Thanks everybody for sharing further details.
Based on the circular and my first post I have a little querry about the amount of monthly rent (Rs.15000 per month as mentioned in my first post).
The relevant para under section 10(13A) reads
"Further if annual rent paid by the employee exceeds Rs 1,80,000 per annum, it is mandatory for the employee to report PAN of the landlord to the employer. In case the landlord does not have a PAN, a declaration to this effect from the landlord along with the name and address of the landlord should be filed by the employee. "

Now suppose rent structure for the year is as follows
April to July -----13500*4 = 54000 (Landlord 1)
Aug to March--- 16000*8 =128000 (Landlord 2)
Thus total rent paid during the year is Rs.182000.
1)The rent per month doesnot exceed Rs.15000 (April-July)
2)Total annual rent exceeds Rs.180000
Now the question is -- does the employee needs to report PAN details of both the landlords?
Also clarify if there is any mistake in interpretation.
