ATO finds billions in tax is unpaid by small business

Clarke McEwan Accountants

The small business tax gap currently stands at 12.5 per cent, or $11.1 billion, the first time the ATO has released a tax gap for the sector.

The figure is significantly larger than the corporate tax gap at $1.8 billion, or 4.4 per cent, and the individuals not in business tax gap at $8.7 billion, or 6.4 per cent.

The small business tax gap was estimated through the review of 1,398 randomly selected small business taxpayers for the 2015–16 income year, with an independent expert panel giving it a medium reliability rating.

There are approximately 6 million small business entities in Australia, made up of 4 million small businesses, plus all of the associated individuals that are required to pay tax on the income generated by the businesses.

While 71 per cent of small businesses reported correctly, 18 per cent made mistakes despite trying to comply, 7 per cent under-reported income or exaggerated expenses, and 4 per cent deliberately avoided paying the right tax. While only 4 per cent of the taxpayers in the sample were clearly identified as exhibiting black economy behaviour, the adjustments made to their tax returns accounted for over 60 per cent of the total value of adjustments.

With nine out of 10 small businesses in the sample using a tax professional to manage their tax affairs, in line with the 96 per cent figure touted with the broader small business population, ATO deputy commissioner Deborah Jenkins believes the profession can do more to help reduce the tax gap.

"While we've got a great result here and that so many small businesses are doing the right thing and trying to do the right thing with the help of their tax adviser, if [advisers] don't ask the right questions and they don't engage with them, it is their reputation that is at risk," Ms Jenkins told Accountants Daily.

"Part of the gap is down to the tax profession, but they are part of the team and we are in partnership with them to help small businesses get it right."

Main tax gap issues

According to the ATO, the main drivers of the tax gap include businesses not declaring all income, failing to account for private use of business assets or funds and not understanding their tax obligations.

Ms Jenkins believes accountants can help shrink the gap by proactively engaging with clients on a regular basis and exercising due diligence and probing deeper when receiving information from clients.

"Some tax agents understand the tax obligations of the business, but they don't actually ask enough about what's going on in the business. We really encourage those tax professionals to get to understand the business that they are providing these services to and not just be the form filler and putting numbers in a box," Ms Jenkins said.

"Don't just take things at face value. If it doesn't look right, if it looks like your client is living beyond their means, if you are seeing their books come through and they don't have a lot of income there but they are having holidays overseas, children in private school, ask the question again and the reason I say this is because it is their reputation that is on the line.

"Whether they are a chartered accountant, a CPA or an IPA, they are on the hook and they are also participating in this if they don't ask the questions."

'The yardstick is reasonable care'

The Institute of Public Accountants general manager of technical policy, Tony Greco, said that while the tax gap figure was large, it would be potentially larger without the help of tax professionals.

" The ATO concurs that most small businesses are getting it right with the aid of their tax professional , but we also have to acknowledge that this is a wake-up call and ask if we are doing enough - are we scrutinising client records enough, are we asking enough probing questions and questioning client assertions," Mr Greco said.

"Ninety-six per cent of small businesses use a tax professional, so we also have to accept that we have a role to play in this gap."

However, Mr Greco said it would be unwise to pin the blame squarely on tax professionals , noting that it was impossible for accountants to be the "eyes and ears" of the business.

"At the end of the day, we have to rely on what the client tells us," Mr Greco said.

"We can't audit everything, we're not there as auditors and we could never fulfil that role, but that doesn't mean we switch off any red flags - if something doesn't make sense, we have to challenge those assertions.

"The yardstick is called reasonable care. If the red flags are there and accountants accept the information, then that is not exercising due diligence and we have to accept some responsibility."

Likewise, CPA Australia general manager of external affairs Paul Drum said accountants could not go beyond the remit of their engagement.

"The law requires a tax agent to take reasonable care and that means they do make reasonable enquiries as part of their engagement with the clients to the extent of the client agreement," Mr Drum said. "It doesn't mean every engagement with a client is going to be a full audit of a client's affairs. In the case of tax return preparation, it is far beyond the remit of what the engagement with the client is about."

Editor's note: At Clarke McEwan it is our commitment to clients and part of our engagement that we advise the client if any material weakness in the their accounting system or internal control systems comes to our notice.

What’s changed? Old rate: 11.5% (up to 30 June 2025) New rate: 12% (from 1 July 2025) This increase affects cash flow, payroll accruals and employment contracts, especially where total remuneration includes superannuation. Employer checklist Update payroll software: ensure systems are calculating 12% SG correctly from 1 July 2025 pay runs. Review employment agreements: if contracts are set to inclusive of super, the take-home pay of employees may reduce unless renegotiated or the employer decides to bear the cost of the increased SG rate. Budget for higher super contributions: consider possible cash flow impacts. Remember that significant penalties can be imposed for late or incorrect SG payments, including loss of deductions, interest and other administration charges. Personal superannuation contributions The annual concessional contribution cap will remain at $30,000 for the 2025/2026 financial year. The annual non-concessional contribution (NCC) cap is set at four times the concessional contribution cap meaning it will also remain at $120,000. Although the annual NCC cap has not changed, NCCs can now be made by individuals with a total super balance (TSB) of less than $2,000,000 on 30 June 2025 (assuming they have not reached the age 75 deadline and any prior bring forward periods are considered). This is due to the fact that the upper TSB limit links to the general transfer balance cap (TBC) which has increased to $2,000,000. Personal deductible contributions A superannuation fund member may be able to claim a deduction for personal contributions made to their super fund with personal after-tax funds. A member will normally be eligible to claim a deduction if: The member makes an after-tax contribution to their superannuation fund in the relevant financial year. They are aged under 67 or 67 to 74 and meet a work test or work test exemption. They have provided the superannuation fund with a valid notice of intent to claim. The super fund has provided the member with acknowledgement of the notice of intent to claim. Notice of intent to claim If the member is eligible and would like to claim a deduction, then they must notify their super fund that they intend to claim a deduction. The notice must be valid and in the approved form – Notice of Intent to Claim or vary a deduction for personal super contributions (NAT 71121). The tax legislation provides a notice of intent to claim will be valid if: • The individual is still a member of the fund • The fund still holds the contribution • It does not include all or part of an amount covered by a previous notice • The fund has not started paying a super income stream using any of the contribution • The contributions in the notice of intent have not been released from the fund that the individual has given notice to under the FHSS scheme • The contributions in the notice of intent don't include FHSSS amounts that have been recontributed to the fund. What you need to consider The member must provide the notice of intent to claim to the fund by the earlier of: • The day the individual lodges their income tax return for the relevant financial year; or  • 30 June of the following financial year in which the individual made the contribution. However, if a super fund member provides a notice of intent after they have rolled over their entire super interest to another fund, withdrawn the entire super interest (paid it out of super as a lump sum), or commenced a pension with any part of the contribution, the notice will not be valid. This means the individual will not be able to claim a deduction for the personal contributions made before the rollover or withdrawal.

Let’s take a look at the key features of the tax system dealing with luxury cars and the practical impact they can have on your tax position. Depreciation deductions and GST credits Normally when someone purchases a motor vehicle which will be used in their business or other income producing activities there will be an opportunity to claim depreciation deductions over the effective life of the vehicle. Rather than claiming an immediate deduction for the cost of the vehicle, you will typically be claiming a deduction for the cost of the vehicle gradually over a number of years. Likewise, a taxpayer who is registered for GST might be able to claim back GST credits on the cost of purchasing a motor vehicle that will be used in their business activities. However, when you are dealing with a luxury car the tax rules will sometimes limit your ability to claim depreciation deductions and GST credits, impacting on the after-tax cost of acquiring the car. How does it work? Each year the ATO publishes a luxury car limit which is $69,674 for the 2025-26 income year. If the total cost of the car exceeds this limit, then this can impact the GST credits or depreciation deductions that can be claimed. Let’s assume that Alice buys a new car for $88,000 (including GST) in July 2025. To keep things simple, let’s say Alice uses the car solely in her business activities and is registered for GST. The first issue for Alice is that rather than claiming GST credits of $8,000, her GST credit claim will be limited to $6,334 (ie, 11th x $69,674). We then subtract the GST credits that can be claimed from the total cost, leaving $81,666. As this still exceeds the luxury car limit, Alice’s depreciation deductions will be capped as well. While she actually spent $89,000 on the car, she can only claim depreciation deductions based on a deemed cost of $69,674. The end result is that Alice has missed out on some GST credits and depreciation deductions because she bought a luxury car. Exceptions to the rules There are some important exceptions to these rules. The rules only apply to vehicles which are classified as ‘cars’ under the tax system. That is, the car limit doesn’t apply if the vehicle is designed to carry a load of at least one tonne or it is designed to carry at least 9 passengers. The rules only apply if the vehicle was designed mainly for carrying passengers. The way we determine this depends on the nature of the vehicle and whether we are dealing with a dual cab ute or not. For example, let’s assume Steve buys a ute which is designed to carry a load of at least one tonne. This isn’t classified as a car for tax purposes so Steve won’t miss out on GST credits or depreciation deductions. However, let’s assume Jenny has bought a dual cab ute which is designed to carry a load of less than one tonne and fewer than 9 passengers. This is classified as a car and the luxury car limit will apply unless we can show that it wasn’t designed mainly to carry passengers. As we are dealing with a dual cab ute, we multiply the vehicle’s designed seating capacity (including the driver's) by 68kg. If the total passenger weight determined using this formula doesn’t exceed the remaining 'load' capacity, we should be able to argue that the ute wasn’t designed mainly for the principal purpose of carrying passengers, which means that Jenny should be able to claim depreciation deductions based on the full cost of the vehicle. The approach would be different if we were dealing with something other than a dual cab ute, such as a four-wheel drive vehicle. Luxury car lease arrangements Normally when someone enters into a lease arrangement for a car and they use the car in their business or employment duties there’s an opportunity to claim deductions for the lease payments, adjusted for any private usage. However, if the value of the car exceeds the luxury car limit then the tax rules apply differently. Basically, what happens is that the taxpayer is deemed to have purchased the car using borrowed money. Rather than claiming a deduction for the actual lease payments, instead we will be claiming deductions for notional interest charges and depreciation, subject to the luxury car limit referred to above. Luxury car tax Cars with a luxury car tax (LCT) value which is over the LCT threshold for that year are subject to LCT, which is calculated as 33% of the amount above the LCT threshold. The LCT thresholds for the 2025-26 income year are: $91,387 for fuel-efficient vehicles $80,567 for all other vehicles that fall within the scope of the LCT rules From 1 July 2025 the definition of a fuel-efficient vehicle has changed, meaning that a car will only qualify for the higher LCT threshold if it has a fuel consumption that does not exceed 3.5 litres per 100km (this was 7 litres per 100km before 1 July 2025). Buying a car or other motor vehicle can be a complex process and there will be a range of factors to consider.

The purpose of the loan The most important thing when looking at the tax treatment of interest expenses is to identify what the borrowed money has been used for. That is, why did you borrow the money? For interest expenses to be deductible you generally need to show that the borrowed funds have been used for business or other income producing purposes. The security used for the loan isn’t relevant in determining the tax treatment. Let’s take a very simple scenario where Harry borrows money to buy a new private residence. The loan is secured against an existing rental property. As the borrowed money is used to acquire a private asset the interest won’t be deductible, even though the loan is secured against an income producing asset. Redraw v offset accounts While the economic impact of these arrangements might seem somewhat similar, they are treated very differently under the tax system. This is an area to be especially careful with. If you have an existing loan account arrangement, you’ve paid off some of the loan balance and you then use a redraw facility to access those funds again, this is treated as a new borrowing. We then follow the golden rule to determine the tax treatment. That is, what have the redrawn funds been used for? An offset account is different because money sitting in an offset account is basically treated much like your personal savings. If you withdraw money from an offset account you aren’t borrowing money, even if this leads to a higher interest charge on a linked loan account. As a result, you need to look back at what the original loan was used for. Let’s compare two scenarios that might seem similar from an economic perspective: Example 1: Lara’s redraw facility Lara borrowed some money five years ago to acquire her main residence. She has made some additional repayments against the loan balance. Lara redraws some of the funds and uses them to acquire some listed shares. Lara now has a mixed purpose loan. Part of the loan balance relates to the main residence and the interest accruing on this portion of the loan isn’t deductible. However, interest accruing on the redrawn amount should typically be deductible where the funds have been used to acquire income producing investments. Example 2: Peter’s offset account Peter also borrowed money to acquire a main residence. Rather than making additional repayments against the loan balance, Peter has deposited the funds into an offset account, which reduces the interest accruing on the home loan. Peter subsequently withdraws some of the money from the offset account to acquire listed shares. This increases the amount of interest accruing on the home loan. However, Peter can’t claim any of the interest as a deduction because the loan was used solely to acquire a private residence. Peter simply used his own savings to acquire the shares. Parking borrowed money in an offset account We have seen an increase in clients establishing a loan facility with the intention of using the funds for business or investment purposes in the near future. Sometimes clients will withdraw funds from the facility and then leave them sitting in an existing offset account while waiting to acquire an income producing asset. This can cause problems when it comes to claiming interest deductions. First, even if the offset account is linked to a loan account that has been used for income producing purposes, this won’t normally be sufficient to enable interest expenses incurred on the new loan from being deductible while the funds are sitting in the offset account. For example, let’s say Duncan has an existing rental property loan which has an offset account attached to it. Duncan takes out a new loan, expecting to use the funds to acquire some shares. While waiting to purchase the shares, he deposits the funds into the offset account, which reduces the interest accruing on the rental property loan. It is unlikely that Duncan will be able to claim a deduction for interest accruing on the new loan because the borrowed funds are not being used to produce income, they are simply being applied to reduce some interest expenses on a different loan. To make things worse, there is also a risk that parking the funds in an offset account for a period of time might taint the interest on the new loan account into the future, even if money is subsequently withdrawn from the offset account and used to acquire an income producing asset. For example, even if Duncan subsequently withdraws the funds from the offset account to acquire some listed shares, there is a risk that the ATO won’t allow interest accruing on the second loan from being deductible. The risk would be higher if there were already funds in the offset account when the borrowed funds were deposited into that account or if Duncan had deposited any other funds into the account before the withdrawal was made. This is because we now can’t really trace through and determine the ultimate source of the funds that have been used to acquire the shares. To do It’s worth reaching out to us before entering into any new loan arrangements. In this area, mistakes are often difficult to fix after the fact, which can lead to poor tax outcomes. That’s why getting advice from a tax professional before committing to a loan is essential. We can work alongside you to ensure your loan is structured in a way that makes financial sense and protects your tax position.
