In over 30 years - - had my first client NOT get the refund OR EIC on her daughter who had turned 25. The letter from the IRS came 2 weeks after her hugely reduced anticipated refund. After sending in all pertinent information and verification from the Dr. - - -it took 6 months to get the rest of the refund. Hopefully - - -this is a one shot deal, and the IRS will keep the information on file.
