Is the preferred payout to new addresses in effect?  I see on bitcointax.info that there are choices like on spending Bitcoin, last in first out; or first in first out or averaging.  It says if Bitcoins are mixed in an address they can't be separated out.  There is suppose to be a tax advantage to one or another scheme.  So, wanting us to use new addresses might be to our advantage eventually aside from the reduced ripoff potential.
