ITR-5 Filing for Audited Partnership Firms AY 2026-27

A partnership firm whose accounts are subject to tax audit must complete two separate compliances for FY 2025-26: upload the tax audit report and file ITR-5. For AY 2026-27, the usual tax audit report due date is 30 September 2026, while the income tax return filing deadline for an audited partnership firm is 31 October 2026. The firm must also ensure that its books, Form 3CD disclosures, partner remuneration, interest, TDS and GST figures reconcile before filing.

Filing of ITR5 by Partnership Firms Who Are Eligible for Audit in AY 26-27

A partnership firm, including a limited liability partnership where ITR-5 is applicable, generally files its income tax return using ITR-5. A firm cannot use ITR-4 because ITR-4 is not the prescribed return form for partnership firms.

The key compliance sequence is:

1. Determine whether the firm is liable to tax audit under Section 44AB.
2. Prepare and finalise the books of account and financial statements.
3. Appoint a Chartered Accountant to conduct the audit.
4. Upload the applicable tax audit report in Form 3CA or Form 3CB, along with Form 3CD.
5. Accept or reject the audit report through the firm’s income tax e-filing account.
6. Prepare and submit ITR-5.
7. Verify ITR-5 using the firm’s Digital Signature Certificate, wherever applicable.

The audit report and ITR-5 are separate filings. Uploading Form 3CD does not mean that the firm’s income tax return has been filed.

Section 44AB Audit Limit for Partnership Firm AY 2026-27

A partnership firm is generally liable to tax audit under Section 44AB in the following situations:

Nature of activity	Tax audit requirement for FY 2025-26
Business where cash receipts and cash payments do not satisfy the 5% condition	Turnover or gross receipts exceed ₹1,00,00,000
Business where aggregate cash receipts and cash payments are within the prescribed 5% limit	Turnover or gross receipts exceed ₹10,00,00,000
Specified profession	Gross receipts exceed ₹50,00,000
Presumptive taxation cases where the firm declares income below the prescribed presumptive income and the applicable conditions trigger audit	Audit may be required

The higher business threshold of ₹10,00,00,000 applies only when:

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

Account-payee cheques and account-payee bank drafts generally receive the treatment prescribed for non-cash transactions under the Income Tax Act. The firm should maintain a transaction-level review rather than assuming that all banking transactions automatically satisfy the 5% condition.

The statutory provisions relating to tax audit are available on the Income Tax Department website.

Example of the audit threshold

Suppose a partnership firm has business turnover of ₹8,00,00,000 during FY 2025-26. Its cash receipts are 3% of total receipts and cash payments are 4% of total payments. It may qualify for the higher ₹10,00,00,000 threshold, subject to satisfying all conditions.

If cash receipts are 7% of total receipts, the firm cannot use the higher threshold merely because its cash payments are below 5%. It must apply the normal ₹1,00,00,000 business turnover limit.

Audit under presumptive taxation

A partnership firm may be eligible for presumptive taxation in certain cases, such as business covered by Section 44AD or a specified profession covered by Section 44ADA. However, the firm must examine the consequences of declaring income below the prescribed presumptive amount or withdrawing from the presumptive scheme.

A firm that declares lower income and meets the conditions requiring maintenance of books and audit may need to obtain a tax audit report. This assessment should be made separately for each business or profession and not only by looking at total receipts.

ITR-5 Filing for Partnership Firms Liable to Tax Audit AY 2026-27

For a partnership firm subject to tax audit, ITR-5 must normally be filed by 31 October 2026 for AY 2026-27. The date applies to firms whose accounts are required to be audited and which do not have an international or specified domestic transaction requiring a transfer pricing report.

The compliance calendar is as follows:

Compliance	Normal due date for AY 2026-27
Completion and upload of tax audit report	30 September 2026
Filing of ITR-5 for an audited partnership firm	31 October 2026
ITR-5 where transfer pricing provisions apply	30 November 2026

These are the statutory due dates generally applicable for FY 2025-26. The Central Board of Direct Taxes may issue a separate notification extending a due date. Firms should verify any extension on the official income tax e-filing portal.

The tax audit report is normally required one month before the return filing deadline. Therefore, a firm should not wait until October to begin the audit process.

Form 3CA and Form 3CD for Partnership Firms AY 2026-27

The applicable tax audit report depends on whether another law already requires the firm to audit its accounts.

When is Form 3CA applicable?

Form 3CA applies when the firm’s accounts are already required to be audited under another law. The prescribed report is filed along with Form 3CD, which contains detailed tax-related disclosures.

For example, if the firm is subject to a statutory audit under a law other than the Income Tax Act, the auditor may use Form 3CA with Form 3CD.

When is Form 3CB applicable?

Form 3CB generally applies when the firm is not required to get its accounts audited under any other law but becomes liable to tax audit under Section 44AB.

Form 3CB is also accompanied by Form 3CD. Form 3CD includes information such as:

• Accounting method followed by the firm
• Changes in the method of accounting
• Tax depreciation and depreciation as per books
• Disallowances under Section 40(a), Section 40(b), Section 40A(3) and other provisions
• Payments covered by TDS provisions
• GST registration and indirect tax details
• Loans, deposits and specified transactions
• Partner remuneration, commission, bonus and interest
• Particulars of related parties and specified domestic transactions
• Quantitative details, where applicable

The Chartered Accountant uploads the report electronically using the applicable form. The partnership firm must then log in to its e-filing account and respond to the audit report. The return filing process should use the final figures reported in the signed audit report.

Tax Audit Report Due Date for Partnership Firm AY 2026-27

The tax audit report due date for a partnership firm for AY 2026-27 is generally 30 September 2026. The audit report must be furnished electronically by the Chartered Accountant through the income tax e-filing portal.

The firm should complete the following steps before the audit report is uploaded:

1. Finalise the trial balance and ledger accounts.
2. Reconcile turnover with GST returns, invoices and bank receipts.
3. Verify cash receipts and payments for the 5% threshold.
4. Check partner capital accounts and drawings.
5. Calculate allowable partner remuneration and interest.
6. Review TDS returns, Form 26AS and Annual Information Statement data.
7. Identify disallowances under Section 43B and other relevant provisions.
8. Reconcile depreciation in the books with depreciation under the Income Tax Act.
9. Verify loans, deposits and cash transactions under Sections 269SS and 269T.
10. Approve the final financial statements and tax computation.

The firm’s authorised partner should ensure that the audit report is accepted on the e-filing portal. A report merely uploaded by the auditor may not complete the firm’s compliance if the firm does not take the required action on the portal.

How to File ITR-5 for Partnership Firm Subject to Audit

The online process for ITR-5 filing for an audited partnership firm is as follows:

Step 1: Prepare the firm’s tax computation

Calculate the firm’s total income after considering:

• Business or professional income
• Income from house property
• Capital gains
• Income from other sources
• Depreciation under the Income Tax Act
• Disallowable expenses
• Brought-forward losses
• Deductions available to the firm

A partnership firm is generally taxed at the applicable firm tax rate. Partner remuneration and interest are deductible only when they satisfy the conditions and limits under Section 40(b), the partnership deed and other applicable provisions.

Step 2: Confirm the partner details

ITR-5 requires information about the partners, including:

• Name and PAN
• Residential status
• Profit-sharing ratio
• Capital contribution
• Interest paid or credited
• Remuneration, salary, bonus or commission
• Profit allocation

The profit-sharing ratio in ITR-5 should agree with the partnership deed and the financial statements.

Step 3: Upload the tax audit report

The Chartered Accountant uploads:

• Form 3CA with Form 3CD, where another law requires audit, or
• Form 3CB with Form 3CD, where the audit arises only under Section 44AB.

The firm should review the report for errors before accepting it.

Step 4: Complete the ITR-5 schedules

The firm must fill the relevant schedules, such as:

• Profit and loss account
• Balance sheet
• Business or profession income
• Depreciation
• Partner remuneration and interest
• TDS and TCS
• Tax paid
• Brought-forward losses
• Minimum Alternate Tax or Alternate Minimum Tax, where applicable
• Foreign assets or income, if relevant
• GST turnover details, where required

Step 5: Validate and submit the return

After validating all schedules, upload the return through the e-filing portal. The return must be verified in the prescribed manner, normally using the firm’s DSC where digital signature verification is applicable.

The firm should download and retain:

• Acknowledgement number
• Filed ITR-V or electronic verification confirmation
• JSON or PDF copy of the return
• Tax audit report
• Computation of income
• Financial statements
• Working papers and reconciliations

Documents Required for Partnership Firm ITR-5 Filing AY 2026-27

A firm should provide its tax professional with the following documents:

Basic documents

• Firm PAN
• Partnership deed and amendments
• Registration certificates, if applicable
• Details of all partners
• Previous year’s ITR-5 and tax computation
• Income tax notices or orders received during the year
• Bank account details and a pre-validated account

Financial and accounting records

• Trial balance
• General ledger
• Profit and loss account
• Balance sheet
• Cash book and bank book
• Debtors and creditors ageing
• Fixed asset register
• Stock records and valuation details
• Partner capital and current account statements
• Details of loans and advances

Tax and transaction records

• GST returns, including GSTR-1 and GSTR-3B
• GST annual return, where applicable
• TDS and TCS returns
• Form 26AS and Annual Information Statement
• TDS certificates
• Advance tax and self-assessment tax challans
• Details of foreign remittances, if any
• Details of investments, capital gains and other income
• Details of cash receipts and payments
• Details of payments to partners and related parties

The firm should reconcile the turnover reported in the books with GST turnover. Differences may arise because of advances, exempt supplies, year-end adjustments, credit notes or transactions outside GST. Each difference should be documented.

Tax Treatment of Partner Remuneration and Interest

Partner remuneration and interest are common areas of error in audited partnership firm returns.

The firm should verify that:

• The partnership deed authorises payment of remuneration or interest.
• The payment follows the terms of the deed.
• The deed specifies the method or amount of remuneration.
• Interest does not exceed the permissible rate under Section 40(b).
• Remuneration is paid only to working partners where required by law.
• The amount claimed in the profit and loss account agrees with the amount disclosed in ITR-5 and Form 3CD.

From 1 April 2025, Section 194T requires tax deduction at source on certain payments such as salary, remuneration, commission, bonus or interest paid or credited by a firm to its partners, subject to the prescribed threshold and conditions. Firms should review the applicable TDS requirement for payments made during FY 2025-26 and reconcile the deduction with their TDS returns.

The firm should also check whether partner remuneration has been credited to the correct partner accounts and whether the corresponding income has been disclosed by the partners in their individual returns.

Common Mistakes in ITR-5 Filing by Audited Partnership Firms

1. Treating the tax audit report as the income tax return

Form 3CA or Form 3CB with Form 3CD is only the audit report. The firm must separately file and verify ITR-5.

2. Selecting the wrong return form

A partnership firm should generally use ITR-5. Using an individual return form can result in an invalid or defective return.

3. Mismatch between Form 3CD and ITR-5

Common mismatches include:

• Turnover
• Net profit
• Depreciation
• TDS
• Partner remuneration
• Partner interest
• GST turnover
• Tax audit clause details

The firm should compare the final ITR-5 with the signed audit report before submission.

4. Incorrect calculation of partner remuneration

A firm may claim remuneration based on an internal arrangement even though the deed does not authorise it or does not specify the calculation method. Such claims can be disallowed under Section 40(b).

5. Ignoring the cash transaction threshold

Firms claiming the ₹10,00,00,000 business audit threshold must maintain clear evidence supporting the 5% cash receipt and cash payment conditions.

6. Failing to report disallowances

Expenses may require disallowance because of:

• Late payment of statutory dues covered by Section 43B
• TDS non-compliance
• Excessive cash payments
• Payments to related parties
• Inadmissible partner payments
• Personal or non-business expenses

7. Not reconciling TDS credits

TDS claimed in ITR-5 should agree with Form 26AS and the Annual Information Statement. A mismatch can delay credit or create an outstanding demand.

8. Forgetting brought-forward losses

The firm must report brought-forward losses correctly and file the return within the prescribed deadline where timely filing is necessary to carry forward eligible losses.

9. Omitting tax payments

Advance tax, TDS, TCS and self-assessment tax should be entered using the correct challan details. The firm should verify BSR code, challan serial number, date and amount.

10. Missing final verification

An unverified return is not treated as properly completed. The authorised partner should complete verification promptly after submission.

What Happens If the Partnership Firm Files ITR-5 Late?

Late filing may result in:

• Late filing fee under Section 234F
• Interest under Section 234A for unpaid tax
• Interest under Sections 234B and 234C, where applicable
• Restriction on carrying forward certain losses
• Difficulty in claiming certain deductions or complying with tender and banking requirements
• Notices for mismatch or non-filing

The firm should also remember that failing to obtain or furnish a required tax audit report can attract a penalty under Section 271B. The penalty is generally linked to turnover or gross receipts and is subject to the statutory maximum, although reasonable cause may be considered under the law.
