As part of the economic stimulus measures, the federal government has included a couple of sweeteners for both businesses and individuals doing their tax returns this year.

One of the most notable is the extension of the "shortcut method" introduced in 2020, whereby people working from home can claim a blanket 80 cents per hour instead of the traditional tax return.

Those wanting to do it the old-school way can claim 52 cents per hour and put in a separate claim for other working-at-home expenses such as depreciation and travelling costs.

WDF Professional accountant Janita Croxton said there were a vast array of working-from-home expenses that could be claimed on tax for those using the fixed-rate method.

That includes phone and internet bills, cleaning costs, heating and air-conditioning, home office equipment, and printer ink - which can add up significantly.

"Keep receipts if you can, that's the biggest take-home message. If you're spending something, keep a receipt," Ms Croxton said.

"If you are coming in to see a tax agent of or you're coming in to see us and you're not sure about something, just bring everything in and we can evaluate it all.

"If you think something might be tax deductible, keep it and we can then determine whether it is or not."

This year the low income tax offset has been raised from $445 to $700, meaning that those in the low income bracket will get up to $700 in offsets.

Workers earning less than $37,500 will get the full $700, gradually tapering off until the $66,667 income range.

There has also been an increase to the low and middle income earner tax thresholds, meaning that those earning less than $90,000 can get a maximum tax benefit of $1080.

Taxpayers earning above $90,000 have a maximum tax benefit of $2430.

However, Charles Sturt University Wagga accountant lecturer Liza Byrnes said the biggest-ticket items this time around were business owners.

This year the government has introduced "temporary full expensing", which Ms Byrnes describes as "probably one of the boldest initiatives we have ever seen in relation to depreciation".

Under the changes, businesses with a turnover of less than $5 billion can fully tax deduct any new depreciating assets - a move designed to stimulate business growth post-lockdown.

Small and medium sized businesses with a turnover of less than $50 million can also fully deduct second-hand depreciating assets.

The balance of a 'small business entity' pool can be fully deducted where the business has a turnover of less than $10 million.

"Combined with the loss carry back rules, allowing corporate tax entities to carry back losses made in the 2020, 2021 and 2022 financial years to previous taxable years from 2019 onwards, temporary full expensing has the potential to create a significantly favourable tax outcome for business this year by creating losses and boosting cashflow," Ms Byrnes said.

Australia Taxation Office assistant commissioner Tim Loh said they would be keeping an eye out for those trying to rort their working-from-home expenses this year.

"While it's good to see most people have been doing the right thing, our data analytics will be on the lookout for unusually high claims this tax time. Particularly where someone's deductions are much higher than others with a similar job and income," Mr Loh.

"We will also look closely at anyone with significant working from home expenses, that maintains or increases their claims for things like car, travel or clothing expenses."
