It’s a question almost every client asks when they plan a move overseas:

“Do I have to sell my UK investments before I go?”

The short answer is — not necessarily.

But once you’re no longer a UK resident, the rules around your ISAs, pensions, and investment accounts change.

At Arthur Browns Wealth Management, we help clients understand what can stay, what must change, and what becomes tax-inefficient once you live abroad. Here’s a simple breakdown.

---

ISAs: You Can Keep Them — But You Can’t Add to Them

You can keep your existing ISAs after leaving the UK, but you can’t pay any new money in.

HMRC rules are clear:

“If you move abroad, you can keep your ISA open but you cannot put money into it unless you are resident in the UK.”

That means:

• Your ISA investments can continue to grow tax-free in the UK.

• However, your new country of residence may still tax that growth.

• You can start contributing again if you return to UK tax residency.

If you’re moving to Europe, such as Portugal, Spain or France, each country treats ISAs differently. For example, Portugal often doesn’t recognise the UK’s ISA tax wrapper, meaning income or gains could be taxable locally.

It’s wise to review your ISA holdings with a cross-border financial adviser before you go.

Pensions: Usually Safe, But Check Access Rules

Your UK pension remains governed by UK rules, even if you live abroad.

You don’t have to transfer it — and in many cases, it’s better not to.

However:

• Some UK pension providers will not deal directly with you if you’re an overseas resident.

• Taking benefits (like drawdown or annuities) can trigger cross-border advice requirements.

• The tax-free cash you get in the UK may not be tax-free in your new country.

If you plan to access your pension while living overseas, speak to a firm regulated both in the UK and your country of residence.

Our guide on International SIPPs explains how these can offer flexibility for expats.

General Investment Accounts (GIAs): Review for Tax Efficiency

If you hold a UK general investment account, you can technically keep it open — but there are two main issues:

1. Tax reporting: You may need to declare income and gains in your new country, even if the investment stays in the UK.

2. Platform restrictions: Some UK investment platforms block non-UK residents from holding or trading due to compliance and MiFID rules.

If your provider won’t allow you to stay on, consider an offshore investment platform based in a regulated jurisdiction (for example, Dublin or Luxembourg) where your assets can be held in GBP, EUR, or USD.

The MoneyHelper expat investment guide has an overview of how residency affects investments.

UK Property and Rental Income

You can keep UK property when you move abroad — many expats do.

However, rental income is still taxable in the UK, even if you’re a non-resident.

You’ll need to:

• Register under the Non-Resident Landlord Scheme (HMRC Guidance)

• File annual UK tax returns for rental income

• Report that same income in your new country (often with relief under a double-taxation treaty)

If you plan to sell your UK property after moving, note that you may still owe UK Capital Gains Tax (CGT) on the sale.

Banking and Currency Management

You don’t necessarily have to close your UK bank accounts — but it’s worth having a multi-currency setup once you’re overseas.

Consider:

• Opening an international or offshore account that lets you hold GBP, EUR, and USD.

• Using regulated FX platforms to transfer funds at competitive rates.

• Avoiding the temptation to hold all savings in GBP if you’ll be spending in euros or dollars.

Good currency management can protect you against exchange-rate volatility, especially for pensions or rental income received from the UK.

The Telegraph’s expat money guide offers practical examples of how to manage currency exposure.

Investments That May No Longer Be Suitable

Once you move abroad, some investments become problematic:

• UK onshore funds that automatically deduct UK tax.

• Tax-sheltered products (like Venture Capital Trusts) that only benefit UK residents.

• ISAs and LISAs that lose their tax advantage abroad.

• Insurance bonds or legacy offshore products with high commission and exit fees.

It’s often better to simplify your portfolio or consolidate it into a transparent, regulated international structure before you move.

How to Review Your Portfolio Before Moving

Before relocating, take these steps:

1. List all your UK financial products — pensions, ISAs, GIAs, property, bank accounts.

2. Identify which ones you can legally keep and which may be restricted.

3. Check local tax rules in your destination country.

4. Speak to a dual-regulated adviser who can help you restructure efficiently.

At Arthur Browns Wealth Management, we offer pre-departure financial reviews for clients moving overseas. We’ll explain what you can keep, what needs changing, and how to stay compliant on both sides of the border.

The Bottom Line

You don’t need to start from scratch when you move abroad — but you do need to plan.

Many UK investments can stay in place, but their tax treatment, accessibility, and suitability will depend on where you live.

By reviewing your assets, getting proper advice, and understanding both UK and local regulations, you can keep your money working efficiently — wherever you live.
