residex.ioEvery trip accounted forAustralia’s 183-Day Test
A July-to-June year, and a test that only kicks in if you do not already “reside” there
The year starts in July
Australia’s income year runs from 1 July to 30 June. A count kept on the calendar year is simply the wrong number: four months in Australia from March and three more from July look like seven months in one calendar year, and are four in one income year and three in the next.
residex.io counts Australian days on the July year for that reason.
Four tests, and the day count is not the first
The primary test is whether you reside in Australia in the ordinary sense — where you live, your family, your ties, your intentions. If you do, you are resident regardless of days. The three statutory tests come after it: the domicile test, the 183-day test, and the Commonwealth superannuation test.
The 183-day test itself has a get-out. Meeting it makes you resident unless your usual place of abode is outside Australia and you do not intend to take up residence there. Someone on a long working holiday can meet the day count and still be non-resident; someone with a home and family in Sydney can be resident on 120 days.
Leaving is its own question
The tests apply differently to people departing. An Australian who takes a two-year posting abroad may remain resident under the domicile test unless they have a permanent place of abode overseas, and the day count says nothing about that. A proposed replacement — a bright-line 45-day test with a factor test behind it — has been discussed for several years and is not law at the time of writing.
What residex.io does about it
Residex counts your days in Australia over the 1 July income year, warns as you approach 183, and can notify you on the date a planned trip would take you past it. It does not run the resides test or the domicile test: they turn on where you live and intend to live, not on how many days you were there.
Who needs to watch this
- Working-holiday makers and temporary visa holders
- Australians on overseas postings who visit home
- Retirees splitting the year with Southeast Asia or Europe
- Anyone counting on a January-to-December year
Counting days is where this stops
Residex tells you exactly where you stand against this threshold and warns you before you cross it. Crossing it is not a conclusion, though: it does not tell you what you owe, whether a treaty offers relief, which forms to file, or how this interacts with residency you already hold elsewhere.
That is where Amanda picks up — turning a day count into a read on your real cross-border obligations.

How residex.io works
residex.io tracks where you have physically been, and tells you where that puts you against each country's own residency threshold.
What it does: • Counts your days per country, and per area for the Schengen 90/180 rule • Applies each country's actual rule — 183 days for most, 180 for Thailand, the UK's 6 April tax year, Portugal's rolling twelve months, and the US weighted three-year test • Counts days the way each rule counts them, including the arrival and departure days that most tests count and a nights-based tally misses • Warns as you approach a threshold, and can notify you on the date a trip you have already planned would take you across it • Exports to CSV, or hands off to Amanda for the compliance picture
Built for digital nomads, frequent travellers, expats, and anyone whose year is split across borders.
On your device, and nowhere else. There is no account, no login, and no copy of your travel history on our servers — residex works offline because the data never needed to be anywhere else.
It leaves your device only when you decide to send it: • A backup file you save yourself • A transfer to another device, encrypted with a code only you hold — the server relaying it cannot read what it is carrying • A hand-off to Amanda, which you start
We do receive a small amount of anonymous usage information — how many trips are in a log, how old an install is, the language the app is used in, and a random identifier that is not linked to you. Never a trip, a date, a destination, or your name. It is listed in full in our Privacy Policy.
The trade-off worth knowing: because your device holds the only copy, clearing your browser data or deleting the app erases it, and we cannot restore it. Save a backup before you switch devices.
No — residex is a day counter, not a compliance engine. It flags when you cross a threshold like the 183-day rule, but turning that into specific filings, tax exposure, or reporting obligations depends on your jurisdictions and personal ties.
For that, our partner Amanda maps your full cross-border legal exposure across countries, surfaces the filings and deadlines you trigger, and turns the data residex collects into a concrete compliance picture you can hand to your accountant.
You can export your residex trips and import them straight into Amanda — the CSV formats are aligned.
