# Ongoing Tax Updates

> How we manage global tax rate changes in real time.

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

We handle tax rate changes and jurisdictional updates through an automated, rule-based sync system. Changes are fetched, queued, and applied without downtime — so you always get the most current data in real-time API responses.

***

## Update System

Every tax change is stored in a structured update registry and processed automatically on schedule. Our sync engine checks for updates **every hour**, evaluates effective dates, and applies changes safely across global and regional tax databases.

## Update Schema

| Field                   | Description                                          |
| :---------------------- | :--------------------------------------------------- |
| `UpdateID`              | Unique identifier for each update                    |
| `ExecutionDate`         | Date when the update becomes effective               |
| `TypeOfUpdate`          | `Create New` or `Update Existing`                    |
| `TypeOfField`           | What changed — `Standard Rate`, `Special Rate`, etc. |
| `OldValue` / `NewValue` | JSON-encoded rate values                             |
| `ProductCategories`     | Affected product category IDs                        |
| `CustomerType`          | Targeted customer types (`B2B`, `B2C`, etc.)         |
| `JurisdictionID`        | Applicable jurisdiction(s)                           |

## Status Tracking

| Status        | Meaning                                   |
| :------------ | :---------------------------------------- |
| `Not Started` | Update is scheduled but not yet picked up |
| `In Process`  | Update is being executed                  |
| `Completed`   | Change has been applied to live APIs      |
| `Error`       | Execution failed; retried automatically   |

## Developer Notes

* No action is needed on your end — all updates are reflected automatically in `/v1/tax/rate` and `/v1/tax/unify`.
* Backdated updates apply retroactively for audit/reporting workflows.
* Syncs are designed for **zero downtime** and **idempotent processing**.
