What this service covers.

The CT600 must agree with the statutory accounts and the tax computation. Adjustments for capital allowances, disallowable expenses and losses are where errors usually appear.

We prepare the computation and return, review them before filing and set out the payment dates and any reliefs claimed.

FAQ

Corporation Tax (CT600) questions

When is Corporation Tax due?

The return is due 12 months after the accounting period end; tax is usually payable nine months and one day after the period end.

Can you file an amended return?

Yes. We can review and amend a previously filed return where an error is identified.

Are there penalties for late filing?

Yes. HMRC applies fixed and tax-based penalties, so early preparation is safer.
