Office worker tax return checklist for 2026

An office return is rarely one big deduction. It is a stack of small lines: the hours you worked from home, the chair you bought yourself, a professional membership on a card you barely check, the fee you paid your agent last year. Each is easy to skip, and skipped lines are money left with the tax office. Run through the list below before you lodge, so the things you genuinely paid for make it onto your return and the usual wrong claims stay off it.

The three golden rules

Before anything goes on your return, hold each expense against four tests. If a line fails one of them, leave it off.

• You paid for it yourself and were not reimbursed. If your employer covered the cost, or paid you back, it is not your deduction.
• It directly relates to earning your income. There has to be a real connection between the expense and the work you are paid to do, not just a loose link to having a job.
• You have a record. A receipt, invoice or statement that shows what you bought, when and for how much. No record, no claim.
• Part-private means you claim only the work share. A phone, a laptop or an internet connection used for both work and life is claimed at the work-use portion, not the whole bill.

What to gather before you open your return

Pull these together first. Most office deductions come from this list, and having the records in front of you is what turns a rushed estimate into a claim that holds up.

• Your working-from-home hours for the whole year. If you use the fixed-rate method, you need a record of the hours you actually worked at home over the whole year, built up as you went: a roster, timesheet, diary or calendar all qualify, while an estimate or a four-week sample does not. The fixed rate is a cents-per-hour figure the ATO resets each year, so read the current rate off the ATO page before you multiply.
• Your working-from-home running costs, if you use actual cost instead. Energy, phone, internet and stationery bills for the year, ready to apportion to the work share. Note that the fixed rate already bundles those costs, so you choose one method, not both.
• Receipts for equipment you bought yourself. A desk, chair, monitor, laptop or headset for work. Items costing $300 or less come off in full the year you buy them; items over $300 are claimed a little each year as they decline in value. Either way, only the work-use share counts.
• Professional membership and association renewals. The renewal of a membership or union or association fee you need for your current role, such as CPA Australia, CA ANZ, AHRI or an industry body. Keep the renewal notice.
• Self-education tied to your current role. Course fees, materials and travel for study that maintains or improves the skills of the job you do now, or that is likely to lift what you earn in it. Study aimed at breaking into a different role does not qualify.
• The work share of your phone and internet. Worked out from a representative four-week diary, and only claimed here if you are not already covering them through the WFH fixed rate.
• Income protection premiums held outside super. Premiums for a policy you hold in your own name, not one bundled inside your super fund.
• Last year's tax agent fee. What you paid a registered agent to prepare your previous return is deductible on this one.
• Work bags and briefcases. A bag or case you bought to carry work items such as a laptop, files or documents, at the work-use share.
• Overtime meals, only where an award allowance is paid. A meal bought while working overtime is claimable only when your award pays an overtime-meal allowance for it. Read the current reasonable amount off the ATO page rather than assuming a figure.

The chapters break these down further: the two home-office methods are in the working-from-home chapter, the $300 rule and depreciation in the equipment chapter, and study and memberships in the self-education and memberships chapter. Phone, travel and record-keeping sit in the phone, travel and records chapter.

Leave these off

These feel work-related and are not. They are where office returns most often get knocked back.

• The commute. Home to your regular workplace and back is private travel, however long the trip or however early the start.
• Your work wardrobe. Conventional business clothing, a suit, a blouse, black trousers, plain shirts, is not deductible even when a dress code requires it. The clothing rules and the narrow exceptions are set out in the clothing chapter.
• Coffee and lunch during normal hours. Meals and drinks you buy on an ordinary working day are a private cost, not a deduction.
• Rent, mortgage interest, rates and house insurance. These are occupancy costs, and an employee working from home cannot claim them. This is the single most common wrong claim on office returns.
• The qualification that first got you into the field. The study that qualified you to start the job, or that shifts you into a different one, is not deductible.
• HELP and HECS-HELP repayments. Repayments on a study loan are never deductible.

Without the records, the claim will not stand

A claim lives or dies on the evidence sitting behind it. The "$300 without receipts" line is not a free amount to tack on: you must genuinely have spent the money, and the moment your total work-related claims go past $300 you need written evidence for every one of them, not only the part over $300. The record office workers most often come up short on is the whole-year note of home-work hours the fixed rate now demands, so jot those hours down as the year runs instead of piecing them together at tax time. The ATO's free myDeductions tool logs receipts and hours as you incur them.

The bottom line

Run this checklist once before you lodge and the lines that usually slip through, the WFH hours, the chair you bought, the membership renewal, last year's agent fee, land back on your return. Claim the work share of what you paid for and can evidence, keep the commute, the work wardrobe and occupancy costs off, and your bill settles on your real income once the genuine work costs come out.
