Intro

FIFO workers often assume allowances are automatically tax-free or deductible — they aren’t.

The ATO treats overtime, bonuses and most allowances as normal income first, then looks at whether a real work expense exists.

That’s why two workers earning the same allowance can have completely different deductions.

For a complete overview of FIFO tax rules and deductions, see the full FIFO Tax Guide 2026.

Are FIFO overtime payments taxed?

Yes.

Overtime is treated exactly the same as normal wages.

Higher tax just comes from earning more in that pay cycle — not a special overtime tax rate.

You cannot “claim tax back” just because you worked overtime.

You can only claim expenses you needed to earn that overtime income (for example protective equipment or union fees).

FIFO allowances explained (the part people misunderstand)

There are three types of allowances:

1) Fully taxable allowances (most common)

Examples:

• Site allowance
• Industry allowance
• Height allowance
• Dirt allowance
• Tool allowance (without receipts)

These allowances are usually treated as taxable income. Receiving them does not automatically mean you can claim the same amount as a deduction.

2) Allowances you MAY claim against

You can claim a deduction only if you actually spent the money:

• Travel allowance (when travelling for work)
• Overtime meal allowance (with receipt or within ATO reasonable amount)

If you didn’t spend it → no deduction.

3) Reimbursements (not income)

If your employer repays exact costs:

• Flights booked by company
• Accommodation paid directly
• Work transport provided

You cannot claim anything because you paid nothing.

FIFO bonuses — how tax works

Bonuses are treated as income in the year received.

They may be taxed higher in that payslip due to withholding calculations, but at tax return time they are taxed at your normal marginal rate.

You cannot offset a bonus unless a real deductible expense exists.

When FIFO workers CAN claim deductions

You may claim expenses related to earning income, such as:

• Protective clothing & PPE
• Union fees
• Training & tickets
• Travel between worksites
• Work-related travel expenses

But not private or living costs.

Different rules apply when travelling between job locations during a swing — see our guide on travel between worksites.

Some expenses like tools and equipment are separate deductions explained here.

You should also understand the rules around flights to site and meals and accommodation because many allowances relate to travel or living costs.

What FIFO workers usually cannot claim

• site allowance just because it was paid
• meals provided at camp
• accommodation at a regular rostered site
• travel from home to a regular worksite
• flights to and from a regular FIFO site

Overtime meal allowance rule (common audit trigger)

You can claim meals ONLY if:

• You received an overtime meal allowance
• You worked overtime
• You bought a meal
• You kept a receipt OR stayed within ATO reasonable amount

Miss one of these requirements and the claim may be denied.

These rules are different from normal living expenses explained in our meals and accommodation guide.

Common FIFO tax mistakes

Many FIFO workers overclaim deductions because they misunderstand how the ATO defines travelling for work vs living at work.

Common mistakes include claiming camp meals, claiming flights to a regular rostered site, or assuming allowances automatically create deductions.

Understanding these differences is important because most FIFO tax return adjustments happen in these areas.

Many workers forget they can also claim phone and internet deductions if they contact supervisors or receive rosters on their personal device.

Summary

Overtime, allowances and bonuses increase taxable income — they are not automatic deductions.

FIFO workers can only claim expenses they actually paid to earn that income, not living or roster costs.
