Receipt required - Specialised Software Subscriptions$500-$2,000+/year
Subscriptions for engineering design software (e.g., AutoCAD, Revit, structural analysis programs) if you pay for them yourself and use them for work. Keep detailed records of business use.
Receipt required - Measuring Tools & Hand Tools
Costs for personal measuring tapes, levels, calculators, or small hand tools that you are required to provide for your work on site. Items under $300 are immediately deductible.

Deductions for using your personal vehicle for work-related travel, such as site visits, and other travel expenses.
- Work-Related Car Travel (Cents Per Kilometre)88¢/km (max 5,000km)
Claim up to 5,000 work-related kilometres per year using the fixed rate of 88 cents per kilometre for FY2025-26. This covers travel between different work sites, client meetings, or training. Keep a logbook or diary for distances.
No receipt needed - Work-Related Car Travel (Logbook Method)
If you travel more than 5,000 work-related kilometres, you must use a logbook for 12 continuous weeks to determine your business use percentage. You can then claim a percentage of all car expenses (fuel, insurance, registration, depreciation, maintenance).
Receipt required - Parking & Tolls
Out-of-pocket expenses for parking and tolls incurred during work-related travel (e.g., site visits, client meetings). Excludes regular travel from home to work.
Receipt required - Public Transport Fares

Receipt required

No receipt needed - Work-Related Phone Expenses (Actual Costs)
If you don't use the fixed rate method, you can claim the work-related portion of your mobile phone bill. You'll need to analyse your bill for a representative four-week period to determine your business use percentage.

Similar to phone expenses, if not using the fixed rate, you can claim the work-related portion of your home internet bill. Calculate the percentage of time spent using the internet for work.
Receipt required - Decline in Value of Office Furniture & Equipment
If you use the actual cost method for home office expenses, you can claim the depreciation (decline in value) of items like a desk, office chair, or filing cabinet if purchased for work and not fully claimed in the year of purchase (i.e., over $300).

Special Situations for Civil Engineers
Consulting Engineers (Sole Traders)
If you operate as a sole trader, you may be able to claim a broader range of business expenses, including business registration fees, public liability insurance, professional indemnity insurance, and a full range of home office expenses using the actual cost method, which can be more complex.
Working in Remote Locations/Fly-in, Fly-out (FIFO)
If you work in remote locations or FIFO, specific deductions may apply for accommodation, meals, and travel expenses if you are required to sleep away from home for work and your employer does not reimburse these costs. Keep meticulous records and check ATO rules carefully.
Professional Development Leave
If you take unpaid professional development leave, expenses incurred during this period (e.g., course fees, travel) may still be deductible if they are directly related to your ongoing employment as a civil engineer.
Common Mistakes Civil Engineers Make
| Mistake | What to do instead |
|---|---|
| Claiming home-to-work travel. | Travel from home to your primary workplace is generally considered private travel. Only travel between different work sites, or from home to an alternate work location (like a client's office or a construction site) and then back to your primary workplace or home, can be claimed. |
| Not keeping records for small claims. | Even for minor expenses like parking or tolls, if you're claiming the actual cost, a receipt or a detailed logbook entry is required. For vehicle cents-per-kilometre, a diary of trips is essential. |
| Double-dipping on home office expenses. | If you use the fixed rate method of 70 cents per hour for working from home, you cannot also claim separate deductions for electricity, gas, phone, internet, or the decline in value of office furniture (as these are included in the rate). Choose the method that yields the best outcome and claim accordingly. |
| Claiming items reimbursed by employer. | You cannot claim expenses that your employer has already reimbursed you for. Only out-of-pocket expenses are deductible. |
| Claiming personal grooming or general clothing. | Everyday clothing, even if worn for work, and costs for personal grooming (haircuts, makeup) are not deductible. Only specific protective clothing or occupation-specific uniforms with logos are claimable. |

Records to Keep
The ATO requires you to keep records for 5 years from your lodgement date. FY2025-26 receipts should be kept until 31 October 2031. Acceptable formats: original paper receipts, photos or scans (digital copies are accepted), bank or credit card statements, and logbooks for vehicle and WFH claims.
Frequently Asked Questions
Can I claim the cost of my university degree if I'm already a Civil Engineer?
Yes, if the course directly relates to your current employment and maintains or improves the specific skills required for your job, or is likely to result in an increase in your income from your current employment. For example, a Master's in Structural Engineering would likely be deductible. If it's to gain a new employment, it's generally not deductible.
How do I prove my work-related car travel?
For claims up to 5,000km using the cents-per-kilometre method, you need to show how you calculated the kilometres, such as a diary of work-related trips. For claims exceeding 5,000km using the logbook method, you need a 12-week logbook to determine your business use percentage, plus receipts for all car expenses.
What's the best way to claim home office expenses?
For most Civil Engineers, the fixed rate method (70 cents per hour for FY2025-26) is the simplest, as it covers many common costs without needing separate receipts. However, if your actual expenses (like internet, phone, and depreciation of expensive office equipment) for work are significantly higher, the actual cost method might yield a larger deduction but requires meticulous record-keeping.
Are meals deductible if I'm working late or on a site visit?
Generally, ordinary meals are not deductible, even if you're working overtime or on a site visit, as they are considered a private expense. Meals are only deductible if you are required to travel overnight and sleep away from home, or in very specific circumstances where you receive a travel allowance that's reported on your income statement.
Do I need receipts for everything?
Yes, for almost all expenses, you need a record, such as a receipt or invoice, to substantiate your claim. Exceptions include small claims like laundry expenses under $150 (though it's best practice to still keep proof of purchase for uniforms) and claims made using fixed rates, where a logbook or diary suffices (e.g., vehicle cents per km, home office hours).
Quick Checklist
- Gather all receipts and invoices for professional memberships and registrations.
- Collate records for any self-education courses, books, or technical subscriptions.
- Collect receipts for purchases of PPE, tools, or work-related tech (e.g., laptops, software).
- Maintain a diary or logbook for all work-related vehicle travel, including kilometres and purpose.
- Record all out-of-pocket parking and toll costs.
- Keep a log of hours worked from home if claiming home office expenses.
- Find receipts for union fees and income protection insurance premiums.
- Locate the invoice for your previous year's tax agent fees.
- Ensure all claims are for expenses you paid yourself and were not reimbursed by your employer.
- Review your bank statements for any smaller work-related purchases you might have overlooked.
