Causes of Payroll Error PS033
Understanding the underlying cause helps you apply the correct fix. Here are the most frequent reasons:

Problems with Microsoft components like .NET Framework, MSXML, or Visual C++ can interrupt payroll operations.

If the company file is corrupted or contains internal inconsistencies, QuickBooks may fail to validate payroll data.
