When Do You Have to Pay for Taxes?

Taxes are an unavoidable part of life in the UK—especially if you are self-employed, a sole trader, or running your own business. However, many people are unsure when exactly they need to pay taxes and what deadlines they must meet to avoid fines or penalties.

In this blog, we’ll explain the key UK tax payment dates and provide useful resources to help you stay compliant. If you’re just starting out or already managing your tax affairs, this guide will keep you informed and on track.

[edit] Key UK Tax Deadlines

The tax year in the UK runs from 6 April to 5 April the following year. You are generally required to pay taxes based on your income during this period.

[edit] 1. Registering for Self-Employment

If you’re earning money as a freelancer, contractor, or through your own business, you need to register with HMRC. This is an essential step before submitting your tax return.

Deadline: Register by 5 October in your business’s second tax year.

[edit] 2. Self-Assessment Tax Return Deadlines

Once registered, you’ll be required to file a Self Assessment tax return. This involves reporting your income, expenses, and any tax owed.

Key Deadlines:

• 31 October: Paper tax return deadline.
• 31 January: Online tax return deadline and payment of any tax owed for the previous tax year.
• 31 July: Deadline to pay the second installment if you make payments on account.

[edit] What Happens If You Miss the Deadline?

Failing to submit your tax return or pay your tax bill on time can lead to:

• Automatic fines starting from £100
• Daily penalties after 3 months
• Interest on late payments

That’s why it’s crucial to get support from experienced professionals if you’re feeling overwhelmed.
