GST-free (or GST exemption) amounts vary significantly by context and country:
GST exemption from registration
A person whose turnover falls below the threshold exemption limit—INR 40 lakhs for goods, INR 20 lakhs for services, and INR 20 lakhs (or INR 10 lakhs in special category states) for specified categories.
If your GST turnover is below the $75,000 threshold, you may choose to register. But if you do, regardless of your turnover, you must: include GST in the price of most goods and services you sell. claim GST credits for most business purchases you make.
Example
To figure out how much GST was included in the price you have to divide the price by 11 ($110/11=$10); To work out the price without GST you have to divide the amount by 1.1 ($110/1.1=$100)
If a product is sold at Rs. 1,000 and the GST rate applicable is 18%, then the net price calculated will be = 1,000+ (1,000X(18/100)) = 1,000+180 = Rs. 1,180.
Subtracting GST from Price
To calculate how much GST was included in the price, divide the total price by 11 ($1000∕11=$90.91). To calculate the price without GST, divide the price by 1.1 ($1000∕1.1=$909.09).
Understanding GST Rate Reduction
Starting September 22, 2025, the GST Council reduced the number of tax slabs from four to two main rates: 5% merit rate for essential and priority items and 18% standard rate for most other goods and services. There is also a special 40% rate for luxury and sin goods.
How do you remove GST?
Net price = Original cost – GST
For example, if the cost of a product after GST of 18% is Rs. 118, its original cost is 118 – [100/(100 + 18%)}], which equates to Rs. 100.
You have to start charging GST/HST on the supply that made you exceed $30,000. You exceed the $30,000 threshold 1 over the previous four (or fewer) consecutive calendar quarters (but not in a single calendar quarter).
That means your take home pay will be $55,383 per year, or $4,615.25 per month. Your average tax rate is 20.88% and your marginal tax rate is 32.5%.
Businesses dealing in goods are exempt from GST if their annual aggregate turnover is below INR 40 lakhs. For businesses in hilly and northeastern states, this threshold is reduced to INR 20 lakhs to address regional challenges. Service providers are exempt from GST if their turnover is under INR 20 lakhs annually.
Small businesses in Australia who turn over less than $75,000 per year don't have to pay GST. If you're a registered not-for-profit, you also don't have to pay GST as long as your turnover is less than $150,000. If you run a taxi service or are an uber driver, for example, you must always pay GST, regardless of income.
GST Amount: ₹50,000 × 18% = ₹9,000. Total Amount: ₹50,000 + ₹9,000 = ₹59,000.
With the free GST calculator, you can calculate the tax amount in three simple steps. The tool provides you with three fields that have to be filled, and it calculates GST automatically based on what you fill in. Enter the price of the goods or services in the Amount field.
Example: If the pre-GST price is $100 and the GST rate is 10%, the GST amount is $100 x 10% = $10. Total price: To find the total price, add the GST amount to the pre-GST price: $100 + $10 = $110.
Barring of GST Return on expiry of three years
The GST network issued another advisory on 7th June 2025, implementing the rule of time-barring of GST return filing beyond three years from the due date. By this update, taxpayers will not be able to file GST returns after three years from the due date of such return.
The majority of food items fall under the 5% GST slab. However, under the GST 2.0 reform, restaurants within hotels are now classified as 'specified premises' and are subject to 18% GST. Standalone restaurants, on the other hand, can choose between charging 5% GST or 18% GST.
To add GST to a GST-exclusive price, multiply the base price by 1.1. For example, if a service costs $500 excluding GST, the total price is $500 × 1.1 = $550.
10,000 and the applicable GST rate is 18%. Hence Mr X (recipient of goods) has to pay Rs. 10,000 to the supplier/dealer and the GST amount of Rs. 1,800 has to be paid to the government by him.
