Petitioner conceded certain determinations that respondent made in the notice. As a result, petitioner has acknowledged that an underpayment exists for his taxable year 1999. With respect to the accuracy-related penalty under section 6662(a) that respondent determined for petitioner’s taxable year 1999, petitioner testified: I keep as accurate records as I always have. I use a computer program to do my taxes. I’m pretty precise about what I put in there and back it up to the best of my ability. I’ve done this for 30 years. Well, not computerized, but I’ve used a computer since 1988 doing my taxes. * * * * * * * * * * I always go through it, the computer program will check it for any discrepancies, and even then I will go back through it and check it again. So all the calculations are done by the computer, but I do double- check, and the computer will flag anything that is a discrepancy. The record in this case does not contain any of the records that petitioner testified he maintained. We are not required to, and we shall not, accept petitioner’s uncorroborated, self- serving, and conclusory testimony about maintaining records. See Lerch v.
