Why did the rate change when nothing changed?
A new letter arrives from Services Australia. The contribution percentage has moved — up this time — and yet nothing at home has changed: same income, same savings, same house, same pension, as far as anyone can tell. For part pensioners, this mystery has a real mechanism behind it, and for one group of families — those with a pension or income from overseas — the answer can be as far away as the currency markets.
The chain that moves the rate
For part pensioners (and non-pensioners whose income is under the Seniors Health Card limit), the Support at Home contribution rate is not a fixed number — it sits in a band, and Services Australia sets the exact point from the means picture it holds. That means the rate rides on everything the means assessment rides on: deemed income from financial assets (the deeming rates and thresholds themselves change on set dates), pension indexation each March and September, and any reassessment of income. Change any link and the letter changes — even though nobody at home did anything.
The link is direct, because the Rules build the contribution rate out of the pension tests themselves: half of your income above the pension income free area, or 7.8% of your assets above the pension assets limit, whichever is larger, sets where you sit in the band. (The part pensioner guide walks through the sum.) So anything that moves your assessed income or assets moves your rate in a straight line.
A recent example. On 20 September 2026 the deeming rates rose, to 1.75% and 3.75%. Deeming is the income Centrelink assumes your savings earn, so a higher deeming rate means a higher assessed income for anyone with savings above the threshold — without a single dollar changing in the bank. If a new rate letter arrived after that date showing a slightly higher percentage, this is the most likely reason. The pension thresholds were indexed on the same day, which pulls the other way, so the net effect differs from person to person.
The overseas-income wrinkle
Here is the part almost nobody explains: overseas pensions and income are assessed in Australian dollars. When the exchange rate moves, the Australian-dollar value of that overseas income moves with it — which can shift the assessed income, which can shift the part pension, which can shift the contribution percentage. A family can experience their aged care costs changing because a currency moved, with the rate letter offering no explanation beyond new numbers. Two boundaries are worth understanding. Moving between a part pension and a full pension does not cause a jump — the full-pension rates are simply the bottom of the same line. Losing the pension altogether does not cause a jump either: the Rules keep you on that same line as long as your income would pass the Commonwealth Seniors Health Card income test, whether or not you actually hold the card (section 314-40). The top rates apply only above that income limit, or where means have not been disclosed. So if a rate leaps to the maximum after a pension change, that is worth querying. Migrant families are most exposed, and — as the reader who prompted this guide put it — often least resourced to question it, because the same families face the language barrier too.
The audit trail that explains every change
- Keep every rate letter. Each change should trace to a reassessment. The letters, in date order, are the audit trail — if a change appears without a letter, that is itself a question for Services Australia.
- Ask for the basis, in writing. Via myGov (which creates a record) or the aged care line (1800 227 475): “Please provide the calculation basis for the contribution rate in your letter of [date], including the income and asset figures used.” If the figures look wrong, the magic words are: “I would like a formal review of this decision.”
- Free interpreters exist for every one of these calls. The Translating and Interpreting Service (131 450) connects an interpreter to Services Australia, My Aged Care or the provider at no cost — the system is required to speak your language, not the other way around.
- Report changes within 28 days. You must tell Services Australia within 28 days of any change in your finances that may affect your contribution (Support at Home Program Manual, section 9.5). Reporting late never helps you. The date a new rate starts from is set by transitional rules that are due to lapse at the end of October 2026, so we are not quoting a section for it here: check the start date printed on your letter, and if the date looks wrong, ask Services Australia in writing which rule it applied.
- Answer information requests quickly. If Services Australia asks for your income and assets details and does not get them within 43 days, it can treat your means as “not disclosed” (section 314A-5) — and that status carries the maximum rates. A rate that leaps to the top of the scale for no visible reason is worth checking against an unanswered letter.
- Know the review window. A request to have a decision reconsidered must be in writing, with your reasons, within 28 days of being notified — or 90 days where the decision is about your assessable income (Aged Care Act, section 559). You can ask for more time.
The ceiling for grandfathered families
If you (or your parent) were in home care — or approved or waiting for it — on or before 12 September 2024, two protections blunt the whole mechanism: the assessment is income-only (assets excluded), and for those who paid an income-tested fee, a fortnightly cap limits what any fortnight can cost — roughly the old daily fee times fourteen. Whatever the currency does, the cap is meant to be the ceiling. If fortnights on the statement exceed it, ask Services Australia in writing to confirm the grandfathered contribution amount payable, including the cap — they are required to notify it.
The cap is in the law, not just the manual. The Aged Care Act (section 273(2)) lets the Rules set a different contribution in particular circumstances, and the Aged Care Rules (section 273-10, item 4) set it to zero where three things are true: you were approved for home care on 12 September 2024; you had an income-tested care fee immediately before 1 November 2025; and the contributions charged to you over “the preceding fortnight” exceed that old daily fee multiplied by 14. Two limits are worth knowing. The cap is tied to having had an old fee, so it gives you nothing to point to if you never had one. And the Rules do not spell out how “the preceding fortnight” is counted, so if your provider and Services Australia count it differently, ask for the method in writing.
