Track your presence in Australia for the 183-day tax residency test. The Australian income year runs from 1 July to 30 June. You may be considered an Australian resident under this test if you are present in Australia for 183 days or more during the income year, continuously or intermittently, unless your usual place of abode is outside Australia and you do not intend to take up residence in Australia. Any part of a day present in Australia generally counts as a whole day. In an income year containing 366 days, the statutory “more than half of the income year” threshold may require 184 days. This tracker covers the day-count element only; other Australian tax residency tests may also apply.
