Pension contribution deduction limits govern employer and individual deductions, with deferred taxation when withdrawn or converted to annuity. Deductions are allowed for employer and assessee contributions to a Central Government-notified pension scheme subject to prescribed limits based on the employer's identity and special treatment for assessees chargeable under section 202(1). Individual contributions are deductible up to a fixed monetary ceiling, including contributions to a minor's account within the same cap, but amounts already claimed under another specified provision are excluded. Amounts previously deducted and later received on scheme closure, opting out, or as annuity or on certain retirements are deemed income of the year of receipt and taxed, with limited exceptions and a non receipt rule where the amount is used to purchase an annuity or transferred to pool corpus.
