"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

update tbl
set columnname = 'TAXC-00000002'
where columnname = 'TAXC-00000001'
So if your table name is invoice and column name is taxcode, then

update invoice
set taxcode = 'TAXC-00000002'
where taxcode = 'TAXC-00000001'

or to update all of them regardless of whether they previously had the value 'TAXC-00000001', then

update invoice
set taxcode = 'TAXC-00000002'
