Mf- tax on distributable income?

Yes, when paid to unit holders; as DDT liability is over asset company. For equity oriented funds it is nil, so no tax deducted before the distribution.

DDT is not paid incase of Money mkt & liquid schemes/ Debt Schemes?

It is mentioned "Tax on distributed income (payable by the scheme) rates , Money market and Liquid schemes , 25% + 12% Surcharge + 3% Cess= 28.84%"

Yes, The DDT is to be paid by asset company as applicable to the debt fund, but for unit holders it is taxfree (whatever be the scheme).
