# About the Manual Tax Mappings API

The Manual Tax Mappings API allows you to enhance [Wix's manual tax calculator](fallback::https://support.wix.com/en/article/setting-up-tax-calculation-using-the-manual-method) by defining custom tax rates for specific combinations of [tax groups](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-groups/introduction) and [tax regions](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-regions/introduction). This API is designed for businesses that need to define and manage custom tax rates and mappings for calculating taxes with [Wix's manual tax calculator](fallback::https://support.wix.com/en/article/setting-up-tax-calculation-using-the-manual-method).

With the Manual Tax Mappings API, you can:
+ [Create](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/create-manual-tax-mapping) custom tax rate mappings for specific tax group and region combinations.
+ [Bulk create multiple tax mappings](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/bulk-create-manual-tax-mappings) for efficient setup and data imports.
+ [Retrieve](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/get-manual-tax-mapping) and [query](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/query-manual-tax-mappings) existing tax mappings by various criteria.
+ [Update](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/update-manual-tax-mapping) tax rates and associated details as regulations change.

This API is particularly useful for:
+ Businesses operating across multiple jurisdictions with complex tax requirements.
+ Companies importing tax rate data from external tax systems or spreadsheets.
+ Organizations that need to set custom rates.
+ Merchants with special tax arrangements or exemptions in certain regions.

## Before you begin

It's important to note the following before starting to code:

+ Prerequisites: Manual tax mappings require existing [tax groups](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-groups/introduction) and [tax regions](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-regions/introduction). You must create these entities in the [dashboard](fallback::https://support.wix.com/en/article/setting-up-tax-groups-using-manual-tax-calculation) or by using their respective APIs before creating mappings.
+ Tax group and region dependencies: Each manual tax mapping must reference existing tax group and tax region IDs. These entities define the scope where your custom tax rates will apply.
+ Decimal precision: Tax rates are specified as decimal values with up to 6 decimal places precision (for example, `0.085000` for 8.5%).
+ Bulk operations: Use bulk operations when setting up multiple mappings at once, such as during initial configuration or data imports. You can create up to 100 mappings in a single request.

## Use cases

Common scenarios for using the Manual Tax Mappings API include:

+ [Set up custom tax rates for a new region](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/sample-flows).
+ [Import tax mappings from an external system](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/sample-flows).
+ [Update tax rates after regulatory changes](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/sample-flows).

## Terminology

+ **Manual tax mapping**: A custom configuration for a specific tax group and region combination. Contains the custom tax rate and jurisdiction details.
+ **Tax group**: A collection of products or services that share the same tax treatment. Must be created using the [Tax Groups API](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-groups/introduction) before referencing in mappings.
+ **Tax region**: A geographical area where specific tax rules apply. Must be created using the [Tax Regions API](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-regions/introduction) before referencing in mappings.
+ **Tax rate**: The custom tax rate specified as a decimal value (for example, `0.080000` for 8%). Supports up to 6 decimal places for precision.
+ **Jurisdiction**: The governmental entity responsible for collecting the tax, such as a country, state, county, city, or special district.
+ **Tax type**: The category of tax being applied, such as VAT, GST, or Sales Tax, which depends on the jurisdiction's tax laws.

# Sample Use Cases and Flows

This article presents possible use cases and corresponding sample flows that you can support. This can be a helpful jumping off point as you plan your implementation.

## Set up custom tax rates for a new region

You need to configure tax rates for a business expanding into a new geographical region.

To set up custom tax rates for a new region:

1. Identify the tax groups that need custom rates in the new region. Call [Query Tax Groups](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-groups/query-tax-groups) to get the tax group IDs for products or services requiring different tax treatment.

1. Identify the tax region representing the new geographical area. Call [Query Tax Regions](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/tax-regions/query-tax-regions) to get the tax region ID.

1. [Create the manual tax mapping](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/create-manual-tax-mapping) with the custom rate.

1. Verify the mapping was created successfully by calling [Get Manual Tax Mapping](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/get-manual-tax-mapping) with the returned ID.

## Import tax mappings from an external system

You need to migrate existing tax configuration from a legacy tax system or import rates from a spreadsheet.

To import multiple tax mappings:

1. Structure your data as an array of manual tax mapping objects. Ensure each mapping has valid tax group and region IDs.

1. Group the mappings into batches of up to 100 items to comply with bulk operation limits.

1. For each batch, call [Bulk Create Manual Tax Mappings](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/bulk-create-manual-tax-mappings).

1. Process any failed mappings from the `results` array and retry them in a separate request if needed.

## Update tax rates after regulatory changes

Local tax authorities have announced rate changes that affect your existing manual tax mappings.

To update existing tax rates:

1. Query existing mappings that need updates. For example, to find all mappings for a specific region.

1. For each mapping that needs updating, call [Update Manual Tax Mapping](fallback::https://dev.wix.com/docs/api-reference/business-solutions/e-commerce/extensions/tax/manual-tax-mappings/update-manual-tax-mapping) with the new rate.

1. Verify the updates by querying the updated mappings to confirm the new rates are in effect.
