Taxable income in itr

My Client's Salary Income as per Form 16 provided by Employer is Rs. 7,25,000/-, whereas, Salary Income as per Form 26AS is Rs. 6,40,000/-. If I take Salary Income of Rs. 7,25,000/- as per Form 16, then additional Tax of Rs. 4,000/- is required to be paid, whereas if I take Salary Income as per Form 16 i.e. Rs. 6,40,000/-, then a refund of Rs. 12,000/- is receivable. Other Income includes Bank Interest which is negligible.Can you kindly suggest which income I should take? This is the first year I'm taking up such an assignment. Thank You.
