A set of interfaces and methods to clean up your application's tax calculations. The TaxCalculation class allows you to do calculations with plain numbers and objects that implement the HasTax interface on the fly.
use Spatie\TaxCalculator\TaxCalculation;
$items = $myCart->getItems(); // Should return an array of items that implement `HasTax`
TaxCalculation::fromCollection($items)->basePrice(); // 10.00
TaxCalculation::fromCollection($items)->taxPrice(); // 2.10
TaxCalculation::fromCollection($items)->taxedPrice(); // 12.10
$delivery = TaxCalculation::fromTaxedPrice(7.50, 0.21);
TaxCalculation::fromCollection($items)->add($delivery)->taxedPrice(); // 19.60Spatie is a webdesign agency based in Antwerp, Belgium. You'll find an overview of all our open source projects on our website.

You can install the package via composer:

public function basePrice(): float;
public function taxedPrice(): float;
public function taxPrice(): float;basePrice: The item's price excluding taxestaxedPrice: The item's price including taxestaxPrice: The item's tax amount (= taxedPrice() - basePrice())
public function taxRate(): float;HasTaxWithRate extends HasTax, and also has a taxRate method. This is useful for items that have a fixed tax rate, but can't be used on collections that contain items with various rates.
The HasTaxWithRate trait provides default implementations of taxPrice and taxedPrice, since they can be deducted by a simple multiplication of basePrice and taxRate.
