If you are using BWv6 PR you must be on Service Pack 12 to process Year End. Then, before you process the first PR for 2007, you must install Service Pack 13. This Service Pack contains the Early Tax Table Updates.
Do not install Service Pack 13 until you have run your final payroll and printed your Form W-2s for 2006.
Also, remember to check your SUI Rate in PR > Taxes > Maintain Tax Tables after installing any service pack as it may be altered by the service pack.
Please call 303-670-2073 if you want assistance with this process.
