Commuted pension tax treatment: part exempt, part taxable; exemption reduced where gratuity is received.
Uncommuted pension is fully taxable as salary; commuted pension is partly exempt and partly taxable. Compute a notional full pension value from the commuted payment and apply an exemption fraction: if no gratuity is received, one half of the notional full pension value is exempt; if gratuity is received, one third is exempt. The remainder of the commuted payment is chargeable to tax as salary and must be added to taxable uncommuted pension to determine total taxable pension income.

Gratuity exemption: least of three test determines exempt portion for noncovered employers; excess gratuity is taxable.
Gratuity from a noncovered employer is exempt to the extent of the least of three amounts: the service based fraction computed from the average monthly salary (which includes basic pay, one month's dearness allowance, and average monthly commission), the statutory monetary ceiling, and the gratuity actually received; any excess over that exempt amount is taxable.

Gratuity exemption: part determined by 15 days salary times completed years, excess treated as taxable salary.
Gratuity exemption is determined by taking the least of: the product of 15 days' salary and completed years of service, the statutory ceiling, and the gratuity received. Completed years may be rounded to include qualifying months. The exempt portion is that least amount; any excess over the exempt amount is taxable as salary income in the assessment year.
