Presumptive taxation is the closest thing India's income tax law offers to a shortcut for small taxpayers — declare a fixed share of turnover or receipts as income, skip the detailed bookkeeping, and, within limits, skip the audit too. For nearly a decade, that shortcut lived across three separate provisions — Sections 44AD, 44ADA and 44AE. From this year, all three sit inside a single section of India's new Income-tax Act, 2025. The rules haven't changed much. The address has.

The Three Schemes at a Glance

The substance of each scheme is unchanged — only the citation moves. Section 58 organises the three categories as a table with three serial numbers, rather than three standalone sections:

One Year, Two Rulebooks

Here's the wrinkle worth flagging before anything else. Right now, in the middle of AY 2026-27 filing season, you're still working under the old numbers. Income earned in FY 2025-26 is assessed entirely under the Income-tax Act, 1961 — so your return will (correctly) cite Section 44AD, 44ADA or 44AE, not Section 58.

The Income-tax Act, 2025 came into force on 1 April 2026, but it governs income earned from FY 2026-27 onwards — what the new Act calls a "Tax Year" rather than a "Previous Year" or "Assessment Year". That means the business income you're earning right now already falls under the new Section 58 framework, even though the return you're about to file for last year still uses the familiar old sections. Two rulebooks, one overlapping year — worth keeping straight, especially if you're pencilling in next year's advance tax.

The Fine Print: When "Presumptive" Isn't Optional

Presumptive taxation isn't purely a taxpayer's choice once you're in it. If you declare profit below the deemed rate — say, a business with ₹90 lakh turnover reports only ₹4 lakh in actual profit, well under the 8% (₹7.2 lakh) presumptive figure — and your total income for the year, from all sources, exceeds the basic exemption limit (₹4 lakh under the new tax regime, ₹2.5 lakh under the old regime), the benefit of skipping books and audit disappears. Regular books of account and a tax audit under Section 63 (old Section 44AB) become mandatory instead. Many taxpayers assume opting in guarantees no audit, ever — it only guarantees no audit if you stick to, or beat, the deemed rate.

There's also a five-year lock-in to factor in. Once you use presumptive taxation for a business in a given year, declaring profit below the prescribed rate in any of the following five years costs you access to the scheme for that business for the five years after that — pushing you back onto books and audit for the lock-out period too, if income exceeds the exemption limit. It rewards consistency and can penalise a single bad year.

A Few Things Still Being Worked Out

As with any large-scale renumbering exercise, a handful of questions are still being debated among tax professionals. One recurring one: where a taxpayer runs more than one business, or carries a loss under another head of income, exactly how far the bar on setting off "other losses and deductions" against presumptive income extends isn't entirely settled. Until the department issues clearer guidance, this is exactly the kind of situation where a quick conversation with your CA before filing is worth more than a general rule of thumb.

Is It Right for You?

Presumptive taxation tends to make the most sense when your actual margin runs close to or above the deemed rate, when you'd rather skip the cost of maintaining full books, or when a full audit would be disproportionate to the size of your operation. It's less attractive if your real margins run persistently thin — a business genuinely earning 3–4% on turnover ends up taxed on a notional 6–8% instead, unless it's willing to take on books and audit to declare the lower, real number. And since moving in and out isn't free, it's worth deciding with next year in mind, not just this one.

How This Plays Out in Practice

Conclusion

Presumptive taxation remains one of the simplest ways for small businesses, professionals and transport operators to stay compliant without the overhead of full bookkeeping — that hasn't changed under the Income-tax Act, 2025. What has changed is where the rules live: three familiar sections have become one, wrapped in new terminology, even as this year's filing still runs on the old numbers. If you're unsure which rulebook applies to your return, or whether presumptive taxation still suits your actual margins, RNR & CO can walk through the numbers with you before you file.
