When one partner of an Age Pension couple enters permanent residential aged care, section 4(7) of the Social Security Act creates 'illness-separated couple' status: both partners are paid the higher single rate while assets and income are still assessed as a couple. This lifts combined pension from $1,810.40 to $2,401.80 per fortnight — about $15,400 a year — but must be claimed within 14 days of the move.
When one partner of an Age Pension couple enters permanent residential aged care, the social security treatment of the household changes in a way that produces a substantial cash-flow uplift — roughly $15,400 per year for the couple. The provision sits in section 4(7) of the Social Security Act 1991 and creates a status known as the illness-separated couple. The mechanic is genuinely unusual: the couple is still treated as a couple for the assets and income tests, but each partner is paid at the higher single rate of pension. Two single-rate payments flow to two separate bank accounts, with two separate concession cards, while the combined asset and income limits continue to apply.
The legal definition is straightforward. An illness-separated couple is a couple who, but for the fact that they cannot live together due to the illness or infirmity of one or both of them, would be living together. The triggering circumstances are permanent residential aged care, long-term hospital admission, or each partner being in a different aged care facility. Short-term illness or temporary separation does not qualify. The illness or infirmity must be such that the couple cannot live together — typically established by the aged care admission paperwork itself.
The dollar uplift is the headline. Under the maximum rates effective 20 March 2026 to 19 September 2026, a couple living together receives a combined $1,810.40 per fortnight ($905.20 each). Two illness-separated partners are each paid at the single maximum of $1,200.90 per fortnight — $2,401.80 combined (DSS Guide 5.1.8.10, https://guides.dss.gov.au/social-security-guide/5/1/8/10). The illness-separated status takes the household from $1,810.40 combined to $2,401.80 combined — an increase of $591.40 per fortnight, or about $15,400 per year. For a household facing the daily fee, the accommodation contribution, and the means-tested care fee that typically accompany permanent residential aged care, that additional income is a meaningful offset against the cost of care.
The status does not apply automatically. Services Australia must be notified of the change in living arrangements within 14 days under the standard notification rule. Documentation typically required includes the aged care facility's admission paperwork, confirmation that the care is permanent rather than respite, and sometimes medical evidence supporting the underlying illness or infirmity. The status takes effect from the date of notification, with reasonable backdating to the date of permanent care commencement where the delay can be justified. Failing to notify within the 14-day window can produce overpayments or underpayments depending on the direction of the rate change.
The principal home exemption operates alongside, not because of, the illness-separated status. For the partner in care, the principal home remains exempt from the assets test for 24 months from the date of permanent care commencement (Services Australia, https://www.servicesaustralia.gov.au/assets-test-for-age-pension?context=22526). After that period, the home becomes assessable for the partner in care if the other partner is no longer living there. The home remains exempt for the partner who continues to reside in it as their principal residence regardless of how long the other partner has been in care. This is a separate provision from section 4(7) and operates on its own clock.
The aged care means assessment runs in parallel and uses different rules. The pooled couple assets are split 50/50 for the means assessment of the partner in care. The principal home is exempt under the protected person rule if the other partner remains in residence. The pension uplift from illness-separated status does not directly change the means assessment — though the income increase can reshape the income-tested portion of the means-tested care fee. The two regimes interact in non-obvious ways and benefit from coordinated review.
The most common misunderstandings are worth correcting. The illness-separated status does not apply automatically — it must be claimed and documented. The assets and income tests do not shift to single bases — they remain combined. The home does not become immediately assessable on entry to aged care — the 24-month exemption applies. Tax law has its own spouse definition — the couple remain spouses for ATO purposes regardless of social security status.
Section 4(7) is a quiet provision with substantial financial consequences for couples navigating the transition into aged care. Claiming the illness-separated status promptly is one of the highest-value administrative tasks at this point in a retirement trajectory — and one of the most commonly overlooked.

Key takeaways
- Under section 4(7) of the Social Security Act 1991, a couple who cannot live together due to illness or infirmity of one or both partners — typically triggered by permanent residential aged care admission — can be assessed as an illness-separated couple, with each partner paid at the higher single pension rate while assets and income remain assessed on a combined couple basis.
- The dollar uplift is substantial: a couple living together receives a combined $1,810.40 per fortnight ($905.20 each), while an illness-separated couple receives $2,401.80 combined ($1,200.90 each) — an increase of $591.40 per fortnight, or about $15,400 per year, as at rates effective 20 March 2026.
- The status doesn't apply automatically — Services Australia must be notified within 14 days, with documentation typically including the aged care facility's admission paperwork and confirmation the care is permanent rather than respite; reasonable backdating to the date of permanent care commencement is possible where the delay is justified.
- The principal home's assets test exemption operates on its own separate 24-month clock from section 4(7) — the home remains exempt for the partner in care for 24 months from the date of permanent care commencement, and stays exempt indefinitely for a partner who continues to live in it.
- The aged care means assessment runs on entirely separate rules, splitting pooled couple assets 50/50 for the partner in care and applying the protected person home exemption if the other partner remains in residence — the pension uplift doesn't directly change this means assessment, though the extra income can affect the income-tested portion of the means-tested care fee.
Frequently asked questions
What is illness-separated couple status?
It's a status under section 4(7) of the Social Security Act 1991 that applies when a couple can't live together due to the illness or infirmity of one or both partners — most commonly when one partner enters permanent residential aged care. Each partner is then paid at the higher single Age Pension rate, while their combined assets and income continue to be assessed as a couple.
How much extra pension does illness-separated status provide?
As at rates effective 20 March 2026, a couple living together receives $1,810.40 per fortnight combined, while an illness-separated couple receives $2,401.80 combined — each partner paid the single rate of $1,200.90. That's an increase of $591.40 per fortnight, or about $15,400 per year, which can meaningfully offset the cost of aged care fees.
Do I need to apply for illness-separated couple status, or does it happen automatically?
You need to notify Services Australia within 14 days of the change in living arrangements. Documentation typically required includes the aged care facility's admission paperwork and confirmation the care is permanent rather than respite. The status takes effect from the date of notification, with reasonable backdating to the date permanent care began if the delay can be justified.
Does illness-separated status affect whether the family home is exempt from the assets test?
Not directly — the home exemption runs on its own separate clock. The principal home remains exempt from the Age Pension assets test for 24 months from the date the partner enters permanent care, and stays exempt indefinitely for a partner who continues to live in it. This is a distinct provision from section 4(7), and it applies regardless of illness-separated status.
