# TAX\_REFUND

{% hint style="info" %}
`POST /api/finance/process-document/TAX_REFUND`

`POST /api/finance/process-document/TAX_REFUND?preview`

**?preview parameter**

If `preview` is passed then no ledger posting, tax ledger entries, or persisted records are created. The response shape is identical to a live request.
{% endhint %}

The TAX\_REFUND endpoint records a refund received from a tax authority.

### Request Object

This request object has the following notable properties:

* A single tax authority per document is supported.
* The tax side posts to the configured `TAX_ON_PURCHASES` tax control account.
* The bank / cash side is resolved from the selected Bank / Cash account.
* If `bank_cash_account_code` is omitted, the configured document default Bank / Cash account is used.
* If `bank_cash_account_code` is supplied, it overrides the document default and must identify a valid active Bank / Cash account code.
* Bank / cash details are supported.
* No AR or AP Subledger movement is created.

## Financial / Ledger Treatment Principles

### Journal treatment

The engine debits the selected Bank / Cash account and credits the tax GL account.

```txt
  TAX_REFUND

  Ledger (typical use case):

  Dr Bank / cash
    Cr TAX_ON_PURCHASES

  BY WAY OF:

    Voyzu journal:
      Dr selected Bank / Cash account
        Cr TAX_ON_PURCHASES Control Account
```

### Posting Code Slots

The tax side does not provide a caller-supplied posting code slot or GL override.

The tax side always resolves through the configured `TAX_ON_PURCHASES` tax control account.

### Bank / Cash account selection

| Slot name                | Scope  | Description                                                                                                                       |
| ------------------------ | ------ | --------------------------------------------------------------------------------------------------------------------------------- |
| `bank_cash_account_code` | Header | Optional Bank / Cash account code used to select the refund bank/cash posting target. If omitted, the configured default is used. |

### Tax Ledger treatment

TAX\_REFUND creates a credit movement in the Tax Ledger against the supplied tax authority.

```txt
Tax Ledger Treatment:

  TAX-30000
    Document: TAX_REFUND TAX-REF-1001
    Tax authority: IRD
    Tax movement: Tax on Purchases
    Debit: -
    Credit: 1,000.00
    Effect: records tax refunded by the authority
```

### Inventory treatment

TAX\_REFUND has no inventory implications and creates no Inventory Ledger entries.

### Date treatment

`refund_date` must be supplied. `posting_date` may be supplied. If not supplied, `posting_date` defaults to `refund_date`.

### Bank Details

TAX\_REFUND supports Bank / Cash details.

If `bank_cash_account_code` is omitted, the configured TAX\_REFUND Bank / Cash account default is used. If supplied, `bank_cash_account_code` overrides the default and must identify a valid active Bank / Cash account code. Voyzu resolves the selected Bank / Cash account to its linked GL account.

If `bank_cash_details` is supplied, it records transaction/reference details for the selected Bank / Cash account.

### Dimensions treatment

TAX\_REFUND does not support dimensions. If dimensions are supplied, the transaction is rejected.

## Use cases

### Receive a tax refund

```txt
Ledger:

  TAX_REFUND TAX-REF-1001

  Dr Bank / cash                 1,000.00
    Cr Tax on Purchases - Recoverable 1,000.00

  BY WAY OF:

    Voyzu journal:
      Dr BANK_OPERATING                          1,000.00
        Cr TAX_ON_PURCHASES Control Account      1,000.00

Tax Ledger Treatment:

  TAX-30000
    Document: TAX_REFUND TAX-REF-1001
    Tax authority: IRD
    Tax movement: TAX_ON_PURCHASES
    Debit: -
    Credit: 1,000.00
    Effect: records tax refunded by the authority
```

## Considerations

* TAX\_REFUND records settlement activity, not AR/AP source tax.
* Refunds are received from one tax authority per document.
