What are Salary Arrears?
Salary arrears refer to the unpaid difference between a revised salary and the old salary for past months. When an employer announces a salary revision, increment, or Dearness Allowance (DA) hike with retrospective effect, the employee was paid at the old rate during those months. The pending difference for all those months is called salary arrears or arrears of pay.
For example, if your company announces your appraisal effective from April but processes it in August, you are owed the salary difference for April, May, June, and July. This cumulative amount is your salary arrears. It is usually paid as a lump sum in the month the revision is processed. The arrears amount reflects in your salary slip and is reported separately for tax purposes.
- Arrears arise when a salary revision is applied retroactively but payments were made at the old rate
- Common in delayed appraisals, government DA revisions, Pay Commission implementations, and court-ordered salary corrections
- Arrears are paid as a lump sum and are fully taxable in the year of receipt
- Employees can claim tax relief under Section 89(1) by filing Form 10E on the Income Tax e-filing portal
How are Salary Arrears Calculated?
The salary arrears formula is straightforward. You need three inputs: the old monthly salary, the revised monthly salary, and the number of months the revision applies retroactively.
Arrears = (Revised Monthly Salary - Old Monthly Salary) x Pending Months
The "pending months" is the period between the effective date of the revision and the month in which the revised salary is actually paid. For government employees receiving DA arrears, this period can range from 6 to 18 months depending on when the central government processes the revision.
Keep in mind that the gross arrears amount is not what you receive in hand. Your employer will deduct the differential PF contribution for those months, professional tax adjustments, and TDS on the arrears before crediting the net amount.
Important: If the salary revision changes your basic salary, your PF and gratuity contributions for the arrear months also need to be recalculated. The employer deducts the differential PF (both employee and employer share) from the arrears payment. This reduces the actual in-hand arrears amount.
Salary Arrears Calculation with Example
Let's calculate the arrears for an employee whose salary was revised from ₹40,000 to ₹48,000 per month, effective from April, but processed in August (4 months pending).
Old Monthly Salary: ₹40,000
Revised Monthly Salary: ₹48,000
Monthly Difference: ₹48,000 - ₹40,000 = ₹8,000
Pending Months: 4 (April, May, June, July)
Total Salary Arrears: ₹8,000 x 4 = ₹32,000
The employee will receive ₹32,000 as gross arrears in the August salary. After PF deduction on the differential basic (approximately ₹1,920 assuming 12% on ₹4,000 basic difference per month x 4), the net arrears will be around ₹30,080 before TDS. Use the TDS Calculator to estimate the tax impact on your arrear payment.
Why are Salary Arrears Important?
Salary arrears impact multiple aspects of your finances and compliance. Here is why understanding arrears matters for both employees and HR teams:
- Tax planning: Arrears are taxed in the year they are received, not the year they relate to. This lump sum can push you into a higher tax bracket. Filing Form 10E for Section 89 relief can reduce the excess tax burden
- PF recalculation: When basic salary changes retroactively, PF contributions for those months need to be recalculated. Both employee and employer share are adjusted, affecting the total arrears payout
- Salary slip accuracy: Arrears must be shown as a separate line item in the payslip for the month of payment. Incorrect reporting can cause discrepancies in Form 16 and the Annual Information Statement
- Loan applications: Arrear payments increase the gross income for the month they are paid. Employees can use the arrears month salary slip to demonstrate higher income during loan or credit card applications
- HR compliance: For payroll teams, processing arrears correctly requires recalculating multiple components. Late or incorrect arrears processing can lead to employee grievances and compliance issues

Section 89 Tax Relief on Salary Arrears
When you receive salary arrears as a lump sum, it gets added to your income for that financial year. This can push your total income into a higher tax slab, resulting in a higher tax liability than what you would have paid if the salary had been paid on time each month.
Section 89(1) of the Income Tax Act provides relief in such cases. The relief is calculated by comparing two scenarios:
- Scenario A: Calculate tax on total income including arrears in the year of receipt
- Scenario B: Calculate tax as if the arrears were spread across the years they actually relate to
- Relief amount: If tax in Scenario A is higher than Scenario B, the excess is the Section 89 relief
How to claim: File Form 10E on the Income Tax e-filing portal before filing your ITR. Go to e-File > Income Tax Forms > Form 10E, fill in the arrears details and compute the relief. Without Form 10E, the tax department will not allow the Section 89 deduction even if you claim it in your ITR.
To understand how salary arrears affect your overall tax computation, you can compare the impact under both tax regimes using the Old vs New Tax Regime Calculator.
When Do Salary Arrears Arise?
Salary arrears can arise in several scenarios across both private and government sectors. Here are the most common situations:
| Scenario | Typical Arrear Period | Who It Affects |
| Delayed annual appraisal | 2 to 6 months | Private sector employees |
| DA (Dearness Allowance) revision | 6 to 12 months | Government and PSU employees |
| Pay Commission implementation | 12 to 24 months | Central and state government employees |
| Promotion with backdated effect | 1 to 6 months | All sectors |
| Court-ordered salary revision | Varies | Employees with pending labor disputes |
| Minimum wage revision | 3 to 12 months | Workers covered under minimum wage acts |
For private sector employees, the most common scenario is a delayed appraisal cycle. Many companies conduct appraisals between January and April but process the revised salary only in June or July, creating 2 to 4 months of arrears. Employees should verify their revised salary breakup to ensure all components are correctly updated. HR teams can use the Payroll Processing Checklist to ensure arrears are calculated and paid correctly during revision cycles.
