Which payroll items in QuickBooks Desktop don't convert automatically to QuickBooks Online?

The individual paycheck detail in QuickBooks Desktop does not convert automatically to QuickBooks Online due to the way earnings and deductions are structured in the two systems. QuickBooks Desktop provides a detailed breakdown of each paycheck, including individual hours worked, rates, deductions, and net pay, which can vary widely from one period to another.

When transitioning to QuickBooks Online, the focus is on maintaining summarized payroll data rather than detailed transaction history. This approach keeps the data manageable in the new environment, as QuickBooks Online is designed to streamline processes and reduce complexity.

In contrast, tax liability payments, company payroll information, and local tax settings are typically held at a more summarized level, making them more conducive to automatic conversion between the two platforms. This helps ensure that essential payroll functions remain functional after migration, while individual paycheck details—often unique to each employee and each period—are not retained in the same format, necessitating manual entry or adjustment post-conversion.
