I want to add custom service tax with the order i am try this
TaxRate taxRate = new TaxRate();
taxRate.setIsDefault(true);
taxRate.setName("service");
taxRate.setRate(30l);
List<TaxRate> taxRates = new ArrayList<>(); taxRates.add(taxRate);
lineItem.setTaxRates(taxRates);
orderConnector.addServiceCharge(mOrder.getId(),"service");
to add service tax i think addservicecharges not add tax within order ,it take default service charges is their any suggestion ?
