In a bid to boost housing sales, Finance Minister Nirmala Sitharaman on Thursday announced an increase in the permitted differential between the circle rale and the agreement value of housing units to 20 per cent from the current mandated limit of 10 per cent till June 30.

The increase in differential will be applicable in residential units of value up to Rs two crore. It will help in reducing the tax liability as tax will be applicable on lower value of residential units.
