The Income Tax Arrears Relief Calculator for FY 2026 27 helps taxpayers compute relief under Section 89(1)[ Amended Section 157(1) under Rule 73] of the Income Tax Act 2025. When arrears increase taxable income in one year, the calculator spreads them across relevant years, ensuring fair taxation. It simplifies complex Rule 73 calculations, saves time, and generates accurate figures for Form 10E filing. By following a step-by-step process—entering current and past incomes, computing additional tax, and comparing differences—taxpayers can claim rightful relief. Ultimately, the tool enhances compliance, reduces errors, and empowers individuals to manage arrears efficiently while lowering unnecessary tax burdens.
Introduction
When employees receive arrears due to retrospective salary revisions, promotions, or pay commission recommendations, their taxable income for a single year increases sharply. Consequently, this bunching of income leads to higher tax liability. To address this, Section 89(1)[Amended Section 157(1) under Rule 73 of the Income Tax Act 2025] provides relief. With the Automated Arrears Relief Calculator for FY 2026‑27, taxpayers can compute relief quickly, accurately, and in compliance with the law. This article explains the process step by step, ensuring clarity and confidence in tax filing.
Understanding Arrears Relief under Section 89(1)[ Amended Section 157(1) Under Rule 73 of the Income Tax Act 2025]
Arrears relief ensures taxpayers do not suffer undue tax burden when income is received late but relates to earlier years. Instead of taxing arrears entirely in FY 2026‑27, the law allows recalculation by spreading arrears across the relevant years. Therefore, taxpayers pay just the actual tax gap, not an exaggerated burden.
Why Use an Automated Calculator?
Manual calculations under Rule 73[Previously known as Rule21A] are complex. Therefore, the automated arrears relief calculator simplifies the process. Moreover, it ensures compliance with the Income Tax Act 2025, reduces errors, and generates ready‑to‑use figures for Form 10E[now amended and known as Form 39], which is mandatory for claiming relief. Additionally, it saves time, improves accuracy, and enhances transparency.
Step‑by‑Step Guide to Calculate Arrears Relief
Step 1: Collect Salary Records
First, gather salary slips, Form 16, and arrears statements. Then, identify the years to which arrears belong. Without accurate records, relief calculation may be incorrect.
Step 2: Enter Current Year Income
Now, add the total FY 2026‑27 income, factoring in arrears. The calculator computes tax liability for the current year.
Step 3: Enter Previous Year Income
Afterwards, enter income for each year to which arrears relate. The calculator compares tax liability with and without arrears for those years.
Step 4: Compute Additional Tax
Subsequently, the calculator determines the additional tax payable due to arrears in FY 2026‑27.
Step 5: Compare Tax Differences
Then, it compares the additional tax with the tax that would have been payable if arrears were taxed in the relevant years.
Step 6: Calculate Relief Amount
Finally, the calculator provides the relief amount under Section 89(1). This amount reduces tax liability in FY 2026‑27.
Example Illustration
Suppose a taxpayer receives arrears of ₹2,50,000 in FY 2026‑27 for FY 2023‑24 and FY 2024‑25. The calculator spreads arrears across those years, recalculates tax, and shows relief. Consequently, the taxpayer pays only the fair difference, not the inflated tax.

· Speed: Provides instant results.
· Compliance: Aligns with Section 89(1) and Rule 21A.
