If you are just using the basic features, then you are never "required" to upgrade.
However, if you want to use something that is an Intuit "service", such as the payroll services, or an integrated merchant services, then you will have to upgrade to QB 2012 probably some time in May of this year (for QB 2009).
They haven't announced the date yet, but it will come soon...
