I have a similar setup for my quarterly accounting tasks - I just have
them scheduled a year in advance so they don't bother my agenda views.
I copy that subtree which moves it forward another year.  I keep the
data in-band.

On ** TODO Q1 Accounting 2010

I do C-c C-x c, create 1 clone, and move it forward +1y

This makes 2 copies actually - the one for next year _and_ moves the
repeating task forward another year.  Then All I do is change the year
on the top-level task and I'm done.

Then I can work on the entry without the +1y repeater.

After the copy (and editing the years on the Q1 Accounting YYYY task) my
file looks like this:
