The Australian Taxation Office has been yet again forced to shut down parts of its website to carry out maintenance.
The ATO said its portals, myTax and other online services would be taken offline on Wednesday afternoon to resolve "some intermittent system issues".
"We'll provide an update when the services are once again available. We apologise for the inconvenience," it tweeted.
The website has been dogged by system issues in recent months, with major outages in December, February and as recently as last week.
