How to File Your FBR Annual Income Tax Return as a Business: Step-by-Step Guide (2025)

Every business registered in Pakistan — whether a sole trader, partnership, private limited company, or SME — is required to file an annual income tax return with the Federal Board of Revenue (FBR). The deadline for businesses is September 30 each year, covering the fiscal year from July 1 to June 30.

Despite this, a large number of Pakistani SMEs either miss the deadline, file incorrectly, or avoid filing altogether — often because the process feels overwhelming. This guide breaks it down step by step.

Before You Start: What You'll Need

Filing your FBR return is much smoother if you have these ready:

• NTN (National Tax Number) — If you don't have one, register at iris.fbr.gov.pk
• CNIC or company registration documents — For identity verification on IRIS
• Audited accounts or management accounts — Income and expense records for the fiscal year (July 1 – June 30)
• Bank statements — For all business accounts used during the year
• List of fixed assets — If your business owns equipment, vehicles, or property
• Employee records — If you have salaried staff, you'll need their NTNs and salary data
• Prior year return — For reference, especially if you're filing for the second time or later

Step 1: Log Into FBR IRIS

IRIS (Integrated Revenue Information System) is FBR's online tax portal. All tax filing in Pakistan happens here.

1. Go to iris.fbr.gov.pk
2. Enter your NTN and password
3. If you've forgotten your password, use the "Forgot Password" option with your registered email or mobile number
4. If you're a first-time filer, use your NTN and CNIC to set up your account

Once logged in, you'll land on your IRIS dashboard.

Step 2: Navigate to the Income Tax Return

From the IRIS dashboard:

1. Go to Declaration in the top menu
2. Select Income Tax → Annual Return
3. Choose the tax year you're filing for (Tax Year 2025 covers July 1, 2024 – June 30, 2025)
4. Click Create or Edit if a draft was already auto-generated

IRIS will open the return form. It's divided into multiple sections — we'll go through each one.

Step 3: Business Income (Section — Business)

This is where you report your company's revenue and expenses for the year.

Income side:

• Enter total revenue from your business activities — sales, services, consulting fees, etc.
• If you have multiple income streams (local clients, foreign clients, rental income), they may go into different heads

Expense side: You can deduct allowable business expenses to reduce your taxable income. Common deductible expenses include:

• Employee salaries and benefits
• Office rent
• Utilities (proportional to business use)
• Business travel and transport
• Marketing and advertising costs
• Software subscriptions
• Professional services (accountant, lawyer fees)
• Equipment depreciation (under tax depreciation rates — not accounting depreciation)

Key point: You need your books to be in order before you can accurately fill in this section. If you've been tracking expenses in Asaan Hisaab throughout the year, you can export a categorized summary for the full fiscal year and use that directly.

Step 4: Capital Assets and Depreciation

If your business owns fixed assets — computers, vehicles, machinery, office equipment — you need to declare these in the return.

FBR uses a declining balance depreciation method with prescribed rates (for example, computers at 30%, vehicles at 15%, furniture at 10%). This is different from accounting depreciation, so the figures in your books and your tax return will differ.

List each asset with:

• Description
• Date of purchase
• Cost
• Written-down value (after prior year depreciation)
• Current year depreciation claim

Step 5: Bank Accounts and Cash in Hand

IRIS requires you to declare all bank accounts your business uses. For each account:

• Bank name
• Branch
• Account number
• Opening balance (July 1)
• Closing balance (June 30)

You'll also declare cash on hand at year-end. This must reconcile with your financial records.

Step 6: Employees and Withholding Tax

If you have employees, you're required to file withholding statements (on a quarterly basis during the year). In the annual return, you'll confirm:

• Number of employees
• Total salary paid
• Tax withheld and deposited

If you've been making monthly salary tax deposits through the IRIS e-payment system throughout the year, this section will largely be a confirmation.

Step 7: Reconciliation of Income with Bank Deposits

One section of the return asks you to reconcile your declared income with the total deposits into your business bank accounts during the year. This is designed to flag discrepancies.

Common differences that are normal and explainable:

• Loans received (deposits that aren't income)
• Capital introduced by the owner
• Bank transfers between your own accounts
• Advance payments that aren't yet earned revenue

Make sure your reconciliation is logical and you can explain any major gaps.

Step 8: Review and Verify

Before submitting, go through the return carefully:

• Check that income figures match your audited or management accounts
• Verify that all expenses are correctly categorized as deductible
• Make sure bank account balances match your statements
• Review the computed tax liability — does it look reasonable given your income?

Common errors to avoid:

• Forgetting to include income from a secondary bank account
• Claiming non-deductible personal expenses as business expenses
• Entering depreciation figures using accounting rates instead of FBR rates
• Leaving the capital account section blank (FBR will flag this)

Step 9: Pay Any Tax Owed

If your return shows a tax liability, you need to pay it before submitting.

FBR accepts tax payments through:

• 1-LINK PSID — Generate a Payment Slip ID from IRIS, then pay at any bank
• RAAST / Mobile Banking — Some banks allow direct payment using the PSID
• Bank branch payment — Physical payment at designated branches

Once paid, the payment will reflect in your IRIS account. Attach the payment challan to your return.

If you're entitled to a refund (for example, because withholding tax deducted by clients exceeds your liability), you can claim it in the return.

Step 10: Submit the Return

1. Click Verify — IRIS will run a validation check for obvious errors
2. Review any warnings and fix actual errors
3. Click Submit
4. You'll receive a confirmation with a unique return filing number — save this for your records

Your return is now filed. You can download a copy from IRIS at any time.

Key Deadlines to Remember

Missing the September 30 deadline results in a penalty of 0.1% of tax payable per day, subject to a minimum. File on time even if you're not sure everything is perfect — you can file a revised return later.

How Clean Books Make Filing Faster

The single biggest factor in how long FBR filing takes is whether your books are in order. If you've been tracking every expense and deposit throughout the year with the correct categories, pulling the numbers for your return takes a few hours. If you haven't tracked anything, it can take weeks.

Asaan Hisaab is designed for exactly this: logging every expense and deposit, locking closed months so no one can alter historical records, and giving you a clean summary at year-end that you can use directly for your tax return.

Frequently Asked Questions

What is the FBR tax filing deadline for businesses in Pakistan?

The annual income tax return for businesses is due on September 30. This covers the fiscal year from July 1 to June 30. Missing this deadline results in a daily penalty of 0.1% of tax payable. You can apply for a filing extension through IRIS, but it's not guaranteed.

What happens if I don't file my FBR return?

Non-filing results in a default notice from FBR, financial penalties, and eventually action under the Income Tax Ordinance. FBR has been expanding its documentation of the tax base — businesses that are registered but not filing are increasingly being flagged. Even if your tax liability is zero, you should file a nil return.

Do I need an audited account to file my return?

Private limited companies registered with SECP are required to have audited accounts. Sole traders and partnerships are not legally required to have an audit, but having organized management accounts (income summary, expense list, bank reconciliation) makes filing significantly easier and more accurate.

Can I file a revised return if I made an error?

Yes. You can file a revised return within five years of the original filing date. IRIS allows you to open your previous return and revise it. If the revision increases your tax liability, you'll need to pay the difference plus any applicable default surcharge.

What is the minimum tax for a business in Pakistan?

Pakistan has a minimum tax regime. Even if your business shows a loss or low profit, you may still owe minimum tax based on your turnover. The minimum tax rate varies by sector and business type. As of the 2025 tax year, check FBR's current rate schedule or consult a tax advisor for your specific sector.

What records do I need to keep after filing?

FBR can audit returns for up to five years. Keep all supporting documents — invoices, bank statements, payroll records, fixed asset details, and any expense receipts — for at least six years. If you're using accounting software like Asaan Hisaab, your transaction history is always accessible and timestamped, which makes producing records for an audit much faster.
