Regarding Income Tax Deduction Notice - if employee doesn't submit investment declaration form

Please help me in drafting notice regarding income tax deduction if employee doesn't submit investment declaration form. Need it urgently to send mail and put it on notice board.

Put up a draft and members will amend it and make it perfect.
Pl do not expect members to first draft notices and then you will correct it.

Dear Employees,
Please submit your investment details to Accounts Dept before 31st Jan 2018 for tax deduction purpose.
Mr Nathrao please make necessary changes in the draft

Dear employees,
The current Financial Year 2017-18 A/Y 2018-19 ends on 31 Mar 2018.
IT calculations/TDS deductions were made on the basis of investment details declared during the year.
Kindly submit proof of investment by 31 Jan 2018 for verification purposes and computation of taxes.
In case proof of investment is not submitted by due date, necessary reversal of tax deductions will have to be made for compliance with tax laws.
Kindly note.

Dear Nathrao,
Thank you so much for your quick response.
