How to Revise a Filed Income Tax Return on IRIS (2026)

You filed your return, saw the "Completed Task" status, and relaxed. Then you found a missed bonus, a wrong withholding figure, or a bank account left out of your wealth statement. That sinking feeling is common, and it is fixable.

Pakistan's tax law lets you correct a filed return. You do it through the FBR's online portal, IRIS, under Section 114(6) of the Income Tax Ordinance, 2001. The process is simple once you know the rules, but a wrong move can trigger delays, notices, or avoidable penalties.

This guide explains who can revise, when approval is needed, how to apply, what to write as your reasons, and what to do when IRIS does not cooperate.

Can You Revise a Filed Income Tax Return on IRIS?

Yes. A taxpayer who discovers an omission or wrong statement in a filed return can apply to revise it through IRIS under Section 114(6). The FBR's official filing guidance says a return can be revised within five years of the original filing. You first file an application for revision in IRIS. Once it is approved, you submit the revised return.

Three points to remember:

• A revised return corrects your original return. It is not a second original return.
• Whether you need the Commissioner's approval depends on your circumstances. This is explained below.
• A wealth statement follows a different route from a return of income.

What Is a Revised Income Tax Return?

A revised return is an updated version of a return you already filed. It replaces the figures in the original with corrected ones. Think of it as editing a submitted form, not starting a fresh one.

People revise returns for many reasons:

• Income was left out, such as rental income, a bonus, or freelance receipts.
• A withholding tax credit was missed or entered wrongly.
• A deduction, allowance, or tax credit was claimed incorrectly.
• The tax payable was miscalculated.
• The IRIS system did not allow a legitimate credit when you first filed.

That last case is real. In a widely reported matter, the Federal Tax Ombudsman directed the FBR to fix IRIS glitches. They had stopped a taxpayer from claiming a pension fund credit under Section 63, even after the Commissioner approved the revision. You can read the Business Recorder report on the FTO order for background.

If you are still learning the basics of the portal, start with our guide on what the FBR IRIS portal is and how tax filing works in Pakistan.

Section 114(6) Explained in Plain English

Section 114(6) is the legal basis for revising a return. It allows a person who has filed a return and later finds an omission or wrong statement to file a revised return, subject to conditions.

The conditions you may meet include:

1. Written reasons explaining why you are revising.
2. Revised accounts or revised audited accounts, where your return relies on accounts.
3. Commissioner Inland Revenue approval in certain situations.
4. Compliance with the applicable time limit.

Here is where you must be careful. Several third-party tax blogs describe a "60-day window" in which approval is not needed. Others describe approval as the standard route. The exact rule depends on the version of the law in force, the nature of your revision, and the sub-clause that applies. Some explainers cite sub-clauses such as 114(6)(ba), which was reportedly used in the FTO case above.

My practical advice: do not rely on a blog's summary of the timing rule, including this one. Read the current text of the Income Tax Ordinance, 2001 on the FBR website and confirm which condition applies to you before you file.

How Section 114(6A) Fits In

Section 114(6A) is usually discussed alongside 114(6) in connection with additional tax and notices. In general terms, a voluntary revision made before the tax authorities start proceedings is viewed far more favourably than a correction made after a notice arrives. Check the exact wording of the section for the penalty consequences that may apply to your case.

Revised Return vs Amended Assessment: Don't Confuse Them

These two terms sound alike but work very differently.

If you receive a notice under Section 122, your options change. At that stage, speak with a qualified tax advisor before filing anything. Our guide on how to respond to an FBR tax notice in 2026 walks through the first steps.

Revising a Return vs Revising a Wealth Statement

This is one of the most misunderstood points. The two filings are related but separate.

• Return of income: You apply for revision in IRIS and, where required, wait for approval before filing the revised return.
• Wealth statement: The FBR's guidance says a wealth statement can be revised in IRIS before you receive a notice under Section 122(9). It adds that you do not need to apply for approval to do so.

The wealth statement revision relies on Section 116(3). If your income changes, your assets and liabilities usually need to reconcile as well, so revising one often means revisiting the other.

Many taxpayers get this wrong. They fix the income figure but forget that the bank balance, property, or loan entry no longer matches. Always run a reconciliation after any change. Our detailed walkthrough on how to fill a wealth statement and the overview of wealth statement requirements in Pakistan will help here.

Who Should Revise Their Return?

You should consider revising if any of the following apply:

• Salaried individuals who missed a bonus, gratuity, or a tax deducted at source. See our guide on bonus and gratuity tax in Pakistan.
• Freelancers who under-reported foreign remittances or forgot an expense. Read more in our freelancer income tax guide.
• Landlords who entered rental receipts incorrectly. Our page on rental income tax in Pakistan explains the rules.
• Business owners whose accounts changed after filing.
• Investors who forgot capital gains. See capital gains tax on property and stocks.
• Anyone whose withholding credits did not match the FBR's records.

You do not need to revise for every tiny typo that has no effect on tax. Judge it by materiality. If the number changes your income, credits, deductions, tax payable, or wealth reconciliation, fix it.

Before You Start: What to Prepare

Preparation saves time and prevents rejection. Gather these items before you open IRIS:

• Your NTN and IRIS login credentials. If you need background, read what an NTN is.
• A copy of the original filed return and its acknowledgment.
• Supporting documents for the correction: salary slips, bank statements, withholding certificates, rent agreements, invoices, or accounts.
• The correct tax year you want to revise.
• A clear explanation of what was wrong and what the correct figure is.
• A recalculation of your tax. Use the Pakistan income tax calculator or the FBR tax calculator to compare the original and corrected figures.
• Your wealth statement figures, if the revision affects them.

A good habit: keep a one-page reconciliation showing the original number, the corrected number, the difference, and the document that proves it. If the department ever asks questions, this page saves you hours.

Step-by-Step: How to Revise a Filed Return on IRIS

Important note: IRIS menus and labels change over time. The steps below reflect the general workflow described in FBR guidance and by other practitioners. Verify each label on the live portal before you click, because the FBR's published FAQ may describe an older interface.

Step 1: Log In to IRIS

Go to the official FBR IRIS portal and sign in with your credentials. Always use the official address and never enter your details on look-alike pages.

Step 2: Open the Declaration Menu

Go to the Declaration menu and look for the option related to revision or the application for revision of the return of income. In some interface versions, you will find it under the same area as the original return form.

Step 3: Select the Correct Tax Year

Choose the tax year of the return you want to revise. This sounds trivial, but choosing the wrong year is one of the most common errors. Double-check the year against your original acknowledgment.

Step 4: Complete the Application for Revision

Enter your reasons for revision in the field provided. Keep them factual, specific, and honest. The next section shows how to do this well.

Attach or keep ready any supporting documents. Then submit the application.

Step 5: Check the Application Status

After submission, check the status in your IRIS workspace. Look in the task folders for the application and its outcome. Do not assume anything is approved until the status says so.

Step 6: File the Revised Return After Approval

Once the application is approved, the revised return becomes available for the tax year. Open it, correct the relevant income, deduction, credit, and tax figures, and update the wealth statement if needed.

Step 7: Submit and Save Proof

Submit the revised return and save the acknowledgment. Make sure the submission moves out of the Draft folder to Completed Task. A return sitting in Draft is not filed.

Step 8: Pay Any Additional Tax

If the revised return shows more tax payable, pay it promptly using the payment channel generated through IRIS. Keep the payment receipt with your records.

How to Write Strong Reasons for Revision

The reasons field is where many applications fail. Vague text invites questions. Good reasons are short, factual, and tied to evidence.

What to include:

• What was wrong in the original return
• Why the error happened
• What the correct figure is
• What document supports the correction

Example 1: Missed income

"While preparing my records, I found that a performance bonus of Rs. 250,000 received in March was not included in my salary income. I am revising the return to declare the correct total income. The salary certificate is available for verification."

Example 2: Wrong withholding credit

"The original return recorded withholding tax on bank profit incorrectly. The correct tax deducted, as shown in my bank's certificate, is higher. I am revising to claim the correct adjustable tax."

Example 3: A credit that IRIS blocked

"The system did not allow me to claim a tax credit I am entitled to at the time of filing. I request approval to revise the return so the admissible credit is correctly reflected."

What to avoid:

• "Mistake" with no detail
• Blaming the system without explanation
• Reasons that contradict your documents
• Long, emotional narratives

Honesty matters here. If a correction increases your income, say so plainly. A truthful, early correction is almost always better than being caught later.

What If the Revision Increases or Decreases Your Tax?

The effect on your tax payable often shapes how smooth the process is.

If Tax Payable Increases

You will owe more tax. Pay the difference promptly. Delay can attract a default surcharge under the Ordinance, so confirm the exact rate and start date in the current law. Where income was under-declared, the department's view of a voluntary correction matters, which is why Section 114(6A) deserves a careful read.

If Tax Payable Decreases or a Refund Increases

Expect closer scrutiny. A revision that reduces your liability or raises a refund claim is more likely to need approval and supporting evidence. Keep documents ready, and expect the Commissioner's office to review the reasons.

If Nothing Changes in Tax

Sometimes a revision only corrects classification or wealth reconciliation. These are usually the simplest, but you should still explain the reason clearly.

Common Reasons IRIS Revision Requests Get Delayed or Rejected

Most problems are avoidable. Watch for these:

1. Wrong tax year selected. Always verify before submitting.
2. Weak or generic reasons. "Correction needed" is not an explanation.
3. Missing documents. The reviewer cannot verify your claim.
4. Mismatch with FBR records. Your withholding figures do not match third-party data.
5. Unreconciled wealth statement. Income changed, but assets did not.
6. Filing the revised return before approval. Where approval is required, wait for it.
7. Revising after a notice. Your options may be restricted, so take advice first.
8. Ignoring accounts. Business taxpayers may need revised accounts.

If an application is rejected, read the order carefully. It usually states the reason. You can respond with clearer reasons and better documents, or explore other remedies with a professional.

Troubleshooting: What If the Revision Option Does Not Appear?

This happens often enough to deserve its own section.

Check these first:

• You are logged into the correct profile.
• You selected the right tax year.
• The original return shows in Completed Task, not Draft.
• Your application has actually been approved, if approval is needed.
• You are not past the applicable time limit.
• Your browser is updated and cache is cleared. Try another browser.

If it still does not work:

• Take screenshots showing the error and the date.
• Contact the relevant Regional Tax Office or Large Taxpayer Office and request written support.
• Escalate through the FBR helpdesk channels.
• In genuine system-failure cases, consider a complaint with the Federal Tax Ombudsman. The FTO case reported by TechJuice shows this route has worked when a Commissioner-approved revision could not be processed.

Document everything. A timeline of dates, emails, and screenshots strengthens any later complaint.

Can You Revise After Receiving an FBR Notice?

This is a high-risk situation. If you receive a notice, such as one for amendment of assessment or an audit, the rules for what you can still do may change. Filing a revision at that point without understanding the consequences can backfire.

For notices, do this:

1. Read the notice fully and note the deadline.
2. Do not ignore it.
3. Gather your documents.
4. Speak with a qualified tax consultant before filing a revision.

Our article on what to do when you receive an FBR tax notice will help you prepare your response.

How Long Does the Process Take?

There is no single reliable answer. Some practitioner blogs mention approval within about 36 business hours, but real timelines vary with the Commissioner's office, the complexity of your case, and the documents provided. Plan for days or weeks rather than hours, and file well before any personal deadline. Keep checking your IRIS status instead of waiting for an email.

Practical Tips From Real-World Filing Experience

These habits reduce stress and rejection:

• Revise early. The sooner you correct, the better it looks and the smaller the consequences.
• Fix the cause, not just the number. If a withholding certificate was missing, collect all of them.
• Reconcile before you submit. Income, tax, assets, and liabilities must tell the same story.
• Keep a revision file. Store the original return, application, approval, revised return, and payment proof together. Our tax season checklist for Pakistan suggests a simple record-keeping routine.
• Use calculators for a sanity check. Compare the old and new tax. If the gap seems odd, investigate before filing.
• Know your slab. Check the latest income tax slabs for FY 2026-27 to confirm that the rate you applied is right.
• Mind the filer status. Corrections that affect your status can change withholding rates. See filer vs non-filer differences in Pakistan.
• Avoid common calculation mistakes. Our guide on income tax calculator mistakes lists errors that frequently lead to revisions.

A Worked Example

Imagine a salaried employee, Ayesha, who filed her return and later found that her employer had paid a Rs. 300,000 bonus that never appeared in her salary income.

Here is how she might handle it:

1. She checks her salary certificate to confirm the amount.
2. She recalculates her tax with the correct income.
3. She applies for revision in IRIS, selecting the correct tax year and writing a short, factual reason.
4. After approval, she files the revised return with the bonus included and the matching tax deducted credited.
5. She updates her wealth statement so that the extra income is reflected in her savings.
6. She pays any extra tax and saves the acknowledgment.

Nothing here is complicated. Each step simply follows the evidence.

What Happens After You Submit the Revised Return?

After submission, keep checking the following:

• The revised return appears under Completed Task.
• The acknowledgment is generated.
• Any payment has been recorded.
• No new notice arrives.

A submitted revised return is not a guarantee against future review. The department can still examine your records, so keep documents for the period required by law. Do not treat a revised return as automatically accepted just because it was submitted. Check its status, and confirm the legal conditions were met.

Is There a Penalty for Revising a Return?

Revising is not a penalty in itself. The law offers the route precisely so that taxpayers can correct honest errors. Consequences arise from what the revision shows:

• Additional tax unpaid on time may attract a default surcharge.
• Under-reporting discovered by the department first can lead to harsher treatment than a voluntary correction.
• False statements can create serious legal exposure.

Because penalty provisions have specific wording and amounts that the Finance Act can change, check the latest text of the Ordinance and any Finance Act changes before you act. Late filing is a separate issue, and our guide on income tax return late filing penalty explains it.
