Dear Sir, I am slightly confused about filing Income tax return for the Assessment year 2014-15. My Wife has a Gross salary of Rs 7.18 lacs. After showing showing a deduction of Rs 0.87 lacs towards interest paid on housing loan, the Taxable limit comes to Rs 6.32 lacs. She has donated a sum of Rs 1.25 lacs to a Charitable institution for which a deduction of 50% from the total contribution is available. I desire to know what should be the maximum donation amount which is available for exemption? What would be the amount that can be claimed as exemption for filing the ITR? Whether ITR1 can be used for filing the Return? She is haveing income only from salary. KIndly oblige me with your reply so that I can file her return in time.Are any original documents to be attached to ITR?
