Non payment of tds by employer

the amount of TDS that would have been paid by your employer but remaining unpaid will be adjusted together with interets u/s 234B&C against the refund  payable to you.  If there's additional demand then you would be required to pay the same.

Query 1 - You will not be required to pay the tax deducted by employer as per section 205 " Where tax is deductible at the source under sections 192, the assessee shall not be called upon to pay tax himself to the extent to which tax has been deducted from that income."

Query 2 - Yes the refund will be paid to you after adjustment of interest u/s 234B & 234C.

Query 3 - You just need to pay interest u/s 234 B & C and if after adjusting the aforesaid interest any refund is due, you will be paid the same.
