What Software Engineers Can Claim

Software engineers frequently invest in their professional growth through courses, certifications, and conferences. These expenses are deductible if they directly relate to maintaining or improving skills for your current job.
- Online courses and certificationsVaries, e.g., ~$500-$2,000/course

Purchase of technical books, journals, or subscriptions to professional development platforms (e.g., O'Reilly, LinkedIn Learning) that improve your work-related skills.

- Specialised software licensesVaries, e.g., ~$50-$300/year
Costs for software tools essential for your work that your employer doesn't provide or reimburse, such as IDEs, code editors, or design software, are deductible.

Other small IT accessories like webcams, docking stations, or specific cables used for work, provided they are not supplied by your employer.
Receipt required - Depreciation of personal laptop/desktopVaries, based on cost and work use percentage
If you use your personal laptop or desktop computer for work, you can claim a percentage of its depreciation based on its work-related use. Keep a logbook or reasonable estimate of usage.

Home Office
For software engineers who regularly work from home, a portion of their home office expenses can be claimed. The ATO's fixed-rate method is often the simplest for most.
- Running costs (fixed rate method)70¢/hour
Claim 70 cents per hour for every hour you work from home, covering energy, internet, and stationery. No need for receipts for these specific items, but you must keep a record of your hours.
No receipt needed - Depreciation of office furnitureVaries, e.g., ~$150-$800/item
Cost of a desk, ergonomic chair, or filing cabinet specifically for your home office. Items under $300 are fully deductible; over $300 are depreciated.
Receipt required - Work-related stationeryVaries, e.g., ~$20-$100/year
Purchases of stationery items like pens, notebooks, or printer paper used for your work at home, if not covered by the fixed-rate method (i.e., if claiming actual costs).
Receipt required
Phone & Internet
If you use your personal phone or home internet for work purposes, you can claim a portion of these expenses, especially if you're regularly communicating with colleagues or accessing work systems remotely.
- Work-related phone calls & dataVaries, e.g., ~20-50% of bill
You can claim the work-related portion of your personal mobile phone bill. Keep a logbook for a typical four-week period to determine your percentage of work use.
Receipt required - Work-related home internetVaries, e.g., ~30-70% of bill
The work-related portion of your home internet costs. As with phone, keep a logbook for a typical four-week period or provide a reasonable estimate of work-related usage (e.g., if primarily used for WFH).
Receipt required
Other Work-Related
This category covers miscellaneous expenses directly related to your employment as a software engineer that don't fit neatly into other categories.
- Professional indemnity insuranceVaries, e.g., ~$500-$2,000/year
If you are a contractor or self-employed and required to hold professional indemnity insurance, the premiums are deductible.
Receipt required - Donations to industry-related charitiesVaries
Donations of $2 or more to DGR (Deductible Gift Recipient) organisations that support technology education or industry development are deductible.

Special Situations for Software Engineers
Contract Software Engineers
As a contract software engineer, you may have additional deductible expenses, such as specific business insurance, accounting fees for business activity statements (BAS), and a broader range of home office expenses if you operate solely from home as a sole trader. Ensure you understand the distinction between employee and contractor deductions.
Relocation for work
If you permanently relocate for a new job, generally, moving expenses (e.g., removalist costs, travel to the new location) are not deductible. However, if your employer reimburses these, they are usually tax-free, so check your employment agreement.
Common Mistakes Software Engineers Make
| Mistake | What to do instead |
|---|---|
| Claiming the entire cost of personal devices or internet/phone bills. | Only the work-related portion is deductible. Keep a logbook for a typical four-week period to determine your percentage of work use for personal devices and services. |
| Forgetting to claim small, regular expenses. | Even small items like stationery, software subscriptions, or a portion of your home internet add up. Keep all receipts, no matter how small. |
| Claiming self-education for a job you're trying to get, not your current one. | Self-education expenses are only deductible if they directly relate to your CURRENT employment and help you maintain or improve skills, or result in an increased income in that role. |
| Not keeping records for home office hours. | If using the fixed-rate method for working from home (70 cents per hour), you must keep a diary or logbook of the actual hours you worked from home. Electronic records are acceptable. |
| Incorrectly claiming depreciation for items over $300. | Items costing more than $300 (e.g., a high-end monitor, an expensive ergonomic chair) must be depreciated over their effective life, not claimed in full in the year of purchase. Your tax agent can assist with this. |

Frequently Asked Questions
Can I claim my subscription to a gaming service or entertainment streaming while working from home?
No, entertainment or gaming subscriptions are generally considered private expenses and are not deductible, even if you use them on a device you also use for work. Only services with a direct work-related purpose are claimable.
What if my employer reimburses me for some expenses?
If your employer reimburses you for an expense, you generally cannot claim it as a deduction. This would be considered double-dipping. Ensure you only claim expenses that you paid for yourself and were not reimbursed.
Do I need receipts for every single deduction?
Generally, yes. For most work-related expenses, you need to keep records like receipts, invoices, or bank statements for five years. Exceptions exist for minor claims like laundry under $150 or specific home office costs under the fixed-rate method, but accurate records are always best practice.
Can I claim the cost of my home rent or mortgage interest if I work from home?
No, as a salaried or contractor software engineer working from home, you generally cannot claim occupancy expenses like rent, mortgage interest, property insurance, or rates. These are only for those operating a business from a dedicated home office space.
I purchased a new high-performance computer for my personal use, but I also use it for coding on the side. Can I claim it?
You can claim a percentage of the depreciation of the computer based on its work-related use. If it's primarily for personal use and only occasionally used for work, the deductible portion will be small. Keep a logbook to justify your work-related percentage.
What's the difference between the fixed-rate method and actual cost method for home office expenses?
The fixed-rate method (70 cents/hour) covers electricity, gas, internet, phone, and stationery, requiring only a record of hours. The actual cost method allows you to claim a percentage of your actual bills (electricity, phone, internet) plus depreciation for office furniture and equipment, but requires more detailed record-keeping and apportionment calculations.
Quick Checklist
- Keep all receipts and invoices for work-related expenses.
