Banking, Taxation & Finance System in London – Expat Guide

Relocating to London for work or family life means adjusting to more than just a new culture. Understanding the UK banking system, taxation rules, and how to manage your finances as an expat in London is essential for a smooth transition.

This guide explains everything from opening a bank account to paying taxes and budgeting, so you can feel confident about managing your money in one of the world’s leading financial hubs.

Opening a Bank Account in London as an Expat

One of the first steps in settling into life in the UK is opening a UK bank account. It makes paying rent, receiving your salary, and managing expenses much easier.

Requirements for a UK Bank Account

Proof of identity (passport, visa, or BRP card)

Proof of UK address (rental contract, utility bill, or employer letter)

Some banks offer expat accounts if you don’t yet have a local address

Popular Banks in London for Expats

• HSBC Expat – tailored accounts for international professionals
• Barclays – well-known for easy online banking and global services
• Lloyds Bank – flexible personal and joint accounts

Monzo & Revolut – digital banks with quick setup, useful for newcomers

💡 Tip: Many expats start with an international or digital bank, then switch to a UK high-street bank once they have a permanent address.

Taxation in London for Expats

Living and working in London means paying UK taxes, which are deducted automatically from your salary through the PAYE (Pay As You Earn) system.

UK Income Tax for Expats

• Income tax is progressive, ranging from 20% to 45%, depending on your salary.
• If you earn £70,000+, you’ll likely fall into the 40% tax bracket for income above the basic threshold.
• Some employers offer tax equalisation packages to balance home vs. UK tax differences.

National Insurance Contributions (NICs)

NICs fund the NHS, pensions, and social benefits.

Both you and your employer contribute.

Double Taxation Treaties

The UK has treaties with many countries to prevent expats from being taxed twice.

Check with HMRC or a tax advisor to confirm your country’s status.

Filing Taxes as an Expat

Most employees don’t need to file a tax return unless they have additional income (rental, investments, overseas earnings).

Expats with complex finances may need to complete a Self-Assessment tax return.
