If you need proof of tax deducted on your Zong bill — for your income tax return, a withholding tax adjustment, or your records — here’s how to get it.
Why You’d Need a Zong Tax Certificate
Zong, like other telecom companies in Pakistan, withholds advance tax from your bill in accordance with the Income Tax Ordinance. If you are a tax filer, this is generally deductible against your annual tax liability, however it is important that you provide proof which is why a certificate is necessary.
How to Get It
Check your monthly bill first — Zong bills generally itemize the tax withheld per cycle, which may be sufficient documentation for small adjustments.
Request a consolidated certificate from Zong — for the entire tax year (all months), contact Zong customer support (call 310 from your Zong number, or contact via their helpline/app) and request a tax deduction certificate for your account. Have your CNIC and account/mobile number ready.
Check the Zong self-service app or portal — some telecom companies allow you to download a tax certificate directly from their app or online account portal, which might be much faster than contacting support.
What The Certificate Should Show
A correct tax certificate from Zong should show your account details along with the billing period for which tax was withheld. It should show the total amount billed, as well as the total advance tax withheld for the period, which you must reconcile against your IRIS return.
Using It On Your Tax Return
The advance tax withheld of your telecom bill will be reported and adjusted against your annual tax liability when filing your income tax return. Keep the certificate as a supporting document in case FBR asks you to substantiate the adjustment upon processing or a tax audit.
Common Issues
If Zong’s support is unable to find your deduction history, it is likely that you requested a certificate for an incorrect CNIC or mobile number — mismatches between your NTN/CNIC records and telecom account are the most likely cause of a failed certificate request.
