What Is Dual Tax Residency?

Dual tax residency takes place when a person meets the standards to be considered a tax resident in two or more nations simultaneously. This can happen for various reasons, such as:

  • Living in more than one country during a whole tax year
  • Earning income in more than one jurisdiction
  • Owning residential property in two countries
  • Living in a country for a specific number of days
  • Keeping a permanent home or having family ties in a number of countries

How Does Dual Residency Affect Expats?

For expats, particularly ones investing in property or applying for an expat buy-to-let mortgage UK, dual residency can complicate tax reporting and financial obligations. You may be required to:

  • File tax returns in both countries
  • Report global earnings in each jurisdiction
  • Pay tax in both nations, except when relief is available
  • Navigate double taxation agreements (DTAs)

This can impact not only your disposable income but also your capacity to meet certain lending criteria when you’re applying for expat BTL mortgages.

What Is a Double Taxation Agreement?

Fortunately, many nations including the UK have Double Taxation Agreements (DTAs) in place. These treaties ensure that people are not taxed twice on the same income.

If you’re deemed to be a resident in more than one country, the DTA regularly includes a tie-breaker rule that uses certain criteria to decide which one has priority when it comes to your tax liabilities. These standards usually consist of:

  • The location of your permanent residence
  • Where your main interests are, including your family, business and financial interests
  • Your main place of residence
  • Your nationality

Finding out how a DTA applies to you can help you structure your earnings and investments effectively, especially while looking for suitable expat mortgage lenders UK, who may help you manage your global financial profile.

How Dual Residency Impacts Expat Mortgage Applications

If you are considered to be a dual resident, this can affect how lenders view your application. UK expat mortgage lenders commonly need a clear understanding of your tax position when:

  • You have earnings from abroad
  • You’re using services outside the United Kingdom
  • You’re purchasing a property as an investment

Whether you’re applying for a buy-to-let mortgage UK expat product or a residential mortgage, creditors will take a close look at your income balance, tax liabilities and capacity to repay.

Steps to Take if You Are a Dual Tax Resident

To minimise complications and keep yourself compliant, here are the key steps you should take if you’re a dual resident, or suspect that you are:

1. Get Professional Tax Advice

Tax laws can be highly complex and specific to each country. Get help from a worldwide tax advisor who can assess your situation and give you recommendations on DTAs and complying with your responsibilities.

2. Disclose All Income Accurately

When disclosing information about your income for a mortgage application, be completely transparent about your earnings. This will help lenders to determine affordability and avoid delays with your application.

3. Choose the Right Lender

Not all lenders are set up to deal with complex expat mortgage applications. Work with experts like Expat Mortgages UK, who understand the nuances of expat BTL mortgages and can direct you to the most suitable products.

4. Keep Your Documents Organised

If you’re a dual resident, you may need to provide extra documentation such as tax returns from both international locations, proof of address and bank statements. Good organisation will make the application process simpler.

Credit Score Challenges: Getting a UK Mortgage While Living in the US

April 21, 2025

Buying a house in the UK whilst living in the US can be challenging, particularly when it comes to acquiring a mortgage. One of the biggest issues you could face is your credit score. UK lenders look at your domestic credit history when deciding whether to approve a mortgage, but they don’t consider US credit scores.

If you have been a resident of the US for a long time, you may not have an active credit record in the UK, and this can make it harder to be accepted. Even if you do have a stable income and a substantial amount of savings, you may be still considered as high-risk by lenders.

How Do Credit Scores Work in the UK?

A credit score is a number that tells you how reliable you are as a borrower. UK lenders will use this score to decide whether to approve your mortgage application.

  • Score Range: A different score range is used by each of these CRAs. However, a score more than 700 is generally considered to be good and should help secure approval for your mortgage.

  • Higher Deposit Amounts: Some lenders may ask for a higher deposit (20-40%) to reduce their level of risk.

  • Pay Off Old Debts: If you have existing balances on any old UK credit cards or loans, settle them as quickly as possible. Any outstanding debts can harm your credit rating and make it harder for you to take out a UK expat mortgage.
