Consequences for filing itr 4 instead of itr 4s

hi,

my income in f.y. 11-12 is as follows

Gross receipt - rs. 187200/-

expenses claimed rs. 13867/-

depreciation claimed rs. 4624.

Income from business rs. 168709/-

salary income rs. 30000.

total income rs. 198709/-.

I have paid tax rs. 1927/-.

However, I have filed return in ITR 4 instead of ITR 4S u/s 44 AD. Data feeded in the colum under "regular books of accounts are not maintained".

Sir, I want to know the consequences for not filing return in ITR 4s and filing return in ITR 4.
