Partnership Firm ITR Filing: Reasons for AY 2026-27

ITAI Blogger

August 13, 2026

A partnership firm must generally file an income tax return even when it has no taxable income, earns a loss, or has no tax payable. For AY 2026-27, covering income earned during FY 2025-26, the firm should file its return in ITR-5 and comply with the applicable audit and due date requirements.

Filing the partnership firm’s ITR protects the firm’s ability to carry forward losses, claim TDS refunds, support partner remuneration and interest deductions, maintain financial credibility, and respond to tax notices. This guide explains the key reasons to file a partnership firm’s ITR in AY 2026-27, filing requirements, due dates, tax audit rules, and common questions.

Is ITR filing mandatory for partnership firms in India?

Yes. Section 139(1) requires every partnership firm to file an income tax return, regardless of its income or loss. This requirement applies even when:

The firm has no taxable income.
The firm incurred a business loss.
The firm’s income is below the basic exemption limit.
The firm paid no advance tax.
The firm’s entire income was subject to TDS.
The firm opted for presumptive taxation under Section 44AD.
The firm did not conduct business during FY 2025-26 but remained active.

A partnership firm is taxed as a separate assessee. Its income does not get automatically included in the partners’ personal income tax returns. The firm must therefore report its income, expenses, assets, liabilities, tax deductions, TDS, and tax payable through its own return.

The Income Tax Department’s provisions on filing returns require firms to follow the return filing provisions applicable to them under Section 139.

Does this apply to a registered and unregistered partnership firm?

Yes. The filing obligation generally applies to both:

Registered partnership firms
Unregistered partnership firms

Registration under the Indian Partnership Act does not determine whether the firm must file an ITR. The firm’s status under income tax law and its business activities are more relevant.

An LLP is also generally required to file an income tax return, but it is legally different from a traditional partnership firm. Both commonly use ITR-5, subject to the applicable income tax return rules.

Reasons to file a partnership firm ITR in AY 2026-27

The following are the most important benefits and practical reasons for filing the return on time.

1. Filing is a statutory requirement under Section 139(1)

The primary reason is legal compliance. A firm cannot avoid filing merely because it has no tax payable.

Failure to file can result in:

Late filing fee under Section 234F
Interest for delayed payment of tax under relevant provisions
Loss of certain loss carry-forward benefits
Difficulty responding to notices
Greater scrutiny of unexplained transactions
Problems while applying for loans, tenders, registrations, or business contracts

A timely ITR creates a formal record of the firm’s business income and financial position for FY 2025-26.

2. Carry forward business loss in the partnership firm’s ITR

A partnership firm may incur a loss because of:

Low sales
High operating costs
Depreciation
Interest expenses
Partner remuneration
Business expansion
Start-up or closure costs

The firm should file the loss return within the prescribed due date to preserve the right to carry forward eligible business losses.

Under Section 72, eligible business losses can generally be carried forward and set off against eligible business profits in subsequent years, subject to the applicable conditions and time limit. A business loss is normally carried forward for up to eight assessment years.

For example:

A partnership firm incurs a business loss of ₹4,00,000 in FY 2025-26.
It files the return within the applicable due date for AY 2026-27.
The firm earns business profit in a later year.
It may use the eligible carried-forward loss against that future business income, subject to the Income Tax Act.

If the firm files the return late, Section 80 can restrict the carry-forward of certain losses, including business losses. Therefore, partnership firm ITR filing even with loss is important.

Unabsorbed depreciation follows separate rules and should not be confused with normal business loss.

3. Claim TDS refund through the firm’s ITR

Customers, companies, government departments, or other business clients may deduct tax at source from payments made to the partnership firm. The firm can claim credit for this TDS in its ITR.

A refund may arise when:

The firm’s actual tax liability is lower than the TDS deducted.
The firm incurred a loss during the year.
The firm received payments after TDS but had eligible expenses.
The firm paid advance tax in addition to TDS.
The firm’s income was lower than estimated.

The firm must check its TDS credit against Form 26AS and the Annual Information Statement before filing. Any mismatch should be reconciled with the deductor.

For example, if clients deduct ₹75,000 as TDS but the firm’s final tax liability is ₹40,000, the firm can claim the excess ₹35,000 as a refund through ITR-5.

This is one of the key reasons for partnership firm ITR filing for claiming TDS refund. The refund does not arise automatically merely because tax was deducted.

4. Support deduction for partner remuneration and interest

A partnership firm may claim deduction for:

Interest paid to partners
Remuneration paid to working partners

However, the partnership deed must authorise the payment, and the deduction must satisfy the limits and conditions under Section 40(b).

For FY 2025-26, interest to partners is generally deductible only up to 12% simple interest per annum, subject to the law and the terms of the partnership deed.

The deduction for remuneration to working partners is generally subject to limits based on book profit. The applicable limits include:

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 of book profit: 60%

The firm must record the remuneration and interest correctly in its books and report them in its ITR. The partners must separately report the remuneration and interest received from the firm in their individual returns.

A properly filed firm return helps establish that the payments were:

Authorised by the partnership deed
Actually paid or credited
Within the statutory limits
Correctly reflected in the firm’s accounts

5. Establish financial credibility

Banks, financial institutions, investors, suppliers, and government authorities often ask for ITR acknowledgements and financial statements.

A regular filing record can support:

Business loan applications
Cash credit and working capital limits
Overdraft facilities
Government tenders
Vendor registration
Commercial lease applications
Large purchase contracts
Visa or financial documentation for partners
Applications for business expansion

An ITR acknowledgement is stronger financial evidence than merely stating that the firm has income or turnover.

6. Avoid difficulties during tax notices and assessments

The Income Tax Department receives information from multiple sources, including:

TDS statements
GST returns
Form 26AS
Annual Information Statement
High-value transactions
Banking and financial institutions
Property and securities transactions

A partnership firm that does not file its ITR may receive a notice requiring it to explain its financial activity. Timely filing gives the department a return against which the firm’s reported transactions can be compared.

The firm should ensure that turnover, GST figures, TDS, bank receipts, partner transactions, and financial statements are consistent.

7. Meet compliance requirements for GST and other registrations

Income tax and GST are separate laws. GST registration does not replace income tax return filing.

However, the firm’s income tax return may be compared with:

GST turnover
E-invoice data
E-way bill information
TDS under GST
Bank receipts
Tax audit reports

Differences can be legitimate, such as GST-inclusive turnover, exempt supplies, advances, credit notes, or timing differences. The firm should maintain a reconciliation to explain such differences.

Partnership firm ITR filing requirements for AY 2026-27

A partnership firm should complete the following steps for AY 2026-27:

Maintain books of account and prepare the profit and loss account and balance sheet.
Calculate business income after considering allowable expenses, depreciation, partner remuneration, and interest.
Reconcile turnover with GST returns, bank statements, invoices, and accounting records.
Download and verify TDS information from Form 26AS and the Annual Information Statement.
Determine whether tax audit applies under Section 44AB.
Obtain the tax audit report, wherever applicable.
File the applicable return in ITR-5.
Pay self-assessment tax, if any, before filing.
Verify the return electronically through the firm’s registered account or other permitted method.
Preserve the acknowledgement, computation, audit report, financial statements, and supporting records.

Documents generally required

The firm should keep these details ready:

Permanent Account Number of the firm
Firm’s address and contact details
Partnership deed and amendments
Details of partners and their profit-sharing ratios
Profit and loss account
Balance sheet
Capital accounts of partners
Bank statements
GST returns and turnover details
TDS certificates and Form 26AS
Annual Information Statement
Details of fixed assets and depreciation
Details of loans and interest
Details of partner remuneration and interest
Tax audit report, where applicable
Details of brought-forward losses
Details of advance tax and self-assessment tax

The partnership deed is particularly important where the firm claims deduction for partner remuneration or interest.

Partnership firm ITR-5 filing due date for AY 2026-27

The standard due dates for FY 2025-26 and AY 2026-27 are generally as follows:

Category of partnership firm	ITR filing due date
Firm not liable to tax audit	31 July 2026
Firm liable to tax audit	31 October 2026
Firm requiring transfer pricing report in Form 3CEB	30 November 2026

The tax audit report is generally required before the ITR due date. For a firm liable to audit, the audit report is ordinarily due on 30 September 2026, while the ITR is due on 31 October 2026.

The Central Board of Direct Taxes can extend due dates through a notification or circular. Before filing, the firm should check the latest Income Tax Department e-Filing portal and the applicable CBDT notification.

A firm that files after the due date may face a late filing fee under Section 234F. The late filing fee can be up to:

₹5,000 where total income exceeds ₹5,00,000
₹1,000 where total income does not exceed ₹5,00,000

The firm may also have to pay interest if tax remains unpaid.

Partnership firm tax audit and ITR filing for AY 2026-27

A partnership firm may need a tax audit under Section 44AB when its business turnover or gross receipts cross the prescribed threshold.

For business, the general threshold is:

₹1,00,00,000, or
₹10,00,00,000 where cash receipts and cash payments do not exceed the prescribed 5% condition

The higher ₹10,00,00,000 threshold is subject to the statutory cash transaction conditions. Digital receipts alone may not be sufficient if the firm has other cash receipts or payments that breach the limit.

Tax audit may also apply in specific presumptive taxation situations, such as where the firm declares income below the presumptive rate and its total income exceeds the applicable basic exemption threshold.

The audit involves reporting information such as:

Turnover and gross receipts
Business expenses
Depreciation
Loans and deposits
Payments covered under tax deduction provisions
GST turnover
Related transactions
Partner payments
Specified financial transactions

The firm should not wait until the ITR filing deadline to determine audit applicability. An incorrect audit decision can affect both compliance and the return filing deadline.

Does presumptive taxation remove the need to file ITR?

No. A partnership firm eligible for presumptive taxation under Section 44AD must still file its income tax return.

Section 44AD generally applies to eligible businesses, subject to exclusions and conditions. The presumptive income is usually calculated at:

8% of eligible turnover or gross receipts
6% for eligible receipts received through specified banking or electronic modes

The turnover limit is generally:

₹2,00,00,000
₹3,00,00,000 where cash receipts do not exceed 5% of total turnover or gross receipts

The firm must verify its eligibility and comply with the relevant conditions for FY 2025-26. Choosing presumptive taxation changes the method of computing income; it does not cancel the partnership firm ITR filing requirement.

What happens if a partnership firm files ITR with a loss?

The firm should file a loss return by the original due date if it wants to carry forward eligible business losses.

A loss return can also help the firm:

Claim TDS or advance tax refund
Report unabsorbed depreciation
Establish the actual financial position
Maintain continuity of tax records
Reconcile losses with partner capital and business transactions
Support future loan or tender applications

The firm must distinguish between:

Business loss
Speculation business loss
Capital loss
Unabsorbed depreciation
Loss from other sources

Each category has different carry-forward and set-off rules. For example, a capital loss cannot generally be set off against normal business income in the same way as a business loss.

How is tax calculated for a partnership firm?

A partnership firm is generally taxed at a flat rate of 30%, along with applicable surcharge and health and education cess. The firm does not receive the individual basic exemption slab benefit in the same manner as an individual taxpayer.

Additional points include:

A surcharge may apply when total income exceeds the prescribed threshold.
Health and education cess applies at the statutory rate.
Alternate Minimum Tax provisions may apply in certain cases where the firm claims specified deductions.
The firm can claim eligible business expenses and depreciation.
Partner remuneration and interest must satisfy Section 40(b).

The firm should prepare a tax computation separately from its accounting profit because some expenses allowed in the books may not be deductible under the Income Tax Act.

Common questions about partnership firm ITR filing

Is ITR filing mandatory for a partnership firm with zero income?

Yes. A partnership firm generally must file its return even when it has zero taxable income or no business activity during the year.

Which ITR form applies to a partnership firm?

A partnership firm generally files ITR-5. The return is filed using the firm’s PAN and authorised signatory details.

Can a partnership firm file ITR after the due date?

Yes, a belated return may be filed within the time allowed under the law. However, late filing can result in a late filing fee, interest, and restrictions on carrying forward certain losses.

Can a partnership firm claim a refund without filing ITR?

No. The firm normally needs to file ITR-5 to claim a refund of TDS, advance tax, or self-assessment tax.

Do partners also need to file individual ITRs?

Yes, partners must independently assess whether they need to file their individual income tax returns. They must report taxable remuneration, interest, profit share, salary, capital gains, and other personal income as applicable.

A partner’s share of profit from a firm is generally exempt under Section 10(2A), but remuneration and interest received from the firm are generally taxable in the partner’s hands, subject to the applicable rules.

Is tax audit compulsory for every partnership firm?

No. Tax audit depends on turnover, gross receipts, cash transaction conditions, presumptive taxation provisions, and other statutory requirements. A firm should calculate its turnover and review the Section 44AB conditions before deciding whether an audit is required.

Practical example

ABC Traders is a partnership firm with the following figures for FY 2025-26:

Turnover: ₹1,40,00,000
Business expenses: ₹1,32,00,000
Profit before partner payments: ₹8,00,000
TDS deducted by customers: ₹1,20,000
Final tax liability after computation: ₹85,000

The firm should:

Determine whether tax audit applies based on turnover and cash transaction conditions.
Prepare its accounts and tax computation.
Report partner remuneration and interest only if authorised by the deed and within Section 40(b) limits.
File ITR-5 for AY 2026-27.
Claim credit for ₹1,20,000 TDS.
Claim a refund of the excess ₹35,000, subject to verification and processing.

If the same firm had incurred a loss instead of profit, it should still file ITR-5 to claim the TDS refund and preserve eligible loss carry-forward benefits.
