You file your sales tax return. It shows Rs 10 million in sales. Then you file your income tax return. It shows Rs 6 million in revenue. Same business, same year, two different numbers. FBR sees both returns. And FBR notices gaps.
The facts, in short
- Sales tax is charged on taxable supplies at the time of supply.
- Income tax is charged on profit, recognizing revenue when earned.
- The gap comes from exempt sales, zero-rated supplies, returns, timing differences, and unrecorded cash.
- FBR compares them. Cross-referencing is now routine — and mismatches trigger notices.
Why the two returns never match
Sales tax and income tax are different taxes with different rules. They are not supposed to match perfectly — but a large, unexplained gap is a red flag.
- Exempt supplies. Some sales are exempt from sales tax but still count as income for income tax purposes. The reverse can also happen.
- Zero-rated supplies. Exports and certain supplies are zero-rated for sales tax. They still generate income.
- Sales returns. A customer returns goods. You may adjust sales tax in one month and income tax in another.
- Timing differences. Sales tax is accounted when the invoice is issued. Income tax recognizes revenue when earned — which may be a different period.
- Cash sales never invoiced. Money in the bank that never went through the sales tax system but shows up as bank deposits.
What FBR does with the gap
FBR's computer systems now cross-reference sales tax and income tax declarations. When the numbers diverge significantly, the system flags it. The result is often a notice asking you to explain the difference — and if you cannot, FBR may treat the higher figure as your true income and assess tax accordingly.
This is how honest businesses end up with unexpected tax bills. Not because they evaded tax, but because their two returns told different stories and nobody reconciled them.
How to reconcile them
- Start with sales tax sales. Take the total taxable supplies from your sales tax return.
- Add exempt and zero-rated supplies. These are sales that are income but outside sales tax.
- Subtract sales returns. Adjust for returns handled differently in each return.
- Adjust for timing. Move sales between periods where sales tax and income tax recognize them differently.
- Compare to income tax revenue. The reconciled figure should match — or the difference should be fully explained.
Can you file revised returns?
Yes — both sales tax and income tax returns can be revised within the allowed time. But do not revise just to make the numbers match. Understand why they differ first. Random revisions without explanation create more questions than they answer.
Stop guessing. Get your tax reconciled.
We will reconcile your sales tax and income tax returns, document every adjustment, and make sure FBR never has a reason to send you a notice.
Frequently asked questions
Why do my sales tax and income tax returns show different sales?
They measure different things. Sales tax is charged on taxable supplies; income tax is charged on profit. Exempt sales, zero-rated supplies, returns, and timing differences create gaps.
Does FBR compare the two returns?
Yes. FBR's systems cross-reference sales tax and income tax declarations. Unexplained mismatches trigger notices.
How do I reconcile them?
Start with sales tax sales, adjust for exempt/zero-rated supplies and returns, adjust for timing, then compare to income tax revenue. Document every adjustment.
Can I file revised returns to fix the gap?
Yes within the allowed time — but only after understanding why the gap exists. Random revisions create more questions than answers.
