Common questions

Corporation Tax FAQs

When is corporation tax due?

For many UK companies, Corporation Tax is payable nine months and one day after the end of the accounting period. Different payment rules can apply to larger companies, so it is important to check the requirements for your business.

When does a company need to file a CT600 return?

A company generally needs to file its Corporation Tax return with HMRC within 12 months of the end of its accounting period. The filing deadline is different from the Corporation Tax payment deadline.

What is included in a corporation tax return?

A CT600 return reports the company profits and relevant tax adjustments used to calculate its Corporation Tax liability. It is normally prepared alongside the company tax computation and supporting accounts information.

Can you help reduce my company corporation tax bill?

We can review your company financial position and discuss relevant tax reliefs, allowances and planning opportunities. The options available depend on your company activities and circumstances.

Can you prepare corporation tax returns online?

Yes. Digital Tax provides online corporation tax support across the UK. You can share your company accounts and financial records digitally and communicate with us without needing to visit an office.

Does corporation tax include annual company accounts?

Corporation Tax returns and annual company accounts are separate requirements. They are closely connected because the company accounts provide the starting point for calculating taxable profits. We can coordinate both services where they are included in your agreed package.
