Since 2004, various changes to tax and benefit rules have made it necessary to update and in some cases revise the imputations. We have also taken the opportunity presented by our recent review of the tax and benefit system to make some further refinements to the imputation model. The purpose of this technical paper is to detail the methods for estimating taxes and benefits (and hence disposable income), highlighting the changes that have been made in Release 7.0 and providing indicative information of the effects of these changes on disposable income estimates provided in the data made available to users.
