If you’ve ever wondered why some tax offsets reduce your tax refund while others put actual cash back in your pocket, you’re not alone. The key difference boils down to whether the offset is refundable or non-refundable. In simple terms:
- Refundable tax offsets can give you a refund even if you don’t owe any tax.
- Non-refundable tax offsets only reduce the amount of tax you owe ,if you don’t owe tax, you won’t get any cash back.
In this article, we’ll break down these two types of offsets in plain English, helping you understand how they work, when they apply, and why they matter to your tax return.
What is a Tax Offset?
Before diving into refundable and non-refundable types, let’s clarify what a tax offset is. A tax offset (also called a tax rebate) reduces the amount of income tax you pay. Unlike deductions, which reduce your taxable income, offsets directly reduce the tax you owe.
For example, if your tax bill is $5,000 and you have a $500 tax offset, your tax liability becomes $4,500.
Non-Refundable Tax Offsets
How Non-Refundable Offsets Work
Non-refundable tax offsets reduce your tax payable but cannot generate a refund if your tax payable is already reduced to zero.
Let’s say you owe $400 in tax, but you qualify for a $600 non-refundable offset. The offset will only reduce your tax bill to zero ,you won’t get the remaining $200 as a cash refund.
Common Non-Refundable Offsets in Australia
Some common examples include:
- Low and Middle Income Tax Offset (LMITO) – now phased out after 2021-22 but still relevant for past returns.
- Low Income Tax Offset (LITO) – reduces tax for low-income earners but is non-refundable.
- Private Health Insurance Rebate – may reduce your tax if you didn’t claim it as a premium reduction.
These offsets are designed to ease your tax burden, but they won’t put extra cash in your hand if your tax bill is already wiped out.
Refundable Tax Offsets
How Refundable Offsets Work
Refundable tax offsets are the ones taxpayers love. If the offset exceeds your tax payable, you get the leftover amount paid to you as a cash refund.
For example, if you owe $300 in tax but have a $500 refundable offset, you’ll not only reduce your tax bill to zero, but you’ll also get the extra $200 as a refund.
Common Refundable Offsets in Australia
Refundable offsets are rarer in Australia but highly valuable when they apply. Examples include:
- Franking Credits (Dividend Imputation Credits) – excess credits are refunded if they exceed your tax liability.
- Certain Withholding Tax Credits – such as amounts withheld under the PAYG system or from interest/dividends.
Franking credits are especially important for retirees and self-funded investors, as they often result in cash refunds.
Key Differences Between Refundable and Non-Refundable Tax Offsets
| Feature | Refundable Offset | Non-Refundable Offset |

| Common examples | Franking credits | LITO, Private Health Insurance Rebate |
Why This Matters to Your Tax Return
Understanding these offsets can help you:
- Maximise your refund – by ensuring you claim all available refundable offsets.
- Plan effectively – especially if you receive dividend income or other income with franking credits.
- Avoid disappointment – by knowing that some offsets will not result in cash back.
For example, if you’re a retiree heavily invested in Australian shares, knowing how refundable franking credits work can make a significant difference to your yearly cash flow.

Final Thoughts
Refundable and non-refundable tax offsets are powerful tools in the Australian tax system, but understanding the difference is essential. Refundable offsets can lead to real cash refunds, while non-refundable offsets can only reduce your tax to zero. Knowing how these apply to your situation helps you get the most out of your tax return.
