Dubai's lack of income tax on salaries is a big draw, but boarding the plane doesn't cut your ties with HMRC. Whether you still owe UK tax comes down to a few things: where you're treated as resident, what you leave behind in Britain, and whether you can prove when and how you left.
Settle the residency question first
Everything else depends on this. HMRC uses the Statutory Residence Test, which weighs how many days you spend in the UK, how much work you do there, and connections such as a family, a home or a job you keep. People who commute back regularly or hold onto a UK property are the ones most likely to stay resident without realising it. The move year itself may be split, so you're taxed as a UK resident only up to your departure date. Given how much rides on getting this right, it's worth having an adviser check your position before you go.
Build a paper trail
If HMRC ever challenges your non-resident status, evidence wins the argument. Hold onto your flight records, UAE visa, employment contract, tenancy agreement and removal paperwork. Once you've arrived, get your residence visa and Emirates ID sorted quickly and keep a log of every trip back to the UK, noting any days you work while there.
Let HMRC know
Most leavers who don't file tax returns use form P85. If you're already in Self Assessment, you'll report the move on your return instead. It's common to get a refund of PAYE tax overpaid in your final months.
Look at what stays in the UK
Some income keeps its UK tax treatment no matter where you live:
- Rent from UK property. This remains taxable here. Register with the Non-Resident Landlord Scheme so your letting agent or tenant doesn't have to deduct tax at source.
- UK work. Duties carried out on British soil can still be taxed.
- Pensions. Check how withdrawals will be treated once you're abroad, and whether you can keep contributing.
- Investments. ISAs, share schemes and offshore accounts each have their own rules for non-residents.
Selling assets soon after leaving is a common trap. If you return to the UK within five years, gains made while you were away can be pulled back into the UK tax net.
Inheritance tax follows you longer
This catches many people out. Since April 2025, UK inheritance tax exposure is based on long-term residence rather than domicile, and someone resident here for most of the previous 20 years can stay within scope for several years after leaving. Get this reviewed early, especially if you have significant assets.
Don't assume Dubai means zero tax
Salaries aren't taxed in the UAE, but business profits may fall under UAE corporate tax, and there are other costs and filing duties to be aware of. The UK and UAE also have a tax treaty that decides which country can tax things like dividends, interest and pensions. How it applies depends on your circumstances.
Keep on top of admin
Update your banks and investment platforms with your new tax residence, as they'll likely ask you to complete CRS or FATCA forms. You may still need to file a UK return each year if you have UK income, sell UK property, receive a notice to file, or want to claim treaty relief or a refund.
The bottom line
Most problems come from the same few mistakes: keeping too many links to the UK, visiting too often, and failing to keep records. A conversation with an adviser before you leave is far cheaper than untangling a dispute with HMRC afterwards.
