# Ongoing Tax Updates

> How Antei keeps your tax engine up to date with global changes using automated workflows.

<Icon icon="rotate" size={26} color="#4B5563" />

Antei's tax platform maintains **real-time accuracy** through a robust and automated update system. Our approach ensures tax rate changes, jurisdiction-level rules, and compliance updates are handled in a structured, timely, and fully auditable manner — without manual intervention or business disruption.

## How It Works

Every hour, a background sync job checks for new tax-related updates across supported countries and jurisdictions. These updates are queued, validated, and then automatically applied within the system — including country, jurisdiction, and county-level rules.

***

## Update Structure

Each tax update is stored and processed based on a standardized structure:

| Field                    | Description                                                                   |
| :----------------------- | :---------------------------------------------------------------------------- |
| `UpdateID`               | Unique identifier for the update event                                        |
| `ExecutionDate`          | Scheduled execution date (in UTC)                                             |
| `ExecutionTime`          | Timestamp (in ms) for when execution will occur                               |
| `TimeZone`               | Timezone offset (in minutes) for the jurisdiction                             |
| `TypeOfUpdate`           | `Create New` or `Update Existing`                                             |
| `TypeOfField`            | Field being modified — `Standard Rate`, `Special Rate`, or `Additional Taxes` |
| `OldValue`               | JSON object storing the previous value                                        |
| `NewValue`               | JSON object storing the new value                                             |
| `ProductCategories`      | List of internal category IDs affected by this update                         |
| `ProductDeliveryMethods` | Delivery method types affected (e.g., `CLOUD`, `PHYSICAL`)                    |
| `CustomerType`           | Array of customer types the rule applies to (e.g., `B2B`, `B2C`)              |
| `CountryID`              | Internal reference to the affected country                                    |
| `JurisdictionID`         | One or more jurisdiction references affected                                  |
| `CountyID`               | Optional — applies if county-specific overrides exist                         |

***

## Execution Lifecycle

Each update follows a structured lifecycle:

| Status        | Description                                                               |
| :------------ | :------------------------------------------------------------------------ |
| `Not Started` | Update is registered but not yet queued for execution                     |
| `In Process`  | The update is currently being applied to the system                       |
| `Completed`   | Successfully executed and reflected in live tax APIs                      |
| `Error`       | Logged for review if execution fails — retried automatically with backoff |

We track `StartTime`, `EndTime`, and `ProcessingTime` to ensure transparency and operational monitoring.

***

## Auditability & Governance

* All updates are stored immutably with timestamps.
* Audit logs record changes at the field level.
* Failures are isolated and do not affect system availability.
* Rollbacks are supported in the rare event of downstream impact.

***

## Use Cases

* Jurisdiction introduces a **new digital services tax**
* Country increases **standard VAT rate**
* Special tax holiday applied at **county level**
* Regulatory notice affecting **B2B exemptions**

These updates are handled behind the scenes — no manual intervention or app downtime required.
