# CrestApps Taxation
Taxation (new in CrestApps.OrchardCore 3.0) is a provider-agnostic engine built on one principle: tax is a determination, not a property. Items carry only a classification; the engine determines taxes from what is sold, who buys it, where it is sourced, when, and how it is calculated, and returns auditable tax lines with the rule and table versions used.
## Where it fits in the commerce suite
| Module | Relationship |
| --- | --- |
| Commerce (`orchardcore-commerce`) | Required shell; **Commerce > Taxation** menu |
| Checkout (`orchardcore-checkout`) | Taxes the invoice through `ICheckoutTaxService` after discounts, and keeps a `TaxSnapshot`; tax profile handlers add origin, destination and exemptions |
| Products (`orchardcore-products`) | `ProductTaxableItemProvider` turns products into taxable items |
| Orders (`orchardcore-orders`) | Copies tax lines to `Order.TaxLines`; VAT OSS report |
| Subscriptions (`orchardcore-subscriptions`) | Re-taxes each renewal with the rules in effect |
| Customers (`orchardcore-customers`) | Tax-exempt customers and business tax ids |
