How to Make a Tax Invoice Online in India

A tax invoice in India is a specific type of invoice issued for taxable goods or services, showing GST separately from the value of the supply. Here's how to create one correctly, online, for free.

What Makes an Invoice a "Tax Invoice" in India

Under GST rules, a valid tax invoice should include:

• Invoice number and date — unique and sequential
• Supplier details — name, address, and GSTIN (GST registration number)
• Recipient details — name, address, and GSTIN if the recipient is also registered
• HSN/SAC code for the goods or service
• Description, quantity, and value of goods/services
• Taxable value and the GST rate applied (CGST + SGST, or IGST for inter-state supply)
• Total invoice value, including tax
• Place of supply, especially for inter-state transactions

Missing GSTIN, HSN/SAC codes, or a clear tax breakdown are the most common reasons a tax invoice gets rejected by a client's accounts team or flagged during a GST audit.

Step-by-Step: Creating a Tax Invoice Online

• Open Simple Invoice Maker — no installation, works in your browser.
• Enter your business details, including your GSTIN, so it appears on every invoice.
• Add the client's details and their GSTIN if they're a registered business.
• Add line items with description, quantity, and rate — apply the correct GST rate per item or overall.
• Review the tax breakdown — the subtotal, GST amount, and total are calculated automatically so you don't have to compute CGST/SGST/IGST by hand.
• Download the PDF and send it via email or WhatsApp, or print it for the client.

CGST/SGST vs IGST — Which Applies?

• CGST + SGST apply when the supplier and recipient are in the same state.
• IGST applies when the transaction is inter-state (supplier and recipient in different states).

Getting this split wrong is a common compliance mistake — always confirm the recipient's state before finalizing the invoice.

Tips for GST-Compliant Invoicing

• Keep invoice numbering sequential and unbroken — gaps can raise questions during an audit.
• Double-check the GST rate for your specific goods/service category — rates vary (0%, 5%, 12%, 18%, 28%).
• Save your GSTIN and standard tax rate once in Settings so it's applied consistently across invoices.
• Retain copies of every tax invoice issued — sign in and your invoice history is saved automatically under My Invoices.
