For income earned from home tuition, it is generally treated as Income from Profession since it involves rendering teaching services using your personal skill and knowledge.
ITR-1 (Sahaj): Can be filed only for salaried individuals or income from other sources like bank interest. Tuition income does not fall here.
ITR-2: Applicable for income from salary, house property, capital gains, or other sources — but not for business/professional income.
ITR-3: Correct form for declaring income from business or profession, which includes tuition classes.
?? Therefore, in your case, since the housewife earns Rs. 25,000 per month through home tuition, she should file ITR-3 under the head “Profits and Gains from Business or Profession.”
If the turnover is below ?50 lakhs, she may also opt for Presumptive Taxation (u/s 44ADA), which simplifies filing by allowing 50% of the income as deemed expenses.
