What is Corporation Tax and who has to pay it?
Corporation Tax is a tax on the profits of limited companies and certain other organisations. If your business is registered as a limited company in the UK, you are legally required to pay Corporation Tax on your taxable profits.
When is Corporation Tax due?
For small companies corporation tax is usually due nine months and one day after the end of your accounting period. For example, if your company’s year-end is March 31, your payment is due by January 1 of the following year.
Do I need to file a Corporation Tax return if my company didn’t trade?
Yes, even dormant or non-trading companies must file a nil return with HMRC unless they’ve been officially marked as dormant by HMRC.
What is included in a Corporation Tax return?
A Corporation Tax return (CT600) includes your profit and loss summary, adjustments for tax purposes, capital allowances, and the final Corporation Tax calculation. It must be filed alongside your statutory accounts.
Can I claim expenses and allowances against Corporation Tax?
Yes, many legitimate business expenses can reduce your taxable profits, including staff costs, rent, software, travel, and capital allowances. We can help you claim everything you’re entitled to.
