FYI
If the person responsible for deducting or depositing the tax at source, does not pay or deposit the TDS then Interest u/s.201(1A) @ 12% p.a. from the date on which the tax was deductible to the date on which such tax is actually paid will be levied on the amount of such tax.
And now can understand very well
Penalty u/s.271C is leviable if the assessee fails to deduct the tax at source within the prescribed time. The penalty leviable is equal to the amount of tax the deductor failed to deduct.
PROSECUTION U/S.276B
If the deductor fails to deposit the tax deducted by him at source, he shall be punishable with rigorous imprisonment for a term from three months to seven years along with fine.
