Tradie Tax Record Keeping Guide 2025-26
How to ATO-proof your tradie tax return with proper receipts, logbooks, diaries, and digital records.
Good record keeping is the difference between a smooth tax return and a stressful ATO audit. For tradies, the ATO expects clear documentation of tool purchases, vehicle use, site travel, PPE, licences, and work-related expenses. This guide covers exactly what you need to keep, how long to keep it, and how to organise it so you never lose a deduction.
Why Record Keeping Matters for Tradies
Tradies are a high-focus group for ATO audits. Why? Because you typically have more deductions than most professions โ tools, vehicles, PPE, travel, licences โ and the ATO knows that many tradies claim without proper records. If you can't substantiate a claim when audited, the ATO will disallow it, and you'll owe the tax, plus interest, plus penalties.
The 5-Year Record Retention Rule
The ATO requires you to keep all tax records for 5 years from the date you lodged your return (or the date it was due, whichever is later). This applies to every document supporting your claims:
- Receipts for tools, PPE, and equipment
- Vehicle logbooks and mileage records
- Work diaries for travel and phone use
- Bank and credit card statements showing purchases
- Invoices for licences, courses, and union fees
- Employer payment summaries and payslips
- Rental property records (if applicable)
After 5 years, you can safely dispose of them โ unless the ATO has specifically asked about them or there's a dispute in progress.
The $300 Threshold Explained
The $300 threshold is one of the most important rules for tradie tax. It determines whether you can claim a tool or work item as an immediate deduction without a receipt:
| Item Cost | Receipt Required? | How You Claim |
|---|---|---|
| Under $300 | No (but keep one anyway) | Full cost in one year โ instant write-off |
| $300 or more | Yes โ must have itemised receipt | Depreciate over effective life |
The threshold applies per individual item, not per total purchase. Buying a $250 saw and a $280 drill in the same trip means both qualify as instant write-offs. Buying one $350 saw means it must be depreciated.
Vehicle Logbook Requirements โ 12 Weeks
If you use the logbook method to claim vehicle expenses, you must keep a logbook for a continuous minimum 12-week period that represents your typical usage pattern. Once established, the logbook is valid for 5 years unless your circumstances change significantly (e.g. you change jobs, change vehicles, or your work-travel pattern shifts by more than 10%).
For each trip in the logbook, record:
- Date of the trip
- Starting and finishing odometer readings
- Destination and purpose (e.g. "Site 12 Smith St to Site 7 Jones Ave โ electrical rough-in")
- Kilometres travelled
- Whether it was a work or personal trip
The logbook method lets you claim a percentage of all vehicle costs (fuel, rego, insurance, maintenance, depreciation) based on your work-use percentage. Most tradies with a work ute achieve 60โ80% work use.
Fuel Receipts
If you use the cents-per-km method (88ยข/km, up to 5,000 km/year), you do not need fuel receipts โ you simply claim a flat rate per kilometre. This is the simplest option for tradies who only travel between sites occasionally.
If you use the logbook method, you need all fuel receipts to calculate your total vehicle expenses. Keep every receipt from the bowser. The ATO also accepts bank and credit card statements showing fuel purchases, but itemised receipts are better because they show the litres and fuel type.
Tool Receipts
Your tool receipts are the single most important records for your tradie tax return. The ATO expects to see:
- Supplier name and ABN โ Bunnings, Total Tools, Sydney Tools, TradeTools, etc.
- Date of purchase
- Item description โ "Makita 18V Impact Driver" not just "tool"
- Amount paid
- Payment method โ card, cash, account
For items under $300, keep receipts if you can. For items $300 and over, you must keep them. If you buy from Facebook Marketplace, cash sales, or second-hand, make a diary note at the time of purchase including the seller's details and a description of the item.
Phone Diary โ 4 Weeks
If you claim work-related phone and internet expenses, the ATO recommends keeping a 4-week diary to establish your work-use percentage. This applies whether you're claiming a portion of your phone plan or the cost of a new phone.
For 4 consecutive weeks, record:
- Number of work calls and their duration
- Number of personal calls and their duration
- Data used for work purposes (emails, rostering apps, quoting software)
- Data used for personal purposes
At the end of the 4 weeks, calculate your work-use percentage. For most tradies, this falls between 20โ50%. That percentage applies to your phone plan costs for the full year. The diary is valid for the life of your plan unless your work patterns significantly change.
myDeductions App โ Your Digital Record Keeper
The ATO's free myDeductions app (available on iOS and Android) is designed for exactly this purpose. It lets you:
- Snap a photo of any receipt and categorise it
- Record odometer readings for vehicle logbook
- Log work-related trips with GPS
- Store bank records and invoices
- Export a summary report for your tax agent at year-end
The app is not a tax return โ it's a record-keeping tool. At tax time, you or your accountant uses the exported data to fill in your return. The app integrates with myGov for ATO pre-fill, but it's optional.
Digital vs Paper Records
The ATO accepts both digital and paper records, but digital is strongly recommended. Here's how they compare:
| Factor | Digital | Paper |
|---|---|---|
| Durability | โ Indefinite (with backups) | โ Thermal paper fades, fire/flood risk |
| Organisation | โ Searchable, categorised | โ Easy to lose or misplace |
| Audit readiness | โ Export and email in minutes | โ Must locate and photocopy |
| Cost | Free (myDeductions) or cheap | Minimal (paper logbook) |
| ATO acceptance | โ Fully accepted | โ Fully accepted |
Best practice is a hybrid approach: keep paper receipts in a "tax folder" as they arrive, then photograph them monthly into the myDeductions app or a cloud folder. This gives you double protection.
What Happens in an ATO Audit
If your return is selected for audit, the ATO will send you a written notice asking for specific information. The process typically follows these steps:
- Notification โ You receive a letter or phone call identifying which claims are being reviewed. You have 28 days to respond (extensions are available if you ask).
- Evidence submission โ Provide receipts, logbooks, diaries, bank statements, or any other supporting documents for the claims in question.
- ATO assessment โ The ATO reviews your evidence. If they accept it, the matter is closed. If they don't, they issue a formal position.
- Objection โ If you disagree, you can lodge an objection within 4 years. This escalates to the ATO's Objections team.
- Penalties โ If the claim is disallowed and the ATO believes you were careless, you may face penalties of 25โ75% of the tax shortfall, plus interest.
Common Audit Triggers for Tradies
The ATO uses sophisticated algorithms to flag returns for review. As a tradie, these are the most common triggers:
| Trigger | Why It's Flagged | How to Avoid It |
|---|---|---|
| Tool claims well above industry average | ATO benchmarks by trade โ electricians average ~$800, plumbers ~$1,000 | Keep itemised receipts. Be realistic. |
| Vehicle claims without logbook | Claiming cents-per-km for 5,000 km every year without diary | Keep a logbook or trip diary |
| Large one-off deductions | Suddenly claiming $5,000 in tools one year | Spread large purchases. Keep receipts. |
| Claiming home-to-work travel | This is never deductible but commonly claimed | Only claim site-to-site travel |
| Missing or inconsistent income | ATO cross-checks against employer and bank data | Declare all income accurately |
| Round numbers with no receipts | "$2,000 for tools" with no supporting evidence | Keep receipts or itemised diary notes |
| Consistent refunds while travel claimed | High claims every year without variation | Actual spending varies โ your claims should too |
Record Keeping Checklist for Tradies
| Record Type | Keep For | Format | Notes |
|---|---|---|---|
| Tool receipts under $300 | 5 years | Digital photo | Not strictly required but keep anyway |
| Tool receipts $300+ | 5 years | Digital photo + original | Required for depreciation |

| Site travel diary | 5 years | Notepad or app | Dates, sites, km, purpose |
| PPE receipts | 5 years | Digital photo | Boots, hi-vis, hard hat, gloves |
| Licence and union receipts | 5 years | Digital or paper | White card, EWP, ETU fees |
| Home office records | 5 years | Timesheet or diary | Quote prep, paperwork hours |
| Bank and credit card statements | 5 years | Digital (PDF) | Backs up all purchases |
Summary
Good record keeping for tradies boils down to three habits:
- Photograph every receipt immediately โ before the thermal paper fades or you lose it
- Log your trips as you go โ don't wait until June, you won't remember
- Keep everything for 5 years โ the ATO's clock starts from the day you lodge
The myDeductions app handles all three. It's free, it's official, and it takes 30 seconds per receipt. Every tradie who claims deductions should use it.
