Presumptive taxation or regular books — and the trap in leaving 44AD

Short answer: presumptive taxation under Section 44AD removes the need for books and audit, but leaving it is expensive — declaring income below the presumptive rate bars you from the section for five assessment years and, where your income exceeds the basic exemption limit, forces you into books and audit. Section 44ADA, for professionals, carries no such lock-in.

That asymmetry is the single most important thing to understand before electing either.

The two schemes

Section 44AE covers goods carriage on a per-vehicle basis and operates differently again.

What presumptive taxation gives you

The income is deemed. You do not claim business expenses separately — depreciation and expenditure are treated as already allowed in arriving at the presumptive figure. You are relieved of maintaining books under Section 44AA and of audit under Section 44AB for that activity, and advance tax can be paid in a single instalment by 15 March rather than four.

For a genuinely small operation with a healthy margin and modest compliance appetite, that is a real simplification.

The trap in Section 44AD(4)

Here is the mechanism, because it is rarely explained before someone elects into the scheme.

If you declare income under Section 44AD in a year, and then in any of the five succeeding years declare income not in accordance with it — that is, below the presumptive rate — two things follow:

1. You are ineligible for Section 44AD for five assessment years following the year of departure.
2. If your total income exceeds the basic exemption limit, you must maintain books under Section 44AA and have them audited under Section 44AB.

The second consequence is the one that surprises people. A loss-making or thin-margin year does not merely take you out of the scheme — it can pull you into a compulsory audit, in the very year your business did worst.

Consider the ordinary case. A trader uses 44AD for several years at 6%. In year four, margins compress and actual profit is 2% of turnover. Declaring the real figure is honest and correct — and it triggers the five-year bar plus, if income crosses the exemption limit, an audit obligation. Declaring 6% instead means paying tax on profit not earned.

Neither option is comfortable, and the decision should be made with the five-year consequence visible rather than discovered afterwards.

Why 44ADA is different

Section 44ADA has no equivalent of Section 44AD(4). A professional can use the presumptive basis one year and regular computation the next without triggering a bar.

That makes 44ADA a far lower-commitment election than 44AD. It is a genuine asymmetry between two provisions usually described together as though they were one scheme with different numbers.

When presumptive is the wrong choice

Even where you qualify, it is not automatically better:

• Your actual margin is well below the presumptive rate. Declaring 6% or 8% on a business genuinely earning 3% means paying tax on income you did not make. Over several years that comfortably exceeds the cost of maintaining books.
• You have losses to carry forward. The presumptive basis does not accommodate them, and a loss year handled this way forfeits relief you were entitled to.
• You expect to cross the limits soon. Electing into 44AD shortly before outgrowing it means facing the exit consequences early.
• You need proper financials anyway. Where a bank facility is contemplated, prepared or audited accounts will be required regardless — see CMA data for bank loans. A presumptive return is a weak basis on which to approach a lender.
• Your margin is genuinely higher than the presumptive rate. Then presumptive is favourable and worth using — the scheme cuts both ways, and this is the case it was designed for.

The audit interaction

The link between presumptive taxation and audit is where most confusion sits.

Being within 44AD and declaring at or above the presumptive rate means no audit under 44AB for that activity, regardless of turnover up to the scheme limit.

Being outside it — because you exceeded the limit, or because you declared below the rate after having used the scheme — puts you back into the ordinary position, where the 44AB thresholds and the audit calendar apply, and in the 44AD(4) case the specific audit obligation bites.

This is why the presumptive decision and the audit decision cannot be taken separately. They are the same decision.

Which return, and by when

Presumptive income under 44AD or 44ADA is normally reported in ITR-4. Following the Finance Act 2026 amendment to Section 139(1), a non-audit ITR-3 or ITR-4 filer has a due date of 31 August of the assessment year — so 31 August 2026 for FY 2025-26 — rather than the 31 July date that applies to ITR-1 and ITR-2.

Where audit liability arises, the date moves to 31 October regardless of the form. Which form applies, and the deadline that follows from it, is set out in which ITR form applies to your business.

Under the Income-tax Act 2025

The 2025 Act consolidates the presumptive provisions into a single section, so the structure and the conditions attaching to each limb should be read against the new text for the years it governs rather than assumed to carry across unchanged. The section mapping guide covers the wider renumbering.

Where the business is trading rather than a trade, the turnover that decides all of this is not what the contract notes add up to — it is computed from the results. See how F&O and intraday turnover is actually worked out.

Limits and rates are stated for FY 2025-26 (AY 2026-27). Whether presumptive taxation suits a particular business depends on its actual margin, its plans and its history of electing the scheme, and should be assessed against them before the return is filed.
