If you are a central government employee or pensioner, your April or May 2026 salary likely included a chunky DA arrears credit — and many employees are confused about how the amount was calculated. The Union Cabinet approved a 2% DA hike (from 58% to 60%) effective 1 January 2026, but the official notification came only in mid-April 2026, which means employees received 4 months of arrears (January, February, March, April) as a lump sum.
This guide explains exactly how to calculate your DA arrears, with worked examples for every pay level, and shows you how to verify the amount credited to your account. By the end, you'll be able to check your salary slip with confidence.

Dearness Allowance (DA) is a cost-of-living adjustment paid to central government employees and Dearness Relief (DR) is paid to pensioners. The purpose is straightforward: as inflation rises, DA rises in step to protect the real purchasing power of government salaries and pensions.
DA is calculated as a percentage of Basic Pay (as per the 7th CPC Pay Matrix Level) and is revised twice every year:
- January cycle: Based on the 12-month average of AICPI-IW (All India Consumer Price Index for Industrial Workers) for the previous calendar year
- July cycle: Based on the 12-month average of AICPI-IW ending in June
Although DA is supposed to be effective from 1 January and 1 July, the formal notification typically comes 3–4 months later — and that lag is exactly why arrears get paid in a lump sum.
The Formula Behind DA
The Department of Expenditure uses this formula to compute DA percentage:
Where 115.76 is the base index (calendar year 2016 average, after the 7th CPC re-base).
For January 2026, the 12-month average of AICPI-IW (Jan–Dec 2025) was approximately 145.54, which gave a calculated DA of about 60.33% — rounded down to 60%.
January 2026 DA Hike: 58% to 60%
Here are the official numbers for the latest revision:
| Detail | Value |
|---|---|
| Previous DA | 58% (effective 1 July 2025) |
| Revised DA | 60% |
| Increase | 2 percentage points |
| Effective From | 1 January 2026 |
| Notification Date | Mid-April 2026 (Department of Expenditure OM) |
| Arrears Period | January, February, March, April 2026 (4 months) |
| Beneficiaries | ~50 lakh employees + ~67 lakh pensioners |
| Total Cost to Exchequer | ₹6,791.24 crore per year |
The same hike applies to Dearness Relief (DR) for pensioners and family pensioners.
How DA Arrears are Calculated
The arrears calculation has two components — most employees forget the second one and end up with a wrong number:
Component 1: DA on Basic Pay
This is the obvious part. Your DA increased from 58% of Basic Pay to 60% — a 2% increase.
Component 2: DA on Transport Allowance (TA)
Many employees miss this. TA itself is not DA-indexed, but a percentage of TA is added as DA. So when DA goes up, the DA-on-TA component also goes up by 2%.
Total Monthly Increase
Add both components, then multiply by the number of arrears months (4 in this case for Jan–Apr 2026):
Step-by-Step Calculation with Real Examples
Example 1: Level 6 Employee (Inspector / Section Officer)
- Basic Pay: ₹35,400
- Transport Allowance (Y-class city): ₹3,600
- Monthly DA increase = (35,400 + 3,600) × 2% = ₹780
- Arrears for 4 months = 780 × 4 = ₹3,120
Example 2: Level 8 Employee (Assistant Audit Officer / Section Officer)
- Basic Pay: ₹47,600
- Transport Allowance (Y-class city): ₹3,600
- Monthly DA increase = (47,600 + 3,600) × 2% = ₹1,024
- Arrears for 4 months = 1,024 × 4 = ₹4,096
Example 3: Level 10 Officer (Group A entry-level)
- Basic Pay: ₹56,100
- Transport Allowance (X-class city, ₹7,200 + DA on TA): ₹7,200
- Monthly DA increase = (56,100 + 7,200) × 2% = ₹1,266
- Arrears for 4 months = 1,266 × 4 = ₹5,064
Example 4: Level 14 Senior Officer
- Basic Pay: ₹1,44,200
- Transport Allowance: ₹7,200
- Monthly DA increase = (1,44,200 + 7,200) × 2% = ₹3,028
- Arrears for 4 months = 3,028 × 4 = ₹12,112

Note: Actual amounts vary based on your specific Basic Pay (within the Pay Matrix), city of posting (X/Y/Z TA rates), and any special pay components.
DA Arrears for Pensioners (Dearness Relief)
For pensioners, the calculation is simpler because DR (Dearness Relief) only applies to the basic pension — there is no TA component:
Pensioner Examples
- Pension ₹20,000: 20,000 × 2% × 4 = ₹1,600 arrears
- Pension ₹35,000: 35,000 × 2% × 4 = ₹2,800 arrears
- Pension ₹50,000: 50,000 × 2% × 4 = ₹4,000 arrears
- Pension ₹80,000: 80,000 × 2% × 4 = ₹6,400 arrears
The same applies to family pensioners. Both regular pensioners and family pensioners are credited the arrears in the same month the revised DR is implemented.
Are DA Arrears Taxable?
Yes. DA arrears are taxable as part of your salary income in the financial year they are received. However, you have an important relief option: Section 89(1) relief.
What is Section 89(1) Relief?
If receiving the arrears in one lump sum pushes you into a higher tax bracket, you can spread the arrears back to the years they relate to (using Form 10E) and pay tax based on the rates of those years. This often saves tax for senior employees.
Who Should File Form 10E?
- If you got arrears for multiple months/years and your bracket would have been lower
- Particularly relevant for employees who got revised pay arrears spanning multiple FYs
- Must be filed before filing your ITR for the year
What to Expect: July 2026 DA Hike
Based on the latest AICPI-IW data (March 2026 reading: 148.5; February: 148.6), tracking projections suggest the next DA revision in July 2026 will likely take DA to 62–63%. This is just a projection based on the formula, not an official announcement.
Once announced (probably September–October 2026), you can expect:
- Arrears for July, August, September 2026 (3 months)
- Effective rate of 62% or 63% (2–3 percentage points up from 60%)
- Paid as a lump sum along with the notification month's salary
Frequently Asked Questions
Why was the DA hike announced 4 months late?
The Cabinet typically waits for the AICPI-IW data for at least 6 months of the new cycle before formally approving the rate. Once approved, the Department of Expenditure issues the Office Memorandum (OM), and the new rate is implemented in salaries. The retrospective effect from 1 January is mandatory under DA rules — that's why arrears are always paid.
How will I know my exact arrears amount?
Check your April or May 2026 salary slip — there will be a separate line item for "DA Arrears" or "DR Arrears" showing the lump sum credited. Some PAOs split it across two months; check both salary slips.
Is DA included in HRA calculation?
No. HRA is calculated only on Basic Pay (excluding DA). However, for tax exemption under Section 10(13A), the formula uses Basic Pay + DA (only the part that counts for retirement benefits). For most central govt employees, the full DA counts.
Does DA hike affect my NPS contribution?
Yes. NPS contributions (10% from employee, 14% from government) are calculated on Basic Pay + DA. So a higher DA means a slightly higher NPS contribution as well. You can compare schemes using our NPS vs OPS vs UPS calculator.
Will the 8th CPC affect DA calculation?
Yes — significantly. When the 8th Pay Commission is implemented (expected from 1 January 2027), DA will be reset to 0% on the new (higher) Basic Pay. So enjoy the high DA rates while they last; under the new pay structure, DA starts fresh.
I'm a State Government employee. Does this apply to me?
Most state governments follow the central DA rates with a delay of 1–6 months. Check your state's Finance Department circulars. Some states have different rates entirely (e.g., West Bengal). The formula is the same; only the timing differs.
