ITR-5 Filing for Partnership Firm AY 2026-27

ITAI Blogger

August 17, 2026

A partnership firm must file its income tax return in ITR-5 for AY 2026-27 if it earned income or carried on business during FY 2025-26. The return covers income from 1 April 2025 to 31 March 2026. The applicable due date depends mainly on whether the firm is required to obtain a tax audit under Section 44AB of the Income-tax Act, 1961.

For most partnership firms, the key dates are 30 September 2026 for non-audit cases and 31 October 2026 for tax-audit cases, unless the Central Board of Direct Taxes (CBDT) announces an extension. This guide explains the ITR-5 filing for partnership firm AY 2026-27, tax calculation, documents, presumptive taxation, online filing process, validation errors and e-verification.

ITR-5 filing by a partnership firm in AY 2026-27

A partnership firm, including a limited liability partnership (LLP), generally files its return using ITR-5. ITR-5 is applicable to firms, LLPs, Association of Persons, Body of Individuals and certain other entities that are not eligible to use ITR-1, ITR-2, ITR-3 or ITR-4.

The firm must file ITR-5 even if:

It has no taxable income.
It incurred a loss.
It claimed deductions that reduced its taxable income to nil.
It opted for presumptive taxation.
It was registered during FY 2025-26 but had no business activity, subject to applicable filing requirements.

A partnership firm cannot use ITR-4 because ITR-4 is designed for eligible individuals, Hindu Undivided Families and firms other than LLPs that satisfy specific conditions. In practice, a firm should use ITR-5 where the return requires detailed reporting of partners, partner remuneration, profit-sharing ratios, balance sheet information or audit details.

The return for FY 2025-26 is governed by the provisions applicable for AY 2026-27 under the Income-tax Act, 1961.

Partnership firm ITR-5 due date AY 2026-27

The due date for partnership firm income tax return filing depends on tax-audit and transfer-pricing requirements.

Type of partnership firm	ITR-5 due date for AY 2026-27	Tax audit report due date
Firm not required to obtain tax audit	30 September 2026	Not applicable
Firm required to obtain tax audit under Section 44AB	31 October 2026	Generally 30 September 2026
Firm requiring a transfer pricing report under Section 92E	30 November 2026	Report under Section 92E generally due by 31 October 2026

The tax audit report is filed electronically in Form 3CA or Form 3CB, along with Form 3CD, before the income tax return is filed.

These are the statutory dates applicable to AY 2026-27. Check the Income Tax Department e-filing portal for any CBDT notification extending a due date.

When does a partnership firm need a tax audit?

A partnership firm usually requires a tax audit if its business turnover or gross receipts exceed the applicable Section 44AB threshold.

For a business:

The general turnover threshold is ₹1,00,00,000.
The threshold increases to ₹10,00,00,000 where cash receipts do not exceed 5% of total receipts and cash payments do not exceed 5% of total payments.
The enhanced threshold does not apply if the firm has significant cash receipts or cash payments.

For a profession:

The general gross receipts threshold is ₹50,00,000.

A tax audit may also become relevant where the firm declares profits lower than the presumptive income under Sections 44AD or 44ADA and its total income exceeds the basic exemption limit applicable to the firm.

How to calculate partnership firm tax for AY 2026-27

A partnership firm is taxed separately from its partners. The firm pays tax on its taxable income, while the partner’s share of profit from the firm is generally exempt in the partner’s hands under Section 10(2A).

Tax rate for a partnership firm

For AY 2026-27, the basic income tax rate for a partnership firm is generally:

30% of taxable income
12% surcharge where total income exceeds ₹1,00,00,000
4% Health and Education Cess on income tax plus surcharge

This results in an effective rate of:

31.20% where surcharge does not apply
34.944% where 12% surcharge applies

A partnership firm does not choose between the old and new tax regimes in the same manner as an individual taxpayer. The individual new tax regime and rebate changes do not automatically alter the basic tax rate applicable to partnership firms.

Allowability of partner remuneration and interest

The firm can claim a deduction for partner remuneration and interest only if the partnership deed authorises the payment and the conditions under Section 40(b) are satisfied.

Interest paid to partners is generally deductible up to 12% simple interest per annum.

The allowable deduction for working partners’ remuneration is calculated as follows:

Book profit	Maximum deductible remuneration
On the first ₹6,00,000 of book profit or in case of loss	₹3,00,000 or 90% of book profit, whichever is higher
On the balance book profit	60%

For example, if the firm has book profit of ₹10,00,000:

First ₹6,00,000: 90% equals ₹5,40,000
Balance ₹4,00,000: 60% equals ₹2,40,000
Maximum deductible remuneration: ₹7,80,000

The deed should clearly identify the working partners and specify the method or amount of remuneration. A vague clause may result in disallowance.

The Income Tax Department’s tax laws database contains the relevant provisions, including Sections 10(2A), 40(b), 44AB and 139.

Presumptive taxation for partnership firm ITR-5 AY 2026-27

A resident partnership firm, other than an LLP in the case of Section 44AD, may be eligible for presumptive taxation. Under this method, the firm declares a prescribed percentage of turnover or receipts as income instead of claiming detailed business expenses.

Section 44AD for eligible businesses

Under Section 44AD:

Presumptive income is generally 8% of turnover or gross receipts.
Presumptive income can be 6% for qualifying receipts received through banking channels or prescribed electronic modes.
The turnover limit is generally ₹2,00,00,000.
The limit increases to ₹3,00,00,000 where cash receipts do not exceed 5% of total turnover or gross receipts.

Section 44AD does not apply to specified professions, commission or brokerage income, agency businesses and certain other businesses.

A partnership firm opting for Section 44AD cannot separately claim deductions for business expenses, depreciation, partner salary or partner interest from the presumptive income. However, the written-down value of depreciable assets is calculated as if depreciation had been allowed.

Section 44ADA for specified professions

A resident partnership firm other than an LLP may be eligible for Section 44ADA where it carries on a specified profession, such as legal, medical, architectural, accountancy, technical consultancy or an approved profession.

The presumptive income is generally 50% of gross receipts. The gross-receipts threshold is:

₹50,00,000 generally
₹75,00,000 where cash receipts do not exceed 5% of total gross receipts

The firm should verify whether its profession and legal structure qualify before selecting the presumptive option in ITR-5.

How to file ITR-5 online for partnership firm AY 2026-27

The firm can file ITR-5 through the income tax e-filing portal using the online form or the applicable offline utility.

Step 1: Log in to the e-filing portal

Visit the official income tax e-filing portal and log in using the firm’s PAN and password. Ensure that the firm’s PAN is active and that the authorised partner is correctly associated with the account.

Step 2: Select the return

Choose:

e-File
Income Tax Returns
File Income Tax Return
Assessment Year 2026-27
Status as firm
ITR form as ITR-5

Select FY 2025-26 as the relevant financial year when prompted.

Step 3: Complete general information

Enter or confirm:

Firm identification details
Nature of business
Partner details
Residential status
Filing section
Whether the firm is liable to audit
Details of the authorised partner

Use the partnership deed and accounting records to ensure that the partner names, PANs and profit-sharing ratios match.

Step 4: Report income and expenses

Enter income under the appropriate heads, including:

Profits and gains from business or profession
Income from house property
Capital gains
Income from other sources

For business income, enter turnover, expenses, depreciation, partner remuneration, partner interest and other relevant figures. The profit reported in ITR-5 should reconcile with the signed financial statements.

Step 5: Complete tax audit details

If the firm is liable to tax audit:

Confirm that the auditor has filed Form 3CA or Form 3CB and Form 3CD.
Enter the audit report acknowledgement number and date.
Report the relevant clauses from Form 3CD.
Ensure that the tax audit figures and ITR-5 figures agree.

Differences between turnover, depreciation, partner remuneration, GST turnover or tax payable can trigger notices or validation issues.

Step 6: Report tax payments and verify computation

Check:

TDS and TCS credits
Advance tax
Self-assessment tax
Interest under Sections 234A, 234B and 234C
Balance tax payable or refund

Pay any balance tax before submitting the return. The tax challan details should be entered correctly in the return.

Step 7: Submit and verify the return

Preview the return, correct errors and submit it. Complete e-verification within the prescribed time. The official ITR forms and instructions should be checked whenever the department releases the AY 2026-27 utility or updated schema.

Partnership firm ITR-5 validation errors

Validation errors commonly occur because of incorrect partner information, mismatched audit details or incomplete balance sheet schedules.

Common errors and solutions

1. Partner PAN or profit-sharing mismatch

Check that the PAN, admission date, retirement date and profit-sharing ratio match the partnership deed.

2. Remuneration exceeds the Section 40(b) limit

Recalculate book profit and apply the correct limit. The amount claimed in the profit and loss account may be higher than the amount allowed as a tax deduction.

3. Tax audit report details do not match

Confirm the audit report number, date, auditor membership number and figures in Form 3CD.

4. Balance sheet does not balance

Total assets must equal total liabilities and capital. Check partner capital accounts, loans, creditors, cash and bank balances.

5. TDS credit is not appearing

Check Form 26AS and AIS. Ask the deductor to file a corrected TDS statement if the credit is missing or incorrect.

6. Presumptive income is below the required percentage

Review whether the firm has selected Section 44AD or 44ADA correctly and whether digital and cash receipts have been classified accurately.

7. Bank account details are incomplete

Add at least one valid Indian bank account and nominate the account for refund, where applicable.

8. Negative values or missing schedules

Use the correct schedule for losses, depreciation, brought-forward losses and tax payments. Do not enter negative values where the utility requires zero or a separate loss schedule.

Partnership firm ITR-5 e-verification process AY 2026-27

The firm must verify the filed return. An unverified return is generally treated as invalid.

A partnership firm can use the applicable verification method available on the portal, such as:

Digital Signature Certificate of the authorised partner, where DSC verification is mandatory or selected
Electronic verification through an eligible bank account or demat account
Electronic verification through other methods enabled for the entity on the e-filing portal

For tax-audit cases, filing through DSC is generally required. The authorised partner should ensure that the DSC is registered on the portal and that the emSigner utility, DSC token and certificate are functioning correctly.

DSC troubleshooting

If DSC verification fails:

Register or re-register the authorised partner’s DSC.
Install the latest emSigner utility.
Check that the DSC is valid and not expired.
Confirm that the PAN in the DSC matches the authorised signatory’s PAN.
Use the correct USB token driver.
Retry verification from the filed return section.

After successful verification, download the acknowledgement and retain it with the firm’s tax records.

Practical tax calculation example

Suppose a partnership firm has the following figures for FY 2025-26:

Business receipts: ₹50,00,000
Business expenses excluding partner payments: ₹28,00,000
Depreciation: ₹2,00,000
Interest to partners: ₹1,20,000
Remuneration to working partners: ₹7,80,000

Book profit before partner interest and remuneration:

₹50,00,000 - ₹28,00,000 - ₹2,00,000 = ₹20,00,000

The firm must separately check the allowable deduction for interest and remuneration under Section 40(b). If the full amount is deductible, taxable business income becomes:

₹20,00,000 - ₹1,20,000 - ₹7,80,000 = ₹11,00,000

Tax calculation:

Income tax at 30%: ₹3,30,000
Health and Education Cess at 4%: ₹13,200
Total tax: ₹3,43,200

The firm must reduce TDS and advance tax credits from this amount and pay any remaining liability before filing ITR-5.
