Tax Audit Applicability Under Section 44AB

01. Understanding Section 44AB

It may be relevant to refer to para 5.18 and 5.20 of the Guidance Note on Tax Audit under Section 44AB of the Income-tax Act, 1961 (Revised 2026) by Direct Taxes Committee of the Institute of Chartered Accountants of India with ISBN No. : 978-93-47892-98-1

5.18 It may, however, be noted that in cases where the assessee carries on more than one business activity, the results of all business activities should be clubbed together. In other words, the aggregate sales, turnover and/or gross receipts of all businesses carried on by an assessee would be taken into consideration in determining whether the prescribed limit (Presently Rs. 1 crore and Rs. 10 crore for certain specified cases) as laid down in section 44AB has been exceeded or not. 

However, where the business is covered by section 44B or 44BBA, turnover of such business shall be excluded. Similarly, where the business or profession is covered by section 44AD or 44ADA or 44AE or 44BB or 44BBB and the assessee opts to be assessed under the respective sections on presumptive basis, the turnover thereof shall be excluded. So far as a partnership firm is concerned, each firm is an independent assessee for purposes of Income-tax Act. 

….

5.20 Under section 28(v), any interest, salary, bonus, commission or remuneration, by whatever name called, due to or received by, a partner of a firm from such firm shall be chargeable under the head profits and gains of business and profession. However, interest, remuneration, etc. received by an assessee from a partnership firm cannot be treated as gross receipt/turnover as partner is not doing any business/profession independently, but it is the firm which is carrying on the business/profession, in which assessee is only a partner.(Perizad Zorabian Irani v PCIT, Mumbai – WP No. 1333/2021- Bombay High Court – dated 09.03.2022)

Section 44AB of the Income-tax Act, 1961 deals with the applicability of tax audit. While the provisions may appear straightforward at first glance, determining the correct clause under which tax audit becomes applicable can become tricky when an assessee carries on multiple businesses or professions.

The challenge becomes even more significant when presumptive taxation provisions under sections such as 44AD and 44ADA come into play.

For example, an entity may carry on 

• three different business activities and 
• two different professional activities. 

It is possible that the tax audit requirement may arise only for one business activity and one professional activity, while the remaining activities may not independently trigger the audit requirement.

02. The Five Clauses of Section 44AB

Section 44AB contains five clauses — (a) to (e) — dealing with different circumstances in which a tax audit may become applicable.

03. The Three Broad Triggers for Tax Audit

The triggers under Section 44AB can broadly be understood through three categories:

1. Turnover / gross receipts threshold — broadly covering clause (a) for business and clause (b) for profession.
2. Profit / loss in relation to presumptive taxation — primarily involving clauses (c) and (d).
3. Eligibility or non-eligibility for presumptive taxation — covered by clause (e).

Therefore, simply looking at turnover is not always sufficient. The first question should be whether there is a more specific presumptive-taxation-related provision that needs to be tested first.

04. Test Specific conditions Before General conditions

When more than one clause appears applicable, the law needs to be read as a whole. A practical approach is to test the more specific provisions first and move towards the general turnover-based provisions thereafter.

05. Presumptive Taxation: The Key to the Analysis

A major part of determining tax audit applicability is understanding presumptive taxation. For general business and professional activities, the relevant provisions include Section 44AD for certain businesses and Section 44ADA for certain professions.

• Section 44AE — business of operating heavy goods vehicles
• Section 44B — shipping business other than cruise shipping
• Section 44BB — business relating to exploration, etc., of mineral oils
• Section 44BBB — certain business of civil construction or related activities involving a foreign company

06. A Practical Elimination Approach

The theoretical provisions are important, but tax audit applicability ultimately needs to be determined while actually performing the tax audit work. A practical approach is therefore to use elimination.

1. Identify the assessee and the nature of each activity.
2. Identify the applicable presumptive taxation provisions.
3. Check whether the assessee is eligible for the relevant presumptive taxation scheme.
4. Test the specific provisions first.
5. Where relevant, compare actual profit with the prescribed presumptive profit requirements.
6. If the specific provisions do not trigger audit, test the applicable turnover or gross-receipts limits.
7. Consider cash receipt and payment conditions where relevant.
8. Determine the appropriate clause under which the tax audit requirement is applicable.

07. What Counts as a Profession?

The source refers to Section 44AA for determining what constitutes a profession. The listed professions include legal, medical, engineering, architectural, accountancy, technical consultancy and interior decoration.

It also refers to professions notified by the CBDT, including authorised representatives, company secretaries, film artists and several creative roles, as well as information technology.

The classification between business and profession is therefore an important preliminary step in determining the applicable tax audit provisions. Profession has been explicitly defined. Business is anything and everything that does not fall in ‘Profession’.

08. The Role of Cash Transactions

One of the important practical considerations discussed in the source is the condition relating to cash receipts and cash payments being within 5% of the respective cumulative totals.

09. Don’t Forget Multiple Activities

Tax audit applicability should not always be determined merely by looking at the assessee’s total turnover. The nature of each activity matters.

The source recommends capturing information activity-wise, including:

• Nature of activity
• Applicable section
• Type of person
• Residential status
• Turnover
• Profit
• Whether presumptive taxation is applicable
• Whether profit is above the presumptive taxation threshold

10. Practical Illustration: A Resident Individual with Multiple Activities

The source provides an illustration involving a resident HUF carrying on three businesses and two professional activities. The professional activities considered are Information Technology and Interior Decoration.

11. The Bigger Practical Lessons

The illustration demonstrates why tax audit applicability cannot always be determined using a single turnover figure.

• Different activities
• Different presumptive provisions
• Different conditions
• Different reasons for tax audit applicability

This is why an activity-wise analysis is so important. The final Tax Audit Report may require identification of the applicable clause, but the working behind that conclusion can involve testing multiple provisions.

12. Additional Practical Points

Presumptive taxation should be tested carefully

The applicability of presumptive taxation depends on the nature of the activity, type of assessee, residential status and other prescribed conditions.

Turnover should be calculated appropriately

The source specifically notes that while calculating turnover, turnover relating to activities covered by clauses (e), (c) and (d) should be reduced where income is offered under the applicable presumptive taxation scheme.

Exempt income does not necessarily eliminate tax audit obligations

The source also refers to the CBDT view that exemption of income under certain provisions of Section 10 or Section 11 does not necessarily extend to the requirements relating to maintenance of books under Section 44AA or audit under Section 44AB.

Certain activities are treated as business

The source gives examples including:

• Advertising agents
• Clearing, forwarding and shipping agents
• Couriers
• Insurance agents
• Nursing homes
• Stock and share broking / dealing
• Travel agents

13. A Simple Framework for Tax Audit Applicability

14. Conclusion

Determining tax audit applicability under Section 44AB is not simply a matter of comparing turnover with a threshold.

Where an assessee has multiple businesses or professions, the analysis can involve several layers — nature of activity, presumptive taxation, eligibility, profit percentage, turnover, cash transactions and the specific provisions applicable to each activity.

The illustration also demonstrates an important point: tax audit can become applicable to different activities of the same assessee for completely different reasons.

A structured, activity-wise approach makes the analysis clearer, more consistent and easier to document.
