Short answer
Arrears are the difference between the pay you should have received from the effective date and what you were actually paid. For the 8th Pay Commission, neither the effective date nor the payment date is fixed, so any figure is a scenario.

What is official about the date
The Government's press note of 28 October 2025 says that, going by the ten-year pattern, the effect of the 8th Pay Commission recommendations "would normally be expected from 01.01.2026". That is background reasoning, not an order. The Commission has 18 months from 3 November 2025 to report, which is about 3 May 2027. No effective date has been notified.
What happened in 2016
The 7th CPC reported on 19 November 2015 and recommended implementation from 1 January 2016. The revised pay rules were notified on 25 July 2016 and apply from 1 January 2016. The Department of Expenditure's order said the arrears of revised pay were to be paid in cash in one instalment with August 2016 salary, after adjusting GPF and NPS. Allowance rates were to be notified separately, and HRA at the new rates took effect from 1 July 2017.
Two lessons. First, retrospective pay is possible: the 2016 rules were notified seven months after the effective date and still counted from it. Second, arrears of pay and arrears of allowances were treated differently, which is why the calculator leaves HRA out by default.
(Unconfirmed) The statement that no allowance arrears were notified rests on one news report.The formula
Arrears are built month by month:
Monthly gap = (new basic + DA on new pay) − (basic + DA you actually drew)
Arrears = monthly gap × number of months from the effective date to the month before new pay starts.
The DA you drew changes over time, so the calculation uses 60% for January to June 2026 and 63% from July 2026 (Cabinet, 28 October 2026). Enter the rates on your own payslip if they differ.
A gap is never negative: a revised structure would not cut pay.
Worked numbers
At a test factor of 1.83, DA restarting at 0%, HRA excluded, DA of 60% on old pay for January to June 2026 and 63% from July 2026.
| First month paid at new rates | Months counted | Level 1 (basic ₹18,000), gap ₹4,200 then ₹3,660 | Level 10 (basic ₹56,100), gap ₹12,940 then ₹11,257 |
|---|---|---|---|
| July 2027 | 18 | ₹69,120 | ₹2,12,724 |
| January 2028 | 24 | ₹91,080 | ₹2,80,266 |
| February 2028 | 25 | ₹94,740 | ₹2,91,523 |
| July 2028 | 30 | ₹1,13,040 | ₹3,47,808 |
How the Level 10 gap arises: new basic ₹1,02,700 (₹56,100 × 1.83, rounded up) against ₹56,100 + ₹33,660 DA = ₹89,760 drawn in January to June 2026 (a gap of ₹12,940) and ₹56,100 + ₹35,343 DA = ₹91,443 from July 2026 (a gap of ₹11,257).
Change any assumption in the 8th Pay Commission arrears calculator.
What would change the figure
- Fitment factor. A higher factor raises the gap in proportion.
- DA on new pay. If DA does not restart at zero, the gap is larger.
- HRA arrears. If HRA is included from the effective date, the gap rises.
- Later start. Every extra month adds one more gap.
- Effective date. If it is later than 1 January 2026, fewer months count.
Tax on arrears
Arrears are taxed as salary in the year you receive them, which can push you into a higher slab. A relief mechanism spreads the tax as if the arrears had been received in the years they relate to. Under the Income-tax Act, 1961 that was Section 89(1) with Form 10E. Under the Income-tax Act, 2025 it is Section 157(1) with Rule 73 of the Income-tax Rules, 2026 and Form 39, applicable from Tax Year 2026-27, so arrears received from 1 April 2026 fall under Form 39. Confirm on the e-filing portal and ask your DDO.
What to do now
- Keep every payslip from January 2026 onward.
- Record your DA percentage and basic pay each month.
- Do not borrow against arrears that have not been announced.
- Watch the 8th Pay Commission tracker for an effective date.
