Receiving your letter
We may send you a letter about the Medicare levy surcharge (MLS) if we receive information that shows, for all or part of the relevant year, you or any of your dependants (including your spouse):
- were not a member of a registered health fund
- did not have an appropriate level of private patient hospital insurance cover
- had family income that was above the MLS threshold.
The letter will include an MLS schedule that compares relevant information from your tax return with information we have received.
We'll send the letter to the most recent postal address we have for you.
What to do
There are 2 types of MLS letters and each requires a different action:
- Have you reported your Medicare levy surcharge correctly?
- Your Medicare levy surcharge may be incorrect.
For both letters, you need to review the MLS schedule and compare the information with your records. You can then determine if you agree or disagree.
Letter 1: Have you reported your Medicare levy surcharge correctly?
