Well the subject line says state not province.
As for adjustments, IIRC and your using QB payroll, if you change the rate the next time you submit payroll QB will generate an adjusting entry. I think it only does it for the current quarter however. Longer than that and I would contact QB Payroll's support line and ask for help. It may be to the point where you are going to get a bill from your state tax agency anyway.
QB will actually correct on a YTD and to a lesser extent QTD basis, if the rates are setup correctly. Your problem is that you reach a quarter end with bad data. That use to be referred to as GIGO. Garbage in-Garbage Out. You may/should set up the rates correctly then recalculate the last paycheck for the quarter in question. QB actually supports different rates for different quarters depending on versions. Sounds like you fudged things up and are now blaming the SW for what you told it to do. Mistakes happen; accept the blame.
No, not a journal entry...a payroll liability adjustment. Go to your help index in Quickbooks, type in 'payroll liabilities', select 'adjusting' from the list and then display. Select 'adjusting payroll liabilities' and you will find instructions on how to handle this. You will be able to adjust by period, whether by pay period, month, quarter or whatever date range you choose and it will not require have to recreate the paychecks.
