This guide helps you work out your Australian income tax for 2026–27 — use a quick online check if you want speed, or follow the manual steps if you prefer to do the sums yourself. Below is a quick-reference summary, the core resident tax brackets for 2026–27, the main offsets and levies that usually matter, and the ATO URLs you’ll need to check detailed thresholds and debts.

Quick reference

Here’s the short cheat‑sheet before we get into the steps. Note these figures — you'll be referring to them as you calculate.

  • 2026–27 resident tax brackets: 0 – $18,200: 0%; $18,201–$45,000: 19%; $45,001–$200,000: 30%; $200,001+: 45%.
  • Medicare levy: normally 2% of taxable income. See ATO page: https://www.ato.gov.au/Individuals/Medicare-and-private-health-insurance/Medicare-levy/
  • Common offsets: Low Income Tax Offset (LITO) — reduces tax for low earners (check ATO for current max amounts).
  • HELP/HECS repayments: compulsory repayments are income‑contingent. Use ATO calculator: https://www.ato.gov.au/calculators-and-tools/
  • Key ATO pages: tax rates & PAYG withholding calculator: https://www.ato.gov.au/rates/individual-income-tax-rates/ and https://www.ato.gov.au/calculators-and-tools/tax-withheld-calculator/

Why use an income tax 2026–27 calculator?

Stage 3 tax cuts took effect on 1 July 2024; make sure your 2026–27 calculations reflect those changes. For 2026–27 you need a calculator that uses the updated brackets above. A good calculator tells you expected tax withheld, your likely end‑of‑year bill or refund, and the effect of the Medicare levy, offsets and HELP/HECS debts. It’s handy for pay negotiations, budgeting and planning salary packaging.

Different calculators do different jobs: some spit out a quick PAYG estimate, while others let you enter deductions, rental income, capital gains and the private health surcharge for a fuller lodgement picture. Use a simple online tool for a quick check and a more detailed calculator or manual method when you’ve got deductions, business income, or family tax issues.

Prerequisites

Gather the items below first — that'll save time and cut down on errors.

  • Start with your gross annual income: salary, bonuses and allowances, plus other assessable amounts like interest, dividends and rent.
  • Amounts already withheld via PAYG — check recent payslips and your employer income statement available through myGov/ATO.
  • Records of deductible expenses — work‑related expenses, vehicle logs, home office costs, self‑education receipts, gifts to deductible charities (DGR) and tax agent fees.
  • Information on reportable fringe benefits, employer super contributions and any reportable employer super salary sacrifice amounts.
  • HELP/HECS and other study debt balances — and the year’s repayment threshold (use the ATO HELP repayment thresholds page).
  • Your residency status for tax purposes — resident or non‑resident. Non‑residents don’t get the tax‑free threshold and use different rates. ATO residency tests: https://www.ato.gov.au/individuals/international-tax-for-individuals/residency/
  • Private health insurance details if you may be liable for the Medicare levy surcharge (policy dates and singles/family income).

Step-by-step: manual income tax 2026-27 calculator

Sure, follow these numbered steps to calculate tax for the 2026–27 year in AUD. You can do this with a pen, a calculator or in Excel/Google Sheets. At the end there’s a worked example.

  1. Confirm residency. Australian tax rates above apply to tax residents. Non‑residents are taxed differently and don’t get the tax‑free threshold. Use the ATO residency tests at https://www.ato.gov.au/ to confirm your status.
  2. Assemble assessable income. Add up all assessable items: gross salary, wages, bonuses, allowances, bank interest, franked/unfranked dividends, rental income, business income and any capital gains for the year. Record the total — this is your assessable income.
  3. Subtract allowable deductions to get taxable income. Common deductions are work‑related expenses, car and travel costs where allowed, home office expenses, tools and equipment, union fees, tax preparation fees, and donations to DGR charities. For rental property owners include interest, repairs (not capital improvements) and property management fees. The result is taxable income. Keep receipts and logbooks for substantiation.
  4. Apply the 2026–27 resident tax brackets. Use the following bands to compute your base tax (tax on taxable income, before levies and offsets):
    • 0 – $18,200: nil
    • $18,201 – $45,000: 19% on the portion over $18,200
    • $45,001 – $200,000: 30% on the portion over $45,000
    • $200,001 and over: 45% on the portion over $200,000

    Work out the tax due in each bracket and add those amounts together. That sum is your income tax before the Medicare levy and offsets.

  5. Add the Medicare levy (normally 2%). Estimate the Medicare levy as 2% of your taxable income, then check official guidance for any low‑income exemptions. Some low‑income earners are exempt or pay a reduced levy; families and seniors may have different thresholds. See ATO Medicare levy page: https://www.ato.gov.au/Individuals/Medicare-and-private-health-insurance/Medicare-levy/
  6. Factor in the Medicare levy surcharge (MLS) if relevant. If you or your family don't hold appropriate private hospital cover and your income exceeds the MLS thresholds, you may pay an extra 1%–1.5% on top of the Medicare levy. Check your family income and policy dates against the ATO rules at: https://www.ato.gov.au/Individuals/Medicare-and-private-health-insurance/Private-health-insurance-rebate/ and your insurer records.
  7. Apply offsets and rebates. Common offsets include the Low Income Tax Offset (LITO) — it reduces tax payable for low earners. There are also specific offsets for seniors, pensioners and zone/home office cases. Subtract eligible offsets from the base tax + Medicare levy to get your final tax payable before HELP and other repayments.
  8. Include HELP/HECS and other study debt repayments. If you have a HELP/HECS debt, compulsory repayments are based on your repayment income and rounded percentages (rates rise with income). Add the compulsory repayment amount to your tax payable. Use the ATO HELP repayment rate table or calculator to get the exact percentage for 2026–27: https://www.ato.gov.au/
  9. Compare to PAYG withheld. Subtract the total amount your employer has already withheld (PAYG on your payslips or income statement). If PAYG withheld is greater than tax payable, you’ll likely get a refund. If it’s lower, you’ll owe the difference when you lodge your tax return.
  10. Check for instalments or other liabilities. If you’re on PAYG instalments, include any instalment amounts credited to your tax account. Also account for any prior year debts or ATO notices on your record.

Worked example

Taxable income: $85,000.

  • 0 – $18,200: $0
  • $18,201 – $45,000 = $26,800 taxed at 19% = $5,092
  • $45,001 – $85,000 = $40,000 taxed at 30% = $12,000
  • Base tax = $5,092 + $12,000 = $17,092
  • Medicare levy (2%) = $1,700
  • Tax before offsets and HELP = $18,792

If PAYG withheld during the year was $16,000, the taxpayer would expect to owe roughly $2,792 at lodgement, before allowing for any offsets, HELP repayments or other credits.

Tips

  • Use the ATO PAYG withholding calculator for a quick check of how much should be withheld per pay: https://www.ato.gov.au/calculators-and-tools/tax-withheld-calculator/.
  • Do a mid‑year check. Run the numbers at least once mid‑year if you’ve had a big pay change, bonus or a change in family situation — this avoids surprises at lodgement.
  • If you have rental property or small business income, do the calculation with and without one‑off deductions to see the effect on tax and cashflow.
  • Keep digital copies of receipts and a simple spreadsheet of expenses. That makes manual calculations and tax agent work much faster.
  • When unsure, get a registered tax agent — especially if you’ve got capital gains, foreign income or complex business losses. Agents can also advise on legal tax planning carried out within the year.

Common mistakes to avoid

  • Using pre‑Stage 3 brackets. Make sure any calculator is updated for the post‑1 July 2024 brackets shown above.
  • Forgetting non‑salary income. Bank interest, dividends, rental and side‑gig income are taxable and often missed when people only look at payslips.
  • Mixing up gross and taxable income. Taxable income is assessable income minus deductions — don’t apply rates to gross without subtracting allowed deductions.
  • Ignoring the Medicare levy and surcharge. They add a material amount — 2% of taxable income is common for most earners.
  • Assuming PAYG withholding equals final tax. Employers use withholding schedules that are estimates — lodgement reconciles actual tax, offsets and debts.
