COTAX Manual

Repayments / reallocations: non automatic reallocations: surrender COTAX repayment to COTAX

It is important that you prevent COTAX from automatically processing an overpayment if a company gives notice of surrender of all or part of it under S963 CTA 2010 or the extension under Regulation 9 of the CT Instalment Payments Regulation 1998.


Treat the recipient company as having paid any interest under S87A TMA 1970 that the surrendering company has paid in respect of the surrendered refund (S964(4)). COTAX cannot calculate this.

You must calculate it:

  • in accordance with Step 4 of the COM122043 Action Guide
  • enter it in the Related Interest field when you make the reallocation.

COTAX then makes a payment type posting of this amount against the interest liability of the recipient company.

Section 963/Reg 9 can only apply when all the relevant conditions are met, see COM122020 for more information. It is important that companies do not gain the interest advantages of Section 963/Reg 9 when they do not meet these conditions. See COM122070 for information about handling requests to set off a potential repayment due to one company against a liability of another company when Section 963/Reg 9 does not apply.

When the notice relates to an ‘early repayment’, deal with the surrender using Function REWD (Direct Reallocation Within COTAX) in the usual way. See COM125000 for more information.

Tax-related penalties

Following the reallocation of a S963/Reg 9 Surrender, COTAX calculates any tax-related payable by the recipient of the surrender automatically, taking account of the restriction in S964(3) CTA 2010.
