Gazette notice: Commissioner of Taxation – Notice of a private health insurance statement data-matching program 8 December 2022

The Australian Taxation Office (ATO) will acquire private health insurance (PHI) statement data from private health insurance statement providers for 2014–15 through to 2027–28.

The data items include:

  • software provider's identification details – name of the organisation sending the data, addresses, email addresses, phone numbers, Australian Business number etc.
  • PHI provider's identification details – business and trading name, fund code, addresses, email addresses, phone numbers, Australian Business number etc.
  • insured individuals' identification details – policy membership number, unique personal identifier, names on the policy, dates of birth, addresses, email addresses, phone numbers etc.
  • PHI statement details – policy membership number, unique personal identifier, policy role, premium paid in the financial year, Australian Government rebate received, premium eligible for Australian Government rebate, benefit code, Medicare levy surcharge (MLS) record start and end date etc.

We estimate that records relating to approximately 14.6 million individuals will be obtained each financial year.

The ATO acquire and match the data for the administration and enforcement of tax and superannuation laws by:

  • making the data available in our pre-filling service to assist taxpayers to meet their obligations
  • undertaking compliance checks to determine:  
    • liability for MLS
    • eligibility for the private health insurance rebate (PHIR).

These obligations may include registration, lodgment, reporting and payment responsibilities.

The objectives of this program are to:

  • promote voluntary compliance and increase community confidence in the tax and superannuation systems
  • assist taxpayers with their reporting, by pre-filling tax returns with PHI statement data
  • speed up processing of income tax returns by making the PHI statement data available in our online services
  • identify taxpayers who are entitled to claim the private health insurance rebate (PHIR)
  • identify the taxpayers who have to pay the Medicare levy surcharge (MLS)
  • gain insights to help develop and implement strategies to help improve voluntary compliance; strategies may include educational or compliance activities
  • identify and educate individuals who can't meet their registration or lodgment obligations and assist them to comply
  • help ensure individuals are meeting their tax and superannuation obligations.
