# Creating and Editing Tax Code Forms in Lucanet VAT

## Overview

In the **Tax code form** workspace in Lucanet VAT (Value Added Tax), you manage the forms of tax codes. VAT already contains standard forms, for example **MWS** for output tax and **VST** for input tax, which you can supplement with your own forms.

VAT identifies each tax code form via a three-character abbreviation that corresponds to the designation in the ERP system. You assign each form either to input tax or to output tax.

For transactions in which input tax and output tax arise at the same time, for example for intra-Community acquisitions or reverse charge cases, you assign a counter tax code form to a tax code form. In VAT, for example, the forms **ESA** and **ESE** are assigned to each other as counter forms.

Each [tax code](https://support.lucanet.com/en/documentation/income-taxes/vat/master-data/create-and-configure-tax-codes.md) belongs to a tax code form.

## Navigation to the 'Tax Code Form' Workspace in VAT

The **Tax code form** workspace can be found under **VAT | Master data | Tax code form** and is displayed as follows, for example:

![Shows the 'Tax code form' workspace in VAT with the 'Search' field, the 'Add' button, the three-dot icon, and the columns 'Tax code form', 'Tax type', 'Counter tax code form', 'Description', and 'Archived'. The table shows, for example, the tax code forms 'ESA' with the tax type 'Outputtax' and the counter tax code form 'ESE', 'ESE' with the tax type 'Inputtax' and the counter tax code form 'ESA', 'MWS' with the tax type 'Outputtax', and 'VST' with the tax type 'Inputtax'.](https://support.lucanet.com/assets/docs-images/income-taxes/vat/master-data/create-and-configure-tax-code-form/_images/en/overview-tax-code-form.png)

2. Fill in the fields. For a description of the fields, see the following table.

3. Click **Save**.

The following fields are available when you create and edit a tax code form:

| Field | Description |
|---------|---------|
| Tax code form | Specifies the abbreviation of the tax code form. The abbreviation must match the identifier in the ERP system exactly so that VAT imports the declaration values correctly. Exactly three characters without spaces are permitted. The field is mandatory. |
| Tax type | Assigns the tax code form to **Inputtax** or **Outputtax**. For tax codes of the output tax, VAT inverts the sign of the values during the import. The field is mandatory. |
| Counter tax code form | Assigns an already created tax code form with the opposite tax type. You only need the assignment if input tax and output tax always arise at the same time for the same transactions, for example for intra-Community acquisitions or reverse charge cases. |
| Description | Records additional notes on the tax code form as free text. The description is for information purposes only. |

## Editing a Tax Code Form in VAT
