TDS Certificate is a certificate which is issued by the person who deducts TDS (deductor) to the deductee. Whenever TDS is deducted, the deductee must demand the TDS certificate which mentions the amount of TDS deducted from your payment.
The deductor can generate this certificate from TRACES after filing the TDS return. There are two types of TDS certificate:
Form 16- Is an annual TDS certificate issued to employees for TDS deducted from salary
Form 16A- Is a quarterly certificate issued in respect of all other types of payments
