Income Tax Return for Partnership Firm (2026 Guide)

Income Tax Return for Partnership Firm

A partnership firm files its income tax return as a separate taxpayer, at a flat 30% rate, before a single rupee of profit reaches the partners. There are no slabs and no basic exemption limit; tax applies to the firm's entire taxable income from the first rupee, and the firm files under its own PAN, not the partners'. This single structural fact is what trips up more business owners than anything else in this topic, and it's the reason income tax for a partnership firm looks nothing like income tax for an individual, freelancer, or sole proprietor.

This page sits inside the same cluster as our Income Tax Return guide, which covers ITR filing broadly across every taxpayer type. If you're looking specifically for how freelance or individual income tax works, our ITR Filing for Freelancers guide covers that separately, since a partnership firm's tax treatment, entity-level taxation, Section 40(b) limits on what partners can be paid, and its own distinct ITR form, is a genuinely different system, not a variation of the individual one.

Quick Answer: Income Tax for Partnership Firms

• The firm is a separate taxpayer. It computes its own taxable income and pays tax at a flat 30%, plus surcharge on income above Rs. 1 crore, plus 4% health and education cess.
• Which ITR form: partnership firms file ITR-5, using the firm's own PAN. There's no separate return form specifically for LLPs either, they also file ITR-5, with a field distinguishing the two entity types.
• Partner remuneration and interest paid by the firm are deductible for the firm, but only within limits set by Section 40(b), and are taxed as business income in the partner's own hands.
• A partner's share of profit from the firm is completely tax-exempt in their hands under Section 10(2A), since it was already taxed once at the firm level.
• Due dates: 31 July of the assessment year for firms not requiring a tax audit, 31 October for firms that do, and 30 November for firms with international or specified domestic transactions requiring transfer pricing disclosure. Extensions in a given year are common, so confirm the current deadline before filing.
• From FY 2025-26, Section 194T requires firms to deduct 10% TDS on remuneration, interest, and similar payments to a partner once aggregate payments to that partner exceed Rs. 20,000 in the year.

Why Partnership Firm Taxation Works Differently

Under Section 2(23)(i) of the Income Tax Act, a "firm" takes its legal meaning from the Indian Partnership Act, 1932: two or more people who've agreed to share the profits of a business carried on by all of them, or by any of them acting for all. For income tax purposes, though, that firm is treated as its own distinct assessee, entirely separate from the partners who own it.

This matters because it changes the order of operations. The firm computes total income, deducts allowable expenses including partner remuneration and interest within Section 40(b) limits, and pays a flat 30% tax on what remains. Only after that does anything reach the partners, and what they receive is split into two categories with very different tax treatment: remuneration and interest, which are separately taxable to the partner (since they were deducted, not taxed, at the firm level), and share of profit, which is fully exempt to the partner (since it was already taxed at the firm level, and taxing it again would be double taxation).

Which ITR Form Applies: ITR-5

ITR-5 is the form for partnership firms filing an income tax return for partnership firm purposes, along with LLPs, AOPs, BOIs, and a handful of other entity types. Individuals and companies use different forms entirely; a partner reporting their own remuneration and interest income personally files ITR-3, not ITR-5, since that income belongs to them individually, not to the firm.

ITR-5 requires:

• The firm's PAN, name, and registration details.
• Schedule BP, reconciling book profit from the profit and loss account to taxable business income, adding back expenses disallowed under Sections 40 and 40A.
• Partner-level disclosures: profit-sharing ratio, remuneration, interest on capital, and interest on loans for each partner, all cross-checked against Section 40(b) limits.
• The tax audit report (Form 3CA/3CB along with Form 3CD), where a tax audit applies.

A mismatch between what the firm's partnership deed authorises and what ITR-5 actually reports, for remuneration or interest specifically, is a common trigger for scrutiny, since the return and the underlying legal document are expected to tell the same story.

Section 40(b): What the Firm Can Actually Deduct for Partners

This is the provision that governs how much a firm can pay a working partner and still claim it as a deductible business expense, and it's the single most contested part of partnership firm taxation. It applies to two kinds of payments:

Remuneration (salary, bonus, commission) to working partners only, and only where the partnership deed specifically authorises it in writing. For FY 2025-26 (AY 2026-27), following the Finance Act 2024 revision that doubled the first-slab threshold, the deductible limit is:

• Rs. 3,00,000, or 90% of the first Rs. 6,00,000 of book profit, whichever is higher, plus
• 60% of book profit beyond Rs. 6,00,000.

If the firm has a loss for the year, the maximum deductible remuneration is capped at Rs. 3,00,000 regardless.

Interest on capital contributed by a partner, capped at 12% per annum, simple interest. If the deed permits a higher rate, only the first 12% is deductible, the excess is disallowed for the firm (though the partner is still taxed on the full amount received). If the deed is silent on interest entirely, no interest deduction is available at all.

It's important to understand that Section 40(b) is a disallowance provision, not a hard payment cap. A firm can legally pay a partner more than these limits; it simply can't deduct the excess. That excess still gets taxed twice in practical effect, once because the firm can't reduce its taxable income by that amount, and again because the partner is taxed on the full amount they actually received. Staying within the Section 40(b) ceiling is what keeps remuneration tax-efficient for both sides.

How Partners Are Taxed on What They Receive

• Remuneration and interest on capital, credited or paid to a partner, are taxed in the partner's hands as business income under Section 28(v), reported on the partner's own ITR-3, not the firm's ITR-5.
• Share of profit, whatever's left after the firm pays its own 30% tax, is fully exempt in the partner's hands under Section 10(2A), regardless of how large that share is.

This split is what keeps the overall system from taxing the same rupee twice under normal circumstances: profit share is taxed once, at the firm level; remuneration and interest are taxed once, at the partner level, having been deducted (not taxed) at the firm level.

Section 194T: TDS on Partner Payments (New From FY 2025-26)

This is a recent addition worth flagging specifically, since it changes a compliance step firms didn't previously have to think about. Section 194T requires a firm, including a partnership firm or LLP, to deduct 10% TDS on salary, remuneration, commission, bonus, or interest paid to a partner, once the aggregate of such payments to that individual partner crosses Rs. 20,000 in the financial year. The TDS deducted shows up in the partner's own Form 26AS and AIS, and is claimed as a credit against their personal tax liability when they file ITR-3. This is a firm-level compliance obligation layered on top of the Section 40(b) deduction rules, not a replacement for them, both apply simultaneously.

Presumptive Taxation for Partnership Firms

Partnership firms (not LLPs) can opt for presumptive taxation under Section 44AD, the same provision available to individual businesses, declaring 6% of turnover (digital receipts) or 8% (cash receipts) as taxable income, up to the applicable turnover threshold, without maintaining full books or facing a tax audit.

There's a detail specific to firms here that's easy to miss: under Section 44AD(2), once presumptive income is computed, no further business deduction is allowed except for partner remuneration and interest within Section 40(b) limits. Every other expense a firm would normally deduct, rent, salaries to staff, depreciation, is already deemed to be built into the presumptive percentage and can't be claimed separately. Partner remuneration and interest are the one specific carve-out still deductible from presumptive income, which makes getting the Section 40(b) calculation right just as relevant for a firm on presumptive taxation as for one maintaining full books.

When a Tax Audit Applies

A partnership firm needs a tax audit under Section 44AB if:

• Business turnover exceeds Rs. 1 crore (extended to Rs. 10 crore where cash receipts and cash payments each stay within 5% of total transactions).
• Professional gross receipts exceed Rs. 50 lakh.
• The firm declares income below the presumptive percentage under 44AD while total income exceeds the basic exemption threshold that would otherwise apply, though since the firm itself has no basic exemption, this specific trigger works somewhat differently for firms than for individuals, and is worth confirming with a professional based on the firm's specific numbers.

Where an audit applies, Form 3CA or 3CB, along with Form 3CD, has to be filed alongside ITR-5, and the due date shifts from 31 July to 31 October accordingly.

ITR-5 Due Dates for Partnership Firms

• 31 July of the assessment year, for firms not requiring a tax audit.
• 31 October, for firms requiring a tax audit under Section 44AB.
• 30 November, for firms with international or specified domestic transactions requiring Form 3CEB (transfer pricing) disclosure.

Government extensions to these dates happen fairly often in practice, so it's worth confirming the current year's actual deadline on the income tax portal rather than assuming the statutory date holds without change. Filing late doesn't just add interest and a late fee, it also blocks the firm's ability to carry forward business losses and depreciation to future years, a cost that's frequently far larger than the immediate late fee itself.

Documents Needed to File ITR-5 for a Firm

• Partnership deed, particularly the clauses governing partner remuneration, interest on capital, and profit-sharing ratio, since these directly determine what Section 40(b) permits.
• Firm's PAN and bank account details.
• Books of accounts and financial statements (profit and loss account, balance sheet), unless the firm is filing under presumptive taxation.
• Tax audit report (Form 3CA/3CB and 3CD), where applicable, along with the acknowledgment number.
• TDS certificates (Form 16A) for any tax deducted on the firm's income, and Form 26AS/AIS to reconcile every entry before filing.
• GST return summaries (GSTR-1 and GSTR-3B), if the firm is GST-registered, since outward supply figures are expected to reconcile with reported gross receipts.

Common Mistakes When Filing ITR for a Partnership Firm

• Assuming the firm gets a basic exemption limit the way an individual does. It doesn't; tax applies from the first rupee of taxable income.
• Paying remuneration or interest beyond Section 40(b) limits without realising the excess isn't deductible for the firm, even though the partner is still taxed on the full amount received.
• Missing the interest deed requirement. If the partnership deed is silent on interest, no interest deduction is available at all, regardless of what's actually paid.
• Overlooking Section 194T TDS on partner payments now that it applies from FY 2025-26, and under-deducting or missing this compliance step entirely.
• Assuming other business expenses remain deductible under presumptive taxation. Under 44AD, only Section 40(b) partner remuneration and interest survive as a separate deduction; everything else is already absorbed into the presumptive percentage.
• Filing ITR-3 instead of ITR-5 for the firm's own return, a mix-up that happens when the firm and an individual partner's filings get confused with each other.

Frequently Asked Questions

Which ITR form should a partnership firm use?

ITR-5. This is the same form LLPs use as well, with a specific field distinguishing which entity type is filing. Individual partners reporting their own remuneration and interest income file ITR-3 separately.

What is the income tax rate for a partnership firm in India?

A flat 30% on the firm's total taxable income, plus surcharge if income exceeds Rs. 1 crore, plus 4% health and education cess. There are no slab rates and no basic exemption limit, unlike individual taxation.

Is a partner's share of profit from the firm taxable?

No. It's fully exempt under Section 10(2A), since the firm already paid tax on that income before distributing it. Only remuneration and interest paid to a partner are separately taxable, in the partner's own hands.

How much can a partnership firm deduct for partner remuneration?

For FY 2025-26, the higher of Rs. 3,00,000 or 90% of the first Rs. 6,00,000 of book profit, plus 60% of book profit beyond that, applies only to working partners authorised for remuneration under a written partnership deed.

Does a partnership firm need a tax audit?

Yes, if business turnover exceeds Rs. 1 crore (Rs. 10 crore where cash transactions stay within 5% of the total), or professional receipts exceed Rs. 50 lakh, or specific presumptive-taxation conditions under Section 44AD aren't met.

What happens if a partnership firm files its ITR-5 late?

Beyond interest and a late fee, a late filing blocks the firm's ability to carry forward business losses and unabsorbed depreciation to future years, which is often the larger practical cost of missing the deadline.

Can a partnership firm opt for presumptive taxation?

Yes, under Section 44AD, the same scheme available to individual businesses. The one firm-specific detail to know: once presumptive income is computed, no further deductions are allowed except partner remuneration and interest within Section 40(b) limits.

Get Your Firm's ITR-5 Filed Correctly

Between Section 40(b) limits, the new Section 194T TDS obligation, and the audit threshold rules, partnership firm taxation has more moving parts than most individual filings, and a partnership deed that doesn't match what's actually reported in ITR-5 is a common, avoidable source of scrutiny. LegalDev's CAs handle ITR-5 filing for partnership firms end to end, including Section 40(b) computation, audit coordination, and TDS compliance.
