Tests Coding Standards Latest Stable Version Total Downloads

Handle all the hard stuff related to EU MOSS tax/vat regulations, the way it should be. Integrates with Laravel and Cashier — or in a standalone PHP application. Originally created by Marcel Pociot.

// Easy to use!
VatCalculator::calculate(24.00, $countryCode = 'DE');
VatCalculator::calculate(24.00, $countryCode, $postalCode);
VatCalculator::calculate(71.00, 'DE', '41352', $isCompany = true);
VatCalculator::getTaxRateForLocation('NL');

// Check validity of a VAT number
VatCalculator::isValidVATNumber('NL123456789B01');

Warning

This package does not provide any promises for correctly calculated taxes. You are still responsible to making sure that any calculated tax is correct for your use case. If you're uncertain if a certain tax is correct or not, it's best that you talk to an accountant.

Requirements

  • PHP 7.3 or higher
  • (optional) Laravel 6.0 or higher

Installation

Install the package with composer:

composer require mpociot/vat-calculator

Standalone

You can also use this package without Laravel. Simply create a new instance of the VatCalculator and use it. All documentation examples use the Laravel Facade code, so make sure not to call the methods as if they were static methods.

use Mpociot\VatCalculator\VatCalculator;

$vatCalculator = new VatCalculator();
$vatCalculator->setBusinessCountryCode('DE');
$grossPrice = $vatCalculator->calculate(49.99, $countryCode = 'LU');

Upgrading

Please refer to the upgrade guide when upgrading the library.

Usage

Calculate the gross price

To calculate the gross price use the calculate method with a net price and a country code as parameters.

$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);

Receive more information

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(); // 4.56

Receive all tax rates for a given country

To receive an array with all available tax rates for a given country, use the getTaxRatesForCountry method.

VatCalculator::getTaxRatesForCountry('DE'); // ["high" => 0.19, "low" => 0.07]

Validate EU VAT numbers

Prior 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')) {
    // This country code requires VAT collection...
}

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) {
    // The VAT check API is unavailable...
}

Alternatively, it is also possible to validate only the format of the VAT Number specified by VIES. This is useful, if you do not want to wait for a response from the SOAP API.

// This check will return false because no connection to VIES could be made...
$validVAT = VatCalculator::isValidVATNumber('NL 123456789 B01');

// This check will return true because only the format is checked...
$validVAT = VatCalculator::isValidVatNumberFormat('NL 123456789 B01');

Get EU VAT number details

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) {
    // The VAT check API is unavailable...
}

UK VAT Numbers

Note: Validating UK VAT numbers requires registering your application with the HMRC Developer Hub. Please follow the official HMRC API Documentation for details on authentication and setup.

UK VAT numbers are formatted a little differently:

try {
    $vat_details = VatCalculator::getVATDetails('GB 553557881');
    print_r($vat_details);
    /* Outputs
    array(3) {
        ["name"]=>
            string(26) "Credite Sberger Donal Inc."
        ["vatNumber"]=>
            string(9) "553557881"
        ["address"]=>
            array(3) {
                ["line1"]=>
                    string(18) "131B Barton Hamlet"
                ["postcode"]=>
                    string(8) "SW97 5CK"
                ["countryCode"]=>
                    string(2) "GB"
            }
    }
    */
} catch (VATCheckUnavailableException $e) {
    // The VAT check API is unavailable...
}

🔐 Configuration

To use the UK VAT validation feature, you'll need to register your application with HMRC and set the following environment variables in your .env file:

HMRC_CLIENT_ID="your-client-id"
HMRC_CLIENT_SECRET="your-client-secret"

Laravel

Configuration

By default, the VatCalculator 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.

Warning
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.

Handling SOAP Faults

If for some reason, SOAP faults happen when the VIES API is faulty, these errors will be handled gracefully and false will be returned. However, if you explicitly want to be aware of any SOAP faults you may instruct VatCalculator to throw them as a VATCheckUnavailableException. The VATCheckUnavailableException will then contain the specific message of the SOAP fault.

Set the option to true in your config file:

<?php

return [
    'forward_soap_faults' => true,
];

You can also set a timeout for the SOAP client. By default, SOAP aborts the request to VIES after 30 seconds. If you do not want to wait that long, you can reduce the timeout, for example to 10 seconds:

<?php

return [
    'soap_timeout' => 10,
];

ValidVatNumber Validation Rule

VatCalculator also ships with a ValidVatNumber validation rule for VAT Numbers. You can use this when validation input from a form request or a standalone validator instance:

use Mpociot\VatCalculator\Rules\ValidVatNumber;

$validator = Validator::make(Input::all(), [
    'first_name' => 'required',
    'last_name' => 'required',
    'company_vat' => ['required', new ValidVatNumber],
]);

if ($validator->passes()) {
    // Input is correct...
}

Warning

The validator extension returns false when the VAT ID Check SOAP API is unavailable.

Cashier Stripe Integration

Note

At the moment this package is not compatible with Cashier Stripe v13 or higher because it still relies on the old taxPercentage method which has been removed from Cashier v13. You can still use it on older Cashier Stripe versions in the meantime.

If you want to use this package in combination with Laravel Cashier Stripe you can let your billable model use the BillableWithinTheEU trait. Because this trait overrides the taxPercentage 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::taxPercentage 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 rate
  • asIndividual() — 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);
