Set off of business loss

Business loss other than speculative business loss can be set off income from other sources (including interest income).But inter head adjustment is permissible only in the year in which loss has been incurred.In subsequent years,such unabsorbed business losses can be set off with income from business and profession only.

Yes you can set off business loss (but not speculation loss) against income from other sources., (during the same AY only)
