Paying Corporation Tax is one of the routine responsibilities of running a UK limited company. Yet choosing the wrong payment method, using an incorrect reference number or leaving a bank transfer until the last minute can turn a straightforward tax payment into an unnecessary problem.

The good news is that HM Revenue & Customs (HMRC) offers several ways for companies to pay Corporation Tax, including online banking, Faster Payments, CHAPS, debit or corporate credit cards, and Direct Debit. The important point is that different payment methods take different amounts of time to reach HMRC. If your Corporation Tax deadline is approaching, that timing matters.

This guide explains the main Corporation Tax payment methods, when each is appropriate, how to find the correct payment reference, how long payments take, and what happens if you pay late.

What Is Corporation Tax?

Corporation Tax is a tax charged on the taxable profits of companies and certain other organisations operating in the UK. A limited company generally calculates its Corporation Tax liability through its Company Tax Return and pays the amount due to HMRC. Corporation Tax is separate from other obligations such as VAT, PAYE and National Insurance.

For most companies, the Corporation Tax payment deadline is nine months and one day after the end of the accounting period. For example, if a company's accounting period ends on 31 March, its Corporation Tax payment will normally be due on 1 January.

Large companies can have different payment arrangements, including quarterly instalment payments, so the standard deadline does not apply in every case. The key lesson is simple: know your company's Corporation Tax payment date before choosing how to pay.

What Are the Main Corporation Tax Payment Methods?

HMRC currently provides several payment options. The most suitable choice depends on how quickly the payment needs to reach HMRC, the company's banking arrangements and whether you want to automate future payments. The principal options are:

HMRC specifically advises companies to choose a payment method that gives sufficient time for the money to reach them. That distinction becomes particularly important around weekends and UK bank holidays.

1. Pay Corporation Tax Through Your Online Bank Account

One of the simplest options is HMRC's online payment service, which allows you to approve the payment directly through your online or mobile banking. You start the Corporation Tax payment with HMRC and select the option to pay through your bank account. You are then directed to your bank to authorise the transaction. HMRC says the payment is usually instant, although it can take up to two hours to appear in the account.

When is this useful?

This method is particularly convenient when:

• Your payment deadline is close.
• You want to make a one-off payment.
• You do not want to set up a Direct Debit.
• Your business uses online banking.
• You want a straightforward electronic payment trail.

It can also be useful for overseas founders managing a UK company, provided the relevant banking arrangements support the payment process.

2. Faster Payments and CHAPS

Companies can also pay HMRC through online or telephone banking using Faster Payments or CHAPS. These are useful when the company wants to make a bank transfer directly rather than using HMRC's online bank-payment journey.

Faster Payments are generally suitable for ordinary business tax payments where speed is important. CHAPS can be appropriate for high-value or time-critical payments. HMRC categorises online or telephone banking using Faster Payments or CHAPS as a same-day or next-day payment method.

The critical detail: use the correct reference

Your Corporation Tax payment must be allocated to the correct accounting period. HMRC uses a 17-character Corporation Tax payment reference for the relevant accounting period. The reference can be found on your notice to deliver a Company Tax Return, HMRC reminders or within your HMRC online account.

The reference changes between accounting periods. That means you should not assume the reference used for last year's Corporation Tax payment is still valid for this year's payment.

3. Paying Corporation Tax by Debit or Corporate Credit Card

HMRC also accepts online card payments. There is an important distinction here:

• Personal debit cards: no fee.
• Corporate debit cards: a fee applies.
• Corporate credit cards: a fee applies.
• Personal credit cards: cannot be used.

The card fee for corporate cards is non-refundable. HMRC accepts the payment on the date you make it, including weekends and bank holidays, rather than the date the money subsequently reaches HMRC's account.

When does card payment make sense?

Card payment can be useful when:

• The deadline is imminent.
• You need confirmation that payment was initiated that day.
• The company has sufficient card facilities.
• The card fee is acceptable.

However, using a corporate credit card simply to delay payment can become expensive if it creates financing costs. The tax liability still needs to be paid, and card charges do not remove the underlying obligation.

4. Paying Corporation Tax by Direct Debit

Direct Debit is particularly useful for companies that want to make recurring tax payments easier to manage. You can set up a Direct Debit through your company's HMRC online account. However, the timing matters. HMRC says:

• A new Direct Debit should be allowed 5 working days to process.
• Once a Direct Debit has already been authorised, payments generally take 3 working days.
• Direct Debit cannot be used for payments over £20 million.

You also need to use the correct 17-character Corporation Tax payment reference for the accounting period being paid.

Why businesses use Direct Debit

The main advantage is convenience. Instead of remembering to initiate every payment manually, an authorised Direct Debit can make the process more predictable. It can be especially useful where a company has:

• Regular Corporation Tax liabilities.
• An established finance process.
• A dedicated company bank account.
• An accountant or finance manager monitoring HMRC obligations.

However, Direct Debit should not be treated as an excuse to stop checking the company's tax position. You remain responsible for ensuring that sufficient funds are available and that the correct liability is being settled.

5. Paying by Bacs

Bacs is another option for paying Corporation Tax through online or telephone banking. HMRC generally classifies Bacs payments as taking 3 working days. This makes Bacs less suitable when you are already close to the deadline. If your Corporation Tax payment is due tomorrow, for example, choosing a three-working-day method could leave you exposed to late payment interest. Bacs can make more sense when the payment is planned well in advance.

How to Choose the Right Corporation Tax Payment Method

A useful way to decide is to work backwards from the deadline.

If the deadline is several weeks away

You have plenty of options. You could use:

• Direct Debit
• Bacs
• Faster Payments
• Online bank payment
• Card

If the deadline is a few working days away

Use a method that provides sufficient clearance time. Faster Payments, online bank payment or another fast method may be preferable.

If the deadline is today

Choose a payment method that HMRC recognises as sufficiently fast and carefully follow its instructions. HMRC states that companies should make sure their payment reaches HMRC by the deadline. If the deadline falls on a weekend or bank holiday, companies should generally ensure payment reaches HMRC on the previous working day, although there are specific rules for Faster Payments.

What Is the Corporation Tax Payment Reference?

The payment reference is one of the easiest details to get wrong. HMRC uses a 17-character reference associated with the Corporation Tax accounting period you are paying. It is not simply a permanent reference for the company. This distinction matters because the payment reference changes for different accounting periods. HMRC warns that using the wrong reference can delay allocation of the payment or cause it to be applied incorrectly.

Where can you find it?

You can normally find the reference:

• On your notice to deliver a Company Tax Return.
• On HMRC correspondence or reminders.
• In the company's HMRC online account.

Before submitting a bank transfer, compare the reference against the accounting period you are actually paying.

What Happens If You Pay Corporation Tax Late?

If Corporation Tax is paid after the normal due date, HMRC can charge late payment interest. The interest generally runs from the normal payment due date until the date the tax is paid. As of 9 January 2026, HMRC's published late-payment interest rate for the relevant Corporation Tax payment category is 7.75%, although rates can change when the underlying Bank of England rate changes.

This is why the payment method matters. A company might have enough money in its bank account to pay its tax but still pay late because the transfer was initiated too late.

A practical example

Imagine a company owes £12,000 in Corporation Tax, due on 1 January. The director initiates a Bacs payment on 31 December without checking how long the payment will take.

If the money does not reach HMRC by the required date, the company may incur late payment interest even though the director technically initiated the transfer before the deadline. The better approach is to work backwards and select a payment method based on its expected processing time.

Corporation Tax Payment vs Corporation Tax Return

A common mistake among new directors is treating the tax return and tax payment as the same obligation. They are separate. A company normally has to:

1. Prepare its accounts and Corporation Tax calculation.
2. File its Company Tax Return with HMRC.
3. Pay the Corporation Tax due by the appropriate deadline.

For most companies, the tax payment deadline is earlier than the deadline for filing the Company Tax Return. This means a company should not wait until it is ready to file its tax return before thinking about the tax payment. Your accountant may estimate the Corporation Tax liability before the final return is filed, allowing the company to arrange payment in good time.

What If the Company Cannot Pay Its Corporation Tax Bill?

If your company cannot pay its Corporation Tax in full, do not simply ignore the deadline. The first step is to establish:

• How much is owed.
• When it is due.
• Why the company cannot pay.
• How much cash is available.
• Whether customers are expected to pay soon.
• Whether other liabilities can legally and commercially be rescheduled.

Contacting HMRC promptly can be important where a company is experiencing genuine cash-flow difficulties. Directors should also remember that inability to pay Corporation Tax can be a warning sign of broader financial distress. If the company is struggling to pay multiple creditors, professional insolvency advice may be appropriate. This is particularly important because directors have duties to the company and, when insolvency is a concern, creditors' interests become increasingly significant.

How Global Founders Can Manage UK Corporation Tax Payments

A UK company does not need all of its directors to live in the UK, but international founders should pay particular attention to administration. If you are managing a UK company from overseas, build a simple compliance system covering:

• Corporation Tax deadlines.
• Company Tax Return filing.
• Companies House filing deadlines.
• VAT obligations, if registered.
• PAYE obligations, if the company employs people.
• Bank account balances.
• HMRC correspondence.
• Payment references.

The biggest risk for an overseas director is often not the tax itself but assuming that someone else is monitoring the company's UK obligations. A UK company formation and management platform such as IncorpUK can be part of a broader administrative setup for global founders, but responsibility for meeting tax obligations ultimately remains with the company and its directors.

A Simple Corporation Tax Payment Checklist

Before paying HMRC, check these seven points:

1. Confirm the accounting period

Make sure you are paying the correct Corporation Tax liability.

2. Confirm the amount

Check the calculation or latest HMRC statement.

3. Confirm the deadline

Do not rely solely on memory.

4. Get the correct 17-character reference

The reference is linked to the accounting period.

5. Choose a suitable payment method

Consider how long the method takes.

6. Allow for weekends and bank holidays

Do not assume a transfer made on a Friday will arrive immediately.

7. Keep evidence of payment

Retain the confirmation, transaction record and relevant correspondence with your accounting records. This small checklist can prevent many avoidable payment problems.

Conclusion: Choose the Payment Method Before the Deadline Becomes Urgent

Paying Corporation Tax is straightforward when the company plans ahead. The main choices are online bank payments, Faster Payments, CHAPS, card payments, Direct Debit and Bacs. The important difference between them is how quickly the payment reaches HMRC.

For most businesses, the safest approach is to confirm the Corporation Tax liability and deadline early, obtain the correct 17-character payment reference, select a payment method with enough processing time and retain evidence that the payment was made. Do not leave a Corporation Tax payment until the final afternoon simply because the money is already sitting in the company's bank account. A payment method can be just as important as the payment itself.

For founders, directors and international business owners, a reliable tax calendar and clear responsibility for HMRC payments can prevent small administrative mistakes from becoming expensive compliance problems.
