Additional information

• You can void FWT, FICA, SWT, and SDI deposits made this quarter and last quarter. You can also void deposits from the prior year’s final quarter.
• You can void FUTA and SUI deposits made this year or during the prior year’s final quarter.
• Voiding the tax deposit in Sage BusinessWorks doesn’t void the payment in Enhanced Tax Reporting (Aatrix).
• You can't void a prior‑year tax deposit. To fix it, enter a charge in CM, Transactions, Enter Bank Transaction, and distribute it properly. The charge automatically debits cash.
