Paying your UK Corporation Tax on time is a legal obligation—but more than that, it’s a key part of maintaining your business’s financial health. For many UK small businesses, managing tax responsibilities can feel overwhelming, especially when juggling deadlines, allowances, and compliance requirements. That’s where professional accounting services in UK come in.
Working with an accountant doesn’t just reduce stress—it can also optimise your tax position, improve your cash flow, and shield your company from costly penalties.
Here’s how an experienced accountant can support your business with UK Corporation Tax payments.
Accountants stay informed about current Corporation Tax rules, rates, and reliefs. This is vital for staying compliant with HMRC’s expectations.
Corporation Tax rates vary: small profits are taxed at 19%, while the main rate is 25%.
Marginal Relief applies to profits between £50,000 and £250,000, requiring accurate calculation.
Accountants can help you avoid common errors that may lead to penalties or overpayments.
In short, they make sure that all figures are correct and that nothing is missed.
Filing deadlines and payment due dates are strict. Missing them leads to financial penalties and interest charges.
Corporation Tax must be paid within 9 months and 1 day of your accounting period’s end.
The tax return must be filed within 12 months of the end of the accounting period.
Interest on late payments is currently 8.25% per annum, charged daily by HMRC.
Fixed penalties start at £100 and increase over time, with additional surcharges for continued non-compliance.
An accountant keeps you ahead of deadlines, helping you avoid late fees and added stress.
Tax isn’t just about paying—it’s also about planning. Accountants can help reduce your liability legally through strategic tax planning.
They identify allowable expenses and business deductions.
They help you make use of capital allowances.
They calculate and apply Marginal Relief correctly.
They spot tax-saving opportunities that might not be obvious.
With a strategic approach, you can improve cash flow and keep more money in your business.

They also help manage transitions such as restructuring, mergers, or changes in ownership.
Expert guidance in these moments can prevent compliance issues later on.

They advise on best practices for setting aside funds throughout the year.
If necessary, they can help you negotiate a Time to Pay arrangement with HMRC.
