1 What this calculator does

Calculates Australian income tax using 2024-25 ATO progressive tax brackets, the Low Income Tax Offset (LITO) and optional Medicare levy. Shows total tax, effective rate, take-home pay per year and per week. Supports both resident and non-resident tax scales.

2 Formula & professional reasoning

Tax brackets 2024-25 (resident): $0-$18,200: 0% | $18,201-$45,000: 19% | $45,001-$120,000: 32.5% | $120,001-$180,000: 37% | $180,001+: 45% LITO: $700 for income up to $37,500 | phases out to $0 at $66,667 Medicare levy: 2% of taxable income (standard) Effective rate = Total tax / Gross income x 100

Australia uses a progressive tax system -- each bracket only applies to income within that band, not the total income. The LITO is a non-refundable offset that reduces the tax payable for low to middle income earners. The 2024-25 Stage 3 tax cuts restructured the middle brackets, reducing the 32.5% bracket threshold and removing the 37% rate for most taxpayers. The Medicare levy of 2% funds the public health system and applies to most taxpayers.

3 Worked examples

⚠️ Illustrative example only — not clinical or professional instruction.

Basic
Standard salaried employee at $75,000
Given: Income: $75,000 | Resident | Medicare: standard (2%)
Working: Tax: $5,092 + ($75,000-$45,000) x 0.325 = $5,092 + $9,750 = $14,842 | LITO: $0 (income >$66,667) | Medicare: $75,000 x 0.02 = $1,500 | Total: $16,342
Answer: Tax: $14,842 | Medicare: $1,500 | Total: $16,342 | Effective rate: 21.8% | Take-home: $58,658/yr ($1,128/wk)
💡 The marginal rate is 32.5% but the effective rate is only 21.8% -- because the lower brackets and LITO reduce the overall burden. The effective rate is the meaningful number for budgeting.
Standard
Pay rise impact -- $95,000
Given: Income: $95,000 | Resident | Medicare: 2%
Working: Tax: $5,092 + ($95,000-$45,000) x 0.325 = $5,092 + $16,250 = $21,342 | LITO: $0 | Medicare: $1,900 | Total: $23,242
Answer: Tax: $21,342 | Medicare: $1,900 | Total: $23,242 | Effective rate: 24.5% | Take-home: $71,758/yr ($1,380/wk)
💡 Moving from $75K to $95K adds $20,000 gross. The extra $20,000 is taxed at 32.5% + 2% Medicare = 34.5%, adding $6,900 in tax and delivering $13,100 extra take-home. The marginal rate of 34.5% is the cost of the extra income.
Advanced
High income -- $200,000
Given: Income: $200,000 | Resident | Medicare: 2%
Working: Tax: $51,667 + ($200,000-$180,000) x 0.45 = $51,667 + $9,000 = $60,667 | LITO: $0 | Medicare: $4,000 | Total: $64,667
Answer: Tax: $60,667 | Medicare: $4,000 | Total: $64,667 | Effective rate: 32.3% | Take-home: $135,333/yr
💡 Even at $200,000 the effective rate is 32.3% -- well below the 47% top marginal rate. The progressive system means the highest rate only applies to income above $180,000.

4 Sanity check

2024-25 tax brackets (resident)
$0-$18,200: nil | $18,201-$45,000: 19% | $45,001-$120,000: 32.5% | $120,001-$180,000: 37% | $180,001+: 45%
Stage 3 tax cuts from 1 July 2024 restructured these brackets.
Effective vs marginal rate
Marginal rate: the rate on the next dollar earned | Effective rate: total tax as a % of total income
Always budget using the effective rate. The marginal rate is only relevant for deciding whether extra income or deductions are worthwhile.
LITO reduces tax for lower incomes
$700 offset up to $37,500 income | Phases out to $0 at $66,667
This calculator excludes
HECS/HELP repayments | Investment income offsets | Work-related deductions | Private health insurance rebate/surcharge

5 Common errors

ErrorCauseConsequenceFix
Confusing marginal rate with effective rate for budgeting Thinking all income is taxed at the marginal rate Take-home pay significantly underestimated -- financial plans too conservative The marginal rate only applies to income within the top bracket. Use the effective rate (total tax divided by total income) for household budgeting.
Not including the Medicare levy in take-home calculations Forgetting the 2% Medicare levy Take-home pay overestimated by approximately 2% Add 2% Medicare levy to the income tax for resident taxpayers. At $80,000, the Medicare levy is $1,600 -- a meaningful amount in a budget.
Using pre-Stage 3 brackets for 2024-25 planning Using older tax tables Tax estimates significantly wrong -- Stage 3 changes reduced tax for incomes between $45K-$180K Use 2024-25 rates: 32.5% applies from $45,001 to $120,000 (expanded from the previous bracket end of $90,000).
Calculating tax on the gross salary without considering pre-tax deductions Not accounting for salary sacrifice or superannuation pre-tax contributions Tax overstated if pre-tax salary sacrifice reduces taxable income Salary sacrifice (e.g. extra super contributions) reduces taxable income before the tax calculation. If salary sacrificing, enter the after-sacrifice salary, not the full gross package.
