When sales, not profit, decide your tax bill
For a high-volume, low-margin business in Pakistan, the most dangerous tax surprise is not the rate on profit. It is section 113 of the Income Tax Ordinance, the minimum tax on turnover. The Federal Board of Revenue (FBR) uses it to stop businesses with enormous sales and razor-thin reported profits from paying almost nothing. The rule is blunt: you compute tax the normal way on profit, you compute a minimum tax on total turnover, and you hand over whichever is larger. This calculator exists to show you, before the year closes, which of those two will actually apply to you.
The percentages move with each Finance Act, so read the figures here as the ones this calculator currently applies and confirm your tax year's position with the FBR. The mechanism itself, a floor pegged to revenue, has been a fixture of Pakistani company taxation for years and is safe to plan around.
The distributor's problem in numbers
Picture a trading company, a distributor or fuel retailer, the kind of business that moves a lot of stock on a slim spread. Using the tool's defaults, it turns over PKR 150 million in a year but, after thin margins and a tough season, reports taxable profit of just PKR 5 million. Run the two tests at the rates this calculator applies. Normal tax for a standard company is 29% of PKR 5 million, which is PKR 1.45 million. The minimum tax is 1.25% of the full PKR 150 million turnover, which is PKR 1.875 million. The minimum is higher, so that is the bill. The effective tax on its actual profit works out to roughly 37.5%, far above the headline 29%, purely because revenue was large relative to profit.

Finding the profit where the floor lifts off
The minimum tax does not always bite. There is a crossover point: as profit rises, normal tax eventually overtakes the turnover floor and the minimum stops mattering. For this same distributor on PKR 150 million of sales, the floor is fixed at PKR 1.875 million. Normal tax reaches that level when 29% of profit equals PKR 1.875 million, which is a profit of about PKR 6.47 million. Below that profit the floor wins; above it, normal tax wins. Push the example to a healthier year with PKR 12 million of profit and normal tax becomes PKR 3.48 million, comfortably above the PKR 1.875 million floor, so the minimum tax becomes irrelevant. Knowing your crossover profit tells you exactly how lean a year has to get before turnover tax starts to hurt.
The chart traces both tests as profit climbs. The flat dashed band is the turnover floor; it does not change with profit. The rising bars are normal tax. Where the rising line passes the floor is your crossover.
Standard versus small company changes the threshold
The company type toggle reshapes the whole comparison. A small company is taxed on profit at 20% as modelled here, against 29% for a standard company, while the turnover floor stays at the same 1.25%. A lower profit rate means normal tax is smaller for any given profit, so the turnover floor wins more often and the crossover profit sits higher. In other words, qualifying as a small company helps your profit rate but makes you more likely to be caught by the minimum on a thin-margin year. Confirm with the FBR whether your business meets the small-company conditions on capital, employees, and turnover, because they are strict.
Who this tool is built for, and its limits
This calculator is aimed at owners and finance staff of trading, distribution, and other turnover-heavy companies who need to know during the year whether the minimum tax will apply, so they can fund the right advance-tax instalments. It reports only the income tax line from this single comparison. It does not layer on super tax for very large incomes, the Workers' Welfare Fund, or sales tax, all of which are separate. Use it to see which test governs you, then have a tax professional confirm classification and the current rates before filing.
What exactly counts as turnover for this calculation?
Turnover here means gross receipts or sales for the year, not profit and not the amount left after costs. That is precisely why a low-margin business can owe more under the floor than under normal tax: the base is the whole top line. Some receipts and certain sectors have specific treatment under FBR rules, so confirm what is included for your business rather than assuming every rupee of inflow counts.
Are any businesses exempt from minimum turnover tax?
Certain categories and start-up periods can be relieved or charged at reduced rates under the law, and these reliefs are revised by the FBR from time to time. This calculator applies the standard 1.25% across the board, so if you believe your sector qualifies for an exemption or a lower rate, verify the current schedule before relying on the number shown here.
