How do I pay Corporation Tax?

Paying Corporation Tax Bill

Corporation Tax is a tax that limited companies in the UK need to pay on their profits. Unlike Income Tax, which is automatically deducted from salaries through PAYE, Corporation Tax is aimed specifically at businesses. If you’re running a limited company, you’ll need to calculate your tax based on your profits, file a return to HMRC, and pay corporation tax by the deadline.

Making sure to pay Corporation Tax before the deadline is important to avoid any financial penalties and interest fees. HMRC imposes fines for late payments, and these can really add up if you’re not careful. Plus, falling behind on payments can hurt a company’s cash flow and tarnish its financial reputation.

Who Needs to Pay Corporation Tax?

All UK-registered limited companies must pay Corporation Tax on their profits. This includes earnings from:

  • Trading activities.
  • Selling assets like land, property, or shares (capital gains).
  • Investments or interest earned.

Corporation Tax applies to:

  • Limited companies registered in the UK
  • Foreign companies with UK branches that make a profit in the country
  • Clubs, cooperatives, and trade associations that generate taxable profits

If a company makes a profit, it must report this to HMRC and pay the correct amount of Corporation Tax. Even if a business does not owe any tax, it must still file a tax return.

How to Pay Corporation Tax

Paying Corporation Tax is an important duty for businesses in the UK. If your company turns a profit, you’ll need to figure out how much tax you owe and make sure to pay it to HMRC by the deadline. Here are steps to help you follow the process of paying Corporation Tax correctly.

1. Know Your Corporation Tax Payment Deadline

The deadlines for Corporation Tax depend on your company’s financial year. You’ll need to pay your tax nine months and one day after the end of your accounting period.

For instance: If your accounting period wraps up on 31st March, your tax payment will be due by 1st January of the following year. If your profits exceed £1.5 million, you might have to make payments in instalments.

2. Figure Out How Much You Owe

To determine your Corporation Tax liability, you’ll need to calculate your company’s taxable profits. Taxable profits include:

  • Trading profits from your core business activities
  • Income from investments like interest or dividends
  • Chargeable gains from selling assets such as property or equipment

What Can Lower Your Taxable Profits?

  • Allowable business expenses (like wages, rent, and office costs)
  • Capital allowances for equipment and machinery
  • R&D tax relief if your business invests in innovation

Make sure to keep precise financial records so you can easily track your income and expenses. This way, you’ll be able to report the right amount to HMRC, helping you steer clear of underpaying or overpaying.

3. Get Your Corporation Tax Return Ready

To pay Corporation Tax, you’ll need to fill out a Company Tax Return (CT600). This return informs HMRC about your company’s profits and the tax owed.

Steps to Prepare Your Tax Return:

  • Gather Financial Information: Collect all records of income, expenses, and allowances.
  • Complete the CT600 Form: Use HMRC’s online portal to fill out the form.
  • Submit the Return: Make sure to file the return online by the deadline, even if your company doesn’t owe any tax.

4. Calculate Your Corporation Tax Liability

Corporation Tax rates vary based on your company’s profits. For the 2024/25 tax year:

  • 19% if profits are £50,000 or less (small profits rate)
  • 25% if profits exceed £250,000 (main rate)
  • Marginal Relief applies if profits fall between £50,000 and £250,000.

Use corporation tax calculator to avoid manual calculation and work out the tax you owe in minutes.

5. Pay Your Corporation Tax Bill

Once you’ve figured out how much you owe, you can pay it using one of HMRC’s approved payment methods. Keep in mind that each method has its own processing time, so it’s a good idea to pay early to ensure you meet the deadline.

If you think you might have trouble making a payment, contact HMRC right away to talk about potential arrangements.
