Section 89 Arrears Relief Calculator (Form 10E)

⚡ In shortIf you receive salary arrears — a delayed pay revision, a back-dated promotion, or a settlement — the whole amount lands in one year and can push you into a higher slab, even though you should have earned it gradually. Section 89(1) exists to undo that unfairness. Relief under section 89(1) is the difference between two figures: the extra tax you pay because the arrears were taxed in the year you received them, and the extra tax you would have paid had the arrears been taxed in the years they actually related to. If taxing it in the earlier years would have cost less, the difference is your relief and it is deducted from this year's tax. Claiming it is conditional: you must file Form 10E on the income-tax e-filing portal BEFORE filing your ITR — if you skip it, the department will disallow the relief and issue a demand, which is one of the most common reasons a 143(1) intimation shows extra tax. This calculator gives an indicative figure using current slabs; your CA will compute it with each year's actual slabs.

Frequently asked questions

Is Form 10E mandatory for section 89 relief?

Yes. Relief under section 89(1) is disallowed if Form 10E is not filed on the e-filing portal before you file your return. This is a very common cause of a 143(1) demand.

What kind of income qualifies for section 89 relief?

Salary arrears or advance salary, gratuity, commuted pension, retrenchment compensation and certain other lump sums that relate to more than one year.

Do I need to attach Form 10E to my ITR?

No — you file it separately online on the income-tax portal. Keep the acknowledgement; you do not upload it with the return.

Is the relief available under the new tax regime?

Section 89 relief is a computation of tax, not a Chapter VI-A deduction, so it is available under either regime — but the arithmetic changes with the slabs you are taxed under.
