Salary arrear calculation doubt

If income including arrears is considered in ITR in the previous years, do not consider it in the year of receipt.

If arrears is not included in income of earlier years in ITR, consider it now in the year of receipt.

Section 89(1) relief is the correct provision for salary arrears received in the current year but relating to earlier years. Here is how the calculation works.

The relief mechanism: Tax is computed as if the arrear were received in the year it pertained to (old year calculation) and the difference from actual current-year tax is allowed as relief. This prevents you from paying at a higher slab rate simply because the arrear came late.

Mandatory form: You must file Form 10E on the income tax portal BEFORE filing the ITR. If you claim 89(1) relief in the ITR without filing Form 10E, the system will reject the relief and issue a demand notice. Form 10E is filed under My Account > File Form 10E on the portal.

What you need for the calculation:
- Gross salary for the current year (including arrear)
- Break-up of arrear by the year(s) it belongs to
- Taxable income for those past years (from old ITRs or estimated computation)

The utility in Form 10E automatically computes the relief once you enter the year-wise arrear break-up and the corresponding income for each prior year.

Common mistake: People do not account for the arrear in the year-wise computation of past income. If you were in a lower bracket in the prior year but the arrear pushed you to a higher bracket, the calculation must reflect the marginal tax on just the arrear amount added to that year is income.
