Income Tax Act 1961 | Chapter XII
Section 110 of the Income-tax Act, 1961: Determination of Tax Where Total Income Includes Income on Which No Tax Is Payable
Section 110 provides a specific method of tax relief when an amount forms part of an assessee's total income but no income-tax is payable on that amount under the applicable provisions. Instead of simply ignoring that amount when computing tax, the section grants a deduction from the tax calculated on total income, using the average rate of income-tax.
Section 110: Statutory provision
The substantive wording in the uploaded source reads:
Where there is included in the total income of an assessee any income on which no income-tax is payable under the provisions of this Act, the assessee shall be entitled to a deduction, from the amount of income-tax with which he is chargeable on his total income, of an amount equal to the income-tax calculated at the average rate of income-tax on the amount on which no income-tax is payable.
Legislative note: The source records that Section 110 was substituted by Act 10 of 1965, section 32, with effect from 1 April 1965. This historical amendment note is retained for reference.
Meaning and scope of Section 110
1. Income included in total income
The provision concerns an amount that is included in total income even though no income-tax is payable on that amount under the applicable law. This is different from an amount that is excluded from total income altogether.
2. Deduction from tax, not from income
The relief operates by reducing the income-tax chargeable on total income. It is not a deduction from gross total income or a general exemption for all receipts.
3. Average rate of income-tax
For the purpose of this calculation, the average rate is the income-tax calculated on total income divided by total income, expressed as a percentage. The precise calculation must reflect the statutory meaning of income-tax and the rates applicable to the relevant year.
4. Relief is limited to qualifying income
Only income that satisfies the statutory condition can be used for the Section 110 deduction. Whether an item qualifies must be determined from the specific charging, exemption and rate provisions applicable to it.
How to calculate relief under Section 110
Average tax rate = Income-tax calculated on total income / Total income
Section 110 tax deduction = Average tax rate x qualifying income on which no tax is payable
Tax after Section 110 deduction = Tax calculated on total income - Section 110 tax deduction
The computation above explains the statutory mechanism. Cess, surcharge, rebates, special rates, rounding and other applicable adjustments must be considered in their legally prescribed sequence for the relevant year.
Illustrative calculation
Assume, solely to illustrate the formula, that total income is Rs. 10,00,000, tax calculated on total income before Section 110 relief is Rs. 1,00,000, and Rs. 2,00,000 of that total income is qualifying income on which no tax is payable.
| Particulars | Illustrative amount |
|---|---|
| Total income | Rs. 10,00,000 |
| Tax on total income before Section 110 relief | Rs. 1,00,000 |
| Average rate of income-tax | 10% |
| Qualifying non-taxable income included in total income | Rs. 2,00,000 |
| Deduction under Section 110 (10% of Rs. 2,00,000) | Rs. 20,000 |
| Tax after illustrative Section 110 deduction | Rs. 80,000 |
This is a mathematical illustration, not a statement of the tax slabs or an assertion that any particular category of income automatically qualifies for relief.
Section 110 compared with exemptions and other reliefs
- Exempt income: Income excluded from total income generally does not enter the Section 110 computation merely because it is tax-free.
- Income taxed at a special rate: Special-rate income is not necessarily income on which no tax is payable; the applicable charging and rate provisions must be checked.
- Rebates and deductions: Section 110 is a deduction from computed tax on specified income, not a substitute for deductions or rebates elsewhere in the Act.
- Tax treaties: Treaty relief and foreign-tax credit follow their own provisions. They should not be equated automatically with Section 110 relief.
Practical compliance points
Identify the precise provision that makes tax not payable on the relevant amount, verify that it is included in total income, calculate the average tax rate for the relevant assessment year, and retain a clear computation showing how the deduction was derived.
Frequently asked questions
Does Section 110 make all exempt income eligible for tax relief?
No. The section requires qualifying income to be included in total income and to be income on which no tax is payable under the Act. Income excluded from total income does not meet that description merely because it is exempt.
Is Section 110 a deduction from taxable income?
No. The deduction is from the amount of income-tax chargeable on total income.
Does Section 110 apply to tax years beginning on or after 1 April 2026?
Tax years governed by the Income-tax Act, 2025 must be assessed under that Act and its applicable rules and transitional provisions. Section 110 of the 1961 Act is referenced here for years and matters governed by the earlier Act.
