Facts read from this source
-
Integration purpose Report an error
“The TaxJar integration connects Younium to TaxJar for US sales tax calculation on draft invoices and reporting (order creation) when invoices are posted.”
-
Tax eligibility rule Report an error
“Tax is applied only to invoice lines whose tax template detail matches the ship-to address and has Use TaxJar enabled.”
-
Auth method Report an error
“You connect TaxJar with an API token, which you generate in TaxJar and paste into the integration settings together with a choice of sandbox or production.”
-
Sandbox production Report an error
“You choose sandbox or production when you connect, and the choice decides which TaxJar account Younium calculates and reports against.”
-
No periodic reauth Report an error
“The connection lasts until the token is revoked or replaced in TaxJar. Nothing expires on a schedule and there is no periodic reauthorisation.”
-
Out of scope Report an error
“Not in scope: address validation, exemption certificates, nexus, tax calculation on quotes.”
-
Sync scope Report an error
“Tax calculation on draft invoices Younium → TaxJar When draft invoices are generated, if tax calculation is enabled”
-
Charge custom field Report an error
“Activating also creates the charge custom field TaxJax Product Tax Code, which carries the TaxJar product tax code for a charge.”
-
Deactivation behavior Report an error
“Deactivating the integration removes the stored TaxJar settings and stops both exchanges: draft invoices are no longer sent for tax calculation, and posted invoices are no longer reported to TaxJar. Tax amounts already written onto invoices are left as they are.”
-
Settings Report an error
“DoSalesTaxCalculations Enable draft invoice tax calculation via TaxJar”
-
State filtering Report an error
“StatesForTaxCalculation is a comma-separated list of entries like ca or ca:FIN001 (spaces stripped, compared lowercase to addressTo.State).”
-
Account custom field Report an error
“Account Exemption type List Do not rename; keys sent as TaxJar exemption_type”
-
Exemption types Report an error
“non_exempt Non exempt wholesale Whole sale government Government marketplace Marketplace other Other”
-
Taxjar API calls Report an error
“Draft tax calculation (TaxForOrder — per eligible line)”
-
Ship to resolution Report an error
“Draft calculation Invoice.DeliveryAddress ?? Invoice.InvoiceAddress”
-
Tax writeback Report an error
“For tax items tied to the line’s tax template, TaxItem.Amount.Amount is set to rates.AmountToCollect (TaxJar response). Line Tax, Total, and invoice totals are recalculated and saved.”
-
Legal entity address required Report an error
“Required legal entity address fields (when calculating): country two-alpha code, zip, state, city, street — missing values throw ApiException.”
-
Credit line handling Report an error
“Credit lines on debit invoice (Subtotal.Amount < 0): reported separately via CreateRefund with transaction_id = {InvoiceNumber}_creditLines, transaction_reference_id = InvoiceNumber”
-
Posting no recalc Report an error
“Posting an invoice reports it to TaxJar but does not recalculate its tax. Tax is calculated on the draft invoice, so the amounts on a posted invoice are the ones calculated before posting.”
-
Reporting no writeback Report an error
“Reporting does not write tax back to Younium — it sends transactions already reflected on the posted invoice.”
-
