Tax Return Canberra (ACT) FY2025-26
Canberra workers earn the highest median wages in Australia, but the federal government, defence and public service jobs that fuel that prosperity also create complex deduction patterns. This guide covers every FY2025-26 rule for ACT taxpayers from APS staff to private sector contractors.
The Australian Capital Territory has roughly 470,000 residents, almost all in Greater Canberra. Median weekly earnings hit about 1,250 dollars in 2024 — the highest in the country — which means most ACT workers sit firmly in the 30 per cent FY2025-26 bracket and a large share enter the 37 per cent zone above 135,000 dollars. Stage 3 reforms reduced the top-tier entry from 180,000 to 190,000 dollars, delivering meaningful relief for senior public servants and ministerial advisers. Every dollar of legitimate deductions translates into 30 to 37 cents of tax saved.
Canberra's economy is dominated by federal government, defence and public administration, with smaller clusters in tertiary education at ANU and University of Canberra, embassies, professional services and tech contractors supporting Department of Defence and Home Affairs. APS staff routinely qualify for deductions including security clearance fees (NV1, NV2, PV), Microsoft and AWS certifications, professional memberships such as IPAA, conference fees, and a portion of home office costs for hybrid arrangements. Defence personnel and consultants can typically claim uniform laundry, professional development and union or association fees.
Unlike other states, the ACT is phasing out residential stamp duty in favour of broader-based general rates. New homebuyers in Canberra still pay stamp duty on a sliding scale, but reforms have steadily lowered the burden over the past decade. The territory has no separate land tax for owner-occupiers, though investment properties attract general rates plus a land tax surcharge. None of these affect your federal income tax return directly, but they shape how Canberra investors structure rental properties and how home buyers plan their finances.

Frequently asked questions
Does the ACT have a separate territory income tax?
No. The ACT has no territory-level income tax. All personal income tax in Canberra is collected by the federal ATO under the same Stage 3 brackets that apply nationwide. Public servants, defence personnel and private sector workers all lodge one annual return through myTax or a registered tax agent, and the same federal offsets, Medicare Levy and HECS rules apply regardless of which department or agency employs you.
What can APS public servants claim as deductions?
Australian Public Service staff can typically claim work-related self-education costs (Master of Public Policy, MBA, technical certifications), professional association fees such as IPAA or AICD, union dues, security clearance fees if paid personally, conference and seminar costs, work-related travel between offices, and home office expenses for approved hybrid arrangements. Books, journals and ABC subscriptions used for policy work can also qualify. Keep receipts and apportion any item used partly privately.
How do defence personnel handle uniform and equipment claims?
Australian Defence Force members can claim laundry costs for compulsory uniforms (using either ATO fixed rates or actual costs with receipts), purchase and repair of compulsory items not provided by the employer, fitness equipment if combat fitness is part of the role and the equipment is used solely for that purpose, and travel between bases. Mess fees, regimental subscriptions and self-funded training relating to current rank or specialisation are usually deductible. Keep a logbook for any vehicle claims.
Why is Canberra called the highest-income jurisdiction?
Canberra has Australia's highest median full-time earnings — roughly 1,250 dollars per week as of 2024 — driven by the concentration of federal government, defence and senior public service roles. This pushes a large proportion of workers into the 37 per cent bracket above 135,000 dollars and an unusually high share into the top 45 per cent bracket above 190,000 dollars. As a result, deductions, salary packaging and superannuation contributions deliver outsized tax savings compared with the national average.
Can I claim a home office now that the APS supports hybrid work?
Yes. ACT public servants and federal contractors with formal hybrid arrangements can claim work-from-home deductions using the FY2025-26 fixed rate of 70 cents per hour, covering electricity, internet, phone and stationery. The actual cost method allows itemised claims with full receipts and apportionment. You cannot claim occupancy costs (rent, mortgage interest, rates) unless your home is your principal place of business — typically not the case for APS hybrid roles.
