- 15 - Respondent determined that petitioner is liable under section 6651(a)(1) for his failure to file returns for 1986 through 1988. In addition to the facts presented in this case, respondent pleaded and relies upon the doctrine of collateral estoppel to establish petitioner's liability under section 6651(a)(1). This argument is based upon the fact that petitioner was convicted under section 7203 of willful failure to file income tax returns for 1986 through 1988. Section 6651(a)(1) imposes a 5-percent addition to tax each month for failure to file a tax return. The addition is not to exceed 25 percent in the aggregate. A section 6651(a)(1) addition to tax is warranted where a taxpayer fails to file a timely return unless the taxpayer shows that his failure to do so was due to reasonable cause and not due to willful neglect. Where the taxpayer exercised ordinary business care and prudence and was nevertheless unable to file the return within the prescribed time, the delay is deemed due to reasonable cause. Sec. 301.6651-1(c), Proc. & Admin. Regs. As previously noted, the doctrine of collateral estoppel is intended to avoid repetitious litigation by precluding the relitigation of any issue of fact or law that was actually litigated and that culminated in a valid and final judgment.
