But Canberra accountants say this year's tax season is set to be even busier than normal, due to the large number of people working from home.

With taxpayers set to claim more expenses as a result of working away from the office this year, tax firms have said this year's returns were expected to be more involved than normal.

Andrew Fernance from tax firm RSM said while the due date for this year's tax return is October 31, many were expected to file their return as early as possible due to the impacts of coronavirus.

"People will be wanting to get their refunds quickly, and there'll be a big demand early in the financial year," Mr Fernance said.

"This year, given people are conscious they've spent more for work, due to working from home, they'll want to claim more because they know how much they've spent."

Among the expenses that can be claimed is an 80 cents per hour rate for each day spent working from home for all working from home expenses.

Alternatively, a 52 cents per hour rate can be claimed to the tax office for heating, cooling and lighting in addition to calculating the cost of larger items used for work such as phone and internet costs and stationery.

Workers who need to have close contact with other people in the wake of coronavirus measures can also claim deductions for gloves, masks, or hand sanitiser.

The tax office will automatically include information in the tax return for those on JobKeeper payments.

Mr Fernance said people were expected to claim more this year due to the various working-from-home expenses.

"Some people want to claim every single dollar they can, while others are nervous about getting audited and they go without it," he said. "Especially with everyone working from home, people have been keeping much better records."

Tax office assistant commissioner Karen Foat said it had been preparing for a large amount of early returns.

"We know that each year there are people that like to lodge early and we anticipate that this will be the case again this year, particularly for people who may be under financial stress," Ms Foat said.

"If an individual's situation has changed and they are now working from home, they may be able to claim items they were not able to claim previously."
