Sales Tax Report - Voids

If you would like to have voided invoices factored in when running the sales tax report (Income -> Reports -> Billing -> Sales Tax Report), check the box labeled Include Voided Invoices. 

Voided invoices will show in the period they were created, if the report period does not include the date the invoice was deleted. If the report period only includes the date an invoice was voided, but not the date it was created, the report will show the voided invoice with reverse totals.
