Taxing Previous-Year Sales with State Tax Codes - U.S. Edition
By importing the NetSuite state sales tax codes, you can assign the correct tax information to customers in several states that charge tax by customer location.
NetSuite can automatically match your shoppers' ship-to address on the web store with the closest matching tax code from these states to calculate the correct tax.
If the state tax rate was changed today and you enter a previous-year transaction, NetSuite uses today's tax rates. You can overwrite this rate by manually entering the previous rate on the transaction.
