InvUltra prints a tax line on invoices and quotes. It does not submit a sales-tax or income-tax return. Filing on a government portal stays outside this app.
Steps
- Open Settings, then Tax & Finance.
- Turn Enable Tax System on. Turn it off to stop tax on new invoices and quotes.
- Set Tax 1 name (for example GST) and the rate percent.
- Choose Tax Exclusive when tax is added on top of the price. Choose Tax Inclusive when the shelf price already contains the tax.
- Turn on Secondary Tax only if you need a second line, then name it and set its rate.
- Save, then open a draft invoice and confirm the tax line.

A customer can be marked tax exempt on their record. See Customers.
