Taxing Wages 2026

Australia (2024-2025 Income tax year)

Abstract

This chapter includes data on the income taxes paid by workers, their social security contributions, the family benefits they receive in the form of cash transfers as well as the social security contributions and payroll taxes paid by their employers. Results reported include the marginal and average tax burden for eight different family types.

Methodological information is available for personal income tax systems, compulsory social security contributions to schemes operated within the government sector, universal cash transfers as well as recent changes in the tax/benefit system. The methodology also includes the parameter values and tax equations underlying the data.

 

 

The national currency is the Australian dollar (AUD). For the 2024-2025 income tax year AUD 1.55 was equal to USD 1. The average full-time worker earned AUD 108 674 in 2024-2025.

Personal income tax system

Federal income tax

Tax unit

Members of a family unit are taxed separately. However, individual eligibility for some tax offsets, as well as liability for some taxes, levies and surcharges, are at least partially dependent on the circumstances of other members of an individual’s household.

Tax allowances and credits

Standard tax reliefs

• Basic reliefs: Income earned up to AUD 18 200 by resident taxpayers is subject to tax at a zero rate.

• Standard marital status reliefs: No relief available.

• Relief(s) for children: See Section 4.2 for more detail on transfers related to dependent children.

• Relief for social security contributions and other taxes: No such contributions are levied.

• Reliefs for low income earners: A tax offset worth a maximum of AUD 700 is available for low income earners called the Low Income Tax Offset. Taxpayers whose taxable income was less than or equal to AUD 37 500 in 2024-2025 are eligible to receive the full amount of the offset. Between taxable income ranges of AUD 37 501 and AUD 45 000, the offset is reduced by AUD 0.05 for every AUD 1 by which a taxpayer’s taxable income exceeds AUD 37 500. When taxable income exceeds AUD 45 000, the offset is further reduced by 0.015 AUD for every AUD 1. The offset is no longer available once a taxpayer’s taxable income exceeds AUD 66 667.

• Relief for mature age workers: No relief available.

• Relief for recipients of certain social security benefits: The Beneficiary Tax Offset is available for those who receive certain taxable social security benefits called ‘rebatable benefits’. It ensures that a person who is wholly or mainly dependent on rebatable benefits, and does not have any other taxable income, is not liable for income tax. The amount of the Beneficiary Tax Offset available to an individual is determined by the total amount of the rebatable benefit(s) they receive in an income year.

• Relief for taxpayers who maintain a dependant who is genuinely unable to work: A taxpayer who maintains a dependant who is genuinely unable to work due to invalidity or carer obligations may be eligible for the Dependent (Invalid and Carer) Tax Offset. This tax offset is worth a maximum of AUD 3 300 in 2024-2025. To qualify for the offset in 2024-2025, the combined adjusted taxable income of the taxpayer and their spouse (where one exists, and they are not the person being cared for) should not exceed AUD 117 194. If the taxpayer is caring for their spouse, the threshold applies to their income only. The amount of offset that may be received is reduced by AUD 0.25 for every AUD 1 by which the dependant's adjusted taxable income exceeds AUD 282 and is no longer available once the dependant’s adjusted taxable income exceeds AUD 13 482. This offset is not included in the Taxing Wages model.

• Relief for pensioners and seniors: The Seniors and Pensioners Tax Offset (SAPTO) is available to recipients of taxable Government Pensions, including the Age Pension. The SAPTO is also available to Australians who meet all of the Age Pension eligibility criteria except the income and/or asset tests. The SAPTO is worth up to AUD 2 230 for a single taxpayer, up to AUD 1 602 for each member of a senior couple not separated by illness and AUD 2 040 for each member of a senior couple separated by illness. The offset is withdrawn at the rate of AUD 0.125 for every AUD 1 that a recipient’s income exceeds their relevant shade out threshold dependent on their circumstances. For a single taxpayer, the offset is withdrawn from AUD 34 919 and is no longer available once income reaches AUD 52 759. For members of a couple not separated by illness, the offset is withdrawn from a combined income of AUD 61 988 and is no longer available once combined income reaches AUD 87 620.

• Other: No other standard relief available.

Main non-standard tax reliefs applicable to an average worker include:

• Relief for superannuation: Contributions to a low income spouse’s superannuation attract an 18% rebate up to a maximum rebate of AUD 540. The income limit for a low income spouse is AUD 40 000. In 2024-2025, the Low Income Superannuation Tax Offset matches AUD 0.15 for each AUD 1 of concessional contributions from at least AUD 10 up to AUD 500 a year for eligible individuals with annual incomes up to AUD 37 000. In addition in 2024-2025, eligible individuals with incomes not exceeding AUD 60 400 can make non-concessional contributions and receive a co-contribution of 50%, up to a maximum of AUD 500. The co-contribution rate progressively decreases for incomes between AUD 45 400 and AUD 60 400, at a rate of AUD 0.03 per AUD 1 of income above AUD 45 400.

• Relief for private health insurance: For the 2024-2025 income year, there are different rebate amounts depending on age and income. For individuals below 65 years without dependants and with annual income for surcharge purposes below AUD 97 000 the rebate is 24.608% of the cost of cover for eligible private health care for the 2024-2025 income year. The same rebate rates apply for families (couples and individuals with at least one dependent child) below 65 years with annual income for surcharge purposes below AUD 194 000. The threshold is increased by AUD 1 500 for each dependent child after the first. The rebate percentages are reduced for individuals and families with annual incomes above these amounts. The rebate percentages are also higher for individuals and families aged 65 years or more.

• Other non-standard reliefs provided as deductions are:

  • subscriptions paid in respect of membership of a trade, business or professional association or union;

  • charitable contributions of AUD 2 or more to specified funds, authorities and institutions, including public benevolent institutions, approved research institutes for scientific research, building funds for schools conducted by non-profit organisations etc.; and

  • work-related expenses including cost of replacement of tools of trade, cost of provision and of cleaning protective clothing and footwear, travelling between jobs or travelling in the course of employment, and certain expenses related to working from home.

To nominally contribute towards the cost of basic medical and hospital care, a Medicare levy is imposed on the taxable incomes of resident taxpayers. In 2024-2025 the levy is applied at the rate of 2.0% of the taxable income of an individual.

Certain thresholds are applied before the Medicare levy is imposed. For taxpayers aged under Age Pension age in 2024-2025, an individual was not liable for the levy where their taxable income did not exceed AUD 27 222. A taxpayer in a couple or sole parent family who is not receiving Parenting Payment (see section 4.2), does not pay the levy if the taxable family income does not exceed AUD 45 907. Individual senior Australians of Age Pension age were not liable to pay the levy where their taxable income did not exceed AUD 43 020. Pensioner families (including couples and sole parents on Parenting Payment) and senior Australian families of Age Pension age did not become liable to pay any Medicare levy until their combined income in 2024-2025 exceeded AUD 59 886. The thresholds are increased by AUD 4 216 for each dependent child.

Where an individual’s or family’s taxable income exceeds these thresholds, the Medicare levy shades in at a rate of 10% of the excess taxable income over the threshold, until the levy is equal to 2.0% of the individual’s or family’s total taxable income.

Individual taxpayers who had income for surcharge purposes greater than AUD 97 000 in 2024-2025 (or if a couple had a combined income greater than AUD 194 000 plus AUD 1 500 for each dependent child after the first child) but who did not have a complying private health insurance policy, were liable for the Medicare levy surcharge. The surcharge rates are 1%, 1.25% and 1.5% depending on the taxpayer’s income for surcharge purposes above these thresholds. The surcharge rate is applied as a flat rate on their taxable income, reportable fringe benefits and any amount on which family trust distribution tax has been paid. However, the majority of taxpayers with income above the thresholds purchase a complying policy and avoid incurring the surcharge. The surcharge is therefore not included in the Taxing Wages calculations.

State and local income taxes

In Australia, no states or territories levy a tax based on a resident’s income.

Social security contributions

Employees’ contributions

None. There is, however, a Medicare Levy which is based upon taxable income. See Section 1.1.3.

Employers’ contributions

No contributions are collected from employers or employees specifically for pensions, sickness, unemployment or work injury benefits, family allowances or other benefits.

Part of Australia’s retirement income system is the provision of compulsory employer contributions (the Superannuation Guarantee system). In 2024-2025 the Superannuation Guarantee required employers to pay 11.5% on top of employees’ gross ordinary time earnings to an approved superannuation fund. There is also a limit to the Superannuation Guarantee. In each quarter any earnings beyond a threshold are not covered by the Superannuation Guarantee. This threshold is indexed to a measure of average earnings. In the 2024-2025 tax year this threshold was AUD 65 070 per quarter. The Superannuation Guarantee rate will increase to 12% in 2025-26.

These contributions are not reflected in the Taxing Wages calculations because they are not a form of taxation (they are not an unrequited transfer to general government). While employers are legislatively required to make contributions to approved superannuation funds, superannuation funds are private, although subject to regulation. Employers’ contributions are generally made to individual accounts and form part of employees’ personal superannuation assets. Some defined benefit schemes for public sector employees and private defined benefit schemes also exist. The employee may take superannuation benefits as either a lump sum payment or pension on retirement. Accordingly, superannuation contributions are reflected in the Non-Tax Compulsory Payment calculations.

Other taxes

Pay-roll tax

Australian State Governments levy pay-roll taxes on wages, cash or in kind, provided by larger employers to their employees. The rates of pay-roll tax, thresholds and deductions differ between States. In New South Wales, the State with the largest population, the pay‑roll tax rate in 2024-2025 was 5.45% for employers with total Australian wages in excess of AUD 1 200 000. Employers are entitled to an exemption from tax, or a pro-rated pay-roll tax threshold, on wages paid in New South Wales up to a maximum of AUD 1 200 000. The exempt amount is reduced based on the proportion of the employer’s New South Wales pay-roll to its total Australian pay-roll.

Universal cash transfers

Transfers related to marital status

There are no cash transfers made on a universal basis to married couples.

Transfers related to dependent children

Family Tax Benefit Part A (FTB(A)) is paid to a parent, guardian or an approved care organisation to help families meet the costs of raising children. For 2024-2025, the maximum rate of FTB(A) is payable where the combined adjusted taxable income of the family does not exceed AUD 65 189 per year, after which it tapers at a rate of AUD 0.20 per AUD 1 of income until an income limit that is determined by the number and age of dependent children. The base rate of FTB(A) is payable where the combined adjusted taxable income of the family is between the income limit and AUD 115 997, after which the payment shades out at the rate of AUD 0.30 per AUD 1 of income over the ceiling until the payment is nil. The base rate of payment is AUD 1 857.85 per annum (excluding the end of year supplement) for dependent children aged under 18 and for dependent full time students aged 16 to 19. A higher FTB(A) benefit is available for lower income earners, and the value of this benefit is dependent on the age and number of children. For 2024-2025 families may receive a maximum payment (excluding the end of year supplement) of AUD 5 788.90per annum for each child aged under 13 years and AUD 7 529.95per annum for each child aged 13 to 15 years and for each child aged 16 to 19 in full time secondary school. For 2024-2025 an end of year supplement of AUD 916.15per child is also available for families with a combined adjusted taxable income of less than AUD 80 000. However, people receiving any social security allowances or pensions automatically qualify for the maximum higher benefit. The attached calculations assume each dependant is between 5 and 12 years of age.

Family Tax Benefit Part B (FTB(B)) is targeted at couples with one main income and sole parent families. Eligibility for FTB(B) if you are a single parent or grandparent carer is contingent upon having a child under the age of 16 or a qualifying dependent full-time student up to of the end of the calendar year they turn 18. Eligibility for FTB(B) if you are a member of a couple with one main income is contingent upon having a dependent child aged under 13. There are two separate income tests applied to the parent(s). The parent earning the higher amount (or the sole parent, in the case of single parent families) must have an adjusted taxable income less than AUD 117 194 for the financial year for the family to be eligible. A secondary earner income threshold is also applied to the parent earning the lower amount. For 2024-2025, this threshold is AUD 6 789, above which the entitlement is reduced by AUD 0.20 for each AUD 1 of income. There is no secondary earner income test applied to sole parents. For 2024-2025, the maximum payment is AUD 3 883.60 (including a one-off supplement of AUD 448.95 paid at the end of the financial year) if the youngest dependent child is aged between 5 and 15 (or up to the end of the calendar year they turn 18 years if the dependent child is a full-time student), and AUD 5 372.80(including a one-off supplement of AUD 448.95 paid at the end of the financial year) if there is at least one child under 5 years. The attached calculations assume each dependant is between 5 and 12 years of age.

Recipients of the Family Tax Benefit may elect to receive the benefit in fortnightly instalments or as an end of year lump sum payment.

A Newborn Supplement and Newborn Upfront Payment may be paid to families for each baby born from 1 March 2014. To be eligible families will need to be eligible for FTB(A) and not be accessing Parental Leave Pay for that child. For multiple births, Parental Leave Pay may be payable for one child and Newborn Supplement for the other child or children. The total value of the Newborn Supplement and Newborn Upfront Payment in 2024-2025 is up to AUD 2 670.82 for the first child (and all multiple births) and up to AUD 1 335.85 for subsequent children.

Paid Parental Leave is provided through Parental Leave Pay (PLP) which can be shared with an eligible partner. Previously, Dad and Partner Pay (DAPP) could be claimed, however, it has been combined into PLP as of 1 July 2023. Eligible parents with a child born or adopted from 1 July 2024 will receive up to 22 weeks’ pay at the national minimum wage (AUD 915.80 per week before tax) in 2024-2025. For partnered parents, generally the most PLP a person can take is 20 weeks as 2 weeks are reserved for each partner and a maximum of 2 weeks can be taken concurrently. Single parents are eligible for the full 22 weeks. The date of the child’s birth or adoption will determine how many PLP weeks are available as the scheme undergoes an expansion to 26 weeks by 1 July 2026 and the weeks reserved for each partner increasing. The total number of PLP days do not have to be used in a continuous block but must be taken within 2 years of the child’s birth or adoption. Claimants must be caring for a newborn or recently adopted child and must have worked for at least 10 of the 13 months prior to the birth or adoption, and for at least 330 hours in that 10 month period with no more than a twelve week gap between two working days. To be eligible an individual’s adjusted taxable income must be equal to or less than an income test threshold in the financial year prior to the date of claim or date of birth or adoption, whichever is earlier. The individual income test threshold that applies for children born or adopted from 1 July 2024 is AUD 175,788 (for the assessed 2023-24 financial year). If an individual does not meet the individual income test then a family income test can be used which assesses family adjusted taxable income. The family income test threshold that applies for children born or adopted from 1 July 2024 is AUD 364,350 (for the assessed 2023-24 financial year). PLP and Newborn Supplement cannot be paid for the same child. A person cannot claim FTB(B) while they are receiving PLP.

Child Care Subsidy (CCS) is a means-tested payment which assists families with the cost of approved child care services. CCS is payable to eligible families with incomes up to AUD 533 280. A percentage of the cost of childcare is subsidised. For families with one child aged 5 or under, the applicable percentage is 90 per cent for families with income less than AUD 83 280 and reduces by 1 per cent for each AUD 5 000 of income above AUD 83 280, until it reaches 0 per cent for families earning AUD 533 280. Families with more than one child aged 5 or under received a higher subsidy for the second and subsequent children. They receive the maximum subsidy percentage of 95 per cent up to a maximum income threshold of AUD 141 321. In 2024-2025, there was no annual cap on the CCS. The attached calculations assume no childcare usage.

Other transfers

Income support payments in Australia are assessed on fortnightly income. The descriptions below present annualised estimates of fortnightly rates and thresholds by summing up applicable rates across the 2024‑2025 year. The modelled results presented in Taxing Wages 2024-2025 reflect people who have constant income over an entire year. In practice, it is common for fortnightly payment values to fluctuate as recipients’ circumstances change.

JobSeeker Payment

JobSeeker Payment is the primary taxable payment payable to people aged from 22 years to Age Pension age (67 years in 2024-2025) who are unemployed or are regarded as unemployed. JobSeeker Payment is also payable to a member of a couple if their youngest child is aged 6 years or more and to single parents if their youngest child is aged 14 years or more. It is typically conditional on recipients fulfilling a personal Job Plan, which typically involves taking part in activities such as job seeking or training. In 2024‑2025 the annual JobSeeker amount for singles without dependants (that are not eligible for the higher payment rate) was AUD 20 157.90 and for partnered individuals was AUD 18 455.40. Recipients are also eligible for an Energy Supplement, and potentially other supplementary payments. These payments typically taper out at a rate of AUD 0.50 per AUD 1 for incomes between AUD 3 900 and AUD 6 656, and reduce at a rate of AUD 0.60 per AUD for incomes over AUD 6 656. Under the thresholds and taper rates that applied in 2024-2025, the JobSeeker payment may be available to some full-time workers under the OECD definition of 30 or more hours of work per week. The JobSeeker Payment for partnered individuals reduces by AUD 0.60 for each AUD 1 of their partner’s income above AUD 35 698. For single principal carers with dependent child or children, it reduced at a rate of AUD 0.40 per AUD 1 for incomes over AUD 3 900.

Parenting Payment

Parenting Payment is a taxable payment payable to low income families with responsibility for the care of a young child. Partnered persons are eligible if they have a qualifying child under six years of age, and sole parents are eligible if they have a qualifying child under fourteen years of age.

In 2024-2025 the maximum annual amount of Parenting Payment (Partnered) (PP(P)) was AUD 18 789. Only one parent in a couple can be entitled to PP(P). The maximum annual amount of Parenting Payment (Single) (PP(S)) in 2024-2025 was AUD 26 104.20. Recipients are also eligible for an Energy Supplement, and potentially other supplementary payments. These payments are subject to income and assets tests. The PP(P) tapers out at a rate of AUD 0.50 per AUD 1 of income over AUD 3 900 up to AUD 6 656, and reduces at a rate of AUD 0.60 per AUD 1 for income over AUD 6 656. Under the PP(P) income test, a spouse typically receives a reduced Parenting Payment, tapering at a rate of AUD 0.60, when the higher earning partner’s income exceeds AUD 35 472. If the spouse has little or no income (less than AUD 3 900 per annum), he or she would not receive any Parenting Payment when the higher earning partner’s income exceeds AUD 66 573. PP(S) reduces by AUD 0.40 for each AUD 1 of income above AUD 5 735.60 plus AUD 639.60 for each child other than the first.

Pharmaceutical Allowance

Pharmaceutical Allowance (PA) is a non-taxable supplementary payment payable to eligible persons to help with medicine costs; for example, persons who receive the PP(S). PA is added to the maximum basic rate of PP(S) before a person’s PP(S) entitlement is calculated. Anyone with a PP(S) entitlement, after PA has been added, receives the full amount of PA. For 2024-2025, the payment is AUD 176.80 for singles and AUD 88.40 for coupled individuals.

Telephone Allowance

A non-taxable Telephone Allowance is available on a quarterly basis to eligible individuals, including individuals who receive PP(S). The basic rate of the Telephone Allowance is AUD 146.71 for 2024-2025.

Energy Supplement

The Energy Supplement (ES) is an extra payment to help with energy costs, paid alongside certain income support payments. The ES is not indexed. The amount of the supplement varies depending on the main income support payment. FTB(A) and FTB(B) recipients are only eligible for the ES if they have been continuously eligible for their payment since 19 September 2016.

For eligible FTB(A) recipients, the maximum amount of ES is AUD 91.25 per year for each child under 13 years and AUD 116.80 for each child aged 13 to 15 years and for each child aged 16 to 19 in full time secondary school.

For eligible FTB(B) recipients, the amount of ES is AUD 73.00 per year where the youngest child is under 5 years, and AUD 51.10 per year where the youngest child is aged 5 to 18 years.

Recipients of PP(P) receive AUD 205.40 annually, and recipients of PP(S) receive AUD 312.

For JobSeeker Payment recipients, the ES is typically AUD 228.80 annually for singles without dependents, and AUD 205.40 for partnered individuals.

The calculations assume families and individuals are eligible for the energy supplement as a significant proportion of FTB(A) and FTB(B) recipients were eligible for the supplement in 2024-2025.

Recent changes in the tax/benefit system

Changes to Paid Parental Leave

Dad and Partner Pay and Parental Leave Pay combined into one payment for children born or adopted from 1 July 2023.

Increases to JobSeeker and Student Payments

On 20 September 2023, the base rates of working age and student payments, including JobSeeker Payment, Youth Allowance, Parenting Payment (Partnered), Austudy, ABSTUDY, Disability Support Pension (Youth), and Special Benefit, increased by $40 per fortnight.

Eligibility for the existing higher rate of JobSeeker Payment was extended to single recipients aged 55 to 59, who are on payment for nine or more continuous months. Previously the qualifying age for this higher rate was 60.

From 20 September 2024, the higher rate of JobSeeker Payment was extended to persons with a partial capacity to work. Previously, persons with partial capacity to work less than 15 hours per week received the same base rate of JobSeeker Payment as other recipients who were able to work full-time, but did not face additional living costs due to impairment.

Increases to Parenting Payment (Single)

From 20 September 2023, eligibility for Parenting Payment (Single) was extended to single principal carers with a youngest dependent child under 14 years (up from 8 years).

Changes to Superannuation Guarantee

Before 1 July 2022, Superannuation Guarantee did not have to be paid for a worker earning less than AUD 450 a month. From 2022-23 onwards, this threshold was removed. Superannuation Guarantee must now be paid to all workers 18 and older regardless of their earnings.

Memorandum items

Identification of an average worker

The source of the information used in replying to the questionnaire was the Australian Bureau of Statistics (ABS) publication Average Weekly Earnings — Australia. The survey is now conducted on a biannual basis (it was previously conducted on a quarterly basis up to the June 2012 quarter) and is based on a representative sample of employers in each industry. As a result of this change in frequency, average weekly earnings for the 2024-2025 income tax year have been calculated as the average of the two biannual figures (November 2024 and May 2025 (released in August 2025)).

In August 2009, the ABS redesigned the survey and replaced the industry classification based on the 1993 edition of the Australian and New Zealand Standard Industrial Classification (ANZSIC), which had been in use since 1994, with the 2006 edition of ANZSIC. The 2006 edition of ANZSIC was developed to provide a more contemporary industrial classification system, taking into account issues such as changes in the structure and composition of the economy, changing user demands and compatibility with major international classification standards. Accordingly, the average wage figure for 2010 and later years is inconsistent with that provided for previous years.

All wage and salary earners who received pay for the reference period are represented in the Survey of Average Weekly Earnings (AWE), except:

• members of the Australian permanent defence forces;

• employees of enterprises primarily engaged in agriculture, forestry and fishing;

• employees of private households;

• employees of overseas embassies, consulates, etc.;

• employees based outside Australia; and

• employees on workers’ compensation who are not paid through the payroll.

Also excluded are the following persons who are not regarded as employees for the purposes of this survey:

• casual employees who did not receive pay during the reference period;

• employees on leave without pay who did not receive pay during the reference period;

• employees on strike, or stood down, who did not receive pay during the reference period;

• directors who are not paid a salary;

• proprietors/partners of unincorporated businesses;

• self-employed persons such as subcontractors, owner/drivers, consultants;

• persons paid solely by commission without a retainer; and

• employees paid under the Paid Parental Leave Scheme.

The sample for the AWE survey, like most ABS business surveys, is selected from the ABS Business Register which is primarily based on registrations with the Australian Taxation Office's (ATO) Pay As You Go Withholding (PAYGW) scheme (and prior to 1 June 2000 the Group Employer (GE) scheme). The population is updated quarterly to take account of:

• new businesses;

• businesses which have ceased employing;

• changes in employment levels;

• changes in industry; and

• other general business changes.

Earnings comprise weekly ordinary time earnings and weekly overtime earnings.

Weekly ordinary time earnings refers to one week’s earnings of employees for the reference period attributable to award, standard or agreed hours of work. It is calculated before taxation and any other deductions (e.g. board and lodging) have been made. Included in ordinary time earnings are award, workplace and enterprise bargaining payments, and other agreed base rates of pay, over award and over agreed payments, penalty payments, shift and other allowances; commissions and retainers; bonuses and similar payments related to the reference period; payments under incentive or piecework; payments under profit sharing schemes normally paid each pay period; payment for leave taken during the reference period; all workers’ compensation payments made through the payroll; and salary payments made to directors. Excluded are overtime payments, retrospective pay, pay in advance, leave loadings, severance, termination and redundancy payments, and other payments not related to the reference period.

Weekly overtime earnings refers to payment for hours in excess of award, standard or agreed hours of work.

Employers’ contribution to private health and pension scheme

In Australia very few employers make any contributions towards health schemes for their employees, especially where the employee is at a wage level comparable to that of an average production worker.

Employer contributions to pension schemes are primarily through the superannuation system. This is described in section 2.2.

2024-25 Tax Equations

The equations for the Australian system in 2024-25 are mostly repeated for each individual of a married couple. However, the spouse credit is relevant only to the calculation for the principal earner and the calculation of the Medicare levy uses shading-in rules which depend on the levels of earnings of the spouses. The basis of calculation is shown by the Range indicator in the table below.

The functions which are used in the equations (Taper, MIN, Tax etc) are described in the technical note about tax equations. Variable names are defined in the table of parameters above, within the equations table, or are the standard variables “married” and “children”. A reference to a variable with the affix “_total” indicates the sum of the relevant variable values for the principal and spouse. And the affixes “_princ” and “_spouse” indicate the value for the principal and spouse, respectively. Where the calculation for one earner considers variables for the other earner, the affix "_oth" is used. Equations for a single person are as shown for the principal, with “_spouse” values taken as 0.

Key to range of equation B calculated separately for both principal earner and spouse P calculated for principal only (value taken as 0 for spouse calculation) J calculated once only on a joint basis. Key refers to an optimisation of benefits i.e. Parenting Payment for principal and JobSeeker Payment for spouse versus Parenting Payment for spouse and JobSeeker Payment for principal.
