If you’ve ever stared at your payslip wondering why theATO takes what it does, you’re not alone — Australia’s tax system uses six marginal brackets, a Medicare levy surcharge tied to your income, and offsets that phase out at unpredictable points. Running your numbers through a reliable tax calculator before lodgment season hits can spare you a surprise refund bill. Below is a complete guide to the official government tools, how the brackets actually work, and which commercial calculators do the job well.

After tax calculator Australia
An after-tax calculator estimates your take-home pay by starting with gross income and subtracting the tax that would be withheld under current ATO rates. The key thing these tools do is convert annual ATO marginal brackets into either fortnightly or weekly amounts, so you can see exactly how much lands in your bank each pay cycle.
How after tax calculators work
After-tax calculators run your gross income through the ATO’s progressive bracket system. They apply the tax-free threshold first, then calculate marginal tax on each portion of income above $18,200. The Moneysmart Income Tax Calculator, a government-backed tool, shows take-home pay by excluding offsets — meaning the result is typically higher than what you’ll actually owe, since offsets like the Low Income Tax Offset reduce your final bill at tax time.
The ATO explicitly states its calculators provide estimates only, and they do not account for all offsets that may apply to your situation — so treat the output as a starting point, not your final tax liability.

Tax brackets Australia
Australia uses a progressive tax system with six marginal brackets for residents. The stage 3 tax cuts that took effect on 1 July 2024 simplified the lower end of the scale by merging the old 19% and 32.5% brackets into a new 16% bracket, which now runs from $18,201 to $45,000.
Current income tax brackets
The 2024-25 resident tax brackets are confirmed by the ATO for the period ending 30 June 2025, with identical rates applying for 2025-26 per multiple independent sources.
These thresholds show how progressively each dollar above $18,200 gets taxed at higher marginal rates as income rises.
| Income range | Marginal rate | Base tax at lower bound |
|---|---|---|
| $0 – $18,200 | 0% | Nil |
| $18,201 – $45,000 | 16% | Nil |
| $45,001 – $135,000 | 30% | $4,288 |
| $135,001 – $190,000 | 37% | $31,288 |
| $190,001+ | 45% | $51,638 |
The tax-free threshold of $18,200 means no tax is owed on the first $18,200 of income for Australian residents. For income above this amount, each dollar is taxed at the marginal rate applying to the bracket it falls into.
How brackets affect calculations
Because Australia uses marginal rates, not a flat percentage, each calculator must segment your income across the applicable brackets. For example, a $60,000 annual salary has $18,200 taxed at 0%, the next $26,800 at 16%, and the remaining $15,000 at 30% — with each portion contributing to your total tax bill separately.
The Low Income Tax Offset (LITO) provides a maximum rebate of $700 for income at or below $37,500 in 2025-26, phasing out by $1.50 per dollar above $45,000 up to $66,667 — a detail many basic calculators do not apply automatically.
Tax in Australia for foreigners
Non-residents for tax purposes face a different bracket structure that starts at 32.5% from the first dollar — there is no tax-free threshold for foreign residents. This makes after-tax calculators designed for residents significantly inaccurate if you are working in Australia on a temporary visa.
Tax rules for non-residents
Foreign residents are taxed at 32.5% on income up to $135,000, then 37% up to $190,000, and 45% above that — with no $18,200 offset applying. If you are uncertain about your residency status for tax purposes, the ATO has a tax residency tool that applies the statutory tests.
Temporary residents on subclass 482 or 457 visas often qualify as foreign residents for tax purposes — meaning their effective tax rate starts at 32.5% on all income, not 16% after a tax-free threshold.
Foreigner-specific calculators
- The ATO Simple Tax Calculator allows selection of non-resident status, applying foreign resident rates automatically
- Some commercial tools require manual input to simulate foreign resident brackets, which can introduce errors if the user does not know the non-resident thresholds
- H&R Block’s calculator includes residency status as an input option for more accurate 2025 refund estimates
PAYG calculator
PAYG (Pay As You Go) withholding is the system through which employers deduct tax from your salary each pay period, based on the rates the ATO publishes in PAYG tax tables. A PAYG calculator estimates the withholding amount for each pay cycle so you can check whether your employer is deducting the right amount.
PAYG withholding explained
PAYG withholding schedules convert the annual tax brackets into either weekly, fortnightly, or monthly amounts. If your income is consistent across the year, your PAYG withholding should roughly equal your annual tax divided by the number of pay periods. The William Buck tax withheld calculator helps verify this conversion for specific salary figures.
- Weekly withholding uses ATO’s schedule 2 for weekly payers
- PAYG scales account for tax-free threshold spread across the year
- Excess withholding results in a tax refund at lodgment; insufficient withholding can result in a tax bill
Using PAYG tools
To use a PAYG calculator effectively, input your gross annual salary, select your pay frequency (weekly, fortnightly, or monthly), and enter any allowances or reportable fringe benefits — these affect the withholding rate the ATO schedule prescribes.
If you have multiple jobs or receive a lump sum payment such as unused leave on termination, standard PAYG calculators may underestimate your withholding because they assume a consistent single income source throughout the year.
Weekly tax calculator
A weekly tax calculator converts annual ATO brackets into weekly amounts by dividing each bracket threshold by 52. This is particularly useful for casual workers, part-time employees, or anyone paid weekly who wants to budget accurately based on their expected take-home pay.
Weekly vs annual calculations
The annual tax brackets divide into approximate weekly equivalents: $18,200 ÷ 52 = roughly $350 per week tax-free, the 16% bracket runs from approximately $350 to $865 weekly, and the 30% bracket starts at around $865 per week. These conversions let weekly payers track their marginal rate position in real time.
- Weekly calculations apply each week’s income against the cumulative threshold position
- Seasonal variations (overtime bonuses, leave loading) can shift a worker into a higher bracket for one week only
- The ATO tax withheld calculator handles variable pay scenarios better than simple flat-rate tools
Best weekly tools
Most of the major calculators (ATO Simple Tax Calculator, Moneysmart, H&R Block) allow pay frequency selection that breaks results into weekly, fortnightly, or monthly figures. Industry Super’s tax calculator specifically supports FY2024-2025 and 2025-2026 calculations with weekly output options.
Tool comparison: which tax calculator should you use?
Three tiers of tools serve different needs: official government tools for authoritative rate data, government-backed tools for take-home pay estimates, and commercial tools for refund projections and specialised scenarios.
This comparison evaluates seven calculators across eight criteria to help you choose the right tool for your situation.
| Calculator | Source type | Current rates | Offset handling | Non-resident | Weekly output | PAYG | Refund est. |
|---|---|---|---|---|---|---|---|
| ATO Simple Tax Calculator | Government (Tier 1) | Yes | Not included | Yes | No | Partial | No |
| Moneysmart Income Tax Calculator | Government (Tier 1) | Yes | Not included | Limited | No | No | No |
| H&R Block Tax Calculator | Commercial (Tier 2) | Yes | Included (est.) | Yes | Yes | Yes | Yes |
| Talent.com Tax Calculator | Commercial (Tier 3) | 2026 focus | Not included | Limited | Yes | No | Partial |
| eTax Calculator | Commercial (Tier 2) | Yes | Included (est.) | Yes | Yes | Yes | Yes |
| Money.com.au Pay Calculator | Commercial (Tier 2) | Yes | Not included | Limited | Yes | Yes | No |
| Industry Super Tax Calculator | Industry (Tier 2) | Yes | Not included | Limited | Yes | No | No |
The pattern across these tools is clear: Tier 1 government sources prioritise rate accuracy and transparency but omit refund estimates; Tier 2 commercial sources add convenience features but vary in how completely they handle offsets and non-resident scenarios.
Step-by-step: using the ATO Simple Tax Calculator
The ATO Simple Tax Calculator is the most authoritative option for estimating tax on taxable income, and it requires no account creation. Follow these steps to get a result for the current 2024-25 income year.
- Select the income year — Choose 2024-25 from the dropdown. The calculator currently covers 2013-14 to 2024-25 as its most recent year, with 2025-26 data expected in future updates.
- Enter your residency status — Select “Australian resident” or “Foreign resident” as this changes the applicable brackets entirely. This step is critical for anyone on temporary visas.
- Input taxable income — Enter your gross income minus any exempt income components. Do not include the tax-free threshold here; the calculator applies it automatically for residents.
- Review the result — The output shows tax on taxable income before offsets, as the ATO notes this is the tax on taxable income before offsets. The figure does not include Medicare levy or any offsets.
- Cross-check with a commercial tool — Run the same income through H&R Block or eTax to compare, noting any differences likely stem from offset handling.
The ATO Simple Tax Calculator is authoritative but deliberately conservative — it tells you the tax on your taxable income before applying offsets like LITO, depreciation, or charitable donations. Use it as the rate anchor, then add offsets manually or via a commercial tool for a complete picture.

Frequently asked questions
Is the ATO tax calculator free?
Yes, the ATO Simple Tax Calculator is completely free and available directly at ato.gov.au without any login or account creation. The Moneysmart.gov.au Income Tax Calculator is also free and government-backed.
Can I use tax calculators for 2026?
Talent.com offers a 2026 tax year calculator, but the ATO Simple Tax Calculator currently tops out at 2024-25. The 2025-26 tax tables have been published by the ATO covering 1 July 2025 to 23 September 2025, so some commercial tools may incorporate these ahead of official ATO updates.
Do tax calculators account for offsets?
The ATO Simple Tax Calculator explicitly does not include offsets — it calculates tax on taxable income before offsets. Moneysmart similarly excludes rebates and offsets. Commercial tools like H&R Block and eTax include estimated offset calculations, though these are approximations.
What income types are supported?
Standard calculators handle salary, wages, and superannuation income. Some tools support interest, dividends, rental income, and business income separately. For complex portfolios with multiple income streams, a tax agent or specialised software is recommended.
How accurate are third-party tax calculators?
Third-party calculators using current ATO rate data should be accurate to within a few dollars for simple income scenarios. Accuracy decreases for complex situations involving offsets, multiple income streams, or fringe benefits. The ATO rate source is authoritative; the offset handling varies by tool.
Are there mobile tax calculator apps?
The ATO offers the ATO app for iOS and Android, which includes withholding and superannuation calculators. Moneysmart also has a mobile-friendly web calculator. Most commercial tools like H&R Block and eTax offer mobile-responsive interfaces accessible via smartphone browsers.
What if my income changes mid-year?
If you receive a pay rise, bonus, or change employment mid-year, use a PAYG withholding calculator to check whether your new employer should be deducting more tax. Insufficient withholding across the full year typically results in a tax bill at lodgment, while over-withholding generates a refund.
What are the Medicare levy surcharge thresholds?
The Medicare levy surcharge applies at 1% for singles earning above $101,000 (or couples above $202,000 combined) who do not have private hospital cover. Tiers increase to 1.25% and 1.5% at higher income levels. The ATO Simple Tax Calculator does not include this surcharge — use a dedicated Medicare levy calculator or a commercial tool that incorporates it.
For Australian workers, the choice of tax calculator hinges on what you need it to do: verify withholding accuracy, estimate a refund, or plan for a future income level. The ATO Simple Tax Calculator remains the authoritative baseline for rates and brackets, while commercial tools add the offset handling and convenience features that turn raw numbers into actionable take-home pay estimates.
