Tax Audit 44AB is a key compliance requirement for businesses and professionals under the Income Tax Act. With the 2026 updates, taxpayers must also evaluate presumptive taxation (ITR-4) and new disclosure requirements carefully.
Income Tax Audit & Presumptive Taxation (ITR-4) – Updated Rules from April 2026
From April 1, 2026, significant changes have been introduced under the new Income Tax Act, 2025. Businesses and professionals must now clearly understand whether to opt for tax audit (Section 44AB / Section 63) or presumptive taxation (ITR-4).
Choosing the right method impacts your compliance cost, tax liability, and risk of notices. Proper planning helps avoid unnecessary audit burden while staying fully compliant.
Tax Audit Requirement – Section 44AB (Now Transitioning to Section 63)
Under the new Income Tax Act, 2025, Section 44AB is being restructured into Section 63 to simplify audit compliance and reporting.
- Ensures correctness of income and deductions
- Verifies compliance with tax provisions
- Reduces chances of scrutiny
- Improves financial credibility
Applicability of Tax Audit (FY 2025-26 / AY 2026-27)
| Category | Threshold |

| Business | ₹1 Crore (₹10 Crore if 95% digital) |
| Profession | ₹50 Lakhs |
| Presumptive Cases | If profit declared below limits |
Presumptive Taxation – Simplified Tax Filing (ITR-4)
Presumptive taxation allows small businesses and professionals to avoid detailed books and audit requirements by declaring fixed percentage income.
- Business (44AD): Turnover up to ₹2–3 Crore
- Profession (44ADA): Receipts up to ₹75 Lakhs
- Profit: 6% / 8% (business), 50% (profession)
New Rule from April 2026 – Mandatory Disclosure in ITR-4

Earlier, presumptive scheme avoided detailed reporting. Now, transparency is increased to reduce misuse and mismatch with AIS.

Frequently Asked Questions – Tax Audit & Presumptive Taxation
What is the fees for Income Tax Audit?
Tax audit fees generally start from ₹10,000 to ₹25,000 for small businesses. The cost may increase based on turnover, number of transactions, GST reconciliation, and complexity of accounts.
What is the cost for presumptive taxation (ITR-4 filing)?
Presumptive taxation filing (ITR-4) is more cost-effective and typically ranges from ₹3,000 to ₹7,500 depending on business details, disclosures, and asset reporting requirements.
Which is better – Tax Audit or Presumptive Taxation?
Presumptive taxation is suitable for small businesses to reduce compliance cost. However, if your actual profit is lower than prescribed limits, tax audit may be beneficial to reduce tax liability legally.
What are the new changes in ITR-4 from April 2026?
Under the new rules, taxpayers opting for presumptive taxation must disclose asset details, investments, bank balances, and financial position in ITR-4. This increases transparency and reduces mismatch with AIS data.
