Which professional firms pay a 40% top rate instead of 45%?

A professional firm organised as an association of persons (AOP) pays 40% instead of 45% on the top band of the tax table, but only if a law or its professional regulator’s rules stop it from becoming a company. The concession sits in a proviso to clause (1) of Division I of Part I of the First Schedule to the Income Tax Ordinance, 2001, and it touches only the rate on taxable income above Rs. 5,600,000.

What does the law say?

Clause (1) of Division I sets the slab table for every individual and association of persons except a salaried individual. Its last row, serial 6, charges Rs. 1,610,000 plus 45% of the amount exceeding Rs. 5,600,000.

The proviso that follows the table reads, in the official text: “Provided that in the case of an association of persons that is a professional firm prohibited from incorporating by any law or the rules of the body regulating their profession, the 45% rate of tax mentioned against serial number 6 of the Table shall be 40%.”

Three conditions come out of those words:

1. The taxpayer is an association of persons. Section 80(2)(a) says this includes a firm, and section 80(2)(c) defines a firm as the relation between persons who have agreed to share the profits of a business carried on by all or any of them acting for all.
2. The AOP is a professional firm.
3. It is prohibited from incorporating by a law or by the rules of the body that regulates the profession.

Section 92(1) still applies to such a firm: it is taxed separately from its partners, and a partner’s share out of income on which the firm has paid tax is exempt.

What does the law leave undefined?

• “Professional firm” is not defined in the proviso, and the Ordinance does not list the professions it has in mind.
• Which laws or rules count is not stated. The proviso does not name any statute or regulator. Whether a particular profession’s rules bar incorporation is a question of those rules, which are outside this corpus.
• Mixed firms. The proviso does not say how it applies to a firm whose partners belong to different professions, or that carries on professional and non-professional work.

The same wording, “a professional firm prohibited from incorporating by any law or the rules of the body regulating the profession”, appeared in the old section 92(2), which the Finance Act, 2007 omitted. The old version made such firms pass-through entities. The current proviso does not do that; it only lowers one rate.

Worked example (illustrative figures)

A mid-sized firm. A Lahore firm of advocates, assumed to be barred from incorporating by its regulator’s rules, has made-up taxable income of Rs. 8,000,000 for tax year 2027.

1. Amount above Rs. 5,600,000: Rs. 2,400,000.
2. At 45%: Rs. 1,610,000 + Rs. 1,080,000 = Rs. 2,690,000.
3. At 40% under the proviso: 40% of Rs. 2,400,000 = Rs. 960,000. Tax: Rs. 1,610,000 + Rs. 960,000 = Rs. 2,570,000.
4. Difference: Rs. 120,000, which is 5% of Rs. 2,400,000.
5. Taxable income does not exceed Rs. 10 million, so no surcharge.

A larger firm. The same firm with made-up taxable income of Rs. 20,000,000.

1. Amount above Rs. 5,600,000: Rs. 14,400,000.
2. At 40%: Rs. 5,760,000. Division I tax: Rs. 1,610,000 + Rs. 5,760,000 = Rs. 7,370,000.
3. Surcharge under section 4AB, since taxable income exceeds Rs. 10 million: 10% of Rs. 7,370,000 = Rs. 737,000.
4. Total: Rs. 8,107,000, before credits and any super tax.
5. At 45% the Division I tax would be Rs. 1,610,000 + Rs. 6,480,000 = Rs. 8,090,000, surcharge Rs. 809,000, total Rs. 8,899,000. The proviso saves Rs. 792,000.

What if …?

What if the firm’s income is Rs. 5,600,000 or less? Serial 6 never applies, so the proviso makes no difference. The lower rows of the table are the same for every AOP.

What if the profession allows incorporation but the partners chose a partnership? The proviso depends on being “prohibited from incorporating”. A firm that could incorporate but has not does not meet that wording and stays at 45%.

What if a partner is a company? The first proviso to section 92(1) excludes the company’s share from the AOP’s total income and taxes the company at the company rate. The 40% proviso then applies to the AOP’s remaining income, if the AOP otherwise qualifies.

Common mistakes

• Applying 40% across the board. Only the 45% at serial 6 becomes 40%.
• Reducing the Rs. 1,610,000 fixed amount. The proviso changes the rate, not the fixed amount.
• Claiming it as a sole practitioner. The proviso is limited to an association of persons.
• Forgetting the surcharge. Section 4AB applies to AOPs whose taxable income exceeds Rs. 10 million, including professional firms.

What to check in the official text

Read clause (1) of Division I of Part I of the First Schedule and the proviso after its table in the official PDF; the proviso runs across a page break there. Read section 92(1) and section 80(2). For whether a particular profession is barred from incorporating, check the law or rules of that profession’s regulator, which this site does not hold.
