March 2026: Investigating: Issues with Tax Calculation
QuickBooks Online experienced a major incident where taxes were not being applied to transactions, preventing users from creating invoices, estimates, and purchase orders, and causing the platform to run slowly with frequent freezing. Users reported that sales tax calculations disappeared entirely, transactions couldn't be edited or posted, and tax information wasn't displaying properly on invoices. The issue was resolved after 1.3 hours of investigation and remediation.
