What is the difference between inter-source and inter-head adjustment?
A taxpayer who has incurred a loss from a source under a particular head of income is allowed to adjust the loss against income from any other source falling under the same head. This is called inter-source adjustment. After this, the taxpayer can make inter-head adjustment, where the loss incurred under one head of income can be adjusted against income under another head. For example, Adjustment of loss from business A against profit from business B is inter-source, while adjustment of loss under the head of house property against salary income is inter-head.
