Key Tax Deductions for Lawyers in Australia in 2026

Lawyers in Australia can claim deductions for eligible work-related expenses that help them earn legal income, provided the costs are not reimbursed and are backed by records. Common claims include practising fees, CPD, legal research tools, work travel, home office costs, technology, insurance, accounting fees, and super contributions.

This section breaks down each deduction category, what can usually be claimed, and which expenses lawyers should avoid claiming incorrectly. Keeping these records organised is easier with the support of legal accounting services that understand the specific claims lawyers are entitled to.

Practising Certificate and Professional Membership Fees

Practising certificate renewals and professional memberships are among the most straightforward deductions available to Australian lawyers, as they are mandatory requirements to legally practise in Australia.

• Practising certificate renewal fees issued by state or territory law societies or bar associations
• Membership fees with bodies such as the Law Society of NSW, Law Institute of Victoria, Queensland Law Society, or the Australian Bar Association
• Professional registration fees directly connected to earning legal income
• Receipts or payment records must be kept to support these claims
• Employed lawyers whose employer reimburses these costs cannot claim them as a deduction

Continuing Professional Development Costs

CPD is a compulsory requirement for Australian lawyers under most state and territory law society rules, making these costs both professionally necessary and tax-deductible when directly related to your current legal role.

• CPD course fees, seminar registrations, workshop enrolments, and webinar access costs
• Legal training programs that maintain or improve skills required for your existing role
• Course materials, textbooks, and study resources purchased as part of CPD activities
• Travel to attend CPD events, where the primary purpose is professional development
• CPD undertaken to move into a new career or unrelated legal field does not qualify
• Costs reimbursed by an employer cannot be claimed

Legal Publications and Research Subscriptions

Australian lawyers rely heavily on legal databases and publications for case research, drafting, and court preparation, and these costs are deductible where they are directly connected to legal work.

• Subscriptions to legal databases such as LexisNexis, Westlaw, Bloomberg Law, jade.io, or AustLII premium services
• Legal journals, law reviews, and professional publications used for work-related research
• Case law services, legislation trackers, and regulatory update tools
• Digital legal resources supporting client work, drafting, or court preparation
• Only the work-related portion is claimable if a subscription is shared between personal and professional use

Work-Related Travel Expenses

Travel directly connected to legal duties is deductible, but the ATO draws a clear line between work-related travel and private or commuting expenses, and lawyers must keep records to support their claims.

• Travel between courts such as the Federal Court, Family Court, Supreme Courts, Local Courts, or VCAT hearings
• Travel to client meetings, site inspections, mediations, and arbitrations
• Flights, accommodation, and meals for interstate or regional legal matters or conferences
• Car expenses claimed using either the cents-per-kilometre method or the logbook method as set by the ATO
• Travel to legal conferences and professional events where attendance is work-related
• Regular commuting between home and a fixed workplace is not deductible
• Private travel portions and any reimbursed travel costs cannot be claimed

Home Office Expenses

Lawyers working from home, whether full-time, part-time, or occasionally, may claim a portion of home office running costs, provided claims reflect actual work use and are properly recorded.

• Running costs such as electricity, internet, and phone usage using the ATO’s fixed rate of 70 cents per hour for FY 2025–26
• Office equipment depreciation, including desks, chairs, monitors, and printers used for work
• A four-week representative diary or timesheet is an accepted method to demonstrate work-use hours
• Occupancy costs such as rent or mortgage interest are only claimable where the space is used exclusively for legal work
• Lawyers should be aware that claiming occupancy costs may affect CGT on the property if it is sold
• Costs must reflect actual work use and be supported by written records

Technology and Software Expenses

Legal work is increasingly technology-dependent, and the ATO allows deductions for a wide range of devices, software, and digital tools used in legal practice, with the instant asset write-off offering significant upfront relief for eligible practices.

• Laptops, monitors, printers, and other devices used for legal work
• Legal practice management software, document management tools, and case management platforms
• Cloud storage, cybersecurity tools, e-signature platforms, and online meeting software
• For small legal practices with aggregated turnover under $10 million, assets costing less than $20,000 each can be immediately written off under the instant asset write-off for FY 2025–26, provided the asset is first used or installed ready for use by 30 June 2026
• Assets over $20,000 must be depreciated using the simplified depreciation pool at 15% in the first year and 30% in subsequent years
• Items used for both personal and work purposes can only be claimed for the work-related portion

Phone and Internet Costs

Phone and internet plans used for legal work are partially or fully deductible, but the ATO requires lawyers to apportion costs between work and private use and keep supporting records.

• Work-related calls, client communication, emails, and remote access to legal systems
• Internet usage for legal research, court portals, document filing, and video hearings
• The work-related proportion of a shared phone or internet plan is deductible, not the full amount
• A four-week representative diary showing work versus private use is an ATO-accepted method for calculating the deductible portion
• Costs fully reimbursed by an employer or client cannot be claimed

Stationery, Printing, and Office Supplies

Day-to-day office supplies used in legal practice are fully deductible in the year they are incurred and, while individually small, can add up to a meaningful claim over the financial year.

• Stationery, pens, notebooks, legal pads, and filing supplies used for legal work
• Printing, photocopying, and postage costs related to client correspondence, court documents, and briefs
• Folders, binders, archive boxes, and document storage materials
• All costs must be properly recorded and supported by receipts, even for small purchases
• Office supplies purchased for personal use are not claimable

Professional Indemnity Insurance

Professional indemnity insurance is a mandatory requirement for holding a practising certificate in most Australian states and territories, making it a clear and straightforward deduction for lawyers who bear this cost themselves.

• Professional indemnity insurance premiums paid directly by the lawyer
• Public liability insurance for legal practice owners or sole practitioners
• Particularly relevant for barristers, sole practitioners, legal consultants, and practice owners
• Employed lawyers whose premiums are covered by their employer cannot claim this deduction
• Insurance costs must be directly connected to legal practice activities to qualify

Accounting and Tax Agent Fees

Fees paid to registered tax agents or accountants for managing legal income, deductions, and compliance are deductible, and for lawyers running their own practice, these costs can extend well beyond tax return preparation.

• Tax agent or accountant fees for preparing individual or business tax returns
• Fees for managing work-related deductions, BAS preparation, and GST compliance
• Bookkeeping fees and ongoing accounting support for sole practitioners or legal practice owners
• Fees paid in the year of lodgement are deductible in that financial year
• Keeping these costs documented ensures claims are accurate and audit-ready if the ATO requests supporting records

Superannuation Contributions

Super obligations and personal contributions are deductible under ATO rules, but timing is critical, contributions must be received by the fund, not just paid, before 30 June 2026 to be claimable in FY 2025–26.

• Super paid for employed staff at the mandatory rate of 12% of ordinary time earnings for 2025–26
• Contributions must be received by the complying fund before 30 June 2026, allow at least two weeks for processing
• Sole practitioners and barristers can make personal super contributions and claim a personal deduction
• The concessional contributions cap for 2025–26 is $30,000 per year
• Penalties and interest charged for late super payments are not deductible
• From 1 July 2026, super must be paid at the same time as wages, this will affect cash flow planning for the next financial year

Expenses Lawyers Usually Cannot Claim

Not all work-related costs meet the ATO’s deduction rules, and lawyers should be aware of the common expenses that are frequently claimed incorrectly, as these can attract ATO scrutiny.

• Conventional clothing such as suits, ties, or business attire worn to court, even if purchased specifically for work, these do not qualify as occupation-specific clothing
• Barrister’s robes, wigs, and gowns are deductible as they are occupation-specific and unsuitable for everyday wear, suits are not
• Grooming costs such as haircuts, skincare, or personal presentation expenses
• Regular commuting between home and a fixed workplace
• Client entertainment, meals, or drinks without a clear and documented work purpose
• Expenses reimbursed by an employer or client, only out-of-pocket costs can be claimed
• Fines, penalties, or ATO interest charges incurred from 1 July 2025 onward
