§ Mr. Burstow
To ask the Chancellor of the Exchequer how many child tax credit calculations have resulted in underpayment as a result of computer problems which lead to an incorrect assessment of income; how many people have been affected by such errors; how much has been underpaid as a result; and what steps have been taken to(a) explain and (b) apologise to those affected. 
§ Dawn Primarolo
The Inland Revenue is not aware of any such issues causing underpayment of child tax credit. The income element of the entitlement calculation is based on figures supplied by the claimant rather than an assessment by the Inland Revenue. The Inland Revenue will be pleased to look into any individual cases where people consider that they have been underpaid tax credits in such circumstances.
