However, at a certain point this activity may create a tax presence.
A tax presence means that the local tax authorities consider your business as local enough to tax you — even if you have no legal entity, branch, or registration. In tax treaties this is called a permanent estabishment, but the concept is broader.
If your activities create a tax presence, this can trigger obligations such as:
corporate income tax on locally attributable profits
local bookkeeping and reporting requirements
registration with tax authorities
penalties or retroactive tax assessments if risks are missed
The difficulty is that tax presence is not always obvious.
Many companies assume that “no company” automatically means “no tax”, which is not always correct.
Tax presence risks often arise when a company:
has employees or directors working from another country
uses local sales agents or representatives
carries out long-term projects or on-site activities
operates warehouses or fixed facilities
manages local operations from a home office
Whether these activities create a tax presence depends on how authorities apply these tax rules in practice.
Tax presence questions in Ireland are handled within a centralised system that combines detailed administrative guidance with a growing body of case law.
Audits, assessments and treaty interpretation are carried out by the Irish Revenue Commissioners, who publish extensive manuals on permanent establishment and international tax concepts (link).
Disputes are first heard by the Tax Appeals Commission and can ultimately be appealed to the Irish High Court and Supreme Court, whose judgments shape how permanent establishment concepts are applied in practice (link).
Irish practice is generally regarded as technically robust and OECD-aligned, but increasingly attentive to substance and people-based activity.
Ireland’s tax treaties largely follow the OECD model, and Irish Revenue places significant weight on the OECD Commentary when interpreting permanent establishment concepts.
A central element in Irish analysis is whether activities carried out in Ireland constitute a fixed place of business or are performed through a dependent agent who plays a meaningful role in the enterprise’s business.
Remote work and home office arrangements have become more prominent in Irish tax presence assessments, particularly for foreign companies employing staff resident in Ireland.
Irish Revenue guidance indicates that a home office may constitute a permanent establishment where it is used on a continuous basis for the employer’s business and is effectively at the disposal of the employer. Where home working is undertaken purely for the employee’s convenience and without employer control, the risk is generally lower (link).
During the COVID period, Irish Revenue confirmed that temporary home working arrangements driven by public health measures would not normally create a permanent establishment. However, this administrative tolerance does not automatically extend to permanent remote work arrangements (link).
Ireland has traditionally taken a relatively conservative approach to dependent agent permanent establishments, but scrutiny increases where Irish-based personnel are closely involved in revenue-generating activities.
Irish Revenue guidance and professional commentary emphasise that a dependent agent permanent establishment may arise where Irish-based representatives habitually negotiate or play a principal role in the conclusion of contracts on behalf of a foreign enterprise, even if formal signature occurs outside Ireland (link).
Activities described as marketing or support are therefore examined closely where they are functionally integrated into the sales or customer acquisition process.
In addition to treaty-based permanent establishment analysis, Irish domestic law considers whether a foreign company is carrying on a trade in Ireland. This concept can trigger filing and compliance obligations even where treaty protection ultimately limits tax exposure (link).
As a result, foreign companies may face compliance requirements in Ireland even in situations where no permanent establishment is ultimately confirmed.
Scrutiny by Irish Revenue typically increases where employees are permanently based in Ireland, where Irish-based staff perform core operational or commercial functions, where home offices are used as a stable operating base, or where sales or customer management activity is carried out locally.
Irish audits tend to focus on factual substance and alignment between operational reality and contractual arrangements.
If tax presence is established, Ireland may assess corporation tax on profits attributable to Irish activities, supported by profit attribution and documentation requirements. Filing obligations may arise even where treaty relief is ultimately claimed.
Retroactive assessments are possible, particularly where activities have expanded gradually without reassessment of the tax position.
In Ireland, incorporation often becomes the cleaner option once employees are permanently based in Ireland, when sales or operational decision-making functions are exercised locally, or when ongoing compliance obligations make operating without a formal entity inefficient. At that stage, incorporation typically provides greater certainty and simplifies both tax and operational compliance.
Across tax systems, the assessment of tax presence typically follows a consistent set of underlying principles:
Substance over legal form
Actual business activities and economic reality carry more weight than contractual labels or formal structures.
People and decision-making
Where key individuals work, negotiate, manage operations or make decisions is often decisive.
Continuity and regularity
Ongoing or recurring activities are treated differently from occasional or incidental involvement.
Economic value creation
Where value is created, managed or controlled is a central factor in tax attribution.
These principles explain why the absence of a legal entity does not automatically eliminate tax exposure.
Tax presence risk is most commonly associated with the following types of activities:
Employees or directors working structurally from another jurisdiction
Sales personnel or agents with decision-making authority
Long-term or recurring on-site projects
Fixed places of business such as offices, warehouses or workshops
Home offices used as a regular base for business operations
The decisive factor is rarely a single activity, but rather the combination, duration and functional role of these activities.
Certain activities are widely regarded as preparatory or auxiliary and typically do not, on their own, create tax presence:
Occasional business travel
Pure marketing or promotional activities
Independent agents acting in the ordinary course of their business
Short-term presence without operational continuity
Supporting functions without decision-making authority
Risk may still arise when these activities evolve or are combined with more substantive functions.
