32.5%): $24,375
• Total income tax: $29,467
• Medicare levy (2%): $2,400
• Total tax: $31,867 — effective rate 26.6%, marginal rate 34.5%

Every dollar saved through a legitimate deduction saves you tax at your marginal rate. That $1,000 work laptop deduction is worth $345 in tax savings at this income level.

The Low Income Tax Offset (LITO)

Tax offsets directly reduce your tax bill after it has been calculated — a dollar-for-dollar reduction, worth more than a deduction. The Low Income Tax Offset (LITO) for 2026-27 provides:

• $700 maximum offset for incomes up to $37,500
• Phases out between $37,501 and $66,667 at 1.5 cents per dollar

At an income of $37,500, the full $700 LITO effectively raises the tax-free threshold to approximately $22,575. The Low and Middle Income Tax Offset (LMITO) was a temporary measure that has now ended — do not factor it into FY 2026-27 planning.

Medicare Levy: Who Pays and Who Gets a Reduction

The Medicare levy is a 2% charge on your taxable income that funds Australia's public healthcare system. For FY 2026-27:

• Singles with taxable income below $26,000 are fully exempt
• Singles with incomes between $26,001 and $32,500 pay a reduced levy
• Above $32,500, the full 2% applies

The Medicare Levy Surcharge (MLS) is a separate charge of 1% to 1.5% for higher earners without private hospital insurance. It applies once income exceeds $93,000 for singles (or $186,000 for families) in FY 2026-27. Holding an appropriate private hospital cover policy can save money if your income is above these thresholds.

Capital Gains Tax in Australia: The Full Picture

Capital Gains Tax (CGT) is not a standalone tax in Australia — it is income tax applied to profits from selling assets such as shares, property, cryptocurrency, and managed funds. The gain is added to your taxable income in the year you sell and taxed at your marginal rate.

The 50% CGT Discount

If you hold an asset for more than 12 months before selling, the ATO allows you to discount the capital gain by 50% before adding it to your taxable income. This is one of the most valuable concessions in the Australian tax system.

Example: You bought shares for $40,000, sold two years later for $80,000. Capital gain: $40,000. After the 50% discount, only $20,000 is added to taxable income. At 34.5% marginal rate: $6,900 in CGT — not $13,800. Selling within 12 months would have cost $13,800. Timing your asset sales past the 12-month mark can literally halve your CGT bill.

Capital Gains Tax on Shares

When you sell Australian or international shares, the gain or loss is a CGT event. You can use capital losses from other assets in the same year (or carried forward from prior years) to offset gains. Capital losses cannot be applied against ordinary income — only capital gains. Dividends from Australian companies often come with franking credits — a tax credit representing company tax already paid — which can offset your income tax bill.

Capital Gains Tax on Cryptocurrency

The ATO treats cryptocurrency as a CGT asset, not currency. Selling, trading, swapping, or spending crypto can trigger a CGT event. The 50% discount applies if you held the coin for more than 12 months. Swapping one cryptocurrency for another (e.g. BTC to ETH) is a taxable CGT event at the time of the swap. Keeping detailed records of acquisition costs and disposal dates for every transaction is essential.

Main Residence Exemption (Your Own Home)

Your principal place of residence is generally exempt from CGT. If you lived in the property for the entire ownership period, never rented it out, and never used it for income-producing purposes, you pay no CGT on the sale. Partial exemptions apply if you rented out part of your home or converted it to a rental. The 6-year rule can protect you from CGT if you move out and rent temporarily — provided you do not claim another property as your main residence during that period.

Work-Related Deductions: What You Can Actually Claim

Deductions subtract costs from your taxable income, reducing the tax you pay. The ATO requires that you actually incurred the expense, it must be directly related to earning your income, and you must have a record to prove it.

The Three Golden Rules for Deductions

• You must have spent the money yourself and not been reimbursed
• The expense must directly relate to your work income — not a private or capital expense
• You must be able to prove it with a receipt, invoice, or bank statement

Common Deductible Work Expenses

Home office costs: Use the ATO's fixed rate method (67 cents per hour worked from home) or the actual cost method. The fixed rate covers electricity, internet, phone, and consumables.

Work vehicles and travel: If you use your own car for work purposes (not commuting), claim using the cents-per-kilometre method (88 cents per km for FY 2026-27, up to 5,000 km) or the logbook method for higher-use vehicles.

Education and self-education: Courses, textbooks, and professional development directly relevant to your current role are deductible. General education to enter a new field is not.

Tools, equipment, and technology: Laptops, phones, software subscriptions, and work tools can be claimed in proportion to work use. Items under $300 can be written off immediately; larger items are depreciated over their effective life.

Professional fees, subscriptions, and uniforms: Union fees, professional association memberships, occupation-specific clothing, and tax agent fees are all deductible. Generic clothing you could wear anywhere is not.

The ATO's Crackdown Areas

The ATO uses data matching to flag unusual deduction claims. Work-from-home claims, work-related car expenses, and clothing deductions are consistently targeted for audit. Claiming personal expenses as work-related is fraud, not tax planning — penalties can include interest charges and, in serious cases, prosecution.

HECS-HELP Repayments: When They Kick In

HECS-HELP repayments are not a tax deduction — they come out of your after-tax income via the tax system. Repayments are mandatory once your Repayment Income exceeds the minimum threshold. For FY 2026-27:

HECS-HELP compulsory repayment rates — FY 2026-27

Repayment Income	Repayment Rate
Below $54,435	Nil
$54,435 – $62,999	1.0%
$63,000 – $70,999	2.0%
$71,000 – $80,999	2.5%
$81,000 – $91,999	3.0%
$92,000 – $107,999	3.5%
$108,000 and above	Rates escalate to 10%

HECS debt is indexed to CPI each year (on 1 June), so it grows if you are not repaying it. Use the CalcPhi HECS Repayment Calculator to estimate how long it will take to pay down your student debt.

Superannuation Tax: What Happens Inside Your Super Fund

Concessional (pre-tax) contributions — including your employer's compulsory 12% Super Guarantee and any salary sacrifice contributions — are taxed at 15% inside the fund. For most working Australians, that is far below their marginal rate, making every dollar of salary sacrifice genuinely tax-efficient.

Non-concessional (after-tax) contributions are not taxed going in and grow tax-free inside the fund. The annual concessional contribution cap for FY 2026-27 is $32,500. If you have not used your full concessional cap in prior years, you may be eligible to carry forward unused amounts. Investment earnings inside a super fund are taxed at just 15% in accumulation phase, and 0% in pension phase once you retire.

Rental Income and Negative Gearing

All rental income is assessable income and must be declared on your tax return. In return, you can deduct all expenses related to earning that rental income — interest on the loan, property management fees, council rates, insurance, repairs and maintenance, and depreciation on the building and fittings.

Negative gearing occurs when your total rental expenses exceed your rental income. The resulting net rental loss is deductible against your other income (such as your salary), reducing your overall taxable income. For example: your rental property generates $30,000 in annual rent but costs $42,000 to hold. The $12,000 loss reduces your taxable income. At a 34.5% marginal rate, that saves $4,140 in tax — but you still have a $7,860 real cash loss. Negative gearing is a tax strategy, not a profit strategy on its own.

Lodging Your Tax Return

The Australian tax year runs from 1 July to 30 June. If you lodge your own return via myTax (the ATO's online portal), the deadline is 31 October. If you use a registered tax agent, you may have until 15 May of the following year, provided you are on the agent's books before the October deadline.

Most salaried employees will find their income and employer super details are pre-filled by the ATO once their employer submits Single Touch Payroll data. You are responsible for adding any income the ATO does not know about — rental income, freelance earnings, capital gains, and investment income.

Frequently Asked Questions

• What is the tax-free threshold in Australia for FY 2026-27?

  The tax-free threshold is $18,200. This means you pay no income tax on the first $18,200 you earn. If you earn less than this in a financial year, you can claim the threshold when starting a job and your employer will not withhold tax from your pay. Note that the Medicare levy applies from a lower income threshold.

• Do I pay CGT on shares I held for more than a year?

  Yes, you do pay CGT on the gain — but you receive the 50% CGT discount, meaning only half the gain is added to your taxable income. A $30,000 gain on shares held for 18 months adds only $15,000 to your taxable income. Capital losses from other assets in the same year (or carried forward) can further reduce this amount.

• How does the Medicare Levy Surcharge work in 2026-27?

  If your income exceeds $93,000 as a single (or $186,000 as a family) and you do not hold an eligible private hospital insurance policy, you pay an extra 1%–1.5% Medicare Levy Surcharge on top of the standard 2% Medicare levy. Holding a hospital cover policy that meets ATO requirements exempts you from the surcharge and is often cheaper than paying it.

• Can I claim my home office as a deduction if I work from home?

  Yes. The ATO's revised fixed rate method allows you to claim 67 cents per hour worked from home, covering electricity, internet, phone calls, and stationery. You need to keep a log showing the hours you worked from home. Alternatively, you can use the actual cost method if your real expenses exceed what the fixed rate provides.

• When do HECS-HELP repayments start?

  Compulsory HECS-HELP repayments begin when your repayment income exceeds $54,435 in FY 2026-27. At that threshold the rate is 1% of your total income. Your employer withholds the repayment amount from your pay alongside PAYG tax — check that you have ticked the HELP debt box on your Tax File Number declaration.

• What records do I need to keep for a tax deduction?

  For most deductions, you need a receipt or invoice showing the supplier, the date, the amount, and the nature of the expense. For car expenses under the logbook method, you need a logbook covering a representative 12-week period. Records must be kept for at least five years from the date you lodge your return.
