# Withholding Tax On Payment

Create and manage **Withholding Tax (WHT)** documents linked to **Payments**

Includes WHT certificate printing, XLSX export, tax section support, and company-based sequence management.

## Overview

This module extends the standard withholding tax workflow by linking **Withholding Tax documents** directly to **Payments**. It helps accounting teams manage WHT certificates more efficiently, with support for confirmation checks, document numbering, report printing, and XLSX export.

### Why use this module?

- Manage WHT certificates directly from payment records
- Keep withholding tax documents organized and traceable
- Print official WHT certificates in PDF format
- Export certificate data to XLSX using a predefined template

## Key Features

- Adds a dedicated Withholding Tax document model
- Links WHT documents with account.payment
- Opens related WHT documents directly from Payment form
- Supports WHT Payment options
- Adds Tax Section field in wizard, payment, and WHT form
- Requires Other field for specific tax sections
- Company-based WHT sequence generation
- Confirmation allowed only when payment is paid
- QWeb PDF certificate report
- XLSX export with template-based output

## How it works

- Create a payment from Vendor Bill / Invoice using **Register Payment**
- Fill withholding tax lines and select the proper **Tax Section**
- Confirm payment as usual
- The system automatically creates a linked **Withholding Tax document**
- Users can print the certificate or export it to XLSX later

### Supported WHT Payment Types

| Code | Description |
| --- | --- |
| (1) | Withheld at source |
| (2) | Issued for life |
| (3) | One-time issuance |
| (4) | Others |

The module helps standardize withholding tax processing from payment creation to certificate output.

## Configuration

1. Go to **Settings → Accounting**
2. Configure **Withholding Tax Sequence** for each company
3. Open Vendor Bill / Invoice and click **Register Payment**
4. Fill withholding tax lines in the payment register wizard
5. Set the correct **Tax Section** and WHT Payment type
6. Confirm the payment

If no WHT sequence is defined, the system can automatically create one during confirmation.
