1. Understanding Section 89(1)
Section 89(1) of the Income Tax Act, 1961 helps taxpayers avoid unfair tax burdens when they receive delayed salary, pension, or arrears. It spreads the extra income over the years it actually belongs to, lowering your tax liability.
2. When You Can Claim Arrears Relief
You can claim relief under Section 89(1) if you receive:
- Salary arrears due to the pay revision
- Bonus or incentive for past years
- Pension arrears
- Family pension arrears
In short, if the payment belongs to earlier years but you got it now, you may qualify.
3. Why Form 10E Is Mandatory
The Income Tax Department insists on filing Form 10E online before claiming relief. Without it, even if you are eligible, your claim may be rejected. Think of Form 10E as your official ticket for the tax benefit.
4. How Arrears Affect Your Tax Liability
When arrears are added to your current year’s income, they can push you into a higher tax slab. Section 89(1) adjusts this by calculating your tax as if the arrears were received in the correct years.
Example: If you earn ₹6 lakh normally, but with arrears it becomes ₹8 lakh, you might jump into the 20% slab. Section 89(1) ensures you pay fair tax.
5. Step-by-Step Relief Calculation Process
The process involves four main steps:
- Calculate tax for the current year, including arrears
- Calculate tax for the current yea,r excluding arrears
- Calculate the difference for past years with and without arrears
- Relief = Extra tax paid in the current year – Extra tax that would have been paid in past years
6. Calculating Tax for the Current Year with Arrears
You first add arrears to your current salary and compute tax as per the latest slab rates.
Example:
- Current salary: ₹6,00,000
- Arrears: ₹2,00,000
- Total: ₹8,00,000
- Tax = Apply slab rates to ₹8,00,000.
7. Calculating Tax for the Current Year without Arrears
Now, calculate tax as if you had never received the arrears this year.
Example:
- Income: ₹6,00,000
- Tax = Apply slab rates to ₹6,00,000.
8. Calculating Tax for the Past Years Separately
For each year the arrears belong to, compute the tax with and without the arrears amount for that year, using the slab rates of that specific year.
9. Finding the Relief Amount
Relief is simply:
sqlCopyEditRelief = (Tax on total current year income – Tax without arrears) – (Tax for past years with arrears – Tax without arrears for those years)
If this amount is positive, that’s your relief under Section 89(1).
