Missing a corporation tax deadline can feel overwhelming. For many business owners, a large tax bill arrives at the wrong time—cash flow is tight, customers are paying late, or unexpected costs have drained reserves. If you’re struggling to pay your corporation tax bill, the most important thing to know is this: you still have options, and acting early makes a significant difference.
This guide explains what corporation tax is, what happens if you can’t pay on time, how HMRC payment plans work, and when alternative funding—such as a corporation tax loan—may be the right solution.
Key Takeaways
Corporation tax must be paid within strict deadlines, but missing one does not mean the end of your business
HMRC offers a Time to Pay arrangement that allows you to spread the cost
Acting early reduces penalties, interest, and enforcement risk
Some businesses use external finance to settle tax bills immediately
Specialist lenders can help when HMRC payment plans are not approved
What Is Corporation Tax?
Corporation tax is a tax paid on a company’s profits. Once your business has deducted operating costs—such as wages, rent, utilities, supplier payments, and other expenses—any remaining profit is subject to corporation tax.
This tax contributes to funding public services such as healthcare, infrastructure, education, and transport. For limited companies, it is a legal obligation and must be paid in full, even during difficult trading periods.
Who Pays Corporation Tax?
Corporation tax is typically paid by:
Limited companies registered with Companies House
Some clubs, societies, and associations
Foreign companies with a permanent business presence
Company directors are responsible for ensuring corporation tax is calculated correctly and paid on time. Sole traders and partnerships do not pay corporation tax; instead, they pay income tax through self assessment.
New companies must register for corporation tax within three months of starting trading, even if they have not yet made a profit.
When Is Corporation Tax Due—and What Happens If You Don’t Pay?
Corporation tax is usually due nine months and one day after the end of your accounting period.
For example:
If your accounting year ends on 31 March, your corporation tax payment is due by 1 January the following year.
If you miss this deadline, HMRC will automatically:
Charge late payment interest
Add penalties if the delay continues
Escalate recovery action if no contact is made
Interest is charged at the Bank of England base rate plus an additional percentage, which increases the longer the balance remains unpaid. This can quickly turn a manageable tax bill into a much larger financial burden.
First Steps If You Can’t Pay: Don’t Ignore the Problem
One of the biggest mistakes businesses make is avoiding HMRC. Silence is often interpreted as unwillingness to pay rather than inability to pay.
HMRC is generally more flexible with businesses that:
Make contact early
Are transparent about their finances
Show a genuine intention to settle the debt
Taking action immediately improves your chances of securing a manageable solution.
Contact HMRC to Discuss a Time to Pay Arrangement
If you cannot pay your corporation tax in full, HMRC may offer a Time to Pay arrangement. This is a formal payment plan that allows you to spread the tax bill over monthly instalments.
To apply, you will need to explain:
Why you cannot pay the bill in full
How much you can realistically afford each month
Whether the financial difficulty is temporary
HMRC will review your situation and decide whether a payment plan is appropriate.
Who Qualifies for an HMRC Payment Plan?
While approval is not guaranteed, businesses are more likely to qualify if they:
Have a viable business model
Are experiencing short-term cash flow issues
Have a history of compliance
Can demonstrate affordability
HMRC will review your income, expenses, existing debts, and projected cash flow. Accuracy and honesty are essential—incorrect information can result in rejection or future enforcement action.
If a Time to Pay request is declined, alternative funding may still be available.
What You’ll Need Before Speaking to HMRC
Preparing in advance can make the process smoother. HMRC will usually ask for:
Your corporation tax reference number
The total amount owed
Recent bank statements
Profit and loss figures
Details of other outstanding liabilities
Having this information ready demonstrates professionalism and increases your credibility during negotiations.
What Does a Typical Payment Plan Look Like?
Most Time to Pay arrangements last between six and twelve months, although longer terms may be considered in some cases. Payments are usually made monthly by direct debit.
Interest may still apply, but this is often far more affordable than ongoing penalties or enforcement action.
Can You Use a Loan to Pay Corporation Tax?
Yes. Many businesses choose to use a corporation tax loan to settle their HMRC bill immediately.
This approach can:
Stop interest and penalties from accruing
Protect cash flow
Avoid HMRC enforcement action
Provide predictable monthly repayments
Unlike HMRC payment plans, specialist lenders can sometimes offer longer repayment terms and faster approvals, particularly when timing is critical.
FAQs
Can HMRC reject my payment plan request?
Yes. If this happens, you can request a review or explore alternative funding solutions such as a corporation tax loan.
Will a Time to Pay arrangement affect my credit rating?
No. HMRC payment plans are not reported to credit agencies.
How quickly should I contact HMRC if I can’t pay?
Immediately. The earlier you act, the more options you are likely to have.

Struggling to pay corporation tax is more common than many business owners realise. The key is not avoidance, but decisive action. Whether through an HMRC payment plan or structured finance, there are ways to manage your tax obligations without placing your business at risk.
