What happens if a doctor or other professional with a practice does not file a tax return?

Not filing a return does not stop the tax process. It moves it from you to the Commissioner, adds a penalty, and raises the tax taken from your fees at source until you appear on the Active Taxpayers List (ATL). Each step is set out in the Income Tax Ordinance as amended to 30 June 2026.

What does the law say?

The duty to file, section 114. Section 114(1) requires a return from, among others, every person other than a company whose taxable income exceeds the amount not chargeable to tax, and under clause (b)(ix) any resident person registered with a professional body, including the “Pakistan Medical and Dental Council, Pakistan Bar Council or any Provincial Bar Council, Institute of Chartered Accountants of Pakistan or Institute of Cost and Management Accountants of Pakistan”. Clause (b)(vii) also covers anyone who has obtained a National Tax Number.

The due date, section 118. A return of a person other than a company is due “on or before the 30th day of September next following the end of the tax year to which the return relates”. For tax year 2027, that is 30 September 2027.

Notices, section 114(4) and (5). The Commissioner may by notice require a person who should have filed to do so within thirty days, or another period set in the notice. The notice may cover one or more of the last five completed tax years, or the last ten where the person has not filed for any of the last five.

Penalty, section 182. Serial 1 of the Table applies where a person fails to furnish a return under section 114 within the due date.

ATL, section 100BA. For a person not appearing on the active taxpayers’ list, withholding and the computation of income and tax “shall be determined in accordance with the rules in the Tenth Schedule”. Section 181A lets the Board institute the list and regulate it as prescribed.

How is the late-filing penalty worked out?

Serial 1 charges 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 is Rs. 10,000 for an individual with 75% or more income from salary and Rs. 50,000 in all other cases, which covers a professional in practice. The maximum is 200% of tax payable. The penalty is reduced by 75%, 50% or 25% if the return is filed within one, two or three months after the due date. An Explanation substituted by the Finance Act, 2026 defines tax payable as the higher of the assessed tax or the tax payable for the last year for which a return was duly filed.

Worked example (illustrative figures)

Dr. Faisal, Quetta, 50 days late. His made-up tax payable is Rs. 400,000.

1. Option (a): 0.1% x Rs. 400,000 x 50 = Rs. 20,000.
2. Option (b): Rs. 1,000 x 50 = Rs. 50,000.
3. Higher amount: Rs. 50,000, which equals the Rs. 50,000 minimum.
4. He filed within two months, so the 50% reduction applies. The Table does not say whether the reduction is applied before or after the minimum, so the result could be Rs. 25,000 or Rs. 50,000. This page does not resolve that.

Advocate Sana, Peshawar, 100 days late. Her made-up tax payable is Rs. 2,000,000.

1. Option (a): 0.1% x Rs. 2,000,000 x 100 = Rs. 200,000.
2. Option (b): Rs. 1,000 x 100 = Rs. 100,000.
3. Penalty: Rs. 200,000, below the cap of 200% of Rs. 2,000,000.
4. 100 days is beyond three months, so no reduction applies.

What if I stay off the Active Taxpayers List?

Doubled withholding. Rule 1 of the Tenth Schedule increases the rate of any tax to be deducted or collected from a person not on the ATL by 100% of the rate in the Ordinance, subject to exceptions in rule 10.

Provisional assessment. Under rule 3, where tax was deducted at the higher rate and the return is not filed by the due date, the Commissioner makes a provisional assessment within sixty days, imputing income from the tax deducted and treating it as concealed income. Rule 4 makes it final after forty-five days unless the returns and wealth statements for that year and the preceding year are filed within that time. Rule 5 then allows penalty proceedings under section 182.

Late filers already on the list. Section 100BA(1) also refers to persons on the ATL who did not file by the due date. Rule 1A of the Tenth Schedule, which set rates for them, was omitted by the Finance Act, 2026, so how section 100BA now applies to that group is not clear from the text.

Common mistakes

• Thinking low income means no return. Section 114(1)(b)(ix) covers registered professionals regardless of income.
• Forgetting the wealth statement. Serial 1AA of the section 182 Table has its own penalty of 0.1% of taxable income per week or Rs. 100,000, whichever is higher.
• Expecting the penalty to start small. For a professional, the minimum under serial 1 is Rs. 50,000.
• Assuming old years are safe. Section 114(5) reaches back five years, or ten for persistent non-filers.

What to check in the official text

Read section 114(1), (4) and (5), section 118(3), serials 1 and 1AA of the Table in section 182, section 100BA, section 181A, and rules 1 to 5 and 10 of the Tenth Schedule. The mechanics of inclusion on the ATL are in the Income Tax Rules, and the edition held here is amended only to November 2023.
