The ATO publishes occupation and industry specific guides for a range occupations which are useful to help find out the types of deductions that can be claimed for certain occupations.

To claim a work-related deduction:

you must have spent the money yourself and weren't reimbursed
it must directly relate to earning your income
you must have a record to prove it

If the expense was for both work and private purposes, you can only claim a deduction for the work-related portion. Work expenses reimbursed to you by your employer are not deductible.

Have a look to see if your occupation or industry has a guide and if you have any questions get in touch to find out how Momentum can help ensure you get your deduction claims right.
