What can ADF and Defence Force members claim on tax?
ADF members can claim the same core work-related deductions as any employee, plus several specific to military service, set out in the ATO's ADF members guide: compulsory uniform costs, tools and equipment, some self-education, travel between postings and bases, conferences and training, and certain protective gear. The bigger risk isn't what people forget to claim, it's what they wrongly assume they can: relocation costs, mess tickets, a new driver's licence, and HECS-HELP fees are all private expenses in the ATO's eyes, however service-related they feel. Darwin's large ADF community makes this one of the areas we see the most missed or over-claimed deductions in.
The three golden rules still apply
Nothing about ADF service changes the basic test: you must have spent the money yourself and not been reimbursed, the expense must directly relate to earning your income, and you need a record to prove it. If your unit or Defence pays for something, or reimburses you, it isn't deductible, even if it's genuinely service-related.
What ADF members can generally claim
Travel between postings, bases, or worksites. Travel directly connected to your duties, driving between two workplaces on the same day, or to a location other than your regular base for work purposes, is deductible. Ordinary travel from home to your regular base generally is not, the same rule that applies to any employee's daily commute. You can use either the cents-per-kilometre method (currently 88 cents per kilometre, capped at 5,000 work kilometres per car) or a logbook, and either way you need a record showing dates, purpose, and distance.
Conferences, seminars, and training courses. Fees, travel, accommodation, and meals for attending a genuinely work-related conference or training course are deductible, including overnight stays where the event requires you to travel away from home. If there's a private element to the trip, that portion isn't claimable.
Protective items for the job. Items genuinely needed to protect you while performing outdoor or field duties, such as an issued hat, sunscreen, or sunglasses for sun protection during outdoor work, can be deductible, separate from the general uniform claim.
Field and deployment equipment handling. Where you're required to transport compulsory field or deployment equipment to and from your home because of its size or storage needs, related costs can be deductible.
Professional publications and union or association fees. Subscriptions to service-specific journals and annual (not joining) fees to relevant associations are generally deductible.
What ADF members commonly assume is deductible but isn't
This is where the real money gets lost, not on missed claims, but on claims that feel obviously service-related and simply aren't:
- Posting or relocation costs. Removalist, storage, and transport costs when you're transferred between bases are private expenses, not deductible, even though Defence initiated the move.
- Driver's licence or passport. The cost of obtaining or renewing either is not deductible, even if your role requires you to hold one.
- Weapons and standard-issue equipment. Rifles, ammunition, cleaning kits, and similar items are normally supplied and replaced by the ADF, so they can't be claimed even if you occasionally top these up yourself.
- Mess and function tickets. Tickets to a mess dinner, ball, or similar function are private, even where attendance is effectively expected as part of service life.
- HECS-HELP fees. Course fees paid through HECS-HELP are not deductible, even where the underlying course itself would otherwise qualify as work-related self-education.
- Phone or internet connection and installation. The one-off cost of connecting a phone, mobile, or internet service isn't deductible; ongoing work-related usage costs are a separate matter and may still qualify.
- General sporting activity. Participating in sport isn't deductible unless you're on duty and either representing the ADF officially or required to participate as part of a specific role.
Tools and equipment, uniforms, and self-education
Uniforms. The ATO treats military uniforms as compulsory, so you can claim the cost of buying, repairing, and laundering distinctive items: military shirts with rank markings, dress uniforms, and other compulsory issued or approved wear. What you can't claim is anything non-compulsory or that could pass as everyday clothing, running shoes, plain t-shirts, or standard underwear, even if you happen to wear them on base.
Tools and equipment. If you buy tools or equipment genuinely used for your role, you can claim the cost, including repairs and insurance. Items costing $300 or less can be claimed in full immediately; anything over that is claimed as depreciation over several years.
Self-education. Course fees, textbooks, and related travel can be deductible where the study maintains or improves skills for your current role, and paid outside the HECS-HELP system (see below). Study for a completely different future career isn't deductible, even if Defence encourages it.
Home office running costs. If you genuinely work from home for part of your role, the same working-from-home rules apply as for any other employee, either the fixed rate method or actual costs. See our guide to working-from-home and phone claims for the detail.
Fitness, grooming, and allowances
Grooming, haircuts, gym memberships, and general fitness costs are not deductible for most roles, even though maintaining fitness is a genuine service requirement. The narrow exception is where your specific role demands a fitness standard well above the general ADF standard and strenuous physical activity is an essential, regular part of the job, a Special Forces physical training instructor is the ATO's own example, not a general combat-fitness allowance.
Allowances, such as a uniform or field allowance, need to be declared as income; they don't automatically become a matching deduction. You separately claim whatever you actually spent on a deductible expense and can substantiate, which may be more or less than the allowance itself.
Two things specific to Defence worth knowing
The overseas forces tax offset. If you served in specified overseas localities as part of your Defence duties, you may be entitled to the overseas forces tax offset instead of the standard zone offset, worked out the same way as the Zone A offset. You can only claim one of the two, whichever is higher.
The Medicare levy medical exemption. If you receive full free medical treatment under Defence arrangements, you may qualify for a Medicare levy exemption under the medical category, separate from the foreign-resident and not-entitled-to-Medicare categories most people ask about. See our Medicare levy exemption guide for how the exemption categories work.
What we check before lodging
For ADF clients, we specifically check that uniform, equipment, and travel claims are for genuinely compulsory or work-specific items rather than general fitness, grooming, or private costs like relocation and mess functions, that any allowance declared as income has a properly substantiated matching deduction rather than an assumed one, and that overseas service or medical exemption entitlements haven't been missed. Given how many Darwin returns involve Defence income, this is one of the areas we audit most closely before lodging.
Frequently asked questions
No. Relocation costs, removalists, storage, and transport when transferring between bases, are treated as private expenses, not deductible, even though the ADF initiated the move.
