With the 2026–27 Federal Budget introducing a proposed $1,000 standard work-related expenses deduction and a new $250 Working Australians Tax Offset (WATO), many taxpayers are asking an important question: what is the difference between a tax deduction and a tax offset?

While both can reduce the amount of tax you pay, they operate in very different ways and understanding the distinction can help you make more informed tax planning decisions.

What Is a Tax Deduction?

A tax deduction reduces your taxable income before your income tax is calculated.

Common tax deductions include:

  • Work-related expenses such as uniforms, tools and professional subscriptions.
  • Gifts and donations to deductible gift recipients (DGRs).
  • Investment property expenses.
  • Tax agent fees and other costs associated with managing your tax affairs.

For example, if you earn $60,000 and are entitled to claim $2,000 in deductions, your taxable income is reduced to $58,000. Tax is then calculated on the lower amount.

How Much Is a Deduction Worth?

The value of a deduction depends on your marginal tax rate.

As an example, a $1,000 deduction may reduce your tax by:

  • Approximately $160 if your marginal tax rate is 16%.
  • Approximately $300 if your marginal tax rate is 30%.

In other words, the higher your tax bracket, the greater the benefit you receive from a deduction.

What Is a Tax Offset?

A tax offset works differently. Rather than reducing your taxable income, it directly reduces the amount of tax payable after your tax has been calculated.

Many taxpayers already benefit from offsets such as:

  • The Low Income Tax Offset (LITO).
  • The Seniors and Pensioners Tax Offset (SAPTO).
  • The Private Health Insurance Rebate.
  • The Spouse Superannuation Contribution Tax Offset.

For example, if your taxable income results in a tax liability of $1,888 and you qualify for a $700 tax offset, your final tax payable is reduced to $1,188.

Why Offsets Are Often More Valuable

The key advantage of a tax offset is that it reduces your tax bill dollar-for-dollar.

A $1,000 tax offset generally reduces your tax payable by $1,000.

By comparison, a $1,000 tax deduction only reduces your taxable income by $1,000. The actual tax saving depends on your marginal tax rate and may be significantly less than $1,000.

This distinction is one reason the Government’s proposed introduction of both a standard deduction and a new tax offset has attracted considerable attention.

Are All Tax Offsets Refundable?

Not necessarily.

Most tax offsets are non-refundable, meaning they can reduce your tax liability to zero but cannot create a refund beyond the tax you owe.

For example, if your tax liability is $500 and you are entitled to a $700 non-refundable offset, the offset can only reduce your tax to nil. The unused $200 is generally lost.

Some offsets and rebates, however, may be refundable, allowing taxpayers to receive the benefit even if they have little or no tax payable.

Planning Ahead

Although the newly announced Budget measures are not expected to apply to 2025–26 tax returns, now is a good time to review your tax position.

Consider whether you are:

  • Claiming all deductions you are entitled to.
  • Receiving all available tax offsets.
  • Keeping appropriate records to support your claims.

While the ATO automatically calculates certain offsets, such as the Low Income Tax Offset, others must be claimed when lodging your tax return.
