Under new OECD rules, HMRC will soon be able to share and receive detailed property ownership data with overseas tax authorities. **If you own property abroad—or if you’re a non-UK resident with UK property—this is something you need to know.** --- ### **What’s Happening?** The UK Treasury has confirmed that the country will sign up to the **Multilateral Competent Authority Agreement on Automatic Exchange of Readily Available Information on Immovable Property (IPI MCAA)**. In simple terms, tax authorities in participating countries will automatically exchange information about real estate ownership. So far, **26 countries** have signed up, including the UK, France, Germany, Spain, and others. However, some major jurisdictions—such as the **US, Australia, Switzerland, UAE, India, Bulgaria, and Pakistan**—are not yet on board. These are places where many UK citizens hold property, so expect further developments. --- ### **Why Should You Care?** This isn’t just a technical tax update—it could have real consequences for you. HMRC will gain visibility over overseas property owned by UK residents, making it harder to hide rental income or capital gains. Likewise, foreign tax authorities will learn more about UK property owned by their residents. If you’ve been relying on secrecy or assuming HMRC won’t find out about your overseas assets, think again. As one tax expert put it: **“It’s a question of when, not if HMRC will find out.”** --- ### **When Will It Start?** The first data exchanges are expected in **2029 or 2030**, giving property owners time to prepare. But don’t wait until the last minute—HMRC already uses domestic data sources like the **Land Registry** and the **Register of Overseas Entities** to identify potential non-compliance. This new agreement simply extends that reach globally. --- ### **What Does This Mean for You?** If you own property overseas, here’s what you should do now: ✔ **Review your UK tax position**: Are you declaring rental income and capital gains correctly? ✔ **Seek professional advice**: Don’t assume you’re compliant—rules on foreign property can be complex. ✔ **Plan ahead**: Transparency is increasing, and penalties for non-compliance can be severe. --- ### **For Expert Advice – Contact Ttam Ltd** Global tax transparency is tightening, and HMRC will soon have access to more data than ever.

The message is clear: **global tax transparency is here to stay**. As Manal Corwin of the OECD said: **“By extending automatic exchange to real estate, jurisdictions are helping to shed light on an area that has historically been opaque.”** --- #### **Bottom line:** If you own property abroad—or have overseas interests—**now is the time to act**.
