Firm Taxation explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Firm taxation treats a partnership as a separate assessee taxed at 30%, with a 12% surcharge above Rs 1 crore, marginal relief and a 4% cess. Interest on capital is deductible up to 12%. Two passages in the handbook's tax chapter need correcting before use.
Firm taxation starts with the firm as a separate assessee
Under section 2(7) of the Income-tax Act, 1961 an assessee is a person liable to pay tax or any sum payable, or who has an obligation to pay tax. A partnership is an assessee, and so the income earned by the firm during a financial year is subject to taxation in its hands. The firm computes its taxable income after permissible deductions and allowances and pays tax at the applicable rates. That, as the handbook puts it, "ensures that the partnership firm is treated as a separate entity for tax purposes, distinct from its partners".
That sentence is the correct statement of Indian firm taxation, and it should be preferred over the "pass-through" description that appears in the handbook's Chapter 1 list of advantages.
The firm taxation rate structure
| Element | Position |
|---|---|
| Rate | 30% on taxable income |
| Surcharge | 12% where taxable income exceeds Rs 1 crore |
| Health and Education Cess | 4% on the total tax amount, including surcharge |
| Marginal relief | Where net income exceeds Rs 1 crore, tax plus surcharge shall not exceed the tax on Rs 1 crore by more than the amount of income exceeding Rs 1 crore |
| Interest on capital | Deduction of up to 12% on interest paid on capital |
| Return | Mandatory annually, regardless of income or loss; a NIL return is still required |
The "deductions allowed" list — read it as disallowances
Under the heading "Deductions Allowed", the handbook says that when computing the liability of income tax on a partnership firm, deductions are permitted for:
- "Remunerations or interest paid to partners that do not conform to the terms of the partnership agreement."
- "Salaries, bonuses, remunerations, and commissions are paid to non-working partners of the firm."
- "If remuneration paid to partners complies with the partnership deed but relates to transactions that pre-date the partnership deed."
Every one of those three is a disallowance, not a deduction. Section 40(b) denies a deduction for payments that do not conform to the deed, for remuneration to a non-working partner, and for remuneration relating to a period before the date of the deed. The list appears to have been drawn from a "what is not allowed" source and re-headed.
Reading the heading literally would lead an adviser to claim exactly the three things that get disallowed on assessment. Read section 40(b) itself, and treat these three as the tests a payment must pass: it must conform to the deed, go to a working partner, and relate to a period on or after the deed's date.
The handbook gets the underlying law right elsewhere — its Annexure introduction correctly explains CBDT Circular No. 739 dated 25 March 1996 and the need for a properly drafted remuneration clause. The defect is in this list alone.
The minimum alternate tax paragraph
The handbook states: "Similar to income tax applicable for a company, partnership firms are subject to minimum alternate Tax. A minimum alternate tax of 18.5% of adjusted total income is applicable."
Minimum Alternate Tax is the company provision in Chapter XII-B. A firm is instead within the Alternate Minimum Tax regime in Chapter XII-BA, which is not simply the same tax under another name — AMT applies only where the assessee claims the specified deductions the chapter identifies, so an ordinary trading firm claiming none of them is outside it altogether.
Presenting AMT as an across-the-board 18.5% floor on all firm taxation is therefore wrong in both name and reach. Read Chapter XII-BA and check the current rate and applicability before advising that any floor applies.
Returns, forms and deadlines in firm taxation
The handbook states that firms file through ITR-4 or ITR-5: ITR-4 for firms with total income up to Rs 50 lakh and business or professional income computed on a presumptive basis; ITR-5 for firms required to get their accounts audited.
That description of ITR-5 is narrower than the form's actual scope — ITR-5 is the return for firms, LLPs, AOPs and BOIs generally, not only for audited firms. Check the applicable form from the current instructions rather than from this summary.
The deadlines are given as 31 July where the firm is not subject to audit, and 31 October where an audit is necessary.
Books and tax audit under firm taxation
Books of account must be maintained if the firm's sales, turnover or gross receipts exceed Rs 25,00,000, or if income from business exceeds Rs 2,50,000, in any of the three preceding years. The handbook states this twice, once with a typographical "lahks" for lakhs.
A tax audit is required if sales, turnover or gross receipts exceed Rs 1 crore in the financial year — and the handbook adds, without elaborating, that the firm "may be required to get its account audited in certain other circumstances".
That last sentence is carrying a great deal of weight. The audit provision has both an increased threshold where cash receipts and payments are within prescribed limits, and separate triggers connected with the presumptive taxation provisions. Neither is set out. Read the audit section itself for any firm near the limit.
GST compliance alongside firm taxation
Registration is required in three situations:
- Threshold. Where aggregate turnover exceeds Rs 40 lakh for the supply of goods or Rs 20 lakh for the supply of services. Once crossed, the application must be submitted within 30 days.
- Nature of business. Mandatory irrespective of turnover for exports, interstate supply of goods, e-commerce suppliers or operators, casual taxable persons, non-resident suppliers, input service distributors, persons liable under reverse charge, and those supplying goods using the brand name of others.
- Industry practice. Even where not mandated — because business customers prefer purchasing from GST-registered dealers to avail input tax credit, and because an inverted rate structure can reduce profitability without registration.
Having given Rs 40 lakh for goods and Rs 20 lakh for services, the handbook says two pages later, under Filing of GST Returns, that "every partnership firm is required to be under GST if its aggregate annual turnover exceeds Rs. 20 lacs".
The two cannot both be right for a firm supplying goods. Work from the first statement, which distinguishes goods from services, and check the position for the State — special category States have their own lower thresholds, which the handbook does not mention at all.
Five practical points the handbook adds on firm taxation and GST are worth keeping:
- The firm's registration is approved only if the GST registrations of the individual partners are regular; where a partner's number was cancelled for non-filing, the firm's registration follows only after all pending returns including GSTR-10 are filed.
- The address in the partnership deed must match the address given for GST registration; on a change of address an amended deed must be submitted.
- If the firm defaults, all partners during the period of default are jointly and severally liable.
- On a change in partners, the registration profile must be updated by a GST amendment application.
- The name on the PAN and Aadhaar of the partners must match for E-KYC, which avoids physical verification of the premises.
Registered firms usually file GSTR-1, GSTR-3B and GSTR-9, or GSTR-4 under the composition scheme, which can be opted for at registration or at the start of the next financial year.
Other filings that sit outside firm taxation
- TDS return — where the firm has a valid TAN; the form depends on the purpose of deduction.
- EPF — registration is required if the firm employs more than ten persons, and filing of the EPF return then becomes mandatory.
Practical checklist on firm taxation
- Describe the firm as a separate assessee, never as a pass-through.
- Test every partner payment against the three section 40(b) conditions — deed, working partner, period.
- Read Chapter XII-BA before asserting any alternate minimum tax floor.
- Cap interest on capital at 12% and say so in the deed.
- File a NIL return in a dormant year.
- Check the current audit thresholds, not the bare Rs 1 crore figure.
- Keep the deed address and the GST address aligned, and amend both together.
- Update the GST profile on every change in partners.
Common mistakes
- Claiming the three "deductions allowed" from the handbook's list.
- Paying remuneration to a non-working partner and expecting a deduction.
- Backdating remuneration to a period before the deed.
- Applying an 18.5% MAT floor to an ordinary firm.
- Using the Rs 20 lakh threshold for a firm supplying goods.
- Changing the business address without amending the deed.
