Form 26qb late payment notice

Dear Experts,

I recieved a late payement charge for the 1% TDS for property that I have made. Given below are the details.

Date of Deduction/Credit as Per 26QB : 29-May-2015

Due Date of Deduction : 29-May-2015

Date of Deduction as Per 26QB : 03-Jun-2015

TDS Deductable : 7575

Perios of Delay : 2 Months

Interest of Late deduction : 2 months (Date of Deduction as per 26QB - Due Date of deduction)

Late payment on deduction : 7575*2*1%

Why os the late payment charge levied since I have made TDS deposit within 7 days of the from the end of the month of deduction.

Please advise.

Thanks,

Jaya
