The UK tax system is designed to ensure that everyone pays their fair share, and this includes those who work multiple jobs. We won't complicate things with complex terminology. Instead, we'll give you a straightforward overview of how second job tax works. We'll also touch on the importance of UK tax return services to help you navigate this process efficiently.

Understanding Second Job Tax: A Simple Explanation

So, you've decided to take on a second job in the UK. That's fantastic! But the big question on your mind is probably, "How much tax will I have to pay?" Don't worry; we've got you covered with a clear explanation.

How Your Income Affects Second Job Tax

The amount of tax you pay on your second job is directly linked to how much you earn from both of your jobs. This means your income from your first job combines with what you make from your second job.

Accurate tax reporting ensures you pay the right amount of tax based on your total income. To make this happen, you need to fill out something called a "tax return."

The HMRC Self-Assessment Tax Return

HMRC (Her Majesty's Revenue and Customs), the authority responsible for managing taxes in the UK, uses a system called "self-assessment," which means you take the lead in reporting your income and expenses. Don't worry, UK tax return services like Taxd are here to assist you, ensuring you navigate this process without unnecessary stress.

Non-Resident Tax Return

Now, if you're a non-resident landlord, you might be wondering if this changes the game when it comes to your second job tax. The good news is that, in most cases, being a non-resident doesn't significantly alter how you pay tax on second job income in the UK. The principle remains the same – it's all about your total earnings.

How Much Tax Will You Pay On A Second Job?

HMRC will consider one job to be your primary source of income, and you will receive a personal allowance for it. The usual Personal Allowance is £12,570, and earnings up to this amount are tax-free.

Earnings over the Personal Allowance threshold are subject to Income Tax at:

  • Basic Rate: Applies to incomes between £12,501 and £50,270 at a rate of 20%.
  • Higher Rate: Applies to incomes between £50,270 and £125,140 at a rate of 40%.
  • Additional Rate: Applies to incomes over £125,140 at a rate of 45%.

HMRC would often consider your higher-earning job to be your primary source of income and your second job to be a supplemental source if your combined income from the two jobs exceeds £12,570. Your second work will typically be subject to 20% basic rate taxation, with your personal allowance being deducted from your primary income.

Note: If you make less than £12,570 from both jobs, ask HMRC to split your Personal Allowance between them to reduce your tax bill.
