Do you know how the government manages to build roads, run schools, or offer public services? The answer is simple taxes. People and businesses pay these required amounts to the government, which then uses the funds to improve the country and care for its citizens. Understanding taxes helps us see how a country grows, functions, and supports its citizens, making it an essential topic for everyone to learn.

What are Taxes?

Taxes such as Sales Tax, Value Added Tax, and Goods and Services Tax are amounts added to the Price of goods and services. The government imposes these taxes on businesses and individuals to help fund public welfare and development activities.

These taxes are included in many bills, where the total amount is calculated by adding the tax to the product or service's original price.

A person who pays tax to the government is called a taxpayer, while the one who collects tax on the government's behalf is known as a tax collector.

There are different types of taxes, and each type is calculated using a different formula. For example, sales tax is calculated by using this formula.

Formula:
\(Sales Tax = Cost Price × Tax Rate\)

Total Price Formula

\(Total Price = Cost Price + Sales Tax\)

For example: A restaurant charges $60 for a meal. The GST (tax) applied on the bill is 18%. What is the total bill amount?

Solution:
Cost of meal = $60

GST rate = 18%

For $100, GST charged = $18

For $1, GST charged = \(\frac{18}{100}\)
 ​
For $60, GST is charged.

= \(\frac{18}{100} \times 60\)

= \($10.80 \)
Therefore, the total bill amount will be:

\(Bill = Cost + GST\)

\(= 60 + 10.80 = $70.80\)

What are the Types of Taxes?

There are two types of taxes based on the type of payment: direct and indirect taxes. Direct taxes are the taxes paid by individuals directly to the government such as income tax, wealth tax, gift tax, capital tax, etc.

A book is sold for $50 with a 5% tax rate. Calculate the tax amount.

Okay, lets begin

The tax amount is $2.50
 

Explanation

The price of the book (S.P) = \($50\)

The tax rate = \(5\%\)

Tax amount = \(\frac{\text{S.P.} \times \text{tax rate}}{100}\)

\(= {{{{50 × 5 }} \over {{100}} }}= 2.5\)

So the tax amount = \($2.5\)

Problem 2

A meal costs $25, and the restaurant charges 8% tax. How much is the tax?

Okay, lets begin

The amount of tax on the meal is \($2\)
 

Explanation

The price of the meal (S.P) = \($25\)

The tax = \(8\%\)

Tax amount = \({{S.P. × {\text{tax rate}} }}\over 100\)

= 25 × 8 / 100 = 2

The amount of tax on the meal = $2

Problem 3

A student pays a $5 tax on a $100 book. What is the tax rate?

Okay, lets begin

The tax rate is 5%
 

Explanation

Problem 4

A gaming laptop has a 10% tax rate and a pre-tax price of $1500. Find the total price.

Okay, lets begin

The total price of the laptop = $1650
 

Explanation

The pre-tax price of the laptop = $1500

The tax rate = 10%

Tax amount = S.P. × tax rate / 100

= 1500 × 10 / 100 = 150

The amount of tax on the laptop = $150

So, the total price of the laptop = Tax amount + pre-tax price 

= 1500 + 150 = 1650


Thus, the price of the laptop =  $1650

Problem 5

The price of a backpack is $45 with an 8% tax. Find the tax amount and total price.

Here, S.P. = $45

Tax rate = 8%

= 45 × 8 / 100 = 3.6

The tax amount is $3.6

The price of the backpack is S.P + tax amount 

= 45 + 3.6 = 48.6
