Tds 194I

If the landlord has proof that the tenant has deducted the TDS from his rent, in that case appeal can be filed by him. 

There are various judgements which state that credit cant be denied if its not deposited by the deductor. But for proving this there has to be some proof that TDS is deducted. 

You can apply for 154 and also file an appeal. Since, i feel this is a debeatable issue and 154 is for mistake which is apperant from records.
