Assessee in returns of income filed had not shown any rental income of his property.  The AO estimated the estimated annual letting value of property at Rs. 12 lacs for assessment year 2011-12 and added an annual enhancement of 10 per cent on same for subsequent years. Commissioner (Appeals) upheld order of Assessing Officer.  On appeal the Tribunal held that the Assessing Officer had not based estimate on any reasonable working in determining annual letting value. It was also noted that no description of property as to area and market rates prevalent for rents had been brought on record. Since annual value determined was devoid of any rational endorsement, appeals filed by assessee deserved to be allowed.  (AY. 2011-12 to 2013-14)
