Documents

What we need from you

Send these through the portal and we can start on the computation the same week.

  1. Last year's statutory accounts and tax return, however they were filed
  2. Access to your bookkeeping software, or the records we can build the books from
  3. Bank and credit card statements for every business account
  4. Payroll records, P60s and P11Ds, and any CIS deductions taken or suffered
  5. Asset purchases and finance agreements, for the capital allowances claim

Missing one of them? Send what you have. We will tell you what is still outstanding well before the deadline, not the week it falls due.

Frequently asked

Common questions

The six we are asked before almost every UK filing, company and director alike.

There are two dates and they are not the same one, which is where most companies come unstuck. The payment is due nine months and one day after the end of the accounting period. The CT600 return is due twelve months after it. So the money leaves three months before the return goes in, so we give you the figure at the nine-month mark rather than at the deadline for filing.

Get it filed before HMRC asks twice

One team from the digital records to the submission receipt: the computation, the reliefs, the sign-off you actually see, and whoever answers HMRC if it writes. No handing you a PDF in January and going quiet.
