What happens if our firm files its return late?

Filing late costs a partnership firm in two separate ways. It loses its place on the active taxpayers’ list (ATL) for that year until it pays a fixed surcharge, and it becomes liable to a penalty that grows with each day of delay. Both apply to the same late return.

What does the law say?

The due date. Section 118(3)(b) requires a person other than a company, which includes a firm, to file its return on or before 30 September following the end of the tax year. The filing duty itself comes from section 114.

The active taxpayers’ list. Section 181A gives the Board power to institute an active taxpayers’ list, regulated as prescribed. Section 182A(1) then says that where a person fails to file a return by the due date in section 118, or by a date extended by the Board or by the Commissioner under section 119, that person shall:

• (a) not be included in the ATL for the year for which the return was not filed within the due date;
• (b) not be allowed, for that tax year, to carry forward any business loss;
• (c) not be issued a refund while it is off the ATL; and
• (d) not be entitled to additional payment for delayed refund, and the period off the list is not counted when that payment is computed.

The way back onto the list. A proviso to clause (a) says that, without prejudice to any other liability, the person shall be included in the ATL on filing the return after the due date if it pays a surcharge of:

Person	Surcharge under section 182A(1)(a)
Company	Rs. 100,000
Association of persons	Rs. 50,000
Individual	Rs. 25,000

The company and AOP figures were raised by the Finance Act, 2026.

The penalty. Entry 1 of the Table in section 182(1) covers any person who fails to furnish a return of income as required under section 114 within the due date. The penalty is the higher of:

• (a) 0.1% of the tax payable for that tax year for each day of default; or
• (b) Rs. 1,000 for each day of default.

The minimum penalty is Rs. 10,000 for an individual with 75% or more of income from salary, and Rs. 50,000 in all other cases, which includes a firm. The maximum is 200% of the tax payable for the tax year. The penalty is reduced by 75%, 50% and 25% if the return is filed within one, two and three months respectively after the due date or extended due date.

An Explanation, substituted by the Finance Act, 2026, defines “tax payable” for this entry as the higher of the tax chargeable on the assessed taxable income, or the tax payable for the immediately preceding tax year for which a return was duly filed.

Worked example (illustrative figures)

Malik Brothers, a hardware trading firm in Multan, files its tax year 2026 return 45 days after the 30 September 2026 due date. Its assessed tax for the year is Rs. 3,000,000, higher than the previous year’s.

1. Daily penalty under clause (a): 0.1% of Rs. 3,000,000 = Rs. 3,000 per day.
2. Daily penalty under clause (b): Rs. 1,000 per day. The higher figure is Rs. 3,000.
3. For 45 days: Rs. 3,000 x 45 = Rs. 135,000.
4. Check against the limits: above the Rs. 50,000 minimum and well below the maximum of 200% of Rs. 3,000,000, which is Rs. 6,000,000.
5. The return was filed more than one month but within two months after the due date, so the penalty is reduced by 50%: Rs. 135,000 x 50% = Rs. 67,500.
6. Separately, to be included in the ATL for tax year 2026, the firm pays the section 182A surcharge of Rs. 50,000.

Total cash cost in this example: Rs. 67,500 + Rs. 50,000 = Rs. 117,500, before any other liability such as default surcharge on late tax.

What if …?

What if the firm made a loss that year? Section 182A(1)(b) says the person is not allowed, for that tax year, to carry forward any loss under Part VIII of Chapter IV. The proviso on the surcharge speaks only of inclusion in the ATL; it does not say that paying the surcharge restores the right to carry the loss forward.

What if the firm had an extension? Section 182A measures lateness against the due date “or by the date as extended” by the Board or by the Commissioner under section 119. A return filed within a granted extension is not late for section 182A.

What if the penalty works out below Rs. 50,000? The proviso sets Rs. 50,000 as the minimum for a firm. The Table does not say in which order the minimum and the 75%, 50% or 25% reduction are applied when a short delay produces a small figure, so that point is not settled on the face of the text.

Common mistakes

• Treating the surcharge as the whole cost. The section 182A surcharge only restores ATL status. The section 182 penalty is separate.
• Using the individual surcharge. A firm pays the AOP rate of Rs. 50,000, not the Rs. 25,000 individual rate.
• Relying on the undertaking. Section 182A(3) applies to an individual, not a firm.
• Assuming a loss year means no penalty. The minimum penalty of Rs. 50,000 applies in all non-salaried cases, and “tax payable” can be measured by the previous year’s tax.

What to check in the official text

Read section 182A in full, including sub-section (3), and entry 1 of the Table in section 182(1) with its provisos and Explanation. The penalty Table does not reproduce well in the site text, so check the figures in the official PDF. Section 181A leaves the detail of the ATL to rules; the Income Tax Rules in this corpus are amended only to November 2023. Relief from penalty in particular cases is dealt with in other sections not covered here.
