GST Calculator India — Invoice GST for Freelancers & Small Business

Split GST on invoices in India: exclusive vs inclusive GST, common rates (5/12/18/28), freelancer basics, and how to use our free GST calculator.

GST on everyday invoices

Freelancers and small businesses constantly split GST at common rates (5%, 12%, 18%, 28%). Mistakes show up as awkward client conversations and messy books. A calculator helps you quote cleanly — registration and filing still happen only on the GST portal.

Exclusive vs inclusive — worked intuition

Exclusive example: base ₹10,000 at 18% adds ₹1,800 → total ₹11,800. Inclusive mode starts from the total and recovers base + tax. Always state which mode you used on the quote.

Freelancer checklist (educational)

Know whether you must register based on turnover thresholds (confirm current law officially). Keep GSTIN on invoices when registered. Separate tax collected from money you can spend. This is not tax advice — thresholds and composition scheme rules change.

Frequently asked questions

What is exclusive vs inclusive GST?

Exclusive: tax is added on top of the base. Inclusive: the total already contains GST and you reverse-calculate the base. Know which mode your invoice uses.

Does this tool file GST returns?

No. Use the official GST portal for registration, GSTR filing, and official computations. Our calculator is for quotes and invoice checks only.
