The UK Income Tax System: A Guide for New London Residents

A crucial aspect of understanding the UK income tax system obligations involves familiarizing yourself with your tax code. The tax code is issued by HM Revenue and Customs (HMRC) and communicated to your employer to determine how much Income Tax should be deducted from your salary. Essentially, your tax code reflects your Personal Allowance—the amount you can earn tax-free each year—and any additional allowances or deductions specific to your financial situation.

For most individuals, the tax code starts with a number and ends with a letter. The number represents your tax-free Personal Allowance, divided by 10, and the letter indicates any situations that affect the allowance. It’s imperative to ensure that your tax code is accurate to prevent under or overpaying tax. If you’re moving to London and starting a new job, your employer will typically use a ‘temporary’ tax code until HMRC provides them with the correct one. This process is part of the PAYE system, enabling tax deductions directly from your earnings, ensuring that you pay the right amount of tax over the year.

Should you notice discrepancies or if your financial situation changes (e.g., changing jobs, receiving additional income), it’s essential to inform HMRC to update your tax code.
