Tax Engine
The library of tax rules InEx can apply.
What is the Tax Engine screen?
Tax Engine is the library of tax rules InEx can apply to transactions — GST/IGST/CGST rates, Income Tax slabs, Reverse Charge Mechanism (RCM) rules, MAT, and Corporate Tax rates — each scoped by country, transaction type, and sender/receiver.
Why does this matter?
Tax rules change by country, transaction type, and counterparty. Keeping them as reusable rules means you set them up once and apply them consistently rather than calculating tax by hand on every transaction.
When would I use this?
- Setting up your tax rules before you start recording taxable transactions
- Adding a new tax rate or rule (e.g. a new RCM category)
- Reviewing which rules are currently Active
Before you start
You need access to the Tax Engine screen under Finance → Inex, and a clear understanding of which rates legally apply to your business — check with your accountant if you're unsure.
Reading the stats
| Item | Meaning |
