Frequently Asked Questions
What is the standard sales tax rate in Pakistan?
The standard general sales tax (GST) rate in Pakistan is 17% on most goods, though specific categories can have different rates set by the FBR and provincial revenue authorities.
How do I remove GST from a total to find the base price?
Switch to 'Remove GST' mode and enter the tax-inclusive total — the calculator divides by (1 + rate/100) to find the net amount and shows the GST portion separately.
Can I use this for VAT calculations too?
Yes, the underlying math for adding or removing a percentage-based tax is the same for VAT, GST, or general sales tax — just select or type in the correct rate.
