Example 1. A filed his income tax return for the calendar year 1955 on May 15, 1956, not having been granted an extension of time for such filing. His failure to file on time was not due to reasonable cause. The return showed a liability of $1,000 and it was determined that A is liable under section 6651 for an addition to such tax of $50 (5 percent a month for 1 month). The provisions of subchapter B of chapter 63 (deficiency procedures) do not apply to the assessment and collection of the addition to the tax since such provisions are not applicable to the tax with respect to which such addition was asserted, there being no statutory deficiency for purposes of section 6211.
Example 2. Assume the same facts as in example 1 and assume further that a deficiency of $500 in tax and a further $25 addition to the tax under section 6651 is asserted against A for the calendar year 1955. Thus, the total addition to the tax under section 6651 is $75. Since the provisions of subchapter B of chapter 63 are applicable to the $500 deficiency, they likewise apply to the $25 addition to the tax asserted with respect to such deficiency (but not to the $50 addition to the tax under example 1).
