TDS certificate requirement: Form 16E must state transaction details, tax deposited particulars and a signed verification. Form 16E is the tax deduction certificate to be issued by a deductor for tax deducted at source, identifying deductor and deductee, recording PAN/Aadhaar, financial year, and a transaction summary with unique acknowledgement numbers, dates, amounts and tax deducted. It requires separate particulars of tax deposited to government-amounts attributable to the deductee, Challan Identification Number, BSR code, bank branch, deposit date and challan serial number-and a signed verification by the person responsible certifying accuracy based on books, documents and challans.
