Tax Book retirements

Our Corporate and Tax books have different calendars and our corporate book ended the year on December 29 while the tax book ends on December 31.  We had assets that have a retirement date of December 30 and they retired on the corporate book in 2013  However, per the tax calendar they should have retired in 2012.  When we do a periodic mass copy, we get an error indicating that the assets should have been retired in the previous year.

How do we now retire these assets on the tax book in an automated manner, there are close to 2000 assets that need to be retired, so it is not feasible to manually retire them on the tax books.
