UK tax when you live abroad
Non-UK residents pay the 2% non-resident SDLT surcharge on top of the higher rates for additional properties in England and Northern Ireland. Rental income is taxed in the UK under the Non-Resident Landlord Scheme; register with HMRC to receive rent gross.
Whether it is also taxed where you live depends on that country's double taxation agreement with the UK — take local tax advice.

Rate context and outlook
Expat lenders repriced alongside the wider market in September: HSBC raised its ranges three times and Molo repriced its buy-to-let range from 7 September.
For EU residents, CRD VI rules mean Skipton International no longer takes new applications, so HSBC Expat, Molo Finance and NatWest International are the main routes. Bank Rate is 3.75%, next decision 5 November.
