In order to install the VAT Calculator, just run
$ composer require mpociot/vat-calculatorThis package comes with a service provider, to use this package within your Laravel 5 app. Go to your config/app.php and add
Mpociot\VatCalculator\VatCalculatorServiceProvider::class
to the providers array.
The VatCalculator Facade will be installed automatically within the Service Provider, but if you want you can of course add it to the aliases array (Useful for the IDE helper).
'VatCalculator' => Mpociot\VatCalculator\Facades\VatCalculator::class
You can also use this package without Laravel. Simply create a new instance of the VAT calculator and use it. All documentation examples use the Laravel 5 facade code, so make sure not to call the methods as if they were static methods.
Example:
use Mpociot\VatCalculator\VatCalculator;
$vatCalculator = new VatCalculator();
$vatCalculator->setBusinessCountryCode('DE');
$countryCode = $vatCalculator->getIPBasedCountry();
$grossPrice = $vatCalculator->calculate( 49.99, 'LU' );To calculate the gross price use the calculate method with a net price and a country code as paremeters.
$grossPrice = VatCalculator::calculate( 24.00, 'DE' );The third parameter is the postal code of the customer.
As a fourth parameter, you can pass in a boolean indicating whether the customer is a company or a private person. If the customer is a company, which you should check by validating the VAT number, the net price gets returned.
$grossPrice = VatCalculator::calculate( 24.00, 'DE', '12345', $isCompany = true );After calculating the gross price you can extract more information from the VatCalculator.
$grossPrice = VatCalculator::calculate( 24.00, 'DE' ); // 28.56
$taxRate = VatCalculator::getTaxRate(); // 0.19
$netPrice = VatCalculator::getNetPrice(); // 24.00
$taxValue = VatCalculator::getTaxValue(); // 4.56Prior to validating your customers VAT numbers, you can use the shouldCollectVAT method to check if the country code requires you to collect VAT
in the first place.
if (VatCalculator::shouldCollectVAT('DE')) {
}To validate your customers VAT numbers, you can use the isValidVATNumber method.
The VAT number should be in a format specified by the VIES.
The given VAT numbers will be truncated and non relevant characters / whitespace will automatically be removed.
This service relies on a third party SOAP API provided by the EU. If, for whatever reason, this API is unavailable a VATCheckUnavailableException will be thrown.
try {
$validVAT = VatCalculator::isValidVATNumber('NL 123456789 B01');
} catch( VATCheckUnavailableException $e ){
// Please handle me
}To get the details of a VAT number, you can use the getVATDetails method.
The VAT number should be in a format specified by the VIES.
The given VAT numbers will be truncated and non relevant characters / whitespace will automatically be removed.
This service relies on a third party SOAP API provided by the EU. If, for whatever reason, this API is unavailable a VATCheckUnavailableException will be thrown.
try {
$vat_details = VatCalculator::getVATDetails('NL 123456789 B01');
print_r($vat_details);
/* Outputs
stdClass Object
(
[countryCode] => NL
[vatNumber] => 123456789B01
[requestDate] => 2017-04-06+02:00
[valid] => false
[name] => Name of the company
[address] => Address of the company
)
*/
} catch( VATCheckUnavailableException $e ){
// Please handle me
}If you want to include the VAT number validation directly in your existing Form Requests / Validations, use the vat_number validtion rule.
Example:
$rules = array(
'first_name' => 'required',
'last_name' => 'required',
'company_vat' => 'vat_number'
);
$validator = Validator::make(Input::all(), $rules);Important: The validator extension returns false when the VAT ID Check SOAP API is unavailable.
If you want to use this package in combination with Laravel Cashier you can let your billable model use the BillableWithinTheEU trait. Because this trait overrides the getTaxPercent method of the Billable trait, we have to explicitly tell our model to do so.
use Laravel\Cashier\Billable;
use Mpociot\VatCalculator\Traits\BillableWithinTheEU;
use Laravel\Cashier\Contracts\Billable as BillableContract;
class User extends Model implements BillableContract
{
use Billable, BillableWithinTheEU {
BillableWithinTheEU::getTaxPercent insteadof Billable;
}
protected $dates = ['trial_ends_at', 'subscription_ends_at'];
}By using the BillableWithinTheEU trait, your billable model has new methods to set the tax rate for the billable model.
Set everything in one command:
setTaxForCountry($countryCode, $company = false)
Or use the more readable, chainable approach:
useTaxFrom($countryCode)— Use the given countries tax rateasIndividual()— The billable model is not a company (default)asBusiness()— The billable model is a valid company
So in order to set the correct tax percentage prior to subscribing your customer, consider the following workflow:
$user = User::find(1);
// For individuals use:
$user->useTaxFrom('NL');
// For business customers with a valid VAT ID, use:
$user->useTaxFrom('NL')->asBusiness();
$user->subscription('monthly')->create($creditCardToken);Right now you'll need to show your users a way to select their country - probably a drop down - to use this country for the VAT calculation.
This package has a small helper function, that tries to lookup the Country of the user, based on the IP they have.
$countryCode = VatCalculator::getIPBasedCountry();The $countryCode will either be false, if the service is unavailable, or the country couldn't be looked up. Otherwise the variable contains the two-letter country code, which can be used to prefill the user selection.
Phew - so you know how to use this class, built your fancy payment form and now...? Well - you want to display the correct prices to your users and want it to update dynamically. So go ahead, add some routes, write some Javascript and in no time you'll be up and running, right?
Or you use the built in routes and vat_calculator.js library.
The VAT Calculator JS library will automatically:
- Calculate taxes whenever the selected country value changes
- Automatically validate VAT-IDs / VAT numbers and use it for the calculation
- Prefill the user's country with the IP based country
The Javascript library has no dependencies on third party frameworks.
In order to use the Javascript helper you need to publish the package files first. Go ahead and type:
$ php artisan vendor:publish --provider="Mpociot\VatCalculator\VatCalculatorServiceProvider"Now you have a file called vat_calculator.js in your public/js folder.
Add the published javascript file to your payment form.
<head>
...
<script type="text/javascript" src="/js/vat_calculator.js"></script>
</head>By default, the VAT Calculator JS script is looking for a form with the ID payment-form.
This form needs a data-amount attribute specifying the amount to use for the tax calculation in cents (just like Stripe uses it).
So your form should look like this, when you would calculate the taxes for 24.99 €
<form method="post" id="payment-form" data-amount="2499">Next up, you need a dropdown to let your users select their billing country. This select field needs the data-vat="country" attribute, so that the VAT Calculator JS knows, where to look for country codes.
Since there are also quite a few VAT rate exceptions for specific regions or cities, it is highly recommended to add an input field to collect postal codes.
This field needs a data-vat="postal-code" attribute.
And last but not least, to automatically validate VAT Numbers / VAT IDs you can have an input field with the data-vat="vat_number" attribute specified.
So your form will look like this:
<form method="POST" id="payment-form" data-amount="2499">
<div class="form-row">
<label>
<span>Country</span>
<select data-vat="country">
<option value="US">United States</option>
<option value="GB">United Kingdom</option>
<option value="DE">Germany</option>
<option value="FR">France</option>
<option value="IT">Italy</option>
<option value="ES">Spain</option>
<option value="CA">Canada</option>
<option value="AU">Australia</option>
</select>
</label>
</div>
<div class="form-row">
<label>
<span>Postal Code</span>
<input data-vat="postal-code"/>
</label>
</div>
<div class="form-row">
<label>
<span>VAT Number</span>
<input data-vat="vat-number"/>
</label>
</div>
</form>To display the live tax calculation, you can use the classes vat-subtotal, vat-taxrate, vat-taxes and vat-total on any DOM element and VAT Calculator JS will automatically set the inner HTML content for you.
Example:
<strong>Subtotal</strong>: € <span class="vat-subtotal"></span>
<strong>Tax rate</strong>: <span class="vat-taxrate"></span>%
<strong>Taxes</strong>: € <span class="vat-taxes"></span>
<strong>Total</strong>: € <span class="vat-total"></span>| Attribute | Description | Required |
|---|---|---|
data-amount |
Use this attribute on the form you want to use for live calculation. It's the price in cent used for the calculation. |
Yes |
In order to calculate the right taxes, you need to add some extra inputs to your payment form.
All these fields need to have a data-vat attribute. You need to include at least the country.
| Attribute | Description | Required |
|---|---|---|
country |
Customer’s country (2-letter ISO code). | Yes |
postal-code |
Customer's postal code | No Highly recommended |
vat-number |
Billing VAT number | No |
Use VATCalculator.init('#my-selector') to initialize the live calculation on a different form.
Use VATCalculator.setCurrencyFormatter to use a different method to format the calculated values for the HTML output.
This function will receive the calculation result as a parameter.
Example:
VATCalculator.setCurrencyFormatter(function(value){
return value.toFixed(2) + ' €';
});Call VATCalculator.calculate() to trigger the calculation manually. For example when you change the data-amount attribute on your form.
In order for VAT Calculator JS to work properly, these routes will be added to your application. If you don't want to use the Javascript library, you can of course disable the routes in the configuration file.
| Method | Route | Usage |
|---|---|---|
GET |
vatcalculator/tax-rate-for-country/{country}/{postal-code} |
Returns the VAT / tax rate for the given country (2-letter ISO code). |
GET |
vatcalculator/country-code |
Returns the 2-letter ISO code based from the IP address. |
GET |
vatcalculator/validate-vat-id/{vat_id} |
Validates the given VAT ID |
GET |
vatcalculator/calculate |
Calculates the gross price based on the parameters: netPrice, country and vat_number |
By default, the VAT Calculator has all EU VAT rules predefined, so that it can easily be updated, if it changes for a specific country.
If you need to define other VAT rates, you can do so by publishing the configuration and add more rules.
The configuration file also determines wether you want to use the VAT Calculator JS routes or not.
Important: Be sure to set your business country code in the configuration file, to get correct VAT calculation when selling to business customers in your own country.
To publish the configuration files, run the vendor:publish command
$ php artisan vendor:publish --provider="Mpociot\VatCalculator\VatCalculatorServiceProvider"This will create a vat_calculator.php in your config directory.
