Section 44AB Tax Audit Limits for AY 2026-27

For AY 2026-27, a business generally becomes liable for a tax audit under Section 44AB when its turnover or gross receipts exceed ₹1 crore. This threshold increases to ₹10 crore where both cash receipts and cash payments do not exceed 5% of the relevant totals. For professionals, the standard tax audit limit remains ₹50 lakh, although the presumptive taxation limit under Section 44ADA can be ₹75 lakh if cash receipts stay within 5%.

This guide explains who is liable for tax audit under Section 44AB in AY 2026-27, how the ₹1 crore and ₹10 crore limits work, the rules for professionals and freelancers, the connection between Sections 44AD, 44ADA and 44AB, and the tax audit due date and Form 3CD requirements.

Who is liable for tax audit under Section 44AB in AY 2026-27?

A taxpayer may be liable for a tax audit if they carry on a business or profession and fall within any of the conditions prescribed under Section 44AB of the Income-tax Act, 1961.

The main cases are:

1. A business exceeds the applicable turnover limit.
2. A profession exceeds the applicable gross receipt limit.
3. A taxpayer using a presumptive taxation scheme declares income below the prescribed presumptive rate in specified circumstances.
4. A taxpayer becomes subject to audit after opting out of presumptive taxation under the applicable conditions.

The audit must be conducted by a practising chartered accountant. The auditor submits the audit report electronically in the prescribed form, generally Form 3CA or Form 3CB along with Form 3CD.

You can refer to the official text of Section 44AB on the Income Tax Department website for the statutory audit conditions.

Section 44AB tax audit limit for business AY 2026-27

₹1 crore tax audit limit for businesses

A person carrying on business must generally obtain a tax audit if their total sales, turnover or gross receipts exceed ₹1 crore during FY 2025-26.

The ₹1 crore limit applies where the taxpayer does not satisfy the special cash condition described below.

For example:

• Business turnover: ₹1,20,00,000
• Cash receipts: ₹10,00,000
• Cash receipts as a percentage of turnover: 8.33%

Since cash receipts exceed 5%, the taxpayer cannot use the higher ₹10 crore threshold. Because turnover exceeds ₹1 crore, the taxpayer is liable for tax audit under Section 44AB.

₹10 crore tax audit limit for businesses with low cash transactions

The tax audit threshold increases from ₹1 crore to ₹10 crore when:

• Aggregate cash receipts do not exceed 5% of total receipts; and
• Aggregate cash payments do not exceed 5% of total payments.

Both conditions must be satisfied. Meeting only one condition is not enough.

Example

A wholesaler has the following figures for FY 2025-26:

• Total turnover: ₹7,50,00,000
• Cash receipts: ₹15,00,000
• Total payments: ₹6,00,00,000
• Cash payments: ₹12,00,000

Cash receipts are 2% of turnover and cash payments are 2% of total payments. Since both percentages are within 5%, the taxpayer is not liable for tax audit merely because turnover exceeds ₹1 crore. The turnover would need to exceed ₹10 crore, assuming no other Section 44AB condition applies.

What counts as cash for the 5% test?

The taxpayer should examine the nature of receipts and payments carefully. The 5% test is not limited to physical currency placed in the cash book. Certain non-account-payee instruments may also be treated in the same manner as cash for this purpose.

Taxpayers should maintain clear records of:

• Cash sales and cash collections
• Cash purchases and expenses
• Payments through non-account-payee cheques or drafts
• Bank receipts and payments
• Digital and electronic transactions
• Customer advances and supplier advances, where relevant

A transaction should not automatically be treated as qualifying non-cash merely because it did not involve physical currency. The mode and statutory treatment of the transaction matter.

₹50 lakh tax audit limit for professionals in AY 2026-27

A person carrying on a specified profession must generally obtain a tax audit if their gross receipts exceed ₹50 lakh during FY 2025-26.

The ₹50 lakh professional limit applies to professions such as:

• Legal practice
• Medical practice
• Engineering
• Architecture
• Accountancy
• Technical consultancy
• Interior decoration
• Film artists
• Information technology professionals
• Other notified professions

For professionals, the ₹50 lakh tax audit limit under Section 44AB for AY 2026-27 continues to be the key audit threshold. The special ₹10 crore business threshold does not apply to professional receipts.

Does the ₹75 lakh limit replace the ₹50 lakh audit limit?

No. This is an important distinction.

Section 44ADA permits eligible professionals to declare presumptive income where gross receipts do not exceed:

• ₹50 lakh generally; or
• ₹75 lakh if cash receipts do not exceed 5% of total gross receipts.

However, the ₹75 lakh figure is a presumptive taxation eligibility limit, not a general tax audit limit under Section 44AB.

Example

A freelance software consultant has gross receipts of ₹60,00,000 and receives 95% of the amount through banking channels. The consultant may qualify for the Section 44ADA presumptive limit of ₹75 lakh, subject to all other conditions.

But if the consultant declares income below the presumptive rate and the applicable conditions under Section 44ADA and Section 44AB are triggered, a tax audit may still be required. Therefore, the ₹75 lakh limit does not provide a blanket exemption from tax audit.

₹1 crore or ₹10 crore tax audit limit under Section 44AB

The following table summarises the main business limits for AY 2026-27:

Situation	Tax audit turnover threshold
Cash receipts or cash payments exceed the permitted 5% condition	₹1 crore
Cash receipts and cash payments both remain within 5%	₹10 crore
Eligible business using Section 44AD	Presumptive taxation limits may apply separately
Specified profession	₹50 lakh gross receipts

The ₹10 crore limit is available only when both cash conditions are met. It is not a general ₹10 crore exemption for every business.

Also, turnover is not the only factor. A business with turnover below the applicable limit may still face audit requirements because of presumptive taxation provisions.

Tax audit exemption for businesses with cash receipts and payments up to 5% AY 2026-27

The law does not technically provide a complete tax audit exemption merely because cash receipts and payments remain within 5%. Instead, it raises the business audit threshold from ₹1 crore to ₹10 crore.

This means:

• Turnover up to ₹1 crore: ordinarily no audit based only on turnover.
• Turnover above ₹1 crore but up to ₹10 crore: no audit based on turnover if both 5% cash conditions are met.
• Turnover above ₹10 crore: audit generally applies under the turnover provision, even if cash transactions remain within 5%.
• Any separate presumptive taxation audit condition: may apply independently.

Example: business with ₹3 crore turnover

A trader has:

• Turnover: ₹3,00,00,000
• Cash receipts: ₹6,00,000
• Total payments: ₹2,40,00,000
• Cash payments: ₹9,00,000

Cash receipts are 2% of turnover and cash payments are 3.75% of total payments. The taxpayer can generally use the ₹10 crore threshold for the turnover-based audit test.

If the trader instead has cash payments of ₹20,00,000, cash payments would be 8.33% of total payments. The 5% condition would fail, and the ₹1 crore threshold would apply.

Presumptive taxation and tax audit under Sections 44AD and 44AB AY 2026-27

Presumptive taxation allows eligible taxpayers to calculate income at a prescribed percentage instead of maintaining detailed expense records in the usual manner.

Section 44AD for eligible businesses

Section 44AD generally applies to eligible resident individuals, Hindu Undivided Families and partnership firms, other than limited liability partnerships, carrying on eligible businesses.

The normal turnover limit under Section 44AD is ₹2 crore. This can increase to ₹3 crore where cash receipts do not exceed 5% of total gross receipts.

Under the scheme, income is generally presumed at:

• 8% of turnover or gross receipts for specified cash and other receipts; and
• 6% of turnover or gross receipts for eligible receipts received through account-payee instruments or prescribed electronic modes.

The taxpayer may declare a higher amount. However, declaring income below the presumptive amount can create tax audit and record-maintenance implications, depending on the taxpayer’s total income and the applicable Section 44AB conditions.

Section 44AD lock-in consequence

A taxpayer who opts for Section 44AD and later declares income contrary to the presumptive scheme may face restrictions on using Section 44AD in subsequent years. The law contains a five-year consequence in specified cases where the taxpayer does not continue with the presumptive scheme.

Therefore, a taxpayer should not choose between normal computation and Section 44AD only on the basis of the current year’s tax payable. The impact on future years also matters.

Section 44ADA for professionals

Section 44ADA applies to eligible professionals. Presumptive income is generally calculated at 50% of gross receipts.

The gross receipt threshold is:

• ₹50 lakh in the general case; or
• ₹75 lakh where cash receipts do not exceed 5% of total gross receipts.

If an eligible professional declares income below 50% and their total income exceeds the maximum amount not chargeable to tax, the provisions may require maintenance of books and a tax audit under the relevant Section 44AB condition.

The Income Tax Department’s guidance on presumptive taxation provides practical information on Sections 44AD and 44ADA.

Tax audit applicability for freelancers and professionals under Section 44AB

Freelancers do not automatically escape tax audit because they work independently or receive payments online. The correct treatment depends on the nature of the work, gross receipts, method of income declaration and presumptive taxation eligibility.

Freelancer with receipts below ₹50 lakh

A freelancer with gross receipts of ₹42,00,000 is generally outside the ₹50 lakh professional audit threshold. However, audit may still become relevant if the freelancer uses presumptive taxation but declares income below the statutory presumptive rate in circumstances covered by Section 44AB.

Freelancer with receipts above ₹50 lakh

A freelance consultant with gross receipts of ₹58,00,000 generally crosses the Section 44AB professional limit and must obtain a tax audit, subject to the precise nature of the activity and the applicable law.

The freelancer should separately check:

• Whether the activity qualifies as a specified profession
• Whether the receipts are business receipts or professional receipts
• Whether Section 44ADA applies
• Whether books of account are required
• Whether GST registration and GST return obligations also apply

Income-tax audit and GST compliance are separate matters. GST turnover thresholds, registration requirements and return obligations should not be confused with the Section 44AB income-tax audit limit.

Which forms are required for a Section 44AB tax audit?

The tax auditor generally submits one of the following reports:

Form 3CA with Form 3CD

Form 3CA applies where the accounts are already required to be audited under another law, such as company law or a similar applicable statute.

Form 3CB with Form 3CD

Form 3CB generally applies where the taxpayer’s accounts are not required to be audited under another law but the taxpayer is liable for income-tax audit under Section 44AB.

Form 3CD

Form 3CD contains detailed statements and tax particulars, including information about:

• Accounting methods
• Books of account
• Turnover and gross receipts
• Depreciation
• Disallowable expenses
• Loans and deposits
• TDS and other compliance matters
• GST-related details, where applicable
• Specified domestic and other tax reporting requirements

The taxpayer must provide accurate books, invoices, bank statements, expense records and other supporting information to the auditor. The auditor files the report electronically after obtaining the required details and confirmations.

The Income Tax Department’s e-filing portal contains the prescribed forms and filing-related guidance.

Tax audit due date and Form 3CD for AY 2026-27

For most taxpayers liable to tax audit, the tax audit report for FY 2025-26 must generally be furnished by 30 September 2026, one month before the income-tax return due date.

The usual timeline is:

Compliance	Due date for AY 2026-27
Tax audit report in Form 3CA/3CB with Form 3CD	30 September 2026
Income-tax return for a taxpayer subject to audit	31 October 2026
Transfer pricing report and applicable return cases	Separate extended dates may apply

Taxpayers involved in international or specified domestic transactions should check the separate transfer pricing reporting requirements. The tax audit due date and ITR due date may differ depending on the taxpayer’s category.

The taxpayer must accept or approve the audit report on the e-filing portal after the chartered accountant submits it. Failure to complete the taxpayer-side action can affect compliance even if the auditor has uploaded the report.

Penalty for failure to obtain or furnish a tax audit report

Section 271B may impose a penalty for failure to get accounts audited or furnish the audit report as required.

The penalty may be:

• 0.5% of total sales, turnover or gross receipts, or
• ₹1,50,000, whichever is lower.

A penalty may not apply where the taxpayer proves a reasonable cause under Section 273B. Taxpayers should retain evidence of circumstances such as serious illness, natural events, technical problems or other genuine causes that prevented timely compliance.

The Income Tax Department’s official penalty provisions should be checked for the applicable statutory language and current requirements.

Practical checklist for businesses and professionals

13. File the income-tax return by the applicable due date.

Frequently asked questions

Is tax audit required if business turnover is exactly ₹1 crore?

Generally, the turnover condition applies when turnover exceeds ₹1 crore. If the taxpayer satisfies the cash conditions, the higher ₹10 crore threshold may apply. Other presumptive taxation conditions can still create audit obligations.

Is tax audit required at ₹5 crore turnover if all payments are digital?

Not necessarily. The taxpayer must satisfy both conditions: cash receipts must not exceed 5% of total receipts and cash payments must not exceed 5% of total payments. If both conditions are met, the ₹10 crore threshold can apply.

Is the tax audit limit for professionals ₹75 lakh?

No. The general Section 44AB tax audit limit for professionals is ₹50 lakh. The ₹75 lakh figure is the enhanced Section 44ADA presumptive taxation limit where cash receipts do not exceed 5%.

Do traders qualify as professionals?

Usually, traders are treated as carrying on business, not a specified profession. Their relevant turnover threshold is generally ₹1 crore, or ₹10 crore if both 5% cash conditions are satisfied, subject to presumptive taxation provisions.

Does Section 44AD automatically remove the need for tax audit?

No. Section 44AD may simplify income computation for eligible businesses, but audit can become applicable where the taxpayer declares income below the presumptive rate or falls within another Section 44AB condition.

Can a company use the ₹10 crore tax audit threshold?

A company may use the turnover-based threshold if it satisfies the statutory conditions. However, its separate audit obligations under company law continue independently. Income-tax audit and statutory financial statement audit are different compliances.

Summary

For AY 2026-27, the main Section 44AB tax audit limit for business is ₹1 crore. It rises to ₹10 crore when both cash receipts and cash payments remain within 5%. The tax audit limit for professionals remains ₹50 lakh, while Section 44ADA may permit presumptive taxation up to ₹75 lakh where cash receipts do not exceed 5%.

Businesses, traders, freelancers and professionals should also review Sections 44AD and 44ADA before deciding that no audit is required. If liable, taxpayers should arrange the tax audit under Section 44AB for AY 2026-27, complete Form 3CA or Form 3CB with Form 3CD by 30 September 2026, and file the applicable return on time.
