2. After you change the report option, you may see tax calculation difference if the pay date and pay period date of your first paycheck are not in the same year,
For example: check# 6001, pay period 12/1/2017 to 12/31/2017, paid on 1/2/2018
By pay period ending date, it is the last paycheck of 2017.
If you use the pay date: It is the first paycheck of 2018.
3. After you change the report option, review the report before you add any new data. If there is any issue, you can switch the report option back. There will be no changes on your data.
