3339545 - Unexpected Tax Amount in Expense Report

An extension field in the details of expense item is created to display the tax amount. However, the tax amount is not as expected.

For example, enter an expense amount of 100 USD.

The tax rate is 1%.

The expected tax amount is 1 USD, but it turns out to be 0.99 USD.
