Working for yourself gives you freedom, but it also makes you responsible for your own records. The Income-tax Act sets out when freelancers and independent professionals must maintain books of account, what those records should cover, and when a tax audit kicks in. Getting this right keeps your return clean and protects you if questions ever arise. Here's a plain-language guide.

Quick answer
Freelancers and independent professionals have specific rules on keeping books of account and on when a tax audit applies. Here's what you need to maintain and when.
Whether you are required to maintain books depends largely on your income and receipts. Once your professional income or gross receipts cross prescribed limits, formal books become mandatory. Below those limits the obligation is lighter, but keeping basic records is still strongly advisable. If you opt into presumptive taxation under Section 44ADA — declaring at least 50% of gross receipts as income, available up to a receipts limit of Rs 50 lakh (raised to Rs 75 lakh where cash receipts stay within 5%) — you are generally relieved from maintaining detailed books, which is part of that scheme's appeal.
Where books are required, you should keep a record of your receipts and payments, the work you billed for, and supporting documents. In practice this means invoices you raise, bank statements, expense bills, and records of any assets used in your work. Even a simple, consistent system — a cashbook or accounting app reconciled to your bank — goes a long way. The aim is that anyone reading your records can trace each figure in your return back to a source document.
A freelancer who keeps proper books can deduct genuine business expenses incurred to earn income — things like software subscriptions, professional fees, a share of internet and phone costs, and depreciation on equipment. The key is that expenses must be genuine, business-related and supported by evidence. This is the trade-off against presumptive taxation: keeping books takes effort but lets you claim real expenses, which helps if your actual margin is lower than the presumptive percentage.
If your receipts cross the audit threshold for professionals, a tax audit under Section 44AB becomes mandatory and a chartered accountant must examine your books. An audit can also be triggered if you declare income below the presumptive rate while your total income exceeds the basic exemption limit. Because the exact threshold and the cash-proportion relaxations depend on your situation, check where you stand before assuming you are clear of audit.
Maintaining books is not only about the current year. You are expected to retain your records for a number of years so they are available if your return is examined later. Good retention — organised digital copies of invoices, bank statements and expense proofs — means that if a query arises long after filing, you can respond quickly and confidently. Treat record-keeping as an ongoing habit rather than a year-end scramble.
It depends on your income and receipts — once they cross the prescribed limits, formal books are mandatory. Below those limits the obligation is lighter, and if you opt for presumptive taxation under Section 44ADA you are generally relieved from detailed books, though keeping basic records is always wise.
Yes, if you maintain proper books you can deduct genuine business expenses incurred to earn your income , supported by invoices and proofs. If instead you use presumptive taxation under 44ADA, you declare at least 50% of receipts as income and cannot separately claim expenses.
A tax audit under Section 44AB applies once your professional receipts cross the prescribed threshold , and can also be triggered if you declare income below the presumptive rate while your total income exceeds the basic exemption limit. The exact limits depend on your cash proportion, so confirm where you stand.
