which type tax is calculated on a per item basis

The type of tax that is calculated on a per-item basis is called "excise tax." Excise taxes are typically levied on specific goods or activities, such as tobacco, alcohol, gasoline, luxury goods, or certain licenses. These taxes are imposed at a fixed rate or as a percentage of the item's price and are paid by the producer or supplier. The amount of excise tax is determined by multiplying the tax rate by the quantity or value of the item being taxed. To find out if a particular item is subject to excise tax and the specific rate, you can refer to your local tax laws, government websites, or consult a tax professional.
