Change the default calculation

By inheriting from the default implementation of the interface, DefaultTaxCalculator, you can override the calculation of get tax value and get tax category name. Just override one or several methods in the DefaultTaxCalculator.

public class TaxCalculatorOverridingDefault : DefaultTaxCalculator
      {
        public TaxCalculatorOverridingDefault(IContentRepository contentRepository, ReferenceConverter referenceConverter)
          : base(contentRepository, referenceConverter)
          { }
        protected override string GetTaxCategoryNameById(int taxCategoryId)
          {
            return string.Empty;
          }
        protected override IEnumerable<ITaxValue> GetTaxValues(string taxCategory, string languageCode, IOrderAddress orderAddress)
          {
            return new List<ITaxValue>() { new TaxValue(10, "SalesTax", "clothing", TaxType.SalesTax) };
          }
      }
