Arrears are taxed in the year you receive them. The income-tax law gives relief when pay for earlier years arrives late; claim it before you file your return.

This is an estimate. The 8th Pay Commission has not given its report yet, so the fitment factor, pay matrix and allowances are not decided.

About arrears

How are 8th Pay Commission arrears worked out?

For every month from the effective date until the new pay starts, we add the difference between new pay + DA and old pay + DA. Annual increments and DA changes every six months are counted.

Will HRA and TA arrears be paid?

At the 7th CPC, arrears covered basic pay and DA only; the new allowances started on 1 July 2017. What happens at the 8th CPC is for the Government to decide, so it is an option here.

How are arrears taxed?

Arrears count as income in the year you receive them. The income-tax law gives relief so you are not taxed more because pay for earlier years arrived late; claim it before you file your return.
