FBR Compliance: STRN-registered businesses must issue tax invoices showing STRN, NTN, tax amount, and rate. Invoices without these details are not eligible for input tax credit.
If you are a registered taxpayer (STRN holder), every taxable supply must be supported by a proper tax invoice. Without it, your buyer cannot claim input tax credit.
