我为 Magento 创建了一个附加费模块，它为报价添加了一个自定义总计字段。附加费输入到 Magento 中，包括税。我已成功获得将附加费添加到报价中的模块，并且结帐页面上的总计是正确的。

我的问题是在尝试对附加费征税以使其包含并显示在结帐页面的税字段中时出现。目前它只包括产品税和运费。

我已经设法计算了附加费的税款，但无法将税款应用于报价，以便将其显示在税款字段中，但也不认为我的方法是完全正确的。任何帮助将非常感激。

我设法使用以下代码解决了这个问题。不是最好的解决方案，但花了几个小时试图做到这一点并且没有快速得到任何地方。Asterix 需要更换。

class *****_Deposits_Model_Quote_Address_Total_Surcharge extends Mage_Sales_Model_Quote_Address_Total_Abstract {

 protected $_taxConfig = null;

 public function __construct()
 {
    $this->setCode('surcharge_price');
    $this->_taxConfig      = Mage::getSingleton('tax/config');
    $this->_store = Mage::app()->getStore();
 }

 protected function _calculateTax(Mage_Sales_Model_Quote_Address $address)
{
    $calculator     = Mage::getSingleton('tax/calculation');
    $calculator->setCustomer($address->getQuote()->getCustomer());

    $inclTax        = $this->_taxConfig->priceIncludesTax($this->_store);

    $taxRateRequest = $calculator->getRateRequest(
        $address,
        $address->getQuote()->getBillingAddress(),
        $address->getQuote()->getCustomerTaxClassId(),
        $this->_store
    );

    $taxRateRequest->setProductClassId(Mage::getStoreConfig('*****/surcharges/tax_class', $this->_store));

    $rate = $calculator->getRate($taxRateRequest);

    if($rate > 0.0) {
      $baseTax = $calculator->calcTaxAmount($address->getBaseSurchargePriceAmount(), $rate, $inclTax, true);
      $tax = $address->getQuote()->getStore()->convertPrice($baseTax, false);

      $address->addTotalAmount('tax', $tax);
      $address->addBaseTotalAmount('tax', $baseTax);

      $rates = array();
      foreach ($address->getAppliedTaxes() as $rate) {
        $rate['amount'] = $rate['amount'] + $tax;
        $rate['base_amount'] = $rate['base_amount'] + $baseTax;
        $rates[] = $rate;
      }

      $address->setAppliedTaxes($rates);

      if($inclTax) {
        $address->setGrandTotal($address->getGrandTotal() - $tax);
        $address->setBaseGrandTotal($address->getBaseGrandTotal() - $baseTax);
      }
    }

}
