Explained in this library

What section 23 does, in plain English, before you read what the courts made of it.

House property: annual value and what you can deduct

How is rental income taxed, and what if the flat is empty or lying unsold?

The default regime takes the interest on your own house, not the thirty per cent on a let one

I am in the default regime. Do I still get the thirty per cent standard deduction, and the interest on a property that is let out?

The flat was empty all year: when s.23(1)(c) actually helps

My property was vacant for the whole year. Can the annual value be taken as nil?

When the officer says your rent is too low: how annual value is fixed

The AO thinks the rent I declared is understated. How is the annual value of a let out property actually determined?
