# GST tax invoices and GSTIN

Every payment by a business **in India** comes with a **GST tax invoice**. Paying from outside India? Your invoice is in US dollars without Indian GST; see [paying from outside India](/billing/paying-from-outside-india).

## Download an invoice

1. Open **Billing**.
2. Under **Transactions**, click the invoice number next to the payment.
3. Download or print it as a PDF.

## Add your GSTIN

To claim **input tax credit**, add your business's GSTIN at checkout:

1. Tick **I need a GST invoice for my business**.
2. Enter your 15-character **GSTIN**. We check the format and check digit as you type and show the state it belongs to.
3. Enter your **registered business name** exactly as on your GST certificate. It is required whenever a GSTIN is entered.

Your GSTIN and business name then appear on your invoices.

## CGST + SGST or IGST?

The tax split depends on the **place of supply**:

- If your GSTIN (or, without a GSTIN, your billing state) is in the same state as ours, the invoice shows **CGST + SGST**.
- Otherwise it shows **IGST**.

The total you pay is the same either way, because plan prices include 18% GST.
