Hello there, cgs33. I'm here to lend a hand.
QuickBooks Online (QBO) uses exchange rate from IHS Markit, and the rate displayed in your QBO account fluctuates day by day based on the current rate. When reversing the entry next month due to a change in the home currency exchange rate, it's important to use the exchange rate applicable for the reversal date to ensure an accurate reflection of the financial impact of the currency rate change.
You may also consider contacting your accountant for expert guidance on handling this situation.
Additionally, here's an article that contains a list of payroll reports you can use to obtain information about your employees' earnings, taxes, and deductions.: Run payroll reports in QuickBooks Online Payroll.
