How can I retrieve taxCodes details from Netsuite using SuiteQL? When I query

salestaxitem

I don't get information like taxcode, rate, subsidiary, etc, instead:

SELECT *
FROM salestaxitem
WHERE rownum = 1

Result:

{
  "custrecord_4110_triplicate": "F",
  "custrecord_notional_tax_credit_account": null,
  "custrecord_4110_purchaser_issued": "F",
  "custrecord_4110_nondeductible_account": null,

}

Can anyone advise? Thanks!

Would not be shocked if its not exposed to query.
