What is Corporation Tax?

You must complete a Corporation Tax Return and pay tax on profits from doing business if you are registered as:

  • a limited company
  • any foreign company with a UK branch or office
  • a club, co-operative or other unincorporated association, e.g. a community group or sports club

The deadline to submit your Corporation Tax Return and pay your tax bill is 9 months and 1 day after the end of the company’s financial year.

Unfortunately, not submitting on time, could result in considerable penalties and interest being accrued by HMRC. This is why it’s so important to put arrangements in place early on to ensure everything is completed on time.

Another huge benefit to being organised with your tax affairs is that you will know how much tax is due in advance with a good amount of time to pay your balance to HMRC.

Benefits of choosing us for your Tax Returns

A Corporation Tax Return can be a very complex submission, so it is almost always better to seek advice from a professional than attempting to complete your own Corporation Tax Return.

Some of the benefits of using Accounting Wise to handle your tax affairs are:

Peace of mind
By using professionals you know that your tax calculations will be correct and accurate.

Corporation Tax Return Investigations
You are less likely to be investigated by HMRC if you use an advisor, as HMRC have ways of knowing if figures submitted on a return are likely to be incorrect. This is a common trigger for a tax investigation.

Save time
In most cases it will take you a lot longer to complete your own self assessment tax return than it would for an advisor. This time could be better spent running your business.

Claiming everything you’re entitled to claim
It is a very rare occasion that we take on a new client and are not able to find areas to reduce the tax owed. This is usually in the form of under declared expenses. Most business owners are not aware of all the different types of expenditure that can be claimed and how best to claim them, which is where we come in.

Essential FAQs for Corporation Tax Returns Services

0330 113 8442 Request Call Back

A Corporation Tax Return (CT600) is a document submitted to HMRC by limited companies, detailing their income, expenses, and calculated Corporation Tax due for an accounting period.

You must file your Corporation Tax Return within 12 months of the end of your company’s accounting period – but the tax payment is usually due 9 months and 1 day after the period ends.

HMRC charges automatic penalties for late filing, starting at £100 and increasing the longer the return remains outstanding. Interest may also apply to late payments.

Yes, most active UK limited companies must file a return – even if they have made no profit or owe no tax. Dormant companies generally do not need to file, unless asked by HMRC.

Absolutely. We’ll prepare and file your CT600 accurately and on time, ensuring you claim all allowable expenses and reliefs to minimise your tax liability.

We’ll need your company accounts, details of income and expenses, any capital allowances, and information on any previous losses or tax reliefs. Don’t worry – we’ll guide you through every step.

Yes, it’s possible to file it yourself through HMRC’s system, but many business owners prefer using an accountant to ensure accuracy, avoid penalties, and make the most of tax reliefs.

Our pricing is competitive and tailored to the complexity of your business. Contact us for a free quote or view our accounting packages.

Capital allowances let you deduct the cost of certain business assets – like equipment, machinery, or vehicles from your taxable profits.
