Profits and gains of business or profession is the head that applies to a trade, manufacture, or specified profession, and to many freelance and consulting practices. The taxable figure is profit: receipts minus the expenditure the statute allows, or, where a presumptive scheme is validly used, a prescribed percentage of turnover or receipts. This article introduces that computation. The next article addresses planning and compliance for owners and freelancers. Nothing here is a licence to mix household expenditure with business expenditure, or to treat informal cash receipts as being outside the statute.

"Business income is profit, not turnover. A large receipt from clients is not, by itself, a large taxable figure, and a small receipt is not, by itself, a small one.

Who Falls under This Head

A shopkeeper, a manufacturer, a consultant, a physician in private practice, a designer who invoices clients, and a person who carries on a systematic activity with a profit motive may all fall under this head. Employment remains under salaries. A single individual may have both: a salary from one engagement and professional receipts from another. Each is computed separately.

Books, Bank Accounts and Evidence

The statute expects a record of receipts and of expenditure that is claimed. A separate bank account for the activity is not a legal magic, but it is the most reliable method of showing which credits are professional and which are personal. Invoices, goods-received notes where relevant, and proofs of expenditure are the material on which a deduction stands. Expenditure that cannot be shown is not made allowable by being described as β€œfor the business.”

Presumptive Schemes

Specified resident taxpayers whose turnover or receipts do not exceed the prescribed thresholds may compute profit as a percentage of turnover or receipts under the presumptive provisions β€” commonly discussed as section 44AD for eligible businesses and section 44ADA for specified professions. The percentages and the turnover limits are statutory and have been amended from time to time; they must be read for the year in question. A person who opts for a presumptive scheme is relieved of certain book-keeping requirements, and is also constrained: deductions under the business head are generally taken to be embedded in the prescribed percentage. Leaving the scheme, or declaring a lower profit than the prescribed percentage, can bring additional obligations, including audit in specified cases.

Allowable Expenditure in Outline

Where profit is computed in the ordinary way, expenditure laid out wholly and exclusively for the business or profession is allowable, subject to specific disallowances. Capital expenditure is not deducted in full in the year of purchase; depreciation is allowed on specified assets at prescribed rates. Household rent, family travel and personal drawings are not business expenditure. Mixed-use assets require an honest apportionment.

Did You Know?

Once a person with business income leaves the older tax regime in circumstances the statute treats as final, the option to return to that regime may be restricted. Regime choice for a proprietor is therefore not always an annual convenience of the kind available to a salaried individual without business income.

A Real Household Story

Devika, a graphic designer in Tezpur, invoiced clients from the same account into which her spouse’s salary was credited, and withdrew cash for both household and software subscriptions. At the end of the year she could not separate professional receipts from family credits with confidence. She opened a dedicated account the following April, issued invoices from that account, and paid personal drawings by transfer. The tax rate did not change. The quality of the computation did.

MoneyChanakya Insight

Presumptive taxation is a simplification of computation. It is not a simplification of the duty to receive payment through identifiable channels, or to know whether the year’s receipts remain within the prescribed threshold.

Common Mistake

Declaring a profit lower than the presumptive percentage without accepting the book-keeping and audit consequences that then apply. The percentage and the relief travel together.

Key Takeaways

  • Business and professional income is profit, computed either in the ordinary way or under a presumptive scheme.
  • Books, a dedicated account and evidence of expenditure are the foundation of any claim.
  • Presumptive percentages and turnover limits must be read for the year of filing.
  • The next article turns to planning that remains within the statute: depreciation, timing, compliance and the limits of what may be claimed.
