THOUSANDS of Curtis Island workers who may have made false claims on their tax returns have been given a chance to avoid a hefty fine.
With help from Bechtel, the Australian Taxation Office generated a Bechtel Curtis Island-specific fact sheet that was sent out to 10,000 workers.
It came after the "local community raised concerns" that some workers were wrongly claiming work-related expenses, the tax office said.
Workers may have been given incorrect advice, and the tax office will now work with tax agents and their clients to clarify the law.
The Observer understands some of those people could be required to repay up to $10,000, although the tax office has confirmed that if tax returns including for previous years are resubmitted before October 31, no penalties will apply.
The fact sheet guides employees on the deductions they can and can't claim, and outlines rules around mobile phones, accommodation, allowances and training courses.
Workers can contact the ATO for advice on 132861.
