Private Health Insurance After Separation in Australia

A joint couple or family health insurance policy cannot be maintained once you and your ex-spouse are living at separate addresses. Your fund won't cover two separate households under one couple policy — and letting the policy lapse triggers consequences at tax time.

Splitting the Policy

Contact your health insurer as soon as you separate. Most funds will split a family or couples policy into two individual policies without triggering new waiting periods, provided both parties maintain continuous cover.

The standard process:

1. Call your fund and request a policy separation
2. One person stays on the original policy (downgraded to single or single-parent cover)
3. The other person takes out a new individual policy — either with the same fund or a different one

If you switch to a new fund, ask for a clearance or transfer certificate so the new fund can credit waiting periods you've already served on equivalent cover. The statutory maximum waiting periods are 12 months for pre-existing conditions and 2 months in other circumstances, but new or upgraded benefits may have waiting periods; confirm the timing with the new fund before cancelling.

Children's Cover

Children can be covered under both parents' policies simultaneously — this is common in shared care arrangements. Or you can agree that one parent covers the children. The child's cover doesn't need to match the custody arrangement, but whoever claims the Private Health Insurance Rebate at tax time needs to hold the policy that covers the child.

If you're the primary carer and your ex-spouse was the policyholder, get the children onto your policy before the original one is changed. A gap in children's cover can affect continuity and may mean waiting periods apply again. Arrange the new cover before changing the original policy and check with the fund.

The Medicare Levy Surcharge

The MLS is the hidden cost of letting health insurance lapse after divorce. While married, the MLS family income threshold is approximately $186,000 combined. After separation, you're assessed individually against the single threshold — $101,000 for 2025/26 or $105,000 for 2026/27.

If your individual taxable income exceeds the threshold and you don't hold hospital cover, the ATO charges the MLS at 1% to 1.5% of your taxable income. On a $120,000 salary, that's $1,200–$1,800 at tax time — which could have been avoided by maintaining a basic hospital policy.

The surcharge applies from the first day you're without cover over the threshold. Don't wait until after the divorce is finalised — if you separate and lose cover partway through the financial year, the ATO pro-rates the surcharge for the uncovered days.

Lifetime Health Cover Loading

If you're over 30 and have never held hospital cover (or let it lapse for more than a continuous period specified by your fund), you'll pay a Lifetime Health Cover (LHC) loading — an extra 2% on top of your premium for every year over 30 that you were without cover, up to a maximum 70% loading.

If your ex-spouse held the policy and you were a dependant who never held cover in your own name, ask the fund how your LHC status and transfer certificate will be treated.

The Tasmania After-Divorce Checklist includes a health insurance checklist that covers policy separation timing, children's cover arrangements, and MLS threshold calculations.
