Frequently asked questions

Is WHT charged on service payments from the first rupee?
Once the Rs. 100,000-per-month threshold is met, 5% applies to the full payment. Below the threshold, no WHT is withheld.
Which withholding taxes are final and which are creditable?
Dividend WHT (15%) is a final tax. Interest AIT (10%), rent WHT (10%) and service WHT (5%) are creditable against your return.
