What country is this for? I've had to work on some Canadian tax changes in the past and it's a bit confusing. Here are some screenshots that I saved for my own reference, hopefully it will clarify the linkage. This is FTXP for one of the CA provinces - note that Tax Code and Valid from are important as well as the rate, of course:

This is he corresponding VK11, note that it also has Tax Code that should match with FTXP entries (as well as country/region, of course):

This entry is for the pricing condition CTXJ, conditions may differ based on the country. In this example the rate was changing stating from 4/1/2013, so I updated FTXP, expired existing condition entries and created new ones effective from that date.
If there is still an issue make sure to check the pricing determination analysis.
