8th CPC Arrears & Income Tax — Section 89 Relief Explained
When the 8th CPC pays out retroactively from January 2026, the arrears land as a lump sum in the year you actually receive them — and income tax treats them as income of that year, potentially pushing you into a higher slab. Section 89(1) of the Income Tax Act exists precisely for this: it lets you claim relief so arrears are effectively taxed as if received in the years they belong to.
The mechanics: compute tax with arrears included, then compute tax as if the arrears had been spread back to their original years — the difference is your relief. The mandatory step most people miss: Form 10E must be filed before filing your ITR to claim Section 89 relief. Without it the claim gets rejected at processing even though you were entitled.
Arrears also hit in the same year for employees near retirement — combining arrears with gratuity/leave encashment can compress multiple years of income into one slab.
Example
Arrears ₹2,00,000 received FY 2026-27 on top of ₹12L salary: without relief taxed at 30% ≈ ₹60,000 tax on arrears. With Section 89 spread over two earlier years at 20% slabs, tax ≈ ₹40,000 — relief ~₹20,000. Requires Form 10E.
