Income tax - employer liability for tds

Regards to all peers

I have two queries regarding TDS.

Q 1. Is the employer is liable or is it obligation of employer to get the investment declaration form (prospective investments) from employees at the begining of FY. If yes then where it is mentioned i.e. in ACT, CIRCULAR or NOTIFICATION?

Q 2. If employer deduct TDS on the basis of above mentioned prospective investment declaration, then if at the end of the year declarations differs from actual investments made, there will be definite chances of TDS short / excess deducted in earlier months. Then the question arises that is employer liable to pay the interest on TDS short deducted for earlier months?  If yes then where it is mentioned i.e. in ACT, CIRCULAR or NOTIFICATION? (we have so far received such notices from IT department)

Hoping to get appropriate answers for above mentioned queries.

Thanks & Regards
