What you need to know about the 183-day rule
Introduction
You’ve likely encountered the 183-day rule when dealing with employees working across borders. At first glance, this rule might seem straightforward: if someone works in a foreign country for more than 183 days, certain tax implications kick in. However, as is often the case with international tax rules, things are never this simple.
The 183-day rule is the most well-known rule in tax treaties, that determines which country has the right to tax employment income. There’s a catch though: the application of this rule varies depending on the specific tax treaty, and it’s not the same as the 183-day threshold some countries use in their national laws to determine tax residency. These distinctions can lead to misunderstandings and compliance risks if overlooked.
In this blog, we’ll explore the ins and outs of the 183-day rule for tax treaty purposes, clarify its variations across tax treaties, and discuss its implications for both employees and employers. We’ll also highlight situations where the 183-day rule doesn’t apply and provide practical tips for HR professionals managing cross-border workers.
The Basics
At its core, the 183-day rule is one of the rules that allocates taxing rights to the country where an employee physically works, provided certain conditions are met. These conditions often revolve around the duration of stay and the employer’s place residence.
How the Rule Works
The 183-day rule involves two countries: the employee’s resident state and the working state. Tax treaties typically stipulate that an employee is taxable in the working state only if they are physically present there for more than 183 days during the relevant reference period (e.g., calendar year, tax year, or any 12-month period). The 183-day count is based solely on the employee’s physical presence in the specific working state – days spent in other foreign states do not count toward the threshold.
This means that if an employee works in multiple countries, the 183-day rule is assessed separately for each country. For example, an employee who spends 100 days in Country A and 150 days in Country B within the same tax year would not trigger tax liability in either state under the 183-day rule, assuming no other conditions are met.
Counting the Days
It’s also important to consider how days are counted. Partial days of presence (e.g., arrival or departure days) count toward the 183-day total. Additionally, non-working days like weekends, public holidays, and sick days may be included if they are spent in the working state.
Tax Residency Considerations
While the 183-day rule focuses on employment income taxation, it’s worth noting that some countries also determine tax residency based on days of presence in that specific country. This threshold is often also set at 183 days as well. This does not mean though that an employee automatically becomes a tax resident abroad when the 183-day threshold is exceeded, as tax residency is addressed in tax treaties as well. The tax resident provision in tax treaties typically determines residency based on factors such as permanent home, center of vital interests, or habitual abode. If residency cannot be resolved under these criteria, the tax treaty often defers to the mutual agreement of the tax authorities of the involved states.
The distinction between the 183-day rule and tax residency is crucial for compliance. Just because an individual exceeds 183 days in a working state does not necessarily mean they become a tax resident there, and vice versa. It is possible though that exceeding 183-days of presence in a country triggers a registration obligation in the working state, but this will be based on national legislation and has nothing to do with the tax treaty.
Exceeding the 183-Day Threshold: What’s Next?
When an employee exceeds the 183-day threshold in a foreign country and the 183-day rule was applicable, most likely tax implications will occur. In most cases, the working state gains the right to tax the income related to work performed within its borders. However, there are other consequences to consider.
Tax Liability with Retroactive Effect
One key aspect of exceeding the 183-day rule is that the tax liability generally applies retroactively to the entire period of presence in the working state, not just the days beyond the 183-day threshold. This means that even if an employee has worked for 184 days, the entire 184 days of income earned in the working state could become taxable there.
Employer Obligations
Employers may face additional responsibilities, such as registering for payroll taxes in the working state, withholding taxes from the employee’s salary, and filing tax returns. These administrative requirements can be complex and may vary depending on local regulations.
Employee obligations
Employees may face additional responsibilities as well, such as registering with the local tax authority and/or filing foreign income tax returns.
Avoiding Double Taxation
Tax treaties aim to prevent double taxation, so in case of foreign tax liability (based on the 183-day rule), a deduction for the avoidance of double taxation becomes available in the employee’s resident state. The extent to which a deduction is available, depends on the specific tax treaty as well as local rules on tax relief.
Variations in the 183-Day Rule Across Tax Treaties
Not all 183-day rules are created equal. While the general concept is the same—allocating taxing rights based on physical presence—the specific details often vary depending on the tax treaty. These should always be kept in mind when assessing tax liability of employees.
Reference Periods
The most significant variation lies in how the 183 days are counted. Tax treaties typically define the reference period in one of the following ways:
Calendar Year: The 183 days are calculated from January 1 to December 31, regardless of the local tax year.
Tax Year: The period aligns with the country’s fiscal year, which may differ from the calendar year (the UK tax year for instance).
Any Rolling 12-Month Period: In this case, the 183 days can span across two calendar or fiscal years, if they fall within a 12-month window.
These differences can have significant impact on an employee’s tax liability. For instance, an individual working in a country from September 1 to March 31 might not exceed 183 days in a calendar year but could still surpass the threshold when assessed on a rolling 12-month basis.
Situations Where the 183-Day Rule Doesn’t Apply
Although the 183-day rule is the most well-known provision for determining tax liability of employee income, there are many situations in which the rule either doesn’t apply or is overruled by another provision.
The Economic Employer Rule: If the economic employer is based in the working state, tax liability may arise as from day 1, even if the 183-day threshold hasn’t been exceeded. If the employee works on at the risk and expense of a entity in the host country, the host entity may be viewed as the “economic employer”, regardless of the contents of the employee’s formal employment contract.
Board Members: Income earned by board members is typically taxable in the country where the company is headquartered, regardless of how many days they spend in that country. This is a specific provision found in most tax treaties that overrides the 183-day rule.
Permanent Establishment (PE): If an employee’s activities in a foreign country create a permanent establishment (PE) for their employer, the income related to work performed in that country may become taxable there, regardless of the 183-day rule.
Offshore Work: Employees working offshore, such as in the oil and gas industry, are often subject to special tax rules. These rules can differ significantly from the standard 183-day rule and may impose tax liability even for short periods of work in a country’s territorial waters.
No Applicable Tax Treaty: In situations where no tax treaty exists between the employee’s resident state and the working state, the 183-day rule does not apply. Instead, local tax laws of the working state govern taxation, which may lead to more immediate or comprehensive tax obligations.
Practical Steps
Managing cross-border employees within the framework of the 183-day rule can be challenging, but a proactive approach can mitigate risks and ensure compliance.
Track Employee Presence: Implement systems to monitor employees’ days of physical presence in foreign countries. This can be achieved using time-tracking tools, travel records, or employee self-reporting. Accurate tracking is essential to determine whether the 183-day threshold is at risk of being exceeded.
Understand Tax Treaty Provisions: Familiarize yourself with the specific provisions of the tax treaties between the employee’s resident state and the working state. Pay attention to variations in reference periods, exceptions, and how days are counted.
Consult Tax Experts: Engage tax professionals to evaluate complex scenarios, such as situations involving multiple countries, the economic employer rule, or potential permanent establishment risks. Expert advice can help navigate nuances and avoid costly mistakes.
Communicate with Employees: Educate employees about the potential tax implications of working abroad. Clear communication ensures that employees understand their responsibilities and helps manage expectations.
Plan Assignments Strategically: For assignments close to the 183-day threshold, consider structuring work schedules to minimize the risk of triggering tax liability. This might involve staggering workdays or arranging remote work from the resident state. When the tax rate in the work state is low it could be beneficial to extend the assignment so it exceeds 183 days and as a result a lower tax rate can be secured.
Monitor changes: new tax treaties can be concluded, or existing treaties can be changed, as a result whereof also situations can change. Also changes in local tax laws and case law can have an effect on the calculation of the 183-day rule.
By adopting these practices, the challenges of the 183-day rule can be managed effectively, while supporting employees and safeguarding their organizations from compliance risks.
Summarizing
While the 183-day rule serves as a basic provision for allocating taxing rights, variations in its application and the numerous exceptions make the rule far from straightforward.
By tracking employee presence, understanding treaty details, consulting experts, and educating your workforce, you can minimize compliance risks and ensure a smoother experience for employees working across borders.
When in doubt, seeking tailored advice from tax and mobility professionals can make all the difference.
