Form No. 132: TDS certificate (Earlier Form 16B/16C/16D/16E )

Form No. 132 is a TDS certificate issued for tax deducted at source on specific transactions involving payment of rent, transfer of immovable property, technical services, or transfer of Virtual Digital Assets (VDA). It merges Forms 16B, 16C, 16D & 16E into one.

It must be issued by the deductor after depositing TDS and serves as proof for the deductee to claim TDS credit while filing ITR. It is mandatory, generated via TRACES, and must be issued within 15 days of filing the challan-cum-statement (Form 141).

Form No. 93/94/95/96: PAN Application (Earlier Form 49A/49AA)

These forms are used for allotment of Permanent Account Number (PAN):

Form 93: Individual (Citizen of India)

Form 94: Non-Individual Indian Entities

Form 95: Individual (Non-Citizen)

Form 96: Foreign Entities

PAN is a unique identifier required for tax filing and financial transactions. Applications can be filed online or through authorised centres with proof of identity, address, and date of birth/incorporation.

Form No. 39: Relief under Section 157(1) (Earlier Form 10E)

Form 39 is used to claim tax relief on additional salary (arrears/advance), gratuity, retrenchment compensation, or commutation of pension.

It helps reduce higher tax liability arising from lump-sum receipts. The form must be filed online before claiming relief in the ITR and is mandatory if such relief is claimed.

Form No. 124: Employee Declaration for Deductions (Earlier Form 12BB)

Form 124 is submitted by employees to employers to claim deductions and exemptions such as HRA, LTA, housing loan interest, and investments.

It enables the employer to compute the correct TDS on salary. Supporting documents, like a rent agreement or investment proof, must be provided.

Form No. 168: Annual Information Statement (AIS) (Earlier Form 26AS)

AIS is a detailed statement of a taxpayer’s financial transactions reported to the Income-tax Department, including TDS, investments, taxes paid, and more.

It also includes TIS (Taxpayer Information Summary), a simplified summary used while filing ITR. Reviewing AIS helps avoid errors and tax notices.

Form No. 121: Declaration for No TDS (Earlier Form 15G/15H)

Form 121 is a declaration to avoid TDS where the taxpayer’s total tax liability is nil. It replaces Forms 15G and 15H into a single form.

It must be submitted to the payer before income is credited and is applicable to incomes like interest, dividends, rent, etc. The form improves compliance and reduces refund hassles.
