Section 89(1) Relief on Salary Arrears & Bonus: How to Reduce Your Tax Liability for AY 2026-27

If you received salary arrears, a one-time bonus, or any past-due compensation this year, you may have noticed your tax liability jumping sharply. That spike happens because the entire lump sum gets added to your current year's income, potentially pushing you into a higher tax slab. Section 89(1) of the Income Tax Act exists precisely to fix this — it ensures you are not penalized for receiving income that actually belongs to earlier years.

This guide walks you through how Section 89(1) relief works, how to calculate it, and how to file Form 10E to claim it for AY 2026-27.

When Does Section 89(1) Apply?

Section 89(1) provides relief when you receive salary or other specified income in arrears or in advance. Common scenarios include:

• Salary arrears — your employer revises your pay structure or the pay commission announces a hike with retrospective effect
• Bonus or commission relating to earlier financial years paid in the current year
• Arrears of family pension received as a lump sum
• Gratuity, commuted pension, or leave encashment received in a year other than the year of retirement
• Compensation on termination or modification of employment terms

The key condition: the income must relate to a period other than the year in which it is received. If your entire bonus is for the current year's performance and paid in the same year, Section 89(1) does not apply.

How the Relief Calculation Works

The logic is straightforward — compare two scenarios and pay the lower tax:

1. Tax on total income including arrears (what you would normally pay)
2. Tax on total income excluding arrears + Tax on arrears as if received in the correct year

The difference between scenario 1 and scenario 2 is your Section 89(1) relief.

Step-by-Step Calculation

Let us work through a realistic example.

Rajesh's situation (AY 2026-27 / FY 2025-26):

• Regular salary income in FY 2025-26: Rs 10,00,000
• Salary arrears received: Rs 3,00,000 (relating to FY 2023-24)
• His total income in FY 2023-24 (as originally filed): Rs 8,50,000
• He uses the new tax regime

Step 1: Calculate tax on total income including arrears

Total income for FY 2025-26 = Rs 10,00,000 + Rs 3,00,000 = Rs 13,00,000

Under the new regime for AY 2026-27:

Tax on Rs 13,00,000 = Rs 75,000 Add: Cess at 4% = Rs 3,000 Total tax (with arrears) = Rs 78,000

Step 2: Calculate tax on total income excluding arrears

Income without arrears = Rs 10,00,000

Tax on Rs 10,00,000 = Rs 40,000 Add: Cess at 4% = Rs 1,600 Total tax (without arrears) = Rs 41,600

Step 3: Calculate tax in the year the arrears relate to (FY 2023-24)

Original total income for FY 2023-24 = Rs 8,50,000 Revised total income = Rs 8,50,000 + Rs 3,00,000 = Rs 11,50,000

Tax on original income (Rs 8,50,000) under new regime (AY 2024-25 slabs):

Tax = Rs 40,000 + Cess = Rs 41,600

Tax on revised income (Rs 11,50,000) under the same year's slabs:

Tax = Rs 82,500 + Cess = Rs 85,800

Incremental tax in the arrears year = Rs 85,800 – Rs 41,600 = Rs 44,200

Step 4: Compare and compute relief

Since the tax with arrears (Rs 78,000) is lower than the alternative (Rs 85,800), Rajesh does not get any relief in this case — the current year taxation is already more favorable.

Now consider a different scenario where Rajesh's regular salary was Rs 14,00,000 instead:

Tax with arrears on Rs 17,00,000 would be Rs 1,53,400 (including cess). Tax without arrears on Rs 14,00,000 would be Rs 1,04,000. The incremental tax in the arrears year remains Rs 44,200. So the alternative total is Rs 1,48,200.

Relief = Rs 1,53,400 – Rs 1,48,200 = Rs 5,200

The higher your current income, the more likely Section 89(1) saves you money because the arrears push you deeper into higher slabs.

How to File Form 10E Online

Claiming Section 89(1) relief is mandatory through Form 10E. You must file it before filing your ITR — without it, the income tax department will not process the relief.

Filing Steps on the Income Tax Portal

1. Log in to the income tax e-filing portal with your PAN and password
2. Navigate to e-File → Income Tax Forms → File Income Tax Forms
3. Search for Form 10E and select it
4. Choose the relevant Assessment Year (AY 2026-27)
5. Fill in the details:
   • Annexure I — for salary arrears or advance salary received under Section 89(1)
   • Annexure II — for gratuity
   • Annexure III — for commuted pension
   • Annexure IV — for leave encashment
6. Enter your income and tax details for the current year and the year(s) the arrears relate to
7. The portal auto-calculates the relief amount
8. Submit and verify with OTP, DSC, or EVC

The form auto-populates some data from your previous returns. Keep your Form 16, salary slips, and the arrears breakup letter from your employer handy.

Where to Report Section 89 Relief in Your ITR

After filing Form 10E, report the relief in your income tax return:

• In ITR-1: Under the "Tax Computation" section, there is a field for "Relief under Section 89." Enter the amount calculated in Form 10E.
• In ITR-2: The field appears under "Part B – Tax computation and tax status," in the row for relief under Section 89.

49Tax automatically detects arrears income from your Form 16 and flags the Section 89(1) opportunity during the review step, so you do not miss it.

Section 89 and the New vs Old Tax Regime

Section 89(1) relief applies regardless of whether you are in the old or new tax regime. However, there are some practical considerations:

• Consistency matters: When calculating the hypothetical tax for the arrears year, you must use the same regime you actually filed under for that year. You cannot switch regimes hypothetically to get a better relief amount.
• Higher impact under old regime: Since the old regime has steeper slab jumps (after deductions), arrears income often causes a bigger slab impact, making Section 89 relief larger.
• New regime simplicity: With flatter slabs in the new regime, the relief amount tends to be smaller but the calculation is simpler.

If you are unsure which regime you used in the year the arrears relate to, check your filed ITR for that year on the income tax portal.

Arrears Spread Across Multiple Years

Sometimes arrears relate to more than one financial year — for instance, a government pay commission revision might cover three years of backpay. In this case:

1. Split the total arrears into amounts attributable to each year
2. Perform the Step 3 calculation separately for each year
3. Sum up the incremental taxes across all years
4. Compare the combined alternative with the current year tax as before

Your employer's arrears breakup letter should specify the year-wise allocation. If it does not, request one — without it, you cannot accurately file Form 10E.

Important Points to Remember

Deadline: Form 10E must be filed before your ITR. There is no separate deadline, but if you file your ITR without it, the CPC (Centralized Processing Centre) will disallow the relief and you will receive an intimation under Section 143(1) with higher tax demand.

No revised Form 10E: Unlike ITRs, Form 10E cannot be revised after submission. Double-check your numbers before filing.

Employer's role: Your employer may or may not account for Section 89 relief while computing TDS. If they do, it will reflect in your Form 16 Part B. If they do not, you claim it yourself when filing the return.

Relief cannot exceed tax: The relief amount under Section 89 is capped at the difference in tax — it cannot create a refund on its own beyond what was already deducted as TDS.

Not applicable for pension arrears under NPS: Regular NPS contributions and annuity do not qualify. However, arrears of family pension received after the pensioner's death do qualify.

When Section 89 Relief Is Not Available

The relief does not apply when:

• The income is entirely attributable to the current year (no arrears component)
• You received compensation under a voluntary retirement scheme — this is covered under Section 10(10C) exemption instead
• The arrears relate to non-salary income like rental income or business income
• You fail to file Form 10E before your ITR

Actionable Takeaway

If you received any salary arrears, back-dated bonus, or retrospective pay revision this year, do not simply accept the higher tax bill. Calculate your Section 89(1) relief using the steps above, file Form 10E on the income tax portal, and claim it in your ITR. For most salaried taxpayers in the Rs 10-20 lakh bracket receiving even Rs 1-2 lakh in arrears, the relief can save Rs 2,000 to Rs 15,000 depending on which slabs the arrears straddle. The ten minutes it takes to file Form 10E is well worth it.
