What is Division 293 Tax Calculator?
▾
Imagine you’ve had a stellar year at work. Maybe you landed a big promotion, secured a juicy bonus, or your side hustle finally took off. You’re feeling great, and you decide to do the smart thing by putting some extra money into your superannuation—your retirement nest egg—to save on tax. But then, a few months later, a surprise letter from the Australian Taxation Office (ATO) lands in your inbox. It’s a Division 293 tax bill. Suddenly, that warm, fuzzy feeling of financial success is replaced by confusion. What is this extra tax, and why are you being penalized for saving for your future? In plain terms, Division 293 is an extra 15% tax levied on super contributions made by high-income earners. Normally, when your employer puts money into your super, or when you make a pre-tax contribution yourself, that money is taxed at a flat, concessional rate of just 15%. This is a sweet deal compared to standard personal income tax rates, which can climb up to 45% (plus levies). However, the government decided that for people earning over $250,000 a year, this tax break is just a bit too generous. To level the playing field, Division 293 claws back some of that benefit by bumping your super contribution tax rate up to 30% on some or all of your contributions. How does this help you in your daily life? Knowing how Division 293 works stops you from getting caught off guard by an unexpected four-figure tax bill. It helps you make smart, calculated decisions about whether salary sacrificing into your super is still worth it (spoiler alert: it usually is, but the math changes!). By using our calculator, you can easily estimate if you are creeping close to that $250,000 threshold and plan your cash flow ahead of time, ensuring your hard-earned money stays exactly where it belongs—working for you.

How to Division 293 Tax Calculator
▾
- 1First, we add up your 'Division 293 income'. This isn't just your base salary—it includes your taxable income, reportable fringe benefits (like a company car), net investment losses (like negatively geared property), and your pre-tax super contributions.
- 2Next, we check if this combined total goes over the $250,000 threshold. If it's under, you can breathe a sigh of relief—no extra tax for you!
- 3If you do cross the line, we find the 'excess amount'—which is simply how far over the $250,000 limit your total combined income and super went.
- 4We then compare this excess amount with your total pre-tax (concessional) super contributions for the year. The tax applies to whichever of these two numbers is smaller.
- 5Finally, we multiply that smaller number by 15% to calculate your Division 293 tax bill.
- 6The ATO calculates this automatically after you lodge your tax return and your super fund reports its data, which is why the bill often arrives months later.
- 7Once the bill arrives, you get to choose how to pay: you can either pay it out of your own pocket (cash) or ask your super fund to pay it out of your retirement balance.
Worked Examples
▾
You only pay the extra tax on the portion of your contributions that sits above the $250,000 line.
Meet Sarah, who earned $240,000 this year and had $20,000 put into her super. Her combined total is $260,000, which is $10,000 over the limit. Because the $10,000 excess is smaller than her $20,000 contribution, she only pays the 15% tax on that $10,000 excess. Her Division 293 bill is $1,500.
When your base income alone is above $250,000, your entire pre-tax super contribution is subject to the extra tax.
David earns a base of $270,000 and has $30,000 in concessional super contributions. Since his base income alone is already over the $250,000 threshold, his entire $30,000 super contribution gets hit with the extra tax. The excess is $50,000, but since the contribution ($30,000) is smaller, he pays 15% on the full $30,000, resulting in a $4,500 tax bill.
Even with Division 293, salary sacrificing is still highly beneficial compared to paying top-bracket income tax.
Emma usually earns $215,000, but a great year landed her a $30,000 cash bonus, bringing her income to $245,000. She also salary sacrificed to reach a total of $30,000 in super contributions. Her combined total is $275,000, putting her $25,000 over the line. Her Division 293 tax is 15% of $25,000, which equals $3,750. Even with this extra tax, Emma still saved thousands compared to paying her top personal tax rate of 47% on that money!
Paying from your super preserves your cash flow today, but it reduces your compound growth for retirement.
Liam receives a Division 293 tax bill of $3,000. He doesn't want to dip into his everyday savings account to pay it, so he logs into his ATO online portal and elects to pay using his super fund. The ATO sends a release authority to his super fund, which pays the $3,000 directly to the ATO. Liam's personal bank account remains untouched, though his retirement balance is reduced by $3,000.
Real-World Applications
▾
High-earning professionals calculating whether to salary sacrifice extra income into super or invest it elsewhere.
Families planning their annual tax strategies to see if a spouse's bonus will trigger an unexpected Division 293 liability.
Contractors and business owners structuring their company distributions and super contributions to optimize their tax position.
Everyday savers deciding whether to pay their Division 293 tax bill using their personal savings or their superannuation balance.

Special Cases
▾
Defined Benefit Fund Members
For folks with defined benefit super accounts (common in government or military roles), the ATO uses a 'notional' contribution value rather than what was actually deposited. The great news is you often don't have to pay this tax immediately—you can defer it to a 'debt account' which is paid when you finally access your super.
Exceeding Your General Super Cap
If you accidentally contribute more than your annual concessional limit (like the $30,000 cap), those excess contributions are taxed at your standard personal marginal rate instead. Because they are already taxed at your full rate, the ATO won't double-dip and apply the Division 293 tax to those excess amounts.
Part-Year Residents and Expats
If you moved to or from Australia during the financial year, your Division 293 calculation can get a bit tricky. The ATO will generally only look at your Australian-sourced income, but foreign income earned while you were an Australian resident still counts. It's highly recommended to double-check your residency status to avoid overpaying.
One-off Windfalls (Selling a Business or Property)
If you have a massive one-off capital gain from selling an investment property or a business, this can temporarily spike your income and trigger a Division 293 tax bill for that year, even if your regular salary is well below $250,000.

Frequently Asked Questions
▾
Why did I get this Division 293 tax bill so long after the financial year ended?
It feels like a late surprise, but it's completely normal! The ATO can't calculate your Division 293 tax until they have processed both your personal tax return and your super fund's annual report. Since super funds often report their data late in the year, your bill can easily arrive 9 to 18 months after the financial year has wrapped up. It’s best to keep a little cash set aside if you suspect you've crossed the threshold.
Should I pay this bill out of my own pocket or let my super fund handle it?
There is no single right answer, as it depends on your current cash flow and long-term goals. Paying it out of pocket keeps your retirement nest egg intact, allowing your super balance to keep compounding and growing for the future. On the other hand, letting your super fund pay it preserves your immediate personal cash flow if you have other short-term expenses or debts to manage.
Does this mean salary sacrificing into my super is no longer worth it?
In almost all cases, salary sacrificing is still a highly effective strategy even with this tax. Without salary sacrificing, your top dollars would be taxed at your marginal rate of up to 47% (including the Medicare Levy). With Division 293, your super contributions are taxed at a combined rate of 30% (15% standard + 15% extra), which still gives you a significant tax saving of up to 17% on every dollar you contribute.
What happens if I miss the 60-day deadline to pay from my super?
If you want your super fund to pay the bill, you must submit your election to the ATO within 60 days of receiving the notice. If you miss this window, the ATO will expect you to pay the bill personally using your own cash. If you don't pay it on time personally, they will start charging you general interest on the outstanding amount, so keep a close eye on that calendar!
Will my rental property losses or negative gearing help me avoid this tax?
Unfortunately, no! The ATO uses a very specific definition of income for Division 293, which actually adds back any net investment losses, including negative gearing on properties or shares. This is designed to prevent people from artificially lowering their income below the $250,000 mark through investment deductions.
Is the $250,000 threshold going to go up with inflation?
Sadly, the $250,000 threshold is not indexed to inflation or wage growth. This means that as wages naturally rise over time, more and more everyday professionals will find themselves crossing this threshold and receiving a Division 293 bill. This is why using our calculator regularly is a great way to stay ahead of the curve.
I have a defined benefit super fund. How does this affect me?
If you are in a defined benefit fund, the rules are a bit different and a lot more complex. Instead of looking at actual contributions, the ATO uses a 'notional' contribution amount calculated by your fund's actuary. While you still have to pay the tax, you might be able to defer the payment until you actually start receiving your super benefits, rather than paying it right away.
Common Mistakes to Avoid
▾
- !Assuming salary sacrifice is a waste of time once you hit the threshold—even with the extra 15% tax, you still save up to 17% compared to your top personal tax rate.
- !Forgetting that the 60-day election window to pay from your super is strict. If you miss it, you have to pay the tax out of your own pocket.
- !Neglecting to include your employer's super contributions when estimating if your total income will cross the $250,000 mark.
- !Not setting aside some cash or planning your cash flow for the delay, as Division 293 bills often arrive a year or more after you lodge your tax return.
Pro Tip
Keep an eye on your total income if you expect a big bonus or a capital gain from selling shares or property. If you know you're going to cross the $250,000 line, pre-plan whether you want to pay the upcoming Division 293 bill with your own cash or have your super fund pay it, so you aren't caught off guard when the ATO notice arrives!
Did you know?
When Division 293 tax was first introduced in 2012, it only targeted people earning over $300,000, affecting a small group of about 60,000 people. Because the threshold was lowered to $250,000 and has never been adjusted for inflation, more than half a million hard-working Australians now pay this tax every year!
