Step 1 – Determination of residential status

The residential status of a person has to be determined to ascertain which income is to be included in computing the total income.

The residential status as per the Income Tax Act, 1961 can be classified as under –



In the case of an individual, the duration for which he is present in India determines his residential status. Based on the time spent by him, he may be (a) resident and ordinarily resident, (b) resident but not ordinarily resident, or (c) non-resident.

The residential status of a person determines the taxability of the income. For e.g., income earned and received outside India will not be taxable in the hands of a nonresident but will be taxable in case of a resident and ordinarily resident.

Step 2 – Classification of income under different heads

The Act prescribes five heads of income. These are shown below –

Heads of Income in India under Income Tax Act 1961

There is a charging section under each head of income which defines the scope of income chargeable under that head. These heads of income exhaust all possible types of income that can accrue to or be received by the tax payer. Accordingly, the income is classified as follows:

  1. Salary, pension earned is taxable under the head “Salaries”.
  2. Rental income is taxable under the head “Income from house property”.
  3. Income derived from carrying on any business or profession is taxable under the head “Profits and gains from business or profession”.
  4. Profit from sale of a capital asset (like land) is taxable under the head “Capital Gains”.
  5. The fifth head of income is the residuary head. The income which is not taxable under the first four heads will be taxed under the head “Income from other sources”.

The tax payer has to classify the income earned under the relevant head of income.

Step 3– Computation of income under each head

Income is to be computed in accordance with the provisions governing a particular head of income.

Exemptions: There are certain incomes which are wholly exempt from income-tax e.g. agricultural income. These incomes have to be excluded and will not form part of Gross Total Income.

Also, some incomes are partially exempt from income-tax e.g. House Rent Allowance, Education Allowance. These incomes are excluded only to the extent of the limits specified in the Act. The balance income over and above the prescribed exemption limits would enter computation of total income and have to be classified under the relevant head of income.

Deductions: There are deductions and allowances prescribed under each head of income. For example, while calculating income from house property, municipal taxes and interest on loan are allowed as deduction. Similarly, deductions and allowances are prescribed under other heads of income. These deductions etc. have to be considered before arriving at the net income chargeable under each head.

Step 4 – Clubbing of income of spouse, minor child etc.

In case of individuals, income-tax is levied on a slab system on the total income. The tax system is progressive i.e., as the income increases, the applicable rate of tax increases. Some taxpayers in the higher income bracket have a tendency to divert some portion of their income to their spouse, minor child etc. to minimize their tax burden.

In order to prevent such tax avoidance, clubbing provisions have been incorporated in the Act, under which income arising to certain persons (like spouse, minor child etc.) have to be included in the income of the person who has diverted his income for the purpose of computing tax liability.

Step 5 – Set-off or carry forward and set-off of losses

An assessee may have different sources of income under the same head of income. He may have profit from one source and loss from the other. For instance, an assessee may have profit from his textile business and loss from his printing business. This loss can be set-off against the profits of textile business to arrive at the net income chargeable under the head “Profits and gains of business or profession”.

Similarly, an assessee can have loss under one head of income, say, Income from house property and profits under another heads of income, say, profits and gains of business or profession. There are provisions in the Income-tax Act, 1961 for allowing inter-head adjustment in certain cases.

However, there are also restrictions in certain cases, like business loss is not allowed to be set-off against salary income. Further, losses which cannot be set-off in the current year due to inadequacy of eligible profits can be carried forward for set-off in the subsequent years as per the provisions contained in the Act. Generally, brought forward losses under a particular head cannot be set-off against income under another head i.e., brought forward business loss cannot be set-off against income from house property of the current year.

Step 6 – Computation of Gross Total Income

The final figures of income or loss under each head of income, after allowing the deductions, allowances and other adjustments, are then aggregated, after giving effect to the provisions for clubbing of income and set-off and carry forward of losses, to arrive at the gross total income.

Step 7 – Deductions from Gross Total Income

There are deductions prescribed from Gross Total Income. These deductions are of three types –


  • Deductions in respect of certain payments
  • Deductions in respect of certain incomes
  • Deductions in respect of other income

Step 8 – Total income

The income arrived at, after claiming the above deductions from the Gross Total Income is known as the Total Income. It should be rounded off to the nearest multiple of ` 10. The process of computation of total income is shown hereunder –

Step 9 – Application of the rates of tax on the total income

The rates of tax for the different classes of assessees are prescribed by the Annual Finance Act.

For individuals, HUFs etc., there is a slab rate and basic exemption limit. At present, the basic exemption limit is ` 2,50,000 for individuals. This means that no tax is payable by individuals with total income of up to ` 2,50,000.

Those individuals whose total income is more than ` 2,50,000 but less than ` 5,00,000 have to pay tax on their total income in excess of ` 2,50,000 @ 5% and so on.

The highest rate is 30%, which is attracted in respect of income in excess of ` 10,00,000.

The tax rates have to be applied on the total income to arrive at the income-tax liability.

Step 10 – Surcharge / Rebate under section 87A

Surcharge: Surcharge is an additional tax payable over and above the income-tax. Surcharge is levied as a percentage of income-tax. In case where the total income of an individual/HUF/AOP/BOI exceeds Rs. 50 lakhs but does not exceed ` 1 crore, surcharge is payable at the rate of 10% of income-tax and in case total income exceeds ` 1 crore, surcharge is payable at the rate of 15% of income-tax.

Rebate under section 87A: In order to provide tax relief to the individual tax payers who are in the 5% tax slab, section 87A provides a rebate from the tax payable by an assessee, being an individual resident in India, whose total income does not exceed ` 3,50,000. The rebate shall be equal to the amount of income-tax payable on the total income for any assessment year or an amount of Rs. 2,500, whichever is less.

Level of Total Income Surcharge Rebate u/s 87A
≤ Rs. 3,50,000 Not applicable Income-tax on total income or Rs. 2,500, whichever is less
> Rs. 3,50,000 ≤ Rs. 50,00,000 Not applicable Not applicable
> Rs. 50,00,000 ≤ Rs. 1,00,00,000 10% of income-tax Not applicable
> Rs. 1,00,00,000 15% of income-tax Not applicable

Step 11 – Health and education cess on income tax

The income-tax, as increased by the surcharge or as reduced by the rebate under section 87A, if applicable, is to be further increased by an additional surcharge called health and education cess on income-tax @4% of income-tax plus surcharge, if applicable.

Step 12 – Advance tax and tax deducted at source

Although the tax liability of an assessee is determined only at the end of the year, tax is required to be paid in advance in four installments on the basis of estimated income i.e., on or before 15th June, 15th September, 15th December and 15th March. However, residents opting for presumptive taxation scheme can pay advance tax in one installment on or before 15th March instead of four installments. In certain cases, tax is required to be deducted at source from the income by the payer at the rates prescribed in the Income-tax Act, 1961 or the Annual Finance Act. Such deduction should be made either at the time of accrual or at the time of payment, as prescribed by the Act.

For example, in the case of salary income, the obligation of the employer to deduct tax at source arises only at the time of payment of salary to the employees. However, in respect of other payments like, fees for professional services, fees for technical services, interest made to residents, the person responsible for paying is liable to deduct tax at source at the time of credit of such income to the accounts of the payee or at the time of payment, whichever is earlier. Such tax deducted at source has to be remitted to the credit of the Central Government through any branch of the RBI, SBI or any authorized bank.  

Step 13: Tax Payable/Tax Refundable

After adjusting the advance tax and tax deducted at source, the assessee would arrive at the amount of net tax payable or refundable. Such amount should be rounded off to the nearest multiple of Rs 10.

The assessee has to pay the amount of tax payable (called self-assessment tax) on or before the due date of filing of the return. Similarly, if any refund is due, assessee will get the same after filing the return of income.
