2017-2018 FY Tax Calculator
Introduction & Importance of the 2017-2018 FY Tax Calculator
The 2017-2018 financial year (1 July 2017 to 30 June 2018) introduced several important changes to Australia’s tax system that continue to impact taxpayers today.

Formula & Methodology Behind the 2017-2018 Tax Calculator
Taxable Income Calculation
The first step in the calculation process is determining your taxable income:
Taxable Income = Total Income – Total Deductions
Income Tax Calculation
The 2017-2018 financial year used the following tax rates for Australian residents:
| Taxable Income | Tax on This Income | Effective Tax Rate |
|---|---|---|
| $0 – $18,200 | Nil | 0% |
| $18,201 – $37,000 | 19c for each $1 over $18,200 | 19% |
| $37,001 – $87,000 | $3,572 plus 32.5c for each $1 over $37,000 | 21.9% – 32.5% |
| $87,001 – $180,000 | $19,822 plus 37c for each $1 over $87,000 | 32.5% – 37% |
| $180,001 and over | $54,232 plus 45c for each $1 over $180,000 | 45% |
For non-residents, the tax rates were different:
| Taxable Income | Tax Rate |
|---|---|
| $0 – $87,000 | 32.5% |
| $87,001 – $180,000 | $28,275 plus 37c for each $1 over $87,000 |
| $180,001 and over | $62,625 plus 45c for each $1 over $180,000 |
Medicare Levy Calculation
The Medicare levy for 2017-2018 was calculated as follows:
- Standard rate: 2% of taxable income
- Reduced rate: 1% if taxable income was between $21,655 and $27,068 (singles) or $36,541 and $45,677 (families)
- No levy: If taxable income was below $21,655 (singles) or $36,541 (families)
- Additional 1% levy for high-income earners without private hospital cover (income over $90,000 singles or $180,000 families)
HECS/HELP Repayment Calculation
Repayment thresholds and rates for 2017-2018 were:
| Repayment Income | Repayment Rate |
|---|---|
| Below $55,874 | 0% |
| $55,874 – $62,903 | 4% |
| $62,904 – $69,933 | 4.5% |
| $69,934 – $76,962 | 5% |
| $76,963 – $83,991 | 5.5% |
| $83,992 – $91,021 | 6% |
| $91,022 – $98,050 | 6.5% |
| $98,051 – $105,079 | 7% |
| $105,080 – $112,108 | 7.5% |
| $112,109 and above | 8% |
Low Income Tax Offset (LITO)
For 2017-2018, the LITO provided tax relief for low-income earners:
- Maximum offset: $445
- Phase-out rate: 1.5 cents per dollar over $37,000
- Fully phased out at: $66,667
Low and Middle Income Tax Offset (LMITO)
Introduced in the 2018-2019 budget but backdated to include 2017-2018, the LMITO provided additional relief:
- Maximum offset: $200 (for incomes $37,000 – $48,000)
- Phase-out rate: 6 cents per dollar between $48,000 and $90,000
- Base amount: $200 (for incomes below $37,000)
Real-World Examples: 2017-2018 Tax Calculations
Case Study 1: Full-Time Employee with Standard Deductions
Scenario: Sarah is a marketing manager earning $85,000 in 2017-2018. She has $2,500 in work-related deductions and $300 in charitable donations. She’s an Australian resident with no HECS debt and private health insurance.
Calculation:
- Taxable Income: $85,000 – $2,800 = $82,200
- Income Tax: $19,822 + 37% of ($82,200 – $87,000) = $17,524.60
- Medicare Levy: 2% of $82,200 = $1,644 (but reduced to $822 due to private health insurance rebate)
- LITO: $0 (income above phase-out threshold)
- LMITO: $200 (full offset as income is below $90,000)
- Net Tax: $17,524.60 + $822 – $200 = $18,146.60
- Net Income: $85,000 – $18,146.60 = $66,853.40
Case Study 2: Part-Time Worker with HECS Debt
Scenario: James is a part-time university tutor earning $45,000 in 2017-2018. He has $1,200 in deductions and a $20,000 HECS debt. He’s an Australian resident with no private health insurance.
Calculation:
- Taxable Income: $45,000 – $1,200 = $43,800
- Income Tax: $3,572 + 32.5% of ($43,800 – $37,000) = $5,657
- Medicare Levy: 2% of $43,800 = $876
- LITO: $445 – (1.5% of ($43,800 – $37,000)) = $368.50
- LMITO: $200 (full offset)
- HECS Repayment: 4% of $43,800 = $1,752
- Net Tax: $5,657 + $876 – $368.50 – $200 + $1,752 = $7,716.50
- Net Income: $45,000 – $7,716.50 = $37,283.50
Case Study 3: High-Income Earner with Investment Properties
Scenario: Michael is a senior executive earning $150,000 in salary plus $20,000 in rental income. He has $30,000 in deductions (including $15,000 for property expenses) and a $40,000 HECS debt. He’s an Australian resident with private health insurance.
Calculation:
- Taxable Income: ($150,000 + $20,000) – $30,000 = $140,000
- Income Tax: $54,232 + 45% of ($140,000 – $180,000) = $54,232 (no additional tax as income is below $180,000)
- Wait – correction needed. For $140,000:
- Income Tax: $19,822 + 37% of ($140,000 – $87,000) = $19,822 + $19,990 = $39,812
- Medicare Levy: 2% of $140,000 = $2,800 (but reduced to $1,400 due to private health insurance rebate)
- LITO: $0 (income above phase-out threshold)
- LMITO: $0 (income above $90,000 phase-out threshold)
- HECS Repayment: 8% of $140,000 = $11,200
- Net Tax: $39,812 + $1,400 + $11,200 = $52,412
- Net Income: $170,000 – $52,412 = $117,588

Amending Prior Year Returns
If you discover errors in your 2017-2018 return, you can still amend it:
- Most amendments can be made through myTax or your tax agent
- You generally have 2 years from the date of your original assessment to request an amendment

How does this calculator handle the temporary budget repair levy that was in place in previous years?
The temporary budget repair levy was a 2% surcharge on taxable incomes over $180,000 that applied from 1 July 2014 to 30 June 2017. For the 2017-2018 financial year:
- The levy did not apply in 2017-2018 as it was removed from 1 July 2017
- This calculator automatically excludes the levy from all calculations
- If you’re comparing with previous years (2014-2015 to 2016-2017), you would need to add 2% to the tax payable for income over $180,000
- The removal of this levy effectively reduced the top marginal tax rate from 49% to 47% (including Medicare levy) for high-income earners
For example, someone earning $200,000 in:
- 2016-2017: Would pay $54,232 + 47% of ($200,000 – $180,000) + 2% levy on $20,000 = $63,232 + $400 = $63,632
- 2017-2018: Would pay $54,232 + 45% of ($200,000 – $180,000) = $54,232 + $9,000 = $63,232
The removal of this levy was part of the government’s plan to provide tax relief to high-income earners while maintaining progressive taxation through the existing brackets.
