Eligible medical expenses – what’s included

From 2015-16 (until 2018-19) transitional arrangements only allow claims for disability aids, attendant care or aged care expenses.

What qualifies as medical expenses is legally defined, but quite wide-ranging. In general it is restricted to payments to legally registered practitioners, for an illness or operation or for medical conditions.

  • This includes payments to or for doctors, nurses, chemists, dentists and public and private hospitals. It excludes cosmetic procedures which Medicare doesn’t support, and claims cannot include expense amounts reimbursed under Medicare or health insurance cover.
  • See here for Allowable medical expenses

Phase-out of medical expenses claims

From 2015-16 (until 2018-19) transitional arrangements only allow claims for disability aids, attendant care or aged care expenses.

Medical Expenses – Who For?

The medical expenses you can claim are limited to yourself and your spouse, and certain dependent relatives subject to qualifying conditions:

  • children under 21 years or student children under 25 years
  • child housekeeper
  • invalid relatives

Offset is not refundable

Medical Expense Offsets are not refundable if the amount of the offset is greater than your tax payable.

Net Medical Expenses Tax Offset rates and Thresholds

Higher Income Earners – From 1 July 2012 income-tested

From 1 July 2012 the rebate is subject to an income test which is based on the Medicare levy surcharge income minimum thresholds. Higher income earners have a reduced offset rate of 10% and a higher minimum expenses threshold (over $5,000).

The income test is based on Adjusted Taxable Incomes with respect to the Medicare levy surcharge higher income thresholds.

  • “Adjusted Taxable Income” is your declared taxable income with certain fringe benefits, exempt income and losses added back – see ATI

 ‘Higher Income’ Thresholds 

Change to Adjusted Taxable Income Formula

The meaning of ‘adjusted fringe benefits total’ is modified so that the gross value rather than adjusted net value (previously 51%) of reportable fringe benefits is used, except for PBIs, hospitals and charities.

The government has adjusted the formula for the inclusion of the value of fringe benefits in Adjusted Taxable Income.

‘adjusted fringe benefits total’ is a component of Adjusted Taxable Income

This affects eligibility for:

  • family tax benefits, stillborn baby payment,child care benefit, Youth Allowance, Abstudy and Isolated Children’s Allowance
  • parental leave pay and dad and partner pay
  • net medical expenses offset
  • dependant (invalid and carer) (DICTO) tax offset
  • Notional dependent’s offset for the Zone & overseas personnel tax offsets

For details of the amending legislation see Budget Savings (Omnibus) Act 2016 (Schedule 15). The measures received royal assent on 16 September 2016 and according to its terms therefore take effect from 1 January 2017 for family assistance payments and for income tax tests from 1 July 2017.

Medical Expense Offset claim calculation

Subject to entitlement, the procedure for working out a Medical Expense Offset claim is as follows:

  1. Determine eligible expenditures paid within the tax year
  2. Ensure all reimbursements are deducted
  3. Deduct your minimum threshold amount for that tax year – determined by income
  4. Multiply the result by 20% (or 10% in 2012-13 and later years depending on income)
  5. The result is your Medical Expenses Tax Offset which is deducted from your tax payable, with any unused amount not refundable.
