A Surprising Story: The Freelancer's First Invoice

Riya, a freelance graphic designer, landed her first big project. She quoted the client ₹50,000 for her services. The client agreed but asked for a proper invoice including GST. Riya had no idea how to calculate it. She found a GST calculator and entered her amount. She was surprised to see that adding 18% GST meant her total invoice amount would be ₹59,000.

Later, she received a bill from a vendor for a new software subscription for ₹11,800, which was "inclusive of GST". Using the calculator again, she switched to the "Including GST" option and found that the actual cost of the software was only ₹10,000, and she had paid ₹1,800 in tax. This simple tool demystified GST for her. It not only helped her create accurate invoices for her clients but also made her understand the true cost of her business expenses, allowing her to claim input tax credit correctly. It was a small discovery that made a huge impact on her business finances.

FAQs

What is GST?

GST, or Goods and Services Tax, is an indirect tax used in India on the supply of goods and services. It is a comprehensive, multi-stage, destination-based tax that has replaced many indirect taxes in India.

What are CGST, SGST, and IGST?

For intra-state transactions, the GST is divided equally into Central GST (CGST) and State GST (SGST). For inter-state transactions, a single Integrated GST (IGST) is charged. The total tax rate remains the same (e.g., an 18% slab is 9% CGST + 9% SGST for intra-state, or 18% IGST for inter-state).

What are the different GST slabs in India?

Currently, there are four main GST slabs in India: 5%, 12%, 18%, and 28%. Some essential goods have 0% GST, while a special rate of 3% applies to gold, jewellery, and precious stones.
