The 183-Day Rule & Permanent Establishment: Business Travel Day Counting Done Right

Tax compliance is a growing challenge for companies navigating international workforces and remote employees. “But just stay below the 183-day limit and you’re good”, we hear you say in excitement. If only it were that simple, as the commonly known tax rule is only one factor businesses must consider when managing tax residency and day counting compliance. The risk of creating a Permanent Establishment (PE) is a serious concern, and failing to manage employee movements properly can lead to unexpected tax liabilities. In this post, we’ll break down the complexities of business travel day counting and what organisations must do to stay compliant.

Corporate Travel Day Counting Challenges

Remote work and international business travel offer flexibility and opportunity for employees and companies. Global Workplace Analytics suggests hybrid working arrangements can save organisations more than $11,000 per employee annually, with 62% of workers saying they feel more productive when working remotely.

However, they also introduce several tax compliance challenges. And what is at the top of that list? Day counting.

On the surface, the 183-day rule seems simple — you stay fewer than 183 days in a country and avoid tax residency. But here’s the catch: the real situation is much more complex.

Countries Use Varying Day Counting Methods

While the 183-day rule is widely adopted, each country often measures those 183 days differently. Some countries use the calendar year, while others use the fiscal year, or a rolling 12-month period

And as we’ve previously explained in our blog post on day counting challenges, how a country defines a ‘present’ day varies. Some countries count any portion of a day spent in their jurisdiction as a full day for tax residency purposes — others don’t.

Activity in the Country Matters

Another layer to consider is what you’re doing in a country, especially for Permanent Establishment. You can create income liability to a country, whether you’re present there for leisure or for work.

For employers, your leisure and business travel may also matter and  employers need to manage ALL days employees spend in a location. If they don’t, then the organisation risks income tax and payroll liabilities.

In addition, what employees do on any given travel or work day can matter, as countries can deem certain activities as creating a PE for the organisation. Companies, then, need to stay on top of the total day count — remember both leisure and work days can matter — as well as the specific work activities performed.

Inaccurate Day Counting: Risks for Business

Your global employees may create significant liability issues for your organisation if you fail to get day counting right. Non-compliance can:

And when tax authorities investigate, it’s not just a financial issue — your company’s reputation is at stake. Compliance investigations can be time-consuming and public, damaging relationships with partners, customers, and employees.

Business Travel Day Counting for Compliance

The good news is that getting day counting right can solve many compliance headaches. Monitoring the number of days your employees spend in foreign tax jurisdictions can significantly reduce the risk of creating PE and ensure compliance with income tax obligations.

Having a clear day counting policy and the right tools in place can make all the difference. Unfortunately, many companies rely on spreadsheets or manual tracking, which introduces room for error. A small mistake in the number of days reported can lead to significant tax penalties.

That’s where day counting technology comes in. 

Automated solutions, like Daysium, simplify the process by providing real-time day count updates based on an employee’s location data. This removes the risk of human error and ensures companies maintain accurate records, regardless of how many employees they have on the move.

Getting Started with Counting Days for Compliance

Here are five essential steps for businesses:

1. Log employee travel days


Real-time, accurate records are crucial for remote and travelling employees. Give your team the tools they need to stay compliant. The challenge with international travel is that employees can forget to log minor trips or make mistakes in manual records. By automating business travel day counting, you reduce the risk of errors and ensure your compliance efforts are as strong as possible.

2. Monitor cumulative days for all employees

It’s not just individual employees to watch out for — track how many employees work in any given jurisdiction. Cumulative presence can trigger PE risks. For example, if multiple employees are working remotely from the same country, even for short periods, their combined presence could lead to the creation of a Permanent Establishment. Monitoring this threshold is critical for avoiding unintended tax consequences.

3. Assess both the 183-day rule and PE thresholds

Both rules matter, and they differ from one jurisdiction to another. Be sure your company understands the specific thresholds where your employees work. Simply staying under the 183-day threshold won’t always be enough to avoid tax residency, and PE can be triggered long before that threshold is reached.

4. Consider specific measurement periods from relevant tax treaties


Double Tax Treaties (DTTs) often have their own rules, which can change over time. Keep these in mind for compliance. For example, some countries have special agreements that adjust how days are counted, or offer exemptions based on the nature of the work being performed. Staying informed on the latest developments in international tax law is crucial for businesses with global footprints.

5. Set clear day-counting policies


Empower employees with clear guidelines and regular updates to ensure day counting stays top of mind. When employees understand the tax risks associated with travel and remote work, they are more likely to stay compliant and avoid creating issues for the company. The State of Business Communication study showed that 72% of business leaders believe effective communication has increased productivity. Regular training, reminders, and easy-to-access resources help reinforce these policies.

Essential Day Counting Concepts to Understand

So to understand the compliance risks associated with day counting, you need to understand the core concepts: the 183-day rule, DTTs, and Permanent Establishment.

What is the 183-day rule?

The 183-day rule is a threshold used by countries to determine when an individual becomes a tax resident. It generally states that if an individual spends more than 183 days in a given country, they become liable to pay income tax there. But this threshold is just one piece of the tax puzzle.

Double Tax Treaty (DTT)

DTTs are bilateral agreements between countries designed to prevent the same income from being taxed twice. They outline specific conditions — based on the OECD Model Tax Convention — that help clarify where an individual or company should pay taxes. These agreements can reduce the risk of double taxation, but they also add layers of complexity when it comes to day counting.

Permanent Establishment (PE)

Creating PE is perhaps the most critical and least understood tax risk companies face. Even if an employee spends fewer than 183 days in a foreign country, certain activities, such as negotiating contracts, managing projects, or having a physical presence like an office or warehouse, can create a taxable business presence in that country. The thresholds and conditions vary from country to country and are often specified in tax treaties.

Current Trend of Cross-border Work

With remote work and cross-border employment on the rise, the risks of triggering PE are higher than ever. Many employees are now choosing to live in different countries while working for employers based elsewhere. This trend can create significant tax challenges for businesses, as governments tighten their regulations on cross-border work.

Business Travel Trends

The key is staying proactive. By regularly reviewing day counts, assessing potential risks, and using technology to support your efforts, companies can manage this trend effectively.

Business Travel Trends in 2024: Why Day Count Compliance Matters More Than Ever

Global business travel has experienced a seismic shift post-pandemic. From having all travel ground to a halt to the rise of hybrid work models, the nature of corporate travel has evolved. As companies now begin to redefine their travel policies, the implications of international travel on corporate tax compliance are growing in significance. Counting employee travel days to avoid unintentional tax residency and reporting liabilities is of strategic importance.

This post explores the current and future business travel trends and how they intersect with the importance of day counting for tax residency compliance. We’d invite business leaders and employees who travel frequently to read until the end for a chance to be part of transforming business travel reporting with Daysium.

The Current State of Short-term Business Travel

In 2020, global business travel came to a standstill due to the Covid-19 pandemic. Even though travel has slowly recovered, it looks different today.

The most notable stats tell the story:

Business travel trends

These changing dynamics are essential for corporations to consider, especially as employees travel across borders and into new tax jurisdictions.

The Role of Hybrid and Remote Work in Business Travel

The big shift after the pandemic has been in our workplace. A central office to gather all employees together every day is no longer a given for companies, big or small. While fully remote work has diminished since the pandemic, hybrid models have taken root. For instance, 26% of employees in the UK worked with a hybrid model as of June 2024.(5) This shift has broad implications—not only are employees splitting their time between home and the office, but they might also be travelling internationally to do so.

Business travel is no longer confined to meetings and conferences. Now, employees may be crossing borders to get to their office every few days of the week. These arrangements raise concerns for companies about payroll reporting obligations and tax residency compliance. Employees who regularly commute from one country to another—for work or business—may unintentionally trigger tax obligations that require day counting to maintain compliance.

The Rise of Digital Nomadism

The improvements in technology combined with the shifting company policies of allowing more hybrid ways to work have led to another shift: an increase in digital nomadism. The trend enables employees to work from anywhere in the world. While this flexibility is attractive to employees, it can create significant tax compliance challenges for employers. Employees who live in one country but work in another could unknowingly create payroll compliance and even tax residency implications for the company, and themselves.

Take, for example, the UK and how its tax authority, HMRC, treats non-resident directors (NRDs). UK companies with NRDs who spend time working in the UK have to operate payroll reporting and withholding duties — whether or not they pay the director. NRDs who perform their work fully remotely abroad may even risk creating issues with the company’s establishment. The UK entity could create a permanent establishment for corporate tax in the location where the NRD lives.

For companies, this requires a proactive approach to tracking day counts. Employees’ ability to lead a digital nomad lifestyle through flexible work arrangements could mean they travel more for work and leisure. This blending of personal and professional travel makes it even more critical for businesses to stay aware of how many days their employees spend in various countries.

Trends Shaping the Future of Business Travel

As companies adjust to this evolving landscape, several trends are driving the future of business travel. Let’s explore these key trends:

Compliance Challenges in Cross-Border Travel

In a globally mobile workforce, cross-border travel poses significant compliance challenges for businesses. Governments worldwide are tightening their tax rules, and failure to comply with tax residency regulations can have severe financial repercussions. Employees who frequently travel to different countries—for work or personal reasons—could easily trigger payroll and tax liabilities in multiple jurisdictions.

Companies need to ensure they count business travel days and check employee residency. International employees need to be managed to ensure compliance with all local tax and employment laws.

The challenge is not only for employers to maintain a clear and accurate record. Considering the impact of digital nomadism and hybrid work, educating employees in their own active role in day counting is vital for compliance. Employees may create unfortunate income tax obligations for themselves if they don’t monitor their work and leisure days spent in specific jurisdictions. To read more on the challenges in cross-border travel for work, you can explore our post ‘Case Study: Navigating Tax Residency Challenges with Daysium’. The case study looks at two Irish cases highlighting the need for immaculate records.

Without proper day count records, businesses and individuals might find themselves grappling with unexpected tax bills, penalties, and audits. A transparent and easy-to-maintain system for day counting can solve many compliance headaches.

Technology as a Solution for Compliance and Efficiency

Technology is playing an increasingly significant role in simplifying corporate travel management. AI and analytics tools are not just improving how businesses book and plan travel—they’re also critical for ensuring tax compliance. Tools that can log travel patterns, optimise itineraries, and integrate with payroll systems are essential in today’s business environment.

At Daysium, we are at the forefront of transforming day counting for tax compliance. Our platform helps individuals effortlessly manage their day counting with an automated logging system. Day counts are tailored based on individual needs, ensuring compliance with relevant legislation. Using Daysium means you’re not just creating an accurate count of days.

The Importance of Day Counting for Future Business Travel

Business travel is not going to disappear, but how, when and for how long we travel for work is transforming. As companies adjust to the hybrid work model and increasingly international workforce, day counting for tax residency compliance increases in importance. Maintaining robust records is a strategic advantage for companies and globally mobile individuals.
