Update (Feb 2026): With the 8th Pay Commission discussions heating up post-Budget, Central Government employees are now focusing on the potential Arrears Calculation. Since the commission’s implementation date is expected to be January 1, 2026 (retrospective), any delay in the final notification will result in a substantial accumulation of arrears.
This guide provides the Official Formula for calculating arrears, a Level-wise breakdown (Level 1 to 18), and critical information on how to save tax on this lump-sum payment using Form 10E.
• Expected Date: Jan 1, 2026 (Retrospective).
• Payment Date: Likely 2027 (Lump Sum).
• Est. Amount (Level 1): ₹85,000+ (for 12 Months).
• Tax Relief: Available under Section 89(1).
The Arrears Formula (How to Calculate)
Arrears are simply the difference between what you should have been paid (New Salary) and what you were actually paid (Old Salary) during the delay period.
Monthly Arrears = (New Basic + New DA) – (Old Basic + Old DA)
Total Arrears = Monthly Arrears × Number of Delayed Months
The “Zero DA” Factor:
When the 8th Pay Commission is implemented, the Dearness Allowance (DA) will likely be reset to 0% (or a very low percentage). This means while your Basic Pay will jump significantly (approx 1.96x), the DA component will drop. The arrears are calculated on the Net Difference.
Level-Wise Arrears Table (Projected)
Below is the estimated arrears chart for a 12-Month Delay (Jan 2026 to Dec 2026). This assumes a conservative Fitment Factor of 1.96.
| Pay Level | Old Basic (Entry) | New Basic (Est) | Monthly Difference | Total Arrears (1 Year) |
|---|---|---|---|---|
| Level 1 (MTS) | ₹18,000 | ₹35,280 | ~ ₹7,000 | ₹84,000+ |
| Level 2 (LDC) | ₹19,900 | ₹39,000 | ~ ₹8,200 | ₹98,400+ |
| Level 3 (Constable) | ₹21,700 | ₹42,500 | ~ ₹9,000 | ₹1.08 Lakh+ |
| Level 6 (JE/SI) | ₹35,400 | ₹69,400 | ~ ₹14,500 | ₹1.74 Lakh+ |
| Level 7 (Inspector) | ₹44,900 | ₹88,000 | ~ ₹18,000 | ₹2.16 Lakh+ |
| Level 10 (Sr. AO) | ₹56,100 | ₹1,10,000 | ~ ₹24,000 | ₹2.88 Lakh+ |

Tax Warning: Don’t Lose 30% to TDS
Receiving ₹2 Lakhs as a lump sum arrears in one month will spike your income, potentially pushing you into the 30% tax slab. However, the Income Tax Act provides relief.
Section 89(1) Relief (Mandatory)
You can claim relief under Section 89(1), which allows you to spread the tax liability of the arrears over the years they actually belong to (e.g., 2026), rather than paying tax on the entire amount in the year of receipt (e.g., 2027).
Requirement: You MUST file Form 10E on the Income Tax Portal before filing your ITR. If Form 10E is not filed, the Income Tax Department will send a notice for the unpaid tax.
Will Allowances Get Arrears?
This is a common confusion. The rules for arrears differ for Basic Pay vs Allowances:
- Basic Pay & DA: Arrears are Paid (Retrospective effect).
- HRA (House Rent Allowance): Arrears are NOT Paid. HRA rates are usually revised only from the date of the official notification (Prospectively).
- Transport Allowance (TPTA): Adjusted based on the new DA rate. Since DA drops to 0%, TPTA arrears are often negligible or nil.
Will I get interest on late arrears payment?
No. The government generally does not pay interest on Pay Commission arrears, even if the payment is delayed by 18-24 months.
Is NPS deducted from arrears?
Yes. 10% of the arrear amount (Basic + DA component) is mandatorily deducted for the National Pension System (NPS). The government will also contribute its 14% share for the arrears period.
Can I refuse arrears to avoid tax?
No. Arrears are part of your salary income. You cannot refuse them, but you can legally reduce the tax burden by filing Form 10E under Section 89(1).
हिंदी सारांश
8वें वेतन आयोग के एरियर (Arrears) की गणना के लिए फार्मूला तैयार है। यदि आयोग 1 जनवरी 2026 से लागू होता है और नोटिफिकेशन 2027 में आता है, तो कर्मचारियों को 12 से 18 महीने का एरियर मिलेगा। लेवल-1 (MTS) कर्मचारी को लगभग 84,000 रुपये और लेवल-7 (इंस्पेक्टर) को 2 लाख रुपये से अधिक का एरियर मिल सकता है। एरियर पर टैक्स बचाने के लिए Form 10E भरना अनिवार्य होगा। ध्यान दें कि HRA पर एरियर नहीं मिलता है।
