Under Section 194-IB of the Income-tax Act, 1961, TDS on rent by specified individuals/HUFs is to be deducted at the prescribed rate (currently 2%) and reported through Form 26QC. If the tenant erroneously deducts and deposits tax at a higher rate (e.g., 10%), the amount so deposited is still treated as tax deducted at source on behalf of the deductee (landlord) under Section 199 read with Rule 37BA. Consequently, credit should flow to the landlord's Form 26AS/AIS to the extent of the tax actually deposited, subject to proper PAN reporting and successful processing of the statement. The Act does not restrict credit to the "correct rate"; rather, it links credit to actual tax deposited and matched with the deductee's PAN.
However, administrative mismatches may arise if the filing is inconsistent with the statutory rate or validation rules, in which case rectification/correction of Form 26QC by the tenant may be required. The absence of a strict rate validation field in Form 26QC is procedural in nature and does not override the substantive provisions of Section 199; excess deduction, if any, is ordinarily claimable as credit/refund by the landlord in the return of income.
For return purposes, such TDS is not a separate "category of income" but a tax credit linked to rental income chargeable under the head "Income from House Property".
