Tax Audit Limits and Rules – Section 44AB of the Income Tax Act

If you are a freelancer, small business owner, or consultant, you have searched for the Section 44AA limit after hearing your CA say something like, "You are required to maintain proper books of accounts now." That sentence alone can create anxiety, especially if you thought filling ITR was enough. So let’s slow this down and understand section 44AA of the Income Tax Act in a way that actually makes sense in real life, not in exam language.

What is Section 44AB of the Income Tax Act?

Section 44AB of the Income Tax Act deals with the maintenance of books of accounts. In simple words, it specifies who is required to maintain books of accounts, what kind of books and from when, based on income turnover and profession.

This section applies to:

Businesses

Professionals

Freelancers

Consultants

But not everyone has to maintain books. That’s where limits come in.

Why Section 44AB Exists

‍The income tax department wants:

Proper income tracking

Verifiable expenses

Transparency in tax reporting

‍Without books:

Income can be underreported

Expenses can be inflated

Security becomes difficult

Section 44AB creates a clear threshold-based system: compliance is simple below the limit; compliance is required above it.

What Constitutes an Audit Report?

The tax auditor shall furnish his report, which is prescribed, which could be either from 3AB Where:

From no. 3CA is furnished when a person is carrying on a business or profession is already mandated to get his accounts audited under any other law.

Form No. 3CB is furnished when a person carrying on business or profession is not required to get his accounts audited under any other law.

Section 44AB is About Who must Maintain Books.

A very important clarification:

Section 44AA does not talk about tax audits

It talks only about the maintenance of books of accounts.

Audit comes later under Section 44AB.

Who is Liable to Maintain Accounts as per Section 44AB?

This is one of the most searched questions:

Who is liable to maintain accounts as per section 44ab

The answer depends on:

Whether you are in a specified profession

Or a non-specified profession/business

Section 44AA (1) Specified Professions

Section 44 AA of the Income Tax Act applies to specified professionals.

If you belong to a specified profession:

You must maintain books of accounts irrespective of income. No threshold, no escape.

List of Specific Professions Under Section 44 AB

Here is the official list of specified professions under section 44AB(1):

Legal (advocates, lawyers)

Medical (doctors, surgeons)

Engineering

Architectural

Accountancy (CAs)

Technical consultancy

Interior decoration

Any other profession will be notified later

If you fall in this list, books of accounts are mandatory, even if the income is 2 Lakh.

What Books Are Required for Specific Professions?

Specified professionals must maintain:

Cash book

Journal

Ledger

Copies of bills and receipts

Original bills for expenses above the prescribed limits

This requirement exists even if you opt for presumptive taxation later.

Section 44 AB Non-Specified Professions and Business

Now comes the part where limits matter.

‍Section 44AB(2) applies to:

Businesses

Non-specified professions

Freelancers not covered under 44AA(1)

Here, books are required only if income/turnover crosses limits.

Section 44AA Limit- The Core

Let’s answer the main query directly.

‍Section 44 AA Limit for specified Person

You are required to maintain books if:

Income exceeds 120000 or

Total sales/ turnover/gross receipts exceed 1000000

In any one of the three preceding financial years.

This is the classic 44 AA limit most people refer to.

What is the penalty for non-filing or delay in filing the Tax Audit Report?

If any taxpayer is required to get a tax audit done but fails to do so, the following may be levied as a penalty:

0.5% of the total sales, turnover, or gross receipts, or

Rs 1,50,000

However, if there is a reasonable cause of such failure, no penalty shall be levied under section 271B.

Courts for dealy in filing tax audit reports are:

Natural Calamities

Resignation of the Tax Auditor and Consequent Delay

Resignation of Accountant/key employees.

Section 44 AB Limit for AY 2025-26

Many people specifically search:

44 aB limit for AY 2026

As of Now:

‍The limits remain unchanged

Income limit: ₹120,000

Turnover limit: ₹10,00,000

Until the law is amended, these thresholds continue to apply for AY 2025–26.

Important Point About Likely to Exceed

Section 44 AA also applies if:

Income is likely to exceed 120000

This means:

Even if the current-year income is lower

But expected to cross the limit

Books should be maintained proactively

Waiting till year-end can be risky.

Does Section 44AB Apply to Companies?

Another common question:

Section 44 AB applies to companies

Technically:

Companies are already required to maintain books under companies act.

So, section 44 AB is practically irrelevant for companies.

Section 44 AB is mainly relevant for:

Individuals

HUFs

Firms

LLPs

Section 44 AA Vs Section 44 AB- Don't confuse Them

Section	Purpose
Section 44AA	Maintenance of books
Section 44AB	Tax audit requirement

What of You are Under Presumptive Taxation?

This is a very common confusion

Business Under Section 44 AD

If you opt for 44AD

And declare income as per the presumptive rate

Then, books under Section 44AB may not be required

Profession Under Section 44ADA

Even under 44ADA

Specified professionals must still maintain basic records

Presumptive does not always override 44AB.

Maintenance of Books Of Accounts as per the Income Tax Act: Practical Meaning

Maintaining books doesn’t mean:

Complex accounting software

Daily journal entries by hand

It means:

Clear income records

Expense proof

Bank reconciliation

Logical documentation

The goal is verifiability, not paperwork burden.

What Happens if You Don’t Maintain Books When Required?

Failure to comply can lead to:

Penalty under Section 271A

Difficulty during scrutiny

Disallowance of expenses

Higher tax liability

Many notices start simply because books are missing.

Common Misunderstanding About Section 44 AA

Let’s clear some myths:

Only big business needs books

Freelancers don’t need books

Bank statements are enough

If the audit is not applicable, the books are not required

All of these are wrong in many cases

Practical Examples to Understand Section 44 AB

‍Eg 1: Freelancer

Income: 2.5 lakh

Turnover: 8 lakh

Income exceeds 1.2 lakhs, books required

‍Eg 2: Small Trader

Turnover: 2Lakhs

Turnover exceeds 10 lakhs

How Long Should Books Be Maintained?

Books should generally be preserved for:

6 years end of the relevant assessment year, longer if:

Assessment is pending

Litigation is ongoing

Best Practices for Complying With Section 44AA

If you are close to the limit:

Start basic bookkeeping early

Maintain digital records

Keep invoices and receipts

Reconcile bank statements

Review income projections quarterly

Compliance is easier than correction.

Section 44 AB in One Simple Line

If we had summarised the section 44 AA limit in one sentence:

Section 44 AA decides whether you must maintain books of accounts, based on your profession and income/ turnover limits.

Why Section 44 AB is More Important Than People Think

Most tax disputes don’t start with tax rates; they start with:

Lack of records

Incomplete books

Unexplained income

Section 44AB is the first line of defence in such cases.

Final Thoughts

Section 44 AB of the Income Tax Act is not meant to scare taxpayers. It exists to:

Encourage record-keeping

Reduce disputes

Support genuine taxpayers

Once you understand the limits and applicability, compliance becomes routine—not stressful.

As per the Income Tax 1961 Act of audit is mandatory for businesses exceeding a certain turnover limit to ensure compliance with the law. An understanding of the provisions can be helpful to avoid penalties.
