UK Tax Code validator
=====================

[](#uk-tax-code-validator)

This package is for validating if a UK tax code is valid.
As there are many rules for when a UK tax code is valid, we needed a way to actually check this. This package contains all the rules for validating if the UK tax code is a valid or not.

Usage
-----

[](#usage)

For validating a tax code, you can simply run the following

```
$engine = new Engine();
$response = $engine->validate($taxCode);

$response->isValid();
```

### Laravel

[](#laravel)

The package does also contain a validation rule to be used with Laravel.

```
Validator::make($data, [
    'tax_code' => ['required', new UkTaxCode(),],
])->fails();
```
