A new flat late-fee structure for tax audit delays has been proposed — but it doesn't apply to this year's filings. Here's what actually governs Tax Audit Report compliance for AY 2026-27, and the deadlines you can't afford to miss.
Tax Audit Report Compliance for AY 2026-27 (FY 2025-26): What's Actually in Force
There's been some confusion around a proposed fixed late-fee structure for delayed Tax Audit Reports, so it's worth being precise about what applies this year. For Assessment Year 2026-27 (Financial Year 2025-26), the proposed fixed late fee of ₹75,000 / ₹1,50,000 — introduced under Section 428(c) of the new direct tax framework — does not apply. Compliance for this year continues to be governed entirely by the existing provisions of the Income-tax Act, 1961.
That's an important distinction, because it means the newer, harsher fixed-fee regime — ₹75,000 for delays up to one month, ₹1,50,000 for delays beyond that — simply isn't the law that applies to this year's Tax Audit Reports. What does apply is the existing penalty framework under Section 271B, which works differently.
The Penalty That Does Apply: Section 271B
Failure to submit the Tax Audit Report on time under Section 44AB continues to attract penalty proceedings under Section 271B. Unlike a flat fixed fee, this penalty is calculated as whichever is lower of the following two amounts:
- 0.5% of total sales, turnover, or gross receipts, or
- ₹1,50,000
For most small and mid-sized businesses, the 0.5%-of-turnover calculation will land well below ₹1,50,000, which means the penalty scales with the size of the business rather than hitting everyone with the same flat number. There's also a genuine escape route: penalty proceedings under Section 271B may be dropped entirely if a reasonable cause for the delay is demonstrated, as provided under Section 273B. That's not an automatic waiver — it requires actually making the case to the assessing officer — but it does mean a delay caused by genuine, demonstrable circumstances isn't necessarily fatal.
| Regime | Applies to AY 2026-27? | Structure |
|---|---|---|
| Proposed fixed late fee (Sec. 428(c), new framework) | No | Flat ₹75,000 / ₹1,50,000 |
| Section 271B (Income-tax Act, 1961) | Yes | Lower of 0.5% of turnover or ₹1,50,000, waivable for reasonable cause |
A Late Tax Audit Report Usually Means a Late Return Too — and That Has Its Own Costs
Because the Tax Audit Report deadline sits ahead of the Income Tax Return (ITR) deadline, a delay in one often cascades into a delay in the other. Two separate consequences follow from filing the ITR late:
Interest under Section 234A: Filing the ITR after the prescribed due date triggers simple interest at 1% per month (or part of a month) on the tax payable. This runs regardless of whether a Section 271B penalty is ultimately levied or waived — it's a separate, near-automatic consequence tied purely to the delay in filing the return.
Loss of the right to carry forward losses: This is often the more expensive consequence in practice. Under Section 80, read with Section 139(3), business losses, capital losses, and losses from owning and maintaining racehorses cannot be carried forward to future years if the ITR is filed after the due date. For a business that had a loss-making year and was counting on offsetting that loss against future profits, missing the deadline can permanently forfeit that benefit — there's no reasonable-cause exception available for this one the way there is for the Section 271B penalty.
Why this matters more than the penalty amount itself: A ₹1,50,000 penalty is a fixed, capped cost. A forfeited loss carry-forward has no cap — depending on the size of the loss and how many future years it could have offset, the real economic cost of a late filing can run far higher than any statutory penalty attached to the delay itself.
The Deadlines to Mark
- Tax Audit Report (Form 3CA-3CD / 3CB-3CD): 30th September 2026 — for cases not subject to transfer pricing reporting under Section 92E
- Income Tax Return (ITR): 31st October 2026 — for taxpayers whose accounts are required to be audited
The takeaway: the proposed ₹75,000/₹1,50,000 fixed late-fee regime does not apply to AY 2026-27 — Section 271B's turnover-linked penalty, subject to a reasonable-cause waiver, is what actually governs this year. But don't let that create a false sense of comfort: a delayed Tax Audit Report tends to delay the ITR as well, and that carries its own Section 234A interest and, more significantly, permanent loss of the right to carry forward business and capital losses. File the Tax Audit Report by 30th September 2026 and the ITR by 31st October 2026 to avoid both.
