Let’s be honest, “permanent establishment” sounds like one of those dry tax terms you’d rather not think about. But if your company has people working from different countries or states (even temporarily), it’s something you really need to understand.

That’s because permanent establishment, or PE for short, can sneak up on businesses and lead to unexpected tax bills, audits, and a lot of avoidable stress.

So what actually counts as a permanent establishment? How do you know if your remote or mobile workforce is putting you at risk? And more importantly, what can you do to stay ahead of it?

Let’s break it down.

First, What Is Permanent Establishment?

Permanent establishment (PE) is a tax rule used by many countries to decide if your business has enough of a presence in their territory to owe them taxes.

That “presence” doesn’t have to be a physical office. It could be:

  • An employee working remotely from abroad
  • A salesperson closing deals in another country
  • A consultant running operations on the ground

If local authorities think you’re “doing business” within their borders (even unintentionally) they may decide you have a permanent establishment and hit you with corporate taxes, fines, or even social security obligations.

The 183-Day Rule & Permanent Establishment: Is There a Firm Threshold You Have to Hit? 

One of the main things tax authorities look at is how much time a business, or its employees, spends operating in that country. This is known as the "day count."

You’ve probably heard of the 183-day rule. It’s a common benchmark used in many tax treaties and laws. But it’s not always as simple as it sounds:

  • 183 days is a key threshold, but not the only one.

    • Many countries use it as a trigger for creating a “service PE” or deciding if an individual becomes a tax resident. But it’s just one piece of the puzzle.

  • Not all PEs follow the same rules.

    • Construction PEs often require a presence of 6 to 12 months (sometimes even just 3, depending on the treaty).

    • Fixed Place PEs aren’t about day count at all, they’re based on having a permanent, regularly used location like an office.

  • Day-counting rules vary.

    • Some countries count every calendar day. Others count only workdays, use fiscal years, or apply a rolling 12-month window. The method can make a big difference.

  • Time isn’t the only factor. A PE can also be triggered if a business has:

    • A fixed office or branch in the country,

    • A dependent agent who can sign contracts on its behalf,

    • Or is carrying out certain kinds of business activities, even for a short time.

Bottom line: PE rules are nuanced, and the 183-day threshold is just the tip of the iceberg. Companies with cross-border operations need to pay close attention to local tax rules to avoid surprises, which can be hard when manually tracked and recorded. 

What Triggers Permanent Establishment?

It doesn’t take much to trigger PE risk. Here are some surprisingly common scenarios:

  • An employee works remotely from Spain for a few months
  • A U.S.-based exec logging in from Canada during a series of trips
  • A sales rep that lives just over the border and regularly meets clients in-person
  • A temporary project becomes a long-term engagement abroad

In all of these cases, the company might suddenly owe taxes in that country, even if they’re not formally registered there.

Why This Matters More Now

In the old days, it was easy to track where business was being done. Now? Not so much.

With hybrid work, relocations, and cross-border hiring, tax authorities are watching more closely. And they’re cracking down.

If your company unknowingly creates a permanent establishment, you could face:

  • Unexpected tax bills
  • Interest and penalties
  • Double taxation (yep, taxed at home and abroad)
  • Reputational risk from noncompliance

FAQs: What You Need to Know About Permanent Establishment (PE)

1. What is permanent establishment (PE) in international tax?

Permanent establishment, often called PE, is when your business has enough of a presence in another country that the local tax authority says, “Hey, you owe us corporate taxes here too.” It doesn’t always mean opening an office; even having employees or agents working abroad can count.

2. What triggers permanent establishment risk?

There are a bunch of ways you can accidentally trigger PE, like employees working from another country, signing contracts while traveling, regularly doing sales or business in a new region, or having someone represent your company abroad. Even just one of these things can create tax obligations in that country.

3. Can remote work create a permanent establishment?

Yes, and this is becoming a big issue as more people work from anywhere. If a remote employee is generating revenue, managing clients, or operating long-term from another country, they could create a taxable presence for your business there.

4. How many days can an employee work in another country without creating PE?

There’s no one-size-fits-all answer. Some countries have specific thresholds (like 183 days per year), but others look at things like job duties or whether revenue is being generated. It’s not just about time, it’s about what the employee is doing while they’re there.

5. Is permanent establishment triggered during a continuous amount of time or is it calculated over a series of trips?

It can be either! Some countries count total days worked in their jurisdiction, even if they’re split across multiple short trips. Others look at continuous stays. The key is tracking both time and activity, because both can add up to PE.

6. What are the consequences of creating a permanent establishment?

In short: unexpected tax bills. But it doesn’t stop there. You could also face: late payment penalties or interest, double taxation (paying in two places), time-consuming audits reputational damage with tax authorities

7. How can businesses avoid triggering permanent establishment?

The best defense is visibility. Know where your people are working, for how long, and what they’re doing. Tools like Monaeo Enterprise help automate location tracking, flag risks early, and keep you compliant, so you’re not relying on spreadsheets or guesswork.

8. What is the difference between permanent establishment and nexus?

Think of it this way: PE applies to international taxes, while nexus is a similar concept used within the U.S. Both mean that your business has created a taxable presence, but in different jurisdictions.

9. Does having a dependent agent in another country cause PE?

It can. If someone is regularly acting on behalf of your company, like closing deals, signing contracts, or even just negotiating, they may be considered a “dependent agent,” which is a common PE trigger.

10. Can using contractors or freelancers abroad create PE?

Possibly. If they’re acting like full-time employees, or regularly representing your business, a tax authority might treat them as a dependent agent, which could trigger PE. It depends on the level of control and the nature of the work.
