Randy has done a great job with our return the last couple of years even with complicated filing. I would recommend Randy to anyone and we gladly make the hour drive from San Clemente down to San Diego to have him handle our taxes.

It is best to take care of this sort of thing quickly, because the IRS charges interest and penalties if you wind up owing them additional tax.
