Lakshmi Mittal and the Great British Non-Dom Tax Drama

Lakshmi Mittal and the Great British Non-Dom Tax Drama

As soon as billionaires start moving out, something strange is afoot. Lakshmi Mittal, the super-rich steel magnate behind ArcelorMittal--the world's largest steel company--is reported to be considering leaving Britain due to a potential end of non-domiciled (non-dom) tax status benefits in Britain.   

Who Is Lakshmi Mittal Anyway?  

Mittal stands out as being something special among his fellow billionaires; for years, he's lived comfortably in Britain while taking advantage of non-dom tax arrangements that enable individuals (like himself) to avoid UK taxes on foreign income as long as it was spent within British borders.  

But these cosy days are over!  

What Has Changed?  

Starting April 2025, the UK will transition away from its non-dom system and toward something much less generous.  

Key changes will include:  
  • End of Non-Dom Era: The remittance basis of taxation will be replaced by a new four-year exemption applicable to foreign income and gains from 6 April 2025. 
  • Global Assets Affected by UK Inheritance Tax: Transition to residence-based system for inheritance tax means that after being resident 10 out of 20 years, worldwide assets will be liable for IHT. 
  • Remittance Basis—Gone: Previously, non doms only paid tax on foreign earnings if remitted to the UK. Though there are transitionary rules to ease the impact, basically now, wherever you earn income, the UK taxman wants a share.   
Simply put, the party is officially over now folk like Mittal are wondering whether staying put makes any sense.  

Where Might the Wealthy Go?  

When your fortune is at stake, you don't make decisions at random; that is why HNWIs such as Mittal are keenly scrutinising places that might allow them to keep more of their cash safely:  
  • UAE: No income tax, inheritance tax or wealth tax applies in this region.  
  • Portugal: Thanks to its Non-Habitual Residency scheme, sunny Portugal has become an appealing location for individuals who seek tax benefits without compromising on lifestyle.  
  • Switzerland and Monaco: Monaco has long been considered a tax haven because of its favorable personal and corporate tax rules. The country does not tax individuals on their income, and corporations within the country have favourable tax treatment.  
  • Italy: allows for long-term residence and access to Schengen countries. Under certain circumstances, a flat rate of tax of 7% on all foreign-sourced income is available to new residents of Italy. 

Why Should the UK Worry?   

Britain's Reputation at Risk  
Packing their bags publicly doesn't exactly send out the message that Britain is ready for business; Mittal leaving could prompt other wealthy individuals to consider whether this country remains attractive.  

Money Matters  
Every time a billionaire leaves the UK economy, their absence leads to reduced investments, lower donations to charity and less lavish spending - not just with regards to taxes but also economically.  

Politics  
The government could run into trouble if new policies are seen to push away wealthy donors with money - not exactly an ideal recipe for voter appeal! 
   
What should HNW people be Doing Now?  
  • Verify Your Status: Evaluate whether your current tax status remains advantageous under these new circumstances.  
  • Clarifying Your Tax Exposure Globally: Fully understand the tax repercussions associated with maintaining or cutting ties to the UK.  
  • Consider Alternatives: Assess potential jurisdictions such as the UAE or certain European nations that offer clearer tax regimes without inheritance or wealth taxes.  
Final Thoughts  

Mittal's potential exit encapsulates more than simply his tax bill; it spotlights a wider anxiety amongst wealthy individuals Decisions like these require careful thought, proactive planning, and expert advice.

If you’ve been hearing more about private banks, investment advisers, and wealth managers setting up shop in Dubai, you're not imagining it. Dubai has become one of the fastest-growing wealth hubs in the world, especially for British and European advisers. In the last year alone, over 60 new wealth management firms have opened offices in Dubai’s International Financial Centre (DIFC). But why is this happening, and what does it mean if you're a high net worth individual , entrepreneur, or investor living in the UAE? Why Dubai? Dubai offers something many wealth managers are now struggling to find elsewhere: a stable, tax-efficient , and business-friendly environment.

We all think about the future, but how many of us feel confident about our retirement savings? In the UAE, that question is becoming more urgent. A new report shows that more people in the UAE, especially experienced employees and professionals, are asking for better, more personalised retirement planning. They don’t just want end-of-service benefits. They want flexibility, investment choices, and long-term financial security. This shift is important. It’s not just about pensions . It’s about how people feel about their jobs, their financial freedom, and their lives after work. What the Report Found The research, carried out by recruitment experts in the UAE, found that: Many mid-to-senior-level professionals now want a tailored approach to retirement savings. People are asking employers for more investment options, not just a lump sum at the end. There is a growing interest in structured retirement accounts, including schemes where employers contribute monthly, like pensions in the UK or US. It’s a signal that the typical end-of-service benefit (gratuity) may no longer be enough for the modern workforce. The Current Retirement Model in the UAE Right now, most private sector workers in the UAE receive an End-of-Service Benefit (EOSB). This is a lump sum based on how long you've worked for your employer and your final salary. But: It’s not invested, so the value doesn’t grow with time. You only receive it when you leave the company. If a company closes down or faces financial trouble, you may lose out. While the UAE has made improvements, such as introducing savings-style EOSB schemes, many companies still use the traditional model. Why Employees Are Asking for More Here are just a few reasons UAE professionals want better retirement planning: 1. Job Security Is Less Certain People change jobs more often than they used to. Relying on a lump sum after years of service isn’t practical for mobile careers. 2. Higher Earnings = Higher Expectations Professionals in sectors like tech, finance, and consulting are earning more, and they want retirement planning to match their income and ambitions. 3. Inflation and Cost of Living Even in a tax-free environment, the long-term cost of living matters. A static lump sum at the end of your career doesn’t keep up with real-world inflation. 4. More Global Workers Many people in the UAE have worked in multiple countries. They’re familiar with international pension schemes, and they want similar options here. What Are the Alternatives? Several companies and free zones in the UAE are already offering new models for retirement planning: Monthly savings schemes with employer contributions Access to regulated investment funds tailored to retirement Portable savings accounts that follow you between jobs Dubai International Financial Centre (DIFC) launched the DIFC Employee Workplace Savings (DEWS) Plan, which has been a model for reform. Other areas may follow suit. What You Can Do Whether your employer offers advanced schemes or not, you can still take control of your retirement plan: Start a private pension or regular investment plan with expert advice Set up a monthly savings goal, even if it’s small to start Ask your employer if they’re willing to make monthly contributions Consider tax and currency implications if you plan to retire abroad Final Thoughts The way people think about retirement in the UAE is changing, and fast. It’s no longer about waiting for a lump sum and hoping it’s enough. UAE residents want to invest, plan ahead, and build financial independence while they’re still working. If you're living and working in the UAE, the best time to plan for retirement isn't when you're 60. It’s now! We help people across the UAE, UK and other jurisdictions set up private pension plans, understand retirement investments, and structure savings that work whether you retire in Dubai, UK or move abroad. Speak to one of our advisers today for clear, practical help with your long-term planning.
