From Tax Document You have to Use TaxDocumentLauncher Class.

IF you are using TaxGroup and TaxItemGroup::
private TaxValue getTaxPercent(TaxGroup _taxGroup, TaxItemGroup _taxItemGroup)
{

TaxData taxData;
select firstonly TaxCode from taxGroupData
index hint TaxGroupIdx

select firstonly TaxValue from taxData where taxData.TaxCode == taxGroupData.TaxCode;
return taxData.TaxValue;
}
Tax::calcTaxAmount(purchLine.TaxGroup, purchLine.TaxItemGroup, Systemdateget(), purchLine.CurrencyCode, purchLine.LineAmount, TaxModuleType::Purch);
