What is the Medicare Levy Surcharge?

If you are an Australian taxpayer eligible for Medicare who doesn't have private hospital insurance, and you earn over a certain amount, you may have to pay the Medicare Levy Surcharge (MLS). The MLS is a Federal Government initiative and is an extra 1% to 1.5% in tax on top of the normal 2% Medicare Levy we all have to pay if you don't hold private Hospital cover.

How does it affect me and my tax?

If you earn above the Australian Government income threshold and don’t have an appropriate level of private hospital cover for the full financial year, you may have to pay the Medicare Levy Surcharge. This is an additional tax on top of the standard Medicare Levy. Thresholds and rates may change, so check the latest information on the ATO Medicare Levy Surcharge thresholds and rates page.
