HMRC Corporation Tax Compliance Support

What HMRC corporation tax compliance support covers

This service is designed to take the pressure out of corporation tax and reduce the risk of errors, missed deadlines, and HMRC follow-up.

• Confirming your accounting period and filing deadline
• Reviewing your profit figure and key tax adjustments
• Checking common corporation tax areas (allowable expenses, director costs, benefit in kind considerations, capital allowances)
• Preparing the corporation tax computation and CT600 return
• Ensuring the right supporting iXBRL attachments are included for online filing
• Sharing a clear summary of the liability and payment deadline
• Filing the return with your approval and keeping submission evidence
• Support with amendments if something changes after filing

When this service is the right fit

This is most relevant if you run a limited company and want corporation tax handled properly without having to interpret HMRC guidance yourself.

Common situations include:

• Your first corporation tax return and you want it set up correctly
• Your bookkeeping is up to date, but you are unsure what is tax deductible
• You have dividends, director’s loan activity, or irregular business expenses
• Your results changed significantly and you want to avoid surprises at year end
• You want to reduce the risk of penalties by meeting filing and payment dates

How the process works

You provide access to your accounting records and any key documents for the period. The return is prepared, checked, and then sent to you with a plain-English summary of what is being filed and why.

Once you approve, the CT600 and attachments are submitted to HMRC. You receive confirmation of submission and guidance on what needs paying and when.

What happens after filing

You get a clear record of what was filed and the figures used, so you can evidence your position if HMRC asks questions later. If HMRC raises a query, you can get support responding with the right documents and explanations. You can also use the results to plan ahead for the next period, with practical steps to keep corporation tax predictable.
