Adding Tax and Jurisdiction in EPiServer Commerce through Code

In one of my project I wanted to add the Tax Jurisdiction, Jurisdiction Group and Tax value through code, instead of editor going through commerce back-end system.

Therefore, i wrote little Migration Step to add Australian Tax Jurisdiction Group, Jurisdiction and Value.

[ServiceConfiguration(typeof(IMigrationStep))]
    public class ImportAustraliaTreasureSiteContent : IMigrationStep
    {
        public bool Execute(IProgressMessenger processMessenger)
        {
            _progressMessenger =  processMessenger;
            _progressMessenger.AddProgressMessageText("Adding/Updating Australia Market, Warehouse, Tax, Shipping and Payment Provider", false, 0);
            try
            {   /* Adding Tax */
                _progressMessenger.AddProgressMessageText("Adding/Updating Australia Jurisdiction and Tax", false, 0);
                AddJurisdictionAndTax(new MarketId("AUS"));

            }
            catch (Exception exception)
            {
                processMessenger.AddProgressMessageText("ImportTreasureSiteContent failed: " + exception.Message + "Stack trace:" + exception.StackTrace, true, 0);
                Log.Fatal(exception.Message, exception);
                return false;
            }
            return true;
        }

In AddJurisdictionAndTax we will first delete any existing australian Tax and Jurisdiction and then will re-add it again.

private static void AddJurisdictionAndTax(IMarket market)
        {
            /* Get Jurisdiction DTO to add/remove jurisdiction  */
            var jurisdictions = JurisdictionManager.GetJurisdictions(JurisdictionManager.JurisdictionType.Tax);

            RemoveAustralianJurisdictionAndTax(jurisdictions, market);
            AddAustralianJurisdictionAndTaxValue(jurisdictions, market);
        }

Removing the Existing Australian Jurisdiction and Tax

  private static void RemoveAustralianJurisdictionAndTax(JurisdictionDto jurisdictions, IMarket market)
        {
            var australiaJurisdictions = jurisdictions.Jurisdiction.Where(w => w.CountryCode == market.MarketId);
            var jurisdictionGroups = JurisdictionManager.GetJurisdictionGroups(JurisdictionManager.JurisdictionType.Tax);

            /* Get relation many to many table for australian jurisdiction */
            var relationsGrp = australiaJurisdictions.SelectMany(s => s.GetJurisdictionRelationRows());

            /* Save id for future jurisdiction group use */
            var relations = relationsGrp.Select(s => new { s.JurisdictionGroupId, s.JurisdictionId }).ToList();
            var ausJuriGrps =
                jurisdictionGroups.JurisdictionGroup.Where(
                    s => relations.Select(g => g.JurisdictionGroupId).Contains(s.JurisdictionGroupId));

            /* Deleting manay to many middle table */
            foreach (var rel in relationsGrp)
            {
                rel.Delete();
            }

            /* Deleting australian jurisdiction */
            foreach (var ausJuri in australiaJurisdictions)
            {
                ausJuri.Delete();
            }


            /* Get JurisfictionsGroup belong to Australian Jurisdictions */
            foreach (var ausJuriGrp in ausJuriGrps)
            {
                ausJuriGrp.Delete();
            }

           /* Saving delete objects */
            JurisdictionManager.SaveJurisdiction(jurisdictions);

            /* Fetching Tax DTO belongs to Australian Language */
            var taxDto = TaxManager.GetTaxDto(TaxType.SalesTax);
            var taxLanguage = taxDto.TaxLanguage.FirstOrDefault(w => w.LanguageCode == market.DefaultLanguage.Name);
            if (taxLanguage != null)
            {
                /* Deleting Australian language and Tax relation */
                taxLanguage.Delete();

                /* Get tax */
                var tax = taxDto.Tax.FirstOrDefault(t => t.TaxId == taxLanguage.TaxId);

                /* Deleting Australian Tax */
                tax.Delete();
            }
            TaxManager.SaveTax(taxDto);
        }

Adding Australian Jurisdiction and Tax

   private static void AddAustralianJurisdictionAndTaxValue(JurisdictionDto jurisdictions, IMarket market)
        {
            /* Add jurisdictions row */
            var jrow = jurisdictions.Jurisdiction.AddJurisdictionRow("Australian Tax", "NSW", market.Countries.FirstOrDefault(),
                 (int)JurisdictionManager.JurisdictionType.Tax, null, null, null, null,
                 null, null, AppContext.Current.ApplicationId, "Australian Tax");

            /* Add jurisdiction group row */
            var jgrow = jurisdictions.JurisdictionGroup.AddJurisdictionGroupRow(AppContext.Current.ApplicationId, "Australian Tax", (int)JurisdictionManager.JurisdictionType.Tax, "Australian Tax");

            /* Add relation between jurisdiction and jurisdiction group */
            var jrela = jurisdictions.JurisdictionRelation.AddJurisdictionRelationRow(jrow, jgrow);

            JurisdictionManager.SaveJurisdiction(jurisdictions);

            /* Add Tax */
            var taxDto = TaxManager.GetTaxDto(TaxType.SalesTax);
            var trow = taxDto.Tax.AddTaxRow((int)TaxType.SalesTax, "Australian Tax", 0, AppContext.Current.ApplicationId);
            var tlrow = taxDto.TaxLanguage.AddTaxLanguageRow("Australian Tax", market.DefaultLanguage.Name,
                trow);
            var tvrow = taxDto.TaxValue.AddTaxValueRow(10d, trow, "Sales", jgrow.JurisdictionGroupId, DateTime.Now,
                Guid.Empty);
            TaxManager.SaveTax(taxDto);
        }

Migraiton Step only runs once in life. So once you initialize a site for the first time. Migration step will kick in and will add tax value.
