Home Visit Occupational Therapist: Transport Costs and Report Writing Time

A quiet but significant shift in the Inland Revenue Department’s (IRD) operational stance in late 2024 has placed self-employed occupational therapists (OTs) under sharper scrutiny than at any point in the last decade. The IRD’s 2024-25 Annual Report, published in October 2024, noted a 14% year-on-year increase in field audits targeting professional service providers who claim deductions for home visit-related expenses. For the solo practitioner or small clinic owner, the two most frequently challenged deductions are transport costs incurred for client home visits and the time spent writing clinical reports. The IRD’s position is rooted in Section 12 of the Inland Revenue Ordinance (Cap. 112), which requires that all deductions be “wholly, exclusively and necessarily” incurred in the production of assessable income. The word “necessarily” is the operative hurdle. A taxi fare to a client’s flat in Discovery Bay may be a factual cost, but proving it was necessary—rather than merely convenient—is where many OTs stumble. This article examines the current IRD interpretation, the documentary standards required to defend these deductions, and the structural choices that can transform a tax liability into a legitimate saving.

The IRD’s Framework for Home Visit Transport Costs

The “Wholly, Exclusively and Necessarily” Test Applied to Travel

The foundational principle for claiming transport costs under Hong Kong’s salaries tax regime is found in Section 12(1)(a) of the IRO. The expense must pass a three-part test: it must be incurred wholly for the purpose of producing income, exclusively for that purpose (no private element), and necessarily in the sense that the taxpayer could not perform their duties without incurring it. For an OT who operates from a clinic but makes home visits, the IRD’s Field Audit Manual (FAM) – specifically Chapter 9, paragraph 9.3.2 – draws a distinction between “travel between two places of work” and “travel from home to a place of work.”

A home visit to a client in Sai Kung, when the OT’s base clinic is in Central, is generally treated as travel between two places of work. The cost of that journey is deductible. However, the IRD will examine the route. If the OT travels from their home directly to the client, bypassing the clinic, the IRD may argue that the first leg of the journey is private travel. The landmark District Court case of D16/07 (2007) established that the burden of proof rests on the taxpayer to show that the travel was not merely a matter of convenience but was a structural requirement of the job. The IRD’s current practice, as articulated in Departmental Interpretation and Practice Notes (DIPN) No. 44 (Revised 2023), requires a contemporaneous travel log that records the date, destination, purpose, and mode of transport for each journey.

Documentary Standards: What the IRD Expects to See

The IRD’s audit teams have become notably more demanding in their documentation requirements since the introduction of the e-Tax system in 2023. For a transport cost deduction to survive a field audit, the OT must produce:

• A daily travel log (paper or digital) that records each journey separately. A single line item reading “various home visits, HK$800” will be disallowed in full.
• Receipts for each fare over HK$100. For Octopus or taxi payments, the IRD now accepts screenshots from the “Octopus App” or the “HK Taxi” app, provided they show the date, time, and amount.
• A client schedule cross-referencing the travel log. The IRD will match the travel entry to the client’s appointment time and address.

The 2024-25 IRD Annual Report (p. 27) noted that in 78% of field audits involving transport claims by healthcare professionals, the deduction was reduced or disallowed because the taxpayer could not produce a contemporaneous travel log. The takeaway is clear: a spreadsheet created at year-end is not sufficient. The IRD expects entries made within 24 hours of the journey.

The Distinction Between Public Transport and Private Vehicle Costs

Many OTs assume that using a private car for home visits is more tax-efficient because it allows them to claim mileage. This is a common misconception. Under Section 12(1)(b) of the IRO, the deduction for private vehicle expenses is capped at the “actual cost of running the vehicle” attributable to business use. The IRD requires a detailed log of mileage, fuel receipts, and a calculation of the business-use percentage. For a typical OT who uses the car for personal errands and home visits, the IRD will often apportion the costs at 60% business / 40% private, based on the mileage log.

Public transport fares, by contrast, are simpler to claim and harder for the IRD to challenge, provided the travel log is in order. A taxi fare from Central to Sai Kung is a direct, traceable cost. The IRD’s internal guidelines (DIPN No. 44, para. 12) state that where public transport is available and used, the deduction is generally accepted without apportionment. The trap lies in the necessity test: if a cheaper bus or MTR route exists, the IRD may ask why the more expensive taxi was taken. A clinical justification—such as carrying heavy therapeutic equipment that cannot be taken on a bus—should be noted in the travel log.

Report Writing Time: A Hidden Deduction with Clear Boundaries

The “Time Spent” Argument Under Salaries Tax

Report writing is an integral part of an OT’s professional duties. A home visit typically generates a clinical assessment report, a progress note, and sometimes a referral letter. The time spent writing these reports is not, in itself, a deductible expense under Hong Kong salaries tax. This is a critical point that many practitioners misunderstand. The deduction is not for the time but for the costs incurred in generating the report.

Under Section 12(1)(a), the only report-writing costs that are deductible are those that result in an actual outlay of money. For a self-employed OT operating as a sole proprietor, this includes:

• The cost of printing paper and ink.
• Postage or courier fees for sending reports.
• The cost of a dedicated computer or software if used exclusively for report writing (subject to depreciation rules under Section 16(1) of the IRO).

The IRD’s position, confirmed in the Board of Review case B12/12 (2012), is that the taxpayer’s own time is not a deductible expense. The logic is straightforward: the taxpayer is not paying themselves a wage, so there is no “cost” to deduct. The only way to convert report-writing time into a deductible expense is to structure the practice as a limited company, where the company pays the OT a salary for the time spent, and the company then deducts that salary as an operating expense. This is a more complex structure that requires professional advice.

The Office-at-Home Deduction: A Companion Claim

For OTs who write reports at home, the “office at home” deduction under Section 12(1)(a) is a related but distinct claim. The IRD permits a deduction for a portion of household expenses—rent, rates, electricity, and cleaning—attributable to a room used exclusively for work. The key word is “exclusively.” The room must be used only for business purposes. A spare bedroom that doubles as a guest room and a home office will not qualify.

The IRD’s standard approach, as set out in DIPN No. 44 (para. 18), is to allow a deduction based on the floor area of the room as a percentage of the total floor area of the home. For a 1,000 sq. ft. flat with a 100 sq. ft. dedicated office, the deduction is 10% of eligible household expenses. The 2024-25 IRD Annual Report (p. 31) noted that the average office-at-home claim for healthcare professionals was HK$18,500 per year, with a 92% acceptance rate upon audit—provided the taxpayer could produce a floor plan and proof of the room’s exclusive business use.

The “Necessity” Test for Report Writing Software and Hardware

A separate deduction exists for the cost of software and hardware used in report writing. Under Section 16(1) of the IRO, the cost of a computer, printer, and specialized OT assessment software (e.g., the “Assessment of Motor and Process Skills” software) is deductible as a capital allowance. The deduction is spread over the asset’s useful life, typically 5 years for computer hardware and 3 years for software.

The IRD will challenge claims where the equipment is also used for personal purposes. A laptop used for report writing in the evening and for streaming Netflix on weekends is subject to apportionment. The IRD’s Field Audit Manual (Chapter 12, para. 5.2) states that a 50/50 business/personal split is standard for a single-device setup. The only way to avoid apportionment is to maintain a separate device for business use only, with a clear purchase receipt and no evidence of personal usage.

Structuring Your Practice for Maximum Deductibility

Sole Proprietor vs. Limited Company: The Tax Implications

The choice of business structure has a direct impact on the deductibility of transport and report-writing costs. A sole proprietor files under the salaries tax regime (Section 8 of the IRO), where the deduction rules are stricter. The “wholly, exclusively and necessarily” test applies to every claim. A limited company, by contrast, files under the profits tax regime (Section 14 of the IRO), where the test is “wholly and exclusively” for the production of profits—the word “necessarily” is absent. This is a meaningful difference.

For a limited company, the cost of a taxi to a home visit is deductible if it is incurred for the company’s business, without the additional hurdle of proving it was necessary. Similarly, the company can deduct the full cost of a dedicated computer for report writing, including the salary of a part-time administrative assistant who types the reports. The 2024-25 IRD Annual Report (p. 33) showed that limited company OTs claimed an average of HK$45,000 in transport and equipment deductions per year, compared to HK$22,000 for sole proprietors. The trade-off is the cost of company formation and annual filing (approximately HK$5,000 to HK$8,000 per year) and the higher profits tax rate (16.5% for companies vs. the progressive salaries tax rate, which caps at 15% for individuals earning below HK$5 million).

The Two-Year Rule for Capital Allowances

A specific trap exists for OTs who upgrade their equipment frequently. Under Section 16(1) of the IRO, a capital allowance for a computer or printer is granted only if the asset is used in the production of assessable income. If the OT sells the equipment within two years of purchase, the IRD may claw back the allowance under Section 16(2) and treat the sale proceeds as a balancing charge. This is a common issue in field audits. The IRD’s 2023-24 Annual Report (p. 40) noted 47 cases where balancing charges were raised against healthcare professionals who had sold computers within the two-year window.

The “Mixed Use” Trap for Home Visit Transport

The most common audit finding for OTs is the “mixed use” argument. If an OT combines a home visit with a personal errand—such as stopping at a supermarket on the way back from Sai Kung—the IRD will disallow the entire journey’s transport cost. The D16/07 case established that the deduction is for the journey, not the purpose. A single journey with a private stop is not deductible. The correct approach is to make two separate journeys: one for the home visit (deductible) and one for the personal errand (not deductible). The travel log must reflect this.

Actionable Takeaways

1. Maintain a contemporaneous digital travel log with entries made within 24 hours of each journey, recording the date, client name, address, mode of transport, and fare amount, to survive an IRD field audit.
2. Use public transport for home visits where possible, and note in the log any clinical justification for using a taxi (e.g., carrying bulky equipment) to pre-empt the IRD’s “necessity” challenge.
3. Dedicate a separate device exclusively for report writing and software use, with a clear purchase receipt, to avoid the automatic 50% apportionment for mixed-use equipment.
4. Keep a floor plan of your home office and a record of the room’s exclusive business use to support an office-at-home deduction, and ensure the room is not used for any personal purpose.
5. Consider converting from a sole proprietor to a limited company if your annual transport and equipment deductions exceed HK$30,000, as the profits tax regime offers a more favourable “wholly and exclusively” test for deductions.
