Tax Guide for Non-Residents Buying Buy-to-Let Property in the UK

Updated: Jun 21

The UK property market remains an attractive investment opportunity for non-residents, particularly those looking to invest in buy-to-let properties. However, recent years have seen significant changes in the tax landscape, impacting how non-residents manage their investments.

We've received numerous inquiries from clients seeking clarity on these changes and how best to navigate the complexities of UK property taxes. This post aims to provide an overview of the current tax situation for non-residents, focusing on the offsetting of mortgage finance and the most tax-efficient structures for holding buy-to-let properties.

Income Tax

  1. Rental Income Tax: Non-residents must pay income tax on rental income from UK properties. The rate depends on the income band:

  • Basic rate: 20%

  • Higher rate: 40%

  • Additional rate: 45%

2. Allowable Expenses: Non-residents can deduct certain expenses from their rental income, including:

  • Property management fees

  • Repairs and maintenance

  • Insurance

  • Legal fees for leases

Mortgage Interest Relief

  • Post-2017 Restrictions: The ability to offset mortgage interest against rental income has been reduced. Non-residents can no longer deduct full mortgage interest from rental income. Instead, they receive a tax credit at the basic rate (20%) on the interest paid.

Capital Gains Tax (CGT)

  • Non-residents are liable for CGT on the sale of UK residential property. The rates are:

  • Basic rate: 18%

  • Higher rate: 28%

  • The gain is calculated from April 2015 for properties owned before this date.

Inheritance Tax (IHT)

  • UK properties are subject to IHT, regardless of the owner's residence. The standard rate is 40% above the nil-rate band (£325,000 as of 2023).

UK property Tax-Efficient Structures

  1. Individual Ownership:

  • Simplest form, but less tax-efficient due to higher income tax rates and limited mortgage interest relief.

2. Limited Company:

  • Benefits:

  • Corporation tax rate of 19% (lower than higher rates of income tax).

  • Full mortgage interest relief as a business expense.

  • Easier to manage multiple properties.

  • Potential for tax-efficient profit extraction via dividends.

  • Drawbacks:

  • Administrative burden and costs.

  • Additional tax on dividends when paid to shareholders.

  • Potential double taxation on disposal (corporation tax on gains, then income tax on dividends).

3. Partnerships (Limited Liability Partnership - LLP):

  • Benefits:

  • Flexibility in profit distribution.

  • Transparent tax structure (income tax on individual partners).

  • Drawbacks:

  • Partners are taxed on their share of profits, potentially at higher personal rates.

4. Trusts:

  • Can be used for estate planning and IHT mitigation.

  • Complex and subject to specific tax rules.

Working with a Private Bank


  • Personalized Financial Advice: Private banks offer tailored financial planning and tax advice.

  • Access to Financing: Competitive mortgage rates and financing options for high-value properties.

  • Asset Management: Comprehensive services, including property management and investment strategies.


  • Costs: Private banking services come with fees, which need to be weighed against the benefits.

  • Qualification: Minimum asset requirements, often starting at £1 million.
