Wagga's Boyce Chartered Accountants director Hamish Cullenward said there are constant changes to legislation and it is important for people to be up to speed before they lodge their return.

"Paying attention to the budget each year and the key outcomes (summarised by the Australian Tax Office on their website) can be a quick and easy way," Mr Cullenward said.

"Having a good relationship with your accountant and financial adviser is also a great way to keep on top of the changes and ensuring you are minimising tax and maximising wealth creation.

"The ATO are also coming out with new ways to engage the taxpayer and the ATO website is a great place to find out what is changing and what is available."

The ATO and local accountants have reported five main areas where people are incorrectly claiming:

ATO assistant commissioner Kath Anderson said people must claim temporary jobs or money they earned from the sharing economy, even if it was just a once-off.

"You must also include income from cash jobs, foreign income, capital gains on cryptocurrency, bank interest and any government payments," she said.

"We know some people lodge early because they want their refund, and that's fair enough.

"But every year we have to later amend returns for thousands of taxpayers because they left income out. And that can result in owing money back to the ATO."

Robert Fry, accountant at Adams and Associates, said many people fall into the trap of claiming things that are not necessarily related to people's work.

"Motor vehicle expenses and laundry are big ones that people tend to get wrong," Mr Fry said.

"In regards to laundry, there are only some specific type of work-related clothing that you can claim, such as occupation specific or protective clothing."

Similarly, Mr Cullenward said people are often not aware of what is deductible.

"This includes certain home office expenses, or what constitutes as 'work-related' by often claiming things the ATO considers personal in nature such as work travel, certain clothing and private phone use," he said.

Mr Cullenward said interest deductibility is also often misunderstood with interest being deductible based on the purpose of the funds rather than what the loan is secured against.

"For instance if you had a redraw facility with the original loan being secured against an investment property and the interest currently deductible against this investment income," he said.

"Then if you withdrew funds to make say a super contribution (or a purchase of a private nature) the interest relating to this portion of the loan would be non-deductible regardless of the loan being secured against the investment.

"With good planning you can pay off your non-deductible debt first maximising your interest tax deduction."

Ms Anderson said there will be consequences for those intending to "push the boundaries", or perhaps fudge some parts of their return.

"People need to be aware that the ATO has improved technology and access to even more data this year," she said.

"We scrutinise every return and we are increasing our investment, not just in education and assistance, but also in reviews and audits."

Rental property owners are being warned to ensure their claims are correct as the ATO announced it will double the number of audits scrutinising rental reductions.

Assistant commissioner Gavin Siebert said this year the ATO has made rental deductions a top priority.

"A random sample of returns with rental deductions found that nine out of 10 contained an error," he said.

According to the ATO, if you own a rental property, make sure you only claim deductions for times when your property was rented or genuinely available for rent, and only for loans where you used the proceeds on your rental property.

It also includes people claiming personal expenses associated with their rental property - like those who are claiming deductions for times when they are using their property for themselves and others who are claiming interest on loans used to buy personal assets like a car or boat.

In one case, a taxpayer was penalised over $12,000 for over-claiming deductions for their holiday home when it was not made genuinely available for rent, including being blocked out over seasonal holiday periods.

"Our message is clear: if you are renting out a room or a property, any money you earn must be declared as income and any deductions you claim may need to be apportioned for private use," assistant commissioner Mr Siebert said.

Despite many feeling that they already have enough life admin challenges, Mr Fry said a few simple steps can make life much easier by June 30.

"The most important thing is keeping records, but not too onerous," he said.

"The most crucial aspect is holding onto your receipts and maintaining good records."

Mr Cullenward offered additional tips for keeping on top of your tax:

If you've got all your information ready, Mr Fry said people can lodge their return early.

However, the ATO only receives all the information from banks and investments in regards to interest from mid-August, so for those without this information it might be worth waiting a month or so.
