The short answer for teachers
For classroom teachers on a single school PAYG contract — myTax handles it well if you're disciplined about union fees, classroom supplies, and self-education. Casual relief teachers (CRT), tutors with ABN side income, principals/HoDs with allowances, or anyone with a HECS-HELP balance plus career-change study start needing Agent help.
This guide covers the 5 teacher-specific factors that push you past myTax.
What makes teacher returns complex
1. Casual relief teaching (CRT) across multiple schools
If you do CRT across 3+ schools or change schools mid-year:
- Each school is its own PAYG summary — easy to claim tax-free threshold on more than one (year-end debt)
- Travel between schools same day = deductible (if continuing employment, not new job application)
- Home-to-first-school = NOT deductible (commuting)
- Logbook or cents-per-km up to 5,000 km
CRTs frequently misclassify school-to-school travel and the tax-free threshold gets duplicated.
2. Self-education + further qualifications
Teachers commonly do further study:
- Masters in Education / Special Ed / Educational Leadership
- VIT / TQI registration upgrades + mandatory PD hours
- Subject-area qualifications (e.g., teaching out-of-field permit upgrades)
- Postgraduate certificates in literacy / numeracy intervention
Deductible if directly related to current teaching role (improves income-earning skills). Career-change study (e.g., teaching qualification while still in a previous career) is NOT deductible. Borderline cases (e.g., principal aspirant study) need careful framing.
3. Classroom supplies + home office
Teachers often buy supplies the school doesn't reimburse:
- Books, stationery, classroom decoration, reward stickers
- Subscriptions (Twinkl, Teachers Pay Teachers, Reading Eggs)
- Laptop, iPad, printer for marking and planning
- Home office costs (WFH fixed rate 70¢/hour for marking + planning time)
Need to apportion personal vs work use. The ATO (ATO guidelines) has flagged teacher deductions in recent target audits.
4. Tutoring side income
If you tutor privately (ABN or as a sole trader):
- Triggers Business and Professional Items schedule (myTax doesn't pre-fill)
- GST registration if turnover > $75k (rare for tutors)
- Apportion home use for tutoring vs personal
- Equipment depreciation if you buy tutoring-specific resources
5. Allowances and leave entitlements
- First-Aid allowance, head-of-department allowance, swimming/sports duty allowance — these are assessable income
- Camp / excursion allowances often have a non-taxable portion if reimbursing meals
- Long-service leave payout when leaving a role — taxed differently from regular leave
- Sick leave cash-out (some states) — taxable
Easy to miss the categorisation; Agent reconciles against the PAYG summary.
Decision matrix — teachers
| Situation | DIY in myTax fine? | Agent recommended? |
|---|---|---|
| Single school PAYG, full FY, no extras | ✅ Yes | 🟡 One-off check |
| Single school + small classroom-supply deductions | ✅ Yes | 🟡 Worth review |
| CRT across 3+ schools | ❌ Tax-free threshold trap | ✅ Yes |
| Tutoring side income via ABN | ❌ Business schedule | ✅ Strongly recommended |
| Masters / postgraduate study + HECS | 🟡 Doable but tricky | ✅ Yes |
| Principal / HoD with multiple allowances | 🟡 Doable | ✅ Worth it |
| Recent overseas-trained teacher (VIT bridging) | ❌ Residency rules | ✅ Strongly recommended |
3+ "✅" → Tax Agent self-paying via deductions identified.
Teacher-specific deductions an Agent will check
- Union fees (AEU / IEU / NSWTF / QTU etc) — often forgotten
- VIT / TQI / TRBWA registration fees
- Mandatory First-Aid + CPR + Anaphylaxis training renewals
- Classroom supplies (with receipts — ATO has scrutinised this category)
- Stationery, marking pens, sticky notes (small but adds up)
- Self-education (course fees, textbooks, internet apportionment, travel to face-to-face classes)
- Working with Children Check renewal
- Educational subscriptions (Twinkl, TPT, journals)
- Home office (WFH fixed rate or actual method) for planning + marking
- Phone work-use % (parent communication, student check-ins)
A Registered Tax Agent ensures categorisation and apportionment are defensible if audited. Teacher claims are an ATO focus area in FY2026.
When myTax DIY is genuinely fine for teachers
- Single school PAYG, full FY
- Union fees + 1-2 small deduction categories
- No CRT or only 1-2 schools
- No tutoring / ABN side income
- No major self-education or career-change study
- Comfortable filling out work-related deductions schedule
If 6 of 6 apply, DIY in myTax takes 45 min.
