Dear Sir,
Hope you are doing well !!
If tuition is your only profession then Income from tuition will be your main source of income and taxable under the head Income from Business/Profession. However, if you are in receipt of any other main source of income like salary income, house property income or income from other business and in addition to this you are giving tuition, then such tuition income will be taxable under the head “Income from other Sources.
We may help you in filing return.
