A company can be profitable, well run and fully staffed, and still end up with a notice from the Federal Board of Revenue (FBR) because of one missed schedule or one mismatched withholding figure. Company tax returns are less forgiving than individual returns. They involve audited accounts, tax computations, reconciliations and electronic data that must line up with FBR's own records.
This guide walks you through company income tax return filing in Pakistan from start to finish. You will see who must file, which deadline applies, what to prepare, how the IRIS portal flow works, and how to calculate taxable income with a worked example. It also covers late filing, corrections and the mistakes that trigger notices.
How do you file a company income tax return in Pakistan? A company files its return electronically through the FBR's IRIS portal. The steps are:
- Log in with the company's NTN credentials.
- Select the correct tax year and company return form.
- Complete the income, deduction, tax credit and wealth-related schedules.
- Attach financial statements in the required electronic format.
- Submit, then save the acknowledgement.
The form, computation, documents and due date all depend on the company's tax year and the law applicable to that year.
Deadline Update (Verified 22 October 2026)
For Tax Year 2026, FBR extended the filing date to 31 October 2026. The extension covers persons whose original due date was 30 September 2026 and whose date had already been moved to 15 October. ProPakistani's report on the extension describes the notice, and the Income Tax Ordinance extension power sits under Section 214A.
This extension does not automatically apply to every company. A company whose normal due date falls later, such as 31 December following the tax year end, follows its own date unless FBR notifies otherwise. Read the scope of the notice and the FBR due dates page before relying on any date. For a running summary, see our FBR tax return deadline 2026 guide.
Who Must File a Company Income Tax Return in Pakistan?
Every company that exists in the eyes of the law must file a return under Section 114 of the Income Tax Ordinance, 2001. This holds whether the company made a profit, made a loss, or did nothing at all during the year.
Companies That Must File
- Private limited companies
- Public listed and unlisted companies
- Single-member companies (SMCs)
- Branches or permanent establishments of foreign companies
- Companies with income that is fully exempt or taxed under a final regime
If the company is formed under the Companies Act, 2017, treat the return as mandatory. A company registered with SECP is expected to be visible to FBR as a taxpayer too, which means it needs an NTN.
What About Dormant or Nil-Income Companies?
Dormant companies still file. A nil return is a filing that reports no taxable income. A loss return reports a loss, which may be carried forward subject to the law. Skipping either can affect your compliance standing and may attract penalties.
Do Newly Incorporated Companies File Too?
Yes. A company incorporated in the middle of a tax year files for that year, even for a short period with no trade. First-year returns are also the right time to set up clean records. Everything that follows, including losses and depreciation, builds on them.
Understanding the Tax Year
A normal tax year runs from 1 July to 30 June. Tax Year 2026 covers 1 July 2025 to 30 June 2026. A special tax year is a different twelve-month period that FBR has approved for a company, for example one ending in December or September.
This matters because your due date follows your tax year, not the calendar. Many companies miss deadlines by assuming everyone shares one date.
| Item | Normal Tax Year | Special Tax Year |
|---|---|---|
| Period | 1 July – 30 June | Approved period set by FBR |
| Example for TY 2026 | 1 Jul 2025 – 30 Jun 2026 | Depends on approval |
| Due date | Follows the section 118 rule for your category | Follows the date notified for that category |
| Where to confirm | FBR notices and IRIS | FBR notices and IRIS |
For the broader view of how dates have moved this season, see our FBR tax filing deadline 2026 page.
FBR Income Tax Return vs SECP Annual Return
These two filings get confused constantly, and finishing one does not complete the other.
| Feature | FBR Income Tax Return | SECP Annual Return |
|---|---|---|
| Regulator | Federal Board of Revenue | Securities and Exchange Commission of Pakistan |
| Law | Income Tax Ordinance, 2001 | Companies Act, 2017 |
| Purpose | Reports income, deductions and tax payable | Reports company particulars and filings to the registrar |
| Includes tax computation | Includes tax computation | no |
| Includes audited accounts | Yes, in the prescribed electronic format | Filed separately as annual accounts |
A company can be fully compliant with SECP and still be in default with FBR, and the reverse is equally possible. Keep a compliance calendar that tracks both.
Documents to Prepare Before You Log In
Most filing delays come from missing paperwork, not from the portal. Collect everything first. Our tax season checklist can help you build a calendar.
Core Financial Records
- Audited financial statements, including the statement of profit or loss, statement of financial position, cash flow statement and notes
- Trial balance and general ledger extracts
- Fixed asset register with additions, disposals and depreciation
Tax-Specific Records
- Tax computation sheet showing accounting profit to taxable profit
- Tax depreciation schedule
- Withholding tax certificates and the withholding statement data on IRIS
- Advance tax payment records and challans (CPRs)
- Opening and closing tax loss balances
- Brought-forward minimum tax credits, if any
Identity and Registration Data
- NTN and IRIS login credentials
- Company registration details and authorized signatories
- Bank account details and the latest SECP particulars
A useful practical tip is to combine scanned certificates into a single organized file before the filing session begins. Our guide on combining tax documents into one PDF shows how.
A new rule matters here. According to a summary of the Finance Act 2026 at Regfollower, companies must file the financial statements accompanying their returns exclusively in an electronically readable file format from Tax Year 2026 onwards. Confirm the exact format requirement on IRIS before upload. Do not wait until the final day to discover that your PDF-only accounts are not accepted.
Step-by-Step: How to File a Company Income Tax Return on FBR IRIS
The portal screens change over time, and FBR has been rolling out a refreshed system. Treat this as the process map, then confirm each screen live. For more portal background, read our FBR IRIS portal overview and the IRIS 2.0 tax filing guide.
Step 1: Confirm Your NTN and IRIS Access
Your company needs an active NTN registered under its legal name. If you are unsure how registration works, start with our explainer on what an NTN is. Make sure the registered email and mobile number are current, because verification codes go there.
Step 2: Log In to the Company Account
Visit iris.fbr.gov.pk and sign in with the company's credentials. A common problem is that the person logging in is the director, not the registered user. Make sure the account belongs to the company and not to an individual profile. Our IRIS income tax return guide lists typical login problems.
Step 3: Open the Correct Tax Year Return
Go to the declaration or return menu and select the Income Tax Return for companies for Tax Year 2026 (or the tax year you are filing). Choosing the wrong form is a costly mistake because the schedules differ. Check that the form version matches the one FBR notified for that year.
Step 4: Complete the Return Schedules
You will typically work through:
- Income section for revenue, other income and exempt or final-tax income
- Deductions for admissible business expenses
- Depreciation and amortization using tax rates
- Losses and credits brought forward
- Tax chargeable and any minimum tax comparison
- Withholding and advance tax for adjustment
Fill the sections in this order, because later sections pull data from earlier ones.
Step 5: Upload the Financial Statements
Attach the audited accounts in the electronic format the portal requires, and make sure the figures match your computation. The IRIS system and FBR officers compare accounts with the return. A gap between the two is among the most common triggers for an audit selection.
Step 6: Reconcile Withholding Tax
Compare your withholding tax certificates with the figures FBR shows in the withholding statements on your profile. If your records show more than FBR does, investigate before claiming the full amount. Our withholding tax Pakistan guide explains how deductions arise and how they are credited.
Step 7: Calculate and Pay Any Balance
If the tax payable exceeds what has already been deducted or paid, pay the shortfall through a challan before final submission, then attach or reference the payment as the form requires. The payment can be done through any authorized bank channel or e-payment service. Always keep the CPR.
Step 8: Review the Declaration and Submit
Read the draft summary carefully. Check the tax year, NTN, income figures, tax paid and refund or payable position. Then verify and submit electronically.
Step 9: Download the Acknowledgement
After submission, download the acknowledgement or receipt. Save it with the return copy, your computation and the challans. This is your proof that the return was filed.
Step 10: Check the Return Status
Return to IRIS and confirm that the return appears as filed. This final check matters, since this filing season has been marked by slowdowns and glitches. In recent coverage, Daily Pakistan noted tax professionals reporting delays and technical problems with the system. Do not assume a successful click means a successful filing.
How to Calculate Taxable Income for a Company
Your return is only as good as your computation. Taxable income is not the profit you see in your accounts. It is accounting profit adjusted by tax law.
Accounting Profit vs Taxable Profit
Accounting profit follows the Companies Act and accounting standards. Taxable profit follows the Income Tax Ordinance. The two differ because tax law accepts some expenses, rejects others and uses its own depreciation rates.
The usual adjustments are:
- Add back inadmissible expenses, such as fines and penalties, personal expenses of directors, and expenses lacking proper documentation or withholding compliance
- Add back accounting depreciation because tax uses its own
- Deduct tax depreciation at the rates in the Third Schedule
- Adjust for exempt income or income under the final tax regime, which is taxed separately
- Deduct brought-forward losses, subject to time limits in the law
Worked Example (Illustrative Only)
Imagine a private limited company, Alpha Trading (Pvt) Ltd, with a normal tax year and turnover of Rs 200 million. The figures below are fictional and use the 29% rate for illustration.
Now run the minimum tax check. If minimum tax at the applicable rate on turnover exceeds your normal tax, the higher amount applies. Many sectors use 1.25% of turnover, but some use different rates, so verify under Section 113. On Rs 200 million turnover, 1.25% gives Rs 2.5 million, which is lower than Rs 3.045 million, so normal tax applies.
If you want a quick sanity check before engaging an accountant, try our business income tax calculator or the FBR tax calculator Pakistan. They do not replace professional computation, but they help you spot a result that looks off. Our post on calculating your tax before meeting an accountant shows how to prepare.
Corporate Tax Rates, Minimum Tax and Super Tax
Rates are set by the Finance Act each year, so always verify the figures for the tax year you are filing.
- Banking companies are generally taxed at a higher rate, commonly cited as 39%.
- Most other companies are generally taxed at 29%.
- Small companies may be eligible for a lower rate, commonly cited as 20%, if they meet the definition.
- Minimum tax under Section 113 applies when it exceeds normal tax.
- Super tax under Section 4C applies to high-earning persons.
Pay attention to the tax year split. The Finance Act 2026, enacted on 26 June 2026, changed super tax from Tax Year 2027 onward. ARY News reported that super tax is being abolished for general taxpayers with income up to Rs 500 million, while a 10% rate stays for banking companies and certain other categories. Exporters with more than 80% of receipts from exports may qualify for full exemption. These changes apply to Tax Year 2027, so a Tax Year 2026 return generally follows the earlier rules. Our super tax Pakistan guide explains who pays.
Withholding Tax and Advance Tax: How to Adjust Them
Most of a company's tax is paid before the return is filed, through two channels.
Withholding Tax (Tax Deducted by Others)
When customers, banks or government bodies pay your company, they often deduct tax at source. That deduction is evidence of tax paid on your behalf. Depending on the nature of the receipt, it is either:
- Adjustable, meaning it is credited against your final tax liability, or
- Final, meaning the income is fully taxed at that deduction and not taxed again
Always identify which regime each receipt falls under. Mixing them up overstates or understates your income.
Advance Tax (Tax You Pay in Instalments)
Companies generally pay advance tax during the year under Section 147, typically in quarterly instalments based on an estimate. These payments are credited against your final tax. Underpayment can attract default surcharge. Learn more in our guide on how advance tax is calculated in Pakistan.
A Practical Reconciliation Routine
- Download the withholding statements from your IRIS profile
- Match each deduction to a certificate or bank advice
- Flag differences above a small threshold
- Ask the withholding agent to correct any statement they filed wrongly
- Claim only what is supported by both records
Use our Pakistan withholding tax calculator to check expected deductions on common transactions.
After You Submit: What Happens Next
Submitting the return is not the end of your obligations.
Return Submission Does Not Mean Tax Paid
A filed return shows what you declared. Tax is only settled when the full amount due has been paid. Filing without payment leaves the balance outstanding, and recovery proceedings can follow.
Check Your Active Taxpayer List Status
Filing generally affects your presence on the Active Taxpayer List (ATL), which in turn affects the rates of withholding applied to your transactions. Read our FBR Active Taxpayer List guide and the comparison of filer vs non-filer in Pakistan for how this works in practice.
Keep Your Records
Retain computations, schedules, certificates and challans. FBR can select returns for audit, and the Income Tax Ordinance allows amendment of assessment under Section 122 within the time limits it sets. Our article on FBR AI tax checks in 2026 explains how risk-based selection is evolving.
What If You File Late or Make a Mistake?
Late Filing
Missing the due date can bring penalties under Section 182 and can affect ATL status. The exact amounts and conditions are set by the law in force, so check current provisions rather than relying on a figure from an old blog. Our late filing penalty guide tracks the main consequences.
A late return is still better than none. File as soon as possible, pay what you owe, and keep proof.
Revising a Submitted Return
If you notice an error after submission, you can generally file a revised return within the window and conditions the law allows. After that window, you may need to apply to the Commissioner or seek an amended assessment. The rules on timing and approval have changed over the years, so confirm them with a tax professional before acting.
Responding to a Notice
If FBR issues a notice under Section 120 or another provision, respond within the stated time. Provide the documents requested and keep your reply factual and organized. Our guide on how to respond to an FBR tax notice walks through a sensible approach.
Common Company Tax Return Mistakes
From experience with how these filings go wrong, the same errors recur:
- Wrong tax year or form, which forces a revision or rejection
- Financial statements that do not match the return
- Claiming withholding tax that is not reflected on IRIS
- Missing inadmissible expenses in the computation
- Using accounting depreciation instead of tax depreciation
- Forgetting the minimum tax comparison
- Ignoring brought-forward losses or credits
- Filing at the last minute when the portal is congested
- Assuming SECP compliance covers FBR compliance
Most of these are preventable with a simple internal review a week before the due date.

What is the company income tax return deadline for Tax Year 2026?
FBR extended the Tax Year 2026 deadline to 31 October 2026 for persons whose original date was 30 September 2026. Companies with a different normal due date should confirm theirs on the FBR due dates page, since the extension has a defined scope.
What documents are needed for corporate tax filing?
You need audited financial statements in electronic format, a tax computation, a tax depreciation schedule, withholding tax certificates, advance tax records, loss records and NTN credentials.
Does a company need to file a return if it has no profit?
Yes. A company with no profit, no income or a loss still files a nil or loss return, and the loss may be carried forward subject to the law.
Can a company file its tax return online?
Yes. Online filing through IRIS is the standard method, and the return is submitted electronically with accompanying accounts.
Does submitting a return mean the company has paid all its tax?
No. Filing declares your income and tax position. Any balance payable must be paid separately through a challan.
What happens if a company files late?
Late filing can attract penalties under Section 182 and may affect ATL status and withholding rates. File as soon as possible and verify current penalty provisions.
Can I revise a company return after submission?
Often yes, within the window and conditions the law sets. Beyond that window, correction may need Commissioner approval or an amended assessment.
Is an FBR income tax return the same as an SECP annual return?
No. The FBR return reports income and tax under the Income Tax Ordinance. The SECP annual return reports company particulars under the Companies Act, 2017. Each needs to be filed separately.
Conclusion:
Company income tax return filing in Pakistan comes down to five habits: pick the correct tax year, prepare documents early, reconcile accounts to tax, match withholding with IRIS, and keep proof of everything. Do these well and the portal becomes the easy part.
