Once your figures are in, our system prepares a draft of your accounts and CT600 and your accountant reviews it in full. We aim to have everything ready for you within two working days of receiving what we need. You review it, we answer any questions, and we only file once you've approved — with confirmation sent when both submissions are complete.
No. AI handles the preparation work — categorising, reconciling and drafting — which is where the time savings come from. A qualified accountant then reviews every figure and takes responsibility for what is filed. Nothing is submitted without human sign-off and your approval.
The CT600 is the Corporation Tax return HMRC requires from all active companies. It covers your tax calculation, accounts and supporting computations — all included in your fee.
If your first accounting period runs longer than 12 months, HMRC requires two returns — one covering the first 12 months and a second covering the remainder. Where this applies, both are included in your package.
Upload them directly in the portal, or email them to us — whichever is easier.
Log in to your account once we've told you your filings are ready to review. After submission you'll receive a confirmation email and can download everything for your records at any time.

Usually, yes. Tell us your deadline when you sign up and we'll prioritise your filing. The sooner your documents reach us, the sooner we can submit.
