Remote working has changed the way many professionals live.

A person is employed by a UK company.
The employment contract is with the UK employer.
The salary is paid in the UK.
The payroll is operated in the UK.
The person still considers themselves UK-based.

Then, for personal or family reasons, they decide to work remotely from Italy, Spain, Portugal, France, Dubai, Switzerland, Thailand or another country.

Perhaps it is only meant to be for a few months.

Perhaps they are helping elderly parents.
Perhaps they want to test life abroad.
Perhaps they are spending more time in their country of origin.
Perhaps they have a holiday home.
Perhaps they simply believe that, because work is now online, location no longer matters.

From a human perspective, this is completely understandable.

From a tax perspective, however, it can be dangerous.

The biggest mistake people make is assuming that, because their employer is in the UK and their salary is paid in the UK, their employment income is automatically taxable only in the UK.

That is not how international tax works.

In most cases, employment income is connected to where the work is physically performed.

So, if you are physically sitting in another country while performing your employment duties, that country may ask a very simple question:

“Why should this income not be taxed here?”

This is where the famous “183-day rule” is often misunderstood.

Many people believe that, provided they spend fewer than 183 days in another country, there is no tax problem.

That is not correct.

The 183-day rule is not a universal tax-free pass.

It is usually part of a double tax treaty analysis, and it only helps if all the relevant treaty conditions are satisfied. Depending on the country, the facts and the employment arrangement, the foreign tax authority may still consider whether the employment duties are performed locally, whether the cost is borne locally, whether there is an economic employer in that country, and whether the individual has created a broader tax residence or reporting issue.

In practical terms, the problem is not only:

“How many days have I spent abroad?”

The better questions are:

“Where am I actually working?”
“Where am I creating value?”
“Where am I making decisions?”
“Where is my family life and centre of interests?”
“Could I become tax resident in the other country?”
“Could my salary, bonus or share awards be taxable there?”
“Could my employer have payroll obligations there?”
“Could social security be due in the wrong country?”
“Could my presence abroad create a problem for the company itself?”

For employees, the risks are often personal and immediate.

You may become tax resident in the foreign country.

Part of your salary may become taxable there.

You may need to file a local tax return.

You may suffer double taxation if the position is not managed correctly.

Your employer may be required to operate payroll withholding in that country.

Your UK PAYE position may need to be reviewed.

Your social security position may need an A1 certificate or certificate of coverage.

Your pension contributions may not be treated as expected.

Your private medical cover, benefits, bonuses or equity awards may have unexpected tax treatment.

If you receive RSUs, share options, carried interest, deferred bonuses or other incentive income, the position can become even more complex because the income may need to be apportioned between countries by reference to workdays, vesting periods or periods of residence.

For directors, founders, partners, consultants and senior executives, the issue is even more serious.

Why?

Because your personal remote-working arrangement may also create a corporate tax problem for the business.

If you are simply answering internal emails from abroad for a short period, the risk may be manageable.

But if you are working from another country and you are negotiating contracts, managing key clients, directing employees, making strategic decisions, approving budgets, controlling operations or acting as the face of the business in that country, the foreign tax authority may argue that the company itself has a taxable presence there.

That is the Permanent Establishment risk.

In plain English, a Permanent Establishment is a corporate tax footprint in another country.

It can mean that the company must register locally, file tax returns locally, allocate profits to that country, deal with transfer pricing, and potentially manage local payroll, VAT or social security obligations.

This is why many employers are becoming more cautious about remote working from abroad.

It is not simply bureaucracy.

It is not because they dislike flexibility.

It is because one employee working from the wrong country, doing the wrong activities, for the wrong length of time, can create tax consequences for both the individual and the employer.

The most dangerous cases are usually the informal ones.

Nobody signs a secondment agreement.

Nobody reviews the double tax treaty.

Nobody checks payroll.

Nobody checks social security.

Nobody checks immigration status.

Nobody reviews the employee’s role.

Nobody checks whether the employee can bind the company.

Nobody asks whether the home abroad has effectively become a business base.

Then, one or two years later, the position becomes difficult to defend.

This is particularly relevant for:

UK employees working remotely from Italy or elsewhere in Europe;

Italian nationals living in the UK who spend extended periods back in Italy;

senior executives working from a second home abroad;

founders managing a UK company while living overseas;

consultants who travel frequently between countries;

employees with bonuses, RSUs, options or carried interest;

UK companies allowing staff to work abroad without a formal policy;

and families who gradually relocate without properly planning the tax consequences.

Remote working abroad can be perfectly legitimate.

But it needs to be structured.

Before working remotely from another country, the individual should ideally check the following points:

Where will I be physically working from?

How many days will I spend there in the tax year?

Will I remain UK tax resident under the Statutory Residence Test?

Could I also become tax resident in the other country?

If I become dual resident, which country wins under the double tax treaty tie-breaker?

Will my salary be taxable in the foreign country?

Will my UK employer need to operate local payroll?

Will UK PAYE continue to apply?

Can double taxation be relieved properly?

What happens to social security?

Do I need an A1 certificate or certificate of coverage?

Do I have the legal right to work from that country?

Do I have bonuses, RSUs, options or deferred compensation?

Am I a director, partner, founder or senior decision-maker?

Can I negotiate or conclude contracts?

Can my activities create a Permanent Establishment risk for the company?

Has my employer formally approved the arrangement?

Is there a written tax and remote-working policy?

These questions may sound technical, but they are practical.

They are the questions that prevent problems before they become expensive.

The worst approach is to assume that remote working is “just a lifestyle choice”.

For tax purposes, remote working from abroad is cross-border economic activity.

And cross-border economic activity has consequences.

A person may think:

“I am only working from my laptop.”

The tax authority may see something different:

“You are performing employment duties here.”
“You are creating income here.”
“You may be resident here.”
“You may owe tax here.”
“Your employer may have obligations here.”
“Your company may have a taxable presence here.”

That is the real issue.

Remote work has made life more flexible.

But tax systems are still built around residence, source, physical presence, payroll, management, control and profit allocation.

Those rules have not disappeared simply because work is now done through Teams, Zoom and a laptop.

The practical message is simple:

Working from anywhere does not mean taxed nowhere.

Before you work remotely from abroad, check the tax position.

Not after six months.

Not after the foreign tax authority asks questions.

Not after payroll has been operated incorrectly.

Not after a bonus or share award has vested.

Not after the company discovers that your personal working pattern may have created a Permanent Establishment risk.

Before.

At Vectigalis Tax, we advise individuals, directors, founders, executives and internationally mobile professionals on the UK and cross-border tax consequences of remote working from abroad.

We review the personal tax residence position, employment income exposure, double tax treaty protection, payroll implications, social security position, equity awards and, where relevant, the Permanent Establishment risk for the employer or company.

The objective is simple:

a clear, practical and defensible action plan before the issue becomes a problem.

If you are working remotely from abroad, planning to spend more time outside the UK, or allowing employees to work internationally, this is the right time to review the position.

Contact Vectigalis Tax to arrange a focused cross-border tax consultation.

Because sometimes the most expensive part of remote working is not the flight, the rent or the Wi-Fi.

It is the tax position nobody checked before switching on the laptop.
