Sales tax and GST in plain terms
A sales tax (called GST — General Sales Tax — in Pakistan) is a percentage added to the price of goods and services at the point of sale. The shop collects it from you and passes it to the government. Pakistan's standard GST on goods is 18%, administered by the FBR, while services are taxed provincially — Sindh, Punjab, KP and Balochistan each set their own rates, typically between 13% and 16%. Registered businesses can usually offset the tax they paid on inputs against the tax they collect, which is why separating tax from price matters so much in bookkeeping.
How to use this calculator
Enter the amount and the rate. In Add tax mode, the amount is a pre-tax price and the tool shows the tax and final total — what a customer will actually pay. In Price includes tax mode, the amount is a tax-inclusive total (like most shop receipts) and the tool extracts the original price and the tax hidden inside it.
The formulas
Extract: price = total ÷ (1 + rate ÷ 100)
Worked example
A shopkeeper buys stock worth PKR 5,000 ex-tax. With 18% GST: tax = 900, total payable = PKR 5,900. Later, checking a receipt that shows only a grand total of PKR 5,900, the extract mode recovers the pre-tax price: 5,900 ÷ 1.18 = PKR 5,000, tax PKR 900 — the amount the business can claim as input tax if registered. The common mistake — taking 18% of 5,900 (= 1,062) — overstates the tax by PKR 162.
When is this useful?
Small businesses pricing products ("what must I charge so the sticker price covers 18%?"), buyers checking whether a quoted price is inclusive or exclusive, freelancers adding provincial services tax to invoices — our invoice generator applies the rate automatically — and anyone reconciling receipts for accounts. For foreign VAT-style rates, the VAT calculator is the same maths with international presets in mind.
Frequently asked questions
What is the sales tax rate in Pakistan?
The standard GST on goods is 18% (federal). Services are taxed by the provinces at their own rates, commonly 13% (Sindh), 16% (Punjab) — rates change with budgets, so verify current figures with FBR or your provincial revenue authority.
Is GST the same as income tax?
No. GST is a consumption tax on what you buy or sell; income tax is charged on what you earn. A business may deal with both — GST on sales and income tax on profits.
How do I know if a price already includes tax?
Retail shelf prices in Pakistan are usually tax-inclusive; business quotations are often ex-tax. When it matters, ask — and use the 'Price includes tax' mode to split an inclusive total.
Do small sellers have to charge GST?
Only registered businesses charge and remit GST; registration is mandatory above turnover thresholds and for certain sectors. An unregistered corner shop's prices simply include the tax it paid its suppliers.
Why is my extracted tax different from rate × total?
Because the rate applies to the pre-tax price, not the total. On a PKR 5,900 inclusive total at 18%, the tax is 900 (18% of 5,000) — not 18% of 5,900.
