Taxable Revenue United States
You can also look at your G/L Ledger for the tax account you have set up.
We found that A/R was adding tax as an adjustment before posting; after
invoicing through Order Entry, and posting it to the tax account when the
sales department "forgot" to add tax. It all works out in the end - but the
Tax Revenue report did not match our G/L, and the G/L was more accurate.
