New Tax changes sub pricing half way through renewal period

Hi all,

A new, higher tax is being imposed on all of our 2010/11 subscriptions as of May 1st (our launch is this week, Feb 26).  So, as of 12:01am on May 1, any subscriber who hasn't renewed will have to pay 8% more.  I need to make sure that anyone who logs onto their account online sees a revised order with the new taxes included. 

How should I do that?  Can I do a second roll-over for all unpaid subscription orders midway through our subscription renewal campain?  Any suggestions?

Thank you!!
