The shift to distributed teams after 2020 created a tax exposure that most international employers still haven’t fully priced into their hiring decisions. The problem is permanent establishment remote workers generating in a foreign jurisdiction where your company has no registered presence, no office lease, and no intention of doing business. Founders who want to understand the broader choice between incorporating locally, using an EOR, or hiring contractors should read the guide on EOR vs local entity vs contractor, which covers PE risk as part of the compliance analysis.
A single account executive working from their apartment in Singapore or Dubai can, under the right (or wrong) set of circumstances, create a taxable corporate presence that survives long after that employee leaves. I have seen this happen to three different SaaS companies in the past two years, each time with a sales hire they assumed carried zero tax footprint.
The OECD’s November 2025 update to the Model Tax Convention introduced the clearest international framework yet for assessing permanent establishment remote workers risk, built around a two-part test: a 50% working time safe harbor and a commercial reason requirement. But the OECD framework is a floor, not a ceiling. Singapore, Hong Kong, and the UAE each apply their own statutory definitions, thresholds, and enforcement priorities that can diverge materially from what the model convention says.
If you’re hiring into any of these three jurisdictions, the OECD guidance tells you the general shape of the risk. The local rules tell you whether you’re actually exposed.
What is permanent establishment and why remote work changed the rules
A permanent establishment (PE) is a fixed place of business through which an enterprise carries on its activities, wholly or in part. “Fixed” requires some degree of permanence: tax authorities in most jurisdictions treat continuous use of a location for at least six months as crossing that threshold. Once a PE is established, the host country can tax the profits attributable to it at its domestic corporate rate. That liability is separate from, and in addition to, whatever tax your company pays at home.
Before 2025, the treatment of home offices was inconsistent. Some tax authorities held that a foreign employee working from home did not constitute a PE because the employer had no formal control over the space. Others took the opposite view, particularly where the employer paid rent or covered home office expenses. Employers who built remote teams between 2021 and 2024 often did so without formal PE analysis, exposing themselves to retroactive audit risk on multiple years of corporate tax.
The OECD’s November 2025 update addressed this directly. The new guidance introduces two sequential thresholds: the 50% working time test is applied first, and the commercial reason test applies only if that first threshold is met or exceeded.
First, if an employee works remotely for less than 50% of their total working time over any rolling twelve-month period, the home office does not create a PE. Second, even if the 50% threshold is exceeded, PE is only established if the employee’s presence in the host country has a genuine commercial reason connected to the employer’s business activities. Personal lifestyle preferences, cost-of-living advantages, or employee retention are explicitly excluded as qualifying commercial reasons.
The framework applies across the 140-plus countries that have adopted the OECD Model Tax Convention. But Singapore, Hong Kong, and the UAE each incorporate these principles through their own domestic legislation and bilateral tax treaties, with meaningful differences in how they define dependent agents, assess commercial substance, and calculate taxable profits.
Understanding the permanent establishment remote workers framework: Singapore, Hong Kong, and UAE
Singapore: IRAS position and the dependent agent threshold
Singapore defines PE through its domestic Income Tax Act and through its bilateral tax treaties, which follow the OECD model with modifications. Under the ITA, a foreign company is treated as having a taxable presence in Singapore if it carries on business through a fixed place of business or through a dependent agent with authority to conclude contracts on its behalf.
The IRAS e-Tax Guide on PE sets out the two primary triggers. The fixed place test looks at whether the employer controls or has access to a specific location in Singapore where business activities are conducted. The dependent agent test looks at whether an employee or contractor habitually exercises authority to conclude contracts binding on the foreign company, or plays the principal role leading to the conclusion of contracts that are routinely concluded without material modification.
A US SaaS company hiring a Singapore-based account executive who signs subscription agreements on behalf of the parent company presents a textbook dependent agent PE. This is also one reason why the contractor vs employee classification decision matters beyond labor law: a contractor who habitually concludes contracts on behalf of your company creates the same dependent agent PE risk as an employee in the same role.
This is the pattern I encounter most often in practice: the employer focuses on the home office question while the real exposure sits in the contract authority the employee exercises daily. The employee’s home office is secondary; the contracting authority is the operative fact. If the same employee handles only pre-sales qualification and routes all contracts to a US-based sales director for signature, the dependent agent risk drops materially.
Singapore also applies a service PE rule under its tax treaties: if a foreign enterprise provides services in Singapore for more than 183 days in any twelve-month period, through the same or connected projects, a service PE is established. This catches extended consulting deployments that don’t involve a fixed office but involve sustained physical presence.
For a Singapore-based remote worker hired as an employee (not a contractor), the employer’s PE exposure depends on: whether the employee has contract-closing authority, whether the employer subsidizes or mandates the home office, and whether the 50% threshold under the November 2025 OECD framework applies under Singapore’s relevant tax treaty with the employer’s home country. If the foreign employer decides to resolve PE risk by incorporating a Singapore Pte Ltd as a local entity, that entity becomes the legal employer and eliminates the foreign PE exposure, but introduces local compliance obligations. Singapore has concluded over 90 tax treaties, most of which incorporate OECD model language.
Hong Kong: IRD operations test and profits tax attribution
Hong Kong’s profits tax operates on a strict territorial principle: only profits arising in or derived from Hong Kong are taxable. The IRD sets out its approach to PE in Departmental Interpretation and Practice Notes No. 21 (DIPN 21). The standard profits tax rate is 16.5%, with a two-tier system applying 8.25% to the first HK$2 million of assessable profits and 16.5% on the remainder.
For a foreign company with a Hong Kong-based remote employee, the question is whether the employee’s activities generate profits that are sourced in Hong Kong. The IRD applies the “operations test”: it looks at where the profit-generating activities are performed, not just where contracts are signed or invoices are issued. A UK consultancy with a Hong Kong-based project manager who develops deliverables, manages client relationships, and presents findings to Hong Kong clients from a home office in Kowloon is generating profits in Hong Kong, regardless of whether the consulting contract is formally governed by English law and invoiced from London.
The dependent agent PE in Hong Kong requires that a person habitually exercise authority to conclude contracts in the name of the foreign enterprise, or maintain a stock of goods from which they regularly fill orders. A home office used for client meetings and contract negotiation carries more PE risk under this test than one used exclusively for internal coordination.
DIPN 21 does not provide a specific working-time safe harbor equivalent to the November 2025 OECD guidance, since Hong Kong’s tax treaties vary in their incorporation of OECD model provisions. Employers should review the specific treaty between Hong Kong and the employer’s home country, and not assume the 50% threshold applies automatically.
UAE: Federal CT Law Article 14 and service PE risk
The UAE introduced federal corporate tax under Federal Decree-Law No. 47 of 2022, effective for financial years starting on or after June 1, 2023. Article 14 of that law defines PE for non-resident persons, covering fixed place PE, dependent agent PE, and service PE. The FTA’s corporate tax guidance elaborates on each trigger.
The UAE CT rate is 0% on taxable income up to AED 375,000 and 9% on the excess above that threshold (a marginal rate, not a flat rate on total profits). A foreign company with a UAE PE is taxable at these rates on profits attributable to that PE.
For a European manufacturer with a Dubai-based sales agent who habitually concludes contracts, Article 14 creates a dependent agent PE. For a technology company with a Dubai-based remote employee providing software support to UAE clients, the service PE threshold is 183 days in any twelve-month period, consistent with most UAE tax treaties.
One complication specific to the UAE: Free Zone entities. If a non-Free Zone foreign company’s Dubai-based employee operates from a Free Zone co-working space or office, that does not automatically bring the PE within a Qualifying Free Zone Person (QFZP) regime. A PE of a non-QFZP entity operating in a Free Zone is taxable at standard UAE CT rates on its attributable profits. The QFZP 0% rate applies to qualifying income of entities that themselves qualify as QFZPs, not to PEs of foreign companies that happen to be located in a Free Zone.
The 50% working time safe harbor for permanent establishment remote workers in practice
Under the November 2025 OECD framework, the 50% threshold is calculated as remote work days in the host country divided by total working days over a rolling twelve-month period. If the result is below 50%, the home office does not create a PE, full stop.
What counts as “remote work” for this calculation is work performed from the employee’s residence in the foreign country. Travel days, days spent at the employer’s registered offices, and temporary assignments to client sites in third countries are excluded from the numerator. Short-term pandemic-era remote work arrangements were explicitly carved out; the framework targets sustained arrangements of six or more months.
If remote work falls below 50% of the employee’s working time, no PE arises regardless of any other factor. Only when remote work reaches or exceeds 50% does the commercial reason test then apply as the second and final step.
If the employee works from Singapore 60% of the time because they prefer Singapore’s lifestyle and cost structure, and the employer has no business relationship with Singapore clients or suppliers that the employee facilitates, no commercial PE arises. If the same employee works from Singapore 60% of the time because they manage the employer’s Singapore distribution relationships, attend local supplier negotiations, and represent the employer in regional market development, the commercial reason test is likely satisfied and PE analysis proceeds to the power of disposal question.
Employers should calculate and document this ratio quarterly for every remote worker in a foreign jurisdiction, not just those approaching the threshold. If an employee is trending toward 50%, the documentation of commercial reasons (or their absence) needs to be contemporaneous, not reconstructed during an audit.
Power of disposal: the home office control test
For a home office to constitute a fixed place of business, the employer must have what the OECD framework calls “power of disposal” over the location. This means effective control over the use of the space, not merely a formal or theoretical right of access.
If an employee independently rented or purchased their home before joining the employer, and the employer does not pay rent, subsidize utilities, or formally designate the home as an office, the employer has no power of disposal. The employee can refuse access, terminate the arrangement, or move without the employer’s consent. Under these conditions, no fixed-place PE arises from the home office, regardless of how many hours the employee works there.
The analysis flips when the employer finances the workspace. If the employer pays rent for the employee’s apartment or provides a dedicated home office budget as a contractual entitlement, control is presumed. Employers who provide home office allowances should review whether those allowances create or reinforce a power of disposal argument.
| PE risk scenario | Employer pays rent | Employer mandates home office | Employee controls access | Power of disposal | PE risk level |
|---|---|---|---|---|---|
| Employee chose home office independently, no employer subsidy | No | No | Yes (employee can relocate) | Absent | Low |
| Employer provides monthly home office allowance, home office in employment contract | No (cash allowance) | Yes (contractual requirement) | Partial | Present | High |
| Employer pays rent directly for employee’s apartment | Yes | Yes | No (employer has lease rights) | Present | High |
| Employee works from employer-designated co-working space | No | Yes (location specified) | No | Present for co-working space | Medium (location is PE, not home) |
| Employee free to work from home, office, or co-working at their discretion | No | No | Yes | Absent | Low |
The practical implication for employment contracts is direct: avoid language that designates the employee’s home as their required place of work. Contracts should state that the employee may perform work from the employer’s offices, co-working facilities, or another location of the employee’s choosing, subject to the employer’s right to direct where work is performed. That framing preserves flexibility and removes the mandatory home office element that regulators use to infer power of disposal.

Structuring employment contracts to minimize permanent establishment remote workers risk
The contract is your primary compliance tool, and in my experience advising founders across Singapore, Hong Kong, and Dubai, it is the single document most often drafted without PE implications in mind. These provisions reduce PE exposure without limiting operational flexibility.
Work location should be defined as flexible, with the employee authorized to work from the employer’s offices, co-working facilities, client sites, or another location of their choosing. Avoid any clause that designates the home as the primary or required work location.
The contract should not include a contractual obligation to maintain a home office. If the employee’s home is listed as their address for administrative purposes, add language clarifying that this is an administrative designation only, not a required place of business.
Document the percentage of time worked remotely from the foreign jurisdiction on a rolling twelve-month basis. If the employee approaches the 50% threshold, document in writing whether the arrangement has a commercial reason (client relationship management, market development) or a personal reason (employee preference, cost of living). That contemporaneous record is your defense in an audit.
Using an Employer of Record (EOR) in the host country shifts the legal employer relationship to a local entity. This can reduce the foreign employer’s direct fixed-place PE exposure, since the local EOR entity is the contracting party, not the foreign company. However, EOR arrangements do not eliminate dependent agent PE risk if the employee still habitually concludes contracts binding on the foreign company. The EOR model addresses the employment law and payroll obligation; it does not eliminate PE risk if the facts support a dependent agent analysis. Verify with a local tax adviser that any EOR agreement addresses PE responsibility explicitly and allocates that liability clearly between the parties.
FAQ
Does hiring a remote employee in another country automatically create permanent establishment for my company?
Not automatically. PE risk requires a fixed place of business in the host country or an agent concluding contracts on your behalf there.
What is the 50% working time threshold and how is it calculated over a twelve-month period?
The threshold is calculated as the number of days the employee works remotely from the host country divided by total working days over a rolling twelve-month period. If that ratio stays below 50%, the home office does not trigger PE under the OECD framework. Travel days and time spent at the employer’s offices elsewhere are excluded from the remote work numerator. Exceeding 50% requires further analysis of commercial reasons; it does not create PE automatically.
If my company does not pay for or provide the employee’s home office, can it still create permanent establishment?
It can, but the risk is materially lower. Power of disposal over the home office is the central question for fixed-place PE. If the employee independently acquired their home, controls access, and can relocate without employer consent, the employer has no power of disposal and the home office does not constitute a fixed place of business. The dependent agent PE risk persists regardless: if that employee concludes contracts on the employer’s behalf, PE may still arise from the agency relationship rather than the physical location.
What constitutes a “commercial reason” for an employee’s presence in a foreign country under the new OECD guidance?
A commercial reason exists where the employee’s physical presence in the host country itself facilitates the enterprise’s business: managing local customer relationships, maintaining supplier arrangements, or executing market development activities that require local presence. Employee retention, lower labor costs, and employee lifestyle preferences are explicitly excluded. If the employee could perform identical functions from any location and the employer has no clients, suppliers, or business relationships in the host country, no commercial reason exists.
How should employment contracts be structured to minimize permanent establishment risk when employees work from home abroad?
Contracts should define work location as flexible, with no mandatory designation of the home as a place of business. Avoid home office allowances framed as entitlements tied to a specific location. Retain the employer’s right to direct where work is performed. Include a clause stating that any remote work arrangement is at the employee’s election and subject to the employer’s operational requirements. Pair this with quarterly documentation of remote work days to demonstrate sub-50% compliance.
Is personal PE (consultant home office) the employer’s liability or the individual worker’s liability?
For a foreign consultant performing the majority of their billable work from a home office in another country over an extended period, the personal PE risk attaches to the individual, not the hiring company. The consultant may be treated as having a taxable business presence in that country, requiring local tax registration and filing. The hiring company may face separate withholding obligations depending on the host country’s rules, but the PE liability itself belongs to the consultant. This is a meaningful distinction when structuring contractor arrangements across Singapore, Hong Kong, and the UAE.
