Tax commissioner Chris Jordan addressed staff at the Smollett Street office on Thursday after flying in from his Sydney base.

His visit follows job losses with the outsourcing of image capturing work which was done at the Albury and Penrith ATO sites.

"We're shipping work to Albury to keep that part-time work intact, to replace the imaging capture work with other sorts of work because it is a good workforce," Mr Jordan said.

The Albury office employs 1260 overall, with 530 permanents and 730 casuals.

Mr Jordan said there was little prospect of more employees being hired, but he does not anticipate any cuts.

"We're pretty much the size we are going to be that I'm certainly aware of, I can't speak for the government forever, but I'm really pleased with the Albury workforce," Mr Jordan said.

"They're a very engaged workforce, in terms of comparisons to the ATO average they are happier in their jobs, they're positive in their positions and that's why we are happy to make sure there is enough work coming to Albury to maintain not only the full-time jobs but a good pool of really long-term part-time people."

Mr Jordan said there was a "compelling" case to maintain the Albury branch, which is one of five ATO offices outside a capital city.

"There is a motivated workforce, it has got a university, you've got a good talent pool to draw on, so we're quite happy to maintain a sizable presence here in Albury," Mr Jordan said.

Asked about the scrapping of an Albury-based prosecution team, Mr Jordan said he was "not really aware" of the decision to centralise those operations to capital cities.

"I'm not aware of what was the driver behind the prosecution function being here and not being here, but I think it is indicative of when you've got lots of really little groups in one site it might not be the most effective way to run the business," Mr Jordan said.

The tax office's adoption of new technology to assist business and personal clients was spruiked by Mr Jordan.

He said the ATO's app had been downloaded 600,000 times with users able to take photographs of receipts for deductions and link to Google maps to record trips.

Mr Jordan said the department was also expanding its voice authentication technology which allows taxpayers to leave a voiceprint with the ATO.

He said 1.1 million had been recorded, meaning details do not have to recited upon every contacted with the ATO.

Voice authentication will be launched through smart devices later this month, Mr Jordan said.

He said the technology was aimed at making tax dealings easier and ensuring services were accessible around-the-clock.
